Re: Tomcat memory-leak problem

[Sam Newman]

I too have been having some problems with Tomcat + 
memory. I put it down to me running win98 and win98 not properly being able to 
address memory over 128MB. I normally have dreamweaver, netbeans and tomcat 
running, and reguarly run out of memory (I have  384MB Ram). I haven't 
noticed any similar problems running tomcat on linux (with a lower spec 
machine). Windows does have memory management issues however, and it might be 
the way tomcat threads means it causes problems with memory on win32 platforms. 
I downloaded Tweakall in the end, as this comes with a niffty utility which can 
free leaked memory.

  Subject: Tomcat memory-leak problem
  
  Hi!
   
  I'm using apache, tomcat jakarta 3.2.1, 
  jdk1.2.2 on a linux 6.2 and a MS SQL server on a Nt4 with sp 
  6a.
   
  Having some trouble with memory-leak. After the 
  server has been running for a couple of days, it has eaten up all 512MB of 
  RAM. It is a server with some customers on and it handles about 1000 visitors 
  a day. We use JSP pages and servlets to show webpages. Servlets primary for 
  showing images from database or generating menues...
   
  So... what shall i do? It doesnt help to restart 
  tomcat. I need to reboot the server and start tomcat all over before we can 
  get in contact with the sites again.
   
   
  Thanks in adv.

Re: Remote logging?

[Sam Newman]

You might want to consider using log4j (another jakarta project). Its manual
has brief converage of using it with tomcat, although I must admit up to now
I've only used Log4j in standalone applications.

Re: Apache - Tomcat - Servlet Mapping

[Sam Newman]

Right - firstly, don't use JServ, use mod_jk. The file 'tomcat-apache.conf'
is generating directives for the old jserv module and its quite possible
this isn't complete. Secondly, Tomcat automatically generates the apache
directives based on your tomcat config for mod_jk (server.xml and web.xml's)
and puts it in a file called mod_jk.conf-auto, which you can include in your
httpd.conf for apache. For more in-depth information check the docs that
come with the tomcat distro - namely the mod_jk howto. The only thing to
watch when using mod)jk.conf-auto is that it only uses ajpv12, which is
slower than ajpv13 (and has a few bugs), so you'd probably want to mount
using the newer ajpv13.

perhaps if we came up with a general consensus as to how to split the lists,
we might get more of a response? As a first draft proposal, what about the
following division:

tomcat-config - for deploying webapps (web.xml, war files), working with
server.xml, running on various platforms etc
tomcat-integration - for working with other webservers, EJB containers,
databases etc.

Please feel free to comment

My single bigest complaint is that when there is a problem with the syntax
(e.g. in web.xml) the error is typically not very informative. This in
itself leads to allot of problems.

Re: I need help in tomcat configuration with Oracle 8.1.7

[Sam Newman]

I don't know anything too specific about use with 
Oracle, but I've certainly used servlets/JSP's to access DB's via JDBC in the 
past (read: maintained code which did it, not developed it!), so its certainly 
possible. Firstly, could you give the exact error you are getting from tomcat? 
Also, you might want to try using 3.2.2, which is the current stable release and 
might contain fixes to your problems already.

Re: Does Tomcat needs jdk 1.2.2

[Sam Newman]

erm, my understanding is that Tomcat only requires Java 1.1.7 or above. By
default the server.xml that ships with Tomcat actually comments out those
areas of code that require Java 1.2/Java 2, e.g. the use of a security
manager/policies

I have no problem with "giving" to the community - its just that I've got
tired of answering the same questions again and again, and if I answered
every question that I had an answer for I wouldn't get any work done (like
most/all of us here I do have a full time job). Because I saw the same
questions coming up again and again I decided to get involved with the
tomcat-book project (which has had to take a back-burner for me at the
moment due to things going mental at work).  The fact remains that general
discussion as to servlet development DOES take place here, which leads me to
believe that there may be a place for a decent developmnet mailing list. Now
this (jakarta) might not be the best place to host it I'd admit, and if
anyone knows of a decent list which already exists that covers
servlet/jsp/taglib development, please let me know. On a related note I know
for a fact that the jakarta-taglib list contains probably 50% general taglib
discussion as opposed to specific stuff about the jakarta taglibs.
As to the general config issues for tomcat, there still might be some scope
for splitting the list - perhaps one for general issues, and one covering
integration with other tools (webservers, EJB containers etc). Its just that
given the volume of traffic I think the things that interest me (and the
things I could mostly helpfully contribute to) are getting lost. Also the
generla configuration issues are typically for the newer users, whilst more
advanced issues (SSL, working with IIS/Apache etc) concern those people who
are more familiar with Tomcat.
By splitting the list, you would reduce traffic for those people only
intersted in one side of it or the other, and those that still care about
both will recieve the same number of posts (bar some potential
cross-posting). This would reduce the amount of people (probably with
something to say) who leave the list because of the amount of daily posts..

