Deploying WAR File to Glassfish

Question

I'm just getting to grips with the NetBeans 6.9 / Glassfish 3 combo, and have developed a Java EE app consisting of a WAR module and an EJB module. Having played around with the EJB side of things for a while, I went back to run the web code, and started having problems.

When I try to run the WAR file, it fails to deploy, and the error from the server is `WEB0113: virtual server [server] already has a web module [MyApp-war.war] loaded.' But I haven't edited the web side code since I last ran it, and I'm rather puzzled as to what it's trying to do.

I've tried the usual things: restarting the server, undeploying and redeploying the application, but to no avail... so if anyone with any more experience with Glassfish has any hints, they will be gratefully received!

Answer 1

Open GlassFish's Admin Console, see if the application is listed and try to undeploy it from there.

Answer 2

Did you create and deploy an enterprise application (ear) containing the ejb and web module? I don't think you can then deploy only the webapplication since its already deployed inside the ear. You'll have to redeploy the ear instead.

Answer 3

I had the same problem. Restart of glassfish server helped.

What was interesting, the Applications list did not have the application. Apparently some glassfish/netbeans bug.
