java.lang.UnsatisfiedLinkError

Dominicana · 19. Mai 2007

Hallo Java-Gemeinde

Habe mir vor ein paar Tagen eine USB-Relais-Karte von Quancom zugelegt (zum Schalten von bis zu 8 Niederspannungssignalen mit einer Spannung bis 30V oder 1A durch einen PC). Das mitgelieferte Programm funktioniert, ist aber nicht für meine Ansprüche ausgelegt. Mitgelieferte Programmierbeispiele (in C/C++, VB, Delphi, Java) versprechen viel, halten aber wenig, jedenfalls in Java.

QUANCOM Measurement and Automation boards:

This sample shows how to program the USBREL8/LC Card under Sun Java for Windows. This part of the sample writes to the outputs or relays.

Install the QLIB32 on your system and compile the file "DIGITAL_OUT.JAVA" with the java compiler. This project was intended to run under Sun Java for Windows.

Check www.quancom.de/qlib for updates.

Step1: Compile file

javac digital_out.java

Step2: Run file

java digital_out

digital_out.java :

Code:

		}
}

Das war erstmal der Java-Code. Die qlib32.dll ist in C:\Windows\System32 installiert, trotzdem bekomme ich :

java.lang.UnsatisfiedLinkError: QAPIExtOpenCard

Wenn mir jemand bei der Lösung des Problems helfen könnte, würde ich mich sehr freuen! Dom.

Wann die Exception auftritt kannst du hier nach lesen:
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/UnsatisfiedLinkError.html

Dominicana · 19. Mai 2007

Hmm.... da steht das selbe, wie in meinem Kompendium :

Ausgeworfen, wenn die Java Virtual Machine eine passende Native-Language-Definition von einer native deklarierten Methode nicht finden kann.

Aber wieso kann die JVM die >Native-Language-Definition< nicht finden? Wie/wo muß ich sie definieren/deklarieren?

madboy · 19. Mai 2007

nur n Schnellschuß aber vielleicht musst du das (ganz unten in qlib32)

Code:

   static    { 
      System.loadLibrary("qlib32");    // win32: qlib32.dll                                                
      }

ändern weil du ein "win32"-System hast (was auch immer das bedeuten mag :wink: ).

Gruß,
madboy

Dominicana · 20. Mai 2007

Wikipedia:

Win32 ist eine beliebte Abkürzung für die teilweise oder komplett 32-Bit-basierten Microsoft-Windows-Betriebssysteme Windows 95 (16/32 Bit), Windows 98 (16/32 Bit), Windows ME (16/32 Bit), Windows NT ab Version 4.0 (32 Bit), Windows 2000 (32 Bit), Windows XP (32/64 Bit) und Windows Vista (32/64 Bit).

Bloß gut, daß da nicht //win128: qlib128.dll stand :wink:

madboy · 20. Mai 2007

Danke, schon wieder was gelernt! Sollte mir wohl auch n Windows installieren dass ich mitreden kann :wink:
Aber das ist ja das Schöne an Java: Menschen aller Betriebssysteme können sich treffen und mehr oder weniger (wie meiner grad) Kommentare von sich geben.

Bloß gut, daß da nicht //win128: qlib128 stand

Hehehe, das dauert hoffentlich noch n Jährchen oder zwei.

Dir auf jeden Fall noch viel Erfolg!

Gruß,
madboy
