Problem linking Postgresql JDBC driverb and Matlab (Linux) - Mailing list pgsql-jdbc

Hello,

I know this subject has also to do with Matlab, but I do not get any
answer on the Matlab forum, so I allow myself to crosspost my question
here. The Matlab error messages give however a lot of indications that
may be relevant to readers of this newsgroup.

I am still having some problems trying to connect Postgresql via the
JDBC driver and Matlab. I believe that Matlab does not know where the
driver is.

I am just wondering if I am using the right driver for my version of
Java and I am wondering whether my export CLASSPATH has the good
syntax. Can somebody help me as it is driving me nuts (I've been
working on this for a quite a few days) ?

I am also wondering why it requires the SSL module (cf below). It
seems that this function is supported by Java 1.4 only, and my Matlab
runs on Java 1.3.1. Shall I change the Java version of Matlab (and in
that case, how can I do it ?).

Thanks.

Configuration :
Slackware 9.1 - Matlab 6.5 R13 - Java 1.4.2_03, but Matlab runs on
1.3.1 Blackdown

EDU>> version -java

ans =

Java 1.3.1 with Blackdown Java-Linux Team Java HotSpot(TM) Server VM
    (mixed mode)

I tried drivers pg74.215.jdbc2ee.jar and pg74.215.jdbc3.jar

I added in classpath.txt :
/usr/local/pgsql/share/java/pg74.215.jdbc2ee.jar (and then tried with
pg74.215.jdbc3.jar)

and from bash :
export CLASSPATH=/usr/local/pgsql/share/java/pg74.215.jdbc2ee.jar:.

(is this the right syntax ?)

and from Matlab :

EDU>> java.lang.Class.forName('org.postgresql.Driver');

Thanks very much for your help.
