Hi,
I tried to deploy a small phonebook example which uses an entity bean
phonebook.EntryBean for the entries and a stateless session bean
phonebook.PhonebookBean with remote interfaces to manage these entries. I am
using DTOs implementing java.io.Serializable with zero-arg constructors to
transfer the data between client and session bean. Now I tried to expose the
session bean also as a web service. Therefore, I created the following service
endpoint interface which signatures is similar to the method signatures in the
session bean:
package phonebook;
|
| import java.rmi.Remote;
| import java.rmi.RemoteException;
|
| public interface PhonebookSEI extends Remote {
|
| public EntryDTO findEntry(String firstname, String lastname) throws
RemoteException;
| public void createNewEntry(EntryDTO entry) throws RemoteException;
| public EntryDTO[] getEntries() throws RemoteException;
|
| }
Then, I wrote a config.xml for the wscompile tool loooking like this:
<?xml version="1.0" encoding="UTF-8"?>
| <configuration xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config";>
| <service name="PhonebookService"
| targetNamespace="http://phonebook";
| typeNamespace="http://phonebook/types";
| packageName="phonebook">
| <interface name="phonebook.PhonebookSEI"
| servantName="phonebook.PhonebookBean" />
| </service>
| </configuration>
and used wscompile to create the following WSDL file
<?xml version="1.0" encoding="UTF-8"?>
|
| <definitions name="PhonebookService" targetNamespace="http://phonebook";
xmlns:tns="http://phonebook"; xmlns="http://schemas.xmlsoap.org/wsdl/";

In ejb-jar.xml, I added the service endpoint like this:
<session>
| <ejb-name>Phonebook</ejb-name>
| <service-endpoint>phonebook.PhonebookSEI</service-endpoint>
| <home>phonebook.PhonebookHome</home>
| ...
| </session>
|
and write the webservices.xml like that:
<webservices xmlns="http://java.sun.com/xml/ns/j2ee";
| xmlns:impl="http://phonebook/ws4ee";
| xmlns:xsi="http://www.w3.org/2001/XMLSchema.instance";
| xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://www.ibm.com/webservices/xsd/j2ee_web_services_1_1.xsd";
| version="1.1">
| <webservice-description>
|
<webservice-description-name>PhonebookService</webservice-description-name>
| <wsdl-file>META-INF/wsdl/PhonebookService.wsdl</wsdl-file>
|
<jaxrpc-mapping-file>META-INF/PhonebookService_mapping.xml</jaxrpc-mapping-file>
| <port-component>
| <port-component-name>PhonebookSEI</port-component-name>
| <wsdl-port>PhonebookSEIPort</wsdl-port>
|
<service-endpoint-interface>phonebook.PhonebookSEI</service-endpoint-interface>
| <service-impl-bean>
| <ejb-link>ejb/PhonebookBean</ejb-link>
| </service-impl-bean>
| </port-component>
| </webservice-description>
| </webservices>
When I now jar the beans and deploy them on JBoss 4.0.3 SP 1, I get the
following exception:

I have double-checked everything to my best knowledge, however, I don't find
the error. Is this a bug, or have I missed something?
