Description

Hi Team,

  We are in the process of upgrading to latest apache-cxf framework , We use cxf in combination with google protocol buffer. I have update the cxf dependencies to 3.3.0

and using the latest following dependency

<dependency>
<groupId>com.google.protobuf</groupId>
<artifactId>protobuf-java</artifactId>
<version>3.6.1</version>
</dependency>

<dependency>
<groupId>com.google.protobuf</groupId>
<artifactId>protobuf-java-util</artifactId>
<version>3.6.1</version>
</dependency>

The current dependency on cxf-protobuf is as follows

<dependency>
<groupId>com.google.code.cxf.protobuf</groupId>
<artifactId>cxf-protobuf</artifactId>
<version>0.3</version>
</dependency>

Spring framework version is

5.1.3.RELEASEException-trace.txt

 

Looking at the exception trace that i am getting i should be going for an higher version of  cxf-protobuf dependency .i didn't find any higher version of the above dependency in any maven repository. Can you please guide me where or how can i get the higher version , also is protobuf-java supported with CXF anymore.

Attached the stacktrace

  The exception happens here in the class

// code placeholder

package com.google.code.cxf.protobuf.ProtobufQueryHandler

// code placeholder
@PostConstruct
void registerWithQueryHandlerRegistry() {
QueryHandlerRegistry queryHandlerRegistry = (QueryHandlerRegistry)this.bus.getExtension(QueryHandlerRegistry.class);
queryHandlerRegistry.registerHandler(new ProtobufQueryHandler());
}

When the bus tries to getExtension of QueryHandlerRegistry it fail and returns null causing nullpointer Exception.

 

// code placeholder
<bean id="cxf" class="org.apache.cxf.bus.CXFBusImpl">
    <property name="inInterceptors">
        <list>
            <ref bean="logInbound"/>
        </list>
    </property>
    <property name="outInterceptors">
        <list>
            <ref bean="logOutbound"/>
        </list>
    </property>
    <property name="outFaultInterceptors">
        <list>
            <ref bean="logOutbound"/>
        </list>
    </property>
</bean>

 

You can also guide me how to register extension for the bus in xml configuration .Currently the configuration is as follows
