Installation Instructions

2 Mar 1997
  1. NetCharts is distributed as either a compressed TAR file or as a ZIP file. Depending on the distribution type you received, use the following commands to unpack the files:

    Compressed TAR File: (Unix)

    1. Create a directory to hold the distribution. We suggest that it be located OUTSIDE of your Web hierarchy in order to prevent outsiders from accessing the distribution. For example,
      	mkdir /usr/local/NetCharts
      
    2. Move the NetCharts.tar.Z file to the newly created directory:
      	mv NetCharts.tar.Z /usr/local/NetCharts
      
    3. Uncompress the TAR file:
      	uncompress NetCharts.tar.Z
      
    4. Extract the files and subdirectories
      	tar xvf NetCharts.tar
      

    ZIP File: (Windows/Unix)
    NOTE: You need to use a version of UNZIP that preserves full length filenames in Windows 95 or NT. Otherwise, the truncated file names will not be found by the Java class loader.
    1. Create a directory to hold the distribution. We suggest that it be located OUTSIDE of your Web directory in order to prevent outsiders from accessing the distribution. For example,
      	File --> New Folder --> c:\NetCharts
      
    2. Move the NetCharts.zip file to the newly created directory

    3. Unzip the ZIP file using your favorite ZIP utility.


  2. Once the files and directories have been unpacked, you need only create a link to the classes subdirectory from somewhere in your Web hierarchy or copy the contents of the classes directory to one or more directories within your Web hierarchy.

    We strongly recommend that you create a /NetCharts directory at the top of your Web hierarchy and place the classes there (or make a link to the classes subdirectory). In that way, any HTML file in the Web hierarchy can easily use the applets using the following applet tag:

    <applet codebase=/NetCharts code=NFPiechartApp.class>
    
    Otherwise, the class files will have to be referenced relative to each HTML file, which will be difficult to maintain over time.

  3. You may also want to install the class directory in a location that is accessible to your browser via the CLASSPATH variable. This reduces the time needed to download the classes over a network, because they will be automatically loaded from the local disk drive by the browser. See your browser instructions for the exact method needed to install class files on the client machine.

  4. If you haven't already registered your copy, you need to contact the NetFactory to get a valid license file entry for your server. You will need to provide us with the IP address for each server being licensed. At that time, you will be provided with a set of license file entries via email, fax or phone, depending on your choice.

    The license file entries can be added to your license file, NFLicense.dat, which should be stored in the classes subdirectory.

    The file can be edited using any standard text editor. Additional licenses can be added at any time, simply by appending that file. In that way, a single file can be used to enable NetCharts objects on multiple servers within an organization.

  5. BOOKMARKS: You may want to add doc/index.html and examples/index.html to your browser bookmarks in order to quickly access the documentation and examples.
