Hello,

 

I followed this official tibco guide, to create an xpath custom function, this makes use of an external java library, so i added these external library as shown by this other guideadding-a-jar-to-a-bw6-plugin-project

At designtime the applicationworks perfectly, at runtime after call custom function goes into error:

kubectl logs -f testplugin-dc565f544-9bqxm | grep CausedBy
