Consuming a Webservice Using Mule 3.4 - web-services

Question

I am trying to consume a webservice produced on by following the tutorials in the mule Documentation. have been able to build the webservice successfully, but having issues consuming it. I have two Java Clasess "HelloWorld" and "HelloWorldImpl". This is my flow
<flow name="helloService" doc:name="helloService">
<http:inbound-endpoint address="http://localhost:63081/hello" exchange-pattern="request-response" doc:name="HTTP">
<cxf:jaxws-service serviceClass="com.test.HelloWorld"/>
</http:inbound-endpoint>
<component class="com.test.HelloWorldImpl" doc:name="Java"/>
<cxf:jaxws-client serviceClass="com.test.HelloWorld" operation="sayHi" doc:name="SOAP" />
<outbound-endpoint address="http://localhost:63081/services/greeter" doc:name="Generic"/>
</flow>
What am I doing wrong?
When I access the outbound endpoint I get
Cannot bind to address "http://activate.adobe.com:63081/services/greeter" No component registered on that endpoint

Answer 1

You have to make your endpoint accept all sub-paths and then handle wrong ones with message routing:
Example:
<flow name="jfeed_fill_data">
<http:inbound-endpoint address="http://localhost:1212" />
<choice>
<when evaluator="header" expression="INBOUND:http.request.path=/jcore/insert/feed/">
<component class="main.java.com.joshlabs.jcore.Feed"/>
</when>
<otherwise>
<message-properties-transformer>
<add-message-property key="http.status" value="404"/>
</message-properties-transformer>
<expression-transformer>
<return-argument evaluator="string" expression="{Exception: "Invalid URL"}"/>
</expression-transformer>
</otherwise>
</choice>
</flow>

First issue: How can there be two services running on the same port (63081) on your localhost.
http://localhost:63081/hello
http://localhost:63081/services/greeter
Also As mentioned in your post, the web-service you have created is Hello service with the endpoint
http://localhost:63081/hello
So you web sevice should be as follows.
<flow name="helloService" doc:name="helloService">
<http:inbound-endpoint address="http://localhost:63081/hello" exchange-pattern="request-response" doc:name="HTTP">
<cxf:jaxws-service serviceClass="com.test.HelloWorld"/>
</http:inbound-endpoint>
<component class="com.test.HelloWorldImpl" doc:name="Java"/>
</flow>
In order to consume you can write another flow which has got the cxf:jaxws-client
<flow name="helloclient" >
<some inbound endpoint. >
....
<cxf:jaxws-client serviceClass="com.test.HelloWorld" operation="sayHi" doc:name="SOAP" />
<outbound-endpoint address="http://localhost:63081/hello" doc:name="Generic"/>
.....
</flow>
Hope this helps.

Your inbound endpoint is http://localhost:63081/hello which is the address you should call to consume your webservice.
Also your outbound endpoint seems to point to a address where there is no webservice to consume. Unless you have a second flow in your mule config that you do not show.

Answer 4

You've defined a flow which has a listener on service end-point http://localhost:63081/hello. In this flow request comes in and then it is forwarded using jaxws-client to another service listening at http://localhost:63081/services/greeter.
Now the error message says Cannot bind to address which means it cannot call the end-point. Is there a service running anywhere at the end-point you're trying to send request to? If you want to send request locally as look like from your flow, then you need another flow listening at that end-point similar to one you have but with different http-endpoint
