This one is easy.  Look for your postgresql.jar file, which is the JDBC Driver 
that is not being found.

Maybe you are not using the one from the rh-postgresql-java rpm, or have more 
than one in your CLASPATH, or it is in a different location than expected (I 
remember there was a change of location due to Linux Filesystem Standardization 
not long ago).

Assuming it is in /usr/share/java you can try the following:


export CLASSPATH=/usr/share/java/postgresql.jar

rhdb-explain rhdb-admin "Unable to find a java executable"

[James Beale]

Hi

I've nosed around the lists, and discovered what to do to get rhdb-cc
working OK, but I don't see where to resolve the rhdb-explain and rhdb-admin
"Unable to find a java executable" messages.

I don't have any .sh for rhdb-explain or rhdb-admin.  j2re-1.4.2_04-fcs is
installed, and I'm using RedHat 9.

Help would be most gratefully recived!

Thanks

James Beale

Hi James,

it is March break around here and the person who would know the answer 
in a snap is not here until Monday.  But let me try.

What exactly did you do to get rhdb-cc to run?  This can give me a hint 
on what you could do for the other two.

Regards,
Fernando
