[appengine-java] Re: Eclipse start server error after update to 1.2.6
Hi Keith and Peter, This helped me, thanks. It would help others if the release notes of the eclipse plugin http://code.google.com/eclipse/ mentioned that upgrading would break existing projects. I was assuming that I had broken something until I remembered that I upgraded recently. In case it helps here is the VM argument I used. -javaagent:/Applications/eclipse/plugins/ com.google.appengine.eclipse.sdkbundle_1.2.6.v200910131704/appengine- java-sdk-1.2.6/lib/agent/appengine-agent.jar Thanks, -Kris On Oct 14, 2:13 pm, Keith Platfoot wrote: > Hi Peter, > As the message indicates, the local development server in App Engine 1.2.6 > now requires the use of a Java agent.

[appengine-java] Re: Eclipse start server error after update to 1.2.6
Hi guys; I am getting the same issue as I just upgraded my sdk to 1.2.8. Where can I find the launch configurations for app engine. Please help. I am getting following exception while running the server. Unable to locate the App Engine agent. Please use dev_appserver, KickStart, or set the jvm flag: "-javaagent:/lib/agent/ appengine-agent.jar" On Oct 20, 3:00 am, Kris Carle wrote: > Hi Keith and Peter, > > This helped me, thanks.

In eclipse select "Run Configurations..." from the "Run" main menu ... in the dialog that pops up, you you see a "G" icon in the tree view on the left and a "list" of configurations under that, (at least one), select your personal favorite, click on the"(x) arguements" tab and add the appropriate config, on my system it's: -javaagent:"C:\Program Files\eclipse\plugins \com.google.appengine.eclipse.sdkbundle_1.2.8.v200912040616\appengine- java-sdk-1.2.8\lib\agent\appengine-agent.jar" On Dec 6, 3:21 pm, Tahir Akram wrote: > Hi guys; > > I am getting the same issue as I just upgraded my sdk to 1.2.8. > > Where can I find the launch configurations for app engine.
