Hi,
These are the some info about jar file
The JavaTM Archive (JAR) file format enables you to bundle multiple files
into a single archive file. Typically a JAR file will contain the class
files and auxiliary resources associated with applets and applications.
The JAR file format provides many benefits:
Security:
You can digitally sign the contents of a JAR file. Users who recognize your
signature can then optionally grant your software security privileges it
wouldn't otherwise have.
Decreased download time: If your applet is bundled in a JAR file, the
applet's class files and associated resources can be downloaded to a browser
in a single HTTP transaction without the need for opening a new connection
for each file.
Compression: The JAR format allows you to compress your files for efficient
storage.
Packaging for extensions (version 1.2): The extensions framework provides a
means by which you can add functionality to the Java core platform, and the
JAR file format defines the packaging for extensions. Java 3D TM and
JavaMail are examples of extensions developed by SunTM. By using the JAR
file format, you can turn your software into extensions as well.
Package Sealing (version 1.2): Packages stored in JAR files can be
optionally sealed so that the package can enforce version consistency.
Sealing a package within a JAR file means that all classes defined in that
package must be found in the same JAR file.
Package Versioning (version 1.2): A JAR file can hold data about the files
it contains, such as vendor and version information.
Portability: The mechanism for handling JAR files is a standard part of the
Java platform's core API.
thanks,
vijay
