Class Boot
java.lang.Objectorg.jboss.tools.Boot
- public class Boot
- extends Object
Starts multiple applications using seperate classloaders.
This allows multiple applications to co-exist even if they typicaly could not due to
class version problems. Each application is started in it's own thread.
Usage is Boot [-debug] -cp app-classpath app-class-name app-arguments ( , -cp app-classpath app-class-name app-arguments )*
Where:
app-classpath is a comma seperated URL form classpath to the application classes.
app-class-name is the class that will be started
app-arguments will be the String[] that will be passed to the main method of the application class
Jboss + Another Application boot example:
Boot -cp file:run.jar org.jboss.Main default , -cp file:./myapp.jar,file:./util.jar test.App2TEST arg1 arg2
Would start the JBoss Server using the default configuration and it would
start the test.App2TEST application.
Important Note: Notice that there are spaces before and after the ","!!!
You can now boot other applications via ths Boot class from withing one of the applications
that was booted by the Boot.
Example usage:
Boot b = Boot.getInstance();
Boot.ApplicationBoot ab = b.createApplicationBoot();
ab.applicationClass = "org.jboss.Main"
ab.classpath.add(new URL("file:run.jar"));
ab.args.add("default");
// this would start the application in a new thread.
b.startApplication( ab );
// Would boot the appp in the current thread.
ab.boot();
