Re: Restlet-GWT compile error

[Doug Alcouffe]

Thanks Rob. I created a very simple application using the GWT applicationCreator and I have attached. I just added one line to the client Foo.java class that makes a org.restlet.gwt.Client.get() method call. I have modified the Foo-compile script to include the path to the org.restlet.gwt.jar 1.1snapshot file. When I run I get the stack trace shown below (same as my original post). It seems I am missing something small that is causing this but still not sure what that is. The steps I followed were to download the latest GWT 1.5RC1 distribution from the GWT site. I next go the the Restlet site and get the development version of the distribution. I then create the simple app and compile. Is there anything else I should do.

The only other environment element of interest is the jdk version which is 1.5.0_10 but that should not matter since GWT is using the JRE emulation library. For now I have switched to use the GWT RequestBuilder and everything works fine (of course I am limited to GET and POST).

Your test case is not blowing up for me ... I don't use Maven *at all* but I am trying to learn a little bit about it and set that up to see if that could be the trouble. I'm also using Ubuntu 8.04 to keep apples to apples.

    Hey Rob,
    Thanks for the reply.  I am on Linux (Ubuntu 8.04) and using GWT
    1.5RC1.  The one thing that may be different is that I am using
    the GWT Maven 2 plugin for my builds.  I have attached a simple
    example (default that gets created with the GWT Maven archtype)
    that is a simple GWT-RPC example.  I have added one line in the
    client App.java class that has a restlet Client.get() method
    call.  This line is commented out to show that the project will
    build fine.  When the line is uncommented then I get a GWT compile
    error.

    I figure it must have something to do with the fact I am using the
    Maven plugin but I am not sure where the issue is.  I will try to
    use the standard GWT command line project builder and see if the
    problem still shows up.  If you have a chance to try and recreate
    that would be great.

    thanks,
    Doug

    Hi Doug, I'm not getting that error from Restlet trunk or
    snapshot, compiling on Linux or Mac with GWT 1.5RC1.  I think
    Jerome compiles on Windows, the poor fellow.  Anything different
    about your setup -- like using GWT 1.5 trunk instead of RC1?  If
    you can give me a little more environment details, I'll try to
    set it up and reproduce.  If the code is something you can share,
    that would be helpful too.
