Hi,
I'm not sure if this is a bug or configuration, but it only started happening after I installed ME 7.0M2. All was fine for a while, then I started getting an error every time I click on any file in the package explorer:
An error has occurred. See log for more details.
java.lang.NoClassDefFound Error
com/genuitec/eclipse/j2eedt/core/J2EEProjectUtil
It doesn't seem to have any real effect - I can still open files, edit, deploy etc.
I uninstalled 5.1GA and 7.0M1. The error then disappeared for a couple of days and I put it down to some sort of conflict (I know there shouldn't be, but ...).
The error has now returned.
I can't locate the log file it is referring to.
I'm pasting my installation summary below:

Hi again.
No - I hadn't tried that - I have now though but it did not help - I'm still having problems.
I have some more details about the issue.
Sometimes, the first error I get is:
'Initialising Java Tooling' has encountered a problem.
An internal error occurred during 'Initialising Java Tooling.
assertion failed: Path for IClassPathEntry must be absolute: MYECLIPSE_LIB_HOME/1.4/activation/jar
This occurs when I first start eclipse.
Sometimes I don't get that message, I get this one instead:
'Building Workspace' has encountered a problem
Errors during Build
Error instantiating builder 'com.genuitec.eclipse.j2eedt.core.WebClassBuilder'.
Plug-in com.genuitec.eclipse.j2eedt.core was unable to load class com.genuitec.eclipse.j2eedt.core.builder.WebClasspathBuilder
Thereafter, every time I select any file in the Package Explorer, I get the error listed in my first post.
Finally, all ths only happens when I start eclipse after a reboot.
When I close down eclipse and reopen it, I get no errors at all ! ! !
Regards,
Aidan. |

Aidan,
Can you switch to a new workspace (File > Switch Workspace > Temp) and check if the problem persists? I get the feeling this is a workspace related issue. |

Hi,
Yes - the new worksace is not generating any errors.
I believe you are right - it's a issue in my workspace.
Now - what's the best way to import projects into my new workspace from the old one without hopefuloly picking up the same issue again?
Can you advise?
Thanks,
Aidan. |

Aidan,
You can switch to the new workspace and go to File > Import > General > Existing Project Into Workspace to import the projects into your new workspace. This should pick up the project without issues. |
