[jira] [Created] (CXF-3581) CXF JAX-RS Client Null Pointer
Exception
CXF JAX-RS Client Null Pointer Exception
----------------------------------------
Key: CXF-3581
URL: https://issues.apache.org/jira/browse/CXF-3581
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 2.4
Environment: Apache Maven 3.0.3 (r1075438; 2011-02-28 09:31:09-0800)
Maven home: C:\Program Files\apache-maven-3.0.3\bin\..
Java version: 1.6.0_23, vendor: Sun Microsystems Inc.
Java home: C:\Program Files (x86)\Java\jdk1.6.0_23\jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows 7", version: "6.1", arch: "x86", family: "windows"
Reporter: Shaun Elliott
I am trying to use the Apache CXF JAX-RS Client API code found http://cxf.apache.org/docs/jax-rs-client-api.html#JAX-RSClientAPI-ProxybasedAPI. However, when I run the client it throws this:
{code}
Exception in thread "main" java.lang.NullPointerException
at java.util.HashMap.<init>(HashMap.java:223)
at org.restlet.ext.jaxrs.internal.core.ResponseBuilderImpl.clone(ResponseBuilderImpl.java:126)
at org.restlet.ext.jaxrs.internal.core.ResponseBuilderImpl.clone(ResponseBuilderImpl.java:62)
at org.apache.cxf.jaxrs.client.AbstractClient.setResponseBuilder(AbstractClient.java:374)
at org.apache.cxf.jaxrs.client.ClientProxyImpl.handleResponse(ClientProxyImpl.java:451)
at org.apache.cxf.jaxrs.client.ClientProxyImpl.doChainedInvocation(ClientProxyImpl.java:445)
at org.apache.cxf.jaxrs.client.ClientProxyImpl.invoke(ClientProxyImpl.java:177)
at $Proxy12.foo(Unknown Source)
at com.paml.JaxTestClient.main(JaxTestClient.java:20)
{code}
This is my client:
{code}
public class JaxTestClient {
public static void main( String[] args ) {
// Works with Restlet API - but paths are not mapped automatically
// JaxExampleEcho jaxExampleEcho = ClientResource.create( "http://localhost:8111/", JaxExampleEcho.class );
JaxExampleEcho jaxExampleEcho = JAXRSClientFactory.create( "http://localhost:8111/", JaxExampleEcho.class );
System.out.println( jaxExampleEcho.foo() );
System.out.println( jaxExampleEcho.bar() );
System.out.println( jaxExampleEcho.baz() );
}
}
{code}
And here is my interface:
{code}
@Path( "/" )
public interface JaxExampleEcho {
@GET
@Path( "foo" )
@Produces( "text/plain" )
String foo();
@GET
@Path( "bar" )
@Produces( "text/plain" )
String bar();
@GET
@Path( "baz" )
@Produces( "text/plain" )
String baz();
}
{code}
I can see the requests hitting the right url server side.

[jira] [Resolved] (CXF-3581) CXF JAX-RS Client Null Pointer

Shaun Elliott resolved CXF-3581.
--------------------------------
Resolution: Invalid
The problem was not CXF, but rather the JAX-RS restlet extension being on my path. Removing all restlet dependencies fixed the issue.
