I wnat to create a collapsible/expandable tree structure using Struts in my jsp page.

How to achieve this. I am using struts 1.2.9 version.

I need a "+" sign with each parent, clicking on which the tree will collpase, "+" sign chnaging to "-" sign and show all the child nodes.The child nodes in turn will behave similar if they have any child nodes.

Thanks in advance!

Regards
Jay

I'd suggest using one of the many JavaScript tree widgets that are available. I use trees quite often in my applications, and I have downloaded and modified TreeView for this purpose. There are lots of them, though. Just Google "JavaScript tree" and you'll get an idea of what's out there.

If you have a Java data model you wish to represent as a tree structure, just write a code generator class to generate the JavaScript code that will create the tree.
