I am new to Java Stored Procedures. There is a PL/SQL package in our legacy application(Oracle 9i) which pulls data from Oracle 8i source database through a DB link. Now we have upgraded our databas to Oracle 11g R2 from 9i. So the DB lint to Oracle 8i will no longer work in 11g. Hence I have created a Java stored procedure that establishes JDBC thin connection to the source 8i database. I have loaded the java stored procedure in the database using loadjava and have created a call specifaction.
I have called this java stored procedure inside the PL/SQL package. Now while executing the PL/SQL package, it takes the default driver ojdbc6.jar to establish JDBC connection and fails to connect to the 8i database giving ArrayIndexOutOfBounds Exception. While running the code in the linux application server with classes12.jar the code succeeds. But when the same is called in the database it fails.
1. How can I make my PL/SQL call use classes12.jar while calling the Java Stored Procedure?
2. How can I load the jar file(which includes my classes and the classes12.jar) into the datase as one object? (When I tried to load the whole jar, in database the classes and dependent jar loaded separately)
3. Is there a way to use classpath while calling the Java Stored Procedure like how we do from Unix?
I'm new to Java. I need to run a SQL server stored procedure(that creates a unique job number) from Oracle SQL Developer (JDBC) in Java. The same Java code will be used in Applescript to run the SP. I found a code snippet online with the similar requirement. How to embed my SP in below code snippet? Below is the Stored Procedure and Code Snippet:
SP
EXEC Int.dbo.GetNewJobNumber '6852', 'Test Job', 'Manual SQL Query' 6852- CustomerCode, Test Job - Job Title, Manual SQL query - Shows how new job number was created.
I have a .csv file ,and I have written a jsp code which uploads csv file to a local folder . Now I want to upload that csv file to database using stored procedure. Below I have included the code which uploads the csv to database.
I have a very complex oracle stored procedure that searches and retrieves some data. The procedure returns an output parameter - an oracle cursor. I execute the procedure by JDBC:
The problem is, the queries can sometimes take quite long (few minutes) and i would like user to be able to cancel the query anytime by clicking button. I have reference to stmt object, but unfortunatelly calling stmt.cancel() (from other thread) has NO EFFECT.
On the other hand when i change the CallableStatement sql to some query like:
CallableStatement stmt = conn.prepareCall("select * from all_objects");
I get "java.sql.SQLTimeoutException: ORA-01013: user requested cancel of current operation" after calling stmt.cancel()
- so thats the right reaction.
Does that mean than i cannot cancel stored procedure call via jdbc, but only simple select statements? I guess i could cancel the query by oracle kill session, but i use connection pooling (jboss) and i have plenty of sessions for the same user existing.
Database Product Version is Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production JDBC Driver Version is 11.2.0.4.0
I am using CachedRowSet returning it from a parameterised select statement and it works fine.
If I put the same select statement into a simple read-only stored procedure then I get this exception: "A result set was generated for update".
I am not trying to update the rowset in my code.
I tried to make the CachedRowSet to be read-only but it does not work, same error.
Question 1 : can a stored procedure returning a single result-set be called to populate a read-only CachedRowSet? (in a similar fashion to a CallableStatement prepareCall method with input/output parameters).
Question 2: in general is using CachedRowSet, WebRowSet, FilteredRowSet (disconnected) and JDBCRowSet (connected) something to be encouraged for future develpment or are they deprecated, or replaced by something else/better??
calling a parameterized stored procedure in java jdbc from sql server.The stored procedure goes like this in sql
create proc patientreg @id int as begin select [patient_id],[Psurname], [pFirstname], [pMiddlename], [reg_date], [DOB], [Sex], [Phone_num], [Addr],[Email],[dbo].[fncomputeage](DOB) from [dbo].[Patient_registration] where [patient_id] = @id end please note dbo.fncompute(DOB) is a function
I know that Servlets are meant to do the JDBC tasks, JSP are only for displaying the final information forwarded by the Servlet.
JSP are Servlets too, but I heard an idea that it is safer to make database operations in a Servlet.
The idea is that I have a few JSP that use JSTL tags to retrieve some database information. By doing this I was concerned that this may be bad design, though I really wanted to get in fit with the JSTL tags.
Are there any security weaknesses if doing some JDBC stuff in a JSP, by using JSTL or plain Java code in <%...%>?
P.S. In my JSP I only retrieve data, not modifying it.
We currently have an application which uses JDBC to connect to the backend database (DB version - 11.2.0.3 ). The application uses a properties file in which the password for the db schema is hardcoded in plain text format. Due to security restrictions we have been asked to make sure the password is encrypted in the file and no direct access is made to the schema using the plain text password. Best options we can use to make this password encrypted both at Oracle DB side and Java side.
I'm using jsf 2 to upload file, first I upload the file in a system directory, then trying to store the path to database with other information, my stuck is that when submitting I upload the file successfully, find it in the right place, find the other information such as description, file name ... in database but don't find the path. this is my managed bean :
I did an application with jframe which i store member personal info like name, surname etc.But when i save it to Mysql database the values are ??????.I have changed database and table and columns collation to utf8, i checked java encoding it's utf-8 but the problem remains.i have spent hours in google search but nothing that works.
We have web based application (Oracle DB, Weblogic middle tier) and a applet based application running on the browser.
