在tomcat容器中启动REPL

Question

我正在尝试在tomcat容器中启动scala REPL（2.9.1）并收到以下错误

Failed to initialize compiler: object scala not found.
Note that as of 2.8 scala does not assume use of the java classpath.
For the old behavior pass -usejavacp to scala, or if using a Settings
object programatically, settings.usejavacp.value = true.

我尝试了多种解决方案，例如settings.usejavacp.value = true等，类路径设置但仍然得到相同的错误。有人可以建议解决这个问题吗？

从wicketstuff控制台项目启动scala解释器也会出现同样的错误（scala-console-issue-ref）。
