Specification violation [EJB3 JPA 6.2.1.2] -You have not defined non-jta-data-source

Hello friends,

I am trying to create a web application using Spring 3.0.3, JPA 1.0, Hibernate 3, zkoss 5 and JBOSS 5.1 server with jdk support.

Following is list of jar files in my /WEB-INF/lib directory

commons-io.jar
org.springframework.*-3.0.3.RELEASE.jar
zcommon.jar
zcommons-el.jar
zhtml.jar
zk.jar
zkplus.jar
zul.jar
zweb.jar

You need to define a data source in your container (JBoss) and give it a jndi name and access it through org.springframework.jndi.JndiObjectFactoryBean.
Use BasicDataSource only for test purposes, it is not meant for production environment.

Hello Enrico Pizzi,

Thanks for the reply.

I will try creating jndi in my JBOSS and give it try too.

But can you please tell me what is wrong with current code using Basic data source? I am just making a test application currently to learn things in spring.

Thanks.

Your current persistence configuration requires a non-jta data source declared in your persistence.xml. The declaration involves giving the jndi name of the resource. Your jndi host is your container, so you must either register your SimpleDataSource as a jndi resource on JBoss, OR use a Datasource defined directly in JBoss.

The second option is the way to go, because it's simpler and more correct. Why more correct? Because in a j2ee application access to database should always be container-driven. This is because your application server gives you a more secure, monitorable, testable, and enhanced environment: think, for example, of the transactional services (jta transaction managers) that are tied to the datasource defined in the container, or the multi-datasource and datasource factory patterns.

Thus, always use container-driven datasources for your j2ee applications. Spring's own defined datasources like SimpleDataSource are only there for:
- non-web applications that still need database access;
- unit testing (with junit etc.).

Hello Enrico Pizzi,

Thanks for the answer.

Can you tell me how to make a configuration of Hibernate so that it does not require <non-jta-data-source>

Is there any settings for that.

I tried https://src.springframework.org/svn/...les/petclinic/ from my pc and it configured and run fine without any problem.

Now I am trying same things with some changes and it asks for <non-jta-data-source>

In that application they have used hsql in memory database and in my application also I am using hsql in memory database. I am using same Spring 3.0.3 jar files that I used with that application.

Only difference is that they used toplink classes and I am using hibernate classes instead.


Thanks.

TopLink and Hibernate are two very different ORM frameworks, and so their Spring integration also differs, but you shouldn't have any problem with Hibernate since it's maybe the most Spring supported ORM. I suggest you read chapter 13.3 of the Spring 3 reference guide.

Hello Enrico Pizzi,

Thanks for the reply.

I created no tx datasource in JBOSS and assigned it to <non-jta-data-source> tag in persistence.xml file and it seems to work.. But now I am getting following problem... in JBOSS. it says "mapped-name is required"

Do you have a WebServiceContext object mapped with @Resource? If so, please note that WebServiceContext resources need to be treated specially...remove the @Resource and the error should go away.

Hello Enrico Pizzi,

Thanks for the answer.

I think now problem is with zkoss implementation.

following is class that is creating resource annotation.
Look at function wireBeans()

Code:

---

package org.zkforge.zktodo2;

import java.lang.reflect.Field;

import javax.annotation.Resource;
import javax.servlet.ServletContext;

import org.springframework.context.ApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
import org.zkoss.zk.ui.Component;
import org.zkoss.zk.ui.util.GenericForwardComposer;

public class GenericSpringComposer extends GenericForwardComposer {

        private static final long serialVersionUID = -8554216461300908912L;

        private ServletContext servletContext = null;

        @Override
        public void doAfterCompose(Component comp) throws Exception {
                super.doAfterCompose(comp);
                this.servletContext = (ServletContext) comp.getDesktop().getWebApp()
                                .getNativeContext();
                this.wireBeans();
        }

        @Override
        public void didActivate(Component namespace) {
                super.didActivate(namespace);
                try {
                        this.wireBeans();
                } catch (IllegalArgumentException e) {
                        e.printStackTrace();
                } catch (IllegalAccessException e) {
                        e.printStackTrace();
                }
        }

        private void wireBeans() throws IllegalArgumentException,
                        IllegalAccessException {
                ApplicationContext ctx = WebApplicationContextUtils
                                .getWebApplicationContext(this.servletContext);
               
                Field[] fields = this.getClass().getDeclaredFields();
                for (Field f : fields) {
                        Resource annotation = f.getAnnotation(Resource.class);
                        if (annotation != null) {
                                f.setAccessible(true); // Make private fields accessible.
                                Object bean = ctx.getBean(annotation.name());
                                f.set(this, bean);
                        }

                }
               
        }

}

I am using code which is given on zkoss site.
I don't know if you are aware of zkoss but can you please tell me how to treat WebServiceContext resources specially

Thanks.
Thanks.

No, I didn't know of ZK till now. To make it work with Spring, I think you should use ZK Spring 1.1.0 Release, which is an integration framework between ZK and Spring, and follow this guide to set it up: http://docs.zkoss.org/wiki/Spring#ZK_.2B_Spring
