My presentation of GWT 2.4

I have recently done a presentation of GWT 2.4
It is now available on slideshare.net :

I might work on it again later. To make it a bit nicer.

M2E problem : Plugin execution not covered by lifecycle configuration

February 18th, 2012 No comments

I am adding to the blogosphere of development-related blogs another post about the “Plugin execution not covered by lifecycle configuration” error.

The M2E Plugin 1.0.0 is integrated into Eclipse Indigo (3.7). Apparently, M2E connectors, which are a bridge between Maven and Eclipse, require to provide a connector for every plugin that is used in the build.
And if no connector is available, M2E shows the following annoying errors in the Eclipse problems view :

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-antrun-plugin:1.7:run (execution: run, phase: validate)

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-resources-plugin:2.5:resources (execution: default-resources, phase: process-resources)

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-resources-plugin:2.5:testResources (execution: default-testResources, phase: process-test-resources)

Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:properties-maven-plugin:1.0-alpha-2:read-project-properties (execution: default, phase: initialize)

Plugin execution not covered by lifecycle configuration: org.apache.cxf:cxf-codegen-plugin:2.2:wsdl2java (execution: generate-sources, phase: generate-sources)

Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:hibernate3-maven-plugin:3.0-SNAPSHOT:hbm2ddl (execution: default, phase: compile)

Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-ear-plugin:2.6:generate-application-xml

To avoid these errors, it is necessary to modify the pom.xml file so that M2E will not complain about it.

These are the extra lines that I added in my parent pom.xml :

	<build>
<pluginManagement>
	<plugins>

                  only. It has no influence on the Maven build itself. -->

Coding my first Android application

January 1st, 2012 No comments

I finally got the time to develop my first small Android application.
Technical environment :
– Eclipse Indigo
– Android SDK 2.3.3 (Gingerbread)
– An Android phone with Android SDK 2.3.4

I tried to go a little bit further than the traditional “Hello World” sample.
The application, called TeamManagement, is still a simple one : type in a name of a project member and it will display what his role is and when he arrived in the project. That’s it. I explored some nice features : relative layout, autocompletion, popup, menu at the bottom, show/remove image etc.

Main

The project inside Eclipse has the following structure :

The file /MyProject/res/values/strings.xml is where the name of the application is set.

<string name="app_name">TeamManagement 1.0</string>

I chose to organize the layout programatically, instead of declaratively (main.xml) and created a single activity called MyProjectActivity :

Eclipse Dali vs Hibernate Tools

May 8th, 2011 No comments

The process of mapping tables to entities is greatly simplified with tools like Eclipse Dali and Hibernate Tools, both available as Eclipse plugins. It avoids mapping them by hand, which in my opinion is prone to mapping errors and takes more time. And I really do not see why one should map them by hand when great tools like Eclipse Dali and Hibernate Tools are available.
In my book, I describe the use of the Eclipse Dali plugin to automatically generate the entities.
Lately I have also used Hibernate Tools and I have already noticed a few differences between these two tools.
I am going to list some of these differences.
