Hi,
I found strange behavior when using chaining router with HTTP endpoints.
I'm using Mule 2.2.1 with JDK 1.6.0_10 on Windows XP and have following service configured in my model:
<service name="musicbrainz.org-service">
<inbound>
<vm:inbound-endpoint path="musicbrainz.org-service" />
</inbound>
<outbound>
<chaining-router>
<http:outbound-endpoint
address="http://musicbrainz.org/ws/1/artist/?type=xml&name=#[payload:]"
user="***" password="***" method="GET">
</http:outbound-endpoint>
<http:outbound-endpoint
address="http://musicbrainz.org/ws/1/artist/#[payload:]?type=xml&inc=sa-Album"
user="***" password="***" method="GET">
<byte-array-to-string-transformer />
<xmls:xml-to-dom-transformer
returnClass="org.w3c.dom.Document" />
<xmls:xpath-extractor-transformer
expression="/mb:metadata/mb:artist-list/mb:artist[1]/@id"
resultType="STRING">
<xmls:namespace uri="http://musicbrainz.org/ns/mmd-1.0#"
prefix="mb" />
</xmls:xpath-extractor-transformer>
</http:outbound-endpoint>
<vm:outbound-endpoint path="get-artist-info.reply" />
</chaining-router>
</outbound>
</service>
First HTTP request gets XML with some specific id, in following HTTP request I use this id (extracted from XML response) to construct next HTTP request. Everything works fine, except that second request is executed as POST, even if I set endpoint attribute to 'GET'.
Here are log entries:

I checked using debugger that MuleMessage for second HTTP request, doesn't have property HttpConnector.HTTP_METHOD_PROPERTY and is using default value:
String method = msg.getStringProperty(HttpConnector.HTTP_METHOD_PROPERTY, "POST");
Can you help me and tell me what I am doing wrong?

I checked using debugger that MuleMessage for second HTTP request, doesn't have property HttpConnector.HTTP_METHOD_PROPERTY and is using default value:
String method = msg.getStringProperty(HttpConnector.HTTP_METHOD_PROPERTY, "POST");
Can you help me and tell me what I am doing wrong?

Hi,
I found workaround for this, my new service looks like this:
<service name="musicbrainz.org-service">
<inbound>
<vm:inbound-endpoint path="musicbrainz.org-service" />
</inbound>
<outbound>
<chaining-router>
<http:outbound-endpoint
address="http://musicbrainz.org/ws/1/artist/?type=xml&name=#[payload:]"
user="jpalka" password="opunaela" method="GET" synchronous="true">
<response-transformers>
<byte-array-to-string-transformer />
<xmls:xml-to-dom-transformer
returnClass="org.w3c.dom.Document" />
<xmls:xpath-extractor-transformer
expression="/mb:metadata/mb:artist-list/mb:artist[1]/@id"
resultType="STRING">
<xmls:namespace uri="http://musicbrainz.org/ns/mmd-1.0#"
prefix="mb" />
</xmls:xpath-extractor-transformer>
</response-transformers>
</http:outbound-endpoint>
<http:outbound-endpoint
address="http://musicbrainz.org/ws/1/artist/#[payload:]?type=xml&inc=sa-Album"
user="jpalka" password="opunaela" method="GET" synchronous="true">
<byte-array-to-string-transformer />
<message-properties-transformer>
<add-message-property key="http.method"
value="GET" />
</message-properties-transformer>
<http:object-to-http-request-transformer />
</http:outbound-endpoint>
<vm:outbound-endpoint path="get-artist-info.reply" />
</chaining-router>
</outbound>
</service>
It looks like a bug for me, I just manually set http.method property:
<message-properties-transformer>
<add-message-property key="http.method"
value="GET" />
</message-properties-transformer>
<http:object-to-http-request-transformer />
But I found another issues. As you see in my chaining router I have a third endpoint,which uses VM transport to return response to async replay router:
<service name="get-artist-info">
<inbound>
<vm:inbound-endpoint path="artist" synchronous="true" />
</inbound>
<outbound>
<multicasting-router>
<!--
vm:outbound-endpoint path="last.fm-service" />
<vm:outbound-endpoint path="jamendo.com-service" /
-->
<vm:outbound-endpoint path="musicbrainz.org-service" />
<reply-to address="vm://get-artist-info.reply" />
</multicasting-router>
</outbound>
<async-reply timeout="5000">
<vm:inbound-endpoint path="get-artist-info.reply" />
<collection-async-reply-router></collection-async-reply-router>
</async-reply>
</service>
Now I get following exception:

But I found another issues. As you see in my chaining router I have a third endpoint,which uses VM transport to return response to async replay router:
