Objects using thread on Start/Stop of Tomcat

[Namasivayam, Sudhakar (Cognizant)]

hi all,
I have a Thread mgr which will create a thread. No if i Start and Stop the 
Tomcat, The older mgr object seems to be still in the JVM and this causes a problem 
because a new mgr is created and i have two copies of threads running simultaneously.. 
  Can any one tell me whether all objects will be destroyed if i do start and stop 
of tomcat? Should i do anything in the  Context Destroyed method od context listener?  
The older object is null in the context destroyed but the thread seems to be alive?

Configuration : Linux + tomcat 4.0.4 + JDK 1.4


thanks in advance

RE: Tomcat returning absolute http:// URL behind SSL Proxy instead of keeping https://

[Benjamin Armintor]

If you're using the JK connector, you can configure this with the scheme attribute of 
the connector in your server.xml.  If you're using an HTTP connector, you're in a bit 
of a bind, as far as I know.  When we did this, I cloned and modified the 
CoyoteConnector class to support a proxyScheme attribute.  It worked, but the other 
implications of the http proxy were enough to get us to run AJP/JK.  Now, if only 
someone would write an NSAPI module for JK2...

Subject:Tomcat returning absolute http:// URL behind SSL Proxy instead of

Hi,
We have the classic 3 tiered webapp architecture with BigIP
loadbalancers acting as SSL Proxies - such that requests for the webapp:
 
https://server/jkmount/
 
1)   Come into the BigIP - the BigIP Proxies the HTTPS and sends the
same request to the Apache servers on port 80
2)   Apache sees the URI with a matching jkmount and sends the
request to the Tomcat worker
3)   PROBLEM: tomcat constructs the absolute URL to return based on
the assumption its port 80 and returns the insecure
http://server/jkmount/index.jsp
 
Found some relevant docs here:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/proxy-howto.html
 
But its unclear how to get tomcat to keep the https:// instead of
returning the absolute http://

I forget the URL, so search the archives and/or Tomcat docs for
"CATALINA_BASE"... There's a doc on doing just this. YMMV but it's
been nothing but wonderful for me. ;)


: How many resources (CPU/memory) does each Tomcat instace require 
: approximately?

As much as they need (CPU) and are given (mem).

You can (sort of) cap the mem by setting JVM heap sizes with -Xmx etc.
I believe the default max heap size is 64m (?128m?).

CPU is a little tougher to restrict.  It's more a game of "spot the
resource hog" and then "use the profiler."

I've found "top" and "ps" great at pinpointing the hogs in large-scale
environments. ;)

Subject: Apache http / mod_rewrite / mod_jk


All,
The archives show this questions being asked all the time, but with no 
useful responses. Please let me know if this is a known unresolved or 
unresolvable issue.

All solutions posted anywhere for "jsessionid makes Apache go beaindead" 
apparently use a mod_rewrite incantation similar to the following:

   
   RewriteEngine on
   # Force URLs with a jsessionid to go to Tomcat. Necessary because
   # Apache doesn't recognise that the semi-colon is special.
   RewriteRule   ^(/.*;jsessionid=.*)$   $1 [T=jserv-servlet]
   

While I'm sure this worked out great the people using mod_jserv back in 
1997, it does not work for mod_jk. For one thing, it does not even let 
you specify which worker to use :(

Back in the day, Craig responded by pointing to a Tomcat FAQ entry which 
no longer exists, but presumably had something to do with Apache's 
mod_rewrite.

On the other hand, a solution was posted (and confirmed by some readers) 
that the following works:

JkMount /test/*;jsessionid=* ajp13

This seems very obvious, and there's a caveat about how it might not 
work on "older" versions of mod_jk. It apparently does not work for me. 
I'm using mod_jk (not mod_jk2), version 1.2.5 (current release) on 
Apache 2.0.48 as a dynamic module on Linux -- everything compiled myself 
with nothing out of the ordinary.

Can anyone offer any advice? I've just been sucking it up and ignoring 
this problem for a while, now (years). Is there actually a solution out 
there for this? Am I just mistyping the JkMount configuration?

Anyone, please help.

Thanks,

RE: Tomcat 5 out of memory

[Angelov, Rossen]

That sounds like a reasonable explanation.

Then, the only solution I can see is to set the development environment not
a virtual server per developer but a Tomcat instance per person and if the
OutOfMemory error happens again, restarting that Tomcat instance won't
interfere with the rest of the developers' work.

Do you by any chance have a link to that discussion you mentioned?
I searched the archive and found some opinions, the closest was this one
"...common classloader repositories (as well as shared and server) do not
get discarded on webapp reload.  They can't, as that might destroy other
webapps."

This probably raises the question in what cases the reload should be used.

Thanks,
Ross

Ross,

If my memory serves me right (which is rarely) there was a discussion on the

references to objects that don't get released when a context is undeployed.
The memory is lost until a restart. In production this should not be an

Try using the IP. If you can get to it with an IP then your issue is with

dedicated Tomcat instances

[wsedio]

Hi,
I've an hosting server running Red Hat Enterprise Linux 3 ES. and I am 
planning to install Tomcat 4.1.x on it, I am pretty new to Tomcat.

I would like to give dedicated Tomcat instances to some clients.
That way, if an instance crashes, the problem shouldn't affect other 
clients web sites.

The dedicated Tomcat instances should also improve security, by keeping 
each customer's applications separated from others clients.

What is the best way to give dedicated Tomcat instances and accomplish 
the above aims?

How many resources (CPU/memory) does each Tomcat instace require 
approximately?

Thanks!

Hi.

Can you post the relevant parts of your httpd.conf file?  Also, I missed
this in the thread if it was mentioned, but what version of Apache are
you working with?  I ask, because it looks like from my setup that
Apache ditched the AddModule directive in Apache 2.0.xx.

LoadModule needs to be in your httpd.conf file before the AddModule
directive under Apache 1.3.x as in:

# All the other LoadModule directive here.
LoadModule jk_module  modules/mod_jk.so

# Further down, all the AddModule directives here
AddModule mod_jk.c

It'd be helpful to see the JkWorkersFile directive, JkMount directive,
and the contents of the jk workers file.

--David

Just tack it on to the end of the list of LoadModule directives.  Then
use AddModule at the end of the list of AddModule directives.

RE: Tomcat 5 out of memory

[Angelov, Rossen]

I don't understand why rebuilding the cache would take more memory than what
was originally required. It just doesn't sound right or it is a memory leak
when you use the stop/start or reload options.

Giving a higher priority to this process is not a very good option because
in our case it is a development UNIX server and there are database and other
peoples' processes running.

Increasing the memory heap size will just slow down the occurrence of that
OutOfMemory error instead of preventing it. I'm actually looking for a long
term solution because it may be critical whether to use tomcat for
production and live web servers.

Thanks,
Ross

rebuilding the cache, I would imagine. I'm not sure how you would reduce
it though, it's "a good thing"(tm) -- really, it's reducing the memory
usage by 2-3MB once the cache is rebuilt. 

This is just an (somewhat) educated guess, though. I suppose you could
give it a higher priority so it could speed it up, and take up more
resources, for a shorter period of time, or alternately, throw some
hardware at it, and add some more memory.

Subject: Cross-site scripting vulnerability
Hi,

Running the Nikto security tool on Tomcat 4.1 produces a warning that
   

it
 

is vulnerable to cross-site scripting attacks.  This is the URL it
   

gives
 

https://:443/666%0a%0aalert('Vulnerable');666.jsp
I edited the the server IP above.  I found a reference to this at

http://archives.neohapsis.com/archives/vuln-dev/2002-q3/0482.html

but no solution was provided.  Does anybody know anything more about
this, especially how to fix it?
I am using Tomcat 4.1.24

   

 

Thanks, I downloaded it and indeed it does work.  Can anyone tell me 
what was done to fix it (ie. can you point me to a bug tracking 
number).  I couldn't find one when I looked on Jakarta's bug database, 
but maybe I was looking in the wrong place or using the wrong search term.

Rui.

Inter Servlet Communication

[Gareth Western]

Hi,
Can someone fill me in as to what I need to do to make objects that are instanstiated in one servlet available to another servlet? I tried using  getServletContext().setAttribute("some.name", myObj) however I was unable to retrieve the object in the other servlet. 

