031 * The permission for which the <code>SecurityManager</code> will check
032 * when code that is running in an applet calls the
033 * <code>DriverManager.setLogWriter</code> method or the
034 * <code>DriverManager.setLogStream</code> (deprecated) method.
035 * If there is no <code>SQLPermission</code> object, these methods
036 * throw a <code>java.lang.SecurityException</code> as a runtime exception.
037 * <P>
038 * A <code>SQLPermission</code> object contains
039 * a name (also referred to as a "target name") but no actions
040 * list; there is either a named permission or there is not.
041 * The target name is the name of the permission (see below). The
042 * naming convention follows the hierarchical property naming convention.
043 * In addition, an asterisk
044 * may appear at the end of the name, following a ".", or by itself, to
045 * signify a wildcard match. For example: <code>loadLibrary.*</code>
046 * or <code>*</code> is valid,
047 * but <code>*loadLibrary</code> or <code>a*b</code> is not valid.
048 * <P>
049 * The following table lists all the possible <code>SQLPermission</code> target names.
050 * Currently, the only name allowed is <code>setLog</code>.
051 * The table gives a description of what the permission allows
052 * and a discussion of the risks of granting code the permission.
053 * <P>
