ClassNotFoundException WSServlet with Tomcat 7.0.11 on Windows Server 2008 R2 using METRO 2.1

[Howard Smalley]

Hi
 
I'm trying to create a simple webservice using Tomcat 7.0.11 on Windows Server 
2008 R2 (64bit) using Metro 2.1. I'm coming from a C#/WCF background trying to 
get a better understanding on web service interopability. I'm actually 
following an example from Martin Kalin's book "Java Web Services Up and 
Running". I have the following:
 
CATALINA_HOME=c:\tomcat-7.0.11
 
in the catalina.properties file I have:
server.loader=c:/metro-2.1/bin/*.jar 
 
(note, I also tried adding this path to common.loader too).
 
I've copied to the following METRO jar files to CALALINA_HOME\lib:
webservices-api.jar, webservices-extra.jar, webservices-extra-api.jar, 
webservices-rt.jar, webservices-tools.jar
 
and to CATALINA_HOME\endorsed:
webservices-api.jar
 
(note, I originally tried using the metro-on-tomcat.xml ant file but it doesn't 
seem to have been updated for tomcat 7.*)
 
I've also copied webservices-api.jar to JAVA_HOME\jre\lib\endorsed
 
I've tried putting the other METRO jars in the above locations aswell too but 
to no help.
 
Now, Tomcat starts up ok and initializes METRO ok, here's the relevant section 
from the catalina log file:
INFO: Deploying web application directory ROOT
18-May-2011 08:00:55 
com.sun.xml.ws.transport.http.servlet.WSServletContextListener 
contextInitialized
INFO: WSSERVLET12: JAX-WS context listener initializing
18-May-2011 08:01:07 com.sun.xml.ws.server.MonitorBase createRoot
INFO: Metro monitoring rootname successfully set to: 
com.sun.metro:pp=/,type=WSEndpoint,name=-TempConvertImplService-TempConvertImplPort
18-May-2011 08:01:08 com.sun.xml.ws.transport.http.servlet.WSServletDelegate 
<init>
INFO: WSSERVLET14: JAX-WS servlet initializing
 
So from that you'd think that Tomcat had loaded all the METRO classes. From 
what I have gathered WSServlet is part of JAX-WS 2.1 which is shipped as part 
of METRO so it should have been loaded. But when I actually try to browse to 
the WSDL of my service I get the following in the localhost log:
SEVERE: Allocate exception for servlet TempConvertWS
java.lang.ClassNotFoundException: com.sun.xml.ws.transport.http.WSServlet
 at 
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1676)
 at 
org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1521)
 at 
org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:415)....
 (rest of stack trace)
 
my sun-jaxws.xml looks like this:
<endpoints xmlns="http://java.sun.com/xml/ns/jax-ws/ri/runtime"; version="2.0">
  <endpoint
      name="TempConvertWS"
      implementation="TimeServer.TempConvertImpl"
      url-pattern="/tc"
    />
</endpoints>
 
and the relevant section from my web.xml file is:
  <listener>
    
<listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class>
  </listener>
  <servlet>
    <servlet-name>TempConvertWS</servlet-name>
    <servlet-class>com.sun.xml.ws.transport.http.WSServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>TempConvertWS</servlet-name>
    <url-pattern>/tc</url-pattern>
  </servlet-mapping>
 
Can anyone see from that why Tomcat can't find/load the WSServlet class when 
browsing to the service? 
Is this actually a Tomcat configuration error or a problem with METRO?
 
Any help greatly appreciated!
 
Thanks
