Subject: Re: java.lang.NoClassDefFoundError exception loading a rest endPoint
in particular condition
I've done a quick local test:
@Test
public void testProxy() throws Exception {
IModel model =
JAXRSClientFactory.create("http://localhost:8080";, IModel.class);
assertNotNull(model);
model.getJsonGenericCommandDescriptor(new
GenCmdDescr("description"));
}
This throws HTTP level exception as expected, as no endpoint is
listening. The proxy is created OK. The only thing I had to remove
IPublishable from my example as you did not provide any source for it
I suspect some of your dependencies affecting the proxy generation.
Cheers, Sergey

Good morning,
the GenCmdDescr code is a class like this:
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAccessType;
@XmlRootElement(name="GenCmdDescr", namespace="http://***/";)
@XmlAccessorType(XmlAccessType.FIELD)
public class GenCmdDescr {
@XmlAttribute private String name;
@XmlAttribute private int profileId;
@XmlAttribute private int objIdHigh;
@XmlAttribute private int objIdLow;
@XmlAttribute private short protType;
public GenCmdDescr(){};
public GenCmdDescr(String name, short protType, int profileId, int
objIdHigh, int objIdLow) {
super();
this.name = name;
this.profileId = profileId;
this.objIdHigh = objIdHigh;
this.objIdLow = objIdLow;
this.protType = protType;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public int getProfileId() {
return profileId;
}
public void setProfileId(int profileId) {
this.profileId = profileId;
}
public int getObjIdHigh() {
return objIdHigh;
}
public void setObjIdHigh(int objIdHigh) {
this.objIdHigh = objIdHigh;
}
public int getObjIdLow() {
return objIdLow;
}
public void setObjIdLow(int objIdLow) {
this.objIdLow = objIdLow;
}
public short getProtType() {
return protType;
}
public void setProtType(short protType) {
this.protType = protType;
}
}
while the ws interface is similar to this (I have reported only the method with
problems):
@WebService(targetNamespace = "****")
public interface IModel extends IPublishable {
@CxfWSAuthorization(group=***, roles={***})
@GET
@Consumes({MediaType.APPLICATION_XML})
@Path("/getJsonGenericCommandDescriptor/{genericCommand}")
public String getJsonGenericCommandDescriptor(
@WebParam(name = "genericCommand") @PathParam("genericCommand")
GenCmdDescr genericCommand) throws InstantiationException;
}

Can you give me a favor and attach an interface and GenCmdDescr source
to JIRA ? Or nabble ? I'll give it a try

Thanks for the fast reply.
I do not use a concrete class and when I create the proxyFactory I use the corresponding
ws interface class as "clazz" value.

Hi at all,
I have the following problem loading a rest endPoint using cxf.
The operations I do to load the rest endPoint after its publication are the
following:
JAXRSClientFactoryBean proxyFactory = new
JAXRSClientFactoryBean();
proxyFactory.setServiceClass(clazz);
address += servName;
proxyFactory.setAddress(address);
proxy = proxyFactory.create();
.....
The "proxyFactory.create()" operation recall the "createWithValues" method
of JAXRSClientFactoryBean:
public Client createWithValues(Object... varValues) {
...
actualClient =
(Client)ProxyHelper.getProxy(Thread.currentThread().getContextClassLoader(),
new Class[]{cri.getServiceClass(),
Client.class, InvocationHandlerAware.class},
proxyImpl);
...
}
Now I have the following anomalous behavior:
the "getProxy(...)" operation fails when the ws interface contains a method
that wants a "complex" input parameter like this:
@GET
@Consumes({MediaType.APPLICATION_XML})
@Path("/getJsonGenericCommandDescriptor/{genericCommand}")
public String getJsonGenericCommandDescriptor(
@WebParam(name = "genericCommand")
@PathParam("genericCommand")
GenCmdDescr genericCommand) throws InstantiationException;
If the ws interface contains this method, an exception
"java.lang.NoClassDefFoundError: ___.GenCmdDescr" occurs loading the
endPoint.
If I remove this method from the ws interface the loading operation is right
and no exceptions occurs.
I do not understand why it happens.
In fact in the same ws interface I have another method that returns a
GenCmdDescr and no NoClassDefFoundError exception occurs with this.
The exception seems to occur only if the GenCmdDescr is used like an input
parameters of one of the methods and no excpetions occurs for method that
return an object GenCmdDescr.
Someone can help me?
Do you use a concrete class to create a proxy ? Example, do you use say
MyServiceImpl.class where MyServiceImpl is a root resource implementation ?
I can only think at the moment of CGLIB getting confused (which is used
to create a proxy when a concrete class like MyServiceImpl is proxified)
Cheers, Sergey
Thanks a lot,
Andrea
NOTE:
1.
The GenCmdDescr object is an object like this:
@XmlRootElement(name="GenCmdDescr", namespace="http://****/";)
@XmlAccessorType(XmlAccessType.FIELD)
public class GenCmdDescr {
@XmlAttribute private String name;
@XmlAttribute private int a;
@XmlAttribute private int b;
@XmlAttribute private int c;
@XmlAttribute private short d;
...
}
2.
I'm using cxf 2.5.0 version
