Hi,

I am using vaadin on a GAE project and I am having the following problem when server is starting:

[code]

Vaadin is running in DEBUG MODE.
Add productionMode=true to web.xml to disable debug features.
To show debug window, add ?debug to your application URL.

Either disable push, or adjust your server.policy for the application ( allow modifyThreadGroup )

Hi Petrus,

I am not enabled push and I can not change server policy to allow modifyThreadGroup because I am working with Google App Engine. Thank you for these shots.

Any suggestions? Thanks in advance.

Check if you packaged any atmosphere libraries with your application, if so remove them ( you wont need them if you disabled push ).

You are right!.. I removed atmosphere libraries removing the following line fom ivy.xml:

<!-- Push support -->
        <dependency org="com.vaadin" name="vaadin-push" rev="&vaadin.version;" />

After save and restart no problems occur.

thanks and regards.
