[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
Hi Andrew, This is confusing, but the App Engine SDK and the GWT SDKs are separate SDKs (one does not contain the other) and they are added via separate preferences. Trying to add the GWT SDK via the App Engine preferences will fail in the manner that you described. To clarify, if you want to add a GWT SDK you need to navigate to *Window Preferences*, or *Eclipse Preferences* if you are on Mac OS X. Open the * Google* entry in the left pane and select *Web Toolkit.* On Tue, Sep 15, 2009 at 10:57 AM, AndrewG andrew.g...@rcrt.co.uk wrote: Miguel, I have now tried this - but not had any luck making it work as yet.

[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 ?

Let us know when you have something.

[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.
