Class LaunchJob

java.lang.Object
  org.oddjob.jobs.LaunchJob

All Implemented Interfaces:

Serializable, Runnable

public class LaunchJob
extends Object
implements Runnable, Serializable

Description

Launch an application via it's main method. The application is launched in same JVM as Oddjob, but in it's own class loader.

Example

An Oddjob the launches Oddjob. args[0] is org.oddjob.Main, args[1] is the oddjob home directory. The classes directory is included in the class path for the log4j.properties file otherwise Log4j would attempt to use one from ClassLoader.getSystemLoader() which will be the original application class loader.

<oddjob id="this">
    <job>
        <launch className="${this.args[1]}">
            <args>
                <list>
                    <values>
                        <value value="-nb"/>
                        <value value="-f"/>
                        <value value="${this.args[0]}/test/conf/echo-class-loader.xml"/>
                    </values>
                </list>
            </args>
            <classLoader>
                <url-class-loader noInherit="true">
                    <files>
                        <files files="${this.args[0]}/lib/*.jar">
                            <list>
                                <file file="${this.args[0]}/opt/classes"/>
                            </list>
                        </files>
                    </files>
                </url-class-loader>
            </classLoader>
        </launch>
    </job>
</oddjob>
