Weblogic: 6.1SP4 Supports Console Extensions

Never seen any docs related to this but weblogic6.1sp4 supports console extensions. Follow the instructions as per 7.0 docs. But here is the trick though, your java class that extends weblogic.management.console.extensibility.Extension should not implement weblogic.management.console.extensibility.NavTreeExtension. Note that NavTreeExtension exists in 7.0 but not in 6.1sp4.
