I don't know what was going on. :-( The reinstallation does not have any effect. I recompiled the example 3 times with the given ant script (targets clean,deploy) Every time i get a complete different ear (in size ) The last build succeds. I was able to start the application. Background: I use eclipse together with exadel studio. i downloaded the seam sources with eclipses CVS provider into an eclipse project. There i can build seam and any example without problems, except seam-space. This environment seems to be a little bit unstable:-( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4013507#...
