How to create my own gateway classes

[andreasriedel]

Hello.

Take a look in the jbossesb-1.2.0.xsd, there exists a amount of predefined Providers:

- jms-provider-type
- jms-jca-provider
- fs-provider
- ftp-provider
- sql-provider
- hibernate-provider
- jbr-provider
- http-provider

By defining the listener in the jboss-esb.xml no class is given, so I guess there can only be reference a fix set of Gateway Classes:

  SqlTableGatewayListener.java
  FileGatewayListener.java
  HibernateGatewayListener.java
  HttpGatewayListener.java
  JBossRemotingGatewayListener.java
  JmsGatewayListener.java

So the question is:

- is it possible to define my own provider.

- how can I create my own Gateway Class or extend an existing.

- is there an guide or tutorial explain what's to do.

TIA

You can do your own implementation of org.jboss.soa.esb.listeners.ScheduledEventMessageComposer.

Then you should define the Schedule Provider and then the instance of Scheduled Listener containing the definition of your class as EventProcessor.

It's not that hard to do the implementation.

I'm more interesset in how to use it. It's to define and I'm looking for some documention how to do so.

The simple example might be as follows:

In jboss-esb.xml in section <providers> define:

  <schedule-provider name="MySchedProvider">

   <simple-schedule frequency="30" frequencyUnits="seconds" scheduleid="MySimpleSchedule"/>

  </schedule-provider>

Then in section <services><service><listeners> define:

<scheduled-listener

     event-processor="MyMessageComposerImplementationClass"

     is-gateway="true" name="MyScheduledListener" scheduleidref="MySimpleSchedule">

     <property name="param" value="value"/>

    </scheduled-listener>

properties <param,value> have the same meaning as ConfigTree for Action classes.

In the above example the method composeMessage() of MyMessageComposerImplementationClass is invoked in every 30 seconds.
