Using CXF's Failover Feature
I'm trying to use the failover feature. The documentation for this seems thin; it is mentioned at http://cwiki.apache.org/CXF20DOC/featureslist.html and javadocd at http://incubator.apache.org/cxf/javadoc/latest/org/apache/cxf/clustering/pac kage-summary.html I understand that I need to enable the failover feature by supplying a failover strategy and that at runtime, the getAlternateEndpoints is invoked on my selected FailoverStrategy. Here is how I do it in my client's cxf.xml: It is not clear to me how and where I need to supply the alternate endpoints and if there is anything else I need to do for enabling CXF to look at those alternate endpoints if invocations on my webservice fail. Has anyone here used CXF's failover? -ayush

Re: @XmlJavaTypeAdapter with HashMap creates two fields on SOAP object
If you read the javadoc for the XmlAccessType class, (I just did, I
didn't realize this either), even private fields will be grabbed if they
have a JAXB annotation on them.
Thus, you might want to change to:
XmlAccessType.FIELD
to only look at the field.
Alternatively, take the @XmlJavaTypeAdapter annotation off the field and
stick it on the getter. Thus, the field won't have any jaxb
annotations on it. JAXB SHOULD allow it to work that way.

@XmlJavaTypeAdapter with HashMap creates two fields on SOAP object
One of my WebParams has a HashMap in it and so I've annotated the field with
@XmlJavaTypeAdapter and created an XmlAdapter for it. The java generated
from the WSDL has a field that's listed in that Adapter along with a
"HashMap" that extends "AbstractMap", both in my namespace.
The "HashMap" object has getters and setters based on the fieldName while
the holder object for a List of my Entries is based on the method name.
That is this class:
@XmlRootElement
public class AdRequest {
@XmlJavaTypeAdapter(QueryParametersAdapter.class)
private Map m_queryParameters;
public Map getQueryParameters() { ... }
public void setQueryParameters(Map p_queryParameters) {}
}
Turns into this after wsdl2java:
public class AdRequest implements java.io.Serializable {
private mynamespace.HashMap m_queryParameters;
private mynamespace.AdRequestQueryParametersEntry[] queryParameters;
}
Where mynamespace.HashMap extends mynamespace.AbstractMap.
Marshalling and unmarshalling works fine with my Map values
added via setQueryParameters(AdRequestQueryParametersEntry[]). I'm just
annoyed that this HashMap shows up.
I've tried to annotate with XmlAccessType set to PUBLIC_MEMBER (the default)
and PROPERTY but it hasn't helped me out.
If I change the field name in my original AdRequest to "queryParameters" I
get this error in my logs:
Class has two properties of the same name "queryParameters"
this problem is related to the following location:
at public java.util.Map
com.ladro.cxf.image.AdRequest.getQueryParameters()
at com.ladro.cxf.image.AdRequest
this problem is related to the following location:
at private java.util.Map
com.ladro.cxf.image.AdRequest.queryParameters
at com.ladro.cxf.image.AdRequest
which does make sense.
Has anyone else seen this? I've also tried marking the field as
XmlTransient but then JAXB ignores the getters and setters.

wsdl location change from 2.0.4 to 2.0.5
I tried switching from 2.0.4 to 2.0.5-20080311.140539-8,
but I have a problem with WSDLToJava. In 2.0.4 it generated
*Service.java class with a relative path like "wsdl/Tx.wsdl"
but in 2.0.5 it generates it with an absolute path like
"file:/C:/projects/trunk/bc/ws/template/wsdl/Tx.wsdl"
I tried adding the -wsdlLocation flag, and it fixed the problem
in the @WebServiceClient annotation but not in the URL defined
in the static block of the service class, which looks like this
static {
URL url = null;
try {
url = new
URL("file:/C:/projects/trunk/bc/ws/template/wsdl/Tx.wsdl");
} catch (MalformedURLException e) {
System.err.println("Can not initialize the default wsdl from
file:/C:/projects/trunk/bc/ws/template/wsdl/Tx.wsdl");
// e.printStackTrace();
}
WSDL_LOCATION = url;
}
So is this a bug in wsdl2java in 2.0.5?
If not is there a way around it?
I also get this when I startup JBoss 4.2.2 with 2.0.5.
Do I need to worry about this? What does this mean?

Re: Exception in INOUT parameter
Well, the first error is due to a bug in XmlSchema that we're TRYING to
get a fix from them for:
https://issues.apache.org/jira/browse/CXF-1388
That team hasn't been to responsive with getting us a fix though. If you
would like to bug [EMAIL PROTECTED] about it, that would be
great. The fix is in place, we just need a release from them.
A test case for the second would be good.

Exception in INOUT parameter
Hi,
I need to expose a service with CXF with an INOUT parameter. The INOUT
parameter is array of objects (of class NameAndValue_T).
The interface exposed is:
package foo;
import javax.jws.WebParam;
import javax.jws.WebParam.Mode;
@javax.jws.WebService(name="ENDPOINT_NAME",
targetNamespace="NAME_SPACE")@javax.jws.soap.SOAPBinding(use=javax.jws.soap.SOAPBinding.Use.LITERAL,
parameterStyle=javax.jws.soap.SOAPBinding.ParameterStyle.WRAPPED)
public abstract interface TestInterface {
@javax.jws.WebMethod(operationName="bar")
abstract public boolean bar(@WebParam(name="how_many") int how_many,
@WebParam(name="nameList", mode=Mode.INOUT)
javax.xml.ws.Holder nameList);
}
During the Service creation the following Exception is raised:
