| * |
| * The invokeAllMethods was setting only some specific properties Modified the code so that any key |
| * value mentioned in <property>tag is attempted for setting. If the property has a key as |
| * serverName , then the setter method is invoked with the name setServerName & the value present in |
| * value attribute is passed Made the Exception handling robust |
| * |
| * Changed invokeAllMethods wrt the change in cache.xml for vendor specific properties. |
