classpath

问题 Hopefully my issue isn't too silly but I'm having the following problem... I'm importing a jar which contains the library JmDNS into my project. My project sets up to handle JmDNS like this... setUp(); try { peer = new PublicPeer("Aidan",6666,6667,this); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } private void setUp(){ android.net.wifi.WifiManager wifi = (android.net.wifi.WifiManager) getSystemService(android.content.Context.WIFI_SERVICE); lock = wifi

问题 CLASSPATH has the "/Users/smcho/Desktop/clojure" as one of its path, and this directory has the file hello.clj. Running clojure, and running (require 'hello) give this error message. java.io.FileNotFoundException: Could not locate hello__init.class or hello.clj on classpath: (NO_SOURCE_FILE:0) When I change directory to "/Users/.../clojure", and run the same (require 'hello), there's no problem. The . is on the CLASSPATH. Running java -cp /Users/smcho/bin/jar/clojure.jar:/Users/smcho/Desktop

问题 I have a jar file foobar.jar containing the following two classes: public class Foo { public static void main(String[] args) { System.out.println("Foo"); } } The other class looks like this: import javax.batch.api.chunk.ItemProcessor; public class Bar implements ItemProcessor { public static void main(String[] args) { System.out.println("Bar"); } @Override public Object processItem(Object item) throws Exception { return item; } } If I execute the program using the following command, the

问题 java version "1.5.0_14" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_14-b03) Java HotSpot(TM) Server VM (build 1.5.0_14-b03, mixed mode) I'm trying to debug a NullPointerException I'm getting for passing a reference to statically defined field. To be more specific, I'm setting a global on a Drools3 working memory instance. workingMemory.setGlobal("log", workingMemorieslog); My assumption is that the Class where the field is statically defined is being garbage collected.

问题 I have a maven project, that I'm working on Eclipse. I use maven eclipse:eclipse to generate the classpath, but ... it NEVER adds the classpath on the eclipse project. I've tried the maven-eclipse-plugin, I've tried the M2Eclipse plugin, but it doesn't matter what I do, I can't get the classpath entries to start working. I have many build errors, even thought the maven builds the ear perfectly. Any guidelines? Thanks for any answer! UPDATE: Here's my root classpath: <?xml version="1.0"

问题 I was writing a small application and when I tried to create an ImageIcon I always got an exception. The exception was caused by this line of code: prayerLevel.setIcon(new ImageIcon(getClass().getResource("/icons/icon_prayer.png"))); Now within my program, the folder /icons/ does exist. I don't know if it makes the difference but the class file is within a package, where as the icons folder is within the project folder (when you would see the bin and src folder). I have looked around for a

问题 I am new to Gradle and I am reading the documentation but I don't understand some parts of it. One of these parts is connected with buildscript block. What is its purpose? If your build script needs to use external libraries, you can add them to the script's classpath in the build script itself. You do this using the buildscript() method, passing in a closure which declares the build script classpath. buildscript { repositories { mavenCentral() } dependencies { classpath group: 'commons-codec

问题 Ok I am on Win Vista and correctly set my MAVEN_HOME, JAVA_HOME stuff. but I do not have a class path yet. I have also installed MySQL. now I have opened a Hibernate book and at the very first pages it says "make sure the jdbc driver is in your classpath" .
