I browsed already the forum and tried to follow what was described as a possible solution.
In my plugin I am using a library (jar lib). I placed the library in the lib folder of my plugin source. Compilation of the plugin is successful and I also can execute the library. But when I am running the code where the library is used I am getting a
java.lang.NoClassDefFoundError: Could not initialize class …
I followed the advice in copying the lib to the folder
but I am still getting the same error.
I am using the latest released Openfire version.
Thanks in advance for your help!
