Class-Path describes the location of supportLib.jar relative to the location of the library helloWorld.jar. Neither absolute file path, which is permitted in -classpath parameter on the command line, nor jar-internal paths are supported.
Download the installer from WMFLabs (don't worry if there's a warning, .jar files are supposed to be executable files) Run the installer (if Java is correctly installed and configured, opening the downloaded jar file should run the installer [1]) Provide the required information for the configuration:
An executable Java program can be packaged in a JAR file, along with any libraries the program uses. Executable JAR files have the manifest specifying the entry point class with Main-Class: myPrograms.MyClass and an explicit Class-Path (and the -cp argument is ignored). Some operating systems can run these directly when clicked.
The virtual machine will only load the class files required for executing the program. [2] The Java run time system does not need to know about files and file systems as this is delegated to the class loader. A software library is a collection of related object code. In the Java language, libraries are typically packaged in JAR files. Libraries ...
Almost all of JCL is stored in a single Java archive file called "rt.jar" which is provided with JRE and JDK distributions. The Java Class Library (rt.jar) is located in the default bootstrap classpath [ 1 ] and does not have to appear in the classpath declared for the application.
A sample build.xml file is listed below for a simple Java "Hello, world" application. It defines four targets - clean, [15] clobber, compile and jar, each of which has an associated description.