I notice there are some 'public' ServletContext attributes such as

org.apache.catalina.jsp_classpath
javax.servlet.context.tempdir
org.apache.catalina.resources
org.apache.catalina.WELCOME_FILES
So where/how does Tomcat define these?

Even just general help on dealing with context is appreciated. Many thanks for any and all help,

~Gareth

PS Running Tomcat 5.0.18. If any other particulars would help then let me know. Thanks!

Re: Tomcat 5 out of memory

[Nicholas Bernstein]

rebuilding the cache, I would imagine. I'm not sure how you would reduce
it though, it's "a good thing"(tm) -- really, it's reducing the memory
usage by 2-3MB once the cache is rebuilt. 

This is just an (somewhat) educated guess, though. I suppose you could
give it a higher priority so it could speed it up, and take up more
resources, for a shorter period of time, or alternately, throw some
hardware at it, and add some more memory.

Tomcat 5 out of memory

[Angelov, Rossen]

Hi,

We are having problems with Tomcat when restarting the virtual servers or
the contexts - the memory usage goes up with about 2-3 MB per restart.
We have the following java options when starting Catalina:
-Xms128m -Xmx256m -verbose:gc

Does anybody know what's causing such a behavior and how it can be limited?

Thanks,

Tomcat (4.1) doesn't answer

[Gianni Pucciani]

Hi all,
I've installed Tomcat 4.1 and it runs well when I browse 
http://localhost:8080.
With my firewall port open, when I call http://myhost.mydomain.com:8080 
I receive connection refused. I use a dinamic dns, that run correctly. 
When scan my 8080 port with a port scanning (grc.com) the port is open.
Could anyone give me some advice?
Thanks

Re: Can AccessLogValve Cause Tomcat Performance Hit?

[Tim Funk]

You can try to use ExtendedAccessLogValve. It parses the pattern on 
initialization and uses and array and switch statement to determine what to 
print. (In the hope that it would be faster)

OTOH - the problem could be the writing of log data to disk.

RE: Connecting the HTTP Server and Tomcat

Hi

Currently I use
  catalina.sh start | stop
to control tomcat 4.1.x and 5.0.x running as root.

Can I change it easily to use commons-daemon (running as non-root)?
A lot of command line options are set in catalina.sh. Would I need to do
this manually ?

Getting basic Logging up and running

[Jason Palmatier]

Hi,

   I've been trying to get basic logging up and
running so I can diagnose an SSL connection problem. 
I've searched the archive and google for a full day
and picked up bits and pieces, which I cobbled
together, but still can't seem to get any more output
then the initial startup (i.e. output up to and
including the "INFO: Server startup in xx ms" in
catalina.out) message.  I'm using tomcat 5.0.19 and
running on an iSeries at v5r2.  Here are the changes
I've made so far:

In server.xml I added:
- debug="10" wherever debug="0" appears in the file
- verbosityLevel="4" wherever a Logger or Valve tag is
defined
- Otherwise server.xml is just the default with an
HTTPS connector uncommented and spiffed up with
keystore and keypassword attributes.

In catalina.sh (it runs as if on Unix when run on an
iSeries) I added -Djavax.net.debug=ssl to JAVA_OPTS.

Here's what my Global Logger tag looks like in
server.xml:

 


I get a catalina_out..txt file but it only
contains 

2004-04-07 21:23:56 EngineConfig: EngineConfig:
Processing START
2004-04-07 21:43:04 EngineConfig: EngineConfig:
Processing STOP 
2004-04-07 21:46:00 EngineConfig: EngineConfig:
Processing START

I would like to get as much debug information as
possible so I can see the complete initialization of
the Tomcat server and any attempted connects (SSL and
non-SSL).  Ultimately I would like to see detailed SSL
trace, hence the use of the -Djavax.net.debug=ssl
command line option.  I know this shouldn't be very
hard but I can't seem to get the output I want. 
Anyone have an idea what I am doing wrong?

access ENV variables

[Daniel Gibby]

Is it possible to access environment variables in tomcat that were set 
by apache?

Specifically the REDIRECT_ * variables that are set by ErrorDocument 
directives?

