Frank Berke's how-to
article in
the July, 2001 OS/2 VOICE newsletter describes LimeWire, a Java-based client
for the Gnutella network. Frank does an excellent job describing this useful client
and the genesis of the Gnutella network, essentially a successor to the Napster
phenomenon for peer-to-peer file sharing.
There are some minor complexities running LimeWire on OS/2 Warp and eComStation
systems, and this Part 2 article explains the details. These techniques may also
give you a better understanding of the Java environment on these platforms and how
to get other "100% pure" Java applications up-and-running on your PC.
NOTE: Please respect the copyrights of authors, artists, and their publishers.
Use the Gnutella network only for legitimate file sharing.
Downloading the Software
LimeWire is compatible with both the free IBM-supplied Java 1.1.8 runtime as
well as the subscription-only Java 2 (Version 1.3) runtime. You can get the Java
2 runtime as part of eComStation, the OS/2 Warp Convenience Pak, or with an IBM
Software Choice subscription.
Assuming you'd like to run LimeWire with Java 1.1.8, you should download the
following software packages:
The IBM Java 1.1.8 Runtime with Unicode can be obtained from the IBM
Software Choice web site. IBM's Java Development Centre in Hursley has a download
site for RUNTIME.EXE,
the latest fix package for the Java 1.1.8 runtime.
Although IBM supplies an optional Java Foundation Classes (JFC)/Swing runtime
for OS/2 Warp JDK 1.1.8, LimeWire seems to run much better with the slightly more
up-to-date Swing implementation from Sun. Obtain Sun's swingall.jar file
from the JFC/Swing
1.1.1 Zip package.
Installation of the Java Environment
Install the Java 1.1.8 Runtime with Unicode per IBM's instructions. (Note that
you'll need the IBM Feature Installer and Netscape browser to complete the installation.)
Reboot after installation. Without starting Netscape, or any other application which
uses Java, unzip the RUNTIME.EXE file to the drive where you installed
Java. Allow RUNTIME.EXE to overwrite the old files.
To verify that the Java 1.1.8 runtime is installed and updated correctly, open
an OS/2 Window and type the following at the command line:
java -fullversion
You should see something on your screen that looks like this line:
JAVA.EXE full version "JDK 1.1.8 IBM build o118-20010830 (JIT enabled:
javax V3.5-IBMJDK1.1-20010830)"
Make sure the date code (20010830, or August 30, 2001) is the same or newer.
Otherwise you may not have installed the Java fix correctly.
LimeWire Installation
Create a directory for LimeWire (such as C:\Apps\LimeWire), and unzip
the LimeWireWinNoVM.zip file into this directory. Also, unzip the swingall.jar
file to the same directory.
To start LimeWire from a desktop program object, drag a Program template from
the Templates folder to your desktop. A tabbed notebook should pop up, with the
Program tab selected. Fill in the following values:
|
Path and file name |
C:\JAVA11\BIN\JAVAPM.EXE |
|
Parameters |
-classpath .;LimeWire.jar;collections.jar;swingall.jar;C:\Java11\Lib\classes.zip com.limegroup.gnutella.gui.Main |
|
Working directory |
C:\Apps\LimeWire |
If you did not install Java 1.1.8 and/or LimeWire to Drive C, change the drive
letters above as needed.
Click on the Icon tab, then fill in the name you'd like to assign to the program
object (such as LimeWire). Finally, close the notebook to save these settings. Double
click on this new program object to start LimeWire. (See Part
1 for information on how to use LimeWire.)
