14.3. Multihomed servers

Remoting can create servers bound to multiple interfaces. One application of this facility would be binding a server to one interface that faces the internet and another that faces a LAN. For example, the preceding POJO example can be modified by (1) adding POJOs 
   <!-- Beans homes1 and homes2 are used to construct a multihome Remoting server. -->
   <bean name="homes1" class="java.lang.StringBuffer">
      <constructor>
         <parameter class="java.lang.String">
            <value-factory bean="ServiceBindingManager" method="getStringBinding">
               <parameter>JBMConnector:bindingHome1</parameter>
               <parameter>${host}:${port}</parameter>
            </value-factory>
         </parameter>
      </constructor>
   </bean>
   
   <bean name="homes2" class="java.lang.StringBuffer">
      <constructor factoryMethod="append">
         <factory bean="homes1"/>
         <parameter>
            <value-factory bean="ServiceBindingManager" method="getStringBinding">
               <parameter>JBMConnector:bindingHome2</parameter>
               <parameter>!${host}:${port}</parameter>
            </value-factory>
         </parameter>
      </constructor>
   </bean>

which results in a StringBuffer with a value something like (according to the ServiceBindingManager configuration values for JBMConnector:bindingHome1 and JBMConnector:bindingHome2) "external.acme.com:5555!internal.acme.com:4444", and (2) replacing the "serverBindAddress" and "serverBindPort" parameters with 
    <entry>
      <key>homes</key>
      <value><value-factory bean="homes2" method="toString"/></value>
    </entry>
Copy to Clipboard Toggle word wrap
which transforms the StringBuffer into the String "external.acme.com:5555!internal.acme.com:4444" and injects it into the JBMConnector. The resulting InvokerLocator will look like 
    bisocket://multihome/?homes=external.acme.com:5555!internal.acme.com:
    4444&marshaller=org.jboss.jms.wireformat.JMSWireFormat&
    unmarshaller=org.jboss.jms.wireformat.JMSWireFormat
