    How to do connection pooling on CXF endpoint

    Nitesh jain Newbie

         I'm using camel 2.15.3 and cxf 3.0.6

       

      I have an cxf endpoint as below in my camel context .. (TEST_ENDPOINT is an actual endpoint)
      <to uri="cxf://{{TEST_ENDPOINT}}?dataFormat=payload&amp;loggingFeatureEnabled=true" />

       

      I wanted to limit the number of HTTP connections to TEST_ENDPOINT, Tried below but it doesn't help..

       

      <bean id="http" class="org.apache.camel.component.http.HttpComponent">
                      <property name="camelContext" ref="sendSMSContext_rest" />
                      <property name="httpConnectionManager" ref="myHttpConnectionManager" />
              </bean>

       

              <bean id="myHttpConnectionManager"
                      class="org.apache.commons.httpclient.MultiThreadedHttpConnectionManager">

       

                      <property name="params" ref="myHttpConnectionManagerParams" />
              </bean>

       

              <bean id="myHttpConnectionManagerParams"
                      class="org.apache.commons.httpclient.params.HttpConnectionManagerParams">
                      <property name="maxTotalConnections" value="5" />
              </bean>

       

      according to this post http://cxf.547215.n5.nabble.com/HTTP-Connection-Pooling-td561783.html,

      CXF relies on the out-of-the-box java.net URL and HttpURLConnection, so i also tried setting up the following in my camel context xml

       

      <bean id="systemProps"

       

                    class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">

       

                    <property name="targetObject" value="#{@systemProperties}" />

       

                    <property name="targetMethod" value="putAll" />

       

                    <property name="arguments">

       

                           <util:properties>

       

                                 <prop key="http.maxConnections">10</prop>

       

                                 <prop key="Connection">close</prop>

       

                           </util:properties>

       

                    </property>

       

      </bean>

      But still i can see more than 200 Established connections, seems like there is no effect ...

       

      When i do a load test, i can see 200+ ESTABLISHED connection, though maxTotalConnections is 5 !!
      any help is appreciated.
