One or more constraints have not been satisfied. Cannot install project facet Java 1.6.

Even i am facing the same problem... I am using JBoss AS with GateIn. Now for developing portlets, I tried installing JBoss Tools in Eclipse Helios, but all my efforts in vein. Please find the errors below and please help me asap. 1)Using update site - ‘cannot connect to the repository’ 2)Offline installation using zip file - ‘operation cannot be completed, missing dependency’ 3)Add a link file in the dropins folder in eclipse - Didn’t recognize JBoss portlet After doing these, I am not able to view portlet facets. 4)Copy paste all features and plugin from JBoss Tools zip to eclipse features and plugins. •This is the last option that I tried. After this I am able to create a web project with portlet facets, but getting an error as mentioned here. I got a solution from JBoss Tools saying that adding seam feature will solve this as this is a dependency for portlet. Since I copy pasted all features and plugins, I think that seam should also be installed. So please help me in resolving this.
JBoss IDE is not a webtools component. Please address these issues on that product's support forum. If you believe there is an issue in webtools itself, please document this issue with repro steps.
