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)
                                    throws java.lang.ClassNotFoundException

Throws:

java.lang.ClassNotFoundException

classForName

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

Throws:

java.lang.ClassNotFoundException

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)

Loads resource as stream. If useConfiguredLoader is true, this method searches for the resource in the context class loader, if not found it searches in the class loader of this class.

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

Returns:

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

getProperties

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