List traffic et al

[Sam Newman]

Given the huge amount of traffic this list generates, I can rarely get
involved with the discussions that take place. It occurs to me that there
sems to be three major discussion themes on the list as a whole:

1.) General servlet/jsp development issues and how tomcat affects them
2.) General tomcat configuration issues
3.) Webserver integration issues

I guess as documentation improves (e.g. tomcat book, work by people like
Mike Slinn) points 2&3 will become less of an issue. I'm just wondering if
there is any millage in perhaps splitting the list into 2 or 3 lists?
Personally, I've got no issues with getting tomcat up and running and so
don't care too much about that end of things, however the servlet/jsp
development issues is more interesting to me.

I don't have too strong an opinion on it, its just that I worry I'm missing
some interesting topics because I don't have the time to work though all the
posts

Re: out of environment space

[Sam Newman]

Right, this has nothing to do with tomcat. Windows console applications use
their environment space to store environment variables. Whats happening is
that when you run tomcat, you're filling this space up so some of variables
won't get saved - this could really screw tomcat up. You need to increase
your default environment size. You can do it by creating a shortup to a dos
program and change its properties, but probably the better way to do it is
to add an entry to your config.sys file - can't remember exactly what you
have to do though. Changing config.sys means all console apps will inherit
this value. Try searching microsofts site with the out of environment space
error.

but resin is not free to use if "You get paid to develop with Resin" - this
basically means as far as I can see that for commercial use you'll need to
pay for each server - and it seems to cost around $500 a license.
If its benchmarks are to be believed, I'd certainly look at using it, but

JSP class compilation error

[Sam Newman]

I have a JSP page which has suddenly stopped working. I've found a single
tag which, when included gives the stack trace found at the bottom of the
email. With the tag removed, everything works fine - even when I leave the
other tags in. I have tried this file on Linux & win98. The tag in question
doesn't do anything - the tag handler doAfterBody method simply returns
SKIP_BODY. I'm assuming I must of caused a problem with the XML files
somewhere, but can't for the life of me see where. Anyone get any ideas? I'm
currently using 3.2.1 and so am going to download 3.2.2 and try this version
to see if I can get a better error. I can compile the JSP page under
netbeans using the same libraries with or without the tag being in.

Re: Define the /var/www to serve .jsp ?

[Sam Newman]

When using tomcat and apache, you simply set up a 
new document root and mapping within httpd.conf for each webapp you want 
accessable via Apache. When you run tomcat, it automatically generates the 
Apache directives required to use Apache and Tomcat together uising mod_jk - 
look at the file mod_jk.conf-auto. This file is overwritten whenever tomcat is 
restarted, so don't edit it directly.
For more info check the mod_jk-howto included with 
the tomcat distro.

Re: Tomcat 3.2.2 and Xerces

[Sam Newman]

If it was an inbuilt limitation of Tomcat, I wouldn't expect to see a
ClassDefNotFoundExceptionare you sure you've put your xerces parser .jar
file in the WEB-INF/lib directory of your webapp?
Also Mail Archive does have a search facility for this list. Its pretty crap
but its better than nothing :-)

Re: What are EJB

[Sam Newman]

