MyEclipse version 4.1.1 GA
Eclipse version 3.1.1
Running on window XP.

I got the following error when I tried to open a JSP
page using the JSP editor. It worked before and I am
not aware of any changes on my eclipse environment.
After I got this message. I start my eclipse with -clean flag,
but it can’t help me. It is still not able to open my JSP page. Is
some one have any idea to make it work?

“Unable to create this part due to an internal error.
Reason for the failure: An unexpected exception was
thrown.”

Hi lizhap,
Can you switch to a brand new workspace and create a project and try opening the JSP from there and see if it works ?

[lizhap]

I did it. But it is still can’t open my JSP page

Hi lizhap,
In that case I suggest you download the 5.5.1 “All In One” installer and try setting up MyEclipse using that. That should help you get rid of the NPE.
