classpath

I'm using Netbeans 7.2.1 in Ubuntu 12.10 and I'm trying to change the order of class loading. I have two classes in same package with the same name, but one is in my sources and the other one is in a JAR. The class in my project sources has a higher priority and I want to use it instead of the class in the JAR. In Eclipse I can change the order under the "Order and export" tab in Project Properties -> Java Build Path. Netbeans seems to priorize JAR classes higher than project sources by default. How do I change the class loading order? Note: I discovered the answer while I was writing the

I am having some trouble running a few jar's on a linux box. Basically, I am getting an error saying it cannot find the main class of my main jar. The class is defenetly present so it must be a classpath issue. I am not great with linux, so I am looking for some advice as to where I might be missing something. First off, I am setting the classpath in the users bash_profile; adding all the jar's required, seperated by a : delimeter. I then export the classpath. Then, in the shell (ksh) script I use to invoke the main jar, I also st the classpath and call it in the command using -cp so it looks

I built a package called "com.hello" in eclipse and I wrote an easy HelloWorld program. Eclipse automatically added "package com.hello;" on top of my program. And HelloWorld.java was put in F:\workspace\helloWorld\src\com\hello; HelloWorld.class was put in F:\workspace\helloWorld\bin\com\hello. It worked very well in Eclipse. But when I entered the directory " F:\workspace\helloWorld\bin\com\hello " and used command line with "java HelloWorld," I got NoClassDefFoundError . I know it may have something to do with the classpath. But I'm not quite sure. Your class is in a package com.hello . To

I recently opened a Maven project with the pom.xml file: <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.example</groupId> <artifactId>demo</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>demo</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId

I just started writing Applets and I had some questions about the HTML applet tags with packages, and class files. I'll start with packages. I've been using Netbeans to code my applets, which includes a package automatically. The applet runs fine in the Netbeans applet viewer, and the HTML is displaying everything it should except the applet - there's just a white box that says "Error." When I re-compiled using Eclipse without the package, the HTML display the applet fine. I tried everything I could think of, but I could not for the life of me get the applet to work with the package. <applet

I have this Java code which I am using to run a python script using Jython ScriptEngine : StringWriter writer = new StringWriter(); ScriptEngineManager manager = new ScriptEngineManager(); ScriptContext context = new SimpleScriptContext(); context.setWriter(writer); ScriptEngine engine = manager.getEngineByName("python"); engine.eval(new FileReader("/Users/folder1/test.py"), context); In my python script there are several module import statements and when I run the Java code I get error as javax.script.ScriptException: ImportError: No module named psycopg2 . All the modules are installed in my

I have seen this posted a couple of times and tried a few of the suggestions with no success (so far). I have a maven project and my properties file in on the following path: [project]/src/main/reources/META_INF/testing.properties I am trying to load it in a Singleton class to access the properties by key public class TestDataProperties { private static TestDataProperties instance = null; private Properties properties; protected TestDataProperties() throws IOException{ properties = new Properties(); properties.load(getClass().getResourceAsStream("testing.properties")); } public static

I've specified the main class and classpath for a java program in the .jar file manifest, but occasionally I want to run a different class from the one specified by the Main-Class attribute. Can I get java to launch this class while still pulling the classpath from the manifest, so that I don't have to specify the whole thing on the command line with -cp ? Just put the jar file on the command line with -cp; Java will then observe the classpath attribute within the manifest, even though you're not using -jar: java -cp app.jar MyOtherClass 来源： https://stackoverflow.com/questions/7637820/run-java
