Hi Colin, One of the compromises Ring makes for efficiency is that the body of a request is an InputStream, rather than a static string or byte array pre-loaded into memory. Because it's a stream, it can potentially be consumed by previous middleware.
For some reason you have both wrap-json-body and wrap-json-params in your stacktrace: ring.middleware.json$wrap_json_body$fn__1031.invoke(json.clj:19) ring.middleware.json$wrap_json_params$fn__1035.invoke(json.clj:31) Both middleware read from the body InputStream, so one of them is going to fail when you try and read the body twice. - James On 4 November 2013 00:20, Colin Yates <colin.ya...@gmail.com> wrote: > Hi all, > > I have developed a ring/compojure app which receives and servers JSON. > All is well in 'lein ring server' but as soon as I do 'lein ring uberwar' > and deploy it to tomcat 6 or 7 it fails.
