Parsing parameter from child windows to parent in JSP

[Chuan Ren]

I have two JSP i.e. course1.jsp and course2.jsp. I would want to find out how I could parse the parameter/value from child window to the parent window when the child window get closed.

What I am trying to do is actually a file upload process. The child windows will open for user to upload the file, and when close, the file name will be parse into the parent form for database update. Is this something possible at all? or is there any other better approaches.

Thank you.

These are the two files:

--------course1.jsp ------------

Attach File <p>
<FORM name="courseForm" action="course2.jsp" method="post" enctype="multipart/form-data">
<TABLE cellSpacing=1 cellPadding=3 border=0 WIDTH=500>    
     <TR > 
        <TD>  
        <input type="text" NAME="f_file_name" size="30" VALUE="this value should be taken from child windows">
        <a href="course2.jsp" target="new"> get file name </a>
        <p>
   <INPUT class="buttons" TYPE="submit" NAME="submit" VALUE="Submit">
       </TD>
      </TR> 
</TABLE>
</FORM>
 

---- course2.jsp -------

<%
 String filename = "this is the string needs to go back to parent windows when I click on close";
 %>
 <p>
  a close buttom
