Method Detail

setJavaCommand

public void setJavaCommand(JavaCommand cmd)

Only called when no JavaCommand was passed via constructor

getJavaCommand

public JavaCommand getJavaCommand()

executeAsync

public void executeAsync()
                  throws java.lang.Exception

Description copied from class: AbstractAsyncTask

Must be overridden to perform the async part. From within this method you may directly call AbstractAsyncTask.notifyProceeded(Object, int, int, String) in order to notify about task progress. Note: the running task should periodically call AbstractAsyncExecutable.checkCancelled() in order to detect cancellation.

Specified by:

executeAsync in interface AsyncExecutable<C extends ApplicationContext>

Overrides:

executeAsync in class AbstractOsProcessTask<C extends ApplicationContext>

Throws:

java.lang.Exception
