classForName

public static Class classForName(String className)
                          throws ClassNotFoundException

Throws:

ClassNotFoundException

classForName

public static Class classForName(String className,
                                 boolean useConfiguredLoader)
                          throws ClassNotFoundException

Throws:

ClassNotFoundException

getClassLoader

public static 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 InputStream getStream(String resource)

getStream

public static InputStream getStream(String resource,
                                    boolean useConfiguredLoader)

Returns a stream for reading the specified resource. This method helps bootstrap jBPM because the class loader used for locating the configuration resource cannot be configured in the configuration itself.

Parameters:

useConfiguredLoader - if true, this method searches for the resource in the context class loader, if not found it falls back on the loader of this class

Returns:

a stream for reading the resource, or null if the resource was not found

getProperties

public static Properties getProperties(String resource)
