Web Service Task Not Showing Input
Jun 11, 2007
For the life of me I can't figure this one out. I'm trying to call a web service using the SSIS "Web Service Task". I give the Connection Manager a valid URL, download the WSDL, and go to the input pane of the "Web Service Task" options. No problems. I select my web service and pick a web method from the methods drop-down box. No problems. But where it should pop up with an input dialog box that allows you set your inputs for the web service call, nothing shows up. No errors are reported; the input pane just remains completely blank. I can inspect the WSDL with other tools (like Altova's XMLSpy) and plainly see the inputs it takes. I haven't seen a similar issue posted on this forum so I don't know if I'm going nuts or my version of SSIS is evil or what. I applied SQL Server SP1 and SP2 but it didn't change anything. I then tried to connect to one of Amazon's public web services to see if it was a problem related to our in-house WSDL formatting, and I discovered the same problem. Take for instance
http://webservices.amazon.com/AWSECommerceService/AWSECommerceService.wsdl?
I create a Web Service Task for this service and when I go to select the "ListLookup" method from the drop-down box on the input page no input parameters appear. The WSDL clearly defines this method to take a bunch of inputs. If anybody has any ideas about what's going on here I would greatly appreciate the help. Thanks.

I'm attempting to use the Web Service task to call a method provided by a vendor. The inputs are all simple types so that helps a lot, but for one input it's a string array. If I enter a single string value for a given id using the array dialog, the method works fine.
However if I try to change the input to use a variable to provide the value it fails. I'm assuming that you can't create a variable to return a string array. Please let me know if this is the case or if I'm missing something obvious ;-)
In addition, is there a way to specify a null value for an input? Currently there doesn't appear to be a way to do this in SP2. I tried leaving the string empty which didn't work and I tried using a variable with expression "NULL(DT_WSTR, 1252)" but that failed too.

Microsoft says it is possible but I just do not see how. Here is the
link to the help file where it said that variables could be pass as
input to web methods...I do not see the check box they mention on my
IDE.
Any help would be greatly appreciated.
Thanks,
Catherine

There is not a way to pass parameters to input of Web Service tasks. I heard this problem is fixed with SQL2K5 SP1 and even the online doc says that one can choose either "value" or "variable" when specifying input for web service tasks, but after I installed what-I-think-is SP1, there is still no way to do this.
If one can only specify values (hard-coded) as input to web service tasks, then this would be a very severe limitation. I hope I'm wrong, so could someone please give a pointer. Thanks

Hi,
In SSIS web service task - when you specify the Service and Method in the input tab for a WSDL file being used,
it seems to prompt for the parameters to be supplied only in the body of the WSDL file, and not the header.
I need to be able to provide security information (present in the SOAP header of the WSDL) like username, password etc..which is necessary to post any response to the web server, and I cannot see where I can give this in the input tab of the web service task.
Any help highly appreciated.
Thanks

Greetings,
Is there a way to force the parameter input area to always show even when default values are specified? I want to always display the parameter area even when I set initial parameters.
Thanks

I'm using a Row Count Task to count the number of records passing thru a particular path in my data flow. I created a package variable and referenced this variable in the Components Properties tab in the Row Count Task. I believe this is the minimum I need to do to get the row count.
However, as I explore the other tabs in the editor, I see there is something called Input Columns tab. What is this for? I didn't select anything in there and things are working fine. At first I thought that I had to choose the columns that I want to have available to me for further processing after the Row Count Task, but this isn't the case. I am able to see all my columns coming out of the Row Count Task even tho I didn't do anything in the Input Columns tab.
So, what is this setting for?

