Method Detail

loadClass

public static java.lang.Class loadClass(java.lang.String className)

Deprecated. Use classForName(String) instead

classForName

public static java.lang.Class classForName(java.lang.String className)

classForName

public static java.lang.Class classForName(java.lang.String className,
                                           boolean useConfiguredLoader)

getClassLoader

public static java.lang.ClassLoader getClassLoader()

Returns the ClassLoader employed by jBPM to load classes referenced in the configuration. The class loader can be changed in jbpm.cfg.xml by setting the string property jbpm.class.loader. The possible values are:

• jbpm (default) indicates the class loader of the jBPM classes. Before JBPM-1148 no other behavior was available
• context indicates the context class loader
• any other value is interpreted as a reference to a class loader bean described in the configuration

getStream

public static java.io.InputStream getStream(java.lang.String resource)

getStream

public static java.io.InputStream getStream(java.lang.String resource,
                                            boolean useConfiguredLoader)

Load jbpm configuration related resources as stream (normally jbpm.cfg.xml). This method first tries to load the resource from the ClassLoaderUtil class loader, if not found it tries the context class loader. If this doesn't return any ressource the call is delegated to the class loader configured by calling getClassLoader(). This is a special method because the class loader which has to be used for loading the jbpm.cfg.xml cannot be configured in the jbpm.cfg.xml itself.

getProperties

public static java.util.Properties getProperties(java.lang.String resource)
