Hello. First, Excuse me, but my English is very bad.

I have a problem with hibernate. I have two tables with a relationship many-to-one. But when i try to get the object access at the class who makes the comp_id, it show me the next error.

ERROR: error.application.unhandled.exception

I read that the problem is the tag lazy of the hbm.cfg but i put true and false but it don´t work.

Can anybody help me?

Thanks.

You need to provide more information on what you are doing.
The error means exactly what it says. You try to access an object after the Hibernate session has been closed.

Anyway, I think you should read the documentation again, if you've already read it.

Best regards

Ok.

i need to make a comparator of the data of a table. Then i need to get all fields that compose the table.
But i don´t know what class of java file i have. then i make an abstract class of wich inherits the classes that make hibernate. These classes have a method that they inherits from the abstract class is like this:

public abstracclass getObject(Field f) {
return (abstracclass) f.get(this);
}

the java files that generates hibernate are:

class table1 class table1pk class table2
{ { {
private table1pk comp_id; private table2; String c3
private String c1; get..
private String c2; set..
get.. } }
set..
}


I´ve no problem when i try to acces to fields c1,c2 and comp_id, but when i try to get the field table2 of table1pk it give me an object that don´t belong to class table2, it is an object of type
table2$$encheritCGLIB$$ (or something like this) that have the information i need,but i can´t get it. And when i want to make something with this object, i obtain the previous error.

I hope to have explained better the problem, and again pardon by my English

Thanks.

pardon but the code is not seen well in the previous post