Hmm...I can certainly send you the config files Orcas uses to work with
Tomcat. I'll try and dig them out (off site at the moment - back next week).
One way to communicate with an EJB container without any config problems at
all, is to use RMI.You bind an RMI object at your EJB container's machine,
which will act as a proxy to the EJB (mine is in fact called
CentralServerProxy). Your servlets then act as an RMI client. All you have
to do to get this to work is run tomcat with a security manager (so you'll
need java 2, and you have to uncomment the relevent line out of your
server.xml), start an RMI security manager before retrieving the reference
to the object, and tailor your tomcat.policy file to allow access (I ended
up granting everything full permissions because I couldn't be bothered to do
it properly :-) ). The beauty of this approach is that:
1.)Tomcat doesn't have to be on the same machine as your EJB container as
the communication is RMI (wouldn't be that secure though). It could even
work over the web (RMI is simply a Java specific layer on Corba).
2.) You abstract the underlying EJB container. Different containers might
require different configuration's for tomcat and the container itself to get
communication to work.
I can go into more detail if you want (I have the code here). It doesn't
take too long to setup, and you can easily protoype the system without an
EJB container behind your Proxy RMI object - you could equally just use JDBC
to connect to MySql or something. Using servlets as an RMI client is
outlines in the Servlet Programming book, in the odds and ends chapter I
think (left my copy at the office!).
Obviously you could use other communication mechanisms to abstract the
communication - we also use 1024 bit encrypted secure pipes to communicate
over the web between out central EJB server and client processes.

Re: What are EJB

[Sam Newman]

Problem is all the containers we've used up till now have had real problems
with bean managed persistance...as a result we had to avoid it. They seem
better now, but its a bit late for us. The single biggest headache I've had
developing/designing EJB's is trying to make the OO centric java (e.g.
encapsulation of data and process) work with the non-OO databases without
sacrificing too many of the advantages of the two (databases speed, Javas
flexibility).
I'm looking forward to the new message beans which are in the new EJB 2.0
spec. Would of made my current project a whole lot easier... Sending
messages/setting state of beans via JMS could be very cool - if it works :-)

Re: What are EJB

[Sam Newman]

The only real similarity between EJB's and normal JavaBeans is that they are
both based on component models. EJB's provide a java representation of some
data in a database - e.g. 1 EJB will equal 1 row in the table, 1 EJB class
is tied to one table. XML is used to tie an EJB and its data to a database.
There is a bit of a problem with this approach, in that a typical OO  design
for such a system can result in a good OO system on the surface, but a real
mess of a database

EJB's need a compliant EJB server, and a database. There are a few free
versions around - try JBoss. They work fine with Servlets/Tomcat given that
they are also part of the j2ee. I personally use Cape Connect (previosly
Orcas) with tomcat without too many problems (there are a couple of class
loader issues in some circumstances however). Orcas actually bundles Tomcat
with it, and they pre-configure it to work with their ejb container.

Re: Formatting Apache+Tomcat Java stack output errors: how?

[Sam Newman]

Well, IIRC the stack outputs simply get sent to Stderr (e.g. when you do
excp.printStackTrace()). You could make stderr point to a different stream
(can do it via the System object) and then have that output stream do the
formatting. The exception reporting provided by Alphaworks JLog can
certainly do some decent formatting (by-the-by, Jlog is NOT log4j, although
they were both originally written by IBM). If you decide to use JLog, please
check the license - it may still be under one of IBM's dodgy ones, as it was
last time I looked (e.g. free to use, but if you use it in your code IBM can
ask for your source code. And believe me, they've done it in the past!).
Personally, I found JLog a little easier to use that Log4j (if less powerful
in some regards), and would still be using it now if not for the shitty
license :-(

Re: Logging

[Sam Newman]

Tomcat 4 supports filters, which may do exactly what you want. They are
defined on the 2.3 spec IIRC. Basically, its a bit of code that gets
accessed before the requested page. There was an article about the use of
filters i think either on javaworld or servlets.com. Assuming you want a 3.2
anwser, then you could direct all traffic through a servlet (or several)
which does the logging, and then have that servlet forward on to the
original page, e.g.:

http://myserver.com/LogAccess?page=userpage.jsp

Would log access from the client, and forward the user to userpage.jsp. Of
course, you could equally develop some tags to automatically log the
request.

Tomcat 3.2.2 vs 3.2.1

[Sam Newman]

I just wondered on the benifits of using tomcat 
3.2.2 over 3.2.1? I know that 3.2.2 is in beta right now, but what advantages 
does it give over 3.2.1? Does it simply contain bug fixes (I'm assuming its 
still the 2.2 spec)?

