Hi, I'm checking PostgreSQL JDBC Driver. I've downloaded RPM for PostgreSQL JDBC Driver from Yum Repository. http://yum.postgresql.org/8.3/redhat/rhel-5-x86_64/repoview/postgresql-jdbc.html And I checked the contents. It seems some drivers(for jdbc2, jdbc2ee, jdbc3), but it is just same symbolic link to postgresql-jdbc-8.3.607.jar. # ls -l postgresql* postgresql-jdbc-8.3.607.jar postgresql-jdbc.jar -> postgresql-jdbc-8.3.607.jar postgresql-jdbc2.jar -> postgresql-jdbc.jar postgresql-jdbc2ee.jar -> postgresql-jdbc.jar postgresql-jdbc3.jar -> postgresql-jdbc.jar I think I should change jar file corresponding JDK/JVM version. http://jdbc.postgresql.org/download.html#others Also, newer version(9.1-901) has one jar but I don't know which version of JDK/JVM is corresponding. # ls -l postgres* postgresql91-jdbc-9.1.901.jar postgresql91-jdbc.jar -> postgresql91-jdbc-9.1.901.jar Which JDK/JVM version is corresponding ? regards, -------------- NTT Software Corporation Tomonari Katsumata -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
