NPE while deploying SLSB as Web Service on JBoss 4.0.3SP1
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/" xmlns:ns2="http://phonebook/types" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"> <types> <schema targetNamespace="http://phonebook/types" xmlns:tns="http://phonebook/types" xmlns:soap11-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns="http://www.w3.org/2001/XMLSchema"> <complexType name="createNewEntry"> <sequence> <element name="EntryDTO_1" type="tns:EntryDTO" nillable="true"/></sequence></complexType> <complexType name="EntryDTO"> <sequence> <element name="dateOfBirth" type="dateTime" nillable="true"/> <element name="firstname" type="string" nillable="true"/> <element name="lastname" type="string" nillable="true"/> <element name="telephoneNumber" type="string" nillable="true"/></sequence></complexType> <complexType name="createNewEntryResponse"> <sequence/></complexType> <complexType name="findEntry"> <sequence> <element name="String_1" type="string" nillable="true"/> <element name="String_2" type="string" nillable="true"/></sequence></complexType> <complexType name="findEntryResponse"> <sequence> <element name="result" type="tns:EntryDTO" nillable="true"/></sequence></complexType> <complexType name="getEntries"> <sequence/></complexType> <complexType name="getEntriesResponse"> <sequence> <element name="result" type="tns:EntryDTO" nillable="true" minOccurs="0" maxOccurs="unbounded"/></sequence></complexType> <element name="createNewEntry" type="tns:createNewEntry"/> <element name="createNewEntryResponse" type="tns:createNewEntryResponse"/> <element name="findEntry" type="tns:findEntry"/> <element name="findEntryResponse" type="tns:findEntryResponse"/> <element name="getEntries" type="tns:getEntries"/> <element name="getEntriesResponse" type="tns:getEntriesResponse"/></schema></types> <message name="PhonebookSEI_createNewEntry"> <part name="parameters" element="ns2:createNewEntry"/></message> <message name="PhonebookSEI_createNewEntryResponse"> <part name="result" element="ns2:createNewEntryResponse"/></message> <message name="PhonebookSEI_findEntry"> <part name="parameters" element="ns2:findEntry"/></message> <message name="PhonebookSEI_findEntryResponse"> <part name="result" element="ns2:findEntryResponse"/></message> <message name="PhonebookSEI_getEntries"> <part name="parameters" element="ns2:getEntries"/></message> <message name="PhonebookSEI_getEntriesResponse"> <part name="result" element="ns2:getEntriesResponse"/></message> <portType name="PhonebookSEI"> <operation name="createNewEntry"> <input message="tns:PhonebookSEI_createNewEntry"/> <output message="tns:PhonebookSEI_createNewEntryResponse"/></operation> <operation name="findEntry"> <input message="tns:PhonebookSEI_findEntry"/> <output message="tns:PhonebookSEI_findEntryResponse"/></operation> <operation name="getEntries"> <input message="tns:PhonebookSEI_getEntries"/> <output message="tns:PhonebookSEI_getEntriesResponse"/></operation></portType> <binding name="PhonebookSEIBinding" type="tns:PhonebookSEI"> <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/> <operation name="createNewEntry"> <soap:operation soapAction=""/> <input> <soap:body use="literal"/></input> <output> <soap:body use="literal"/></output></operation> <operation name="findEntry"> <soap:operation soapAction=""/> <input> <soap:body use="literal"/></input> <output> <soap:body use="literal"/></output></operation> <operation name="getEntries"> <soap:operation soapAction=""/> <input> <soap:body use="literal"/></input> <output> <soap:body use="literal"/></output></operation></binding> <service name="PhonebookService"> <port name="PhonebookSEIPort" binding="tns:PhonebookSEIBinding"> <soap:address location="REPLACE_WITH_ACTUAL_URL"/></port></service></definitions>
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?
