Call Web Service From Script Task
Jul 2, 2007
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,
James Mac William

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. The error is: Object reference not set to an instance of an object.. at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebMethodInvokerProxy.InvokeMethod(DTSWebMethodInfo methodInfo, String serviceName, Object connection) at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTaskUtil.Invoke(DTSWebMethodInfo methodInfo, String serviceName, Object connection, VariableDispenser taskVariableDispenser) at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTask.executeThread()".
or

Hi,
I m trying to use the web services task, but when i try to run it i got the following error
[Web Service Task] Error: An error occurred with the following error message: "Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebserviceTaskException: Could not execute the Web method. The error is: Object reference not set to an instance of an object.. at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebMethodInvokerProxy.InvokeMethod(DTSWebMethodInfo methodInfo, String serviceName, Object connection) at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTaskUtil.Invoke(DTSWebMethodInfo methodInfo, String serviceName, Object connection, VariableDispenser taskVariableDispenser) at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTask.executeThread()".
This is probably because i never worked with this task, even so, does anyone knows what might be wrong?
I got a connection a wsdl, i can configure the service, method and variables(i use fixed values), and i configure the output to a variable with the type object(i have tryed string and int)
I even can download the wsdl file, but the error seems to be in the connection
Thanks

Hello! I have the following problem. I developed CLR Stored Procedure "StartNotification" and deploy it on db. This sp calls external web service. Furthermore, this sp is called according with SQL Server Agent Job's schedule. On my PC SQL Server works under Local System account and this web service is called correctly (Executed as user: NT AUTHORITYSYSTEM). But on ther other server the following exception is raised during job running:
Date 17.04.2007 16:42:10
Log Job History (FailureNotificationJob)
Step ID 1
Server MSK-CDBPO-01
Job Name FailureNotificationJob
Step Name MainStep
Duration 00:00:00
Sql Severity 16
Sql Message ID 6522
Operator Emailed
Operator Net sent
Operator Paged
Retries Attempted 0
Message
Executed as user: CORPmssqlserver.
A .NET Framework error occurred during execution
of user defined routine or aggregate 'StartNotification':
System.Security.SecurityException: Request for the permission of type
'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b77a5c561934e089' failed. System.Security.SecurityException:
at System.Security.CodeAccessSecurityEngine.Check(Object demand,
StackCrawlMark& stackMark, Boolean isPermSet)
at System.Security.CodeAccessPermission.Demand()
at System.Net. The step failed.
What is the reason of this behaviour? Unfortunately I do not have direct access to this server.
I have the following guesses:
1) CORPmssqlserver may have not enough permissions to call web service
2) Something wrong with SQL Server account's permissions
2) Something wrong with SQL Server Agent account's permissions
I will take the will for the deed. Thanks.

I have two databases with two identical tables in seperate physical locations. I want database B tables to be updated automatically when database A tables change. Is there a way to call a web service from SQL to make this happen? Or is there a better way to do this? I would really like it to get the rows that were modified and then copy only those rows to the other database tables. If anyone knows if this can be done please let me know. Thank you.

With regular .net web services in vb.net I can expose the service and call it like this:
http://server/EnrollmentLookup/EnrollmentService.asmx/GetS3MonitorLogs?StartDate=02/02/08&EndDate=02/05/08
But when I create a SQL XML Webservice via an endpoint all I can find on the net is how to show the wsdl.
http://localhost/Contacts?wsdl
Ive created a method in the "Contacts" webservice called GetContacts. Why cant I construct a similar url to execute that method without having to write a vb.net wrapper for it?

Hi
I have created a SSIS package with an FTP call. I have it set to EncryptSensitiveWithPassword.
I can manually run the package from my IDE. Once I build it, create a job, it fails.
If you try to run the package directly from the Stored Packages in Integrations Services it fails with the following error:
Error: The task "FTP Call" cannot run on this edition of Integration Services. It requires a higher level edition.
This is running on our production with a full version.
Does anyone have any suggestions?ideas?
Any incite would be greatly appreciated.

