Hi,
I'm having this problem since I tried to deploy and run an ESS application for testing. here are the details of problem.
An internal error has occured. See error log for more details.
Plugin name: Metamodel Core
Plugin ID: com.sap.ide.metamodel.core
Class: com.sap.ide.metamodel.core.plugin.MetamodelManager
Method: getJavaProjectClassPaths
Message: project has no Java Nature. projectName = GDI_XSS11dev_Dessgbaddrsap.com
Exception: org.eclipse.core.internal.resources.ResourceException: Missing project nature class for org.eclipse.jdt.core.javanature.
Same problem is being reported for every DC in NWDS Web Dynpro perspective and perspective is not loading correctly. I changed the workspace and perspective came back fine - with no DCs of course.
I'm using NWDS 7.0.20 and j2re1.4.2_14.
Could you help me solve this problem?
Regards,
Vishwas.
