Worklight 6.1日志中的JPA错误：无法启动应用程序

时间：2014-04-01 17:13:54

标签： ibm-mobilefirst worklight-server

我有WL 6.1 Studio（在RAD 9.0.1上面）+ WAS Liberty Profile 8.5.5.1 + WL 6.1 + Derby DB。

在某个时间点我开始收到错误并且我的WL应用程序无法启动，从WAS日志开始看似JPA（或JPA类加载冲突）的问题？

我可以检查什么来修复它？

以下是日志文件中的相关片段（应用程序无法启动）

答案 0 :(得分：0)

异常是由于Liberty运行时的类发生冲突问题。加载的类取决于您在Liberty概要文件server.xml文件中定义的功能。 Worklight发生冲突，例如当启用open-jpa和jax-rs功能时（并且设置parentLast委派不能解决问题） 你使用哪个功能？
