Hello,
I developed a custom Kettle plugin, which defines 3 transformation steps for use in several transformations. I copied the plugin jar and its dependency libraries in <PDI-HOME>/plugins/steps, and if I run the transformation with the custrom transformation step inside the Kettle GUI environment everything goes ok. But I have problems when I try to run the transformation in embedded mode inside of a Java project, I have the next error:
The custom plugin jar is added as a dependency to the project, but seems that the application classloader can't find the annotated classes for the step "OfaiSimpleConverter".
I found that if I copy the custom plugin jar and its dependencies inside the folder <USER-HOME>/.kettle/plugins then the project runs ok, but this is not a valid solution for me (the intention is to run the project as a library inside a Java EE application server).
Any ideas of how to manage the classloading of custom plugins jars by code?
Thanks in advance.
P.S.: I'm using the version 5.1.0.0-752
