    – System Setup ——————————-
    Operating System and version: Windows XP, 5.1
    Eclipse version: 2.1.2
    Eclipse build id: 200311030802
    Fresh Eclipse install (y/n): Yes
    If not, was it upgraded to its current version using the update manager?
    Other installed external plugins:
    Number of plugins in the <eclipse>/plugins directory that begin with org.eclipse.pde.*:
    MyEclipse version: 2.7
    Eclipse JDK version: 1.4.1_05
    Application Server JDK version:
    Are there any exceptions in the Eclipse log file?

    – Message Body ——————————-

    I can no longer view the Workbench properties. When I click Window->Preferences, the spot where workbench should be displayed is empty. After I do Windows->Preferences one, I can no longer perform that operation without first closing Eclipse.

    Additionally, I can not right-click on a EJB project for example and add files to the buld path.

    Plus when I can no longer view the Help files I receive the message: The embedded application server could not run help web application.

    These are just a few problems I’m having. Fortunately I can still build and deploy my EAR, but I now need to add a jar reference and can not.

    Thanks!
    Mark

    Mark,
    Things sounds like they are falling apart on you… lets see if we can fix you up. Can you go to Help > About > Configuration Details and paste the result into a giant message for us? This will give us ALL the details about your setup and any log messages.

    If the log is rediculously long, then try and chop it and leave the last 2 or 3 entries starting with “!SESSION———“, those markers denote every time you fire up Eclipse.

    Hi Riyad,

    Yes, you guessed it, my log file is rather large. Here is the last part:

    Hmm… try closing down Eclipse, and then moving (or erasing) the <workspace dir>\configuration and <workspace dir>\.metadata\.config directories. (NOTE: You may/maynot have a ‘configuration’ directory, I’m going from memory here).

    Now restart Eclipse, it will rebuild its state cache, hopefully fixing any issues. The not being able to start the internal app server for the help system is common and not necessarily indicative of the world ending, it just bothers me that you are missing your workbench settings… those are kind of important 😀

    I removed the workspace\.metadata\.config directory but was unable to start Eclipse after I did this.

    I received an error msg that stated: “Problems during startup. Check the ‘.log’ file in the ‘.metadata’ directory of your workspace. The log is as follows:

    mbrehm,
    I thikn there is something *very* wrong going on here. You might look into a clean reinstall and recreating your work space. Deleting the .config directory clears out the workspace cache, and then restarting Eclipse recreates the cache. This was a common problem with the 3.0 M-builds and MyEclipse with previous releases and we never had someone bork their install by removing it (it is just recreated).

    If you don’t want to reinstall clean, then I would suggest moving your workspace directory to your desktop (temporarily) which will cause Eclipse to basically reinstall itself clean. Then you can move your project’s back and reimport them. Its possible that some of the plugin cache data in your workspace is corrupt and is causing all this trouble. Please keep in mind that the 3.0 M-builds are alpha/beta quality and running into problems like this are part of the process of testing non-final builds.

    If you need to have a production quality environment then we highly suggest Eclipse 2.1.3. and ME 2.7.1. Although I realize many users aren’t willing to give up a lot of the nice new features in Eclipse 3.0 😉

    You’ll find in the forums we get a lot of questions about problmes with 3.0, and a clean reinstall always seems to clear things up because there are issues with cache corruption and preferences being lost.

    Thanks Riyad,

    If I try moving the workspace directory, will I need to reinstall MyEclipse?

    Or, if I choose a clean install, do I first install Eclipse over the existing directory and then MyEclipse or should I do this in a new directory.

    Finally, you mention 3.0, but I’m running 2.7. Do your suggestions still hold true?

    Thanks.

    Finally, you mention 3.0,

    Oh geeze, I get so conditioned seeing some of these errors that I just assumed you were running 3.0, I’m sorry.

    Actually given the situation you are in I would still suggest a clean reinstall to a new dir and everything doing the following steps found here:
    http://www.myeclipseide.com/FAQ+index-myfaq-yes-id_cat-4.html#156

    Or, if I choose a clean install, do I first install Eclipse over the existing directory and then MyEclipse or should I do this in a new directory.

    No you don’t install anything ‘ontop’ of itself, you really have to clear everything out, exporting any savings you want, and then reinstall and import settings and old projects. Please follow the FAQ verbatim to safely do a reinstall. You need to be careful with maintaing your workspace long enough to move your old projects out of it and reimport them from their new location.

    If you have questions/worries please ask.

    I’m going to close this thread and keep my fingers crossed, if you into any issues I’ll reopen it ASAP.
