Daniel. Thank you for your response - some 2 years ago, I know. So, I upgraded my Java/Clojure applet to use dtjava.embed() and a JNLP-file. And the problem got worse. Now the loader was hitting the server 10 times(!) for every Clojure-file - also the ones that were included in the JAR.
So I actually figured out how to build Clojure from source myself and fiddle with your suggestion. :-) First off, by setting cljURL to null categorically prevented Clojure from not even building. So I tried some different things, only to find out the problem lay in the very first lines of the load-function - in the calls to getResource(). This caused the JNLP2ClassLoader to first hit the server many times before getting the requested resource from the already downloaded JAR-file. The solution was as simple as to add an index to the JAR! See here: http://stackoverflow.com/questions/19187209/jnlp2classloader-findclass-requests-from-server-multiple-times-before-checking-j/19189127#19189127 As for the user.clj, I simply put an empty one into the jar at the top level. kl. 18:33:33 UTC+1 torsdag 17. november 2011 skrev Daniel Solano Gómez følgende: > > On Thu Nov 17 09:06 2011, Terje Dahl wrote: > > What is the relationship between the .clj source-file(s) and its gen- > > class compiled class-files? > > > > The reason I ask is that my app is an applet, written in Clojure > > (obviously), and compiled. > > The resulting class-files are then bundled into a jar-file, but > > without the source clj-file. > > (I don't want to incude my source-code in the deployed applet jar-file > > - for business reasons, obviously). > > > > The applet loads and runs just fine, but not before requesting clj- > > files from the server. > > In my server log files I see failed requests for "user.clj" and > > "applet.clj" (the file containing all my source-code). > > The applet doesn't recieve the files from the server, but runs just > > fine all the same, so obviously doesn't need them. > > > > 1.
