Editing BPM (section)

===JPDL===
jPDL defined by JBoss and part of [[#JBoss_jBPM| JBoss BPM]] is an extensible XML-based process definition language, and is suitable for a range of problems, from defining web application page flow, to traditional workflow management, all the way up to orchestration of services in a SOA environment.

The '''jPDL suite''' is a download that contains all the jBPM components bundled in one easy download. The suite mainly contains:
* the '''jBPM core library''': The core workflow and BPM functionality is packaged as a simple java library. This library includes a service to manage and execute processes in the jPDL database. 
* the '''jPDL process designer''': a eclipse plug-in
* '''jBPM console web application'''
* '''jBPM identity component'''
* '''jBPM Job Executor'''

The configuration has the form like the following example:

 <pageflow-definition name="numberGuess">
   <start-page name="displayGuess" view-id="/numberGuess.jsp">
      <redirect/>
      <transition name="guess" to="evaluateGuess">
        <action expression="#{numberGuess.guess}" />
      </transition>
   </start-page>
   <decision name="evaluateGuess" expression="#{numberGuess.correctGuess}">
      <transition name="true" to="win"/>
      <transition name="false" to="evaluateRemainingGuesses"/>
   </decision>
   <decision name="evaluateRemainingGuesses" expression="#{numberGuess.lastGuess}">
      <transition name="true" to="lose"/>
      <transition name="false" to="displayGuess"/>
   </decision>
   <page name="win" view-id="/win.jsp">
      <redirect/>
      <end-conversation />
   </page>
   <page name="lose" view-id="/lose.jsp">
      <redirect/>
      <end-conversation />
   </page>
 </pageflow-definition>
