The java error which i meet in the oracle 11g when i using jdm

Question

I have finish a java data mining program,it can work in oracle 10g.But now ,i  have to apply this program in oracle 11g.
What should i do to make it still work in oracle 11g?
The jar have been replaced with 11g's jar.But when i debug the program,the BuildTask's m_ programName is still "dmsys.build_program" and it should be "sys.build_program".
Then when run to the executeTask,the Error occurred.

247*******************the buildTask's m_programName is “dmsys.build_program” but it should be "sys.build_program" when i contact the 11g.I have tried many ways to compile the program,but it still can't be changed.
