I have have gone as far as reinstalling xcode and still none of my projects will run. Any other ideas? I am running on xcode 2.2 w/component versions
Xcode IDE: 655.0
Xcode Core: 658.0
ToolSupport: 651.0


All permissions seem to be correct, files are all there, and the only thing that had changed since the last time the projects ran was that I had run Software Updater and it installed 3 new updates, don't remember what they were but could that even make any difference?

thanks
ian

That seems to suggest that /System/Library/Frameworks/ JavaWebObjects.framework/Resources/Java/javawebobjects.jar is not on the classpath or can't be read (due to lack of permisssions). Is JavaWebObjects included in the frameworks? Do you see it on the classpath when the app launches?

You really need to check the whole tool chain.

When things go to heck in a handbasket, you need to check all your assumptions. Remember, any time you "ASSUME", you make a you-know- what out of you and Uma Thurman....

1) What jars do you think you are using? (Seems you have a handle on that.)

2) Are those the right jar files? If you look in the file system, do those jar files actually exist? Can you read them? Do they actually contain the classes you expect? You can do check with such as:

% jar tf /System/Library/Frameworks/JavaWebObjects.framework/ Resources/Java/javawebobjects.jar

If you are able to do this and you see the class "com/webobjects/ appserver/WOApplication.class", then that is covered.

3) Are you actually using the right jar? Look in the MacOSClassPath.txt file. This is probably ok, given the output that you see from the application, but it is good to check.

4) If you invoke the application manually, constructing the classpath that you think is needed, does it work any different?

It is theoretically possible that one of the other things I see on your classpath, being things I do not really recognize, may be doing something to set your default class loader or change the behavior of the default class loader. That would be "a bad thing".

Sometimes one just to follow all the dots.

One of my favorite random things is this. Have you put this on a UFS file system? Taking something off a case-insensitive file system like HFS+ and moving it onto a case-sensitive file system like UFS can lead to hours of fun for the whole family.

Good luck.

ps: Always good to have in these posts: OS version, Dev Tools versions, any other random things you install....

I can not figure out how to fix this problem, mainly because I don't know how I did it. None of my WO projects will run any more, they all exit with status 1. Even if I just create a D2W, it still exits with status 1. They all have this in the Run Log:
