A few weeks back v18.104.22.168 of WebSphere ILOG JRules was released. This updated release addresses an issue that prevents the installation of add-ons on top of Rule Studio when installed in a dedicated Eclipse IDE. This fix pack is for licensed users of JRules V7.0.x and V7.1.x. Follow these instructions to install V22.214.171.124.. To download your free 90-day trial, all you need to do is complete the short registration form, select your operating system (Unix, Windows, or MAC OS) and download WebSphere ILOG JRules. All of the WebSphere ILOG business rules product features are enabled during the trial period. When you download this trial, you are also entitled to submit technical problems and questions through our WebSphere ILOG BRMS technical forum.
Instructions to install WebSphere ILOG JRules V126.96.36.199 were posted by the WebSphere support blog. I also recently discovered a great resource on developerWorks for the WebSphere ILOG JRules v188.8.131.52 Trial. This page provides additional details on the trial, support information, and product documentation for the WebSphere ILOG JRules family. I highly recommend checking it out.
