I am getting this error when I call a java method from inside xquery script. I am using basex 7.8.2

Java constructor initialization (aBlob:new) went fine. Even I can call close method w/o any issue.

but when I call insertImage3 in xquery script, I am getting error

[FORG0006] Unknown method

I compiled the class into jar file and put it into libs folder of basex installation folder. I am using basexgui.bat to open basex gui that will load all jars in libs folder.

Is there anything I could not see here?

I appreciate your help
