Java Database Connection Problem Environment: The hope.class, java application is working under the Visual Café (Data Base Edition 3.0c) environment using jdbc6_5-1_1.jar (loaded in the Internal VM in the Environmental Options, as a classpath setting). The PostgreSQL database (Version 6.5.2) is running on the Sun Sparc demo.ppc.pims.org. The web server is running Netscape Suitespot 3.5.1 on another Sparc. Our users will access the web server using Netscape Communicator 4.5 or higher from a PC running Windows NT 4.0 Service Pack 4 or 5. Suitespot Administrator Setup An additional Directory is made with the Suitespot Administrator as follows: ADDITIONAL DOCUMENT DIRECTORY Prefix /hope Directory /vol1/HTML/pass The Suitespot Administrator configuration is: Primary: Directory /vol1/HTML Index Filenames: index.html,home.html,index.htm The following is in the script for starting the Suitespot server, the https-default start script: CLASSPATH=$CLASSPATH:/export/home/huffmana/postgresql.jar:/export/home/huffmana: /vol1/HTML/pass:/vol1/HTML/pass/postgresql.jar Ive also set the CLASSPATH in the UNIX shell before starting nohup postmaster i HTML <HTML> <HEAD> <TITLE>hope.html</TITLE> </HEAD> <BODY> <APPLET CODE="hope.class" archive="postgresql.jar"WIDTH=665 HEIGHT=631></APPLET> </BODY> </HTML> Running from Netscape Communicator Netscape Communications Corporation -- Java 1.1.5 Type '?' for options.
