It does not need to conform to for example an underlying Java Domain Model that is being used to define your “Server Application”. A Service Layer is used to “Serve” “Client Applications”. A “Client Application” needs another perspective of the world than your “Server Application” because it has a different purpose. The purpose of a “Client Application” is to “Serve” a “User”. Serving a “User… text/html 2012-05-04T15:01:40+02:00 Arjen Schoneveld http://www.navajo.nl/doku.php/book:tiplets?rev=1336136500&do=diff1336136500 Table Of Contents Enter your E-Colleague In a true computing eco-system, a human user interacts and cooperates with software colleagues. A software colleague, represented by a (composed) service, can pro-actively assist a user in his/her work as opposed to relying on a classi- cal information pull by this user. Reaching a user can be achieved by actively starting a conversation from a software component, orchestrated by a software workflow, to his human colleague. In technical terms, by pushi… text/html 2012-05-04T15:00:01+02:00 Arjen Schoneveld http://www.navajo.nl/doku.php/book:tipiworldview?rev=1336136401&do=diff1336136401 About Tipi Table Of Contents Tipi is used to give Navajo Services a good looking ‘face’. A Tipi applications only ‘knows’ two types of interaction: user interaction and service interaction. We all know what user interaction means: letting a human user interact with a computer application using a e.g. a typical configuration that consists of a screen, a keyboard and a pointing device. In order to accomplish meaningful tasks for its human user a Tipi application must be able to interact… text/html 2012-05-04T14:59:09+02:00 Arjen Schoneveld http://www.navajo.nl/doku.php/book:start?rev=1336136349&do=diff1336136349 Table of Contents * Introduction * Part I: Service Oriented Programming * Part II: Navajo * Navajo Document: a Service Oriented Domain Language * Navajo Script: processing and composing Services * The Java Connection: Functions, Adapters and POJOs * Recognizing typical SQUID patterns in Enterprise Applications * Using other languages for developing Navajo Services * Using iBatis as an Object Relational Tool * Using the Eclipse Plugin for Developing Scripts * Contro… text/html 2012-05-04T14:57:42+02:00 Arjen Schoneveld http://www.navajo.nl/doku.php/book:workflows?rev=1336136262&do=diff1336136262 Table Of Contents A Navajo Service workflow is defined using states and state transitions. An event in combination with a conditional expression can trigger a state transition. A trigger is defined by an event and (optionally) a condition, whenever the event occurs and the condition is valid, the trigger fires and a new workflow state will be entered. Within a workflow state, new transitions can be defined declaratively and specific state-dependent services can be invoked; that can trigger anot…
