32 * The permission for which the <code>SecurityManager</code> will check
33 * when code that is running in an applet, or an application with a
34 * <code>SecurityManager</code> enabled, calls the
35 * <code>DriverManager.setLogWriter</code> method,
36 * <code>DriverManager.setLogStream</code> (deprecated) method,
37 * {@code SyncFactory.setJNDIContext} method,
38 * {@code SyncFactory.setLogger} method,
39 * {@code Connection.setNetworktimeout} method,
40 * or the <code>Connection.abort</code> method.
41 * If there is no <code>SQLPermission</code> object, these methods
42 * throw a <code>java.lang.SecurityException</code> as a runtime exception.
43 * <P>
44 * A <code>SQLPermission</code> object contains
45 * a name (also referred to as a "target name") but no actions
46 * list; there is either a named permission or there is not.
47 * The target name is the name of the permission (see below). The
48 * naming convention follows the hierarchical property naming convention.
49 * In addition, an asterisk
50 * may appear at the end of the name, following a ".", or by itself, to
51 * signify a wildcard match. For example: <code>loadLibrary.*</code>
52 * and <code>*</code> signify a wildcard match,
53 * while <code>*loadLibrary</code> and <code>a*b</code> do not.
54 * <P>
55 * The following table lists all the possible <code>SQLPermission</code> target names.
56 * The table gives a description of what the permission allows
57 * and a discussion of the risks of granting code the permission.
