Unable to start Google APP Engine java.lang.NoSuchMethodError: org.mortbay.thread.Timeout

This usual indicates problems with the classpath. Do you have multiple versions of Jetty in your classpath by any chance?

To identify duplicate classes in eclipse, hit Ctrl+Shift+T to bring the 'Open Type' dialog. Search for the class org.mortbay.thread.Timeout. Ideally it should only come in gwt-dev.jar, but I suspect in your case some other jar file would also have it.

Also open .classpath in your eclipse

GWT container comes before the APP ENGINE

<classpathentry kind="con"

path="com.google.gwt.eclipse.core.GWT_CONTAINER"/>

<classpathentry kind="con"

path="com.google.appengine.eclipse.core.GAE_CONTAINER"/>



I had the same issue and I swapped the order of the classpath

and my errors are

gone now.

Mirroring Subversion Repository

Create a new repository to be the mirror:

·         svnadmin create MIRROR_CONTAINER

·         Create a "pre-revprop-change" action by creating a hook script by the same name.

o        Go to MIRROR_CONTAINER\hooks.

o        create a file named pre-revprop-change.bat

o        The contents will be as follows

Change the <<SVN USER>> to the user who will be performing the sync

IF "%3" == "<<SVN USER>>" (goto :label1) else (echo "Only the syncuser user may change revision properties" >&2 )

exit 1

goto :eof

:label1

exit 0

·         Save this file

·         Initialize a path within the repository to contain the mirrored data, and specify the source by

o        If the path has spaces then enlose them with the double quotes

o        For example my remote repository (MIRROR_CONTAINER) was in my shared folder so I use like the following

·         svnsync init --username <<SVN USER>> file:///"<<MIRROR_CONTAINER>>" <<BASE SVN location>> svn://162.66.224.77:48000/UFG

·         svnsync sync --username <<SVN USER>> file:///"<<MIRROR_CONTAINER>>"
