passing parameters to urls in struts2?

Question

I am working with a struts2 project and i need to pass parameters through url... this is the code that i have written

<s:url action="submit/CalculatePoints" includeParams="get" var="playerX" >
    <s:param name="winnerNo" value="player2"/>

it was refernced by following code

<a href="<s:property value="#playerX" />">

I expected that the markup for the link be

submit/CalculatePoints?winnerNo=palyer2

However iam not getting the querystring part. also attribute winnerNo in the action class is not getting populated as it should be according to How to access url parameters in struts2

Please tell me where i am going wrong?

Player2 is being evaluated not as a string but an OGNL expression simply quote Player2 and the issue will be resolved.

IE:

<s:url action="submit/CalculatePoints" includeParams="get" var="playerX" >
    <s:param name="winnerNo" value="'player2'"/>
</s:url>

+1. It was not obvious to me why it was only picking up values that were numbers and not any of the strings. Thanks so much! – Conrad.Dean Feb 20 '12 at 23:03

The struts documentation for <s:url> says this:

The includeParams attribute may have the value 'none', 'get' or 'all'

Since you set this attribute to 'true', the tag seems to be ignored. Also, you must set the escapeAmp attribute to 'false'. (I assume you have a closing </s:url> somewhere else in the code).

is the value of the property tag because the name of the url specified in the url tag's var attribute. and i thought this tag which you have written is for the pages that will be rendered using the url. i have modified the question to avoid confusion – SonOfTheEARTh Dec 21 '10 at 21:59
My bad. I actually did get confused ;) I'll edit my answer to solve your problem. – weltraumpirat Dec 21 '10 at 22:08
I've added some more info above. – weltraumpirat Dec 21 '10 at 22:31
still i am not able to get the output – SonOfTheEARTh Dec 21 '10 at 22:37
Well, you should now. I have triple-checked the documentation. Have you tried restarting your server or erasing the .class file in the server's directory for compiled JSPs? – weltraumpirat Dec 21 '10 at 22:39
