Ask anyone who’s had to work with JSON in Java: consuming, querying, and validating JSON objects in Java is a tedious chore. Either you’re stuck writing structured beans mapped to JSON responses, which is time-consuming and brittle, or you need to resort to circumlocutious chains of get() calls with typecasting (or foreknowledge of types) at every step. In particular, there is no equivalent (or even approximation) of XML’s XPath — until now.  JPath allows for concise, flexible navigation and validation of JSON data.  Check it out over at BLC.
