Ok, now I got it. First, I suggest you to got source code from subversion - https://svn.netxms.org/public/netxms/trunk. All Java sources located under src/java. Console is written on Eclipse platform, so plugin development is just a normal Eclipse plugin development process, which is well documented on Eclipse web site - www.eclipse.org. If you have questions, ask them on forum in development section.
Best regards,
Victor
