(See Figure 1) Figure 1: Cyberelay Architecture Portal ApplicationAggregation ServletThe only task for Aggregation Servlet is to accept portal page request sent from browser and to pass the received request to Request Process Chain for handling. Request Process ChainRequest Process Chain is composed of a set of nodes. Each node assumes a certain task. While the received request traverses a node, a certain task would be accomplished. The outcome of a successful traversal would be a generated portal page. (See Figure 2) Figure 2: Portal Request Process Chain Request Pre-process Node Its responsiblities includes: Wrapping the incoming portal request/response to enrich them with additional built-in request attributes; Parsing/validating the incoming request URL; Logging out portal application if the incoming request is a logout request; Resolving requesting page. If not such page found, a PageNotFoundException would be thrown; Any other task need to be done during request pre-processing phase; Figure 3: Page Aggregation Framework The project is still under extensive development.
