Glassfish-应用名称已在使用中

Question

---

I've come to an hold with my programing because I'm getting an error from glassfish. I'm using NetBeans IDE 7.3 for this project. And I've built a simple program which runs over the web(jsp file etc). But I keep on getting the weirdest error display from glassfish. I've searched the internet for my solution and found people posting similar things, but I never seem actually manage to fix it because I don't really understand the post which I've read.

So what is the error that I get at startup? First time I run it I get this from the Output

Starting GlassFish Server 3.1.2
GlassFish Server 3.1.2 is running.

The actually name of the project is ÄrendeWebApplication and sure it's a weird name for some people. Well anyhow I tried to run the application again just to make sure it's not something spooky going on, and I got a totally different error message.

Alright so this is the weirdest part since it's complaining that the name of my application is already in use? So I thought first it could perhaps be something with the database, but went to see the “Java DB Database Process” and it seemed fine, will post it too just in case

So the database is not the problem “I Believe” so I went later to check on the Glassfish server 3.1.2 and I found some warning messages which read

And here is where I've tried different things, well I thought it first complained about the name, it's alredy in use right…. So I deleted the application and moved it to another place on my hard drive and well, I wouldn't be posting this if it worked. Then I started considering that perhaps the database was something wrong with, I went to the console admin in glassfish to check the connection and the Ping and showed me that it worked as it should. Also perhaps important information is that I've connected glassfish through MySQL, but I hardly believe that this is the problem. I then stumbled across someone saying that you could force “redeploy via Eclipse” well first problem here is that I'm not using Esclipse and second problem is I've searched A LOT to find if there is a “Force redeploy in NetBeans” and that is not the easiest task in life. So I believe this is perhaps my last stop hopefully and maybe someone here could help me out.

Answer 1

here are some steps you can try:

1. Fix your projects name :3
2. If your problem is the one the question title suggests, undeploy your application first, then redeploy. You can easily undeploy and force redeploy in the Glassfish Admin Gui ( http://localhost:4848 ).
3. If your application still does not work, update your question with proper formatted log messages of the actual problem.
