[nicanor.babula]

Hi everyone,

I just upgraded to gwt2.4, but when I load my application I get this exception:

[exception]

[/exception]

What could it be?

Also, questions of this kind are to be posted in the GPE group or this is the right one?

Thanks very much.

You need to add validation-api-1.0.0.GA.jar to your classpath.

[Thomas Broyer]

…or gwt-servlet-deps.jar (contains javax.validation and org.json)

[nicanor.babula]

Thank you very much. 

I added gwt-servlet-deps.jar and it works.

Best regards,

Nicanor Cristian Babula.

Strangely, this doesn't seem to work for me.
I'm trying to move a working GAE/GWT app to GWT2.4.
After putting gwt-serverlet-deps.jar on my class path, I still see
during the first RPC
