I have updated my development tools to Eclipse 3.1 + MyEclipse 4.0M2 in Windows XP enviroment with:

java version “1.5.0”
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode)

When I try to open struts-config.xml i get this stack trace:

java.lang.NullPointerException

The only way to open the file is use: Open With –> MyEclipse XML editor.
Note that with the old version of MyEclipse, with eclipse M7, its all Ok.

Thanks.

Gianni,

Do you have a clean install of ME 4 and E3.1 or did you upgrade?
I know we had a problem with a similar stack trace, but it was fixed before the build (or so I thought).

The StrutsProject properties (right click on project >properties > Struts) has a setting which allows you to disable the designer, can you disable it and see if it works for you? If it does, enable the designer and try again.

Is the designer working for other struts configs and not working for only this one? Or is it failing for all config files?

Best,
Brian.
