Accessing GWT app deployed on Jetty fails

[Musicman75]

Hello,

I've created a GWT war project with two subprojects.
When starting the server (Jetty standalone), the war is loaded:

2010-11-08 14:50:51.648:INFO::Deployable added: C:\Users\beutelsn

When accessing the war with the browser, I only get a popup with this
message:
---------------
GWT module 'com.XXX.Application' may need to be (re)compiled
--------------

In hosted mode everything works fine.

The war is created by maven. Here's my pom.xml:

Any ideas how I can solve my problem?

Thanks a lot for any hints.

I use Eclipse projects instead of maven, but I do see similar errors
when I create and deploy a war file without doing GWT compilation
first. After GWT re-compilation and re-deploying the war file the
errors disappear.

That's Why i posted my pom file. I think the maven execution is done
in the wrong order.

Could anyone please post a pom file to create a war and compile the
GWT app before?

What mvn command are you using? In this POM, gwt-maven-plugin is
executing gwt:compile during the prepare-package phase, so you should
run "mvn package" to trigger it.

HTH,

I executed mvn clean install, mvn clean package with and without
executing mvn gwt:compile before.
Same problem with all generated war files.

I solved the issue.

I've to add webAppDirectory to the GWT maven plugin.
The generated files were not placed in my webapp directory. They were
created in the target directory.
The webapp only contains a few files, but not all of them.

Here's my actual working pom file:
