newbie: At web servers.
Hi,
With much ado and help from this user group I finally got Tomcat up and
running on my NT server box. Again, many thanx to all. When I type
http://localhost:8080/ I get the example page up. Now my stupid question
is, how do I call that same page from my client machine? I have tried:
http://ServerName:</path/to/tomcat>/webapps/ROOT/index.html and
http://ServerName:8080/ with no success. If I point Windows Explorer to the
index.html file and open it, the page is displayed. However, clicking on
any link does not display anything but a blank page.
Does this mean that I have to install Apache and then configure Tomcat to
work with it if I want to access pages on another machine over my little
intranet?
Thanx,
LeRoi

Hi there,
once you're comfortable with the basics I suggest you have a look
at the Jakarta Ant project, and the docs in the ROOT webapp in
the basics of using it: ant reduces the amount of work you have
to do moving/copying files into and out of directories.

Yup! That worked. Part of the problem for me is that the book I'm using to
learn Java was written just before the Java web server was released to
Jakarta.
Innyway, you've saved me from lots of work until I need to. I'm I've been
reading the documentation on deploying an application. For a newbie, it's a
bit overwhelming right now just to test a simple example.

newbie: Installing Servlets
Posted by LeRoi <le...@blueyonder.co.uk>.
Hello!
Now that I have Tomcat up and running, it's time that I starting doing some
real work. Following a simple example in the book I'm using it says that
servlets are installed in the subdirectory "webapps\WEB-INF\servlets". I
put my class there (under "examples" directory of Tomcat) and shut down
Tomcat and re-started it. Below is the code for textbook example:
// Fig. 19.5: HTTPGetServlet.java
// Creating and sending a page to the client
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class HTTPGetServlet extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
PrintWriter output;
response.setContentType("text/html"); // content type
output = response.getWriter(); // get writer
// create and send HTML page to client
StringBuffer buf = new StringBuffer();
buf.append("<HTML><HEAD><TITLE>\n");
buf.append("A simple Servlet Example\n");
buf.append("</TITLE></HEAD><BODY>\n");
buf.append("<H1>Welcome to Servlets!</H1>\n");
buf.append("</BODY></HTML>");
output.println(buf.toString());
output.close(); // close PrintWriter stream
}
}
<!-- Fig. 19.6: HTTPGetServlet.html -->
<HTML>
<HEAD>
<TITLE>
Servlet HTTP GET Example
</TITLE>
</HEAD>
<BODY>
<FORM
ACTION="http://localhost:8080/servlets/HTTPGetServlet"
METHOD="GET">
<P>Click the button to have the servlet send
an HTML document</P>
<INPUT TYPE="submit" VALUE="Get HTML Document">
</FORM>
</BODY>
</HTML>
Well, it didn't work. My question is, in order to install this simple
servlet does that mean I have to go through all the steps as given in the
documentation for "Developing Applications with Tomcat"?
Cheers and many thanx in advance,

