Class EclipseDaemon

java.lang.Object

org.eclipse.scada.utils.osgi.daemon.EclipseDaemon

public class EclipseDaemon
extends Object

This is a simple wrapper class for the EclipseStarter
The problem is that the "prunsrv.exe" of Apache Commons Daemon expects the stop method to also accept arguments of type String[].

public static void main(String[] args)
                 throws Exception

Exception - if anything goes wrong

start

public static void start(String[] args)
                  throws Exception

The method will actually fork a thread and run the started method from inside the thread. If the framework fails the method checks isExitOnError() on how to proceed. If isExitOnError() returns true then the method will call System.exit(int) with a negative return value (-1). Otherwise only the thread starting the framework will shut down.

Parameters:

args - arguments for the starter

Throws:

Exception - if anything goes wrong

isExitOnError

protected static boolean isExitOnError()

Otherwise the evaluate the value of the system property using Boolean.parseBoolean(String).

Returns:
