Configuring Net.Data for Use with Java Servlets

Servlets are Java classes that perform a role similar to that of CGI programs or Web server API plug-ins. Servlets run on a Java servlet-enabled Web server and extend the server's capabilities, much like the way Java applets run on a browser and extend the browser's capabilities. Use the following steps to configure your environment to invoke Net.Data through this Java servlet interface.

Unless you modified the directory structure or name when you created the HFS directory for Net.Data, the SMP/E install process installed the Net.Data DLLs and NetDataServlets.jar file in the directory /usr/lpp/netdata/servlet-lib. Because /usr/lpp/netdata is not your Web server's root directory, the Web server cannot handle client requests for Net.Data unless you make some additional modifications to the Web server's configuration.

To modify the Web server:

  1. Enable the Web server to run servlets. (See your Web server documentation for instructions on registering and using servlets.)
  2. Use either of the following approaches to complete the installation of the executable files and DLLs.
  3. Ensure that the permissions are 755 for the Net.Data executable files and DLLs and for each directory in the path to the executable files and DLLs.
  4. After configuring Net.Data, configure the IBM WebSphere Application Server to work properly with Net.Data servlets. Use one of the following methods:
  5. Restart the Web server.

Restriction: Do not specify more than one of the following directories in the LIBPATH statement of the Web server's environment variables file:
