Java GlassFish The module has not been deployed

Question

I have just created a web application with my local server and when I try to run this project, NetBeans answers me with this: /project_path/nbproject/build-impl.xml:1049: The module has not been deployed.

When I look at GlassFish log, I can read that there is a problem with connection to database. I use local MySQL. When I was adding this database to data source, I correctly filled input areas because when I run this project for the first time 2 days ago, everything was working perfectly.

GlassFish log:

Answer 1

Alot of times when working with glassfish and facing errors like that one just undeploy your web application restart glassfish deploy application clean and build and then run project and it will be fixed. At least this method works for me :)

Answer 2

Okay, so I have just created a new project, copied all the java classes into the new project from the old one and generated new persistence.xml. Hmm, working now, though the old persistence.xml and a the new one has the same context.
