You also have to make sure that you have your plugin properties file  
set up correctly.

This is especially the case where your code depends on other plugins,  
such as OWL:

See the section "Dependencies on other plugins" at (<http://protege.stanford.edu/doc/pdk/plugins/plugin_support_21.html 
 >) for details.  Note that this particular information is not all  
that easy to locate, especially since the change that is needed  
happened a while ago, so it might not be immediately obvious that you  
need to read the 2.1 documentation to develop plug-ins for version 3.x

I know that resources are a bit tight at Stanford, but it would be  
good if this dependency information and a short description of the  
plugin properties file could be added more prominently, probably as  
part of the existing item "Learn how to create a plug-in manifest and  
JAR (information about packaging a plug-in as a JAR file)."
