Miguel, ok - I think that I am closer to the problem now.
At the moment I am running the web app under tomcat 6 with the re- installed gwt 1.6.4 sdk, following the problematic upgrade. There now appears to be what looks like a classloader problem - the various servlets which this app runs cannot now be created. When the web app starts you get the 'Error loading WebAppClassLoader' message - and then 'ClassNotFoundException' for each of the servlets defined in the project - so none of the servlets work. I have checked that the entries visible in the 'Build Path' - and everything seems right. This problem appears to be isolated to the gwt project - if I create a new dynamic web project from scratch in eclipse - it runs ok - so this is not just something in the tomcat installation that has broken. Also, if I run an 'export to war' of the web app - and run it in a stand-alone tomcat web server - it seems to work. My guess is that somehow - during the upgrade something in the low- level classes which the web server has to class-load in order to create and run servlets has got broken. Unfortunately, if this assumption is right, I have no idea how to find out what the offender might be and fix it.
