JAR file format Wikipedia. A JAR Java ARchive is a packagefile format typically used to aggregate many Java class files and associated metadata and resources text, images, etc. JAR files are archive files that include a Java specific manifest file. They are built on the ZIP format and typically have a. A JAR file allows Java runtimes to efficiently deploy an entire application, including its classes and their associated resources, in a single request. JAR file elements may be compressed, shortening download times. A JAR file may contain a manifest file, that is located at META INFMANIFEST.

The entries in the manifest file describe how to use the JAR file. For instance, a Classpath entry can be used to specify other JAR files to load with the JAR. The contents of a JAR file may be extracted using any standard decompression software, or the jar command line utility jar xf foo. SecurityeditDevelopers can digitally sign JAR files.

A JAR Java ARchive is a package file format typically used to aggregate many Java class files and associated metadata and resources text, images, etc. In that case, the signature information becomes part of the embedded manifest file. The JAR itself is not signed, but instead every file inside the archive is listed along with its checksum it is these checksums that are signed. Multiple entities may sign the JAR file, changing the JAR file itself with each signing, although the signed files themselves remain valid. When the Java runtime loads signed JAR files, it can validate the signatures and refuse to load classes that do not match the signature. It can also support sealed packages, in which the Classloader will only permit Java classes to be loaded into the same package if they are all signed by the same entities. This prevents malicious code from being inserted into an existing package, and so gaining access to package scoped classes and data. The content of JAR files may be obfuscated to make reverse engineering more difficult. Executable JAR fileseditAn 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 my. Programs. My. Class and an explicit Class Path and the cp argument is ignored. Some operating systems can run these directly when clicked. The typical invocation is java jar foo. Native launchers can be created on most platforms. For instance, Microsoft Windows users who prefer having Windows EXE files can use tools such as JSmooth, Launch. J, Win. Run. 4J or Nullsoft Scriptable Install System to wrap single JAR files into executables. ManifesteditA manifest file is a metadata file contained within a JAR. It defines extension and package related data. It contains name value pairs organized in sections. If a JAR file is intended to be used as an executable file, the manifest file specifies the main class of the application. The manifest file is named MANIFEST. MF. The manifest directory has to be the first entry of the compressed archive. SpecificationseditThe manifest appears at the canonical location META INFMANIFEST. MF. 7 There can be only one manifest file in an archive and it must be at that location. The content of the manifest file in a JAR file created with version 1. Java Development Kit is the following. Manifest Version 1. The name is separated from its value by a colon. The default manifest shows that it conforms to version 1. The manifest can contain information about the other files that are packaged in the archive. Neuroph is lightweight and flexible Java neural network framework which supports common neural network architectures and learning rules. Last Site Update 18 March 2017 Stable Version 5.

Users who just want to run FitNesse by itself should download. Manifest contents depend on the intended use for the JAR file. The default manifest file makes no assumptions about what information it should record about other files, so its single line contains data only about itself. JAR files created only for the purpose of archiving do not use the MANIFEST. MF file. Most uses of JAR files go beyond simple archiving and compression and require special information in the manifest file. ApplicationseditIf an application is contained in a JAR file, the Java Virtual Machine needs to know the applications entry point. Jar-Ajar_1.jpg' alt='Download Jar File' title='Download Jar File' />An entry point is any class with a public static void mainString args method. This information is provided in the Main Class header, which has the general form. Main Class com. My. Class. Name. In this example com. My. Class. Name. main executes at application launch. Package SealingeditOptionally, a package within a JAR file can be sealed, which means that all classes defined in that package are archived in the same JAR file.

PlantUml allows to quickly create some UML diagram using a simple textual description language. A package might be sealed to ensure version consistency among the classes in the software or as a security measure. To seal a package, a Name entry needs to appear, followed by a Sealed header, such as Name my. Companymy. PackageSealed true. The Name headers value is the packages relative pathname. Note that it ends with a to distinguish it from a filename. Any headers following a Name header, without any intervening blank lines, apply to the file or package specified in the Name header. In the above example, because the Sealed header occurs after the Name my. Companymy. Package header with no intervening blank lines, the Sealed header applies only to the package my. Companymy. Package. Package VersioningeditSeveral manifest headers hold versioning information. One set of headers can be assigned to each package. The versioning headers appear directly beneath the Name header for the package. This example shows all the versioning headers Name javautilSpecification Title Java Utility ClassesSpecification Version 1. Specification Vendor Sun Microsystems, Inc. Implementation Title java. Sun Serial Port Configuration. Implementation Version build. Implementation Vendor Sun Microsystems, Inc. DependencieseditThe MANIFEST. MF file can be used to specify all the classes that must be loaded for an application to be able to run. Note that Class Path entries are delimited with spaces, not with the system path delimiter Class Path.
