JBPM 错误集锦

1、问题：org.hibernate.exception.ConstraintViolationException: could not delete: [org.jbpm.pvm.internal.model.ExecutionImpl#1]
连接Mysql5时，jBPM4运行到 End结点时的错误，把 hibernate.dialect 改为 org.hibernate.dialect.MySQLInnoDBDialect



2、问题：org.hibernate.HibernateException: instance not of expected entity type: org.jbpm.pvm.internal.type.variable.UnpersistableVariable is not a: org.jbpm.pvm.internal.type.Variable

In case you still got the problem. I also had this error due to the fact the Object I was adding as a variable was not Serializable.

Implementing java.io.Serializable should fix this error.

意思是压入上下文的对象要实现 Serializable接口


3、问题：Caused by: java.lang.ClassNotFoundException: de.odysseus.el.util.SimpleResolver

Requirements

JUEL requires Java 5 or later.

加入juel.jar

-------------------------
I think I get same problem when trying to integrate JBPM4 into my app. And I find out why.
Because you're using Tomcat 6.0... The lib el-api.jar in %tomcat_home%/lib conflicts with juel.jar, which exists in %jbpm4_home%/lib.

juel: <http://juel.sourceforge.net/> You will find the 2 jars define the same api for javax/el/ExressionFactory.

The solution is that you use Tomcat 5.5 instead of Tomcat 6.0. Because tomcat 5.5 uses commons-el.jar (Tomcat5.5/common/lib)

Or you can still use Tomcat 6.0, but you must replace el-api.jar with juel.jar. And don't forget to remove juel.jar from your app lib(A duplicate import, if you don't remove).

Try it!

---------------------------------------------------------
总结：删掉tomcat6的el.jar，加入juel.jar,juel-impl.jar,juel-engine.jar

请问，我的现在出现这种问题，怎么解决。
我就是建了一个请假流程，根本没用到mail，不知道为什么会报这样的问题?求解，谢谢。

6 楼 zhl549342097 2012-04-12  

谢谢  你的错误总结   有帮助到我 

5 楼 jordan421 2011-01-12  

非常感谢你

4 楼 jordan421 2011-01-12  

第一个问题就折磨我很久

3 楼 rprenpeng83 2010-09-09  

thank you very much~

2 楼 koushuizhu 2009-10-26  

User u = new User();
u.setAge(60);
u.setName("boss");
u.setUserName("houqj");
Map<String,Object> jbpmVariables  = new HashMap<String,Object>();
jbpmVariables.put("user", u);

instanceService.startProcessInstance(id,jbpmVariables);


User实现了序列化了

在没集成Spring是能正常运行的，集成了spring后报错：
org.jbpm.pvm.internal.type.variable.UnpersistableVariable is not a: org.jbpm.pvm.internal.type.Variable

1 楼 koushuizhu 2009-10-26  

我序列化了，怎么还报这个错误：Method public java.lang.String org.hibernate.exception.NestableRuntimeException.getMessage(int) threw an exception when invoked on org.hibernate.HibernateException: instance not of expected entity type: org.jbpm.pvm.internal.type.variable.UnpersistableVariable is not a: org.jbpm.pvm.internal.type.Variable
