IBM alphaWorks has released IBM Container for ActiveX Documents - Eclipse Version. "The Standard Widget Toolkit (SWT), a part of Eclipse Workbench, has its own standard ActiveX container. However, while holding and interacting with ActiveX documents, it gives sizing errors. This container is also rigid, insecure, and inextensible. In addition, since the complete event-handling mechanism is coded in Java, there are frequent context switches between native and Java run time that cause performance problems."
"IBM Container for ActiveX Documents (Eclipse Version) resolves these problems by providing a custom SWT component written on top of Microsoft Foundation Library (MFC), which comes with any standard version of Microsoft Windows."
