Sorry, I'm a bit in a hurry ;-) You give a vector, it needs an array. Try something like:
spels=> (make-array (.getClass "") 2 ) #<String[] [Ljava.lang.String;@ad8659> spels=> (def arr (make-array (.getClass "") 2 )) #'spels/arr spels=> (aset arr 0 "write") "write" spels=> (aset arr 1 "c:\\config.sys") "c:\\config.sys" spels=> (.exec (Runtime/getRuntime) arr) Greezs, alux Tim Daly schrieb: > The call I coded works if you only pass a string with no spaces. > > However, if the string has spaces there is no result. > If you break the string into String[] then clojure cannot match the > appropriate exec(String[]) method in Runtime.
