Hi Friends, I am facing a problem in my struts application. The scenario is : There is a screen on which I have an 'Upload' button. When use clicks this 'Upload' button, a child window opens which allows user to browse for file. There is one 'Submit' button on child window which submits the form to an Action class. After performing the desired functionality in this action, I want to close that child window. I do not know how to do this. I will be very thankful if anybody can help.