I would like to call a web service from a sql server 2000 s.proc/sql job, but if there is a better way please let me know. I'm using Captaris Workflow to create and manipulate workflow processes. I have a sql job that will create some pdf's. I want to call the web service that creates a new process in a step from that sql job. I have read about doing this with extended s.procs, but I'm trying to find any possible solutions. Essentially, the web method I want to call will insert several records into sql so I know I can at least do that. I would still like to know if I can make a call to the web service from the sql job. Thanks for any help.

Hello,
I have a microsoft report that uses a dll to calculate a value. If I hard code the value, my report shows it. My method in the dll is connecting to a database in order to calculate a result. However, in order to connect to the database, I am using Microsoft.Practices.EnterpriseLibrary.
The error in my report is:
Could not load file or assembly 'Microsoft.Practices.EnterpriseLibrary.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
I have added a reference in the report to the EnterpriseLibrary but this has not made a difference.
Many thanks!

Hi,
I'm hoping someone has tried something similar before. I am trying to run an integration from a remote computer using a web service. I have set up the web service and the bog standard launch package routine works fine. What i'd like to be able to do is to launch a package and also specify any parameters associated with it. I have the following code which is identcal to the main launch sub with the exception of an extra argument (jagged array of varible name and value variablePair[4][2]). It also processes the variable array and sets them on the DTSPackage object.
[code]
[WebMethod]
public int LaunchSSISPackageWithVariables(string sourceType, string sourceLocation, string packageName, string[][] variableArray)
{
string packagePath;
Package myPackage;
Application integrationServices = new Application();
// Combine path and file name.
packagePath = Path.Combine(sourceLocation, packageName);
switch (sourceType)
{
case "file":
// Package is stored as a file.
// Add extension if not present.
if (String.IsNullOrEmpty(Path.GetExtension(packagePath)))
{
packagePath = String.Concat(packagePath, ".dtsx");
}
if (File.Exists(packagePath))
{
myPackage = integrationServices.LoadPackage(packagePath, null);
}
else
{
throw new ApplicationException("Invalid file location: " + packagePath);
}
break;
case "sql":
// Package is stored in MSDB.
// Combine logical path and package name.
//if (integrationServices.ExistsOnSqlServer(packagePath, ".", String.Empty, String.Empty))
if (integrationServices.ExistsOnSqlServer(packagePath, ".", "executeSSIS", "p4ssw0rd"))
{
//myPackage = integrationServices.LoadFromSqlServer(packageName, "(local)", String.Empty, String.Empty, null);
myPackage = integrationServices.LoadFromSqlServer(packageName, "(local)", "executeSSIS", "p4ssw0rd", null);
}
else
{
throw new ApplicationException("Invalid package name or location: " + packagePath);
}
break;
case "dts":
// Package is managed by SSIS Package Store.
// Default logical paths are File System and MSDB.
if (integrationServices.ExistsOnDtsServer(packagePath, "."))
{
myPackage = integrationServices.LoadFromDtsServer(packagePath, "localhost", null);
}
else
{
throw new ApplicationException("Invalid package name or location: " + packagePath);
}
break;
default:
throw new ApplicationException("Invalid sourceType argument: valid values are 'file', 'sql', and 'dts'.");
}
//Variables var = myPackage.Variables;
//foreach (string key in variablePairs.Keys)
//{
// var[key].Value = variablePairs[key].ToString();
//}
Variables var = myPackage.Variables;
for (int i = 0; i < variableArray.Length; i++)
{
var[variableArray[0]].Value = variableArray[1].ToString();
}
return (Int32)myPackage.Execute();
}
[/code]
For some reason the above code runs and passes back the value that it succeeded. Yet the package doesn't do what it should. Does anyone have any ideas as to why this might be the case or even a better way to pass the variables.
Many thanks,
Grant

I currently have the fllowing Stored Procedure. When I pass the the Url of the web service in the parameters, I'm having a sp_OAMethor read response failed error.
I don't know how to pass the parameter as well as the name of the function in the Web Service I'm calling. Maybe I'm all wrong here with this code too?
Thanks for any help.

We have a requirement to call a Web Service method from SSIS where the method accepts a single parameter that is derived from a database recordset and can exceed 4k characters. From the little we know about the Web Service task it is limited to only accepting direct input and variables. Does anyone have any suggestions to overcoming this issue? Any detailed information in possibly calling the Web Service from script or using an object variable would be extremely appreciated.
Thank you in advance for your help.

