lifxue 您好，看到你的问题所在，在NotifyPurchaseAction.java这个类当中并没有用到jBPM里的Mail.java来发送邮件，可以看到在NotifyPurchaseAction.java这个类当中发送邮件是手工编写的，很明显没有添加smtp验证，请手工修改一下这个类，添加smtp验证即可，至于如何添加，可以在google上搜关键词“javamail stmp验证”有很多这方面的讨论。

您好，执行到task-list.jsp中的：
List taskList=jbpmContext.getTaskList(currentperson);
出现错误：
currentperson=user1
2009-12-27 18:10:30 org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet jsp threw exception

但是我看了，我导入的j2ee包中是有这个类的。
我服务器使用的是tomcat
List taskList=jbpmContext.getTaskList(currentperson);

你的书读了一个星期，然后下了你的第7章jbpm-web-test.rar的工程，配了一个晚上都还有错，好像该项目还少了好多文件，例如jbpm.cfg.xml，hibernate配置文件，jbpm-process-upload-servet等等，虽然我按书的示例手打了很多，不过难免有漏的，希望老师能给一份完整可以运行的项目给我们
老大，下载的工程里根本就没有'jbpm.cfg.xml' 这个文件
jacky6024 写道
org.jbpm.JbpmException: couldn't parse jbpm configuration from resource 'jbpm.cfg.xml'
看看是不是你的jbpm.cfg.xml文件没有配置或是配置不正确。

您好，从这个错误当中可以看到是test.assignment.ManagerAssignment.assign(ManagerAssignment.java:13) 这个类的第13行出错，从代码当中可以看到，13行要从流程上下文中取到与变量“ISSUE_PERSON”对应的流程发起人，这里应该是该变量对应的值在流程上下文当中不存在，所以后面的toString才有一个空指计的异常，请确认您在流程开始时是否将这个变量放入流程上下文，谢谢。

您好，
“java.lang.ClassNotFoundException: class 'test.assignment.ManagerAssignment' ”
从异常当中可以看到test.assignment.ManagerAssignment这个类没找到，请确认这个类是否被编译到web-inf/classes目录下，如果没有请配置您的classpath及JRE即可。

感谢楼主，我的Java功底不深，请楼主多帮助。控制台信息并未全部贴出，如果您还需要其它信息，我再继续向您说明。

您好，在jbpm-web-test运行时，我填好报销单后，点“提交报销”，页面就会出现如下错误：
HTTP Status 500 -
--------------------------------------------------------------------------------
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: Exception in JSP: /write.jsp:33
30: ti.setVariable("remark", remark);
31:
32:
33: ti.end();
34:
35: } finally {
36: jbpmContext.close();
而将write.jsp中代码第32行ti.end()去掉，就不出现这一错误。请问这是为什么？

82 85 91楼的邮件问题
请教一下作者，问题是否和NotifyPurchaseAction.java有关？
这个文件中有一段代码如下：
//开始发送邮件
Properties mailServerProperties = new Properties();
//初始化mail信息
String smtpServer = JbpmConfiguration.Configs.getString("jbpm.mail.smtp.host");
mailServerProperties.put("mail.smtp.host", smtpServer);
Session session = Session.getDefaultInstance(mailServerProperties, null);
MimeMessage message = new MimeMessage(session);
需要说明一点的是82楼的错误信息，是在“提交采购单”的步骤报出来的。
而NotifyPurchaseAction.java是在“结束”节点上使用的。

lifxue 您好，看到你的问题所在，在NotifyPurchaseAction.java这个类当中并没有用到jBPM里的Mail.java来发送邮件，可以看到在NotifyPurchaseAction.java这个类当中发送邮件是手工编写的，很明显没有添加smtp验证，请手工修改一下这个类，添加smtp验证即可，至于如何添加，可以在google上搜关键词“javamail stmp验证”有很多这方面的讨论。
