Static Operation Selector

specify a operation name in the configuration.

<hornetq:binding.hornetq>
    <selector:operationSelector operationName="greet"/>
(... snip ...)
</hornetq:binding.hornetq>

XPath Operation Selector

specify a XPath location which contains a operation name to be invoked in the message contents.

If the configuration looks like this:

<jca:binding.jca>
    <selector:operationSelector.xpath expression="//person/language"/>
(... snip ...)
</jca:binding.jca>

And the message content is like this:

<person>
    <name>Fernando</name>
    <language>spanish</language>
</person>

Then operation spanish() would be invoked.

Regex Operation Selector

specify a Regular Expression to find a operation name to be invoked in the message contents.

If the configuration looks like this:

<http:binding.http>
    <selector:operationSelector.regex expression="[a-zA-Z]*Operation"/>
(... snip ...)
</http:binding.http>

And the message content is like this:

xxx yyy zzz regexOperation aaa bbb ccc

Then operation regexOperation() would be invoked.

Java Operation Selector

specify a Java class which is able to determine the operation to be invoked.

configuration should look like this:

<jca:binding.jca>
    <selector:operationSelector.java class="org.switchyard.example.MyOperationSelectorImpl"/>
(... snip ...)
</jca:binding.jca>

Note that the org.switchyard.example.MyOperationSelectorImpl needs to be a subclass of org.switchyard.component.common.selector.OperationSelector or other concrete OperationSelector classes for each service bindings. You can override the selectOperation() method as you like.

Default OperationSelector implementation for each service bindings are following:

• Camel : org.switchyard.component.camel.selector.CamelOperationSelector

• JCA/JMS : org.switchyard.component.jca.selector.JMSOperationSelector

• JCA/CCI : org.switchyard.component.jca.selector.CCIOperationSelector

• HTTP : org.switchyard.component.http.selector.HttpOperationSelector

Scope of Support

Support for operation selector is limited to Camel, JCA and HTTP service bindings. Support for other service bindings will be added in the future.
