Bright Zheng commented on CXF-5509:
-----------------------------------
Hi Aki,
The test case is just for service testing purpose.
While starting it up by mvn jetty:run, you can see the NPE during CXF
initialization.
As the CXF couldn't startup properly, I didn't add any test cases for Web
Service yet.
Hope it clarifies.
Regards, Bright

> Key: CXF-5509
> URL: https://issues.apache.org/jira/browse/CXF-5509
> Project: CXF
> Issue Type: Bug
> Components: Aegis Databinding
> Affects Versions: 2.7.8
> Environment: RHEL6.3 (64b), JDK1.6, Spring 3.0.6, CXF 2.7.8
> Reporter: Bright Zheng
> Labels: NPE, aegis, binding, cxf, generic
> Attachments: learning-spring_cxf.zip

> I want to expose a set of classes by setting the aegisContext:
> {code:xml}
> <bean id="aegisContext" class="org.apache.cxf.aegis.AegisContext"
> scope="prototype">
> <property name="writeXsiTypes" value="true"/>
> <property name="rootClassNames">
> <ref bean="bindingList"/>
> </property>
> </bean>
> {code}
> One of the class in the list is as a response pojo which has generic-array
> field like:
> {code:java}
> public class Subject<T extends Score>{
> ...
> private T[] score;
> //and getter/setter also
> ...
> {code}
> During the deployment phase, while debugging with the CXF code, I found that
> below codes in TypeUtil.java under cxf-rt-databinding-aegis-2.7.8.jar will
> case issue:
> {code:java}
> public static Class<?> getTypeRelatedClass(Type type) {
> Class<?> directClass = getTypeClass(type, false);
> if (directClass != null) {
> return directClass;
> }
>
> if (type instanceof ParameterizedType) {
> ParameterizedType pType = (ParameterizedType) type;
> return getTypeRelatedClass(pType.getRawType());
> }
>
> if (type instanceof GenericArrayType) {
> GenericArrayType gat = (GenericArrayType) type;
> Type compType = gat.getGenericComponentType();
> Class<?> arrayBaseType = getTypeRelatedClass(compType);
> // believe it or not, this seems to be the only way to get the
> // Class object for an array of primitive type.
> Object instance = Array.newInstance(arrayBaseType, 0);
> return instance.getClass();
> }
> return null;
> }
> {code}
> {color:red}
> Note: the arrayBaseType will always be null while initializing that class so
> it will cause the next line of code NPE!!
> {color}
> Did I miss anything for this kind of class mapping while using aegis?
