How to Load .net (VB) dll and use method in It in java

Question

I have a .net dll which has some functions that i need to call from a java program. This is the code that I have used which is giving me this error."Exception in thread "main" java.lang.UnsatisfiedLinkError:" but the dll loads fine. s

static {
        try {

            System.load("mydotnet.dll");
            System.out.println("loaded");

        } catch (UnsatisfiedLinkError e) {
            System.err.println(e);

        }
    }

    private static native boolean SC_Start();

the dll load well but accessing the function in the dll is giving this errror:Exception in thread "main" java.lang.UnsatisfiedLinkError — MorganM, Sep 25 '14 at 14:02
Anyway you cant just use Net dll. Java works with native dll's only. You need to wrap you Net dll into native one. — talex, Sep 25 '14 at 15:05

Is your DLL in a directory on the Java PATH?

If not, either:

Add the directory containing the DLL to the PATH
Move the DLL to a directory already in the PATH
Or use the full path to the DLL, eg C:\Path\To\Directory\mydotnet.dll

Is your DLL set up to be used by Java? Java can't just load and use any old .NET DLL See this answer for an explanation http://stackoverflow.com/questions/8675179/accessing-dll-methods-in-java – Jon Story Sep 25 '14 at 14:16