We have a requirement to Load images from the database (stored as blob) to the client browser and the users can do the lookup on images when needed.
We need this to perform well, so there is no delay for the user experience. We have 2 options:
1. Load the images from the database to the Application Server and keep it. When the client request from the browser comes, download it from the application server.
2. Load the images (asynchronosly) when the user logs into the application and download them to the Client machine? Is this possible? Especially give that it is stored in the database as binary objects? And then load for the user from the client box itself, upon request.
If 2nd option is possible, which once is recommended?
I need to know the procedure for detecting a Unique Hardware ID of any computer using Java. All I want to do is once the software application is installed should not get installed using the same key...In short I want to do license for my application.
I have a problem about this numeric or value error on my java class. Whenever I am calling for the procedure in callable statement it says that error. I don't know what is the problem with my sql code because I;ve tried running it on database alone and it runs perfectly. The results that I need came out fine. But when I'm already calling it in java that error appears. But I tried on finding the line that the said error is coming from and here is the code...
create or replace PROCEDURE RENTING (P_NNAME IN VARCHAR2, P_ADD IN VARCHAR2, P_PHONE IN NUMBER,
I have been having trouble with a recent hw assignment requiring us to sort user defined data types in an array. so far, i have implemented the sorting algorithms correctly but i cant seem to store a string and an integer together. I have an employee class
[public class employee { private String Name; private int IdNumber; public employee(int IdNumber,String Name){ this.Name=Name; this.IdNumber=IdNumber;}
[Code] .....
And in my app, i create a employee object-----> employee john=new employee(1020, "John");
How can I prompt my insert method to take in employee id and string name together?
I am wondering where the attributes I put into the Httpsession are stored.
For example, if I do the following HttpSession session = request.getSession(); session.setAttribute("usr", usr); session.setAttribute("pwd", pwd);
where does the ("pwd", pwd) pair store?
In my case, my web application needs to use the usr and pwd to login to another application, so I have to store them somewhere. So for security reason, if the pwd is kept in the browser side, I need to encrypt it first before I put it in the session. On the other hand if it is stored in the server memory then encryption seems not necessary
I've created a Dynamic Web Project in Eclipse Kepler EE, connected it to a Tomee plus 1.7.1 server and created a servlet and a POJO. So after opening the browser and trying to do something with the classes, the servlet worked as expected, but the POJO returns error 404.
The actual code is something like this:
// The servlet public class MyServlet extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { PrintWriter out = response.getWriter(); out.println("I'm a servlet.");
[Code] ......
So when I type "localhost:8080/<project_name>/MyServlet" I get the expected "I'm a servlet." message. The problem is with the POJO:
//The POJO @Path("/MyPOJO") public class MyPOJO { @GET public String get() throws IOExeption { return "I'm a POJO."; } }
I have nothing about that class in the web.xml file. I have this class, that I don't really know what it does:
@ApplicationPath("/sth") public class ApplicationConfig extends Application { @Override public Set<Class<?>> getClasses() { return new HashSet<Class<?>>(Arrays.asList(MyPOJO.class)); } } Application is a class from M2_REPOjavaxws sjavax.ws.rs-api2.0.1javax.ws.rs-api-2.0.1.jar
So when I enter "localhost:8080/<project_name>/sth/MyPOJO", I get error 404, no exceptions no logs. I've tried to debug but it doesn't hit any breakpoints.
Maybe it has something to do with the exception I get when I start the server:
Nov 19, 2014 6:44:50 PM org.apache.myfaces.ee6.MyFacesContainerInitializer onStartup INFO: Added FacesServlet with mappings=[/faces/*, *.jsf, *.faces] Nov 19, 2014 6:44:51 PM org.apache.myfaces.config.DefaultFacesConfigurationProvider getStandardFacesConfig INFO: Reading standard config META-INF/standard-faces-config.xml
[code]....
I've tried to add the line that is missing in the server.xml file but then the server doesn't start at all.
When my college tries to run it on his PC, it work with both the POJO and the Servlet. We can't find any reason why it's not running on my PC.
Question 1: Upon importing the Play Framework content in Eclipse there's a default codes as localhost:9000 is immediately routed to play framework website controllers, checked and running fine test, checked and running fine conf, checked and running fine the problem is the views under app on all youtube tutorials and other websites, the contents of views is editable but when my brother tried to, he cant edit it
Question 2: Is there an easy tutorial on POST, PUT, GET, and DELETE for eclipse-playframework
Question 3:my brother is using POSTMAN - RESTCLIENT to test his HTTP METHODS (post, put, get, and delete)and is there a tutorial where they also test the HTTP METHODS using POSTMAN?
I am trying to connect to Sql Server database using Oracle UCP with sqljdbc4-3.0 JDBC driver for Sql Server,with different ports and instances.
– the issue is with the port being ignored in the server string.
For example, using port 1440 connects to the default instance (which is on port 1433) rather than MSSQLINSTANCE1 which is on 1440.
Below are Server hosts used.
sql005.sqlasoftware.com (connects correctly to the default instance) sql005.sqlasoftware.com:1440 (connects incorrectly to the default instance on port 1433) sql005.sqlasoftware.comMSSQLINSTANCE1 (connects correctly to the named instance)
