    Determining the API of the target application

    +Jacob is a Java library that lets Java applications communicate with Microsoft Windows +DLLs or COM libraries. It does this through the use of a custom DLL that the Jacob +Java classes communicate with via JNI. The library and dll isolate the Java developer +from the underlying windows libraries so that the Java developer does not have to write +custom JNI code. +

    +Jacob is not used for creating ActiveX plugins or other moduless that +live inside of Microsoft Windows applications. +

    + +

    The Jacob Packages

    +

    +The JACOB jar contains two main packages: the com.jacob.com.*> package and +the com.jacob.activeX package. The com.jacob.com.* package contains classes +map very closely to the com dispatch model with the com.jacob.com.Dispatch +acting as the primary communication class. Dispatch operate as a function library with +a set of static methods that map very closely to the C++ Dispatch APIs provided +to the COM layer. +

    com.jacob.activex.ActiveXComponent can be used in place of Dispatch +to provide a more object like API. +The only exception to this guideline is that the ActiveXComponent class is always +used to make the initial connection to the target dll/COM component. + +
