AW: Tomcat refusing jsessionid's

[Ralph Einfeldt]

The syntax for the session id is wrong.

Since Servlet Spec 2.2 the session id is not a part of the query 
string but part of the url.
http://www.reseller.com:10001/anacreon/servlet/CustomerIndexServlet;jses
sionid=A4A0314540585318A4F5E327F1457375

You should better disable cookies and use response.encodeUrl().

how to enable -deprecation for jasper with Apache Tomcat/4.0.4-b3

[Claudio Eichenberger]

Hi

For jsp page compilation, I'd like to enable Jasper's compile flag '-deprecation'.

I suppose that a parameter needs to be added to the $CATALINA_BASE/conf/web.xml file 
in the beneath block

  
jsp
org.apache.jasper.servlet.JspServlet
  
logVerbosityLevel
WARNING
  
2
  

but I couldn't get it running.

Many thanks for your help

Claudio

Re: tomcat 2nd instance stopping when i log out - on Solaris.

[Tino Dai]

Have you try nohup'ing the process? That might work (don't have a
solaris box to test that on).

PROPOSAL for Connectors

[thorsten frank]

hi to all,

since there seems to be a fairly wide need for Connectors between tomcat, 
apache, IIS and other webservers, and since jakarta seems to be unable to 
provide binary builds of the connectors for their newest products, let's 
help them out:

anybody that's got a WORKING build of mod_jk / mod_jk2 or mod_webapp 
against apache 2.0.36 on ANY platform, send me an email with that attached. 
please supply the following information:

- server versions (tomcat/apache/...)
- operating system
- compiler for the native build

i'll collect them and hand them to jakarta, to finally get rid of the daily 
'how to get tomcat and apache working' thread in this mailing list.

thanks to anybody that's helping,

Re: Tomcat newbie: multiuser installation

[Phillip Morelock]

I don't know about the "~" stuff but I do know the probable reason you have
to be root to do what you're doing:

To bind to a port < 1024 on linux you must be root.  If you've bound tomcat
to a port lower than 1024, you'll have to be root to start it.

As far as being able to load new classes, have you tried using reloadable
contexts?  search google for

tomcat 4 reloadable contexts


hit "i'm feeling lucky" or just search to find more results.

How To: Setting up Virtual Folders

[Nicholas Orr]

Hi,

I want to set up a virtual folder how do I do it?
I want it to point to "c:\".

This is a dev server so there is no need to say you shouldn't do that as it
is not connected to the internet, it is just so I can use Tomcat with Namo
Web Editor 5.

Btw, I'm using Tomcat 4.0.3

What do you guys think of DBCP? Any specific comments on performance or 
functionality? Do you think it's ready for a "production" project? Should 
I use it over DbConnectionBroker (obviously not a JNDI solution, but it 
works pretty well).

I'd love to hear a review from someone who's been using DBCP.

Tomcat newbie: multiuser installation

[Neil Zanella]

Hello,

I have asked posted question before but got no responses
so I will try this again:

I have installed Tomcat 4.0.3 on Red Hat Linux 7.3 with
Sun JDK 1.4 and J2EE 1.3.1 and everything runs smoothly
but every time I recompile a servlet placed under the
/usr/local/jakarta-tomcat-4.0.3/webapps/ROOT/WEB-INF/classes/
directory I have to restart the Tomcat server as root
in order for the changes to take effect. I need to
set up Tomcat in such a way that each user can restart
the server since no user is supposed to know the root
passwod. In addition, each user should be able to keep
their own servlets under their ~/public_html directory
since each user can only write under ~ and /tmp. Also,
they should able to have a URL involving ~username
point to their servlets.

All I am asking is, how do I configure Tomcat for use
by multiple nonpriviledged servlet developers on a
multiuser Unix like system?

Thanks,

Neil

At least, I'm getting notifications of childern segfaulting in the error
log, the webapp keeps restarting based on the initialization output, and
submitting a request to Apache that is handled through the webapp yields
a pre-mature disconnect.

I'm assuming it is segfaulting when attempting to serv a request.

The question is why. The only misconfiguration I can think of is that I
have not defined any application by name in the server.xml configuration
file. I've added a directory to webapps/ and specified the name of that
directory as the application name in httpd.conf.

