10.3. 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
<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>
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
