Subject Antwort: Re: XTags: Passing non String Parameters to a Stylesheet?
Date Fri, 23 Nov 2001 10:30:11 GMT
Hi James,

thanks for quick response and of course the patch! 

We currently use the possibility of using arbitrary Java Objects in the 
stylesheet for various reasons. One is for example that for the session 
handling we did not want to use Cookies, so we had to use url rewriting. 
The result is that all links that are generated in the stylesheet have to 
be encoded of the actual response object in order to append the session 
id:

<xsl:param name="response"/>

......
<a>
        <xsl:attribute name="href">
                <xsl:value-of select="java:encodeURL($response, 
'a_link')"/>
....

Thanks also for the JSTL hint. I haven't recognized it yet. Especially the transformer tag
seems 
to be valuable for me because I have exactly the problem of using the same 
stylesheets over and over again.

Regards -- Tobias

Hi Tobias

The parameters values were Stirngs. I've just patched the code so that any
object can be passed in to the XSLT engine. This fix will make it into the
next nightly build.

Though whether the XSLT engine is capable of using other types of
parameters, such as HttpServletResponse, is questionable. Certainly 
handling
DOM Nodes or Numbers is possible. In what way to you want the XSLT engine 
to
use the HttpServletResponse?

BTW the standard tag library, JSTL, now has XML tags which are based 
heavily
on XTags and will ultimately will supercede them. It could well be worth
taking a look at them; the original XTags design has been refined somewhat
in the JSTL XML tags.
