Larry, Thanks for the quick response. That was very helpful. I'll take a closer look at that XML file.
I took a look at the Javadoc for both the PlugInContext and the WorkbenchContext classes. It appears as though the WorkbenchContext allows access to the main elements of OpenJUMP's GUI, while the PlugInContext provides access to some of additional objects. I'm betting the PlugInContext simple calls a lot of the methods of the WorkbenchContext class from within its own methods. Do I understand the distinction you are trying to make between the two classes correctly?
