If you want to generate package depending on the namespace here is the solution:
<plugin>
<groupId>org.apache.cxf</groupId>
<artifactId>cxf-codegen-plugin</artifactId>
<version>2.6.0</version>
<executions>
<execution>
<id>generate-sources</id>
<phase>generate-sources</phase>
<configuration>
<sourceRoot>${basedir}/target/generated/src/main/java</sourceRoot>
<wsdlOptions>
<wsdlOption>
<wsdl>yourWsdl.wsld</wsdl>
<extraargs>
<extraarg>-client</extraarg>
<extraarg>-verbose</extraarg>
<extraarg>-p</extraarg>
<extraarg>http://your.namespace/services/=your.package</extraarg>
<extraarg>-p</extraarg>
<extraarg>http://your.namespace2/services2/=your.package2</extraarg>
</extraargs>
</wsdlOption>
</wsdlOptions>
</configuration>
<goals>
<goal>wsdl2java</goal>
</goals>
</execution>
</executions>
</plugin>
This <extraarg>http://your.namespace2/services2/=your.package2</extraarg>
will map your namespace with the package you want.
