Description

Hi,

I cannot launch a GWT app in hosted mode with the gwt:run goal. I get a serialization error :
[INFO] StandardContext[]ERROR: The serialization policy file '/test.GMavenTest/3D8C9ED7A7ACB57FC755C1283A84575C.gwt.rpc' was not found; did you forget to include it in this deployment?
[INFO] StandardContext[]WARNING: Failed to get the SerializationPolicy '3D8C9ED7A7ACB57FC755C1283A84575C' for module 'http://localhost:8888/test.GMavenTest/'; a legacy, 1.3.3 compatible, serialization policy will be used. You may experience SerializationExceptions as a result.

And then I get serialization exceptions.

Look at the attached sample project.

It seems this is not due to gwt-maven-plugin.

Try to implements IsSerializable instead of Serializable in your ServiceDTO class, this should work.

Maybe this isn't a bug, then, but I'm having the same issue. When I build my project with maven using the gwt-maven-plugin's compile and generateAsync goals, if there has been a change to serialized classes in my project that would require a change to the serialization policy file and/or files that reference it (the .gwt.rpc file), those changes are not reflected. I get the serialization policy not found error message, referencing a policy name that is not the name of the .gwt.rpc file packaged up.

Workaround: Run GWT Compile with the Google Eclipse Plugin on the project before packaging. This surprises me, though, because even when I do "mvn clean package" this still solves the problem.

This is probably not a valid bug, and it's over a year old ... please recreate with a current version or close the defect.

Have you tried reproducing it? I have been hit by it until I moved to IsSerializable exclusively.

I have seen this again, with GWT 2.4.0 , Plugin version 2.4.0 and gwt-dispatch. While running in dev mode and throwing a Serializable exception, I get

Check out the gwt maven archetype. You need to adjust various path settings in pom.xml.