Hi Remus,
I just started looking into SB about a week ago, so my question is likely to be pretty lame. However, that's not going to stop me from asking it :-)
We're trying to do something similar to what you're describing here. How do you "reset" a dialog timer? Why would you need to deal with resetting timers (or with timers at all for that matter) in the event of a success? Couldn't you rewrite the logic to be as follows?
begin transaction
receive message
if message is web request
save state of request (http address, caller etc)
else if message is retry timer message
load state of request
endif
commit
do the web request (no transaction open)
if success
begin transaction
send back response
end conversation
commit
else
set a retry timer on the dialog (say 1 minute) using BEGIN DIALOG TIMER
endif
Also, when you set the retry timer you have to associate it with the saved request state, right? Otherwise, how will the service know which request to load on receipt of the timer message?
TIA.

Hello ,
I get this error (connection closed) in web applications, whenever SQL Server database Service is restarted. When I run the application again, the error disappears. Granted that there are lots of users and Database gets restarted every night is not helping.
Is there any setting in the JDBC driver properties, where I can tell it to open a closed connection (like a retry count), rather than fail the first time and work the second time.
We use
1. SQL SERVER 2005 SP2,
2. Websphere Protal Server 5.1
3. SQL SERVER 2005 JDBC driver 1.1(com.microsoft.sqlserver.jdbc.SQLServerConnectionPoolDataSource.)
I am wondering if connection pool driver is causing this problem. I do not care about connection pooling, but Websphere doen not seem to like any other JDBC Driver. I don't mind switching to another driver as the last option.
Error is :
[11/27/07 17:01:59:331 MST] 7202440d WSRdbManagedC W DSRA0080E: An exception was received by the Data Store Adapter. See original exception message: com.microsoft.sqlserver.jdbc.SQLServerException: The connection is closed.

Dear fellow developers,
I have successfully developed a Transact-SQL stored procedure which calls a CLR function, which calls a web service. I am using a Visual Studio 2005 SQL Server Project to perform the necessary magic.
Is there a neat way to deploy this stuff to a production server?
It is bad enough deploying the sp and function, but the web server proxy also needs to be changed to refer to the production web service.
This all looks very nasty and complicated.
Am I missing something?

I would like to build a C# program to connect to a remote SQL2005 server.
Then call the server SSIS to run a .exe in the server (The .exe file already exist in the SQL2005 server)
I have refer to the following webpage http://www.codeproject.com/useritems/CallSSISFromCSharp.asp
I can connect to the SQL server by the "LoadFromSqlServer" method with SQL server login A/C.
However, the SSIS failed. I believe it should be due to the window authentication issue. During SSIS execution, the SQL server login A/C does not have the access right to run the .exe file
Could anyone suggest the solution?
Thanks.

I am trying to cleanly shutdown a dataflow task, which contains a script component, when RunningPackage.Stop() is called from the SSIS runtime.
I've been going in ever decreasing circles with no success - it looks like the cleanest way to find out whether RunningPackage.Stop() has been called is to call FireQueryCancel(). But I can't find any reference to anything useful in a dataflow task script component that gives me something that implements IDTSComponentEvents. The nearest thing seems to be Me.ComponentMetaData which gives a reference to IDTSComponentMetaData90, but this only has methods for calling FireError, FireInformation, FireProgress, FireWarning, and FireCustomEvent. But no FireQueryCancel.
Is there a way in a script component that I can find out the state of QueryCancel?
Any help would be apprecieated.

I'm having a hard time to getting back an xml data back from a stored procedure executed by an Execute SQL task.
I'm passing in an XML data as a parameter and getting back resulting XML data as a parameter. The Execute SQL task is using ADO connection to do this job. The two parameters(in/out) are type of "string" and mapped as string.
When I execute the task, I get the following error message.
[Execute SQL Task] Error: Executing the query "dbo.PromissorPLEDataUpload" failed with the following error: "The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 2 ("@LogXML"): Data type 0xE7 has an invalid data length or metadata length.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
I also tried mapping the parameter as XML type, but that didn't work either.
If anyone knows what's going on or how to fix this problem please let me know. All I want to do is save returning XML data in the parameter to a local package variable.
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

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.

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

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?
