Hi, I have the same problem with jboss 4.0.4.GA and EJB3. When I redeploy my ejb, I get: javax.ejb.EJBException: java.lang.IllegalArgumentException: Wrong target... when invoking any method with instances of my own classes as parameters. A restart of the server fixes the problem. I have an EJB3 with an EJB2.1 compatible remote homeinterface (using the @RemoteHome(MyBeanHome.class) annotation). I have tried several ways to access the ejb: Through an AXIS 1.4 webservice as front, a small javaclient and using JBossWS as front. The strange thing is that all attempts fail except invoking it through the JBossWS webservice. Even after a redeploy, when all fail using the javaclient and through axis, I can still invoke all methods through JBossWS. After I restart the server, everything works perfectly. My Bean: | @WebService( | name="TestService", | serviceName="TestServiceService", | targetNamespace="http://test.myhome.org/testservice") | @SOAPBinding( | style=Style.DOCUMENT, | use=Use.LITERAL, | parameterStyle=ParameterStyle.WRAPPED) | @Stateless(name="TestService") | @Remote | @RemoteHome(TestServiceHome.class) | @RemoteBinding(jndiBinding = "ejb/TestService") | public class TestServiceSessionBean implements TestService { | | @WebMethod | public MyResponse myMethod(MyParameters params) { | | } | } | I have tried different versions of EJB3 with no luck (RC7 & RC9).