Introduction
DOS (an acronym for Disk Operation System) is a tool which allows you to
control the operation of the IBM PC. DOS is software which was written to
control hardware. IDRISI, Atlas*GIS, Microstation, AutoCAD, CPS/PC, and
ARC/INFO are, in turn, application software which run under DOS. By this we
mean that, although IDRISI, Atlas*GIS, Microstation, AutoCAD, CPS/PC, and
ARC/INFO were written to accomplish a single task or application (in this
case manipulation of spatially related data), they must use DOS to pursue
its work.
DOS can be used for a wide range of tasks far beyond the requirements of
this class. You will be able to manage well if you master only a small
subset of DOS commands and functions. These relate almost exclusively to
file and directory management and are introduced in this handout.
This tip sheet assumes that you have learned how to turn on the PCs as they
are configured in room 230 and that you have familiarized yourself with
their keyboards (no small task in itself). It also assumes that you
understand the meaning of the concept of a file and the elements of a file
specification (drive, filename, and extension). The microcomputers you will
be using are equipped with two floppy disk drives. The A-drive is the 3.5"
(1.44MB) drive and the B-drive is the 5.25" (360KB) drive. The
microcomputers also contain a C-drive, a hard disk drive of 130MB or 200MB
capacity.
You will quickly find that the best way to learn how to use a computer is
through experimentation. That is, once you have learned a command, try some
variations until they don't work, then start over. Often there are five or
six ways for you to accomplish a particular task. Usually, I will introduce
you to only one, leaving it up to you to discover the rest. Don't hesitate
to consult the DOS Reference Manual; copies can be found on the bookcase in
room 230. Finally, don't be unduly disturbed by error messages. With
computers, one of the best ways to learn is by making mistakes.
Most of the common DOS commands you need to use for this class (copy,
rename, delete) are available to you in Windows through the Filemanager
icon. And, since you can move back and forth between DOS and Windows, it
doesn't matter which option you employ. Some commands are faster in invoke
in Windows, some in DOS. If you haven't worked with Windows previously, go
to the Windows tutorials in the help area.
Backup Files
It is possible to lose files by mistake, although the more you practice the
less likely it becomes. For your own peace of mind, it is good practice to
make backup copies of your most valuable files on a separate diskette. Store
your backup disk in a safe place and don't carry it through a metal
detector. Use the COPY command to create the backup.
There is no need to backup every file you create, only the ones in which
you've invested much work. Also, prune your backup diskette every week or
two using the ERASE command. Backup files which have been made redundant by
subsequent additions will simply create clutter on your backup diskette. An
effective file naming convention is essential to keeping track of your
backups.
Change the Default Drive
To change the default drive, simply type the letter of the your choice. The
new default will be listed in subsequent DOS prompts.
Example:
C> A: [enter]
Changes the default drive from C to A.
A> C: [enter]
Changes the default drive from A to C.
[enter] means that you must press the Enter Key before the format command
will execute. [Enter] is required after any DOS command, it is assumed in
all commands found below.
CHDIR (CD) Change Directory Command
Once you have located the directory you want, you may move from directory to
directory using the CD command (change directory)
Example:
C> cd furniture
Moves you to the directory called 'FURNITURE'
C> cd \furniture\chairs
Moves you to the directory called 'CHAIRS' under the directory called
'FURNITURE'.
C> cd ..
Moves you up one level in the path.
C> cd \
Takes you back to the root directory (c: in this case).
COPY Command
The COPY command can be used both to copy files from disk to disk or to
create a second copy of a file on a single disk. (There are many more uses
of the COPY command, but only the basic operation is discussed here.)
Example:
C> copy c:kermit.exe a:
Copies the file 'KERMIT.EXE' from the C drive to the A drive and gives it
the same name.
C> copy a:brazil1.dat b:\south\brazil2.dat
Creates a copy of 'BRAZIL1.DAT' from drive A on drive B, putting it in the
'SOUTH' subdirectory and renaming it 'BRAZIL2.DAT'.
The key to use this command correctly is to remember that the first file
specified after the COPY command is the source file, the second is the
target:ehp1 file. The source is the file to be copied. The target will be
the location and name of the new file. If the file name and extension are
omitted after the target's drive specification, the new file will have
exactly the same name as the source file.
Example:
C> copy a:myfile.txt b:
C> copy c:command.com b:com.com
C> copy b:golly.gee a:whao.boy
C> copy command.* a:
C> copy a:mymap.dwg c:\maps
Note: it is always good practice to us the complete file specifications for
both source and target files, Be very sure of yourself before you accept
defaults or employ wild-card characters. Otherwise you may end up with some
interesting results. Incomplete or incorrect source names may result in
errors, such as the command: copy edlin a:myomy.bat. Try it and see what
happens.
DIR (Directory) Command
The DIRECTORY command lists the names and sizes of all files located on a
particular disk.
Example:
C> dir a:
Shows directory of drive A
C> dir b:
Shows directory of drive B
C> dir \agis
Shows files in a subdirectory on drive C (default)
C> dir
Shows directory of drive C
C> dir /w
Shows directory in wide format, as opposed to a vertical listing.
All the files are listed at the screen, you can stop the display by typing
CTRL-BREAK. If you ask for a directory on the A or B drives, be sure there
is a diskette in the drive and that the diskette has been formatted. If the
drive is empty, or if the diskette is unformatted, the DOS will respond with
an error message.
DIR Options
Two little characters, '*' and '?', will make your life with computers much
easier. Their use is illustrated below.
Example:
C> dir a:*.ex
Lists all files on the A drive with an extension of 'EXE'.
C> dir b:kermit.*
