5:34 p.m.
h i'm trying to setup a basic exemple ejb project :
my sessionBean :
package ejb3inaction.example;
|
| import javax.ejb.Stateless;
|
| @Stateless
| public class HelloUserBean implements HelloUser{
|
| public void sayHello(String name){
| System.out.println("Hello "+ name + "Welcome t Ejb3!");
| }
|
| }
my HelloUser class:
package ejb3inaction.example;
|
| import javax.ejb.Remote;
|
| @Remote
| public interface HelloUser {
| public void sayHello(String name);
| }
|
|
|
my persistence.xml file:
| <?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="chap1PU" transaction-type="JTA">
| <jta-data-source>chap1P</jta-data-source>
| </persistence-unit>
| -->
| <persistence-unit name="chap1PU">
| <jta-data-source>java:/chap1PU</jta-data-source>
| <properties>
| <property name="hibernate.hbm2ddl.auto" value="create-drop"
/>
| <property name="hibernate.dialect"
value="org.hibernate.dialect.PostgreSQLDialect"/>
| </properties>
| </persistence-unit>
| </persistence>
|
in jboss-5.0.1.GA/server/default/deploy
i got a chap1PU-ds.xml and his content:
|
| <?xml version="1.0" encoding="UTF-8"?>
| <!-- The Hypersonic embedded database JCA connection factory config -->
| <!-- $Id: hsqldb-ds.xml 76997 2008-08-12 22:29:19Z bstansberry(a)jboss.com $ -->

|

-->
| <metadata>
| <type-mapping>PostgreSQL 8.2</type-mapping>
| </metadata>
| </local-tx-datasource>
| </datasources>
|
i have copied the jdbc postgresal jar in jboss lib
and i got my test class:
| package ejb3inaction.client;
|
|
|
| import java.io.FileInputStream;
| import java.io.FileNotFoundException;
| import java.io.IOException;
| import java.io.Reader;
| import java.util.Properties;
|
| import javax.naming.Context;
| import javax.naming.InitialContext;
| import javax.naming.NamingEnumeration;
| import javax.naming.NamingException;
|
| import com.ibatis.common.resources.Resources;
|
| import ejb3inaction.example.HelloUser;
| import ejb3inaction.example.HelloUserBean;
|
|
|
| public class HelloUserClient {
| private static HelloUser helloUser;
|
| public static void main(String[] args) throws FileNotFoundException, IOException {
| try {
| //Context context = new InitialContext();
|
| Properties props = new Properties();
|
props.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
| props.setProperty("java.naming.provider.url",
"jnp://127.0.0.1:1099");
| props.setProperty("java.naming.factory.url.pkgs",
"org.jboss.naming");
|
|
| Context context = new InitialContext(props);
| //helloUser = (HelloUser) context.lookup("chap1/"+
HelloUserBean.class.getSimpleName() + "/remote");
| String a = "java:/";
| NamingEnumeration ne = context.list(a);
| while (ne.hasMore()) {
| System.out.println("A: " + ne.next().toString());
| }
|
| //helloUser = (HelloUser)
context.lookup("ejb3inaction.client.HelloUser");
| System.out.println("***>"+HelloUserBean.class.getSimpleName());
| //helloUser = (HelloUser) context.lookup(HelloUserBean.class.getSimpleName());
| // helloUser = (HelloUser) context.lookup("ejb3inaction.example."+
HelloUser.class.getSimpleName() + "/remote");
| helloUser = (HelloUser) context.lookup("HelloUserBean/remote");
| helloUser.sayHello("Curious George");
| } catch (NamingException e) {
| e.printStackTrace();
| }
| }
| }
|
when i try to execute it it give me the following error:
