Executing stored procedure via java

Question

Hi all,
i have a problem calling a stored procedure in my java code. I found an example at OTN which seems not to be correct. i had the following VB-code to translate to java:
Set k = Server.CreateObject("ADODB.command")
With k
.activeconnection = Db
.CommandType = 4
.CommandText = "Get_SK"
Set vret = .createparameter("vRet", 131, 2) 'Output
.Parameters.append vret
.Execute
End With
In my java code:
CallableStatement sproc_stmt = null;
try {
sproc_stmt = lsession.connection().prepareCall("{ ? = call TCSDBOWNER.Get_SK}");
sproc_stmt.registerOutParameter(1,OracleTypes.NUMERIC);
sproc_stmt.setFetchSize(10);
sproc_stmt.execute();
The call generates an id for inserting new rows in the DB. executing the code shown above i got the following error:
wrong number or types of parameter/arguments
Is there anybody who can help me? Best regards,
ak

Hi,
thanks for your reply.
I have the description of this procedure (As you can see in my posting above) So it is definetly a procedure with one input parameter.
Yes ist it a callable statement as the other one before. So the first one:
CallableStatement sproc_stmt = lsession.connection().prepareCall("{call Get_SK(?)}");
               sproc_stmt.registerOutParameter(1,Types.NUMERIC,1);
ResultSet sproc_result = sproc_stmt.executeQuery();
Works fine. No more problems with that. It is a procedure with one OUT_PARAMETER and no INPUT_PARAMETER.
So, the only thing to change (I thought is):
sproc_stmt = lsession.connection().prepareCall("{ call Get_SKS(?,?)}");
               sproc_stmt.setInt(2,1);
               sproc_stmt.registerOutParameter(1,OracleTypes.NUMERIC);
ResultSet sproc_result = sproc_stmt.executeQuery();
But this seems not that obvious. I got an error:
java.sql.SQLException: ORA-01722: invalid number
ORA-06512: at "SYS.DBMS_SYS_SQL", line 826
ORA-06512: at "SYS.DBMS_SQL", line 39
ORA-06512: at "TCSDBOWNER.GET_SKS", line 44
ORA-06512: at line 1
So it seems something is wrong with this output parameter!?
Any more help? Regards,
