Input to a servlet

[Draug]

Hi,

I have a browser interface, using JavaScript, that recieves input from a user. When the user clicks on submit, the input is then sent to a servlet for processing.

I currently know of two ways to recieve this input.
1. Put the input as parameters in a URL for the servlet.
2. Use the Post method with the servlet to collect the values of everything on the form.

Choice 1 does not suit my needs. There are objects defined in JavaScript that I wish to use in my servlet. I want to access properties of these objects. I cannot seem to pass an object as a parameter in the URL.
Choice 2 does not suit me needs either. There are many, many values on the browser screen, and a few of them will be needed for each execution of the servlet.

What I want to do is send my JavaScript objects to the servlet. On the servlet, I want to access properties of the objects. Can I do this? If so, any ideas how? Can you point me down the right path?

Thanks for your insight,
Draug

Hey

Are all the values which you want in your servlet inside a form tag. eg. all your <input type...> etc.

If not then its better if you put all of them inside the form tag, to retrieve it in the servlet.
One more thing, can you be a more clear what the situation is where you want to access a javascript object in a servlet.Please throw some more light on this with an example if possible. Our development team wants to know more to solve your problem

thanks

Thanks for the reply

Using the post method with all of my data in a form is exactly what I have done. It works OK.

I should have made it more clear in my original post that the objects I wish to access from the clientside JavaScript are ones that I have created. I created all of my client side code using an Object Oriented methodology. What I do now is put all of the properties of each one of my objects into a form. It would be nice to keep my objects together, and use some of thier methods/attributes inside the servlet as well. As it stands now, I am rewritting the methods I need on the servlet in Java, and just pulling my values from the posted form using request.parameter.

If I can answer any more questions for you, just let me know.

Thank - you.

it is possible to read objects from the session. if you can add you object in the page to the session, u should be able to read it into the servlet as is......but i'm not sure how, if at all, it can be done directly from a web page.
