DuplicateMappingException: Duplicate class/entity mapping

2009-11-17T09:56:00.000-08:00

It turns out the deceptive exception can be thrown from an improperly formed Many-to-Many relationship declaration. I'm not going to take the time to document a correct declaration here but I was getting this misleading error message and was searching for an obvious problem with imports when it turned out to be the @ManyToMany annotation usage.

Spring with gwt-dispatch

pgt » Use Spring with GWT dispatch

So inspired by this post and the discussion over in the gwt-dispatch group I have converted my application over from Guice to Spring. The only variance from the pgt blog post is that I am using net.customware.gwt.dispatch.server.spring.SpringStandardDispatchServlet in my web.xml. Other than that my action handlers are getting called as expected.

Raible Designs | Running Hosted Mode in GWT Libraries (when using Maven)

Linking to Matt Raible's notes on the GWT Maven plugin setup. I have basically the same findings.

I've added the maven-war-plugin for building a war for deployment. I've also had some problems since I'm not on Snow Leopard yet and there are JDK 1.6 issues with GWT and JDK 1.6 on Leopard.

Putting some GWT-related posts over on my blog that primarily speaks to Java-related topics.

This is SQL:


SELECT *
FROM users
WHERE user_id = 1212;

This is Java:


package com.gwt.client.gin;

import net.customware.gwt.presenter.client.place.PlaceManager;

import com.google.gwt.inject.client.GinModules;
import com.google.gwt.inject.client.Ginjector;

public interface ListGinjector extends Ginjector {

 AppPresenter getAppPresenter();

 PlaceManager getPlaceManager();

The link for the countries.dmg file on this page should be: http://developer.apple.com/webapps/articles/countries.dmg

in reference to:

"So that you can play along at home and test out the code samples in this article, we’ve created a simple web application, based on Ruby on Rails, that implements a RESTful web service. The first step is to download the web application named countries (.DMG, 600 KB). It is based on a simple, database of public domain data containing four fields: A country index, country name, gross domestic product, and two-character country abbreviation.
Our application will perform operations on this database, based on RESTful requests received from a client. Understanding how to implement those requests from your Cocoa and Cocoa Touch applications is our ultimate goal.
When you download the countries web application (.DMG, 600 KB), it can live anywhere on your hard drive. Once it is downloaded, double-click the file REST Article Test Server.zip to create a folder called countries. We won’t need to do anything else to that folder.
Next up, let’s make sure we’ve got Ruby and Rails properly installed."

trouble with annotations and gwt-maven-plugin

2009-09-29T14:25:00.000-07:00

I'm working on my first project to combine maven with Google Web Toolkit. In an attempt to use google-gin and its annotation, I ran into some compile time problems because the gwt:compile was running before javac had not compiled the annotations into .class files.

I don't have an elegant workaround just yet but running the process as a two step compile with maven after a clean works:

mvn clean compile -Dgoogle.webtoolkit.compileSkip=true

followed by:

mvn gwt:compile

I didn't realize that Java to XPCOM was really possible but I guess it is. It would be nice if Java could implement XPCOM interfaces.
