[jira] Created: (CXF-2585) Already connected exception when using a
proxy created with JAXRSClientFactory
Already connected exception when using a proxy created with JAXRSClientFactory
------------------------------------------------------------------------------
Key: CXF-2585
URL: https://issues.apache.org/jira/browse/CXF-2585
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 2.2.5
Environment: JDK 1.5.0.18
Reporter: Stephane Allegro
I'm trying to get a very simple Rest client working, but I always got this exception:
java.lang.IllegalStateException: Already connected
at java.net.HttpURLConnection.setFixedLengthStreamingMode(HttpURLConnection.java:100)
at org.apache.cxf.transport.http.HTTPConduit$WrappedOutputStream.thresholdNotReached(HTTPConduit.java:1885)

at $Proxy16.doSomething(Unknown Source)
at com.francetelecom.resttest.RestTest.main(RestTest.java:27)
Here is my jax-rs interface:
@Path("/")
public interface RestWS {
@POST
@Path("/test")
public String doSomething( @QueryParam("param") String paramName);
}
And here the way my client uses it:
RestWS proxy = JAXRSClientFactory.create("http://localhost:8080/RestWSMock",RestWS.class);
proxy.doSomething("bob");
I can not get it simpler. Any idea what's wrong ?

---------------------------------------
Hi,
here is the code for a custom interceptor :
public class EmptyPostOutInterceptor extends AbstractPhaseInterceptor<Message> {
public EmptyPostOutInterceptor() {
super(Phase.PRE_MARSHAL);
}
public void handleMessage(Message message) throws Fault {
if ("POST".equals(message.get(Message.HTTP_REQUEST_METHOD))) {
message.put("org.apache.cxf.post.empty", true);
}
}
}
you can register it from Spring like this, assuming you use jaxrs:client :
<jaxrs:client>
<jaxrs:outInterceptors>
<bean class="org.custom.EmptyPostOutInterceptor"/>
</jaxrs:outInterceptors>
</jaxrs:client>
Here is a Java code :
@Test
public void testEmptyPostProxy() throws Exception {
JAXRSClientFactoryBean bean = new JAXRSClientFactoryBean();
bean.setAddress("http://localhost:9080");
bean.setResourceClass(BookStore.class);
bean.getOutInterceptors().add(new EmptyPostOutInterceptor());
BookStore store = bean.create(BookStore.class);
store.emptypost();
assertEquals(204, WebClient.client(store).getResponse().getStatus());
}
give it a try please and let me know how it goes.
It is really a temp measure, the fix will be in 2.2.6 (to be released possibly in Jan)

Sergey Beryozkin commented on CXF-2585:
---------------------------------------
Hi,
@Path("/webform.html?cmd=execute")
identifies the value for the uri path component, so '?' and '=' have to be encoded. JAXRS does not provide for embedding query values inside a @Path annotation
How is the service endpoint written ? Is it a 3rd-party endpoint or is it yourself who wrote it ? If yes then may be that service endpoint can be updated to default to "execute" if no "cmd" query is provided ?
Another option to try is to change your method signature like this :
String createCustomer(@QueryParam("") QueryBean bean);
public class QueryBean {
private String cmd = "execute";
private String workflow;
public QueryBean() {
this("defaultWorkflowValue")
}
public QueryBean(String workflow) {
this.workflow = workflow;
}
public void setCmd(String value) {
cmd = value;
}
public String getCmd() {
return cmd;
}
public void setWorkflow(String value) {
workflow = value;
}
public String getWorkflow() {
return workflow;
}
}
and then
proxy.createCustomer(new QueryBean("SomeWorkflowValue"));
This option is good in that you can add a support for new queries by updating the query bean and the service implementation but without changing the signature
Finally, you can try to do
@Path("/webform.html")
public String createCustomer(@QueryParam("workflow") String workflow);
But then update Message.REQUEST_URI value on the current message in the CXF out interceptor, by appending "&cmd=execute" to it
hope it helps, Sergey

Sergey Beryozkin commented on CXF-2585:
---------------------------------------
it is a bug affecting a proxy based flavor only.
The problem is that a proxy does not indicate to the transport-level HttpConduit that an empty POST (with no request body) is coming which is something that never occurs with SOAP proxies.
It will be fixed for soon to be released 2.2.6
Couple of workarounds.
1. Use WebClient :
Response r = WebClient.create(endpointAddress).query("param", "bob").post(null); String s = (String)r.getEntity();
2. If you do prefer to use a proxy then for the empty POST be processed correctly, you can temporarily register a CXF out interceptor with a proxy and set a "org.apache.cxf.post.empty" property on a message - let me know please if you'd like to try this option and I will post a code for the interceptor
thanks

Hello,
Sorry, you're completly right.
I was using this annotation
@Path("/webform.html?cmd=execute&workflow=createAccount") for a method.
And CXF did escape "?" and "&" characters and that's why my endpoint was
not responding.
BTW, is there a way to force a queryparam (that always has the same
value, like the "cmd=execute" above) for a method, such as it is not a
customizable parameter of this method ?
Thanks

---------------------------------------
it is a bug affecting a proxy based flavor only.
The problem is that a proxy does not indicate to the transport-level HttpConduit that an empty POST (with no request body) is coming which is something that never occurs with SOAP proxies.
It will be fixed for soon to be released 2.2.6
Couple of workarounds.
1. Use WebClient :
Response r = WebClient.create(endpointAddress).query("param", "bob").post(null); String s = (String)r.getEntity();
2. If you do prefer to use a proxy then for the empty POST be processed correctly, you can temporarily register a CXF out interceptor with a proxy and set a "org.apache.cxf.post.empty" property on a message - let me know please if you'd like to try this option and I will post a code for the interceptor
thanks

[jira] Commented: (CXF-2585) Already connected exception when using
a proxy created with JAXRSClientFactory
Posted by "S.Allegro (JIRA)" <ji...@apache.org>.

S.Allegro commented on CXF-2585:
--------------------------------
Hi,
Yes, that's what I meant: Having "cmd=execute" by default, without having to put it in the signature.
I tried something like this:
@Path("/")
@Produces("application/xml")
public interface FlexibleHostingService {
@POST
@Path("/webform.html?cmd=execute")
public String createCustomer(@QueryParam("workflow") String workflow);
}
But this proxy escaped '?' and '=', thus posting to a non-existing endpoint.
Regards,
Stéphane

Sergey Beryozkin commented on CXF-2585:
---------------------------------------
Hi,
do you mean making it such that a proxy adds this
'cmd=execute' pair by default ?
It is not really possible with the proxy based api ? Or may be I've misunderstood the question ? What exactly you'd like to see happening ?
Perhaps the interface can be updated such that this Query param is not even in the signature ?
cheers, Sergey

Sergey Beryozkin commented on CXF-2585:
---------------------------------------
Perhaps the remote endpoint is now returns an error or not responding ?
Can you capture please what happens on the wire ?
Suppose an enpoint is listening on somehost:8080, you can use a tool like http://www.pocketsoap.com/tcptrace/ (Windows) or similar, tell it to listen on localhost:8081 and redirect to somehost:8080 and then create a client using a 8081 port...
