Hello Gaurav,
First off, not sure why you are calling
call.addNamedArgument("JOB_ID", "JOB_ID_I");
call.addNamedArgumentValue("JOB_ID", jobId);
You should call the first statement to indicate you will be adding in a "JOB_ID_I" argument to the query, or the second statement to add the value directly to the call, but not both. Calling both indicates your procedure is expecting two parameters called "JOB_ID" and you will get an exception if you do not define the "JOB_ID_I" argument on the query and pass in a parameter for it.
TopLink does not currently create Oracle objects such as Structs and VARRAYs for you from java objects - atleast not for stored procedures arguments, as it does not know how or what to convert them to. You will need to create the Oracle object type yourself, and pass it into the query. I have not tested it, but it would look something like:
UnitOfWork unitOfWork = getUnitOfWork();
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName("DSM_JOB_PKG.INSERT_JOB_RUN_LOG");
String jobId = jobIdItr.next().toString();
call.addNamedArgumentValue("JOB_ID_I", jobId);
Timestamp sysdate = BeanConvertUtil.getCurrentTimestamp();
call.addNamedArgumentValue("ORDER_DATE_I", sysdate);
call.addNamedArgumentValue("USER_ID_I", userId);
Connection con = getSession().getAccessor().getConnection();
oracle.sql.ArrayDescriptor anArrayDescriptor = new oracle.sql.ArrayDescriptor("GENERIC_STRING_TYPE",con);
oracle.sql.ARRAY anARRAYin = new ARRAY(anArrayDescriptor, con, paramTypeIds );
call.addNamedArgumentValue("JOB_PARAM_TYPE_IDS_I", anARRAYin );
oracle.sql.ARRAY anARRAYin2 = new ARRAY(anArrayDescriptor, con, paramValues);
call.addNamedArgumentValue("JOB_PARAM_VALUES_I", anARRAYin2 );
session.executeSelectingCall(call);
