How to pass a parameter in URL on a form submit in Struts2

Question

I am doing a project in Struts2 where I need of setting a parameter in URL like user parameter in below link.

I want this parameter to be passed when I click a form submit button and not any links separately. I know how to do this with <s:url> but that way I need to create a link instead of form submit.

Can someone please help me with a code sample how to do this? I know there's a way to do it with HTML or Struts1 but how to do it with Struts2? If there is a way to do this in struts.xml, please explain with an example.

<form action="/example/xyz.action?user=george" method="POST">

Why don't you store your value in a hidden field? It will be submitted automatically , when you submit the form. — Shashank Kadne, Nov 14 '12 at 06:17
There are a lot of ways for this. Just go with the hidden field like Shashank said, it is the neatest. — Andrea Ligios, Nov 14 '12 at 08:54
Do you want this parameter to be passed every time? Or why do you want to do this in `struts.xml`? — Aleksandr M, Nov 14 '12 at 10:33
@user1819548 I was passing parameters via form actions. Is this what you needed? — Roman C, Nov 14 '12 at 23:40

try this:

<s:form action="xyz.action" method="GET">
    <s:hidden name="user" value="george"/>
    // other fields
</s:form>

method="GET" will show your parameter on the url, <s:hidden name="user" value="george"/> will take your parameter.

here is also an example for you Example

This is as close as it gets to the correct solution. See: http://stackoverflow.com/questions/1116019/submitting-a-get-form-with-query-string-params-and-hidden-params-disappear. **TLTR**: by html standards there should be no query param in action attribute of form tag. – uthomas Feb 15 '17 at 13:13
**This is not correct solution because it's missing parameters in the URL.** – Roman C Jul 01 '17 at 17:44

It's possible if you use <s:url and <s:form tags.

<%@ taglib prefix="s" uri="/struts-tags" %>

<s:url id="xyzUrl" action="xyz" includeContext="false"><s:param name="user" value="george"/></s:url>
<s:form name="xyzForm" action="%{xyzUrl}" method="POST">
