Glassfish 3.1 CREDENTIAL_ERROR in Eclipse

Question

I can\'t start Glassfish 3.1 on Eclipse Indigo with \"Oracle Glassfish Server Tools\" plugin on Windows 7. After installing the plugin, I\'ve chosen \"New\" -> \"Server\" in

Answer 1

I got the "The Eclipse plugin cannot communicate with the GlassFish server, status is :CREDENTIAL_ERROR" error too.

For me it was a Firewall problem. -- For some reason the Firewall (configured by the IT) blocks eclipse to communicate with Glassfish on port 4848, by default used as "Admin Server Port".

But port 8080 is not blocked.

My workaround was to switch the ports in the domain.xml

Now I can start the server from eclipse. And access the normal pages in the browser (because 4848 is not blocked for the browser).