With the new improvments to the web service task, we can now use variables as arguments in web service calls. I am trying to setup a call to the amazon web service ECS. I am trying to do a simple sellerlookup. I have played with the settings and gotten nowhere. I get one of two error when I try to execute. I can always use a scripting task or write my own task, but I would like to use the built in task if it is possible. Has anyone used AWS with SSIS?
[Web Service Task] Error: An error occurred with the following error message: "Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebserviceTaskException: Could not execute the Web method.

or

Hi,
I have a SSIS package with a Sequence which Contains a Webservice Task, in the input section of this task i want to pass a User Variable as Parameter for my webmethod. but it doesn´t work, it allways sends the variable definition as string "@[User::Filename]". so i searched Microsoft Technet how to pass User Variables in Webservice Tasks and found this site: http://technet.microsoft.com/en-us/library/ms187617.aspx
which says :
"
Variable
Select the check boxes to use variables to provide inputs. "
but there is no such checkbox on the input page of my Webservice Task... there is just the Value column which i can edit... but as mentioned before when i try to set the value to a variable it doesn work
i tried the following strings in the value column:
@[User::Filename]
@Filename
User::Filename
@User::Filename
any ideas?
thanks for your help
bye

Hi Everyone,
I'm trying to do something that should be fairly straightforward, but SSIS seems to be getting confused. I have a stored procedure which takes a timestamp as an input parameter. (NOTE: It's not a DateTime that's being stored as a DBTIMESTAMP, it really is a timestamp in the SQL sense.)
The command should be something like this:
Code Block
EXEC dbo.UpdateSynchTimestamp ?
I tried to use my variable to pass the value through Parameter Mapping, but I got an unusual error:
[Execute SQL Task] Error: Executing the query "EXEC dbo.UpdateSynchTimestamp ?" failed with the following error: "An error occurred while extracting the result into a variable of type (DBTYPE_DBTIMESTAMP)". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
This is strange for a number of reasons:
1) The DBTIMESTAMP parameter has the Direction set to "Input", so it should not be interpreted as an Output or ReturnValue.
2) The Execute SQL Task has Result Set = "None", so it should not be trying to return anything.
If I change the code to include a value hard-coded it works:
Code Block
EXEC dbo.UpdateSynchTimestamp 0x00000000000013BD
It is only when a variable is involved that it breaks.
Finally, here's the Stored Procedure itself:
Code Block
CREATE PROCEDURE [dbo].[UpdateSynchTimestamp]
@NewValue TIMESTAMP
AS
BEGIN
SET NOCOUNT ON;
UPDATE ServerSettings
SET [Value] = @NewValue
WHERE [Key] = 'SynchTimestamp'
END
Doe anyone have any suggestions as to why this isn't working for me? For the time being, I have a Script Task which constructs the command text and stores it in a variable. I can't even use an Expression because the DBTIMESTAMP is not supported.
Thanks for reading this!

I've encountered a new problem with an SSIS Pkg where I have a seq. of Execute SQL tasks. My question are:
1) In the First Execute SQL Task, I want to store a single row result of @@identity type into a User Variable User::LoadID of What type. ( I tried using DBNull Type or Object type which works, not with any other type, it but I can't proceed to step 2 )
2) Now I want to use this User::LoadID as input parameter of What type for the next task (I tried using Numeric, Long, DB_Numeric, Decimal, Double none of there work).
Please give me solutions for the above two..

I need to loop the recordset returned from a ExecuteSQL task and transform each row using a Data Conversion task (or a Script Task).
I know how to loop the recordset returned by an ExecuteSQL task:
http://www.sqlis.com/59.aspx
I loop the returned recordset (which is mapped to a User variable of type System.Object) and assign the Variable Mappings in the ForEach Loop to different user variables which map to the Exec proc resultset (with names and data types).
I assume to now use these as the Available Input columns for the Data Conversion task, I drag a Data Flow task inside the For Each Loop container and double-click it, then add a Data Conversion task.
But the Input columns (which I entered in the Variable Mappings in the ForEach Loop containers) dont show up in the Available Input columns of the Data Conversion task.
How do I link the Variable Mappings in the ForEach Loop containers from the recordset returned by the Execute SQL Task to the Available Input columns of the Data Conversion task?
.......................
If this is not possible, and the advice is to use the OLEDB data flow as the input for the Data Conversion task (which is something I tried too), then the results from an OLEDB Command (using EXEC sp_myproc) are not mapped to the Available Input columns of the Data Conversion task either (as its not an explicit SQL Statement and the runtime results from a stored proc exection)
I would like to use the ExecuteSQL task to do this as the Package is clean and comprehensible. Which is the easiest best way to map the returned results from a Stored proc execution to the Available Input columns of any Data Flow transformation task for the transform operations I need to execute on each row of data?
[ Could not find any useful advice on this anywhere ]
thanks in advance!

