GWT packaging to war: Has Ant the wrong java version? - gwt

Question

I want to package my GWT 2.3 Application to a war file and deploy it on a weblogic server. I found this solution with ANT http://www.rubiconred.com/blog/build-package-a-gwt-app-to-war-using-ant/. But there is a Problem. The compile target throws an error and it looks to me like ANT is using the wrong Java version. But when I do Run As -> Ant Build... -> JRE The version is correct (1.6.0_11). So the solution from this question did not work. And I am yet not so sure if the java version is the problem.
The console output looks like this:

So my question is:
Is the Java version from ant the problem?
Or:
Is there an easier way to package the GWT application to a war file, then an ant script?
I tried some things, but nether did work.

Answer 1

Is the Java version from ant the problem?
No.
It looks like you're missing dependencies from the classpath (specifically the Bean Validation API, ICU4j, Apache Commons Lang and the Servlet API).
Is there an easier way to package the GWT application to a war file, then an ant script? I tried some things, but nether did work.
It depends how you build your project. If you're using Ant already, then use Ant to package your WAR; if you're using Maven, then use Maven; if you're using Make, then use Make; if you're using a shell script, then continue with it; etc.
If you don't have a build script and only rely on your IDE, then you have a more severe problem than packaging a WAR. But still, you can do that from within Eclipse (I know it can be done, I don't know how however).
