Hey,

1. In directory match was is necessary to have the end slash also.

eg:



is this servlet match with the following request as directory match?
http://localhost/Test/abc (no end slash like /abc/)


2.It was said that if a request match more than one url-pattern container will choose the longest mapping also it was said container will first look for exact match , directory match and then extension map. so its kind of contradictory know? since the exactly match is the longest this wouldnt be a problem? but what if we choose both exact and directory match have the same length.
eg:

In this case the exact match will always win.

As for the slash, a mapping of /dir/* and a request of http://localhost:8080/PROJECT_NAME/dir will also map to the corresponding servlet.

Ive found this article also it says if that slash not there it will need a exact macth..


That would be an unmatched pattern since the * would not be a wildcard, but must be an exact match
