Passing table as parameter to next page(JSTL)

[Raj Puri]

I have on first page a table object with data. When this page calls another page how do I retrieve the content of this table in next page as parameters. I am using JSTL.

[Adeel Ansari]

Are you talking about HTML Table?

[Raj Puri]

Yes. On first JSP I have a table HTML table(5 cols and 100 rows) with data.I submit this page in the next page I want to retrieve them using JSTL.

The only way you could do that is to send the table's data to the next page via HTML form elements.

Better yet, why not just re-create the data that you sent to the first page in order to create the table in the first place?

[Raj Puri]

The application current architecure passes data between pages using JSTL. The objects are retrieved using JSTL ${param}. So far only HTML <form> elements are passsed on - i can access each element like ${param.cust_name}, where cust_name is a text item in the form tag on the first page. Now if I put a table in <FORM> element how will I access individual row/cols using JSTL?

[Bear Bibeault]

Again, any data you wish to pass on to the next page must be in a form element such as <input>.

[Raj Puri]

Yes. But How do I retrive that in JSTL.Like i have a table of 10 rows and 2 columns. Syntax to retrieve that in next page?

<table rows=10>
<td>
<input type=text name="col1">
<input type=text name="col2">
<td>
</table>

Thanks

it will look like this,

request.getParameter("col1");
request.getParameter("col2");

First, a terminology correction. You mean EL not JSTL.

And the answer is just like any other submitted parameter: via the param builtin variable. E.g. ${param.col1}.

I'm not sure what's confusing you here. Just because your form elements are arranged in a table in the originating HTML form makes no difference to anything, Upon submission, all request parameters just become a map of name/value pairs.
