JEXL – A simple expression evaluation engine
February 15, 2009 3 Comments
When I was developing a framework looking for a solution very similar to eval() function in JavaScript. Initially I thought of Velocity but somehow I wasn’t convinced with that approach. (Struts2 uses Velocity to externalize the HTML generation to make it customizable). Later I wrote my own parser to evaluate an expression that returns a Boolean value. Recently I found an open source which exactly meets my requirement. I don’t have to talk much about this open source you can find lot more information in their website. I thought it might be useful to others as well.
