Hello,

I'm trying to connect to a postgresql database through the postgresql 
jdbc driver, but appears the errors below:

"$ java TesteJDBC_PGSQL
libgcj-java-placeholder.sh

This script is a placeholder for the /usr/bin/java
master link required by jpackage.org conventions.  libgcj's
rmiregistry, rmic and jar tools are now slave symlinks to these
masters, and are managed by the alternatives(8) system.

This change was necessary because the rmiregistry, rmic and jar tools
installed by previous versions of libgcj conflicted with symlinks
installed by jpackage.org JVM packages.

My login has permission to create databases and users and I have created 
a database called labprog3. I can use the command 'psql' with this 
database. I did set TCP/IP to true in 
/var/lib/pgsql/data/postgresql.conf, too.

I'm using the followed configuration:
kernel-2.6.10-1.766_FC3
kernel-utils-2.4-13.1.49_FC3
postgresql-7.4.7-3.FC3.1
postgresql-jdbc-7.4.7-3.FC3.1
postgresql-libs-7.4.7-3.FC3.1
postgresql-server-7.4.7-3.FC3.1
gcc-java-3.4.2-6.fc3

Does this problem due the libgcj, please?
Should I remove the gcc-java, please?

TIA,
Vinicius.

P.S.: Does this mailing list the best place to put this type of problem?
