Hi!
I’m using Jboss4 and MyEclipse 4.1.
When I’m trying to start the server MyEclipse open the debug mode.
No messages are printing to the console.
I “stack” in this mode in never ending loop.
When I stop the server I get the right message in the console. (“The server shutdown succssefuly…”).
This problem is new, and I don’t know what I did worng.
Please Help!
mennei.Mennei,
Can you go to your Breakpoints view under the Debug perspective, right click in it and do a “Remove All” and click yes. Then shut down MyEclipse and restart it using the -clean command line argument on the command line as explained here:
http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-10280.htmlHi!
I am tring to map Message object with hibernate.
a) I have the follow Message.java file in package hello:package hello;
public class Message {
private Long id;
private String text;
private Message nextMessage;// Ctors.
public Message() {}
public Message (String text){
this.text = text;
}
// Setter and Getter methodes.
public Long getId(){
return id;
}
public void setId (Long id){
this.id = id;
}
public String getText(){
return text;
}
public void setText (String text){
this.text = text;
}
public Message getNextMessage(){
return nextMessage;
}
public void setNextMessage (Message nextMessage){
this.nextMessage = nextMessage;
}
}b) I have the Message.hbm.xml file in the same package as the Message.java file.
This is Message.hbm.xml:<?xml version=”1.0″ encoding=”UTF-8″?>
<!DOCTYPE hibernate-mapping PUBLIC
“-//Hibernate/Hibernate Mapping DTD 3.0//EN”
“http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd”>
<hibernate-mapping>
<class
name=”hello.Message”
table=”MESSAGE”>
<id
name=”id”
column=”MESSAGE_ID”>
<generator class=”increment”/>
</id>
<property
name=”text”
column=”MESSAGE_TEXT”/>
<many-to-one
name=”nextMessage”
cascade=”all”
column=”NEXT_MESSAGE_ID”/>
</class>
</hibernate-mapping>c) I’m using hibernate.cfg.xml file
<?xml version=’1.0′ encoding=’UTF-8′?>
<!DOCTYPE hibernate-configuration PUBLIC
“-//Hibernate/Hibernate Configuration DTD 3.0//EN”
“http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd”><!– Generated by MyEclipse Hibernate Tools. –>
<hibernate-configuration><session-factory>
<property name=”connection.username”>root</property>
<property name=”connection.url”>jdbc:mysql://localhost/test</property>
<property name=”dialect”>org.hibernate.dialect.MySQLDialect</property>
<property name=”myeclipse.connection.profile”>MySql profile</property>
<property name=”connection.password”>1</property>
<property name=”connection.driver_class”>com.mysql.jdbc.Driver</property><!– JDBC connection pool (use the built-in) –>
<property name=”connection.pool_size”>1</property><mapping resource=”hello/Message.hbm.xml” />
</session-factory>
</hibernate-configuration>
d) I put a manager class name HelloWorld.java
package hello;
import org.hibernate.Session;
import org.hibernate.*;
import org.hibernate.cfg.*;public class HelloWorld {
public HelloWorld(){}
/**
* @param args
*/
public void go()
{ // Adding configure method to read the properties from hibernate.cfg.xml
SessionFactory ses = new Configuration()
.addClass(Message.class)
.configure()
.buildSessionFactory();
Session session = ses.openSession();
Transaction tx = session.beginTransaction();
Message message = new Message(“Hi to everybody”);
session.save(message);
tx.commit();
session.close();
}
}I have jsp file that exeucate all. This is the code:
<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN”>
<%@ page import=”hello.HelloWorld” %>
<%@ page import=”java.sql.*” %>
<html>
<head>
<title>Searcher starting page</title>
</head>
<% java.util.Date date = new java.util.Date();
System.out.println(“The time now is:” + date);Connection conn = null;
try
{
String userName = “root”;
String password = “1”;
String url = “jdbc:mysql://localhost/test”;
Class.forName (“com.mysql.jdbc.Driver”).newInstance ();
conn = DriverManager.getConnection (url, userName, password);
System.out.println (“Database connection established”);
}
catch (Exception e)
{
System.err.println (“Cannot connect to database server”);
}
finally
{
if (conn != null)
{
try
{
conn.close ();
System.out.println (“Database connection terminated”);
}
catch (Exception e) { /* ignore close errors */ }
}
}HelloWorld hi = new HelloWorld();
hi.go();
%>
</body>
</html>but i get the next console:

… 33 moreCan someone tell me what I did worng???
Mennei.Where did you put your hbm.xml mapping file? If you look at the exception, that is the problem, Hibernate cannot find it.
Hi!
Thanks for your help.
I put the Message.hbm.xml in the same package as Message.java, the hello directory. After the deployment i can see the Message.hbm.xml in the WEB-INF/classes folder.I’m still can’t open my web application in debug mode.
Mennei.Are you generating your mappings to the default package, or into an actual package? Meaning, are your classes and hbm.xml files actually directly in the WEB-INF/classes directory and in your hibernate.cfg.xml file it just refers to them as /Message.hbm.xml or something like that? That is most likely the problem, please try using a full package, like com.test to generate your information into.
It’s a bad idea to use the default package for classes.