Re: Adding modules(DSO)

[Sam Newman]

Title: RE: Adding modules



You can only make an Apache moudle a DSO 
module  by building it that way. But I thinkk that most if not all 
pre-built modules are built as DSO anyway? Apache itself needs to be build for 
DSO support. Assuming this is the case simply put the lines:
 
LoadModule libexec/module.so
AddModule module.c
 
After any other LoadModule directuves in your 
httpd.conf file. If your apache is already a DSO one, you'll probably see many 
similar LoadModule examples.

Re: Adding modules

[Sam Newman]

The module your trying to load is a module created to enhance the
capabilities of the Apache webserver. That is, the module is specific to
Apache. Tomcat is really only designed to serve .jsp and servlets although
it can also serve static content. For tomcat to be able to use Apache
modules would make it basically Apache - which is why mod_jk exists to allow
you to use tomcat and apache together to get the capabilities of both.

Re: Problem at mod_jk.conf-auto

[Sam Newman]

Unfortunatley you cannot change this file. It would 
be nice if the contents of this file were based partyl on some meta file so you 
could change stuff like this, or for example which prootocl to use for the 
apache/tomcat connection.
If you want to change this file just paste its 
contents into your httpd.conf. I'd surround the block with some comments so its 
easy to find again. 
If you create new contexts in tomcat you can then 
paste the new sections from the mod_jk.conf-auto into httpd.conf

You might have problems detecting if you are working over a secure

Re: Tomcat & SSL

[Sam Newman]

The ajpv12 protocol is still used to stop tomcat. As such even if you just
use ajpv13 you should still start the ajpv12 connector to allow easy
restarting of tomcat. I guess that eventually ajpv13 will be capable of
handling a tomcat restart and ajpv12 can be removed completely.

Re: Multiple Unique Instances WITHOUT multiple JVM?

[Sam Newman]

I think there is a simpler solution. Firstly, have one web app. Secondly,
have a database (could even be an encyrpted text file) containing user
information.
When a user logs in. You check him against the database to confirm password
etc. You asertain from this which company he works for and you load those
properties. Each servlet's behaviour would depend on the company the user
works for. e.g.servlet A displays page bob.jsp for company bob, but fred.jsp
for company fred. The company properties would be stored in the session
info.
This relies on some decent authentication and session handling stuff, but
makes your life allot simpler. If you want more specific info on tailoring
the content for specific customers, let me know - its a subject close to my
heart (currently anyway!)

Re: Catch me for writing a 'Never Before' BOOK on Tomcat!!!

[Sam Newman]

What would the scope of the book be? Will it be developing a webapp with jsp
and servlets under tomcat, or will it just be about configuring and setting
up tomcat? In either case, I'd guess given the posts I see day in day out on
this list, these following things are essential:

Tomcat & Apache using mod_jk - covering the ajpv12 & ajpv13 differences, and
why NOT to use JServ
Tomcat with SSL via Apache (perhaps including getting apache to use
mod_ssl?)
Deployment using ANT
Tomcat & IIS

Should of course cover both *nix setups and win32 setups. The first two I
know a fair bit about. I know nothing about the second two.

I would guess the book would have to be targeted at tomcat 4.0 to stand a
chance of being up to date when released.

Re: Mission Impossible: Tomcat + Apache ???

[Sam Newman]

the mod_jk.conf-auto tomcat creates authomatically 
generates the apache directives so apache can see the contexts setup under 
tomcat. Whilst they use different document roots, you can easily make them look 
the same my tweaking the generated directives. The .jsp files & servlets 
have to sit under the tomcat webapps directory for them to get picked up by the 
tomcat classloader. The jsp file actually gets compiled at runtime to a servlet 
before being viewed.

  Yes, I've read the apache-tomcat howto, and followed it's

  When I've put (as a test...) snoop.jsp in the

  Only once I've put it in the c:\jakarta-tomcat\webapps\ROOT

Re: Problem with session tracking

[Sam Newman]

Hmm.
I guess its because your forwarding the context wholesale. I'd guess the
sesion is new within that given context, and because your effectively
recreating the context when you forward in that manner, it still counts as
new. I use sendRedirect  instead and this works fine - what do you loose my
using sendRedirect rather than forwarding?

