第7章介绍的报销及采购流程的完整工程及其源代码: jbpm-web-test.rar
第9章企业级应用里涉及到的工程及相关EJB的源代码：jbpm-ent-test.ear.rar
我发现ManagerAssignment这个handler根本没有被调用，请高老师解释下
要在 destinations-service.xml 配置文件中配置队列吗？

高老师 您好 我有个问题，就是第一个流程我创建实例的时候我后台打出下面部分后没有报错，但是我查了下jbpm_taskinstance这个表 没有任务实例数据，创建实例没成功，麻烦帮我看下，谢谢

同问167楼的。第七章的采购流程实例。
看了高老师的jbpm的mail配置，怎么发邮件不用用户名、密码啊。一直报错，和167楼的一样的错

高老师，首先感谢你出的这本《深入浅出jBPM》，对我帮助很大。不过，我是入门新手，在认真看本书中遇到一些问题，希望你帮助解决一下：
我从第一章看到第七章（目前看到第七章），所有的例子基本都可以正常运行，也仔细的按照书中所写的内容实现了相当的代码，不过，也发现一些问题，都是与邮件发送有关的。
问题分别来自：
1、第107-111页的mail node节点示例
2、第127-131页的tasknotify流程示例
3、第七章的采购流程示例中的邮件发送功能
以上3处问题都出现在邮件发送失败。
按照书中所写，配置jbpm.cfg.xml（已放在classpath下），增加内容：
<string name="jbpm.mail.smtp.host" value="smtp.gmail.com"/>
<bean name="jbpm.mail.address.resolver" class="test.TestMailResolver" singleton="true"/>
<string name="jbpm.mail.from.address" value="liyunqi168@gmail.com"/>
以上内容，我当然改成了自己所使用的邮箱，
，
我当时也在想，这样应该是不能发邮件吧，理由是：邮件的用户名和密码都没有配置出来，这样就能发邮件了吗，感觉不行？
果然在测试是发送不了邮件，报出程度异常错误，如：运行第七章的采购流程示例TestPurchaseProcess.java报错如下：

另外，我也查看了高老师这里前面的几个回贴，如你回的第26楼贴，说这样配置：
<string name="jbpm.mail.smtp.host" value="smtp.gmail.com" />
<!-- 配置邮件来源地址 -->
<string name="jbpm.mail.from.address" value="aaa@gmail.com" />
<!-- 邮件安全验证 -->
<string name="jbpm.mail.smtp.auth" value="true" />
<!-- 用户名 -->
<string name="jbpm.mail.user" value="aaa@gmail.com" />
<!-- 密码 -->
<string name="jbpm.mail.password" value="****" />
我参考了这里的方法，我更改成这样依然邮件发送不成功。
另，又有回帖说，更改jBPM源码org.jbpm.mail包下的Mail.java文件，这一步，我没有试过，不知真的能否成功。
相信其他书友也遇到同样的问题，
麻烦高老师把邮件发送的这个功能详细指点一下，谢谢！

刚才翻阅前面的同志出现的异常和我的很像，高老师说是否把变量ISSEU_PERSON放入流程实例当中，看后果然发现是个错误。
于是我尝试着修改拉Constans.java中,String final ISSEU_PERSON="issueperson"
或者把流程其他文件里的issueperson改为issue_person则都不会使junit报错。
但是无论修改于否，整个流程只能进行到部门经理这个环节，不能向下进行。
我也尝试修改TestProcess.java中关于关于部门经理是否同意的参数，调整为不同意，但是仍然流不到财务报销结果的Node当中，望指教啊。。。
是不是就是
package test.assignment;
import org.jbpm.graph.exe.ExecutionContext;
import org.jbpm.taskmgmt.def.AssignmentHandler;
import org.jbpm.taskmgmt.exe.Assignable;
import test.Constants;
public class ManagerAssignment implements AssignmentHandler,Constants
{
public void assign(Assignable assignable, ExecutionContext executionContext) throws Exception
{
//从当前流程实例上下文中取得当前报销人
String issueperson = executionContext.getContextInstance().getVariable(Constants.ISSUE_PERSON).toString();
if(issueperson.equals("user1"))
{
//当前报销人为user1,部门经理为manager1;
assignable.setActorId("manager1");
}
else
{
//当报销人为其他人时manager2
assignable.setActorId("manager2");
}
}
}
当中String issueperson = executionContext.getContextInstance().getVariable(Constants.ISSUE_PERSON).toString();
无法获取ISSUE_PERSON在上下文当中的传进来的数据呢？怎么可以传进来呢？
还有，如果有可能的话，能不能发一份带有第一个报销流程的TestPaymentProcess.java的文件给我呢，谢谢拉。

刚才翻阅前面的同志出现的异常和我的很像，高老师说是否把变量ISSEU_PERSON放入流程实例当中，看后果然发现是个错误。
于是我尝试着修改拉Constans.java中,String final ISSEU_PERSON="issueperson"
或者把流程其他文件里的issueperson改为issue_person则都不会使junit报错。
但是无论修改于否，整个流程只能进行到部门经理这个环节，不能向下进行。
我也尝试修改TestProcess.java中关于关于部门经理是否同意的参数，调整为不同意，但是仍然流不到财务报销结果的Node当中，望指教啊。。。
是不是就是
package test.assignment;
import org.jbpm.graph.exe.ExecutionContext;
import org.jbpm.taskmgmt.def.AssignmentHandler;
import org.jbpm.taskmgmt.exe.Assignable;
import test.Constants;
public class ManagerAssignment implements AssignmentHandler,Constants
{
public void assign(Assignable assignable, ExecutionContext executionContext) throws Exception
{
//从当前流程实例上下文中取得当前报销人
String issueperson = executionContext.getContextInstance().getVariable(Constants.ISSUE_PERSON).toString();
if(issueperson.equals("user1"))
{
//当前报销人为user1,部门经理为manager1;
assignable.setActorId("manager1");
}
else
{
//当报销人为其他人时manager2
assignable.setActorId("manager2");
}
}
}
当中String issueperson = executionContext.getContextInstance().getVariable(Constants.ISSUE_PERSON).toString();
无法获取ISSUE_PERSON在上下文当中的传进来的数据呢？怎么可以传进来呢？
还有，如果有可能的话，能不能发一份带有第一个报销流程的TestPaymentProcess.java的文件给我呢，谢谢拉。

请问是不是还要手工配置队列：JbpmCommandQueue
原因？

高老师，你好！买了你的书，并对第七章的应用进行了部署，感觉很有收获。但目前有个问题：在查看流程进度的时候，process-image.jsp页面老是出现问题。如，org.apache.jasper.JasperException: javax.servlet.ServletException: org.dom4j.DocumentException: Error on line 24 of document : Element type "node" must be followed by either attribute specifications, ">" or "/>". Nested exception: Element type "node" must be followed by either attribute specifications, ">" or "/>".
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:522)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:398)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:337)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:266)
javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
但之前发布的流程，有成功显示过。个人感觉是解析gpd.xml文件的时候出现问题，但经过修改乱码问题后，目前好像没错。
谢谢！
