how to use part of URL as parameter

[henrik.lindberg]

Hi,
I am implementing functionality using seam where I for compatibility reasons need to pick up part of the URL and turn it into a parameter.

As an exampel - I want to treat this URL:

http://www.demo.org/service/a.b.c?param=3

as if it had been written like this:

http://www.demo.org/service.seam?func=a.b.c&param=3

The call does not come in from a browser.

How would you recommend this is implemented with seam?
(I am using Seam 1.2 and a4j/rich faces combination on JBoss EJB)

You can try to use URL Rewriter.
There are few to pick. I recommend my own :-)
http://software.softeu.cz/rewriter/

You create rewriter-config.xml and write
<rewriter-config xmlns:b="http://rewriter.softeu.cz/basic/">
<b:regex>
^/service/(.*)?param=(.*)$
/service.seam??func=$1&param=$2
</b:regex>
</rewriter-config>

And you need to add filter to web.xml

It has corrupted the content. So again :-)

<rewriter-config xmlns:b="http://rewriter.softeu.cz/basic/">
 <b:regex>
 <from>^/service/(.*)?param=(.*)$</from>
 <to>/service.seam?func=$1&param=$2</to>
 </b:regex>
</rewriter-config>

I've been using http://tuckey.org/urlrewrite/ with good results.

Thanks guys! That helped a lot!

is http://tuckey.org/urlrewrite/ working with s:link? cause HtmlLink class first encodes url and only then adds additional parameters. url rewrite filter is invoked before encoding s:link parameters (e.g., conversationId).Thanks:)
