                                               throws java.lang.Exception

Override the execute method in LookupDispatchAction to parse URLs and forward to methods without parameters. If the action mapping parameter is present it will be used. If not, it will check if the action path contains any of the values from the Map returned by getKeyMethodMap() and will forward to the method called after that value. If more that one match the result is not specified. Also will forward to unspecified method when no parameter is present. For example if the values from getKeyMethodMap() are edit=edit update=update view=view create=create other=another The following map between paths and methods will be used

• edit*.do -> edit method
• update*.do -> update method
• view*.do -> view method
• create*.do -> create method
• find*.do -> find method
• other*.do -> another method

Parameters:

mapping - The ActionMapping used to select this instance

request - The HTTP request we are processing

response - The HTTP response we are creating

form - The optional ActionForm bean for this request (if any)

Returns:

Describes where and how control should be forwarded.

Throws:

java.lang.Exception - if an error occurs
