Dear Members,
I'm currently involved in a database project and have written a GUI in
Java to manipulate a PostgreSQL database (server version 8.2). I've
developed the GUI using NetBeans 5.5 (loaded the
postgresql-8.2-504.jdbc3.jar as JDBC driver) on a Windows XP
professional platform. Building the projetc's jar file works fine and
running the Java program on the Windows XP machine runs smoothly.
Deleting, adding and updating tuples works just fine!
Now I want to run the program's jar file on a Linux platform (OpenSuSe
10.2). So I launch the application with the command: java -jar
AppName.jar at the command prompt, and the program starts correctly, by
displaying the GUI. However when I want to try to connect to the
database by entering the required username and password, I get the
ClassNotFoundException: org.postgresql.Driver runtime error. By the
way, the server on the Windows XP machine is listening for TCP/IP
connections (listen_addresses = '*' in the postgresql.conf file!)
Can anybody give a hint on how to solve this problem? Some CLASSPATH
problem perhaps? Specifying the JDBC driver in the classpath option of
the java-command doesn't seem solve the problem either. I'm afraid that
I don't understand the loading mechanism of the JDBC driver, and perhaps
someone can explain it to me. Thanks in advance!
Regards,
Gerard Verhaag
