In my jsp page i have a hyper link, a text box and an empty drop down list. On clicking hyper link a child window is open in which i can select some value and this values pass to the parent window text box and the child window closes. Now i want to do the same thing with my drop down list. I mean select some value from the child window and then show this in the drop down list. But i m not finding any solution. If any body has any idea help me. Thanks in advance.
