Hi all, as title i need help to start GlassFish server on Eclipse. I'm working with Eclipse Helios 3.6 on Ubuntu 10.10.

I have downloaded and installed jee6 sdk from the oracle site. After this, i have downloaded the plugin GlassFish Application Server for eclipse (with install new software) from download.java.net/glassfish/eclipse/helios.
Now, where i open a new perspective of JEE, i create a new server and install the server on a directory i create. I think this is the correct method to install the GlassFish server...
But when i try to start the server (clicking on the green button start), appears this error:

"'Starting GlassFish 3.1 at localhost' has encountered a problem. The Eclipse plugin cannot communicate with the GlassFish server, status is :CREDENTIAL_ERROR"

Starting GlassFish 3.1 at localhost is the name of the server create (i left all properties by default).
Obviously i launch eclipse from terminal like root, cause the directory where i download and install the server is for root only.

I hope someone else can help me, so i can start to program in jee

Thanks
