spring+quartz实现任务调度时,抛出奇怪异常

Question

问个spring任务调度的问题，用spring+quartz实现定时发邮件，发邮件类autoSendingMailJob在main里能正常工作，而单单独测试quartz框架system.out也能正常打出，就是把new autoSendingMailJob().start() 放入quartz的executeInternal方法中执行的时候就会抛出
invalid SHA1 signature file digest for javax/activation/DataContentHandlerFactory.class异常，是什么问题呢 请高手指教以下是我的测试任务在ecuteInternal调用spring注入的发邮件的组件public class TestJob extends QuartzJobBean{
public static Logger log = Logger.getLogger(TestJob.class); private autoSendingMailJob asmj;

public void setAsmj(autoSendingMailJob asmj) {
this.asmj = asmj;
} protected void executeInternal(JobExecutionContext arg0)
throws JobExecutionException {
// TODO Auto-generated method stub
try {
log.info("自动发送邮件任务开始>........");
asmj.start();
log.info("自动发送邮件任务结束!");
} catch (Exception e) {
log.error("自动发送邮件任务出现异常", e);
}
}

Answer 1

javax/activation/DataContentHandlerFactory.class这个类所在jar包，是个signed的包，不能修改，如果修改了，就抛这个异常。

javax/activation/DataContentHandlerFactory.class这个类是在activation.jar里这个jar我从来就没动过,我后来把这个jar换了几个版本,结果异常还是一样的,郁闷死了下面是我的配置文件:<?xml version="1.0" encoding="UTF-8"?>
