Problems with Java-Bindings on Win7 over COM/XPCOM

[torn8]

Hey guys,

I want to control my VBox on a Windows 7 machine with Java over COM/XPCOM.
I added vboxjxpcom.jar to my Classpath and I also set the vbox.home property correctly.

However I get the following error:

Code: Select all

Exception in thread "main" java.lang.UnsatisfiedLinkError: no vboxjxpcom in java.library.path
	at java.lang.ClassLoader.loadLibrary(Unknown Source)
	at java.lang.Runtime.loadLibrary0(Unknown Source)
	at java.lang.System.loadLibrary(Unknown Source)
	at org.mozilla.xpcom.internal.JavaXPCOMMethods.registerJavaXPCOMMethods(JavaXPCOMMethods.java:66)
	at org.mozilla.xpcom.internal.MozillaImpl.initialize(MozillaImpl.java:48)
	at org.mozilla.xpcom.Mozilla.initialize(Mozilla.java:669)
	at org.virtualbox_4_3.VirtualBoxManager.createInstance(VirtualBoxManager.java:110)
	at de.xxxx.tests.MainConnector.main(MainConnector.java:12)

It seems to me that he want to have a vboxjxpcom.dll in the lib-path, however I couldn't find a such file at SDK- or VBox-folder.

Do you have a suggestion for me?

Thanks a lot!

PS: My Java-Code:

Code: Select all

import org.virtualbox_4_3.IVirtualBox;
import org.virtualbox_4_3.VirtualBoxManager;


public class MainConnector {
   public static void main(String[] args) {
	   
	   
	   System.setProperty("vbox.home", "C:\\Program Files\\Oracle\\VirtualBox");
   VirtualBoxManager mgr = VirtualBoxManager.createInstance(null);
   
   IVirtualBox vbox = mgr.getVBox();
   System.out.println("VirtualBox version: " + vbox.getVersion() + "\n");

   // get first VM name
   String m = vbox.getMachines().get(0).getName();
   System.out.println("Attempting to start VM " + m);

   // start it
   //mgr.startVm(m, null, 7000);
   mgr.cleanup();
   }
}

VBox + SDK - Version: 4.3.6-91406

XPCOM is for everything except Windows. (MS)COM is what you need for Windows. Read section 1.2 & 2.3 of the SDK PDF.

Thx a lot for your reply, noteirak.

I also tried to do it this way, however I couldn't find the vboxjmscom.jar-file. Where is it located?

[noteirak]

AFAIK there are no Java binding for MS COM, but I never used MSCOM so I can't tell you precisely. At least, nothing like that is found in the SDK package, and I always went the webservices route while being on Windows.
There is a sample file inside the SDK ZIP under /sdk/bindings/mscom/samples, and it seems to only use COM & C/C++.

I've found a solution.

You have to compile VBox with VBOX_WITH_JMSCOM=1.

Can anybody provide a valid vboxjmscom_4.3.jar-file? I don't want to compile VBox just because of this file...

Thank you very much in advance.

Oh nice one, wasn't aware of this build option. For the jar, you're better of asking directly on the dev mailing list, so you get an official build jar, instead of a SVN one.
