Solution 1

Found the answer. I need to run in JDK1.6. Once i changed the Java Compiler(right click project -> properties -> Java Compiler -> (Check) Enable project specific settings -> change the Compiler compliance level), its works fine now. Thanks.

Solution 2

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

Solution 3

When using Java 1.7, also check for the Execution Environment and set it to JavaSE-1.7.

You can look into the Execution Environment in:

Right Click -> Properties -> Java Compiler

And you have the option above Restore Defaults and Apply.

Solution 4

I had the same issue. for me the problem was one of my filters had an exception. specifically objectify - it was not loaded properly. you can delete the filter and see if that's it

how did you delete this filter? (I'm new to app engine)

[yonojoy]

To temporarily delete the filter, edit web.xml, comment out <filter> and <filter-mapping>
