JACOB is a JAVA-COM Bridge that allows you to call COM Automation components from Java. It uses JNI to make native calls into the COM and Win32 libraries. The JACOB project started in 1999 and is being actively used by thousands of developers worldwide. As an open-source project, it has benefitted from the combined experience of these users, many of whom have made modifications to the code and submitted them back for inclusion in the project.
