Hi all,

I got a problem in fact I launched Taverna 2.2 and it was impossible to 
load the workbench because of this error in the debug window :

Exception from method net.sf.taverna.raven.launcher.Launcher.main(String[])
java.lang.UnsupportedOperationException: This DocumentBuilder, 
"org.apache.xerce

Press any key to continue . . .