  Hiya all,
   
  We're trying to migrate from running JSP's and servlets 
  under JWS2.0 to Apache+Tomcat.
  
   
  It seems like the simplest and most basic 
  configuration, yet I could find nowhere a way to make this 
  work!!
   
  
  The same way JWS works, (and Apache-Jserv+GnuJsp) 
  also:
   1) Apache serves all static content.
  2) Tomcat serves servlets/JSP's (through apj12)
  3) They both share the same directory structure. 
  (C:\apache\htdocs) and *.jsp files can be anywhere in that directory tree - 
  not *ONLY* in the /examples dir or /jsp dir (!@!@#???)
   
  Did someone actually made this work? 
  how, exactly ?
   
   
  H E L P !!

Re: Problem with session tracking

[Sam Newman]

There is a difference between the way HttpSessions arew created and handled,
and the Cookie objetc. The cookie object creates a persistant cookie on the
clients machine. The HttpSession is just a memory cookie, and as such is
non-persistant and doesn't sit on disk. Looking at your code,
request.getSession() will return either the current session, or will create
a new one if none exists. I would expect that your servlet is the first one
to create the session. Try accessing another servlet after this one - have
that servlet get the session and see if its new. You could just put a link
to itself on the servlets page. The example servlets include a session
example which does just this.  Basically, there are several ways of tracking
sesions, and to make matters really complicated you can use allot of them at
once. It doesn't actually mean they share the data though :-)
It depends on circumstances and personal tastes as to which one you use.

Re: seems as though a servlet engine would have a little clearer documentation on getting servlets running

[Sam Newman]

Go back to first prinicples. Try accessing the servlet directly via tomcat
rather than worying about apache - try looking at
http://youmachine:8080/yourcontext/servlet/YourServlet
The port 8080 reefres to the port tomcat is running on. With no port
specified, it means you are trying to access via the standard http port of
80, which is where Apache (or some other webserver) is running.
If that works, its an Apache/mod_jk issue. If not, its a web.xml issue. Just
to reassure you, tomcat does work - I wouldn't be at all suprised if it has
the largest user base of all servlet engines currently on the market.
If you find that doesn't work, please post your web.xml so we can have a
look. If not, can you post the directives you use to get Apache running with
mod_jk (probably the mod_jk.conf-auto file generated in tomcat/conf).

Re: SSL detection

[Sam Newman]

I'm not sure if this is different on winNT, as I did it on Linux, and so
these instructions are really for that. All the packages mentioned here i
think also come with win32 instructions. First, get Apache using mod_ssl.
Easiest way to do this is to download openssl 0.9.6a (www.openssl.org), the
latest apache source (www.apache.org) and the mod_ssl source (search
google - can't remember the url - maybe www.modssl.org  ) The mod_ssl
install file then explains how to build all 3 packages and get them running.
Then get Apache serving .jsp and servlets via tomcat using the ajpv13
protocol (look at the Apache-Tomcat howto in the docs). The older ajpv12
protocol has some issues with SSL. The servlets and jsps should work equally
well under https or http, with the exception (perhaps) of URL rewritting
when the client has cookies disabled (search the archive for recent posts
for more info).

As I said, this worked for me on Linux, more specifically under SuSE 7.0.

Re: SSL detection

[Sam Newman]

Many thanks for that. I was looking under get methods in the index so I
missed the isSecure one, d'oh!
Now all I have to do is to try and get the encryption strength.I think I
could do that with some client side java script though.

SSL detection

[Sam Newman]

I have Apache and Tomcat running together under SSL. I now want to create a
page which only run under SSL. I want http and https to share the same
documents however. My first idea is to simply have a tag handler, which
detects the protocol, and if not SSL is simply redirects to a page explaning
why they cannot view the requested document.
By problem is that I'm not sure on the correct way to retrieve what type of
protocol is being used. There is a getAuthType method in HttpServletRequest,
but the return type is simply a string (e.g. "BASIC" or "SSL"). My concern
is that this return could vary from browser to browser. Can I assume that if
using SSL the return will always be the string "SSL"? Also, how can I detect
which level of encryption is being used? Ideally, I'd like to restrict users
to connecting using 128bit only, or at least issue a warning when its at
40bit.

