problem with WebServiceProxyGenerator
Hello out there,
I'm developing a webapp with cocoon-2.1m2 and want to use the wsproxy. but wsproxy doesn't work, instead it throws an IllegalArgumentException "host parameter is null". the configuration is quite simple and should be correct - as far as the documentation is up to date.
<map:generator name="wsproxy" logger="webapp.wsproxy" pool-grow="2" pool-max="16" pool-min="2" src="org.apache.cocoon.generation.WebServiceProxyGenerator"/>
...
<map:generate type="wsproxy" src="http://localhost:8080/comnetSkat/login.skat">
<map:parameter name="wsproxy-method" value="POST"/>
</map:generate>
here's a snippet of the stack trace
ERROR (2003-07-01) 17:12.05:452 [access] (/comnetCocoon/login.skat) Thread-10/CocoonServlet: Internal Cocoon Problem

so, what's going wrong here? i would be glad, if anybody could give an answer.
thanks you very much in advance.

ps: I tried the HttpProxyGenerator, but this one doesn't fit my needs, because it passes only those parameters to the remote service which I configure in the sitemap - am I wrong?

It looks like a bit of stuff that the WSPG uses is currently marked as
deprecated in commons-httpclient, which could be the cause of our
problems here. I'll put working on this on my plate ASAP.

Yeah, It's looking that way :(
I've noticed posts from other people asking about this, too -- no replies.
I'm a little short on time this afternoon, I'll try to dig into it tonight after class...

Well, Looking at the source to commons-httpclient at
http://jakarta.apache.org/commons/httpclient/xref/org/apache/commons/httpclient/HttpConnection.html,
it looks like the 'host' which is being passed to the constructor is null. Obviously, it's very
strange this is happening. I'll try to dig into the WSPG code today and see if I find anything...
Does anybody know if commons-httpclient has changed recently?
