Обсуждение: postgresql JDBC error
Hi everyone, this is my first mail to this mailing list. I was wondering if anyone encountered this error when trying to establish a JDBC connection to a postgresql database? "SQLException caught: Something unusual has occured to cause the driver to fail. Please report this exception: java.security.AccessControlException: access denied (java.net.SocketPermission localhost resolve)" is it a corrupt database? by the way the server is running redhat 6.x, apache and tomcat 3.x Thanks in advance Lloyd Holman
Hi Lloyd- It sounds like maybe you need to add a line to your pg_hba.conf file to authorize the connection. (Remember that if you are running Tomcat, the user that Tomcat connects as may be different from the user you develop as...) The low-security-but-make-it-work approach would be to add this line: host all 127.0.0.1 255.0.0.0 trust This assumes you are on the same machine.

Lloyd, No it's not a corrupt database, looks like you are trying to run an applet? The error is related to your jvm not being able to open a socket. Nothing to do with the database yet Dave -----Original Message----- From: pgsql-jdbc-owner@postgresql.org [mailto:pgsql-jdbc-owner@postgresql.org] On Behalf Of Lloyd Holman Sent: Wednesday, January 09, 2002 11:33 AM To: pgsql-jdbc@postgresql.org Subject: [JDBC] postgresql JDBC error Hi everyone, this is my first mail to this mailing list.

Additionally, you may need to start postgres with "-i".
