| 56 | * <p>An object of this class implements the MBeanServer interface | ||
| 57 | * and, for each of its methods, calls an appropriate checking method | ||
| 58 | * and then forwards the request to a wrapped MBeanServer object. The | ||
| 59 | * checking method may throw a RuntimeException if the operation is | ||
| 60 | * not allowed; in this case the request is not forwarded to the | ||
| 61 | * wrapped object.</p> | ||
| 62 | * | ||
| 63 | * <p>A typical use of this class is to insert it between a connector server | ||
| 64 | * such as the RMI connector and the MBeanServer with which the connector | ||
| 65 | * is associated. Requests from the connector client can then be filtered | ||
| 66 | * and those operations that are not allowed, or not allowed in a particular | ||
| 67 | * context, can be rejected by throwing a <code>SecurityException</code> | ||
| 68 | * in the corresponding <code>check*</code> method.</p> | ||
| 69 | * | ||
| 70 | * <p>This is an abstract class, because in its implementation none of | ||
| 71 | * the checking methods does anything. To be useful, it must be | ||
| 72 | * subclassed and at least one of the checking methods overridden to | ||
| 73 | * do some checking. Some or all of the MBeanServer methods may also | ||
| 74 | * be overridden, for instance if the default checking behavior is | ||
| 75 | * inappropriate.</p> | ||
| 76 | * | ||
| 77 | * <p>If there is no SecurityManager, then the access controller will refuse | ||
| 78 | * to create an MBean that is a ClassLoader, which includes MLets, or to | ||
| 79 | * execute the method addURL on an MBean that is an MLet. This prevents | ||
| 80 | * people from opening security holes unintentionally. Otherwise, it | ||
| 81 | * would not be obvious that granting write access grants the ability to | ||
| 82 | * download and execute arbitrary code in the target MBean server. Advanced | ||
| 83 | * users who do want the ability to use MLets are presumably advanced enough | ||
| 84 | * to handle policy files and security managers.</p> | ||
