Hi all,

I perform a JSF – Tutorial.
When I try to open the faces-config.xml get an error message with the following stack trace:

!ENTRY org.eclipse.ui.workbench 4 2 2005-08-12 13:34:02.619
!MESSAGE Problems occurred when invoking code from plug-in: “org.eclipse.ui.workbench”.

My versions are : Eclipse 3.1.0, Java 1.5.0_04, MyEclipse 4.0 M2

After browsing this forum I guess that my software versions are not compatible but I’m not sure.

May be I did mistakes.
Thanks for your support.
Best regards.

What is your Eclipse Build ID (Help > About), and your MyEclipse full Version (Window > Prefs > MyEclipse)

[tritzmann]

The eclipse build-id is I20050401-1645, the MyEclipse full Version is 20050627-4.0-Milestone-2.

Many thanks.

The eclipse build-id is I20050401-1645

That’s the problem. Old Eclipse milestones aren’t supported because the APIs weren’t stable. You’ll need to install the final production release of Eclipse 3.1. And, while you’re at it, grab a new copy of MyEclipse 4.0M3 that we just released since it contains hundreds of enhancements and fixes since 4.0M2. The New & Noteworthy is available here: http://www.myeclipseide.com/ContentExpress-display-ceid-66.html

Ok, you confirmed my worries.

Thanks and I ‘ll do it.
