[resolved] ClassNotFound Exception in Runtime

Anonymous — Sat, 16 Nov 2024 10:42:24 GMT

Hi,

I am using tInitLog4J/tLog4jRow components in my jobs which I got from Exchange, it works fine under TOS 6.1, however it throws out ClassNotFound exception as below when I call my routes in Runtime. How to resolve this issue?

Hi,
Did you export your job as osgi bundle jar file or export ("build route") the route to the kar file?
[font=Verdana, Helvetica, Arial, sans-serif] It seems there is a missing jar for [/font] log4j custom components( log4j-X.X.XX.jar ) when you call your routes in Runtime.
Could you please give us more information about your operation?
Best regards
Sabrina

I have the same issue.
Do you find a solution?

PAX Logging used as logging frontend in Runtime and provides limited API for Log4j; to have all required classes in classpath log4j jar should be embded into the job bundle ATM.

I have to use tLiberaryLoad to embed log4j jar for my jobs. After that, it runs fine in Runtime.

I use a similar solution.

Is it possible to configure pom file to embded jar?

Even you config jar in pom, you still need to use tLiberaryLoad...I don't know why, but it is the behavior i am experiencing.
