classpath

I have a runnable jar with two jars in the Class-Path entry of its manifest file: Class-Path: module1-0.0.1-SNAPSHOT.jar base-0.0.1-SNAPSHOT.jar Main-Class: test.MySPI The program runs fine and all dependencies in the referenced jars are met. However, when I try to access the class path, the jars are not there: String classpath = System.getProperty("java.class.path"); String[] entries = classpath.split(System.getProperty("path.separator")); for (String entry : entries) { System.out.println("Entry: " + entry); } Only gives Entry: .\module2-0.0.1-SNAPSHOT.jar Is there a way of accessing the

I'm developing an Eclipse SWT application using Eclipse. There are also some JUnit 4 tests, which test some DAO's. But when I try to run the tests via an ant build, all of the tests fail, because the test classes aren't found. Google brought up about a million of people who all have the same problem, but none of their solutions seem to work for me -.- . These are the contents of my build.xml file: <property name="test.reports" value="./test/reports" /> <property name="classes" value="build" /> <path id="project.classpath"> <pathelement location="${classes}" /> </path> <target name="testreport"

I have a C binary that calls out to Java via JNI. I set CLASSPATH to somedir/* to pick up all the jars in somedir. When I run the binary, a required class definition cannot be found. When I run java that.class's.name from the same command line, the class is successfully found. If I explicitly add all the jars in somedir/ to the classpath, everything works great, but that leads to a very long classpath which I'd like to avoid. Does a JVM executed via JNI honour wildcard expansion of the classpath? Can it be made to do so? I figured out the answer by reading the hotspot source code. Only paths

I've heard that you can use classpath to use classes in other libraries. I googled about this and all results tell me to use the command line to compile the program and specify a classpath. But who would use command line to compile java programs nowadays? I am using eclipse and Android Studio. I mean they are IDEs so they surely can set the classpath very easily, right? Also, I want to know the word "library" in this context is just a jar file , right? Sumit Singh In Eclipse: Right-Click on the Project → Build Path → Configure Build Path . Under Libraries tab, click Add Jars or Add External

I'm trying to look under the hood about java compilation. So I put my IDE away and started using MS-DOS command-line... I created a simple project, as described in the tree below : SampleApp |____**src** |_____pack |______Sample.java |____**classes** This is the Sample.java source code : public class Sample { private String s = new String("Hello, world"); public Sample(){ System.out.println(s); } } I just want to compile this class, so I used the javac command : prompt\SampleApp\src>javac -d ..\classes -sourcepath . pack\Sample.java All works fine, but i didn't expect that because I deleted my
