BPEL实例运行[1]——改写源码

本文介绍了如何把Oracle的一个BPEL实例改写后部署到ActiveBpel上，并运行该实例。欢迎大家对其中的错误给予指正~

该实例的业务逻辑详见http://searchwebservices.techtarget.com.cn/tips/4/2551504.shtml，此教程详细描述了实例所涉及到的3个wsdl文件以及4个bpel文件，并介绍如何部署到Oracle的BPEL服务器。实例的运行需要用到Oracle BPEL Process Manager ，它提供了一个 BPEL 控制台，通过它可以在 BPEL 服务器域中执行、监视、管理和调试 BPEL 流程。

实例简介：

定义雇员出差安排的简化业务流程:客户端调用此业务流程，指定雇员姓名、目的地、出发日期以及返回日期。此 BPEL 业务流程首先检查雇员出差状态。假设存在一个可用于进行此类检查的 Web 服务。然后，此 BPEL 流程将检查以下两家航空公司的机票价格:美国航空公司和达美航空公司。再次假设这两家航空公司均提供了可用于进行此类检查的 Web 服务。最后，此 BPEL 流程将选择较低的价格并将出差计划返回给客户端。

Oracle版的实例源码可以下到，为了使它可以运行到ActiveBpel之下，首先要改变其文件目录结构。

在ActiveBPEL Designer（V3.0）下新建一个工程，命名为AirLine

新建四个文件夹，分别命名为bpel,META-INF,pdd,wsdl.

在bpel文件夹下新建5个BPEL流程文件，这5个中，client.bpel是Oracle的实例中原来没有的，其他4个原先都有。现把它们的代码粘贴如下：

       Client.bpel，该流程用于调用Travel.bpel流程，接收Travel.bpel的回调，并将结果返回。

在这个流程的<partnerLines>的部分定义了两个partnerLink，一个是用于接收客户端调用的”client”，这是一个同步调用，因此只指定一个角色，另一个是用于调用Travel.bpel流程和接收回调的”travel”，这个调用是异步的，因此指定两个角色。

    < bpel:partnerLinks >
        < bpel:partnerLink  myRole ="travelService"  name ="client"  partnerLinkType ="cli:clientLT" />
        < bpel:partnerLink  myRole ="travelServiceCustomer"  name ="travel"  partnerLinkType ="trv:travelLT"  partnerRole ="travelService" />
     </ bpel:partnerLinks >

 

在 <variables> 标签中定义了两个变量，用于接收数据和返回数据，其 messageType 分别为 trv:TravelRequestMessage 和 aln:TravelResponseMessage 。

这个流程在活动定义的部分没有使用 sequence 标签而使用了 flow 标签，因而为了让一个活动在结束以后可以跳转到下一个活动，在开始的部分定义了 3 个链接 (link) ，分别用于四个活动之间的跳转。

 

  < bpel:flow >
<!-- define the links -->
        < bpel:links >
           < bpel:link  name ="receive-to-invoke" />
           < bpel:link  name ="invoke-to-receive" />
           < bpel:link  name ="receive-to-reply" />
        </ bpel:links >

 

 

      在活动中，如果需要跳转，则完成 <source> 标签，指明所使用的 linkName 表示此活动为该链接的源。而如果该活动需要由别的活动跳转到，则需要完成 <targer> 标签，指明所使用的 linkName ，表示此活动为该链接的目标。如下 :

 

       < bpel:receive  createInstance ="yes"  operation ="TravelApproval"  partnerLink ="client"  portType ="cli:TravelApprovalPT"  variable ="travelRequest" >
           < bpel:sources >
              < bpel:source  linkName ="receive-to-invoke" />
           </ bpel:sources >
        </ bpel:receive >
        < bpel:reply  operation ="TravelApproval"  partnerLink ="client"  portType ="cli:TravelApprovalPT"  variable ="travelResponse" >
          < bpel:targets >
             < bpel:target  linkName ="receive-to-reply" />
           </ bpel:targets >
        </ bpel:reply >
        < bpel:invoke  inputVariable ="travelRequest"  operation ="TravelApproval"  partnerLink ="travel"  portType ="trv:TravelApprovalPT" >
           < bpel:targets >
              < bpel:target  linkName ="receive-to-invoke" />
           </ bpel:targets >
           < bpel:sources >
              < bpel:source  linkName ="invoke-to-receive" />
           </ bpel:sources >
        </ bpel:invoke >
