I'm just getting to grips with the NetBeans 6.9 / Glassfish 3 combo, and have developed a JEE 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!
