SecurityManager will check
* when code that is running an application with a
* SecurityManager enabled, calls the
* {@code DriverManager.deregisterDriver} method,
* DriverManager.setLogWriter method,
* DriverManager.setLogStream (deprecated) method,
* {@code SyncFactory.setJNDIContext} method,
* {@code SyncFactory.setLogger} method,
* {@code 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 | *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 {@code Connection} method * {@code abort} | *Permits an application to terminate a physical connection to a * database. | *
| setSyncFactory | *Allows the invocation of the {@code SyncFactory} methods * {@code setJNDIContext} and {@code setLogger} | *Permits an application to specify the JNDI context from which the * {@code SyncProvider} implementations can be retrieved from and the logging * object to be used by the {@code SyncProvider} implementation. | *
| setNetworkTimeout | *Allows the invocation of the {@code Connection} method * {@code 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 {@code DriverManager} * method {@code deregisterDriver} | *Permits an application to remove a JDBC driver from the list of * registered Drivers and release its resources. | *
