调用wso2 http端点时出现“ org.apache.http.nohttpresponseexception目标服务器无法响应”

Question

I am getting below error while calling http endpoint:- The endpoint is HTTP endpoint which I am using. Also added timeout parameters in axis2.xml and axis2.blocking.xml. But it did not work. Can anyone provide any solution to it?

HTTPSender Unable to sendViaPost to url[http://*********]

        at org.apache.commons.httpclient.HttpMethodBase.execute(HttpMethodBase.java:1098)

the esb proxy looks like below:--

I believe the error is printed by your http client. To fix it, do these.

1) Remove <property name="OUT_ONLY" value="true"/>

2) Add <respond/> mediator at the end of inSequence .
