How to create a parameter in JSP? I want to make a parameter of String type. Are all parameters of String type only? I have tried this:

 <% request.setAttribute("testID", "1"); %>

And this:

<% String testID="1"; %>

But on fetching value of parameter, through this:

String testID=request.getParameter("testID");

I am receiving null. How to fetch value of parameter testID? Also, what is difference between parameter and attribute?

You should start by consulting the javadoc. – Sotirios Delimanolis Oct 02 '14 at 04:29
@SotiriosDelimanolis that question, did not answered my question. How to set parameter? – Malwinder Singh Oct 02 '14 at 04:33
Read more carefully. Parameters are either submitted through a form or through the query string. – Sotirios Delimanolis Oct 02 '14 at 04:33
@SotiriosDelimanolis give me a working solution. What to write inside JSP file? – Malwinder Singh Oct 02 '14 at 04:34
Solution to what? Use a `
` and submit it or provide query strings in your request URL.

I used `
` but i am again receiving null. I used a hidden field inside it : ``. I dont want to pass the value through query String in URL. `

you can try: jstl lib as . But remember import taglib first. – Phong Nguyen Oct 02 '14 at 04:36
If you have a question about how to submit a `
` and you can't find results after doing extensive research, then ask a new question.

Thank you, however i want to ask is there any way to make hidden parameter using `
`? If yes, then how?

Put the `` inside the <`form>`. – Pradeep Kr Kaushal Oct 02 '14 at 07:46
