[jboss-user] [EJB 3.0] - Re: Problem calling SLSBs from isolated EARs

The behaviour for CallByValue is described in http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration as: Call By Value 1. caller does ejb.someMethod() 2. invocation is marshalled - the parameters are turned into ObjectStream? (a byte[]) 3. container with a different classloader unmarshalls - byte[] -> java Objects - including classloading 4. invocation is passed through ejb container 5. container does bean.someMethod() 6. result is marshalled - the return value is turned into ObjectStream? 7. result is unmarshalled using the caller's classloader - byte[] -> java Object 8. result is return to the caller If a call "proxy.f(myType)" is done via Call By Value in step 2. the parameter myType should be serialized. I modified MyType to debug de-/serialization: public class MyType implements Serializable { | public String str; | private void writeObject(ObjectOutputStream out) throws IOException | { | // debug | out.defaultWriteObject(); | } | | private void readObject(ObjectInputStream in) throws IOException, ClassNotFoundException | { | in.defaultReadObject(); | // debug | } | } If a call via remote interface is made from a client-java-app the writeObject() and readObject() methods get called. If a call is made from inside a SLSB (local interface) neither method gets called. So the step 2. (marshall parameters) is missing. Did I miss something in the configurations? conf/jboss-service.xml: ... | <mbean code="org.jboss.naming.NamingService" name="jboss:service=Naming" xmbean-dd="resource:xmdesc/NamingService-xmbean.xml"> | <attribute name="CallByValue">true</attribute> | <attribute name="Port">1099</attribute> | <attribute name="BindAddress">${jboss.bind.address}</attribute> | <attribute name="RmiPort">1098</attribute> | <attribute name="RmiBindAddress">${jboss.bind.address}</attribute> | <depends optional-attribute-name="LookupPool" proxy-type="attribute">jboss.system:service=ThreadPool</depends> | </mbean> | ... deploy/ear-deployer.xml: <server> | <mbean code="org.jboss.deployment.EARDeployer" name="jboss.j2ee:service=EARDeployer"> | <attribute name="Isolated">true</attribute> | <attribute name="CallByValue">true</attribute> | </mbean> | </server> EAR1: META-INF/jboss-app.xml: <jboss-app> | <loader-repository>mydomain:loader=mycomponent1</loader-repository> | </jboss-app> EAR2: META-INF/jboss-app.xml: <jboss-app> | <loader-repository>mydomain:loader=mycomponent2</loader-repository> | </jboss-app> View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3969648#...
