Problem with Glassfish

[Arun Shiva]

Hir,

This is regarding the SOAP tutorial. I have problem with glassfish, I have downloaded the java ee sdk latest version and installed the glassfish as shown in the tutorial 5 but I could not start the server neither from eclipse nor form command prompt. MY OS is windows 7 64 bit java is 64 bit 1.7 jre also 1.7 and I have done everything accordingly shown in the tutorial but it says "There is a process already using the admin port 4848 -- it probably is another instance of a GlassFish server. Command start-domain failed." From the eclipse it says "The Eclipse plugin cannot communicate with the GlassFish server.... The Eclipse plugin cannot communicate with the GlassFish server.Please, check for antivirus software blocking or monitoring this port, or firewall configuration, or VPN setup which might block some ports..."

Please help me to solve this problem
