The permission for which the SecurityManager
will check
when code that is running an application with a
SecurityManager
enabled, calls the DriverManager.deregisterDriver
method, DriverManager.setLogWriter
method,
DriverManager.setLogStream
(deprecated) method, SyncFactory.setJNDIContext
method, SyncFactory.setLogger
method, Connection.setNetworkTimeout
method, or the Connection.abort
method.
If there is no SQLPermission
object, these methods
throw a java.lang.SecurityException
as a runtime exception.
A SQLPermission
object contains
a name (also referred to as a "target name") but no actions
list; there is either a named permission or there is not.
The target name is the name of the permission (see below). The
naming convention follows the hierarchical property naming convention.
In addition, an asterisk
may appear at the end of the name, following a ".", or by itself, to
signify a wildcard match. For example: loadLibrary.*
and *
signify a wildcard match,
while *loadLibrary
and a*b
do not.
The following table lists all the possible SQLPermission
target names.
The table gives a description of what the permission allows
and a discussion of the risks of granting code the permission.
permission target name, what the permission allows, and associated risks
Permission Target Name
What the Permission Allows
Risks of Allowing this Permission
setLog
Setting of the logging stream
This is a dangerous permission to grant.
The contents of the log may contain usernames and passwords,
SQL statements, and SQL data.
callAbort
Allows the invocation of the Connection
method abort
Permits an application to terminate a physical connection to a
database.
setSyncFactory
Allows the invocation of the SyncFactory
methods setJNDIContext
and setLogger
Permits an application to specify the JNDI context from which the SyncProvider
implementations can be retrieved from and the logging object to be used by the SyncProvider
implementation.
setNetworkTimeout
Allows the invocation of the Connection
method setNetworkTimeout
Permits an application to specify the maximum period a
Connection
or
objects created from the Connection
will wait for the database to reply to any one request.
deregisterDriver
Allows the invocation of the DriverManager
method deregisterDriver
Permits an application to remove a JDBC driver from the list of
registered Drivers and release its resources.