Then I can have a servlet return the correct content type.
i.e. if it is a gif that has a 404 I can redirect to a graphic that says 
not found
But if a jsp page is missing or won't compile, I can redirect to a 
different jsp.

Hi.

Can you post the relevant parts of your httpd.conf file?  Also, I missed

this in the thread if it was mentioned, but what version of Apache are 
you working with?  I ask, because it looks like from my setup that 
Apache ditched the AddModule directive in Apache 2.0.xx.

LoadModule needs to be in your httpd.conf file before the AddModule 
directive under Apache 1.3.x as in:

# All the other LoadModule directive here.
LoadModule jk_module  modules/mod_jk.so

Just tack it on to the end of the list of LoadModule directives.  Then 
use AddModule at the end of the list of AddModule directives.

nativeDispatch SEVERE error with apache ErrorDocument on 404 to a servlet

[Daniel Gibby]

Hey all, I just discovered some things that I googled around and 
debugged a bit and couldn't find any help on, so I'm posting it to the 
list so that when I have the problem again, I'll find my own posting via 
google! Maybe it will help someone else as well.

Using: Apache, mod_jk2 tomcat4.1.27
In apache I have ErrorDocument directives that send 404 errors to a servlet.
This was supposed to be setup so that I could forward people who make 
invalid requests to a valid page.
Also I could send errors to a log, and give people a nice looking page 
rather than apache's default.

Here's the tricky part:
I have mod_jk2 setup to forward *.jsp and certain servlets to tomcat, 
but graphics and such come through apache.
If I have a valid request come in to a jsp page or to a servlet... but 
there is a gif/png/jpg missing on that page, then strange things begin 
to happen.
Here's some output:

Normal output complete from jsp page.

Apr 7, 2004 12:53:01 PM org.apache.jk.common.JniHandler nativeDispatch

If you have seen errors such as these in your logs, it may be that you 
are using an apache ErrorDocument forwarding to tomcat, and really you 
just have some missing graphics or other files!

So now that I figured out what is going on... does anyone have an idea 
of how to handle this?
I really want to send just jsp and servlet type 404 errors to a servlet 
/ JSP, not missing graphic 404 errors. But there is no way to 
distinguish them on the apache side that I know of... and no way to 
distinguish them on the tomcat side either.
If you look at some of the apache docs they say that they now set some 
additional CGI variables for this purpose, but I don't think they are 
accessible from jsp.
The variables all start with REDIRECT_
ServletConfig / ServletRequest don't provide a way to get at those 
variables, right? This is kind of going off topic, but help!

Thanks,
Daniel Gibby

RE: request.getUserPrincipal();

[Yansheng Lin]

Hi, how often do you invalidate your sessions?  It's hard to imagine your
application would expire a user's session right after he logs in.  But take a
look at the request header to see if the subsequent session ids are the same as
the first one.  Other than that, without more specific info on how you
implemented the authentication, it's hard to figure out what's going on:).

Hi All,

I am trying to perform client authentication using certificates, and I have
made some progress - the certificates are now accepted as OK, which is nice.
Obviously I am using https too...

However, the sting is that the methods

request.getAuthType();
request.getRemoteUser();
request.getUserPrincipal();

All return NULL, which is contrary to the documentation, since I know the
user (i.e. me) has authenticated. clientAuth="true" in server.xml.

Anyone else out there had this problem, and more to the point found a
solution?

Cheers,

Re: Connecting the HTTP Server and Tomcat

[David Smith]

Hi.

Can you post the relevant parts of your httpd.conf file?  Also, I missed 
this in the thread if it was mentioned, but what version of Apache are 
you working with?  I ask, because it looks like from my setup that 
Apache ditched the AddModule directive in Apache 2.0.xx.

LoadModule needs to be in your httpd.conf file before the AddModule 
directive under Apache 1.3.x as in:

# All the other LoadModule directive here.
LoadModule jk_module  modules/mod_jk.so
# Further down, all the AddModule directives here
AddModule mod_jk.c
It'd be helpful to see the JkWorkersFile directive, JkMount directive, 
and the contents of the jk workers file.

