Hi,
I am building a project where Java and MySQL are used together. It is a client-server project with F10 @ client side and CentOS5.2 @ server side. I use ConnectorJ as driver. There is a java.policy in place that allows a connect from anywhere on poerts above 1024, the line is:
Quote:
grant codeBase "file:/var/www/html/Tr/-"
{
permission java.net.SocketPermission "*:1024-65535","listen,connect,accept,resolve";
}
|
I have embedded the login data (login/password) into the code, using these to log in (locally and remotely via phpMyAdmin) is possible, and the grant to the required database has been set. However, when my module tries to log in, I get an access denied. The URL to connect to the database is:
Quote:
|
jdbc:mysql:192.168.1.75/Central1
|
Needless to mention the database Central1 @ 192.168.1.75 exists; has the appropriate user, with the appropriate grants...
The stackdump is as follows:
