The server code cannot find MethodCounter.class.

I do not know how you installed Apache SOAP, but here is the "standard" description.  Apache SOAP should be installed as a webapp within the servlet container, in your case Tomcat.  I personally prefer un-jarring the soap.war in $CATALINA_HOME/webapps/soap, rather than dropping soap.war in $CATALINA_HOME/webapps.  The service classes can then be dropped under $CATALINA_HOME/webapps/soap/WEB-INF/classes.

In your case, you would have the file $CATALINA_HOME/webapps/soap/WEB-INF/classes/javasoap/book/ch4/MethodCount.class

Do not send e-mail directly to this e-mail address,
because it is filtered to accept only mail from
specific mail lists.
