Hi,
I am using BeanUtils for copying the contents of one bean into another using reflection.
The code is really simple and it compiles and runs fine but does not give the desired output.
It basically *DOES NOT* copy the property 'name' from the source to the destination bean

wht cd i be doing wrong

thanks

nise



class A{

int name;

public int getName()
{

return name;

}

public void setName(int name)
{
this.name= name;
}


}

class B
{

int name;

public int getName()
{

return name;

}

public void setName(int name)
{
this.name= name;
}


}




public class test {

public static void main(String args[])
{

A a1= new A();
B b1= new B();

a1.setName(1);
System.out.println(a1.getName());
try{
BeanUtils.copyProperties(b1,a1);
System.out.println(b1.getName());
}
catch(Exception e){}

}




}
thanks ... I solved it ... it was just a minor glitch
I have 2 classes Person and Address in a one-many relatioship
One person can have many addresses

I want to write the hql equivalent for this sql query
select * from Person p ,Address a where p.id=a.id and a.add_id='103'

// this is the query that is working for me now
from Person p inner join p.addresses where p.id='1'

But now I want to be able to select based on the address primary key
thanks

Hi,

Thanks for taking the time to reply.
I have set up the Hibernate environment in Eclipse.
I have the databse drivers and have been successfully able to persist a single POJO in the database.

Where I am getting lost is the mapping part. I have not been able to find a link which gives me a clear lucid example.

I was also planning to get a copy of your book. Only thing the description of your book said that the book has not used the xml mapping files, since it is outdated.
However a lot of projects out there would most probably be still using the xml mapping files and I thought that understanding that thoroughly is important to clear one of the hibernate interviews to get into a project.

Can you refer me to a suitable example, link, book
Thanks again for all help

Hi,
Can someone save me the rigour of understanding hibernate?

I just need one working many-one mapping example, with both the xml files and the related java code.

Can someone send me a sample code or direct me to a good link or a book
Also I am unable to understand the difference between unidirectional and bidirectional mapping

I am a newbie to hibernate

Thanks
Can anyone send me a decent link showing how to integrate struts with hibernate? Just something like a helloworld application ... to help me kickstart

thanks .. i really appreciate it.

just send me any good / standard link
