Hi Guys,

getting error

InitialContextProperties -> ** NOT FOUND **

TransactionManager -> ** NOT FOUND **

CachedConnectionManager -> ** NOT FOUND **

What could be the cause ?

Can you tell us, which embedded server are you talking about? I haven't heard anyone running JBoss server under Tomcat.

Hi,

I am using Eclipse (Helios) + tomcat 6.0.29 + jboss-embedded-beta3.SP12 + Hibernate 3.x (final)

Basically I want to use ejb3 via hibernate for which i require J2EE Container, so i downloded "jboss-embedded-beta3.SP12-bin", which could be configured as Listener in conf/server.xml.

As per the installation guide for embedding it :-

(1) i have copied these jars under tomcat/lib folder :-
hibernate-all.jar
jboss-embedded.jar
jboss-embedded-all.jar
jboss-embedded-tomcat-bootstrap.jar
thirdparty-all.jar

(2) I have also copied the configuration folders & files from bootstrap folder to tomcat\lib
(3) I have added Listener in conf/server.xml file as

<Listener className="org.jboss.embedded.tomcat.EmbeddedJBossBootstrapListener"/>

(4) I have added listener in conf/context.xml file as

<Listener className="org.jboss.embedded.tomcat.WebinfScanner" ></Listener>

(5) My project file contains :

src/META-INF/helloworld-beans.xml

<?xml version="1.0" encoding="UTF-8"?>

<deployment
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="urn:jboss:bean-deployer bean-deployer_1_0.xsd"
            xmlns="urn:jboss:bean-deployer:2.0"  >


<bean name="helloWorldDatasourceFactory" class="org.jboss.resource.adapter.jdbc.local.LocalTxDataSource">
<property name="jndiName">java:/HelloWorldDS</property>
<property name="driverClass">com.mysql.jdbc.Driver</property>
<property name="connectionUrl">jdbc:mysql://localhost/hiber</property>
<property name="userName">root</property>
<property name="minSize">0</property>
<property name="maxSize">10</property>
<property name="blockingTimeout">1000</property>
<property name="idleTimeout">100000</property>
<property name="transactionManager"><inject bean="TransactionManager"/></property>
<property name="cachedConnectionManager"><inject bean="CachedConnectionManager"/></property>
<property name="initialContextProperties"><inject bean="InitialContextProperties" /></property>
</bean>

<bean name="HelloWorldDS" class="java.lang.Object">
	<constructor factoryMethod="getDatasource">
		<factory bean="helloWorldDatasourceFactory" />
	</constructor>
</bean>

</deployment>

I have also copied helloworld-beans.xml file in tomcat/lib/deploy folder


(6)src/META-INF/persistence.xml

<?xml version="1.0" encoding="UTF-8"?>


 <persistence xmlns="http://java.sun.com/xml/ns/persistence"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
          http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
        version="1.0">

<persistence-unit name="helloworld">
<properties>
	<property name="hibernate.show_sql" value="true"/>
	<property name="hibernate.format_sql" value="true" />
	<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5Dialect" />
	</properties>
</persistence-unit>
        
</persistence>        

(7) Bean Interface :- codes/MessageHandler

package codes;

public interface MessageHandler 
{
	public void saveMessage();
}

(8) Bean :- codes/MessageHandlerBean

package codes;

import javax.ejb.Stateless;
import javax.persistence.*;

@Stateless
public class messageHandlerBean implements MessageHandler 
{
	@PersistenceContext
	EntityManager em;
	
	public void saveMessage()
	{
		message message =new message("hello world with jboss ejb3");
		em.persist(message);
	}
}

(9) and finally user class :- codes/helloworld_jboss

package codes;

import org.jboss.ejb3.embedded.EJB3StandaloneBootstrap;
import javax.naming.*;
public class helloworld_jboss 
{
	public static void main(String[] s) throws Exception
	{
		EJB3StandaloneBootstrap.boot(null);
		EJB3StandaloneBootstrap.deployXmlResource("META-INF/helloworld-beans.xml");
		InitialContext initialContext=new InitialContext();
		MessageHandler msgHandler=(MessageHandler) initialContext.lookup("messageHandlerBean/local");
		msgHandler.saveMessage();
		EJB3StandaloneBootstrap.shutdown();
	}
}
