    Hi,

    First, I've to say sorry for my english ability.
    I'm new in working with external .jar file. May anyone can guide me how to work with it?

    Suppose I've a .jar file (for example CRC.jar). It contains CRC16.class and CRC32.class.
    In CRC16.class, there is a function

    public static short calcrc16(byte[] data, int len)

    How can I call and get result from calcrc16?

    I've added
    #AdditionalJar: CRC
    in my test application. After that I added a sub

    Sub GetCRC16 As JavaObject
    Dim jo As JavaObject

    End Sub

    Please anyone guide me what to do next.

    Best Regards,
    Piyapong.

    Code:
    Dim jo As JavaObject
    jo.InitializeStatic(
    "package.name.which.you.didnt.provide.CRC16")
    log(jo.RunMethod("calcrc16"Array (Array As Byte(1234), 4))