Hi Everyone,
I haven't been able to successfully use the ADO.NET connection type to use both input and output parameters in an execute sql task containing just tsql statements (no stored procedure calls). I have successfully used input parameters on their own but when i combine it with output parameters it fails on the simplest of tasks.
I would really find it beneficial if you could use the flexibility of an ADO.NET connection type as the parameter marker and parameter name can be referenced anywhere throughout the sql statement in no particular order. The addition of an output parameter would really make it great!!
Thanks

Hi!
I have a HttpConnection with an url to an existing webservices f.ex. http://myweb/ws/ssis.asmx?wsdl
My Web Service Task is using this HttpConnection and I have specified a path for the WSDL-file, f.ex: c:SSISMyProj.wsdl
This leads to that I have to deploy the WSDL-file to exactly the same location on the Sql-server that hosts/executes the Package.
Is there a way to point out a URL or anything else? I don't want to have this dependency.

Hi,
I am an ETL Developer.Very new to web service task.I created a package where I am using For loop Container.Within the container I used Execute SQL Task (retrieve a single row using store proc).Output of the Execute SQL Task is passed to webservice task.The output of Web service task is a XML data which is used in the data flow task and transfer the xml output to flat file destination.The package works fine for a batch of hundred rows. But for a batch of 10,000 rows at a stretch the performance is very poor. The webservice can take only one input at a time. Is there any other method other than web service task to solve this problem?
Thank You

Hello All,
I am a using a web service task inside a package. I configured the url and also got the wsdl file into my local envirioment and mapped the path of the WSDL file into the package. The Test connection for the site also succeeded. The problem I am facing is as follows.
When I go to the input tab there the service name automatically comes up allright but in the Method when I use the drop down I do not see any of the functions that are listed. Am I doing something wrong? Please do advice. It is very very urgent.
Thanks in advance

Hello,
I tried to use an Web Service from SSIS (Web Service Task), this Web Service returns arrays of int and
an array of a data contract. It always returns the following error msg while selection the method after downloading
the WSDL-file:
Item has already been added. Key in dictionary: 'Arrayofint' Key being added:
'Arrayofint'.
When I remove the arrays and just use an data contract as return parameter. SSIS-project also returns the
same error message, but not with Arrayofint, instead it has the name of data contract. If I implement the
same webservice with ASP.Net everything works fine.
Is there a solution to this problem besides of using ASP.Net or a stored procedure in SQL Server, which
implements the web service access? Or has anyone has integrated a WCF web service with data contract?
Comment 06/12/16 (UH): Stored Procedures doesn't work either, since the assemblies from WCF can't be
added to SQL Server.
Thanks,
Uwe

I am trying to prove I can use SSIS to connect to a web service. The WS I am trying to connect to was developed by a vendor and covered by a NDA, but I was able to reproduce the issue with a public WS.
Here are the steps to reproduce the issue:
In the Web Services Connection Manager, I entered http://office.microsoft.com/Research/Providers/MoneyCentral.asmx?wsdl in the URL window. I am able to successfully "test" the connection
I pasted the above link into IE and saved the resulting XML as a .wsdl file on my local machine. In the Web Services Task Editor, General Tab, I specify the path to the .wsdl file and click on "Download WSDL" button. No Issues
When I click on "Input" and select "MoneyCentralRemote" from the drop-down for Service, I receive an error message saying "This version of the Web Services Description Language (WSDL) is not supported"
So the questions are:
Did I perform the above steps correctly?
What WSDL versions are supported in SSIS?
How can I tell what WSDL version was used to create the .wsdl I am trying to access?
If the WSDL is an unsupported version, is there a work-around to fix the issue?

