  oracle.jbo.common.PropertyManager

public class PropertyManager

extends java.lang.Object

Internal: Applications should not use this class.

This class is used at framework initialization time to choose values for the various properties that can be set in the system.

Method Detail

main

public static void main(java.lang.String[] args)

This entrypoint is retained as a user convenience: if invoked it lists all the known BC4J system properties, their default values, and their ownership.

Since:

3.1

setProperty

public static void setProperty(java.lang.Object owner,
                               PropertyMetadata meta,
                               java.lang.Object value)

loadProperties

public static java.util.Hashtable loadProperties(java.util.Hashtable clientenv)

Load a BC4J system properties from all known sources The sources are:

1. Marshalled client environment

2. Applet tags

3. -D flags (appear in System.properties)

4. bc4j.properties file

5. oracle.jbo.BC4J.properties resource

6. oracle.jbo.commom.jboserver.properties resource

7. oracle.jbo.common.Diagnostic.properties resource

8. System defined default returns a Hashtable of values destines for the session environment

loadProperty

public static void loadProperty(PropertyMetadata propdesc,
                                java.util.Hashtable sessionenv,
                                java.util.Hashtable clientenv,
                                java.applet.Applet applet,
                                java.util.Properties systemProperties,
                                java.util.Properties bc4jFile,
                                java.util.Properties bc4jResource,
                                java.util.Properties jboserverResource,
                                java.util.Properties diagnosticResource)

load an invididual property, using the published sources in order, when found, put it into the correct published place. Also, *remove* the property from the transient Hashtables, so that we can report unused properties at the end.

loadFromAppletTags

public static void loadFromAppletTags(java.util.Hashtable env,
                                      java.applet.Applet applet)

Given an applet and an environment, look for any known properties within the applet's param tags, and load them into the environment, replacing existing environment values if necessary. Notice that we expect this routine to be called by Client code *before* the client environment is marshalled.
