Jon, Any ideas on this please? I'm using the exact code you provided in the
previous posts.

Hi Jon,
So using the above code that you posted is working for me, but the
constructor to my .java object is being called multiple times and is
producing some strange behavior. How many instances of my java object are
created with the above code? Is it calling my object constructor more than
once

Depends on what "something useful" is. JavaArray implements IList; isn't
IList useful? ;-)
If you'd prefer a byte[], you could use LINQ's .ToArray() extension method.
Alternatively,
Woo Hoo, thanks Jon! My problem was that I was calling YourJniHelper instead
of instantiating MyJniHelper. The callback is now received. Now how do I
convert that JavaArray cardData to something useful?
Thanks

It would be handy to have the .jar file to test against (or something with the
same API). That said..

Jon,
First, thanks for all your help on this, its gotten me pretty far.
I used your code to call the jni_helper and initialize the reader; however,
the manged wrapper for the onReceiveMsgCardData() is never called. You were
right in assuming that the 'uniMagReader' instance calls the
onReceiveM

My question from before remains the same: what code is calling
onReceiveMsgCardData()
Hi Jon,
Thanks for your help. Based on the exception info I was able to fix the
issues with the .java code and can now call the methods via JNI. I still
have the issue of the callback though. What happens in the .java code is
that when a hardware event occurs it fires the onReceiveMsgCardData() ev

An exception is thrown. Exception.ToString() will also print out the Java-side
message and stack trace. Throw the code within a try/catch(Exception
Hi Jon,
An update to my previous post...
I looked into that sanity check code and updated my code based on it's
example.
IntPtr helperClass = JNIEnv.FindClass("MagHelper/jni_helper");
IntPtr ctor = JNIEnv.GetMethodID(helperClass, "", "()V");
IntPtr methodId = JNIEnv.GetMethodID(helperClass, "Ini
Hi Jon,
First, thank you for taking the time to create such it a detailed response,
it's greatly appreciated
Based on what you said, I've made the ctor public in the .java file.
I then changed my JNI code to this, but I get an error on the
JNIEnv.GetMethodID call.
IntPtr _helperClass = JNIE

The SanityTests sample has a more complete example of JNI use:
