You mentioned that you thought it was "</font>just a case of making
sure the JVM could load libodbc.so" Is there anything that must be done
to allow a JVM to access a library such as this? I just assumed that
having the library in a well known place (/usr/lib) and having it world
readable/executable is enough. I am not very familiar with java, are
you aware of anything like an env variable that must be set?<br>

I am attempting to use SUN's JDBC-ODBC bridge to connect to an odbc
data source (CentOS 5.2 and most recent unixODBC). The odbc data source
works fine using isql, the DataManager, and OpenOffice Base. When I
attempt to access the odbc data source through the jdbc bridge I get a
java error that makes me think the jdbc bridge is not "finding" the
unixODBC odbc libraries (a null pointer exception during the
initialization call). I have both unixODBC and the odbc data source
logging, and neither creates their log files. So, I do not believe they
are getting called. Using OpenOffice Base, I was able to test and
verify that the jdbc bridge driver is being loaded.
<br>
<br>
Does anyone have any experience using this bridge with unixODBC? Is
there any special configuration that is needed (such as passing the
odbc driver library path as a connection argument) to link the jdbc
bridge with the unixODBC odbc libs? I realize that sun's jdbc bridge is
very sub-par, but unfortunately I am stuck with it for a demo project
(for now at least).

Andy help would be greatly appreciated,

Whats the actual error you are getting?

<br>
Last tine I checked it was just a case of making sure the JVM could
load libodbc.so
