我发出错误信息，将返回值替换为0(请记住：每个内联代码块都返回一个对象)。

I emit an error message and replace the return value with 0, instead (remember: every inline code block returns an object).

如果忘了这最后一步的话(我几乎每一次在Grails中使用EJB3注释时都会忘记这一步)，会得到如下的错误信息。

If you forget this final step (I do nearly every time I use EJB3 annotations in Grails), you'll get the following error message.

我被搞懵了，接下来我能记得的，就是看见一些数字符号啥的出现了，最后出现一个错误信息，像是'文件格式无效'什么的。
