Hi,
we use Axis2 1.4 (JDK 1.4) with Spring 2.0.8 on Weblogic 8.1. As described in
http://ws.apache.org/axis2/1_4/spring.html the "ServiceLifeCycle" was
configured like this:
ClassLoader classLoader = service.getClassLoader();
ClassPathXmlApplicationContext appCtx = new
ClassPathXmlApplicationContext(new String[] {
"my-application-context.xml"}, false);
appCtx.setClassLoader(classLoader);
appCtx.refresh();
In "my-application-context.xml" we add a Spring-Bean to access the ejb:
<bean id="someService"
class="org.springframework.jndi.JndiObjectFactoryBean" lazy-init="true">
<property name="proxyInterface" value="org.SomeService" />
<property name="lookupOnStartup" value="false" />
<property name="jndiName" value="SomeService"/>
<property name="jndiTemplate">
<bean class="org.springframework.jndi.JndiTemplate">
<property name="environment">
<props>
<prop
key="java.naming.factory.initial">weblogic.jndi.WLInitialContextFactory</prop>
<prop
key="java.naming.provider.url">t3://localhost:7001</prop>
<prop
key="java.naming.security.principal">username</prop>
<prop
key="java.naming.security.credentials">password</prop>
</props>
</property>
</bean>
</property>
</bean>
By starting weblogic we get this exception:
... bean with name 'someService' defined in class path resource
[my-application-context.xml]: Invocation of init method failed; nested
exception is java.lang.IllegalArgumentException: interface org.SomeService is
not visible from class loader

By moving the Jar with the EJB-Interface "org.SomeService" into
"axis2.war/WEB-INF/lib", OR changing
the "ServiceLifeCycle" to the following the error above is gone and it seems
that all spring-beans are configured correctly:
ClassLoader contextCl = Thread.currentThread().getContextClassLoader();
ClassLoader classLoader = service.getClassLoader();
Thread.currentThread().setContextClassLoader(classLoader);
ClassPathXmlApplicationContext appCtx =
new ClassPathXmlApplicationContext(
new String[]{"my-application-context.xml"}, false);
appCtx.setClassLoader(classLoader);
appCtx.refresh();
Thread.currentThread().setContextClassLoader(contextCl);
But by calling the EJB from wihthin the Web-Service we get an
IllegaleArgumentException with "type mismatch":
org.springframework.remoting.RemoteProxyFailureException: Invocation of RMI
stub method failed: public abstract org.SomeOutputObject
org.SomeService.someEjbMethode(org.SomeInputObject); nested exception is
java.lang.IllegalArgumentException: argument type mismatch

Is this a generel class loader problem? Is there a workaround?
Thanks for reply!
