public class InvokeJob
extends SerializableJob
implements Stoppable

Description

Invoke a java method or script snippet.

This is a wrapper for InvokeType. The result of the invocation is placed in the result property.

Note that stopping this job will simply attempt to interrupt the thread invoking the method. The outcome of this will obviously vary.

Oddjob will do it's best to convert arguments to the signature of the method or operation. An exception will result if it can't achieve this.

Example

Invoking a method on a bean.

<oddjob>
    <job>
        <sequential>
            <jobs>
                <invoke id="invoke-job" function="echo">
                    <source>
                        <bean class="org.oddjob.script.EchoService"/>
                    </source>
                    <parameters>
                        <value value="Hello"/>
                    </parameters>
                </invoke>
                <echo id="echo">${invoke-job.result}</echo>
            </jobs>
        </sequential>
    </job>
</oddjob>

Where EchoService is: org/oddjob/script/EchoService.java

Example

Invoking a static method. Note that this uses args instead of parameters for convenience.

<oddjob>
    <job>
        <invoke function="static totalPrice" id="invoke-totalPrice">
            <args>
                <tokenizer text="Red Apples, 24, 47.3"/>
            </args>
            <source>
                <class name="org.oddjob.script.InvokeJobTest"/>
            </source>
        </invoke>
    </job>
</oddjob>

Example

Examples elsewhere.

See InvokeType for several more examples. Property configuration is the same for the type and the job.

The JMXServiceJob job has an example of invoking a JMX operation.
