Answer 1

I had a condition where a servlet defined in the web.xml with non existent class name. I specified proper class name, worked!

Answer 2

i had the same issue. Seems that Plugin is stocked on creating and opening the socket for the server. i don't really know why happens, I've resolved in this way.

1. Open Run Configurations.
2. Open Server tab. Change the Embedded server Port.

3. Open Arguments tab.

   3.1 - VM arguments box. i've deleted all that stuff there and just let this line and save changes and run it.

-Xmx512m -javaagent:/Applications/eclipse/plugins/com.google.appengine.eclipse.sdkbundle_1.7.5/appengine-java-sdk-1.7.5/lib/agent/appengine-agent.jar

It has worked pretty good 4me. If someone know which events or configuration change are the reason for . please let us know it

Answer 3

I had the same problem. I justed changed the port from 8888 to 80 in the Debug Configuration and it worked for me.

Answer 4

It happened with me too. In my case, I had Run the project and due to some error in my code, the Project ran with errors. So, I debugged it and Run it again but without cancelling the earlier one in the console and it gave me that error. After cancelling or stopping the Project, it ran fine.
