how to configure an embed broker with an optional tcp transport

[christophe blin <cb...@tennaxia.com>]

Hi,

I'd like to configure an embed broker that use vm and tcp transport, but
with the tcp tranport being optional.
At the moment, if I use a blank value for the tcp transport, then the bean
initialisation failed (see at the bottom of this message).

If this is not very clear, here is an example of what I'd like to do.

The following is working :

  <bean id="broker" class="org.apache.activemq.xbean.XBeanBrokerService">
    <property name="persistenceAdapter">
      <bean class="org.apache.activemq.store.jdbc.JDBCPersistenceAdapter">
        <property name="dataSource" ref="ds" />
      </bean>
    </property>
    <property name="transportConnectorURIs">
      <list>
        <value>vm://localhost</value>
        <value>tcp://localhost:61365</value><!-- and sometimes
<value></value> -->
      </list>
    </property>
    <property name="start" value="true" />
  </bean>

What I'd like is to externalize the "tcp://localhost:61365" into a
properties file and to make it optional (i.e if the user said
"jms.embedbroker=" then I do not want the exception to appear)

exception that appear if I use a blank value :
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'broker' defined in class path resource [jms-spring.xml]:
Invocation of init method failed; nested exception is java.io.IOException:
Transport not scheme specified: []

thanks for any help,
regards,
chris

I'd suggest using your own Java code to construct the broker, then you
can use an if () around the
broker.addConnector("tcp://localhost:port")) line of code.

Some example code here...
http://incubator.apache.org/activemq/how-do-i-embed-a-broker-inside-a-connection.html

If you really want you could wrap up your Java code as a Spring FactoryBean
