I see now where my problem can be. If I extract the war file to
directory ${catalina.home}/psa-webapps/mydomain.com/myapplication/
and insert in the policy file
grant codeBase
file:${catalina.home}/psa-webapps/mydomain.com/myapplication/ {
permission java.net.SocketPermission localhost,resolve;
permission java.net.SocketPermission localhost:3306,connect,resolve;
};
I can then connect to the database, so I guess my problem is I'm not
using the proper syntax in the policy file for the .war
I will google for a while :-)

Hi everybody,
I have problems when connecting to mysql. I'm getting the following
exception when trying to connect to a mysql database:
(SQLException): java.sql.SQLException: Unable to connect to any hosts
due to exception: java.security.AccessControlException: access denied
(java.net.SocketPermission localhost resolve)
I have read about similar problems in google and tried to modify the
catalina.policy without success.
I deploy applications via a Plesk web interface which loads my .war
file, sets it in /var/tomcat4/psa-wars/mydomain.com/ creates a symlink
to the war file in /var/tomcat4/psa-webapps/mydomain.com/ and makes the
application available via mydomain.com/myapplication.
It works fine except when an application tries to access a mysql
database. I´m getting the exception above, even though I tried the
following lines in catalina.policy without success (found similar
exeptions to this one in google):
grant codeBase
file:${catalina.home}/psa-webapps/mydomain.com/myapplication/- {
permission java.net.SocketPermission localhost,resolve;
permission java.net.SocketPermission
localhost:3306,connect,resolve;
};
grant codeBase
file:${catalina.home}/psa-webapps/mydomain.com/myapplication/WEB-INF/lib/mysql-connector-java-3.0.9-stable-bin.jar
{
permission java.net.SocketPermission localhost,resolve;
permission java.net.SocketPermission
localhost:3306,connect,resolve;
};
I tried both of them one at a time and I restarted tomcat after every
modification made to the catalina.policy
I´m using tomcat 4.1.24 on a redhat linux Enterprise server, with
/mysql-connector-java-3.0.9 and jre 1.4.2.
Tomcat and mysql are in the same server.
The way I´m trying to access the database in a jsp is
conexion =
DriverManager.getConnection(jdbc:mysql://localhost/DATABASE?user=USERpassword=PASSWORD);
I've checked that the database exists, I can connect to the database
from a console as user USER with password PASSWORD.
The application works perfectly well in another server (debian woody
with tomcat 4.0) where it was not necessary to modify the security
policy.
I talked to a friend of mine who also knows something about tomcat and
told me that to access a database in the same server where tomcat is, it
should not be necessary to modify the catalina.policy file.
I have some experience with tomcat but i run out of ideas and things to
try. Any help to open my eyes would be appreciated.
Thanks a lot in advance,
Alfonso
