hi..
I am using hibernate to connect to database.i have a composite key(firstname and lastname).
I am getting error as:
Remote Exception: java.rmi.RemoteException: EJB Exception: ; nested exception is
:
java.lang.ExceptionInInitializerError

My bean class and composite id classes are as:

package com.iwms.hibernate.JavaBeans.TEST;

public class Try {
/**
*
*/

private TryCK tryCK;
private int age;

public Try() {
tryCK = new TryCK();
}

public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getFirstname() {
return this.tryCK.getFirstname();
}

public void setFirstname(String firstname) {
this.tryCK.setFirstname(firstname);
}

public String getLastname() {
return this.tryCK.getLastname();
}

public void setLastname(String lastname) {
this.tryCK.setLastname(lastname);
}
}

package com.iwms.hibernate.JavaBeans.TEST;

import java.io.Serializable;





public class TryCK implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private String firstname;
private String lastname;

public TryCK()
{

}

public TryCK(TryCK tryCK)
{
this.firstname=tryCK.firstname;
this.lastname=tryCK.lastname;

}

public boolean equals(Object obj) {
if(this == obj)
return true;
if((obj == null) || (obj.getClass() != this.getClass()))
return false;
TryCK tryCK = (TryCK)obj;
return (this.firstname.equals(tryCK.firstname) &&
this.lastname.equals(tryCK.lastname));
}

public int hashCode () {

int result;
result=firstname.hashCode();
return result;
}

public String getFirstname() {
return firstname;
}

public void setFirstname(String firstname) {
this.firstname = firstname;
}

public String getLastname() {
return lastname;
}

public void setLastname(String lastname) {
this.lastname = lastname;
}



}

Mapping file is as:
<hibernate-mapping>

<class name="com.iwms.hibernate.JavaBeans.TEST.Try" table="TRY">
<composite-id name="id"
class="com.iwms.hibernate.JavaBeans.TEST.TryCK">

<key-property name="firstname" column="first_name"
type="java.lang.String" length="30" />
<key-property name="lastname" column="last_name"
type="java.lang.String" length="30" />


</composite-id>

<!-- Normal properties of a java class -->


<property name="age" type="java.lang.Integer" column="AGE" />


</class>
</hibernate-mapping>

query that i hav written is:
Transaction tx=session.beginTransaction();
try{
session.save(rpd);
tx.commit();
log.info("Record successfully inserted");
flag=true;
}

please could anyone sort it out..Its urgent..
Thanks in advance.

This is the actual exception.

And it is happening coz your Id property tryCK is not having a getter setter in the Try class.

i think you are missing some setter method in the file.

i think you are missing some setter method in the file.

hi..
accordingly i modified my Try class as
package com.iwms.hibernate.JavaBeans.TEST;

public class Try {

private TryCK tryCK;
private int age;

public Try() {
tryCK = new TryCK();
}

public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}


public TryCK getTryCK() {
return tryCK;
}

public void setTryCK(TryCK tryCK) {
this.tryCK = tryCK;
}
}

But this is again giving the same error:

Yeah... That's coz the composite-id name which you have given in the mapping is "id":
<composite-id name="id"
class="com.iwms.hibernate.JavaBeans.TEST.TryCK">

make it as "tryCK"

hi..
your suggestion worked..But now i am getting other errors

I have checked the table in database too..

hi...
I sorted the problem...
thanks for your suggesstion...

Hi..
I successfully inserted the record in the database.
Now I want to update a record.I am doubtful about writing HQL query for that..
Please help..

This is the function that I have created.I have placed *****in place of query.

public String doTryUpdation(Try rpd){
String msg="";

try{
log.info("Inside Update hibernate Try Before");
TryCK obj=rpd.getTryCK();
String fname=obj.getFirstname();
String lname=obj.getLastname();
System.out.println("inside hibernate"+obj.getFirstname());
org.hibernate.Transaction tx=session.beginTransaction();
************

tx.commit();
msg="Succesfully Updated";
return msg;
}

catch(HibernateException ex) {
log.error(ex.getMessage());
ex.printStackTrace();
}
session.close();
msg="UnSuccessfull";
return msg;
}

For updation, its better to use then session methods than HQL.

May be you can do something like:

The saveOrUpdate function will generate the update queries required.

Hi..
i have updated the records.Now I have to fetch the records.
The function I have written is:

public List doTrySearch(Try rpd){
List searchResult = new ArrayList();
String fname = rpd.getTryCK().getFirstname();
String lname = rpd.getTryCK().getLastname();
System.out.println("------------> "+fname);
System.out.println("------------> "+lname);
try {
org.hibernate.Query q = session.createQuery("from Try where firstname=:fname and lastname=:lname");
q.setString("fname",fname);
q.setString("lname",lname);
searchResult = q.list();
}
catch (HibernateException e)
{
System.out.println("Hibernate Exception :"+e);
e.printStackTrace();
}
finally {
session.close();
}
return searchResult;
}
This i am using to search records but this is giving errors as:
