Hi list,

We have a problem with the classpath in MyEclipse Blue Edition, when working on a Portal Project (JSR168). I don’t yet know if the problem appears also in MyEclipse.

This is the necessary scenario to reproduce the problem:
1. Open the portal project in a Workspace (we could call it A) in MyEclipse Blue.
2. Open a new Workspace (call it B) in another MyEclipse Blue-Window.
3. Close the Workspace B.
4. As soon as B is closed, in the workspace A the compiling of the portal project starts, without any action on my side.
5. Upon compilation I get the error message that “JSR 168 Portlet API Libraries” are missing. The project doesn’t compile any more. The “JSR 168 Portlet API Libraries” are though visible in the Library List in “Java Build Path”.
6. Removing the libraries from “Java Build Path”, compiling the project, adding them and compiling again doesn’t help. The error is still there.
7. The only way of getting rid of the error is restarting MyEclipse Blue and repeating step 6.

Can you please provide help on this? We have to work often with more Workspaces at the same time and this problem is causing a lot of annoyance and wasted time.

Thank you very much in advance,

Paul P

Paul,

I think I have an idea… it does look like there is some cross-polination going on and the problem might be with incorrect config values.

Try this:
1. Shut down all instances of MyEclipse
2. Fire up workspace A, go to Window > Prefs > MyEclipse > Project Capabilities > Portlets, and hit “Restore Defaults”, then “OK” and then exit.
3. Do the same in step #2, but with workspace B, then exit.

Now try your scenario again, are things better?
