The Eclipse plugin cannot communicate with the GlassFish server, status is :CREDENTIAL_ERROR

Question

I am able to start Glassfish through command line. However, when I try to start the server through Eclipse I encounter the following error:

The Eclipse plugin cannot communicate with the GlassFish server, status is :CREDENTIAL_ERROR

I have checked my login credentials (admin/adminadmin) and they are correct (I'm able to login into the admin console on port 4848 with the same user/pass). Here is my system info:

• OS: OS X 10.6.7
• Eclipse: Indigo Service Release 1
• Glassfish V3.0.1
• Glassfish Plugin: GlassFish Server Open Source Edition 3 (Java EE 6)
• GlassFish user/pass: admin/adminadmin

Please let me know if there is a solution to the problem.

Answer 1

Here is what worked for me - after some googling I saw a post saying the error message is misleading and it might be a port conflict. In my Eclipse I have a proxy server entry which uses port 8080 (same as GF). So I changed port to 9090 in domain.xml and GF started no problem. My system is Win7x64, Eclipse 3.7.1, GF 3.1.1

Answer 2

In the "Servers" view, right-click on the glassfish server and choose "Open"

Within the section "Application Server", ensure that "Use Anonymous Connection for Administrator Commands" is NOT checked off.

If checked, eclipse plugin does not use your login credentials (admin/adminadmin) .
