WebWinds is a scientific visualization and analysis package, written as a Java application, which is designed to be an easy to use, multi-disciplinary tool. This version has both client and server capabilities.

This page addresses the following topics for users of platforms other than Unix, Linux, Macintosh and Windows:

Unix, Linux and Macintosh users should read their own page, and Windows users should read their own page.

Operating Environment

For all platforms, we recommend a processor speed of at least 200 MHz and at least 128 Mb of memory. With these minimum requirements you will be limited in the size of data sets that you can examine and the response times will be slow. The package requires about 25 Mb of disk space including documentation. WebWinds has been designed around the Java 1.2 or 1.3 API and may not run with version 1.1 of the Virtual Machine (VM).

In order to use the 3D displays, you must have OpenGL version 1.1 or later on your machine. In some cases, these installations must be done by someone with root privileges. In addition, you will need a compiled version of our C library containing Java wrappers to OpenGL.

Documentation

Documentation is built into WebWinds in the form of a context sensitive html help system. You can also browse the documentation using the online version.

Installation

OS/2

The installation requires acquisition of the Java Development Kit (JDK). WebWinds software, documentation and data are downloaded separately from the WebWinds page, after filling out the license agreement. The JDK is downloaded from IBM.

The installation process will produce scripts for either the client (wwclient) or server (wwserver), depending on which package has been downloaded. Here is a summary of the installation process:

Summary:

1. Delete any previous installed version of Java and WebWinds, keeping only text files which you have modified.
   
   
2. Download and install Java and WebWinds.
   
   
3. Configure Java and WebWinds for your environment.

Detailed instructions:

1. If you have previously installed WebWinds, or Java, it is wise (but not necessary) to delete the old files. This can be done by deleting the earlier JDK directories as well as the directories (and all directories contained in them) in your old WebWinds directory. Be sure to modify and save any text files that you altered in the WebWinds directory. Be sure to read the discussion of the datamanager.txt and config.sys files if you have an old version of WebWinds and would like to preserve its configuration. Other files that you may want to save and modify include paths.txt, dataobject.txt, overlays.txt and config.txt.
   
   
2. 1. If you already have the latest version of the JDK, skip to step b. Otherwise, install install version 1.3 of the JDK from IBM. Make a note of where you install the JDK directory. You can download the JDK documentation if you wish but it is not required.
      
      
   2. Create a directory (e.g. e:\webwinds on drive e: ) for the WebWinds application. In order for WebWinds to execute properly, the directory must be called 'WebWinds' (case insensitive). Download the file WWclient.jar or WWserver.jar file to this directory. Do the same for the data file, WWdat.jar. Next, you can run the following commands:

      		e:
      		cd \webwinds
      		d:\jdk1.3\bin\jar -xvf WWclient.jar (or WWserver.jar for the server)
      		d:\jdk1.3\bin\jar -xvf WWdat.jar

      This command list assumes that your WebWinds directory is on disk drive e: and is called webwinds. It also assumes that you have installed the JDK at d:\jdk1.3. Change these locations to fit your own situation.
      
      
3. 1. First you must let WebWinds know where to find things like your data files. See the discussion of the 'paths.txt' file.
      
      
   2. Create a script command file (wwclient.cmd) with the following in your webwinds (root) directory:

      	e:
      	cd \webwinds
      	PATH=d:\jdk1.3\bin;e:\webwinds\lib
      	SET JFILE=e:\webwinds\jar\pSlang.jar
      	java -cp %JFILE% -Djava.security.policy=java.policy -mx256m -jar %JFILE% ww.slang %1 %2
      

      If you would prefer to use the Java Runtime Environment (JRE) your command file would look the same except

      java -cp 

      would be replaced by

      	jre -cp
      

      Similarly, a server script command file (wwserver.cmd) would contain:

      	e:
      	cd \webwinds
      	PATH=d:\jdk1.3\bin;e:\webwinds\
      	SET JFILE=e:\webwinds\jar\pSlang.jar
      	java -cp %JFILE% -Djava.security.policy=java.policy -mx256m -jar %JFILE% wwserver.slang %1 %2
      

      Again, this command file assumes that your root webwinds directory is specified as e:\webwinds and that your root JDK directory is found at d:\jdk1.3. Change the file to reflect your situation.
      
      
   3. Finally, be sure to move any .txt files from earlier releases into your webwinds directory.
