webservice proxy question
I am trying to use the webservice proxy to access a webservice that I
have made available using Apache Axis.
Here is the section of the sitemap that I have defined, does this look
correct to everyone?
<map:pipeline>
<map:match pattern="forms.html">
<map:generate type="proxy"
src="http://localhost:8080/axis/services/IntelligentForm?method=getForms"
/>
<map:transform src="transforms/forms.xslt"/>
<map:serialize type="html"/>
</map:match>
</map:pipeline>
However I get the following error when attempting to run it:
Original Exception: java.lang.IllegalArgumentException: host parameter is null
at org.apache.commons.httpclient.HttpConnection.<init>(HttpConnection.java:227)
at org.apache.commons.httpclient.SimpleHttpConnectionManager.getConnection(SimpleHttpConnectionManager.java:115)
at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:548)
at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:476)
When I access the webservice through a web-browser I get
<soapenv:Envelope>
<soapenv:Body>
<getFormsResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<GetFormsReturn xsi:type="xsd:string"><Forms><Form>FormA</Form><Form></GetFormsReturn>
</getFormsResponse>
</soapenv:Body>
</soapenv:Envelope>
I access through a proxy server, but I have set JAVA_OPTS to be
-Dhttp.proxyHost=hellman -Dhttp.proxyPort=8080 -Dhttp.nonProxyHosts=localhost
before starting up Tomcat.
Can anyone thing of what the problem may be?
Thanks in advance,
Pete

Follow the link to bugzilla from the cocoon.apache.org site and file it
as a "bug" with the summary
starting with [PATCH].

How do I submit it as a patch?
I am also working on handling http.nonProxyHosts at least semi-correctly
as I need to access web-services both inside and outside the firewall at
my work.

Well, looks like you're ahead of me.. this look good.. can anyone else confirm this works (like
anyone else who was posting to the list about the WSPG) ?
Pete, would you mind submitting this as a patch? Perhaps we can slip this in before 2.1 goes final.

The following patch works for me, but note that there is still an
unresolved problem with the fact that we don't parse http.nonProxyHosts
to ensure that proxying is only enabled for connections which need it.

Pete,
See this thread in the message archive, it is a known problem and I'm working on tracking down the
problem.
