Externe Api einbinden

[tom g.]

Hallo Forum,

ich fange gerade an mit externen Api's zu proggen.
Jetzt meine Frage.

Die Api's liegen als Jar Datei vor. Wie binde ich diese ein.
Ich benutze Netbeans 3.6.

Die Api's sind JDIC und JCAPI.

Danke.

Tom

 

[bygones]

willst du wissen wie du sie in Netbeans oder generell nutzen kannst.

Ziel ist bei beiden das selbe, der Weg ist anders. In beiden Fällen müssen die jars im classpath liegen und die benötigten Klassen im Programm impotiert sein.

über path / classpath usw nutz die suchfunktion !

Hallo deathbyaclown,

beides würde ich mal sagen .

Als erstes wollte ich die Api's in NetBeans einbinden um die Examples zu Testen.

Dann natürlich um eigen Sachen zu Proggen.


Werde mal hier im Forum suchen.

THX

Tom

Hmmmm? ???:L

ich habe jetzt die beiden Jar Dateien mit in den jre/lib Ordner der SDK kopiert und den Pfad mit in den Classpath eingegeben.

C:\Dokumente und Einstellungen\*****>echo %CLASSPATH%
.;C:\Programme\Java\jdk1.5\jre\lib\rt.jar;C:\Programme\Java\jdk1.5\jre\lib\jdic.
jar;C:\Programme\Java\jdk1.5\jre\lib\jcapi.jar

Über Mount-->ArchivFiles habe ich die jdic.jar mit eingebunden. F9 funzt ohne Fehlermeldung.

Beim Ausführen erscheint folgender fehler:

Exception in thread "main" java.lang.NoClassDefFoundError: org/jdesktop/jdic/tray/internal/impl/ServiceManagerStub
        at org.jdesktop.jdic.tray.internal.ServiceManager.getService(Unknown Source)

}

Wo mache ich den Fehler?

Eine IDE scheißt (tschuldige für den Ausdruck, is aber so) meist auf die ClassPath UmgebungsVariable

Du musst in der IDE entweder selber das einstellen (classpath) oder in der IDE das zu deinem Projekt hinzufügen!

Gegebenenfalls probiers mal mit javac/java, dann sollte es funktionieren!