Lists all files on the B drive with a filename of 'KERMIT'.
The asterisk is a wild-card character which allows the user to enter only a
limited part of a file specification to find a file. It is useful when you
wish to locate a group of files with the same filename or the same
extension. On other occasions you may have forgotten part of a file
specification. You can use '*' in place of the parts of the specification
you have forgotten. Similarly, '?' permits wild-card searches keyed to
single characters.
Example:
C> dir a:labe?.com
Lists all five-letter files with the first four letters 'LABE' and an
extension of 'COM'.
C> dir b:format.c??
Lists all files with a filename of 'FORMAT' and an extension beginning with
'C'.
Wild-card characters can be used in combination.
Example:
C> dir a:labe?.*
Lists all five-letter files with the first four letters 'LABE' and any
extension.
C> dir c:*.ex?
Lists all files with an extension beginning with 'EX'.
Experiment with '*' and '?' to improve your ability to find files quickly.
These wild-card characters can also be used with several other DOS commands.
ERASE Command
The ERASE command deletes specified files.
Example:
C> erase a:myfile.txt
Erases the file MYFILE.TXT from the diskette in the A drive. If no drive
specification is entered, the system looks to delete the specified file form
drive C (in this case).
IMPORTANT WARNING: This command is easy to use, but it is the most dangerous
one you will encounter in DOS (apart form FORMAT). If you aren't careful,
you may delete a file which you--or someone else--needs. And, unless you
have saved a backup of that file, the erased file is gone for good. For this
reason it is good practice to use only complete file specifications with the
ERASE command (and to keep backups of your most valuable files). As a safety
precaution, never use the wild-card characters '*' and '?' in ERASE
commands.
BEWARE: I will rescind your laboratory privileges for a full week if you
ever knowingly use either the command: erase c:*.*, or the command: erase
*.*. Guess what happens?
File-Naming Conventions
Careful file naming can save time. Always choose names which provide a clue
to the file's contents. If you are working with a series of related files,
use a number somewhere in the name to indicate which version you have
created. This applies only to the filename parameter; most of the file
extension parameters you will be using are predetermined (or reserved by DOS
for certain types of file).
Example:
WORLD.DAT
An ATLAS*GRAPHICS file containing data for a world map. The DAT extension is
required by ATLAS*GRAPHICS.
BRAZIL.BNB
A boundary file of Brazil in binary form.
BRIT1.DAT
BRIT2.DAT
BRIT3.DAT
Three versions of a data file for a map of Britain.
FORMAT Command
You must format new disks before using them on the IBM computers. The format
command checks a diskette for flaws and creates a directory where all the
names of the diskette's files will be stored.
Example:
C> format a:
Formats the diskette in the A drive.
C> format b:
After entering this command, follow the instructions on the screen. When the
FORMAT operation is complete, the system will ask if you wish to FORMAT more
diskettes. If you are working with only one diskette, answer N (No) and
carry on with you work. If you wish to FORMAT several diskettes, answer Y
(Yes) until you have finished formatting all your diskettes.
BEWARE: Executing the format command with a diskette which already contains
files will result in the deletion of all the contents of the entire disk. It
is best to execute the format command only on new diskettes. If you format
an old diskette make sure it contains nothing you wish to save.
MKDIR (MD) Make Directory Command
This command creates a new directory.
Example:
C> mkdir mine
Creates a directory called 'MINE'
Rebooting the computer (Ctrl-Alt-Del)
In some cases, when all attempts to recover from a barrage of error messages
fails, as a last resort you can reboot the computer. To do this, you press,
all at once, the control, alternate and delete.
BEWARE: If you re-boot, you may loose some of your work--any data active in
RAM which has not yet been saved to disk.
RENAME (REN) Command
The RENAME command permits users to change the name of a file without making
a copy of it.
Example:
C> ren a:goofy.txt pluto.txt
Changes the name of 'GOOFY.TXT' on the A drive to 'PLUTO.TXT'.
This command is very simple to use, just remember two points: the file name
and extension must be complete for the source file and no drive
specification is given for the target. Renaming can only occur on a single
disk drive (otherwise COPY must be used).
RMDIR (RD) Remove Directory Command
This command removes a directory. It is only possible to execute this
command if the directory you wish to remove is empty.
Example:
C> rd mine
Removes directory called 'MINE'.
Stop Execution (Ctrl-Break)
If you wish to stop the computer in the midst of executing the current
command, you may use the key sequence Ctrl-Break. Ctrl-Break does not always
work with non-DOS commands. Some software packages block its action in
certain situations, but it is worth trying before you re-boot.

Guys, would someone pls post/attach a working copy of subject file?
Sorry to be a bother, but without a working knowledge of the DOS syntax
here, and the documentation's use of conventions to refer to
_your_directory_ etc, I can't always tell one from t'other, and I want to
ensure that my foundations is right - so as to further bother you all the
least. Thanks, all.

Dim!
You're a bloody STAR mate! That worked a treat! I think I'll stop while
I'm ahead and pick up on this stuff tomorrow. Enjoy the rest of your day!
And, a BIG thanx for your help.

LeRoi,
localhost is merely an alias for the loopback device (127.0.0.1). find
out what the ipaddress of your machine is. I'm assuming you're on
windows, I think the command is ipconfig on win98, or winipcfg on nt.
you'll need to type this at the command prompt rather than clicking on
the file, so (excuse me if I'm patronizing), go Start Menu -> Run ->
command, then when you're at the command prompt type ipconfig, it should
show you a series of numbers, the first of which (I think) is you're ip
address. to check this, replace localhost with it to get the example
page up. this will then work from any computer (depending on the
network you're on).
hope this helps
cheers