Thanks in advance,

Sam

Re: Tomcat vs JServ

[Sam Newman]

I guess it comes down to if it aint broke, don't fix it. If your happy with
the old 2.0 spec, and the fact your unlikely to get much support if things
do go wrong, I guess there isn't much reason to change.
At the end of the day, tomcat is more uptodate than JServ, and using mod_jk
is easier to integrate with Apache.

Re: Serialization problem between JVM 1.1.6 and 1.3

[Sam Newman]

Serialization is only really meant for short term storage, e.g. for
transmition over the network or between java pcoesses via RMI. Its possible
that the class youe serializing contains classes whose implementation is
based partly on native code, which may of changed between the two JVM's.The
only solution I guess is try load the file in a jdk1.1.6 program, export it
to some independant format (XML, CSV file) and then load it with a 1.3
program. I've spent the last month or so removing the use of serialization
from our code as it causes too many problems. Instead we've replaced it with
XML. Jdk 1.4 will include a mechanism for serializing using XML.

Re: Tomcat vs JServ

[Sam Newman]

I'm not sure which "issues" you 
mean
I think that fact that JServ has been in bug fixing 
for a while now is more down to the fact that no more development is being done 
with it. Tomcat supports the latest standards and works fine with Apache via 
mod_jk. And its being actively developed. I for one would be eager to see more 
empahasis being placed on using mod_jk and apache rather than 
JServ.

Re: Cleaning up servlets

[Sam Newman]

Well, the servlet will get destroyed when the servelet is garbage collected
I think. The JVM has a garbage collection thread which starts up
automatically, and its its job to  cleanup unused objects. I'm not sure if
this behaviour changes in tomcat. You can explicitly call the garbage
collector by calling System.gc(),or something similar.
Note that something will only be garbage collected when nothing holds any
references to it (an  oversimplification I know). If you simply want to free
some resources up after a servlet is used, do this in your doPost/doGet
methods.

Re: newbie

[Sam Newman]

Let me guess, these servlets are using sessions? When a session is first
used, there is alarge lag whilst tomcat generates a list of large primes (I
assume) to maintain unique sesion identifiers.
This will happen once and once only, when the first session is accessed
after tomcat starts. Afterwards session access for everyone will see no
delay. It would be nice if you could get tomcat to do this at startup

You kight want to get some decent example code,then edit that to get you

unpacking under tomcat. You can then just edit/view thier simple examples to

Re: WML and JSP

[Sam Newman]

Its possible, but not trivial. It will inevitably 
result in the use of some kind of MVC setup. I would guess the quickest way to 
go would be to abstract the business login into taglibs (e.g. most of the Java 
code in the jsp pages). Then code 2 different jsp files - one for WML, and one 
for HTML, both using the same taglib, just displaying the information in a 
different way. You could then get a servlet to handle the request and direct the 
user to the correct .jsp file.
The O'Reilly Java Server Pages book has a good 
chapter on taglibs & MVC stuff. It also touches on the use of JSP and XML 
specifically for WML, although I preferer the use of taglibs to their proposed 
method.

Re: setting up tomcat and apache to run together

[Sam Newman]

The document you want to consult is the 
Tomcat-Apache howto which should be under the tomcat/doc directory of the tomcat 
install. Basically you end up including a file generated by tomcat in your 
apache's httpd.conf, and sticking mod)jk.so where apache can load it from (e.g. 
libexec). The online version of this doc is at:
 
http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/tomcat-apache-howto.html
 
Although your best of going straight 
to:
 
http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/mod_jk-howto.html
 
as the Tomcat-Apache how-to confuses things by 
saying "Don't use Jserv. Heres how you use Jserv"

I suspect that the servlet is trying to open aoscket or something to talk to

Re: How to read property files?

You'll want to use getResource when your in a jar file. I've found the
safest way is just to know where the property file will be in relation to
the class loading it, and get the URL resource for the class itself. This
URL will differ for a class in a jar, but its still doable.

