Dynamic Multi-sourced Persisted Enterprise Java Bean (EJB) instances are dynamically created on a J2EE compliant Application Server to access data contained in multiple data source systems. This Dynamic Multi-sourced Persisted EJB is a general class responsible for dynamically aggregating source system information and securing it based on a Context definition. Individual EJB attributes that include mapping, caching and security definitions are mapped to individual pieces of data in source systems by the Context definition. A Context definition can be reloaded during execution as desired. Applications can access the Dynamic Multi-sourced Persisted EJB directly, or use a Session EJB to create a static interface to the dynamically mapped, cached and secured data. Using an attribute securing element, a security engine enforces access requirements on a system-wide basis.

Provided is a multicast distribution system which can perform a multicast distribution by selecting a communication path satisfying a communication feature required by a multicast group. A distribution source router (Rs) performs a multicast distribution to routers (R1 to R5) constituting a multicast group based on an application via a mesh virtual network connected to a plurality of routers. When the CPU load ratio and the multicast group communication feature exceed threshold values, the distribution source router updates the number of branches and the depth of the multicast tree which distributes a packet from the router and starts is reconfiguration of the multicast tree. When reconfiguring the multicast tree, the distribution source router references a path feature of the mesh virtual network, selects a communication path having a sufficient path feature with a higher priority, and generates a routing table based on the multicast tree.

Thus, the invention can realize balanced SSL VPN gateway loads in a simple and reliable way at low cost.

Dynamic Multi-sourced Persisted Enterprise Java Bean (EJB) instances are dynamically created on aJ2EE compliant Application Server to access data contained in multiple data source systems. This Dynamic Multi-sourced Persisted EJB is a general class responsible for dynamically aggregating source system information and caching it based on a Context definition. Individual EJB attributes that include mapping, caching and security definitions are mapped to individual pieces of data in source systems by the Context definition. A caching definition can be reloaded during execution as desired. Applications can access the Dynamic Multi-sourced Persisted EJB directly, or use a Session EJB to create a static interface to the dynamically mapped, cached and secured data. Bi-directional synchronization of the cache between client and source system data and modifications of data attributes are achieved without recoding, recompiling and redeploying of custom coded solutions.

A mount system for an auxiliary component includes two side brackets and a top bracket for rigidly attaching an auxiliary component to an engine casing. Each side bracket defines mount segments, a deformable member and two retainer members between the mount segment. The deformable member plastically deforms during a fan-blade out event, thereby absorbing a majority of the high shock load experienced on the auxiliary component. The retainer members maintain the attachment between the auxiliary component and the engine casing subsequent to the fan-blade out event.
