Work Manager 6.2 Customization's on SMP 3.0

Hi Experts,

We have deployed the Work Manager application to SMP 3.0.We have done customization's in Agentry front end,Java,ABAP. Done the necessary modifications in Agentry.ini file,added the custom jar file in java folder,published the front end application to server,mapped all custom handlers,filters java classes in configpanel.When we have tried to sync the custom application, encountered the "Communication error".Checked the server logs and found COM.SYCLO.AGENTRY.BUSINESSLOGICEXCEPTION: INVALID CREDENTIALS | .Event logs contain the error "Error in updating service. Exception: NameSpace can not be left empty |".

Please suggest how to proceed further.Thanks in advance.

Thanks & Regards,
