From

Date:
Dear sir
   I'm interesting to use the PostgreSQL. In my
concept, I have 2 server in a RedHat 7.2. The one is a
webserver and the later is a dataserver. I read the
document of  PostgreSQL JDBC and practic it. It
doesn't work .
  The Fist method: In mye webserver, I install the
J2SDK1.4.0, the Tomcat-3.2.3.1noarch, a
PostgreSQL-7.1.3-2 and the PostgresSQL-JDBC-7.1.3-2.
By the way, I setup  Path and ClassPath in the
.bash_profile :
JAVA_HOME=/usr/java/j2sdk1.4.0
JDBC_HOME=/usr/share/pgsql/

PATH=$PATH:${JAVA_HOME}/bin
CLASSPATH=$CLASSPATH:${JAVA_HOME}/lib:${JDBC_HOME}/lib/jdbc7.1-1.2.jar
 and I write to a sample.java for test programe.When I
use javac to compile :
javac sample.java --- is complete and then I use java
to run this programe:
java sample ---- is message
Excepton caught.
java.loang.ClassNotFoundException:
org.postgresql.Driver
Please you  tell me about  this problem.

  The second method to make a postgresql.jar : In my
dataserve, I install  is a PostgreSQL server, Java and
Ant.  When I build  a drive. It can not  to mak a
postgresql.jar. Please you make this file to me and
tell me about  detail it.
 And I hope you to help me.  Sincerity

This message almost certainly means that the jdbc7.1-1.2.jar file is not in
the classpath when you execute the program. The other likely possibility is
that the driver name is mis-spelled. I'd suggest checking both of these
possibilities out very carefully. In particular, make sure that the
classpath doesn't get changed when the JVM is invoked. (I've seen this
happen with Debian Linux.)
