HttpInvoker and SLSB

[afida]

This might have been answered somewhere but i just can't seem to find the solution.

I simply wnt to expose my SLSB through HttpInvoker so my rich client can access it. My app is packaged in ear.

ws.servlet

  <!-- HttpInvoker exporter for the core service -->
  <bean name="/rbacx-httpInvoker" class="org.springframework.remoting.httpinvoker.HttpInvokerServiceExporter">
    <property name="service"><ref bean="core"/></property>
    <property name="serviceInterface"><value>com.vaau.core.MainService</value></property>
  </bean>

what i want to is have something like this

<bean id="core" lazy-init="true" class="org.springframework.ejb.access.LocalStatelessSessionProxyFactoryBean">
        <property name="jndiName">
	    <value>local/coreSLSB</value>
	</property>
	<property name="businessInterface">
	    <value>com.vaau.core.MainService</value>
	</property>
    </bean>

I just not sure where to define this bean "core". I have tried declaring this into my aplicationContext.xml but when i executure my business method I get,

org.springframework.beans.FatalBeanException: Unable to return specified BeanFactory instance: factory key [java:comp/env/ejb/BeanFactoryPat

Please help me !!! I am going Nuts over this...

The problem appears to be caused by the fact the your SLSB extends AbstractStatelessSessionBean. You should only extends this class if you need to access a Spring application context in your SLBS. If you don't need that try overwriting the setSessionContext and ejbCreate methods like this:

   public void setSessionContext(SessionContext sessionContext) {
       super.setSessionContext(sessionContext);
       setBeanFactoryLocator(null);
   }

   public void ejbCreate() {
       onEjbCreate();
   }

If you do this make sure you don't call the getBeanFactory or you will get a NullPointerException. You may also consider to not extend AbstractStatelessSessionBean at all.

THanks, But i think i need to accesss the spring context as i have my business interface implmentation bean defined in context. Because slsb uses this delegate to get implementation.

I refer to another post I wrote today:

If you're interested let me know.

[afida]

If thats the only way to have a shared context between web app and ejb then yes i am very much interested.

Thanks

I'll get back to you when it's finished.
