Well some where in the java code for dspace there will be a call to
Class.forName(then the postgresql db driver class name).newInstance() .
That call should have failed if it were taking place and the class was
not found (unless it is wrapped in something like this try{ call class
for name } catch(Exception e) { then nothing here just swallow the error
}.
I know nothing about dspace, but I program java apps all the time. Have
you written to a mailing list for dspace before? I don't believe dspace
is included in the RH packages. Anyways, you need to make sure that the
postgresql.jar file is definitely where it should be. You should also
make sure that you have a build of dspace which is not broken. The best
place in my estimation would be the projects home and mailing lists.

Subject: Setting up DSPACE for Postgres access
I am currently testing a product by the name of dspace
(http://www.dspace.org) and require installing java since dspace is
completely java based. The problem is that during its installation it
needs to talk to pgsql via jdbc and I am getting the error: Exception
occurred:org.apache.commons.dbcp.DbcpException:
java.sql.SQLException: Driver not found for URL:
jdbc:postgresql://dspace.library.dal.ca:5432/dspace
org.apache.commons.dbcp.DbcpException: java.sql.SQLException: Driver not
found for URL: jdbc:postgresql://dspace.library.dal.ca:5432/dspace

I have tried the basic psql.class example provided by Postgres and get
the no class found error again. I cannot ofcourse go beyond this since
they have to talk to each other and if that doesnt happen nothing else
is going to work. In terms of the system and the env var's; here goes:
RH Linux 9 (kernel 2.4.20)
j2sdk1.4.2_01
dspace - 1.1.1
postgres - 7.3.4

I have never had any problems setting jdbc up before; but this time
around I cant see why this is happening. Is there something specific to
RH9 or am I missing something? I have tried to ask the PGSQL-General,
PGSQL-JDBC & DSPACE-Tech lists and they have no idea; am hoping
something comes up here that could solve this.
Any help would be greatly appreciated.
Thanks.
