One of the most popular is Apache XML-RPC, an open source project managed by the
developers of the Apache web server, Tomcat Java servlet engine, Ant build tool, and
other popular open source software.
The Apache XML-RPC project, which consists of the
org.apache.xmlrpc
package and
three related packages, contains classes that can be used to implement an XML-RPC
client and server with a short amount of your own code.
The project has a home page at the web address
http://xml.apache.org/xmlrpc.
Today's
projects employ release 2.0.
To use this project, you must download and install an archive file that contains a pair of
JAR files:
xmlrpc-2.0.jar
and
xmlrpc-2.0-applet.jar
.
The installation archive is offered as a free ZIP download (suitable for Windows users)
and combined TAR/GZ format download (for Linux, UNIX, and Mac OS X users).
Download and unpack the archive files matching your operating system. The main folder
contains two JAR archives containing the Apache XML-RPC class libraries:
xmlrpc-2.0.jar
and
xmlrpc- 2.0-applet.jar
(the version number might be different
at the time you install it).
After you have unpacked the files, references to the three JAR files can be added to your
system's
Classpath
environment variable so that Apache XML-RPC's packages will be
found by your Java interpreter and compiler.
The full folder location and name of each file should be included somewhere in the
Classpath
. For example, on Windows, if the files were in
C:\jdk\xmlrpc\
xmlrpc-2.0.jar
and
C:\jdk\xmlrpc\xmlrpc-2.0-applet.jar
, the following text
should be appended to the end of the
Classpath
:
;C:\jdk\xmlrpc\xmlrpc-2.0.jar;C:\jdk\xmlrpc\xmlrpc-2.0-applet.jar
Semicolons separate each reference to a file or folder in the
Classpath
. The text is simi-
lar on a Linux or UNIX system, but you must use colons between files instead of semi-
colons:
20
:C:\jdk\xmlrpc\xmlrpc-2.0.jar:C:\jdk\xmlrpc\xmlrpc-2.0-applet.jar
Take care not to wipe out anything that's already in the
Classpath
. More information on
how to set up this environmental variable can be found in Appendix A, “Using the Java
Development Kit.”
