Hi All,
Found the cause for most. Still an odd error though. So here is the cause:
The service explicitely says @Consumes("text/xml") , while my client
specified:
RequestEntity re = new FileRequestEntity(
new File("somefile.txt"),
"application/xml; charset=ISO-8859-1");
After changing this to text/xml. POST and DELETE succeeded.
Remaining issue:
1. Why was no exception thrown?
2. Why did it revert to GET?
3. PUT still requires that basic authentication, although I would be
checking with our SysAdmin. I think this would be server specific.

Hi Team,
Sorry this would be a bit lengthy. Just want to put everything needed
to debug this available. I would summarize the issue later in the end
of the post.
I have the following class declaration:
@WebService(name="MyService",
targetNamespace="http://some.domain.com/";)
@SOAPBinding(use=Use.LITERAL, style=Style.RPC)
@Consumes("text/xml")
@Produces("text/xml")
@Path("/MyService")
public interface MyService {
@DELETE
@Path("/")
@WebMethod
@WebResult(name="count")
public int deleteMyObject(
@QueryParam("objectID")
@WebParam(name="objectID")
long objectID,
@QueryParam("comment")
@WebParam(name="comment")
String comment
);
@GET
@Path("/")
@WebMethod
@WebResult(name="check")
public boolean check();
@GET
@Path("/")
@WebMethod
@WebResult(name="objectInstance")
public WSMyObject getMyObject(
@QueryParam("objectID")
@WebParam(name="objectID")
long objectID);
/*-
* This method intentionally has no HTTP Method annotation.
* This method will be used for sub-resource locator feature

*/
@Path("/")
@WebMethod(exclude=true)
public WSMyObject getMyObjectProperty(
@QueryParam("objectID")
long objectID
);
@PUT
@Path("/")
@WebMethod
@WebResult(name="objectID")
public long insertMyObject(
@WebParam(name="objectInstance")
@FormParam(value="objectInstance")
WSMyObject objectInstance,
@QueryParam("comment")
@WebParam(name="comment")
String comment
);
@POST
@Path("/")
@WebMethod
@WebResult(name="count")
public int updateMyObject(
@WebParam(name="objectInstance")
@FormParam(value="objectInstance")
WSMyObject objectInstance,
@QueryParam("comment")
@WebParam(name="comment")
String comment
);
}
@XmlType(name="MyObject", namespace="http://some.domain.com";)
@XmlAccessorType(XmlAccessType.PROPERTY)
@XmlRootElement(name="MyObject", namespace="http://some.domain.com";)
public class MyObject{
//some delegate methods here..
}
Generated WADL is as follows:
<resource path="/MyService">
<method name="DELETE">
<request>
<param name="objectID" style="query" type="xs:long" />
<param name="comment" style="query" type="xs:string" />
</request>
<response>
<!-- Primitive type : xs:int -->
<representation mediaType="text/xml" />
</response>
</method>
<method name="GET">
<request>
<param name="objectID" style="query" type="xs:long" />
</request>
<response>
<representation mediaType="text/xml" element="prefix1:MyObject" />
</response>
</method>
<method name="PUT">
<request>
<representation mediaType="text/xml">
<param name="objectInstance" style="query" />
<param name="comment" style="query" type="xs:string" />
</representation>
</request>
<response>
<!-- Primitive type : xs:long -->
<representation mediaType="text/xml" />
</response>
</method>
<method name="POST">
<request>
<representation mediaType="text/xml">
<param name="objectInstance" style="query" />
<param name="comment" style="query" type="xs:string" />
</representation>
</request>
<response>
<!-- Primitive type : xs:int -->
<representation mediaType="text/xml" />
</response>
</method>
</resource>
If I remove @FormParam the annotation the WADL gets adjusted as follows:
<method name="PUT">
<request>
<representation mediaType="text/xml">
<representation mediaType="text/xml" element="prefix1:MyObject"/>
<param name="comment" style="query" type="xs:string" />
</representation>
</request>
<response>
<!-- Primitive type : xs:long -->
<representation mediaType="text/xml" />
</response>
</method>
<method name="POST">
<request>
<representation mediaType="text/xml">
<representation mediaType="text/xml" element="prefix1:MyObject"/>
<param name="comment" style="query" type="xs:string" />
</representation>
</request>
<response>
<!-- Primitive type : xs:int -->
<representation mediaType="text/xml" />
</response>
</method>
Issue #1: Why is the style set to query with the @FormParam
annotation? Shouldn't it be of type request or body? Basing my
thoughts from
http://jackson.codehaus.org/javadoc/jax-rs/1.0/javax/ws/rs/FormParam.html

I try to invoke updateMyObject with the following xml as payload:
POST /some/path/MyService?comment=test HTTP/1.1
User-Agent: Jakarta Commons-HttpClient/3.1
Content-Length: 2979
Content-Type: application/xml; charset=ISO-8859-1
Host: localhost:8080
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<objectInstance xmlns="http://some.domain.com";>
<objectID>2589</objectID>
<!-- other fields go here -->
</objectInstance>
Issue #2: The method being invoked is check(). It seems there is some
failure with regards to unmarshalling of the payload and it defaults
to GET?
Issue #3: I removed check(). The method being picked up now is
getMyObjectProperty() even if the queryParameter objectID is not present.
I try to invoke insertMyObject with the following xml as payload:
PUT /some/path/MyService?comment=test HTTP/1.1
User-Agent: Jakarta Commons-HttpClient/3.1
Content-Length: 2979
Content-Type: application/xml; charset=ISO-8859-1
Host: localhost:8080
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<objectInstance xmlns="http://some.domain.com";>
<objectID>2589</objectID>
<!-- other fields go here -->
</objectInstance>
Issue #4: I am expecting a 401 challenge with Digest as
authentication. I have an interceptor for this. I am 100% sure that
the word "basic" never occurs in the code, but I get this:
HTTP/1.1 401 Unauthorized
Server: Sun-ONE-Web-Server/6.1
Date: Fri, 22 Jan 2010 10:02:28 GMT
Content-length: 223
Content-type: text/html
WWW-authenticate: Basic realm="Sun ONE Web Server"
I am using iPlanet as server. It seems something else is processing
the transaction, although I cannot pinpoint yet which.
Issue #5: Reordering the parameters does not affect the behavior for
#2-4. Removing the comment parameter does not affect behavior.
Issue #6: Removing getMyObjectProperty() shows that the request is not
mapped properly. I get the following exception:
javax.ws.rs.WebApplicationException
at
org.apache.cxf.jaxrs.utils.JAXRSUtils.findTargetMethod(JAXRSUtils.java:375)
at
org.apache.cxf.jaxrs.interceptor.JAXRSInInterceptor.processRequest(JAXRSInInterceptor.java:179)
at
org.apache.cxf.jaxrs.interceptor.JAXRSInInterceptor.handleMessage(JAXRSInInterceptor.java:63)
I could be missing something simple. I just find it odd during my
initial testing the part where there is just the complex object as
parameter, this worked. From there, I added the Digest interceptor and
the second paramter. Now, removing both and I still get the exception.
It is also a bit disturbing why the POST as posted above goes to other
methods which were explicitly stated to map only to GET.
Please advise if there are other info that is needed. Thanks in advance.
