J2PrinterWebStartTest Application
---------------------------------
Created with Xcode 3.1.1, Mac OS X 10.5.5. 
(For Windows, see "Win/J2PrinterWebStartTest".)

Brief Description: 
This sample demonstrates the use of the J2PrinterWorks class 
J2PrinterWebStart which enables J2PrinterWorks-based printing from Java 
Web Start applications. 

The following JNLP API is used by J2PrinterWebStartTest: 
PrintService: This interface provides methods for access to JNLP printing 
functions.  In particular, the methods showPageFormatDialog(PageFormat) and 
print(Pageable) are used.

Java Web Start is launched automatically by the browser when the user clicks 
on a link which is associated with JNLP file.  It then downloads and caches 
J2PrinterWebStartTest on the local client machine where the browser is running.
When invoked next time, this cached application is run without downloading 
and runs as fast as a traditionally installed application.  By default 
applications are run in a protective environment (sandbox) with restricted 
access to local disk and network resources.  Java Web Start only transfers JAR 
files from the Web server to the location determined by it on the client machine. 

For more details on Java Web Start product and JNLP API, please check the Sun 
online documentation at http://java.sun.com/products/javawebstart/developers.html 
or http://java.sun.com/javase/technologies/desktop/javawebstart/index.jsp. 

Files for Java Web Start (Mac OS X): 
bin         - This directory containing .class files is generated
              by the Xcode/Ant build process.
build       - This directory is generated by Xcode and contains 
              intermediate files.
build.xml   - This file is used by Xcode and Ant to build the application.
              It is kind of Makefile for the Ant tool.
dist        - This directory contains .jar, .html, and .jnlp files for 
              distribution to the target web site. 
J2PrinterWebStartTest.xcodeproj    - This file is the Xcode 3.1.1 project file. 
                                     Double-click this file to launch Xcode to 
                                     build and run J2PrinterWebStartTest.
jars        - This directory contains Xcode intermediate .jar files.
lib         - This directory contains .jar files required at compilation time.
              Place a copy of J2PrinterWorks.jar in this directory before 
              building the application.
readme.txt  - This file. 
resources   - This directory has the .html, .jnlp, and Manifest source files 
              required for J2PrinterWebStartTest. 
src         - This directory has the required Java source file: 
              J2PrinterWebStartTest.java 

Building & Testing J2PrinterWebStartTest (Mac OS X):
1) Place a copy of your 
      J2PrinterWorks.jar
   in the lib folder. 

2) Double-click the Xcode project file 
      J2PrinterWebStartTest.xcodeproj
   to launch Xcode. Verify that these files are present in the Xcode project:
          readme.txt
          build.xml
          src/J2PrinterWebStartTest.java
          resources/J2PrinterWebStartTest.html
          resources/J2PrinterWebStartTest.jnlp
          resources/Manifest
          lib/J2PrinterWorks.jar
          lib/jnlp.jar

3) The file
      build.xml
   installs files onto your local machine, in the user's default website 
   location "Sites"; you will need to turn on Web Sharing in System Preferences.
   A copy of J2PrinterWorks.jar must be in the lib folder.

4) In the file
      J2PrinterWebStartTest.html
   if necessary, modify the path to J2PrinterWebStartTest.jnlp in the href tag 
   to point to your web server location. This change should be needed only if 
   you modified the installation target location in the build.xml file.

5) In the file
      J2PrinterWebStartTest.jnlp
   modify the tag "codebase=" to point to the location on your web server
   where J2PrinterWebStartTest will be installed, e.g. 
      codebase="http://www.yourwebsite.com/J2PrinterWebStartTest"
   Save your changes.

6) Build and run J2PrinterWebStartTest with the Xcode Build and Go commands. 
   Ant is the external Java-based build tool used by Xcode for building this 
   application; for more information, check http://jakarta.apache.org/.

Deployment of J2PrinterWebStartTest:
Java Web Start applications may be installed on any J2EE-compliant server. 
   The resources required for this, including .jnlp and .jar files, may be 
   packed into a Web Archive (.war) file. For information on server deployment, 
   see the Sun web site and your server documentation.
