> -----------------------------------------------------------
>
> Key: AXIS2-3230
> URL: https://issues.apache.org/jira/browse/AXIS2-3230
> Project: Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: deployment
> Affects Versions: 1.3
> Environment: tomcat 5.5.25
> jre 1.5.0.12
> windows xp
> Reporter: ed p
> Priority: Critical
>
> I have a simple webservice proxied by a Spring proxy factory bean.
> The spring context is configured as so:
> <bean id="simpleWebService" class="org.springframework.aop.framework.ProxyFactoryBean">
> <property name="proxyInterfaces"><value>com.test.simpleWebService</value></property>
> <property name="target"><ref local="simpleWebServiceTarget"/></property>
> <property name="interceptorNames">
> <list>
> <value>methodAuditInterceptor</value>
> </list>
> </property>
> </bean>
> <bean id="simpleWebServiceTarget" class="com.test.simpleWebServiceImpl">
> The services.xml is:
> <service name="SimpleWebService">
> <parameter name="ServiceObjectSupplier">
> org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier
> </parameter>
> <parameter name="SpringBeanName">simpleWebService</parameter>
> <messageReceivers>
> <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
> class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
> <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
> class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
> </messageReceivers>
> </service>
> At runtime, Spring generates a JDK proxy around the simple web service. When the axis2 service deployer tries to deploy this webservice it generates the following stacktrace:

> From the stacktrace it appears that java2wsdl requires the bytecode but because the proxy is generated in memory it doesn't exist.
> I have though about a couple of workarounds including:
> 1) Using AspectJ to weave at compile time (starting to make the application more complex and I am not sure if this will work)
> 2) Provide a pregenerated WSDL (I can create the WSDL myself) so that I can bypass this step during deployment? Is this possible?
