I'm trying to access some objects running in Tomcat in a Swing client. I've setup a web application which uses these objects fine, so I know they work. However, I keep encountering ProtocolExceptions with both Hessian and Burlap. I'm sure I'm doing something incorrect; but am having a hard time figuring it out.

Swing Client: In the client, I'm using an XMLBeanFactory to obtain instances to the bean:

Code:
InputStream is = new FileInputStream(
    "C:\\Apps\\eclipse\\workspace\\table_maint\\beans.xml");
XmlBeanFactory factory = new XmlBeanFactory(is);
manager = (CntlMessageBI) factory.getBean("cntlmsg");
According to the log file, the bean is created and returned without any problems. However, when I try to invoke a method, I get the following Hessian error (I get the equivalent error with Burplap):

Code:
org.springframework.remoting.RemoteAccessException: Cannot access Hessian service at [http://localhost:8080/tablemaint/ws/Clinic-hessian]; nested exception is com.caucho.hessian.io.HessianProtocolException: 
com.caucho.hessian.io.HessianProtocolException: 
	at com.caucho.hessian.client.HessianProxy.invoke(HessianProxy.java:171)

	at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:152)
	at $Proxy1.getAllMessages(Unknown Source)
The relevant portions of my configuration files are as follows:

beans.xml - Used by Swing client:

Code:
<beans>
	
	<bean id="cntlmsg" class="org.springframework.remoting.caucho.HessianProxyFactoryBean">
		<property name="serviceInterface">
			<value>tablemaint.datalogic.CntlMessageBI</value>
		</property>
		<property name="serviceUrl">
			<value>http&#58;//localhost&#58;8080/tablemaint/ws/Clinic-hessian</value>
		</property>
	</bean>
	
</beans>
web.xml

Code:
  	<servlet>
		<servlet-name>ws</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<load-on-startup>2</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>ws</servlet-name>
		<url-pattern>/ws/*</url-pattern>
	</servlet-mapping>
ws-servlet.xml - I've only included the portion which creates the Hessian (or Burlap) service. There are about a dozen beans defined in the XML file, but they are all created with no problems according ot the log files

Code:
	    <bean id="cntlMsgMan" class="tablemaint.datalogic.CntlMessageMgr">
        <property name="cntlMessageDao">
            <ref bean="msgManDao"/>
        </property>
    </bean>    

        <bean name="/Clinic-hessian" class="org.springframework.remoting.caucho.HessianServiceExporter">
		<property name="service"><ref bean="cntlMsgMan"/></property>
		<property name="serviceInterface">
			<value>tablemaint.datalogic.CntlMessageBI</value>
		</property>
	</bean>
I borrowed this code from the sample projects assuming I could get it up and running quickly. I've been able to defeat that assumption.

Thanks in advance for any insight,
