Elias Dorneles commented on CXF-3377:
-------------------------------------
I have this same issue happening with an app, and spent some time debugging it.
I think that, in my case, the problem is that ClientProxyFactoryBean calls
configureObject() early in create() method, but I'm not familiar enough with
CXF code to understand how all of this works...
I don't know if this is the case with the OP, but in my case, I am creating
Spring beans for the WebService clients in a Spring XML config file that goes
like this:
{noformat}

<cxf:bus />
<!-- service factory that will be shared by the WS proxy factories -->

<bean id="myService" class="package.of.MyService"

</beans>
{noformat}
This works perfectly fine using cxf-2.3.2, but fails with NPE using cxf-2.3.3:
{noformat}
Caused by: java.lang.NullPointerException
at
org.apache.cxf.jaxws.JaxWsProxyFactoryBean.getConfiguredName(JaxWsProxyFactoryBean.java:73)
at
org.apache.cxf.frontend.ClientProxyFactoryBean.configureObject(ClientProxyFactoryBean.java:99)
at
org.apache.cxf.frontend.ClientProxyFactoryBean.create(ClientProxyFactoryBean.java:120)
{noformat}
I created a simple project to verify this, I can provide it if necessary, but I
only tested it against an internal-use-only WebService.
But here are the dependencies of it (except the JAR containing the interface of
the WS):
{noformat}
aopalliance.jar
commons-logging-1.1.1.jar
cxf-2.3.3.jar (this gives the NPE, but with cxf-2.3.2.jar it works)
neethi-2.0.4.jar
org.springframework.aop-3.1.1.RELEASE.jar
org.springframework.asm-3.1.1.RELEASE.jar
org.springframework.aspects-3.1.1.RELEASE.jar
org.springframework.beans-3.1.1.RELEASE.jar
org.springframework.context-3.1.1.RELEASE.jar
org.springframework.context.support-3.1.1.RELEASE.jar
org.springframework.core-3.1.1.RELEASE.jar
org.springframework.expression-3.1.1.RELEASE.jar
org.springframework.oxm-3.1.1.RELEASE.jar
org.springframework.transaction-3.1.1.RELEASE.jar
org.springframework.web-3.1.1.RELEASE.jar
org.springframework.web.servlet-3.1.1.RELEASE.jar
wsdl4j-1.6.2.jar
XmlSchema-1.4.7.jar
{noformat}
...and here is the main class:
{noformat}
package springcxftest;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class TestApp {
private ApplicationContext context;
public void init() {
context = new ClassPathXmlApplicationContext(
"classpath:/appContext.xml");
}
public static void main(String[] args) {
TestApp app = new TestApp();
app.init();
System.out.println("App initialized");
}
}
{noformat}
Using cxf-2.3.3, it will throw the Exception and never get to the "App
initialized" message.
I hope this helps to clarify the problem!
