Republish project error with Eclipse

Question

Hi guys,

I have a problem with eclipse and my project. When I start the server (weblogic 10.3) and publish my project, all work fine.

But when I modify a class and republish the project (without restart the server), I get the following error:

   weblogic.application.ModuleException: 
    at weblogic.servlet.internal.WebAppModule.startContexts(WebAppModule.java:1373)
    at weblogic.servlet.internal.WebAppModule.start(WebAppModule.java:468)

    Truncated. see log file for complete stacktrace

    at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:251)

If I restart the server, it work.

My hibernate jar are in the project (WEB-INF/lib).

I don't understand this error.

Thanks.

Hot deployment (or fastswap as it's called in Weblogic) (redeploying your application without restarting the application server) is always a bit sticky. I haven't worked much with Weblogic, but for example JBoss supports hot deployment but discourages any reliance on it.

According to this cite therd are a limited number of changes that a fastswap can handle. I think you're running into a similar problem.

I suspect that you simply need to get used to restarting your application server every once in a while.
