UTGB Request Dispatcher Mechanism

web.xml setting

Add the following description into you web.xml.

• The lines param-name=base-package, param-value=(application base) specifies the location (base package name) where the RequestDispatcher searches recursively for RequestHandler? implementations.
• With the following setting, an HTTP request, e.g., ​http://localhost:8989/hello.action, is mapped to the request handler org.utgenome.gwt.utgb.server.app.Hello class. The upper letters are converted into the lower letters when mapping the request, e.g., Hello action can be accecced via hello.action URL.
  • Another example using hierarchies of actions: ​http://localhost:8989/admin/login.action is mapped to org.utgenome.gwt.utgb.server.Login class.
