Hi Guys!
Somebody please help me to get this code to work (the project and library is attached)

B4X: 
#Region Project Attributes
    #MainFormWidth: 600
    #MainFormHeight: 600
    #AdditionalJar: c:\stuff\jacob\jacob.jar
#End Region   

Sub Process_Globals
    Private fx As JFX
    Private MainForm As Form
End Sub

Sub AppStart (Form1 As Form, Args() As String)
    MainForm = Form1
    MainForm.Show
    Dim jjo As JavaObject = Me
    jjo.RunMethod("cnct1c",Null)
End Sub

#If JAVA
    import com.jacob.activeX.ActiveXComponent;
    import com.jacob.com.ComFailException;
    import com.jacob.com.Dispatch;
    import com.jacob.com.Variant;
    import java.lang.String;

    public static void cnct1c() {

        ActiveXComponent v8 = new ActiveXComponent("V83.COMConnector");
        String conString = "File=d:\\1cbase\\auto;Usr=Admin;Pwd=";
        Variant connection = Dispatch.call(v8, "Connect", conString);
        return;
    }
#End If

It throws error:

This is a different error. Looks like you are not using the API correctly.

Oooo...Solved!
"V83.COMConnector" lib was 32bit so I just changed JDK to 32bit.

PS. For those who want to use JACOB to integrate with 1c (actual for russian users mostly) - JACOB (and other COM connectors dont work with 1c version 8.3). It fails when connecting to "V83.COMConnector" because of backbas.dll and comcntr.dll of 1c.
It throws errors:

Event: 0.038 Thread 0x00921000 Exception <a 'java/lang/NoSuchMethodError': Method sun.misc.Unsafe.defineClass(Ljava/lang/String;[BII)Ljava/lang/Class; name or signature does not match> (0x0f206eb8) thrown at [C:\ws\workspace\jdk-8u252\label\windows-x86\type\b8\build\hotspot\src\share\v

Event: 0.038 Thread 0x00921000 Exception <a 'java/lang/NoSuchMethodError': Method sun.misc.Unsafe.prefetchRead(Ljava/lang/Object;J)V name or signature does not match> (0x0f207188) thrown at [C:\ws\workspace\jdk-8u252\label\windows-x86\type\b8\build\hotspot\src\share\vm\prims\jni.cpp, l

So as Im understood if someone could recompile JACOB to accept this functions it could work..

But "V83.Application" works well.
