Wicket + JPA + Spring

Hello dear friends

I have been this weekend testing the combination of Wicket + JPA + spring. It was Very nice!!!!

At the beginning I discovered a page where to set up easily a project. Using http://www.jweekend.com/dev/LegUp I generated the mvn command to create the project:

mvn archetype:generate -B -DarchetypeCatalog=http://legup.googlecode.com/svn/repo/archetype-catalog.xml -DarchetypeArtifactId=wicket-spring-jpa-archetype -DarchetypeGroupId=com.jweekend -DarchetypeVersion=0.8.4 -DgroupId=com.mycompany -DartifactId=mycompany -Dversion=1.0-SNAPSHOT -Dpackage=com.mycompany

Then I transform the project to be opened by eclipse using the command:

mvn eclipse:eclipse inside the generated project

Then we can run Start.java

In the browser http://localhost:8080/ we will see running the example, using the Event object to persist.

We can change the persistence.xml to connect with mysql

<properties>
<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/javatest" />
<property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" />
<property name="hibernate.connection.password" value="root" />
<property name="hibernate.connection.username" value="root" />
<property name="hibernate.hbm2ddl.auto" value="update" />
</properties>

Be sure also to add mysql to the pom.xml in order to connect to mysql

<dependency>
 <groupId>mysql</groupId>
 <artifactId>mysql-connector-java</artifactId>
 <version>5.1.14</version>
 <type>jar</type>
 <scope>runtime</scope>
</dependency>

Then we run again the program and the connection with mysql is ready.
