Will there be any issue if we use the same package in multiple rulebases? I saw a comment in one of the posts which states - "Just make sure the only thing you eventually share among threads is the rulebase. Do not share session or packages among threads." http://www.nabble.com/Multithreading-Rulebase-Parsing-Threadsafe-td172399... Why do we say that packages should not be shared among threads? If we are only creating the rulebase from the package, how does it matter? Thanks, Seema -- View this message in context: http://www.nabble.com/Sharing-packages-among-rulebases-in-JEE-app-tp19904...
