Java interoperability

Hi, I am attempting to use Java interoperability. I have downloaded a dependency through Leiningen [com.jayway.jsonpath/json-path "0.9.1"] I import the dependency into a namespace (:import (com.jayway.jsonpath JsonPath) The Java class, JsonPath has a static method 'read&

Re: Java interoperability

It looks like the method exists to me: https://github.com/jayway/JsonPath/blob/master/json-path/src/main/java/com/jayway/jsonpath/JsonPath.java#L-445-505 It looks like the problem is that you are passing in empty strings: https://github.com/jayway/JsonPath/blob/master/json-path/src/main/java/com

Hi Jarrod > Any reason not to use a Clojure library like cheshire for JSON? Yes, I am probably taking the wrong approach. Is the Clojure way to put the JSON in Clojure data structures and manipulate it with filters etc? Many Thanks Paul On Mon, Jan 27, 2014 at 3:35 PM, Jarrod Swart wrote: >

Re: Java interoperability

The typical route I take is to always check http://clojure-toolbox.com first to see if a library exists. If not and it's a trivial thing I might just write it myself. My first thought is never, "Hey I should go grab a Java lib to do this." But typically yes JSON is extremely close to clojure

Java interoperability and Clojure

What are the limitations of Clojure and Java interoperability? Are they clearly stated somewhere? I have been experimenting with using Clojure to test some existing Java code (being able to do so makes a convincing argument to use it where I work) and I've noticed that there doesn't

Re: java interoperability: No such namespace error

I think you need a space before the final LogManager, not just a period: (ns de.uni-stuttgart.iaas.ipsm.base-resource-service.core (:import [org.apache.logging.log4j LogManager]) The vector's just for style, a list works just as well. Timur July 31, 2014 at 1:4

java interoperability : calling set! on several fields of the same instance

Hello, I want to call set! several times on a same instance, e.g. : (let [instance (SomeBeanCtor.)] (set! (. instance field1) expr1) (set! (. instance field2) expr2) ...) Do you know if a macro simplifying this already exists ? Anyway, I've created one as an exercise, and here it is: (def
