| This module implements the configuration editors that support editing "Sun specific" |
| deployment descriptors. These editors are based on an extended version of the |
| API's defined in JSR-88, that is customizer based. |
| </p> |
| <p> |
| It was developed by refactoring the server integration module and jars that |
| supported SJSAS 8.1 PE in NetBeans 5.0. The goal of the refactoring is to allow |
| multiple integration modules (for various Sun projects) to re-use these editors. |

| <p> |
| The module depends on the implementation of a few standards from the Application Server itself. The plugin dynamically loads JAR files from the app |

| or politely ignore settings stored by a future version? |

| <hint> |
| Very helpful for reading settings is to store version number |
| there, so future versions can decide whether how to read/convert |

| --> |
| <answer id="compat-version"> |
| <p> |
| There is an earlier version of the plugin that shipped with NetBeans 3.6 in auto update center. These settings are not compatible with the new plugin, but |

| We expect future versions of the plugin to understand the current structure of the settings going forward. |

| <p> |
| The plugin depends a lot on the Application Server 8.1 product and needs an installation of it to be fully functional. We need for example the |

| We do call a lot foreign APIS implemented by the Application Server. For the JSR 88 ones, we need to interject a Thread Context Class loader before any 88 calls. |
| because of some limitations of the App Server implementation for the JMX remote library usage, which did not specify a class loader to find a factory for the JMX remote implementation. |
