Data Deploy external-tuple-processor class is not loading

Hello there,

I am working on the migration of the old workflows to new workflow modeler. I am facing a problem in loading the class for TPP which is used in DD config.

Old TS version == 6.5

Old OD version == 6.2

New TS version == 7.4.1

New OD version == 7.4.1

I have recomplied the java file (which is called for TPP ) on JDK 6 environment and placed the .class file it under ODHOME/userlib and restarted the OD. When I execute the DD from command line, the logs says it failed to load the class file. class file is not in any package so I have directly put the name of class file.

I have tried to put the class file in a jar and placed it in ODHOME/userlib and restarted OD but it still throws error.

DBD: Attempting to load class: custom_class_name
DBD: ERROR:Unable to load class custom_class_name:Class Not found

Thanks

Rajesh

It worked now.

It is not accepting the class file from ODHOME/userlib which it used to accept in OD version 6.2.1. My previous jar which I exported from my IDE was may be corrupt (I am just guessing) or don't know th real root cause as it didn't work (DD couldn't load class file even after multiple restarts.) . I put some debug statements andwhen I exported a fresh jar with required class file. Placed under ODHOME/userlib and restarted OD it worked.

Thanks

FWIW - I believe the class gets compiled into the jar file and OD/DD loads the jar file - not the class file - so that's probably why it didn't work until you recompiled your jar file...

Hi Adam,

I think you are right but the prior version (6.5) was able to load the class file but not the latest version (7.4.1). It is only loading jar files. 6.5 version which is still running, there is only class file which I see under ODHOME/userlib and DD works fine.

It seems it's the different versions where OD/DD handles the class or jar file loading differently.

Thanks
