Google App Engine not being accessed via localhost

I am using Mac OS X 10.7.4, app engine sdk 1.7.0, eclipse juno and Java as programming language. The problem is that App runs perfectly well when deployed on appspot but does not work on localhost. When run as web application on port 8888 or any other port (if change it from the configuration), the log represents server is running but when I hit the URL, nothing happens and after some time connection times out. When, debugged it gives the error: Cannot connect to VM. Logs from console for both run and debugged are shown below, kindly help me, I have searched all over the 'net but could not find the solution.

Log when Debugged:

ERROR: transport error 202: handshake failed - connection prematurally closed
ERROR: JDWP: Failed to initialize transport via localhost:49741, trying localhost via 127.0.0.1:49741
ERROR: transport error 202: recv failed during handshake: Connection reset by peer
ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)

FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)

Log when run:

Have you tried running it from the command line? It looks like you're trying to start it in the debugger as well.. no? Try running from the command line, make sure that works. Then try running it from eclipse with "Run" not "Debug" and make sure that works before trying the debugger. Appengine is a little bit particular...

Check the following:

1) If the application has actually started. Enter "ps ax | grep java" in terminal 2) If the application has bound to the port. Install nmap (not sure how to do it on mac) and run it with "nmap localhost". You will see a list of ports and protocols used. If you don't see 8888 with http then something is wrong.
