http:inbound-gateway not returning response

Hi,

I am using an http:inbound-gateway for processing a request on server and sending the response back to the client.
The problem is that it always returns null.
Here is my configuration:

Code:

---


<int-http:inbound-gateway id="testAdapter.htm" request-channel="testChannel" name="/testAdapter.htm" reply-channel="testGatewayChannel" supported-methods="GET" view-name="defaultJsonView"/>
        <int:service-activator ref="testConverter" input-channel="testChannel" output-channel="testGatewayChannel" />

        <bean id="testConverter" class="com.messaging.MessageReceiver" />
       
        <bean id="testSender" class="com.messaging.ReplySender"/>
       
        <int:service-activator ref="testSender" input-channel="testGatewayChannel" method="sendMessage" />

---

I even tried using chain:

Code:

---

<int:chain input-channel="testChannel" output-channel="testGatewayChannel">
                <int:service-activator ref="testConverter" />
                <int:service-activator ref="testSender" method="sendMessage" />
</int:chain>

---

But still got the same response as null.

And here is my Sender Class which sends the response

Code:

---

public class ReplySender
{
public String sendMessage(Message<?> message)
        {

                try
                {
                        System.out.println("in ReplySender sendMessage " + message.getPayload());

                       
                }
                catch (Exception e)
                {
                        e.printStackTrace();
                }
                return  message.getPayload().toString();
}
}

I am getting response as null on my client side.
Where am i going wrong?Am i using the right method?
Which is the best method for returning a response to the client?
Please help.
Thanks in advance..

Hi,

It worked.
Used the below configuration for the inboundgateway..

Code:

---


<bean id="deviceAdapter.htm" name="/adapter.htm"
                class="org.springframework.integration.http.inbound.HttpRequestHandlingMessagingGateway">
                <constructor-arg value="true" /> <!-- indicates that a reply is expected -->
                <property name="requestChannel" ref="requestChannel" />
                <property name="replyChannel" ref="responseChannel" />
                <property name="supportedMethodNames">
                        <list>
                                <value>GET</value>
                                <value>POST</value>
                        </list>
                </property>
        </bean>
