我想从php邮件功能发送电子邮件。这是我的代码

        @Stateless(mappedName = "TestSDO")
        @Remote(TestSDORemote.class)
        @Local(TestSDOLocal.class)

        public class TestSDO implements TestSDORemote, TestSDOLocal{
            ...


        // default EJB constructor

     public TestSDO() {
           String textInfo = "";

            try {
                defineSDOTypes();
            } catch (Exception e) {
                LOGGER.log(Level.WARNING, "Could not define SDO types");
            }
        }
             ...
      private void defineSDOTypes() {
            HelperContext hc =   
            SDO.getHelperContextFactory().createHelperContext("ScopeManagerTestID", 
            null);
            XSDHelper xsdHelper = hc.getXSDHelper();
            try (InputStream is = new BOStorage().getInputStreamXSD("/test.xsd")) {          
                 xsdHelper.define(is, null);    
            } catch (IOException e) { 
              LOGGER.logp(Level.WARNING, CLASS_NAME, METHOD_NAME, "Unable to load the 
              schema: " + 
              "test.xsd" + ": " + e.getMessage());      
               e.printStackTrace();     
            }
             ...
      // creates the target Data Object (here comes the error)
      private void createBO(){
            DataObject dob = DataFactory.INSTANCE.create("http://ejb/package/name", 
            "RefObject");
        }
             ...
