java - 以编程方式生成 BPEL 文件？

Question

有没有办法在 Java 中以编程方式生成 BPEL？

我尝试使用 BPEL Eclipse Designer API 编写这段代码:

 Process process = null; 
 try {



        Resource.Factory.Registry reg =Resource.Factory.Registry.INSTANCE;

        Map<String, Object> m = reg.getExtensionToFactoryMap();

        m.put("bpel", new BPELResourceFactoryImpl());//it works with XMLResourceFactoryImpl()



         //create resource

         URI uri =URI.createFileURI("myBPEL2.bpel");



         ResourceSet rSet = new ResourceSetImpl();

          Resource bpelResource = rSet.createResource(uri);



          //create/populate process

          process = BPELFactory.eINSTANCE.createProcess();

          process.setName("myBPEL");

          Sequence mySeq = BPELFactory.eINSTANCE.createSequence();

          mySeq.setName("mainSequence");

          process.setActivity(mySeq);



          //save resource

          bpelResource.getContents().add(process);

          Map<String,String> map= new HashMap<String, String>();
          map.put("bpel", "http://docs.oasis-open.org/wsbpel/2.0/process/executable");
          map.put("tns", "http://matrix.bpelprocess");
          map.put("xsd", "http://www.w3.org/2001/XMLSchema");
          bpelResource.save(map);

    }



    catch (Exception e) {

          e.printStackTrace();

    }


}

但是我收到一个错误:

INamespaceMap cannot be attached to an eObject ...

我读了this message通过西蒙:

I understand that using the BPEL model outside of eclipse might be desirable, but it was never intended by us. Thus, this isn't supported

还有其他 API 可以提供帮助吗？

Answer 1

你可能想给 JAXB一试。它可以帮助您将官方 BPEL XSD 转换为 Java 类。您可以使用这些类来构建您的 BPEL 文档并输出它。
