      Hi,
      I'm trying to get a SimpleWebservice to work. I'm still a newbie at this, so pleace forgive me for asking stupid questions.

      I've started from a SessionBean (a simple calculator) and I get the following error when deploying:

      03:44:57,984 ERROR [ServiceDeployer] Cannot startup webservice for: SimpleEJBs.jar

      My ejb-jar.xml file looks like this: 
      <?xml version="1.0" encoding="UTF-8"?>

<ejb-jar version="2.1" xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
 http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd">>
 <enterprise-beans>
 <session>
 <display-name>Calculator</display-name>
 <ejb-name>CalculatorEJB</ejb-name>
 <ejb-class>simple.test.CalculatorBean</ejb-class>
 <service-endpoint>simple.test.Calculator</service-endpoint>
 <session-type>Stateless</session-type>
 <transaction-type>Container</transaction-type>
 </session>
 </enterprise-beans>
</ejb-jar>



      This is my webservices.xml file: 

      <webservices xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
 http://www-124.ibm.com/developerworks/opensource/jsr109/xsd/j2ee_web_services_1_1.xsd" version="1.1">
 <webservice-description>
 <webservice-description-name>CalculatorService</webservice-description-name>
 <wsdl-file>META-INF/wsdl/calculator.wsdl</wsdl-file>
 <jaxrpc-mapping-file>META-INF/mapping.xml</jaxrpc-mapping-file>
 <port-component>
 <port-component-name>Calculator</port-component-name>
 <wsdl-port>Calculator</wsdl-port>
 <service-endpoint-interface>simple.test.Calculator</service-endpoint-interface>
 <service-impl-bean>
 <ejb-link>CalculatorBean</ejb-link>
 </service-impl-bean>
 </port-component>
 </webservice-description>
 </webservices>



      Mapping.xml is as follows: 
      <java-wsdl-mapping xmlns="http://java.sun.com/xml/ns/j2ee"
 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_jaxrpc_mapping_1_1.xsd"
 version="1.1">
 <package-mapping>
 <package-type>simple.test</package-type>
 <namespaceURI>urn:simple.test.CalculatorService</namespaceURI>
 </package-mapping>
</java-wsdl-mapping>






      Can somebody see why this error occors upon deployment?

      I wish there was a website that explains all the deployment descriptors step by step, cause most tutorials just list out these xml-files without explaining them. Any links you would like share? ;-)

      THANKS ALOT !!!
      I really hope, i'll get it right someday
