Parameters are only valid for a single request.

There are two approaches. Either use (like you have already tried) hidden fields. I think there is something wrong with your approach that didn't work because it is a valid way of processing parameters over multiple pages.

The second approach would be setting the parameters you need as a session attribute. If you carry your parameters over more than 2 pages, it can get cumbersome to always set hidden fields and then storing them in a session is the cleanest approach.

What I understand is, you are having a table with list of trains out of which you are selecting one through radio button.
If I am not wrong, then try the following code :

Create two hidden variable inside your form :




Put this structure in your table :



Now in javascript put the following code :



And now on next jsp, try to get parameter 'radioValue'.

The code is as per my needs (it is passing values servlet & futher).... So modify it to work done

Hope it may work for you ! Best Luck

Thanks
