以下代码片段显示了 getProcessModel 和 getInstanceAuditTrail 方法。

　　getProcessModel 方法

/** * This function gets the debugger XML model of a given BPEL process. * * The function returns the xml model. * * * @param strProcessID *            the business process name. * @return the xml process model. */ public String getProcessModel(String strProcessID) {  System.out.println("getProcessModel - " + strProcessID);  String strProcessModel = "";  try {   IBPELProcessHandle process = getLocator().lookupProcess(     strProcessID);   // Returns the debugger XML model of this BPEL process.   strProcessModel = process.getProcessModel();  } catch (Exception e){   e.printStackTrace();   strProcessModel = ERROR_STRING;  }  return strProcessModel; } getInstanceAuditTrail 方法 /** * This function gets the XML audit trail of a given BPEL process. * * The function returns the xml model. * * * @param strProcessID *            the business process name. * @return the xml process model. */ public String getInstanceAuditTrail(String strInstanceReferenceID) {  System.out.println("getInstanceAuditTrail - " + strInstanceReferenceID);  String strResponse = "";  try {   IInstanceHandle instance = getInstance(strInstanceReferenceID);   // Returns the XML representation of the audit trail of this   // instance.   strResponse = instance.getAuditTrail();  } catch (Exception e){   e.printStackTrace();   strResponse = ERROR_STRING;  }  return strResponse; }
