GlassFish : Java EE Service Engine is now called sun-javaee-engine

Recently, the component name of the Java EE service engine is changed from "JavaEEServiceEngine" to "sun-javaee-engine". It is very easy for the end users to migrate their applications to the new name. All that is required is to open your existing JBI project in NetBeans, build and deploy.

These are the detailed steps:

1. Go to http://www.netbeans.org/community/releases/60/index.html
2. Click "Download Preview"
3. Select your platform and download "Full" version.
4. Open your JBI project with this new NetBeans, do a "Clean and Build Project" and "Deploy Project".

If you have Non-NetBeans projects, then the following program can be used to migrate your projects to the new name. You just need to compile it and run it. You can also modify this utility to server your purpose.
