BPEL failed to invoke proxy server

Dear All, I tried to invoke service through the ESB using the proxy service. BPEL -> WSO2 ESB -> Endpoint service But ODE BPEL failed to invoke the proxy service. Proxy service can be accessed using soapUI. The rrrors in the logs is as follows. 13:02:13,984 1646000 DEBUG [httpclient.wire.header] (ODEServer-11:) >> "POST /services/sayHelloProxy.sayHelloProxyHttpSoap11Endpoint HTTP/1.1[\r][\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.header] (ODEServer-11:) >> "Content-Type: text/xml; charset=UTF-8[\r][\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.header] (ODEServer-11:) >> "SOAPAction: ""[\r][\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.header] (ODEServer-11:) >> "User-Agent: Axis2[\r][\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.header] (ODEServer-11:) >> "Transfer-Encoding: chunked[\r][\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.header] (ODEServer-11:) >> "Host: localhost:8280[\r][\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.header] (ODEServer-11:) >> "[\r][\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.content] (ODEServer-11:) >> "31b[\r][\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.content] (ODEServer-11:) >> "<?xml version='1.0' encoding='UTF-8'?>http://localhost:8280/services/sayHelloProxy.sayHelloProxyHttpSoap11Endpointhttp://www.w3.org/2005/08/addressing/anonymousuuid:9f617ac1-c115-4c9b-a49c-e9da5087b448-3[\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.content] (ODEServer-11:) >> " Heloo world[\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.content] (ODEServer-11:) >> "" 13:02:13,984 1646000 DEBUG [httpclient.wire.content] (ODEServer-11:) >> "[\r][\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.content] (ODEServer-11:) >> "0" 13:02:13,984 1646000 DEBUG [httpclient.wire.content] (ODEServer-11:) >> "[\r][\n]" 13:02:13,984 1646000 DEBUG [httpclient.wire.content] (ODEServer-11:) >> "[\r][\n]" 13:02:14,031 1646047 ERROR [org.apache.ode.axis2.ExternalService] (ODEServer-11:) Error sending message (mex={PartnerRoleMex#122 [PID {http://example.com/proxy/proses}proses-30] calling org.apache.ode.bpel.epr.WSAEndpoint@14c93d.sayHello(...)}): The server localhost failed to respond org.apache.axis2.AxisFault: The server localhost failed to respond at org.apache.axis2.AxisFault.makeFault(AxisFault.java:430) at org.apache.axis2.transport.http.HTTPSender.sendViaPost(HTTPSender.java:193) at org.apache.axis2.transport.http.HTTPSender.send(HTTPSender.java:75) at org.apache.axis2.transport.http.CommonsHTTPTransportSender.writeMessageWithCommons(CommonsHTTPTransportSender.java:389) at org.apache.axis2.transport.http.CommonsHTTPTransportSender.invoke(CommonsHTTPTransportSender.java:222) at org.apache.axis2.engine.AxisEngine.send(AxisEngine.java:435) at org.apache.axis2.description.OutInAxisOperationClient.send(OutInAxisOperation.java:402) at org.apache.axis2.description.OutInAxisOperationClient.executeImpl(OutInAxisOperation.java:229) at org.apache.axis2.client.OperationClient.execute(OperationClient.java:165) at org.apache.ode.axis2.SoapExternalService$1$1.call(SoapExternalService.java:199) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) Caused by: org.apache.commons.httpclient.NoHttpResponseException: The server localhost failed to respond at org.apache.commons.httpclient.HttpMethodBase.readStatusLine(HttpMethodBase.java:1976) at org.apache.commons.httpclient.HttpMethodBase.readResponse(HttpMethodBase.java:1735) at org.apache.commons.httpclient.HttpMethodBase.execute(HttpMethodBase.java:1098) at org.apache.commons.httpclient.HttpMethodDirector.executeWithRetry(HttpMethodDirector.java:398) at org.apache.commons.httpclient.HttpMethodDirector.executeMethod(HttpMethodDirector.java:171) at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:397) at org.apache.commons.httpclient.HttpClient.executeMethod(HttpClient.java:346) at org.apache.axis2.transport.http.AbstractHTTPSender.executeMethod(AbstractHTTPSender.java:550) at org.apache.axis2.transport.http.HTTPSender.sendViaPost(HTTPSender.java:189) ... 13 more 13:02:14,062 1646078 ERROR [org.apache.ode.bpel.runtime.INVOKE] (ODEServer-13:) Failure during invoke: Error sending message (mex={PartnerRoleMex#122 [PID {http://example.com/proxy/proses}proses-30] calling org.apache.ode.bpel.epr.WSAEndpoint@14c93d.sayHello(...)}): The server localhost failed to respond I hope someone can solve this problem.
