reset param values in c:url tag

[Kaylee Sebi]

Hi I am new to jsp.

I have a url variable:
<c:url var="listingBaseUrl" value="${baseUrl}/>

in ${listingBaseUrl} there is a param called "begin" and I would like to reset the value of begin in url. So I try to do :

<c:url var="listingBaseUrl">
<c:param name="begin" value="100"/>
</c:url>

This only added another param begin in the url and listingBaseUrl ended up having duplicate param begin.

I tried to do:
<c:url var="listingBaseUrl">
<c:set var="begin" value="100"/>
</c:url>

but it didn't work.

Any suggestions?

There is no way to remove a parameter already on a URL using <c:url>.

Hi I don't want to remove the parameter I just want to reset the value of the parameter. How do I do that?

[Bear Bibeault]

Replacement implies removal. Can you not make the decision which value to use before setting the parameter in the first place?

[Kaylee Sebi]

url is the request url so that is what I have to work with.

Maybe I can try string replacement? like fn:replace tag?

You should be able to reconstruct the base URL without the parameters from the information on the request.
