Thanks very much, it works! It helped me to avoid converting hierarchical structure to linear table!

@Gabor: I think you did something wrong. You shouldn’t get an endless loop exactly because ‘node’ is overwritten.

this stuff does not work
you get and endless loop because ‘node’ gets overwritten in the inner loop

Thanks for your post on JSP recursion. This is exactly what I was looking for. I needed to generate a tree structure for DHTML flyout menus. I had resigned myself to having to generate the desired html in a custom tag. But the downside to this approach is embedding html in Java and taking the maintenance of the navigation style out of my designer’s hands and placing it in my own. This solution is much more elegant by keeping the html where it belongs.

That’s right. I think this is the only possibility to reuse parts of jsp code. You can reuse chunks of generated HTML defining variables with c:set, but not JSP.

Thanks for this – you could do with updating your example to use camel case c:forEach

Hi.

I’m a newbie to J2EE. Could you explain what do you mean by “redefine the variables you need in the “request” scope”? I have a tree structure which i like to show. Does it mean that i have to fetch the tree structure for every call of node.asp? Or can I “hand over” the (sub)tree structure to each node.jsp?

hi,

if i want to use your code does that mean I need to create a jsp just to house this code and then make my main jsp call this jsp ?
