如何在eclipse中使用spring和mysql DB配置JBPM 6

Abh*_*yak 5 spring jpa drools jbpm kie

我正在尝试集成spring和JBPM,我做了谷歌的示例应用程序,发现一个github项目解释相同.

使用的框架版本:

  • Spring 3.1.1.RELEASE
  • JBPM 5.4.0.CR1
  • 流口水5.5.0.CR1

我已经将github项目导入eclipse工作区,并且在maven clean之后我得到例外说:

Listed class "org.jbpm.task.Status" must not be an enum persistence.xml /jbpm-spring-web/src/main/resources/META-INF    line 30 JPA Problem
Run Code Online (Sandbox Code Playgroud)

和src/main/resources/META-INF/Taskorm-JPA2.xml文件中的一些JPA查询异常如:

The abstract schema type 'OrganizationalEntity' is unknown. Taskorm-JPA2.xml    /jbpm-spring-web/src/main/resources/META-INF  line 375  JPA Problem

和 

The IN expression does not have a valid left expression.    Taskorm-JPA2.xml    /jbpm-spring-web/src/main/resources/META-INF    line 7  JPA Problem

如何解决这些异常？
