Is it like you are having a set of fields in a form in the parent window which you want to submit to the popup window?

OR

is it like you want are setting something in the request as an attributein parent window(jsp)  which you want to use in the popup(jsp)?

No.

Actually i have some objects(java beans) already in the request parameter of the parent jsp. Now i want all those Objects in my Child window so that i can use ${requestScope.mybean.value}  and display the result in the child window

thanks

You will not be able to get it directly as the popup is a new window and hence a new request object is created.

you cannot pass the bean objects through request. one way is to pass it through session, but I wouldn't suggest that. But if you the bean itsel you can pass it as session attribute but make sure that after your need you remove it from session.

If you can get the bean object using the fields in the parent window you can get that. Other wise if you just want one or two values in the bean you pass those as parameters appended to URL, to the popup window

>you have any code snippet for passing object through session in window.open

in parent window

session.setAttribute("<bean name>",<beanobject>);

in popup

session.getAttribute("<bean name>") and cast it to bean objects type

> If you can get the bean object using the fields in the parent window

say you have thje employee details in the current page like name, empid etc. and your bean like

public class EmployeeBean{

private String name;
private String id;
...
...
also you have getters and setters.
}
then when you open the popup, if the number of parameters is less and will not exceed the max url length then you can pass it them as query string and in the popup get the values from request and create a new object of the Employee and set the values

also if you are using session make sure that you do this

session.setAttribute("<bean name>",null);
so that it will not be available in the sesion nolonger
