  Examples of non-functional Java platforms:
  • Kaffe

1. If you haven't already, download Java Web Start

   http://java.sun.com/cgi-bin/javawebstart-platform.sh

   and then install it. Make sure it works by trying out some of the demos, which you can find at

   http://java.sun.com/products/javawebstart/demos.html

2. Go to the Praya download page

   http://praya.sf.net/download.html

   Click on "Any Platform" (using java web start).

3. The Java Web Start splash screen should display for a while.

4. Java Web Start will then download jar files from praya.sourceforge.net if you don't already have them.

5. If this is the first time that you are using the Web Start launcher for praya, a dialog box will appear that looks something like this:

   This application is requesting unrestricted access to your local machine and network. Do you want to install and run: Praya Signed and distributed by: Praya Build Process Warning: Failed to verify the authenticity of this certificate. No assertions can be made of the origin or validity of the code. It is highly recommended not to install and run this code. [Start] [Details] [Exit]

6. If you want to use the Java Web Start strategy for launching Praya, go ahead and click "Start," in spite of the dire-looking warnings. If you would like to donate money toward getting rid of that dire warning box (it will take $200 to get a developer certificate from Thawte), please contact me at wtanaka@users.sourceforge.net, or use the Amazon Honor System (http://s1.amazon.com/exec/varzea/pay/T1CK3CH9X2S3UO) to contribute.

   

7. After running the program successfully once, you will no longer need to download the same jar files again.

1. If you don't already have a program to unpack .zip files, download Winzip from

   http://www.winzip.com/

   and install it.

2. Download the Any Platform (.zip file) from the download page.

   http://praya.sf.net/download.html

3. Unzip the praya package file that you just downloaded into a directory, for example, your desktop.
4. A folder named praya-x.yy will appear (where x.yy is the version number of praya)

   Praya is now installed. To run praya:

5. Open the praya-x.yy folder
6. Launch "praya.jar" (it is probably labeled "praya")

If you do not have Java 1.2 or higher installed on your machine, you have a few choices:

1. Get a Java Virtual Machine by yourself
   1. Download and install the Java Runtime Environment. This can be found at: http://www.javasoft.com./j2se/1.3/jre/download-windows.html
   2. Now, follow the directions above, because you already have Java 1.2 or higher installed on your machine.
2. Use a bundled JRE package
   1. If you don't already have a program to unpack .zip files, download and install Winzip

      http://www.winzip.com/

   2. Download one of the Windows (bundled with JRE) packages from the download page.

      http://praya.sf.net/download.html

      Save it in a directory, for example, on your desktop.

   3. Unzip the praya package file that you just downloaded into a directory, for example, your desktop.
   4. A folder named praya-x.yy will appear (where x.yy is the version number of praya)

      Praya is now installed. To run praya:

   5. Open the praya-x.yy folder
   6. Launch "praya.bat" (it is probably labeled "praya")

1. Use the rpm version
   1. Download the Linux Architecture-Independent RPM from the download page.

      http://praya.sf.net/download.html

   2. Open a terminal window
   3. Change into the directory containing the RPM. For instance, if you downloaded the RPM into /tmp, execute the following command:

      cd /tmp

   4. Become the super-user

      su

   5. Install the RPM:

      rpm -Uvh praya-*.noarch.rpm

   6. Exit the super-user shell:

      exit

   7. Run the program:

      praya

2. Use the .tar.gz or .tar.bz2 version
   1. Download the Any platform (.tar.gz file) or Any platform (.tar.bz2 file) from the download page.

      http://praya.sf.net/download.html

   2. Open a terminal window
   3. Change into the directory containing the RPM. For instance, if you downloaded the RPM into /tmp, execute the following command:

      cd /tmp

   4. Unpack the archive:

      .tar.gz command:

      gzip -dc praya-*-java.tar.gz | tar xvf -

      .tar.bz2 command:

      bzip2 -dc praya-*-java.tar.bz2 | tar xvf -

   5. Run the program:

      java -jar praya-*/praya.jar

If you do not have Java 1.2 or higher installed on your machine:

1. Open a terminal window
2. Download JRE 1.3 for Linux (these instructions assume that you get the RedHat RPM shell script)

   http://java.sun.com/j2se/1.3/jre/download-linux.html

3. Change into the directory containing the RPM. For instance, if you downloaded the RPM into /tmp, execute the following command:

   cd /tmp

4. Become the super-user

   su

5. Install the Java RPM:

   rpm -Uvh j2re-1.3.0-linux.i386.rpm

6. Go to the download page

   http://praya.sf.net/download.html

   and download the "Linux Architecture-Independent RPM."

7. Change into the directory containing the RPM. For instance, if you downloaded the RPM into /tmp, execute the following command:

   cd /tmp

8. Install the Praya RPM:

   rpm -Uvh praya-*.noarch.rpm

9. Exit the super-user shell:

   exit

10. Run the program:

    env PATH=/usr/java/jre1.3/bin:$PATH praya

1. Download and install a java runtime for your platform. Sun keeps a list of known java ports at

   http://java.sun.com/cgi-bin/java-ports.cgi

   You may want to start there.

2. Download the Any platform (.tar.gz file) or Any platform (.tar.bz2 file) from the download page.

   http://praya.sf.net/download.html

3. Open a terminal window
4. Change into the directory containing the RPM. For instance, if you downloaded the RPM into /tmp, execute the following command:

   cd /tmp

5. Unpack the archive:

   .tar.gz command:

   gzip -dc praya-*-java.tar.gz | tar xvf -

   .tar.bz2 command:

   bzip2 -dc praya-*-java.tar.bz2 | tar xvf -

6. Run the program:

   java -jar praya-*/praya.jar
