How to check if my form is being populated or not?

[Dharmendra Vishwa]

Here I am using Struts2 framework, And I want to check my form data inside <s:if> tag.

Actually i am working on upgrade and migrating application from struts to struts2. And I am figuring out the alternate of the <nsc:present> as shown in the below code. Here it is checking the form, whether it is null or not. Same thing i want to check in struts2 by using <s:if> tag.
<ncs:present name="ANC_AnnouncementAction_AnnouncementFormDetails"--> <% if(alDataOption!=null) {    for (int i=0; i < alDataOption.size(); i++)    {    } </ncs:present>
Is anyone can help me?

Welcome to CodeRanch!

I'm sorry, I don't have any experience with Struts. Maybe another member can help you out.

When you post code, please enclose it inside tags like [code]this[/code]. I will edit your post for you this time.

After formatting your code, I see some possible mistakes:

Why is there a --> at the end of the first line?

The scriptlet tag on line 2 is not terminated.

The opening brace on line 4 is not terminated.
