taglibs: how can i rewrite an action uri without rendering a html
link tag?
i need to rewrite an action uri for use in a javascript function,
something like this:
----------
function foo()
{
document.location.href=<html:link action="/foo/bar" paramId="blah"
paramName="blah"/>;
}
----------
however the <html:link> renders html code which i can't use in my
javascript function.
the <html:rewrite> tag doesnt provide support for the "action" attribute
(which, imho, renders
the "transaction" attribute useless). do i have to define an
actionforward for the action (seems like
rewrite can render an actionforward) or is there a better approach? my
application depends
heavily on javascript operations like this so i have to define an
actionforward for nearly every
single action.
thanks in advance,
art

Or, add it yourself:
package com.dotech.servlet.taglibs;
import java.net.MalformedURLException;
import java.util.Map;
import javax.servlet.jsp.JspException;
import org.apache.struts.util.RequestUtils;
import org.apache.struts.util.ResponseUtils;
public class RewriteTag extends org.apache.struts.taglib.html.RewriteTag {
public int doStartTag() throws JspException {
// Generate the hyperlink URL
Map params = RequestUtils.computeParameters(pageContext,
paramId,
paramName,
paramProperty,
paramScope,
name,
property,
scope,
transaction);
String url = null;
try {
// Note that we're encoding the & character to & in XHTML mode
only,
// otherwise the & is written as is to work in javascripts.
url = RequestUtils.computeURL(pageContext,
forward,
href,
page,
action, // The Struts 1.1 version
explicitly passes null for action
params,
anchor,
false,
isXhtml());
} catch (MalformedURLException e) {
RequestUtils.saveException(pageContext, e);
throw new JspException(messages.getMessage("rewrite.url",
e.toString()));
}
ResponseUtils.write(pageContext, url);
return (SKIP_BODY);
}
}
Then, a TLD dumped somewhere under WEB-INF in your app:
<taglib>
<tlib-version>1.0</tlib-version>
<jsp-version>1.2</jsp-version>
<short-name>dot-html</short-name>
<uri>http://dotech.com/taglibs/html</uri>
<tag>
<name>rewrite</name>
<tag-class>com.dotech.servlet.taglibs.RewriteTag</tag-class>
</tag>
</taglib>
And finally use in your JSPs:
<%@ taglib prefix="dot-html" uri="http://dotech.com/taglibs/html" %>
..
<dot-html:rewrite ...>
..

If I'm not mistaken, the "action" attribute to html:rewrite is supported
in 1.2.

I'm not entirely sure why the Struts team left out the 'action'
attribute for the html:rewrite tag, but what we've done in the
www.fiskars.com site is simply use the page attribute, appending the
'.do' manually. Certainly not as clean, and it breaks best practice, but
it works ... that's how we've gotten URLs into javascript.
