Hi,

I am evaluating the myEclipse product for use in our corporate. I tried to deploy a sample Struts application with the trial version downloaded from your site. I tried to open the struts config file of the application with struts config editor provided by myEclipse. It throws null pointer exception as follows. It would be very much helpful if you can help solve this problem, so that I can evaluate the capabilities for purchasing the license.

Gayatri,
We are sorry you ran into this problem. First to tell if the installation is correct, can you go to MyEclipse > Installation Summary > Installation Details and paste the result here for me? That will help me tell if the installation needs repair or if the problem lies elsewhere.

Your setup looks OK, can you look at your log file (<workspace dir>\.metadata\.log) near the end, for exceptions that may shed some light on what is going on? Also have you added Struts capabilities to this project so MyEclipse understands it as a struts project properly?

[gayatri.venkataraman]

Riyad,

I have pasted the exception from the log file from the location you have specified. It looks like the log file exception and the one I have posted is identical

And there is no more information *after* that spot? What happens when you create a new web project, add Struts capabilities to it, and open the struts-config.xml file? What happens whe you walk line-by-line through our Struts tutorial, does that work?

The key here is Struts capabilities, if you try and open a struts-config.xml file without struts caps on your project you should be notified that it cannot be opened with the special Struts editor, but instead will be opened with the XML editor.