Besides the load/addmodule stuff, this is that's in httpd.conf:

   WebAppConnection myWarp warp localhost:8003
   WebAppDeploy myApp myWarp /

Tomcat is configured to listen to 8003 and I've verified it does
(connecting with telnet yields junk - I'm assuming that is the Warp
protocol).

But again, I have done nothing to define any application called "myApp"
besides creating the directory. I'm not sure if this is enough. But even
if it isn't, I doubt a segmentation fault is the intended result.

The system is a Debian "unstable:ish" with Apache 1.3; Tomcat 4.0.3. I
can provide any other info that may be needed upon request.

As for the apache error log, firstly they are flooded with:

   JFC: wam_match request 0001

When making the first request, I get:


[Sun May 26 22:19:32 2002] [notice] child pid 13620 exit signal
Segmentation fault (11)
[Sun May 26 22:19:32 2002] [notice] child pid 13606 exit signal
Segmentation fault (11)
[Sun May 26 22:19:32 2002] [notice] child pid 13605 exit signal
Segmentation fault (11)
[Sun May 26 22:19:32 2002] [notice] child pid 13604 exit signal
Segmentation fault (11)


And then on a subsequent request mod_webapp seems to restart:

*a bunch of benign init data*
[Sun May 26 22:19:32 2002] 13689 (pr_warp.c:85) WARP provider started
[Sun May 26 22:19:32 2002] 13689 (wa_main.c:111) WebApp Library started

Any ideas?

Thanks!

[tek1]

in my web.xml file for my webapp, the fully-qualified classname for a 
filter that i'm using was mispelled and unable to be loaded.

however, when starting tomcat, tomcat said that it could find another 
(unrelated) .jar in WEB-INF/lib.

wondering if this is a bug or other reason why tomcat didn't say, "can't 
find filter "?

thank you.

Re: web.xml

[Eric Everman]

The web.xml file is very completely documented in the Sevlet spec - check 
it out at www.java.sun.com.  Also, I'd recommend O'Reilly's _Java Servlet 
Programming_ which should explain everything you need to know.


No reflection involved,

Re: fails!

[Eric Everman]

 From my experience (not looking at the spec):

When you use the jsp:include tag, the page you include must be a real jsp 
page.  That means that the file name must end with .jsp and the page must 
begin with a page directive of java as the page language (though I believe 
that the declaration is officially optional, but recommended).

The include directive will take *anything* and insert it into the source 
before compiling.

Good luck,

Eric Everman

Re: how does tomcat store session objects?

[Phillip Morelock]

All I really meant about getting started with the docs, etc., is that it
might make any source-wading easier.  When I first looked at Tomcat source I
was quite lost, but when I went through all of the available architecture
stuff, I was then able to very easily drill into the source and find answers
to just exactly the type of question you're asking ("is it a hash map or a
hashtable, or some other type of data structure", etc., "Oh, THAT's what
they mean by interceptor...").

As a side note, I have always believed (from available literature) that most
web-app environments (java, asp, php, or otherwise) provide no
synchronization/protection of any kind for "global" object scopes (session,
application, etc.), and that it is assumed that you treat these entities as
entirely thread-unsafe, unless you serialize your own behavior.  Of course,
I could be wrong, but that's the impression I have always gotten across all
the environments I've worked in (which isn't everything under the sun, but
it's plenty of stuff).  That's also why it's generally a good idea to
absolutely minimize the amount of stuff jammed into a session or application
scope...gives you less "undefined" behavior to debug.  Sounds like you are
already familiar with all this, though.

cheers and good luck

Then you donæt want WARP, at this time. WARP, realised through mod_webapp for 
Apache, doesn't support separating static and dynamic content of a web 
application context. That was supported in mod_jk. You migh want to try building 
mod_jk2 for Apache2. One word of caution, use the latest Apache release, 2.0.36. 
I couldn't get mod_webapp to work on 2.0.35, some threading issues.

Nix.

