Thread: 7.0 - 7.2 upgrade, org.postgresql.Driver Class not found
I am trying to upgrade a working application from Postgres 7.0 to 7.2. I have downloaded the pgjdbc2.jar and installed it next to the old jar. When I try to run with the new jar, I get a class not found exception: org.postgresql.Driver, when I switch the path back to the old driver I don't have this problem (but do have others due to the mismatch between the jdbc jar version, and thet Postgres version.) I have tried to look into the jar with three different jar/zip viewers, none of which seem to think pgjdbc2.jar is in a valid zip/jar format. The viewers are not the latest, but they have all looked inside other jars in the past. I have downloaded the jar twice and they compare ok. I get the same Class not found with the older /pg72/jdbc7.1-1.2.jar as well. The jdbc7.1-1.2.jar is the one that works. (For the Class not found part) I am running RH Linux 7.2, Apache 1.3.14 ApacheJServ/1.1.2/ GNUJSP 1.0 wrapper (yes I know, long in the tooth, but they were to be upgraded after the Postgres upgrade.) We are using the IBM JVM 2-13 which I believe is a Java 1.3 VM (I'm not sure if the JIT compiler is enabled) Any thoughts would be most welcome. Harrison huhl@email-services.net
If the jar is invalid, then it simply isn't going to work. How are you downloading the jar?

Harrison,
Ok, can you try loading the driver with some little main
ie
public class someClass
{
public static void main( String [] args ) throws Exception
{
class.forName("org.postgresql.Driver");
}
}
just to see if it works
Then we can narrow down what's up with jserv

Dave:
Thanks for your support.
I've rolled back to our Postgres 7.0 server, and after several mistaken attempts
at selecting the appropriate old driver have the application back up.
What is interesting is that various of the old drivers also produced the same
Class not found that I'm having with the upgrade.
Is it possible that when the driver attempts to load and finds that something
doesn't match that the load fails and you get the class not found message?
I know with the IBM JVM I'm using, I get compile time Class not Found errors when
the class exists, but one of the classes it requires is not found.
The following code loads the specific database jdbc driver(s). Here
org.postgres.Driver
(The input string is pulled from an LDAP directory, and is tokenized so that
databases like IBM's DB2, which at least in an older version, wants to load two
separate classes.)
public void loadDrivers(String s) throws Exception
{ StringTokenizer st= new StringTokenizer(s);
while (st.hasMoreTokens()) { Class.forName(st.nextToken()); }
}
As mentioned above, once I got the proper older driver respecified, the older
Postgres came up.
The older driver I am currently using is pg71/jdbc7.1-1.2.jar, and this is going
to Postgres 7.0 on a separate machine.
The following comes from jdbc meta data queries for the above older configuration.
product: PostgreSQL
ver: 7.0.3
driver: 7.1
driver name: PostgreSQL Native Driver
below are the configuration line from jserv.properties that specify where to look
for the relevant driver, following that is a directory listing of the jars in
question
(they are being viewed over a Samba share, thus are in DOS, not Linux format)

I double checked the file permissions, and both pgjdbc2.jar and pg71/jdbc7.1-1.2
(now) have the same: -rwxr-xr-x, and both files are owned by the same owner. and
their directories also have matching (dir to dir) permissions and both dir's have
the same owner.
When I went back to see if the permissions were the same, they were not, so I
changed them and double checked. (No luck.)
When I was rolling back to the working older set, I inadvertently pointed the
7.1-1.2 drive at the 7.2.2 db, and got the same Class not found error.
I'm strongly thinking that the actual error message is not at all indicative of
what is going on.
(However when I try to reproduce the old driver, new db, I can't reproduce that
error, so it seems something is caching something.)
Following is the stack trace of the attempt to load pgjdbc2.jar

The following is from snoop.jsp: Server Info: ApacheJServ/1.1.2/ GNUJSP 1.0
wrapper
Snoop also reminded me that we are using an older compiler for our classes, and my
partner reminded me that we'd had issues running GNUJSP with our classes when we
ran the new compiler. Since this error seems to come from well down in the system
libraries, I doubt that its had any contact with our byte code, so I don't think
this likely to be a factor.
I'm also remembering a problem I had years ago with trying to get an application
to run on Visual Cafe's JVM. The jdbc driver seemed to load and test fine but the
application would Watson (NT), after much frustration, when I used the Sun JVM the
problem vanished.
Is anyone else successfully running pgjdbc2.jar with the IBMJava2-13 JVM?
Still stumped, but thanks for the support...
Harrison

the 7.2.2 database and try a getColumns()

I used NS 4.7 to down load the following: http://jdbc.postgresql.org/download/pgjdbc2.jar And compared it to the one installed by the Postgres 7.2.2 RPM They match Harrison Dave Cramer wrote: > If the jar is invalid, then it simply isn't going to work.
