Dear Google App Engine group members:

Hello, I am new to this gourp.

I tried to test my application using JUnit.
My application uses rpc, memcache and jdo.
When I run the test with GWTTestSuite,
some errors occured and I could not test my application.
Below is the error showed.

Starting HTTP on port 0

I can understand the PMF name is duplicated.
But I think "war/WEB-INF/classes/META-INF/jdoconfig.xml" was
copied from "baz/src/META-INF/jdoconfig.xml" and
I can not avoid the duplication.

As a test, I rewrote "transactions-optional" into "transactions-
optional0"
in "baz/src/META-INF/jdoconfig.xml".
Then I got another error below.
