Leon,
Have you granted access to the directory, like this?
grant codeBase "file:${catalina.home}/webapps/-" {
permission java.net.SocketPermission "192.168.12.81:3306",
"connect";
};
Although this way of working with mysql/logs is a bit strange... you
have logging at your disposal in most java servers by default, and
most connections to JDBC can be configured from a standard *-sql.xml
file that all of them understand (most parts, anyway).
Why not stick to the specs and what's available on the market?
Regards,
Alex D.
