Method Details

init

public static void init()

Initializes all App engines that can be found on the classpath for resources flowable.app.cfg.xml and for resources flowable-app-context.xml (Spring style configuration).

getAppEngineInfos

public static List<EngineInfo> getAppEngineInfos()

Get initialization results.

getAppEngineInfo

public static EngineInfo getAppEngineInfo(String appEngineName)

Get initialization results. Only info will we available for app engines which were added in the init(). No EngineInfo is available for engines which were registered programmatically.

getDefaultAppEngine

public static AppEngine getDefaultAppEngine()

getAppEngine

Obtain an app engine by name.

Parameters:

appEngineName - is the name of the app engine or null for the default app engine.

retry
