Hopefully somebody could point out where I am going wrong...
I am using WAR deployment under Tomcat3.2.1 on a WinNT4 box.
I have placed a file (me.txt) in the WEB-INF directory, and have written the
following servlet which tries to read the file.
public class MercuryServlet extends
Try using HAT (Heap Analysis Tool), you can download it from Sun. It allows
you to take snap shots of the heap at run time and exports it as HTML
pages.. letting you see just how many objects, and of what types have been
created.

This raises a good point, people who put so much work into an open project
such as Tomcat are rarely praised and often have to put up with a lot of
unnecessary flak!
So lets take time out from the 'This Sucks' theme and say THANK YOU TOMCAT!

Best Approach:
In the Servlet 2.3 spec (So Tomcat 4.0) you could use Filters.. a Filter may
be run before or after a Servlet.. modifying what it sees, or what it
returns.

It isn't just 'static' variables that you have to be careful of, normal
instance variables should be avoided too. You see, one instance of a
servlet
may service many many people (often there is only ever one instance of a
particular servlet!).
If you are sharing any data structure between
From
my experience there are 2 things that are worth checking.
1)
Make sure that the database has an instance named orcl in the TNA lookup (test
the connection using Oracle tools, Net8 assistent will do).
2)If you are using 8i, then make sure that orcl
is not a Service Name.. people
Your
problem is the service name, the string you used was meant to use a SID.. try
the following instead, it uses the service name as specified from your
TNS.
jdbc:oracle:thin:@(description=(address=(host=myhost)(protocol=tcp)(port=1521))(connect_data=(service_name=oracle
I don't know enough about your setup to be sure, but I have been hit by a
problem similar to this on a Solaris box running IPlanet. The problem was
that the file holding the translations was stored using a different encoding
to the one that was being used to read in the file. You have to be
You said 'pretty transparent' to tomcat. Where is it not transparent?
Specifically I am wondering about cookies, do cookies work with SSL at all
or is it a possible configuration thing that has to be done correctly?

Beyond the fact that Apache will give you a wealth of options for
at all.

Is that still the case if you disable cookies within a client?
I find that Tomcat doesn't notice that co
There is a solution built into the Servlet standard. Take a look at the

HttpSessionBindingEvent, just implement this interface on the session

Your problem is that your session object (holding the connection) is not
being notified when the session is dropped. nb, when a user closes a browser
is not when the session will be dropped. You'll have to add i) a time out to
the session (say 10 minutes?) and ii) give the user a logout button
Have you tried setting *.htm=ajp12, AND in httpd.conf move the mod_jk

To verify Duncans point:
Cache-Control on the request is for proxies.
Cache-Control on the response is for proxies+browser.

You could try Cache-Control 'no-store', or 'must-revalidate'.. to see if IE

As far as classpaths are concerned, you can think of a jar file as a
directory (not a file). That is, unlike files (.class files especially) you
must explicitly specify the jar file on the class path.
That is, to pick up the servlet jar file, specify the following path. You
will have to do a

Where are you getting the figure '10Megs per thread' from?
Each thread shares the same memory space, that means the 10Megs is shared
between the 46 threads and is not on a per thread basis.

I cann't explain the error message with out knowing more about the code; but
if you are trying to use cookies then that could be your problem. To my
knowledge (and I will point out that I have never tried it; so hopefully
somebody will back me up when I say that) WAP does not support cookies.
For session tracking to work, look at the following 2 methods
resonse.encodeURL
and
response.encodeRedirectURL
In this way, session tracking will only work when following links because
URL re-writting requires a link to modify whereas cookies go by the domain
