I tried to open a jsp file and the editor failed to open. Logs pointed to a NullPointer exception. Include the stack trace. Any thoughts?

Hi,

Can you please answer below queries -
1. What is your installation detail? Open MyEclipse IDE, from menu options click on MyEclipse > Installation Summary > installation details
2. What is the editor you are using to open the JSF file? Can you check if you are able to open the jsp file using a different editor
3. Have you added any third party plugins? If yes, can you list them here?

Can you refer to http://www.myeclipseide.com/PNphpBB2-viewtopic-t-24926-postdays-0-postorder-asc-start-0.html and check if the solutions work for you

Thanks

I downloaded 8.6 of MyEclipse and the problem seems to have gone away, great news. During the install, I tried to upgrade my current version of MyEclipse, but the installer reported missing components, so I had to place a copy of 8.6. Somehow, I thought the installer would have all the necessary components to perform an upgrade. I must be missing something here. In the future, I would like to just upgrade rather than copying new versions to preserve disk space. I do a bit more research on just how to perform an upgrade.

Thanks so Much

dcdantzler,

Good to hear you are all set.

Best.
