|Das im Anhang "Erweitern der Steuerzentrale" aufgeführte Beispiel ist nicht |korrekt und funktioniert daher nicht. Verwenden Sie statt dessen die |folgenden Informationen für das Java-Beispiel:
|Das Beispielprogramm PluginEx.java befindet sich im |Unterverzeichnis samples/java. |PluginEx.java wird zusammen mit DB2 Application Development |Client installiert. Zur Kompilierung von |PluginEx.java müssen folgende Anweisungen in |classpath enthalten sein: |
|Erstellen Sie die Datei db2plug.zip mit allen Klassen, |die durch die Kompilierung von PluginEx.java generiert |wurden. Diese Datei sollte nicht komprimiert sein. Setzen Sie |z. B. folgenden Befehl ab:
| zip -r0 db2plug.zip PluginEx*.class
|Dieser Befehl nimmt alle CLASS-Dateien in die Datei |db2plug.zip auf und behält den relativen Pfad bei.
|Folgen Sie den Anweisungen in der Datei PluginEx.java, um |das Beispiel zu kompilieren und auszuführen.
|Die Schnittstelle CCObject enthält statischere Konstanten als die im Anhang |zur Erweiterung der Steuerzentrale im Handbuch "Systemverwaltung" |aufgeführten. Im Folgenden sind die Java-Schnittstellen zur Erweiterung |der Steuerzentrale aufgeführt (CCExtension, CCObject, CCM enuAction, |CCToolBarAction). Diese Schnittstellen dienen hier nur zur |Referenz.

In order | * for the Control Center to make use of these extensions, use the | * following setup procedures: | * (1) Create a "db2plug.zip" file which contains all the CCExtension | * subclass files. The files should not be compressed. For example, | * if the CCExtension files are in the plugin package and they are | * located in the plugin directory, issue | * zip -r0 db2plug.zip plugin\*.class | * This command will put all the plugin package class files into the | * db2plug.zip file and preserve their relative path information. | * (2) To run WEBCC as an applet, put the db2plug.zip file in where the | * <codebase> tag points to in the WEBCC html file. | * To run the Control Center as an application, put | * the db2plug.zip in a directory pointed to by the CLASSPATH | * envirnoment variable and where the Control Center is run. | * | * For browsers that support multiple archives, just add "db2plug.zip" | * to the archive list of the WEBCC html page. Otherwise, all the | * CCExtension, CCObject, CCToolbarAction, CCMenuAction subclass files | * will have to be in their relative path depending on which package | * they belong to. | */ | |public interface CCExtension |{ | /** | * Get an array of CCObject subclass objects which define | * a list of objects to be overrided in the | * Control Center | * @return CCObject[] CCObject subclass objects array | */ | public CCObject[] getObjects(); | | /** | * Get an array of CCToolbarAction subclass objects which represent | * a list of buttons to be added to the Control Center | * main toolbar. | * @return CCToolbarAction[] CCToolbarAction subclass objects array | */ | public CCToolbarAction[] getToolbarActions(); |} | |
