I have a String that I need to break into parts to use one of the values.

Example:
// This value actually comes from request.getReqestURI();
String uri = "/Servlet/Case.html";

What I need is the "Case" value...it won't always be "Case". The format will always be ContextPath + / + pageName and what I need is the pageName without the .html.

TIA

May I suggest:

String uri = "/Servlet/Case.html";
int lastSlashIndex = url.lastIndexOf('/');
int lastDotIndex = url.lastIndexOf('.');
String name = uri.substring(lastSlashIndex, lastDotIndex);

Good luck.

Much more elegant than what I had =)

I just had to change:
String name = uri.substring(lastSlashIndex, lastDotIndex);
to:
String name = uri.substring(lastSlashIndex + 1, lastDotIndex);

Thanks a bunch!

If you're programming with servlets, you can always ask the request what the context path is rather than parsing it out of the URI.

Right, but in my example, that would just give me /Servlet and I wanted Case. Correct me if I am wrong.

The context path is /jsp-examples!
