Java SE (Java Platform, Standard Edition)

Hi all, i have a problem, and i think is a JRE problem
The error is the following:
If i share a Web JSF Exadel project enterely, with the .classpath, the .project,
ect everything go ok. I can Check out the project
and work with it without problems.
But if i share only the JavaSource and the Webcontent of the same project
and the other files and folders like the .classpath, the .project, the ant folder,
ect are added to the subversion then appear the problem. When i Check out the project and build it (not with shift-alt-x Q but with the Build Project option of the Projec Menu in Eclipse)
appear an strange error that say: "The type Iterator is not generic; it cannot be parameterized with arguments <E>".


If i build the project using the build.xml file that came with the project everything is ok, but when i run the project into the Exadel the error
appear againt.

The error appear with all the eclipse versions from 3.1 to 3.3 and with all the ExadelStudio Pro versions from 3.5 to 4.0.4 and with the JRE versions 1.5.0_05 and 1.6.0_02

Any idea will be very appreciated.
