Errors while upgrade GWT to v2.4

[GoogleCodeExporter]

What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?
.xml files generated and run without errors while compiling.

What version of the product are you using? On what operating system?
operating system is Windows.
I make the compiler to be jdk1.7 instead of jre1.5.
I set these in the Environment Variables:
classpath point to C:\Program 
Files\Documentum\dctm.jar;C:\Documentum\config;%GWT_HOME%;%GWT_HOME%\gwt-user.ja
r;%GWT_HOME%\gwt-dev.jar;%GWT_HOME%\gwt-servlet.jar;%junit%
GWT_HOME D:\products\DSS 
2012\eclipse-jee-indigo-SR2-win32\eclipse\plugins\com.google.gwt.eclipse.sdkbund
le_2.4.0.v201205021203-rel-r37\gwt-2.4.0
JAVA_HOME "C:\Program Files\Java\jdk1.7.0_05"

JUNIT_HOME D:\products\DSS 
2012\eclipse-jee-indigo-SR2-win32\eclipse\plugins\org.junit_4.8.2.v4_8_2_v201103

In the eclipse --> Preferences --> Java --> compiler --> Compiler compliance 
level to 1.7
In the eclipse --> Preferences --> Java --> Installed JREs --> set it to 
jdk1.7.0_05

Please provide any additional information below.
I am trying to upgrade GWT to v2.4. I am facing problems. When Run As -> Ant 
Built (after upgrade the project), the .xml files are missing (not generated in 
the project) and the project build successfully, but there is strange behavior 
which shows errors in the console. I will post the errors that are appearing 
(some of them).

The errors that are appearing while doing the compiling (the result I got is 
successfully compiled)

[GoogleCodeExporter]

I managed to solve some of the errors appeared in the code by adding three jars.

First, I added these two files into the classpath:
1- validation-api-1.0.0.GA-sources.jar
2- validation-api-1.0.0.GA.jar

Then I added the three jars into the library and to war/WEB-INF/lib
1- validation-api-1.0.0.GA-sources.jar
2- validation-api-1.0.0.GA.jar
3- gwt-servlet-deps.jar

But still I have other things like the below problems. Any help or clue.

I used to have .xml files before upgrading GWT and the compiler, but after I 
compiled the code. The .xml files disappeared. 
what should I do?
Please Help.

I discovered that GWT 2.4 is working with JAVA 6 (not Java 7) and also I have 
to set compiler compliance level to 1.6. 

Even though, I am still trying to solve this problem. 

My real problem is that before upgrading to GWT 2.4 I was getting .xml files 
generated, but now I am not getting them. So I don’t how to get them 
generated. Do I really need these .xml files or not. Thank you again and 
looking for an answer.

Did you find a solution for the "Invalid Unit" thing? I have the same problem 
and no clue, what's the reason. Googling for it only matches this page.. :-/
