How can you know in which directory a JSP file is?

[Albretch]

Say you put the same JSP in

<%CATALINA_BASE%>/webapps/webappName/Dir00/

and

<%CATALINA_BASE%>/webapps/webappName/Dir99/

How could you make the JSP by itself tell apart 'Dir00' from 'Dir99'?

None of these work:

// __
String aPth = null;
File Fl;
try{ Fl = new File("."); aPth = Fl.getCanonicalPath(); }
catch(IOException IOXcptn) { IOXcptn.printStackTrace(); }
System.err.println(" new File(".").getCanonicalPath()=" + aPth);

// __
aPth = (new File(".")).getAbsolutePath();
System.err.println(" (new File(".")).getAbsolutePath=" + aPth);

Is there any work around?

File Fl;
try{ Fl = new File("."); aPth = Fl.getCanonicalPath(); }
catch(IOException IOXcptn) { IOXcptn.printStackTrace(); }

You drive people nuts by violating the caps coding conventions.

Please see http://mindprod.com/jgloss/codingconventions.html

variables MUST start with a lower case letter.

I mean, how can you achieve it at once from the JspInit part of the servlet

You can do it from a request each time by going:

String aRqPath = request.getServletPath();
String aAppPath = application.getRealPath(aRqPath);
String aPath = new File(aAppPath).getParentFile().getPath();
