Why does ServletContext#getRealPath("/") return a relative path?
提问by Jan Hoeve
I have the following snippet of code:
我有以下代码片段：
String path = servletContext.getRealPath("/");
Now I got a bugreport from a user saying that the returned path is not an absolute path.
The returned path is 'usr/local/...' instead of '/usr/local/...', so getRealPathseems to be returning a relative path.
现在我收到一个用户的错误报告，说返回的路径不是绝对路径。返回的路径是 ' usr/local/...' 而不是 ' /usr/local/...'，因此getRealPath似乎返回的是相对路径。
I can see this, because the returned path is logged into a logfile.
我可以看到这一点，因为返回的路径已记录到日志文件中。
My specs are:
我的规格是：
- JBoss 4.0.5.GA
- Redhat EL 4
- jdk 1.5.0
- JBoss 4.0.5.GA
- 红帽 EL 4
- JDK 1.5.0

Something like
就像是
String path = new File(servletContext.getRealPath("/")).getAbsolutePath();
should solve your problem. (It does not answer your Question though...;-) )
应该可以解决您的问题。（虽然它没有回答你的问题......;-)）
