| Sub-component of [OpenEJB](design.html) |
| |
| <a name="Design-Assembler-Definition"></a> |
| ## Definition |
| |
| Instantiates and assembles a configured, runnable, instance of the |
| container system and all sub-components. Vendors needing extreme control |
| over the construction of the container system can get it by implementing |
| this class. Doing this comes with large amounts of resposibility and |
| complexity and should not be done without a deep understanding of OpenEJB. |
