JDBC with DB2/400 - Error when calling external routines


Hi All:

I am using JDBC to connect to DB2/400 to call a Stored Procedure. Here is my AS400 code that works fine with no problems.

CREATE PROCEDURE  IJLIB/WEE1520IJ
(IN giftc# CHAR (19),            
 IN sbalal CHAR (11),            
 IN caltyp CHAR (2),            
 IN rspky CHAR (10),            
 IN wtime CHAR (3),              
 OUT DTA213 CHAR (213))          
 LANGUAGE SQL                    
 Modifies SQL DATA              
 NOT DETERMINISTIC              
                                 
 BEGIN                          
 set DTA213 = 'ABC';            
 END;

Now my actual requirement is to be able to call an external routine. So I made a few changes to the above code in that I removed the BEGIN..END block, changed LANGUAGE SQL to LANGUAGE RPGLE, and added the clause EXTERNAL NAME WER1520IJ, as shown below:

CREATE PROCEDURE  IJLIB/WEE1520IJ
(IN giftc# CHAR (19),            
 IN sbalal CHAR (11),            
 IN caltyp CHAR (2),            
 IN rspky CHAR (10),            
 IN wtime CHAR (3),              
 OUT DTA213 CHAR (213))          
 LANGUAGE RPGLE                    
 Modifies SQL DATA              
 NOT DETERMINISTIC  
 EXTERNAL NAME WER1520IJ
 Parameter Style SQL;

Now when I run my Java program I get the following error:

  Error in SP call: java.sql.SQLException: [SQL0440] Routine WEE1520 in RELIB not found with specified parameters.
  java.sql.SQLException: [SQL0440] Routine WEE1520 in RELIB not found with specified parameters.

        at com.ibm.as400.access.AS400JDBCConnection.prepareCall(AS400JDBCConnection.java:1483)
        at callCommand2.main(callCommand2.java:82)

Does anyone have an idea what I might be missing?  I have added the libraries to my JDBC connection specification when opening it.

Thanks - Inayat

You have put your stored procedure in IJLIB, but the JDBC connection's default library (the current library..) is RELIB.
You should indicate to JDBC that you want to use a library list rather than the current library,
or use a qualified procedure like
call  IJLIB.WEE1520IJ (....)

Hi ShalomC:

Thanks for your response.

I am sorry for the confusion. Please ignore the error message I showed above. I messed up with the procedure that I actually called with the corresponding error message that I copied and pasted. Let me start afresh.

My AS400 Stored Procedure looks like this:

CREATE PROCEDURE IJLIB/PSE1210
(IN giftc# CHAR (19),          
 IN sbalal CHAR (11),          
 IN caltyp CHAR (2 ),          
 IN rspky CHAR (10 ),          
 IN wtime CHAR (3 ),          
 OUT DTA213 CHAR (213 ))      
LANGUAGE CL                    
NOT DETERMINISTIC              
MODIFIES SQL DATA              
EXTERNAL NAME ijlib/psc1210    
PARAMETER STYLE SQL;          

Here is the error message:

Error in SP call: java.sql.SQLException: [SQL0440] Routine PSC1210 in IJLIB not found with specified parameters.
java.sql.SQLException: [SQL0440] Routine PSC1210 in IJLIB not found with specified parameters.
        at com.ibm.as400.access.JDError.throwSQLException(JDError.java:594)
        at com.ibm.as400.access.JDError.throwSQLException(JDError.java:565)
        at com.ibm.as400.access.AS400JDBCStatement.commonExecute(AS400JDBCStatement.java:742)
        at com.ibm.as400.access.AS400JDBCPreparedStatement.execute(AS400JDBCPreparedStatement.java:744)
        at callCommand2.main(callCommand2.java:154)

Ofcourse I do have the routine PSC1210 in IJLIB. I was able to call PSE1210 directly from AS400 itself, and it worked fine. But when I want to do the same using JDBC, it fails with the above error message. I now have both the stored procedure and the external routine in the same library - IJLIB.

My JDBC connection string looks like this:

connection = DriverManager.getConnection("jdbc:as400://10.2.23.9/;libraries=IJLIB","TESTER","TESTER");

Please let me know if you have any suggestions.

Thanks - Inayat

Inayat,
Did you try to call the stored procedure from the AS400 itself? Please tell me what are the results of such a call.
Either use interactive SQL or write RPG program to call the stored procedure.
Start a debug session before the call, so a detailed job log will be produced.

I have a feeling that you have a parameter mismatch between the CL, the stored procedure declaration, or the actual call.

Since I'm no JDBC expert by any means, I'm only guessing here; but you _might_ want to make some changes in your parameter definitions. For example:

 IN rspky CHAR (10 )

might be better specified as

 IN rspky VARCHAR (10 )

Seems surprising that Java wouldn't be trying to send VARCHAR parms. Of course, appropriate changes should be made to your stored procedure as well.