I suspect getResourceAsStream can only locate property files in your

Re: Servlet jar files

[Sam Newman]

Title: RE: Servlet jar files



You mean that you deploy servlets on customers 
machines? I'm not sure how easy it is to access files outside of the WAR file. I 
suspect you'd have to edit the tomcat.policy file to relax the security sandbox 
that servlets run it. Byd efault I don't think you can access anything outside 
the servlets web context. Alternatively you could deply the webapp unpacked 
(e.g. not use the WAR file). As far as I can see the only benifits of using a 
.WAR file is it looks a little neater, hides some of the internals and makes 
deployment a little easier.

The workers.properties file configures the worker threads that take requests
for servlets/jsp's from apache and processes them appropirately. As such,
when running Tomcat without Apache it will have no effect. You only need to
edit this file when you run Apache and Tomcat together. Infact you'll get a
syntax error on a non-PC platform if you forget to edit this file and try
and include it in the Apache directives. See the workers.properties howto
for more information (its in the Tomcat docs somewhere).

Just to clarify, are you using jserv or mod_jk? And if you are using mod_jk,
are you using the ajpv13 protocl for connection? I'm using mod_jk and
ajpv13, and am session tracking using the HttpSesession class and it works

Allot of people have issues with the documentation for this area. All the
information is there, it just can be a little hard to find :-) The
workers.properties file also perhaps could be a little more intellegent
about file locations et al.

Glad to hear you got it working. As for creating your own webapp area, just
editing the server.xml should be enough. The autogenerated mod_jk.conf_auto
generated by tomcat when it starts will contain the directives apache needs
to recognise your new context. Let us know if you have any more problems
with it.

Re: IE problem or tomcat bug?

[Sam Newman]

We've seen the same version of MS products working very differently on
different OS's. Because allot of the abilities of win32 programs are
fullfilled by the inderlying win32 API's, ther're often subject to change
between different operating systems due to slightly different underlying
API's

The only way I could see the client causing a problem is byscrewing up the
request somehow, and it isn't being properly handled. You might want to
check the Apache logs and well as the tomcat logs. See if there are any
strange messages in access.log for example. I take it the problem context
hash debuing turned on? I would still suggest droping the mod_jk developers
a line, at least they can add it to thier bug database.

Re: IE problem or tomcat bug?

I've not seen this before. You might want to try contacting the developers
of mod_jk (I take it your using this if your using ajpv13?) directly. Its
always a pain when you can't reproduce these kind of problems. Are all of
the problems based around the same version of IE? Which browser do you
yourself use?

Re: Very Basic question about Apache-Tomcat configuration

[Sam Newman]

If you access file://localhost:8080/examples you are completely
circumventing Apache and going straight to tomcat. Assuming this is not what
your doing to get the jsp's to work, I'd hazard a guess that your web
context defined in server.xml under tomcat isn't correctly set. I would
suggest you try temporarily removing the use of JServ, and instead look at
using mod_jk. Tomcat automatically creates a configuration file for
inclusion in httpd.conf which configires apache to use Tomcat in line with
the server.xml file. As a minimum on a clean tomcat install, this will
automatically let you access the example servlets via apache with the
minimum effort. I take it you have consulted the Apache-tomcat howto?

Re: TOMCAT 3.2.1 and mod_jserv for FreeBSD

[Sam Newman]

I'm skipping the jserv build issues - not sure this is the place for
problems with it. JServ was the old method for serving servlets via Apache.
It has been superceded by mod_jk which is much easier to setup and use. the
mod_jk.so is for mod_jk, the mod_jserv.so file is for mod_jserv. For a
comparison of mod_jk and mod_jserv have a look at the Apache-tomcat & mod_jk
howto's.

It can (see the Apache-tomcat readme in the tomcat distro), but it is
strongly suggested that you use mod_jk & tomcat instead of using JServ as it

I've done it with servlets. First ly uou need to make sure your using a

Re: Servlet jar files

[Sam Newman]

You should bundle servlets in a .WAR file. This is the same as a jar file.
It contains the WEB-INF directory for your webapp. See the docs for details
on deplolyment. This .WAR file will sit directly in the webapps directory.

Re: Hiding JSPs from Public Access

[Sam Newman]

I would guess you'd want to stick an action in that checks the current
session ID for user authentication info. If its not found, the rest of the
page isn't displayed (e.g. get a TagHandler to skip the rendering of the
rest of the page). Ideally you could do this via a Taglib and stick it at
the top of each page.

