I basically want to set my JSP parameters with Map values.

I am trying to do the following thing in my JSP:

<input type="hidden" name="reportSubCategories" value="<%= reportsForm.getReportSubCategories()%>" />

I know that a parameter can only be set with a String type variable and hence, the above code doesn't work.But still, is there any workaround?

Here where you have used your Map? – Girish007 Aug 24 '17 at 18:19
I am getting a return of the type Map from reportsForm.getReportSubCategories(), with which I want to set the parameter. – Saurav Ojha Aug 24 '17 at 18:26
That's not possible. If you want you can iterate through your map and create hidden input for each entry . – Girish007 Aug 24 '17 at 18:28
Are you trying to create a single hidden input field for all of the values in your map? Or one input per value? If it's one per value JSTL foreach loop would solve your problem. – BeardedDev Aug 24 '17 at 18:38
Yes !! But it's one for the entire Map value. – Saurav Ojha Aug 24 '17 at 18:49
Can you add an example of you Map? – Girish007 Aug 24 '17 at 19:16
It's nothing different. Just a normal Map with Report Sub Categories that apply to the current report. – Saurav Ojha Aug 24 '17 at 19:42
Assume it to be the most basic Map. – Saurav Ojha Aug 24 '17 at 19:42
