捕获低级类引发的消息。

Question

我的应用程序有四个层次：(1)我的应用程序，(2) pivot4j，(3) olap4j，(4) Mondrian

如果我在Scala中运行这段代码：

try {
     renderer.render(model, new HtmlRenderCallback(sw)) 
}
catch {
  case ex: Exception => println(ex.getMessage)
}

应用程序打印pivot4j引发的错误：

org.olap4j.OlapException: mondrian gave exception while parsing query

如果我没有捕捉到错误，堆栈跟踪是(用粗体显示相关消息)：

Mondrian是该错误的始发者，我需要得到抛出的消息：

 MDX object '[Measures].[Unit Cost]' not found in cube 'Sales'

我试过：

try {
     renderer.render(model, new HtmlRenderCallback(sw)) 
}
catch {
  case ex: MondrianException => println(ex.getMessage)
}

但并没有发现错误。

使用Apache获取根异常。
