| <P> |
| This utility wrapper class is created to support AXIS2 runs |
| inside of Java 2 Security environment. Due to the access control |
| checking algorithm, for Java 2 Security to function properly, |
| <code>doPrivileged()</code> |
| is required in cases where there is application code on the stack frame |
| accessing the system resources (ie, read/write files, opening ports, and etc). |
| This class also improve performance no matther Security Manager is being enabled |
| or not. |
| <p/> |
| Note: This utility should be used properly, otherwise might introduce |
| security holes. |
| <p/> |
| Usage Example: |
| <code> |
| public void changePassword() { |
| ... |
| AccessController.doPrivileged(new PrivilegedAction() { |
| public Object run() { |
| f = Util.openPasswordFile(); |
| ... |
| <p/> |
| } |
| }); |
| ... |
| } |