Executing the simplest of Web Service tasks consistently fail with the error: "Object reference not set to an instance of an object".
This really isn't a very helpful message for this task, and there's nothing from the task editor that can be adjusted. I am using SP1, the HTTP connection to the service tests OK, the WSDL file downloads OK, and the methods and parameters appear OK.
Suggestions?

A package contains a web service task which makes a call to a web service. This call may take some time to complete (maybe up to 5-10 minutes). In it's simplest form, my package is reporting a failure. Error message is
"Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebserviceTaskException: The Web Service threw an error during method execution. The error is: The operation has timed out.
I can find no way to set the timeout period of a SSIS web service task. Is this possible, or is it something which Microsoft is addressing?

I am trying to configure a web service task. I have created the HTTP Connection, and specified the WSDL. When I select the service name on the Input page, I get the error ...
Item has already been added. Key in dictionary: 'BaseTO' Key being added: 'BaseTO'
I have previously been able to successfully configure the task in a separate project.
The Webservice methods take and return complex parameters. e.g. BaseTO above is custom transfer object type which the other transfer objects inherit. It is a List<> of some type of this object which is being passed/returned from the service.
I suspect these complex types will not be supported anyway but am puzzled by the original problem.
Any help much appreciated.

I have a web service running from multipule locations. Its the same service at all the locations. I am trying to use a for loop to execute a web service task dynamically setting the url of the http connection manager that the webservice task uses. I have succesfuly done this, but the task is using a url from the wsdl file that is stored locally to access the service regardless of what the url is in the http connection manager is. Is there any way to force the web service task to download the wsdl file every time it's executed or is there an easier way for accomplishing this?

hi all,
I am creating a simple ssis package in business inteligence studio 2005. In that i am going to use an webservice task. I have assigned the wsdl and the configured the HTTP connection too. I have selected the service name and the method to be called. I have to give 2 input values for the web method. I need to make it dynamic. so i have planned to assign the variables for those input parameters. But In the webservice editor window there is only the provision to assign the vales for the input parameters. how can i assign valriables instead of setting the values directly.
I have also find in blogs that there will be a variable checkbox available. But i cant find the one..
Any one plz let me know the solution for this
Thankz

I have been struggling with a problem with the Web Service Task. I have a package that uses this and has to authenticate to the web service. This works fine on my development server but if I export the package to file and run from another computer / user, the package fails as it doesn't log in to the web service. I have found the problem to be the package was set to default of EncryptSensitiveWithUserKey and I understand why this is. If I change to use EncryptSensitiveWithPassword, it prompts for creds and works fine. My question is how do I use a package configuration file to use different creds (there is not password option for the http connection) so I can standardize on use of config files for this operation. Thanks.

Hi all,
I have created a Web service and I want to call a single method from it to extract data. For this reason I use the SSIS "Web Service Task" . The problem is that the xml output file from the web service task does not look in the proper way. When I invoke my web service method in the browser the result looks like the following:
<?xml version="1.0" encoding="utf-8" ?>
- <ArrayOfBooking xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://tempuri.org/">

My problem is that I cannot create a xsd schema for the xml file output from the "web service task", and because of this I cannot insert the data in the xml file into the Database, because the xsd schema is reqired by the XML Source which I use in my DataFlow task for inserting the data.
Do you have any ideas how to solve this strange problem?

Hello,
I have a web service contained in a apache tomcat server and I try to execute a webservice and store the result into a flat file.But I have a message saying me that there is an error in the xml document.
I suppose that it's my wsdl file.
But my wsdl file is fine!!!
Can the error come from the provider of the web service (Apache Tomcat).
I suppose that because in every example on the internet I didn't see an example an tomcat or other web server use.

I am trying to call a web service using the web service task and passing it variables, but even when I set variables to be Strings/any other data type, they always get passed out as objects. The call is then rejected based on the fact that there is no web service that accepts those parameter types. If there is a workaround to this problem, that would be great, otherwise I think I'm going to have to call the web services in a script task. Would someone please give me an example of the steps necessary to call a web service from the script task?
Thank you,
