configuration in hibernate problem

[Rahul Shilpakar]

I am not getting that how did Hibernate know where the configuration file was located?

I am trying to practice hibernate using core java only. I created my client class main class, hibernate.cfg.xml, o.hbm.xml, and POJO class having getter setters need for mapping.

My code:

----------------------
Main Class : GoodHyber
----------------------
package hyber;
 
import net.sf.hibernate.SessionFactory;
import net.sf.hibernate.Session;
import net.sf.hibernate.cfg.Configuration;
import net.sf.hibernate.*;
 
import java.util.List;
import java.util.Iterator;
 

public class GoodHyber {
 
public static void main(String[] args) 
{
System.out.println ( "You are in main method boss..");

try 
{
                    
                    SessionFactory sessions = new Configuration()[B]// LINE 1[/B]
                    .configure ("conf/hibernate.cfg.xml")   [B]// LINE 2[/B]
                    .buildSessionFactory();      [B]// LINE 3[/B]
                    
                    Session session = sessions.openSession();

    Transaction tx=session.beginTransaction();

    HyberPojo pojo1 = new HyberPojo();
    pojo1.setTypeoftrans("Money");
    pojo1.setFromwhome("Me");
    pojo1.setTowhome("Rakesh");
    pojo1.setAmount(968.45);
    pojo1.setBalance(735.90);

    tx.commit();

    System.out.println ("Congrats u done it.");
} 
catch (MappingException e) 
{
// TODO Auto-generated catch block
e.printStackTrace();
} 
catch (HibernateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

HyberPojo.java
----------------
package hyber;
 

public class HyberPojo 
{
private int transid;
private String typeoftrans;
private String fromwhome;
private String towhome;
private double amount;
private double balance;

public int getTransid() {
return transid;
}
public void setTransid(int transid) {
this.transid = transid;
}
public String getTypeoftrans() {
return typeoftrans;
}
public void setTypeoftrans(String typeoftrans) {
this.typeoftrans = typeoftrans;
}
public String getFromwhome() {
return fromwhome;
}
public void setFromwhome(String fromwhome) {
this.fromwhome = fromwhome;
}
public String getTowhome() {
return towhome;
}
public void setTowhome(String towhome) {
this.towhome = towhome;
}
public double getAmount() {
return amount;
}
public void setAmount(double amount) {
this.amount = amount;
}
public double getBalance() {
return balance;
}
public void setBalance(double balance) {
this.balance = balance;
}
}

Now, i also tried the different which replace LINE 1

i.e. .configure("conf/hibernate.cfg.xml")



My Output is an Exception in between LINE 1 to 3

please guid me where am i wrong? Even though i have correctly mentioned the hibernate.cfg.xml file path.

besides this I am not providing any VM arguments to my main class through eclipse. also my properties are with in hibernate.cfg.xml file itslef as i read in book that we only need to give relative path of hibernate.cfg.xml file as configure method argument. :roll:

[avihai marchiano]

you are missing jar fromyour classpath.
the missing jar is dom4j

look at the exception:
org/dom4j/Attribute

[Rahul Shilpakar]

Thanks for reply.

As you suggested i added the dom4j and commans-logging which was required but still its giving me exception

What may be the problem. How did Hibernate know where we keep the configuration file?

I wonder how can i do this in Eclipse?
I am using Eclipse GANYMEDE.

[Kadle Rajesh]

Hibernate by default looks for "hibernate.cfg.xml" file in the class path of the application. So make sure you have that file in your class path.

If hibernate finds hibernate configuration properties file and xml files, xml file settings will override the properties file.

So please make sure you have the .xml file in your class path.

In your code you have specified "conf/hibernate.cfg.xml", if you dont have the "conf" directory, just try with "hibernate.cfg.xml".

I tried to set class path in COMMAND PROMPT and also runs my MAIN class in the same.

cmd.exe
------------
set path= //something
set classpath= absolute path to cfg.xml file (including conf file name); also my project jar; and also supporting jars;

java hyber.Goodhyber

Output
------------

:
WARNING : can not find the hibernate.cfg.xml

Guys please help me to solve it. What might be wrong with my program?

[Paul Sturrock]

Where is hibernate.cfg.xml deployed to? It needs to be in you class files, or in your jar file in the package conf. Is it?