Hi,

Maybe I just feel like getting someone else's opinion. Because, where
reading the src is excellent excercise, you may not find what the
general policies are regarding any particular feature.   What you will
get is a precise picture of what the product does at that specific point
in time(or for that specific version). I am trying to establish the
broad policies of a  servlet engine implementation - the reference
implementation. If one was going to produce a document which introduced
the product's features I would expect to find this kind of information
in it. So if the servlet spec is a bit vague perhaps the document might
mention a few implementation details. Not an all-out volume of commentry
- just the general approach taken.

Seeing as tomcat has undergone a fair bit of development and has been
subjected to some structural changes between recent releases(i.e. 3.x vs
4.0), I thought my first port of call might be to find a long suffering
fellow tomcat-user who may have passed on a few helpful hints or his/her
take on the big picture (or part thereof, even) - just because he can.

Can someone point me to a reference / tech article or discussion? Does
anyone know whether or not the way the session management is handled by
tomcat has changed in any major way? Are there any caveats to accessing
session objects from multiple simultaneous requests? The way this is
implementated in the reference implementation (between specs) I would
have thought would be documented somewhere other than in the src code.

Regards
Joe

yes I briefly looked at it but didn't on the initial parse find anything 
on session management. From what I can gather, there is no 
synchronization provided by tomcat when it comes to accessing sessions 
or session contents. Maybe accessing sessions is a bit of a red herring 
since we are talking about concurrent access within a single session. 
Whichever data structure tc uses for storing the session objects (or 
facades) would probably answer that one. Hastable is synced while 
HashMap anf the others are not.

thanks for your input fillup!

On the TC 3 documentation page there is an excellent "tomcat internals"

Hi

could someone briefly explain to me how the web.xml
parsing is done.

i am particularly interested in servlet and its
mapping elements

Also how are they stored and how are the objects
generated out of those.

Is it all reflection ???

Help.  In Tomcat 4.0.3

The statement like this:
<%@ include file="rmenu.html" %>
works, but
  

does not.

Any idea what's wrong ? The statement seem to comply with the JSP spec (JSP 
1.1 ?)

[Newbie]: Problem getting started with Tomcat

[Holger Hoffmann]

Hi all!

I'm having some problems getting Tomcat up and running correctly.
The problem is the following:
When running startup.bat (I'm using a WinXP box, the IBM JVM and the latest
Apache) I get the Message:
<-- snip -->
Starting service Tomcat-Standalone
Apache Tomcat/4.0.4-b3
Error unable to create jar cache in /tmp directory :
java.util.zip.ZipException:
 error in opening zip file
Error unable to create jar cache in /tmp directory :
java.util.zip.ZipException:
 error in opening zip file
Starting service Tomcat-Apache
Apache Tomcat/4.0.4-b3
<-- snip -->

When I want to start the Tomcat service it is started and immediately
halted.
When manually starting Tomcat seems to be working since I'm getting the
Tomcat page when opening http://localhost:8080/.

What I tried so far was creating a /tmp folder in %catalina_home% (there's a
/temp folder there), and I tried setting the system variable catalina_home
to my install path. (I even tried setting the catalina_tmp variable, no
effect).

Anyway, would greatly appreciate any help I could get!
TIA
Holger

You probably only downloaded the source, try a nightly build

And could you keep your mails to the list instead of direct? That way (a)
someone else might answer first and (b) the answer will end up in the mail

Jasper JSPC packages

[Luis Reis]

Hi,

I'm trying to use Jasper's JSPC to precompile my JSPs, but, instead of
getting a package for each directory in my docroot - which is what
Jasper does on Tomcat 4 - , I get a package with all the JSPs inside it.
It's easy to see that if you have an index.jsp file in each directory
they will all collide in the same place.

I'm using ant to call JSPC.

Any suggestions ?

Thanks in advance,
LR

Can someone tell me how tomcat stores session objects or at least where
I could find out this info without looking at the src?

Thanks for that, Phillip.

I have downloaded the src-dist for both 3 and 4 versions but have not 
yet genned the javadoc - I'll do that when I've looked at the catalina 
docs. I was hoping there may be docs prior to tc4 (we are currently on 
3.3) but that is a big help nevertheless. I guess its likely I'll find 
out soon the extent of the rewrite.

Cheers
Joe

Try KavaChart from VW. See www.ve.com. It provides nice features generating
charts through servlets, applets or in Swing Java Programs. No Royalties.
