jacoZoom - Java-COM-Bridge
: What is jacoZoom ? :

jacoZoom is a tool for programmers and not for end users!

jacoZoom is a java class library which allows you to use ActiveX Controls and ActiveX Servers (COM/DCOM/Automation) with java. It is based on JNI and thus can be used with any java environment on the MS Windows platform.

jacoZoom contains a typelibrary parser, which produces java wrapper classes directly corresponding to the COM-objects and interfaces.
: Features of jacoZoom :
  • Embedding of ActiveX Controls in java user interfaces
  • Embedding of OLE Documents in java user interfaces
  • Support of both COM method-calling mechanisms: vTable and dispatch interfaces
  • Event handling support for COM events
  • Smart code generation for Java wrapper classes with method overloads for optional parameters
  • New dialog frontend for generating wrapper classes, compiling them and creating JAR with them
: Download - free for evaluation :

You can download the fully functional jacoZoom version for test purposes, but you may not use it in commercial projects before purchasing a license.

After using jacoZoom for 30 days, each time jacoZoom is started, a message box is displayed, asking you to consider purchasing the product.

But this does not impair the functionality of the software, which continues to work after the 30 day limit, only the message box is displayed until a license key is purchased and installed.

Download jacoZoom for JDK 1.1, 1.2, 1.3, 1.4.x, 1.5, 1.6



If you want to download jacoZoom in form of jacozoom.zip for manual installation, please click here. But note, that then you won't get shortcuts in the Program-Menu for starting the new jacoZoom dialog frontend.
