On the server side I want to use Spring DM and Hibernate.
Eclipse RCP and Spring DM builds the client.
I spent the last few evenings trying and searching for a working Spring DM/Hibernate example. I had a lot of classloading issues.
Yesterday I got it to work, you can download the plug-in here.
It's a simple application handling a User object and using HSQL as database.
I added all the dependent jars in the /lib directory. You can create separated plug-ins for them if you want.
Here a list of all the jar files, because thats where I had my problems:
- cglib-nodep-2.1_3.jar
- commons-collections.jar
- commons-dbcp.jar
- commons-pool.jar
- dom4j-1.6.1.jar
- hibernate3.jar
- hsqldb.jar
- jta.jar
- spring-core.jar
- spring-jdbc.jar
- spring-orm.jar
- spring-tx.jar // why is the org.springframework.dao package in this jar?
You can access the service in the Test class:
package com.blogspot.swissdev.springservice;
import org.osgi.framework.BundleContext;
/**
*
* @author Flavio Donze
*/
public class Test {
private BundleContext context = Activator.getDefault().getContext();
public void start() {
System.out.println("starting the test...");
UserService service = (UserService) context.getService(context.getServiceReference(UserService.class.getName()));
User user = (User) context.getService(context.getServiceReference(User.class.getName()));
user.setPassword("pass");
user.setUsername("user");
service.store(user);
for (User u : service.findAll())
{
System.out.println("User: "+u.getId() + ", " + u.getUsername() + ", " + u.getPassword());
}
}
}
And here is my Spring configuration:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

</props>
</property>
</bean>
<bean id="test" init-method="start" class="com.blogspot.swissdev.springservice.Test"/>
<!-- USER beans, POJO, DAO, Service -->
<bean id="user" class="com.blogspot.swissdev.springservice.UserImpl" scope="prototype">
</bean>
<bean id="userDao" class="com.blogspot.swissdev.springservice.UserDaoImpl">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<bean id="userService" class="com.blogspot.swissdev.springservice.UserServiceImpl">
<property name="userDao" ref="userDao"/>
</bean>
</beans>
To setup your workspace with Spring DM read the first part of my previous post.
For this example I used:
Eclipse 3.4 RC3
Spring Dynamic Modules for OSGi(tm) 1.0.2
