Fails to lunch a job ones refactored

Hi everybody,

I am developing a new custom method through Composer, I created :

- Jar definition

- Module

- Java method

- Job

This job was running well until I tried to refactor all my objects {Jar definition file, Module file...}

I got the following error :

ERROR [http-0.0.0.0-9080-1] com.documentum.mthdservlet.DoMethod - Exception attempting to load module

MSG: [DFC_BOF_CANNOT_FIND_OBJECT] Business object does not exist in docbase >; ERRORCODE: ff; NEXT: null                                                 

I tried to remove all My deployed object trough DA and reinstall, but it still don't work.

Does any one knows :

1- How to fix this issue?

2- How to properly uninstall deployed job?

Thanks in advance
