I have gotten several exceptions while creating and editing a JSF application in MyEclipse 5.1.0 GA. The first ones occurred when accessing faces-config.xml:

java.lang.NoClassDefFoundError: org/eclipse/jst/jsf/core/internal/provisional/jsfappconfig/JSFAppConfigUtils

Others include Linkage errors:

Finally, when attempting to edit a generated JSP, I get the following:

My guess is that you’re going to tell me to download and install the All-in-One installation package. Correct? If so, do I need to uninstall both MyEclipse AND Eclipse 3.2?

[Tom Fulton]

I tried uninstalling MyEclipse and reinstalling with the All-in-One installation package, without removing Eclipse (I still need to use Eclipse by itself for certain things). The JSP issue was resolved by this, and I am just assuming that the other issues are resolved as well.

Does anyone know why this occurs? I mean, it seems to be that there is a clear distinction between Eclipse 3.2 and its associated jars, specifically regarding J2EE apps, and MyEclipse. I wouldn’t expect Eclipse to know anything about JSF, therefore all the JSF jars should exist in the MyEclipse distribution, unless I’m missing something.

TomFulton1953,

You probably have different incompatible versions of EMF.
