webService接口的開發實例job調度功能（工作記錄以后參考和改進）：

項目A中的JOB 調度項目B中的JOB（用同一個quratz用戶），啟動兩個項目的JOB

項目A（客服端）：CommonJob.class

package com.x.x.common.job;

import java.net.MalformedURLException;
import java.net.URL;

import org.codehaus.xfire.client.Client;
import org.quartz.Job;
import org.quartz.JobDataMap;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

import com.x.x.common.util.StaticUtils;

public class CommonJob implements Job {

private Client client = null;

public Client getClient(){
  if( client == null ) {
   try {
    System.out.println("客服端中對smct_job 調度開始建立會話之前查詢調度地址URl!");
    //String smctJobInvokeUrl ="http://10.109.4.230:8080/smct/services/jobInterfaces?wsdl";
    //String smctJobInvokeUrl ="http://10.108.226.193:8080/smct/services/jobInterfaces?wsdl";
    String smctJobInvokeUrl = StaticUtils.getSmctJobInvokeWsdlURL();//可以配置在perporties文件中/數據庫中
    System.out.println("smctJobInvokeUrl:"+smctJobInvokeUrl);
    System.out.println("客服端中對smct_job 調度開始建立會話之前查詢調度地址為:!"+smctJobInvokeUrl);
    client = new Client( new URL(smctJobInvokeUrl) );
    client.setTimeout( 5000 );
    System.out.println("客服端中對smct_job 調度成功建立會話!");
   } catch (MalformedURLException e) {
    e.printStackTrace();
    System.out.println("客服端中對smct_job 調度建立會話失敗!");
   } catch (Exception e) {
    e.printStackTrace();
    System.out.println("客服端中對smct_job 調度建立會話失敗!");
   }
  }

return client;
}

public void execute(JobExecutionContext context) throws JobExecutionException {
  String result = "";
  try {
     JobDataMap jobDataMap =  context.getMergedJobDataMap();

String clazz = jobDataMap.getString("clazz");
System.out.println("客服端對 SMCT JOB 使用類方法"+clazz+": invokeMethodAutoExcute 調度結束:"+result);

   Object[] objs = getClient().invoke("invokeMethodAutoExcute", new String[]{clazz});
   if( objs != null && objs.length == 1 ){
     result = objs[0].toString();
   }
   System.out.println("客服端對 SMCT JOB 使用類方法: invokeMethodAutoExcute 調度結束:"+result);
   } catch (Exception e) {
   System.out.println("客服端對 SMCT JOB 使用類: invokeMethodAutoExcute 調度失敗:"+result);
   e.printStackTrace();
  }
}

}

項目A中配置job類Action method:

public void addAutoJob(HttpServletRequest request, HttpServletResponse response) throws RemoteException,Exception{
  response.setContentType("text/json;charset=GBK");
  String jobname = request.getParameter("jobName");
  String jobgroup = request.getParameter("jobGroup");
  String trigname = request.getParameter("triggerName");
  String triggroup = request.getParameter("triggerGroup");
  String clazz = request.getParameter("className");
  String expression = request.getParameter("CronExpression");
  JSONObject json = new JSONObject();
  try {
         ServiceManager.getSession().startTransaction();

         SchedulerFactory sf = new StdSchedulerFactory();
         Scheduler sched = sf.getScheduler();
         JobDetail jobDetail =

                new   JobDetail (jobName,jobGroup,com.x.x.common.job.CommonJob.class);
         jobDetail.getJobDataMap().put("clazz", clazz);
       CronTrigger cronTrigger =

                 new CronTrigger(trigName, trigGroup, jobName, jobGroup, expression,TimeZone.getTimeZone( "Asia/Shanghai" ));
        sched.addJob(jobDetail, true);
        sched.scheduleJob(cronTrigger);
       sched.start();

ServiceManager.getSession().commitTransaction();

   json.put("retVal", "Y");
   json.put("retMsg", "設置調度成功");
  } catch (Exception e) {
      e.printStackTrace();
         try {
                  ServiceManager.getSession().rollbackTransaction();
              } catch (Exception e2) {
               } finally {
                 json.put("retVal", "N");
                 json.put("retMsg", "設置調度失敗");
                }
  }
  response.getWriter().print(json.toString());
}

項目B接口函數（服務器端）：

public class ParseWebserviceSVImpl implements IParseWebserviceSV {
   public String invokeMethodAutoExcute(String clazz) {
         String flag = "failure";
          try {
         System.out.println("============smct_JOB webService Start=================");
         System.out.println(" 進入接口類ParseWebserviceSVImpl對 smct_JOB 調度類反射,創建job實例開始.");
         System.out.println(" 進入接口類ParseWebserviceSVImpl對 smct_JOB 調度類反射,創建job實例開始.");
         Job job = (Job)Class.forName(clazz).newInstance();
         System.out.println(" 進入接口類ParseWebserviceSVImpl對 smct_JOB 調度類反射,創建job實例結束.");
         System.out.println(" 進入接口類ParseWebserviceSVImpl對 smct_JOB 調度開始執行開始!");
           job.execute( null );
          flag = "success";
  } catch (Exception e) {
          e.printStackTrace();
  }
    System.out.println("接口類ParseWebserviceSVImpl對 smct_JOB 調度開始執行結果標示符('failure'或者'success')為:"+flag);
    System.out.println("=========smct_JOB webService end=====================");
      return flag;
}
