Subject WebServiceProxyGenerator fails to handle URL
Date Mon, 16 Jun 2003 16:58:51 GMT
Trying to use WebServiceProxyGenerator I keep getting the error :
org.apache.cocoon.ProcessingException: Error invoking remote service: java.lang.IllegalArgumentException:
host parameter is null: java.lang.IllegalArgumentException: host parameter is null

With the following Stack

Original Exception: java.lang.IllegalArgumentException: host parameter is null 
at org.apache.commons.httpclient.HttpConnection.<init>( 
at org.apache.commons.httpclient.HttpConnection.<init>( 
at org.apache.commons.httpclient.SimpleHttpConnectionManager.getConnection(

I have Cocoon 2.1-m2 installed on Tomcat. The following map:generate instruction causes the
error :
      <map:match pattern="brol1">
        <map:generate type="proxy" src=""/>
        <!-- map:transform type="xslt" src="something.xsl"/-->
        <map:serialize type="html"/>

I saw in dev mailing list that there was some discussion on method selection (get or post)
. The source I have doesn't seem to take that discussion into account. Is there a recent fix
? How could I get it ?