Re: Servlet reloading problems

[Sam Newman]

We have the Orcas EJB container, and they bundle tomcat. They seem to of
changed tomcat in some way so the server.xml is actually called tomcat.xml.
I guess from this post they are not the first people to do this. In Orcas's
case, the reason for the change is that they put all the config files in the
same place, and server.xml would look like a generic Orcas config file
rather than a tomcat specific one.

Re: How to read property files?

[Sam Newman]

Could you get the resource URL of the class loading the properties file, and
then strip off the package and class name? e.g. if Im loading bob.properties
from class Bob in package com/fred/, my resource url for the class would be
/usr/tomcat/webapps/mycontext/WEB-INF/classes/com/fred/Bob.class. If I strip
off the package names and the Bob.class I'd get the path to a props file in
the root. You'll have to play around with this if the class is in a jar
file. Likewise, when loading the props file using the string name, remember
to use File.seperator rather than hardcoding a forward slash.

To be honest It seems it works for some people, and not for others. I'd
guess it probably works for certain servlets running under certain browsers
under certain configs. I basically never trust it. Given that tomcat takes
less than a minute to restart I always tend to do this to reload servets.
The only annoying part being the initial time for calculating session ID's.

Re: Where does System.out.println go under Tomcat

[Sam Newman]

I would strongly suggest you don't use System.out 
commands. Depending on how you run tomcat, it can be very easy to loose this 
information. Insteatd use the HttpServletContext log() method for debugging. I 
went as far as to use this for debugging support classes by passing a reference 
of the calling servlet into method calls. doing something like 
'this.getServletContext().log("msg")` in a servlet will stick stuff in the log 
files under tomcat/log. I belive you can also specify different log files for 
each web context.

Re: mod_jk - DEAD END!

[Sam Newman]

Apache seems to identify servlets, b assuming that anything in a servlet
directory is handled by tomcat, so servlets will always appear in a servlet
directory. As for the docs, I'd aggree that given JServ is no longer the
prefered route all references to it should perhaps be moved elsewhere. To be
honest I'd concentrate on the mod_jk howto rather than the Apache-Tomcat
howto - its probably a little less confusing.
Basically, mod_jk and jserv do the same thing, but jserv is old and has some
issues. It also takes more work to get configured. Using mod_jk on its own
is the way to go. As I said, check the mod_jk howto (included in the tomcat
distro under docs).

It sounds then like apache is not correctly serving jsp files then, or else
your trying the wrong URL. I take it the jsp works fine directly with
tomcat? If so, and assuming you are using mod_jk (please say you are!)
simply including the mod_jk.conf-auto generated by tomcat in httpd.conf
should get you started. try the Tomcat-Apahe howto, and the mod_jk howto
included in the tomcat distro

Re: Followup: WAR deployment with JSP's

[Sam Newman]

3rd party libs (e.g. xml parsers etc) should be placed in the WEB-INF/lib
directory. But this is valid jar files, not simple classes. If you have your
own classes, or even other peoples, unpacked and not in a jar form, put them
in WEB-INF/classes (remembering to mirror thier package in the directory
structure under classes).

So if I had a support class call com.mycomp.UserValidator.class, I would put
it in WEB-INF/classes/com/mycomp/. If I had a jar file I use called
validator.jar, it would be in WEB-INF/lib

Hope this helps,

Re: Logging, server.xml and so on

[Sam Newman]

To get stuff into the log, you have to do the following (I'm assuming your
in a servlet at the time!)

this.getServletContext().log("msg");

or

this.getServletContext().log("msg", exception);

Check the API docs for HttpServletContext for more details. As to how you
can tailor this logging to reflect the debug level set for your context (ala
log4j), I don't know. This works a treat in all my stuff anyway.

Re: Asking for an Opionio on Apache & Tomcat or Just Apache

[Sam Newman]

have you edited the Apache directive for the default filex? Search for
index.html or index.htm in httpd.conf and try adding index.jsp. Apache
doesn't automatically look for any file called index - you need to
explicitly tell it what files to load as defaults. If this doesn't work but
typing in the index.jsp explicitly does, I'd guess is a problem with the
ajpv13 connector (or which ever one you are using).
