Обсуждение: Regarding Error installing jdbc7.0-1.2.jar

hi,
I am using JDK1.2.2. I tried to install postgresql-7.0.3-2.i386.rpm and
its supporting rpms(devel,server,jdbc)
and I succeeded. I am able to open the database using 'psql' and create
tables. Then, I tried to install the jar
file for jdbc 'jdbc7.0-1.2. jar' and extracted it to the directory
/usr/lib/pgsql. Then, I tried to connect database
with jdbc with a sample java program. I gave it like the following way:

try
{
    Class.forName("postgresql.Driver");
    con=DriverManager.getConnection("jdbc:postgresql://IP
address/","user1","pass1");
}
catch(SQLException se){}
catch(ClassNotFoundException ce){}

.......
......
After compiling successfully, it comes with the following error:
Exception in the thread "main"
java.lang.NoClassDefFoundError : postgresql/Driver (wrong name:
org/postgresql/Driver)
at java.lang.ClassLoader.defineClass0(Native Method)
.......

What could be wrong?
Thanks in advance.

"Never extract the contents of these jar files!"

Put it in your CLASSPATH instead.

7.0 is pretty old by the way. You may want to get the latest
release of the driver from http://jdbc.fastcrypt.com/. But then
again, expect some problems when you use the latest release of
the driver against a 7.0 backend (7.1 is OK).

I'm not sure if you get this message via the list, but if you
post an a mailing list it would be nice if your address worked.
