我有一个奇怪的问题.在Eclipse Ganymede中,我曾经能够突出显示一个变量,并强调在该方法中使用这些变量.但是通过一些动作我现在禁用了它.有没有办法可以启用它？
我试着搜索谷歌,但由于我不知道这个功能叫什么,它有点难.
它是一个非常有用的功能,它令人烦恼,它无法正常工作.
有谁知道我在哪里可以获得JSF使用的转换器列表,所以我可以在资源包中为它们设置自定义消息？
在eclipse中是否有插件可以输入快速的java代码示例并运行它？我记得很久以前就看过这样的事了.
我在我的Myfaces 2应用程序中进入实例化异常.但是通过log4j进行的异常打印正在切断堆栈跟踪的其余部分.这是我所看到的:

我无法找到更改配置的位置,因此我可以看到"... 48以上".有任何想法吗？
