[appengine-java] Re: Eclipse GWT update error
Miguel, I have now tried this - but not had any luck making it work as yet. I have downloaded and unzipped 'gwt-windows-1.6.4' - then put it into eclipse/plugins. If I try to 'Add App Engine SDK' - it just says: Failed to Initialise App Engine SDK at ./gwt-windows-1.6.4 - don't know why. One obvious thing - don't know if its significant - if you look inside the dirs for the other gwt versions installed - they have a number of things, like: appengine-sdk-plugin.jar, META-INF directory, etc as well as an appengine-java-sdk-xxx directory, but the newly downloaded/ unzipped directory only contains a 'gwt-windows-1.6.4' sub-directory.

[appengine-java] Re: Eclipse GWT update error
Miguel, thank you - just before I picked up yr msg I figured out that I had tried to install it in the wrong place, and tried again. I have now (re-)installed the 'web toolkit' at v1.6.4, but I haven't yet reinstalled the app engine to its previous state. With just the toolkit re-installed, I am now getting a different set of errors: Project xxx is missing required library .. com.google.appenginesdkbundle_1_2_1 where the missing jars are things like: appengine-tools-api.jar, appengine-local-runtime-shared.jar, etc'. does this mean that the gwt sdk v 1.6.4 is closely tied to the appengine vn that was broken during the upgrade? - or is something else wrong - at the moment eclipse has appengine v1.2.5 installed - prior to the upgrade it was 1.2.1. I would like to get back to the configuration that I had before the upgrade (which worked) - but the only vn that I can see on the download page is v1.2.5 - so not sure where to get the 1.2.1 version - or is this a red herring and the errors are being caused by something else ?

[appengine-java] Re: Eclipse GWT update error
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.
