Subject tomcat.policy, SSL and SQL -> AccessControlException
Date Mon, 05 Feb 2001 08:05:10 GMT
hi all,

i have troubles configuring the tomcat.policy file.

my application reads some data from a mysql database running on port 3306, localhost.
i use the org.gjt.mm.mysql classes to connect to it and everything run fine.
i also use basic authentification with tomcat, the user data are also in the mysql database.

now i want make everything secure. i tried a lot and i got nearly everything working fine.
but i am not able to set the tomcat.policy, that the org.gjt.mm.mysql classes within my servlets
are allowed to connect to the mysql database.

tomcat.policy:
//java.  the org.gjt.mm.mysql jars are in jdk1.2.2/jre/lib/ext.
grant codeBase "file:d:/jdk1.2.2/lib/-"         {permission java.security.AllPermission;};
grant codeBase "file:d:/jdk1.2.2/jre/lib/-"     {permission java.security.AllPermission;};
grant codeBase "file:d:/jdk1.2.2/jre/lib/ext/-" {permission java.security.AllPermission;};

// Tomcat gets all permissions.
grant codeBase "file:d:/tomcat/lib/-"           {permission java.security.AllPermission;};
grant codeBase "file:d:/tomcat/classes/-"       {permission java.security.AllPermission;};

//my application directory
grant codeBase "file:d:/tomcat/webapps/shv_wb/WEB-INF/classes/-" {permission java.security.AllPermission;};
grant codeBase "file:d:/tomcat/webapps/shv_wb/WEB-INF/lib/-"     {permission java.security.AllPermission;};

it is realy confusing, because tomcat is able to read the authority-data for the basic authentification
out of the database, but my servlets are not allowed to do this.
i get this message from tomcat:
