I think you'll have to use "exception#" instead of "exception", in order to generate a local symbol. Otherwise, the quoting will try to resolve "exception" in the current namespace.
Also, don't expand "~url" more than once -- what if the expression passed for "url" has side effects? It would get executed 3 times. -Steve On 25 Jan 2010, at 11:41, Manish wrote: > Hi, > I am new to clojure. I want to use try-catch block to the (.getPage > *wc* ~url) statement of code.
