Activities and Places - Ant compilation

[Jeanpylone]

Hi there!

Is there some special flag/classpath to add when a GWT project using Activities and Places is compiled with Ant?

While it is compiling successfully with the GPE compilation, it fails under Ant with a stacktrace like this:

Any idea will be appreciated :)

I think the problem is in your application code and not an issue with a flag or adding anything to the classpath. Can you include your Mapper and Place(s) files?

[Thomas Broyer]

Well, if it compiles with the GPE, it's likely an issue with the Ant script, right?

It looks like the client-side classes haven't been compiled (javac) or that the output from javac is not in the classpath for the GWT compiler.

My bad, I didn't read that part.. damn..

"Classes referenced from annotations have to be compiled for GWT to be able to process them from within generators (as is the case for @WithTokenizers on a PlaceHistoryMapper)."

My Bad!!!

Sorry, I think I should sleep longer sometimes...

In fact I was doing it right (class compiled before gwt compile and so on ...) But my pathelement to class files was just wrong!

Thank you all for your answers !
