Re: relative path in servlet

I had much of the same problem with reading a ini-file for a servlet that
can be run
om different  IBM Websphere webservers.

I used the getPathTranslated() method of the HttpServletRequest object.
This method returns the full path of the servlet:
e.g http://www.server.com/MyServlet becomes
C:\Dir\AnotherDir\servlet\MyServlet

This code that goes into the doGet() or something is:

String iniPath = getIniPath (req.getPathTranslated(),"file.ini" );

Then I placed the ini-file (file.ini) in the AnotherDir directory and made
the getIniPath() method:

private String getIniPath(String fullPath, String iniFile)
{
     StringTokenizer st = new StringTokenizer(fullPath,"\\");
     boolean ready = false;
     String nextToken = "";
     String returnPath = "";

     while(!ready && st.hasMoreTokens())
     {
          nextToken = st.nextToken();
          if(nextToken.equals("servlet"))
               ready = true;
          else
               returnPath += (nextToken + "\\");
     }
     return returnPath + iniFile;
}

Works fine when the webserver creates a virtual 'servlet' directory.
Hope this can help some of your problems.

thanks,
it doesn't work. getRealPath(String) cann't return any path.
and what I want is read from a normal virtual directory on webserver into a
servlet mounted directory, is there other way?

thank you very much.

sincerely
