问题 I've been trying to compile a very simple test.clj in Clojure without any success. I have a thread on the Clojure Google Group with several responses, but nothing has helped. To quickly summarize, here is my clojure file: (ns test.test (:gen-class)) (defn -main [gre] (println (str "Hello " gre))) Basically it's the example file provided in the Clojure documentation. I have placed this file appropiately in clojure/src/test/test.clj , and should be able to compile with (compile 'test.test) ,

问题 I have a "core" application that is adapter to process task. Each task is implemented in an adapter load by the core to process the task. My question is, is it possible to have different classpath in each adapter to precent class/jar conflict between adapters. Regards, 回答1: Indeed: URLClassLoader cl = new URLClassLoader(urls); Thread thread = new MyThread(); thread.setContextClassLoader(cl); thread.start(); 回答2: Use Thread.currentThread().setContextClassloader() and make a new URLClassLoader

问题 I'm having a rather strange problem caused by both the facts that the android java implementation differs from the sun java implementation and that the base java classes are still included in the classpath (all the way at the end) during a maven build of an android project.

问题 I have developed an RCP plug-in (not standalone), and a Java Project with library code that the plug-in needs to call. I have configured the Java Project in the same workspace. The plug-in has a project dependency on the Java Project. The code compiles (the plug-in does some stuff with the Java Project / library code). When I run the plug-in, I get a ClassNotFoundException: java.lang.ClassNotFoundException: com.mycode.ArgSet at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal
