In Lucee you really do not need JavaLoader, you can specify the path to the jar file as the 3rd argument of
createObject("java", className, path)
But OSGi bundles do not suffer from the issue described by @John_Farrar in the WebSocket installer. The issue there is with a regular jar that must be in the classpath (issue is resolved for the next version of Tomcat). OSGi bundles should deploy properly.
