CXF outbound endpoint closes stream payloads resulting in attempted read on closed stream errors

This is probably related to http://mule.mulesource.org/jira/browse/CXF-8

This should be fix in revision: http://fisheye.codehaus.org/changelog/mule/?cs=13733

Still working to verify everything is working for folks.

OK, fixed for real this time with a test case: http://fisheye.codehaus.org/changelog/mule/?cs=13737
And merged: http://fisheye.codehaus.org/changelog/mule/?cs=13741

I did some testing on 2.2-SNAPSHOT (build 13742) and got the following error after a couple of requests:

OK, I'll reopen and try to see what this other issue is.

I did some more investigating and this turned out to be because synchronous was not set to true on any of the endpoints. So you need a config like this:
<http:connector name="HttpConnector" keepAlive="true" sendTcpNoDelay="false" receiveBufferSize="0" sendBufferSize="0" />
<jetty:connector name="jettyConnector"/>

<model name="proxies">

<service name="echoProxy">
<inbound>
<cxf:inbound-endpoint address="jetty://localhost:63082/services/EchoProxy" proxy="true" synchronous="true" protocolConnector="jettyConnector">

</cxf:inbound-endpoint>
</inbound>
<outbound>
<pass-through-router>
<cxf:outbound-endpoint address="http://localhost:63081/services/Echo" proxy="true" synchronous="true" protocolConnector="HttpConnector"/>
</pass-through-router>
</outbound>
</service>

<service name="echoService">
<inbound>
<cxf:inbound-endpoint
address="jetty://localhost:63081/services/Echo" frontend="simple" synchronous="true" protocolConnector="jettyConnector"/>
</inbound>
<component class="org.mule.component.simple.EchoComponent" />
</service>

</model>

Note that I'm using the Jetty transport here. It handles overloaded connections much better than the stock HTTP transport. If the regular HTTP transport runs out of threads it ends up closing the connection. Then on the client side you'll end up with something like this:

org.apache.commons.httpclient.ProtocolException: Unbuffered entity enclosing request can not be repeated.

I would recommend that you use the jetty connector as well.

I did however uncover one other bug when I did a more thorough load testing on it. The HttpClient connections were not being released, so after a few connections everything would grind to a halt. This is fixed here:

http://fisheye.codehaus.org/changelog/mule/?cs=13745

Dan - can you clarify which version the fix made it into - 2.2?

Fixed in 2.1.4: http://fisheye.codehaus.org/changelog/mule/?cs=14443

Hi Dan,
I think this is still screwed in 2.2.1. I found this issue after posting on the dev-list.
My cxf client is running out of connections. I think the real bug is that the default value of closeInput should be true in
org.mule.transport.cxf.transport.MuleUniversalConduit

I dont know where my plain generated cxf client should use the closing interceptor

please verify whether and where this is fixed in the 2.2.x codeline

This issue has been fixed in the above versions.
