Title: RE: Axis2 Spring Integration, Problems using

I found a solution that works... If you follow the instructions for Axis2-Spring integration you will have a class called SpringInit.  If you look at the code below, it gets the context classloader, saves a reference to it, sets the context classloader with the deployment classloader, loads the spring config files then sets the context classloader back to the webapp classloader.  Seems to work fine.

public class SpringInit implements Service {
       
    public static final String SPRING_CONTEXT_FILE_NAMES = "springContextFileNames";
   
    private static Log logger = LogFactory.getLog(SpringInit .class);

    // The web service
    public OMElement springInit(OMElement ignore) {

        return null;
    }

    public void init(ServiceContext serviceContext) {
       
    }

    public void setOperationContext(OperationContext arg0) {

    }

    public void destroy(ServiceContext arg0) {

    }

     /**
     * this will be called during the deployement time of the service. irrespective
     * of the service scope this method will be called
     */
    public void startUp(ConfigurationContext ignore, AxisService service) {

        ClassLoader contextCl = Thread.currentThread().getContextClassLoader();
        ClassLoader classLoader = service.getClassLoader();
        Thread.currentThread().setContextClassLoader(classLoader);
        String[] springContextFiles = getSpringContextFileNames(service.getParameter(SPRING_CONTEXT_FILE_NAMES).getValue().toString(), classLoader);
        ClassPathXmlApplicationContext appCtx = new
        ClassPathXmlApplicationContext(springContextFiles, false);
        ApplicationContextHolder contextHolder = new ApplicationContextHolder();
        contextHolder.setApplicationContext(appCtx);
        appCtx.setClassLoader(classLoader);
        appCtx.refresh();
       
        Thread.currentThread().setContextClassLoader(contextCl);
        if (logger.isDebugEnabled()) {
            logger.debug("\n\nstartUp() set spring classloader via axisService.getClassLoader() ... ");
        }
    }

Subject: Axis2 Spring Integration, Problems using

Below I have a snippet from my spring context file that I use in one of my .aar files.

The application works fine when I don't use the ProxyFactoryBean, but when I include it, I get a NoClassDefFoundException for the foo.dao.PayCaptureContextDAO

I did some digging into the spring code and it looks like spring uses the Context class loader to load these classes (and not the AAR deployment classloader, which is where my jar file resides).  Has anyone else encountered this problem?  If so, what was your solution?

I really need to make this work because my web service uses hibernate for persistence and that code uses proxy's for declarative transactions.


    <bean id="methodInvocationTimer" class="foo.MethodInvocationTimer"/>

    <bean id="payCaptureContextDAOTarget" class="foo.PayCaptureContextDAOImpl">
        <property name="sessionFactory">
            <ref local="bmlXASessionFactory"/>
        </property>
    </bean>

    <bean id="payCaptureContextDAO" class="org.springframework.aop.framework.ProxyFactoryBean">
        <property name="proxyInterfaces">
            <value>foo.dao.PayCaptureContextDAO</value>
        </property>
        <property name="interceptorNames">
            <list>
                <value>methodInvocationTimer</value>
            </list>
        </property>
        <property name="target">
            <ref bean="payCaptureContextDAOTarget"/>
        </property>
    </bean>  

Thanks,