--David

Just tack it on to the end of the list of LoadModule directives.  Then 
use AddModule at the end of the list of AddModule directives.

Is this not what the specification of /portal/* ajp13 in the

Here is a little from one of the pages in that area... (
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/jk/aphowto.html )
In a nutshell a web server is waiting for client HTTP requests. When
these requests arrive the server does whatever is needed to serve the
requests by providing the necessary content. 

Adding a servlet container may somewhat change this behavior. Now the
web server needs also to perform the following: 

Load the servlet container adapter library and initialize it (prior to
serving requests). 
When a request arrives, it needs to check and see if a certain request
belongs to a servlet, if so it needs to let the adapter take the
 

request

   

and handle it. 
The adapter on the other hand needs to know what requests it is going
 

to

   

serve, usually based on some pattern in the request URL, and to where
 

to

   

direct these requests. 

Is this not correct...or am I misunderstanding it

Allen,

do you have the web server configured to throw the requests over to
Tomcat?
In other words, have either Proxy support or else URL Rewriting turned
on in
the web server?
Otherwise your HTTP requests default to port 80, so they will be eaten
by
the web server and never reach Tomcat,
since Tomcat is listening on ports that the HTTP requests do not come

After further testing on my using a JNDI resource in the

But if I link the resource in a Context I can load a JNDI resource in

In both forms of resource linking above the Filter can load the JNDI

Any reasons that there should be a difference in behavior for a

tools.jar & classpath

[Matthias Lindner]

hi everyone,

dumb question time.

here's winXP and tomcat 5.0.19.
after setting up Tomcat as a service it didn't find the tools.jar
and couldn't compile my .jsp's.  the error page told me to copy
tools.jar over from JAVA_HOME/lib/ to TOMCAT_HOME/common/lib and that
works.

but i don't like it.  isn't there a way of telling tomcat or at least
this one context the classpath for tools.jar e.g. via web.xml ?

thanks,
Matthias

Assuming the connector is working, what effect does adding an additional 
mapping of

/portal	ajp13

to your existing

/portal/*	ajp13

mapping have?

I just double-checked on our dev box where jk is definitely up. I got a 
404 from apache for / but //stuff got routed through 
to tomcat.

[Wilson, Allen]

Okay...I've read the article and the way it look is that you are doing
the connection without using a connector like mod_jk. You are doing it
with the proxy module...mod_proxy.so

Is that correct

If so, then it provides me another method to go but before I start back
tracking to do something new..I would like to see if I could get the
mod_jk connector working...

Allen,

you ask "isn't that what the connector is supposed to do",
but the connector is in Tomcat, not in your web server.
It is the web server software that is monitoring port 80,
and that is where your browser sends requests to by default,
so the request must get past the web server first.
To do that you need to tell the web server where to send them, namely to
your Tomcat port.
I think this accounts for the behaviour you told about, namely that
Tomcat responds fine when you specify the port number in your URL.

Howto run tomcat 4.06 as windows service

Hello,

I have an existing tc4 installation (copied in a hurry from
another system ;-) which works fine when launched via the
startup.bat script. Is there a way to turn it into a proper
windows (XP) service? I know tc5 has service.bat, but short
of upgrading, what would be the equivalent here?

Apache http / mod_rewrite / mod_jk

[Christopher Schultz]

All,
The archives show this questions being asked all the time, but with no 
useful responses. Please let me know if this is a known unresolved or 
unresolvable issue.

All solutions posted anywhere for "jsessionid makes Apache go beaindead" 
apparently use a mod_rewrite incantation similar to the following:

  
  RewriteEngine on
  # Force URLs with a jsessionid to go to Tomcat. Necessary because
  # Apache doesn't recognise that the semi-colon is special.
  RewriteRule   ^(/.*;jsessionid=.*)$   $1 [T=jserv-servlet]
  
While I'm sure this worked out great the people using mod_jserv back in 
1997, it does not work for mod_jk. For one thing, it does not even let 
you specify which worker to use :(

Back in the day, Craig responded by pointing to a Tomcat FAQ entry which 
no longer exists, but presumably had something to do with Apache's 
mod_rewrite.

On the other hand, a solution was posted (and confirmed by some readers) 
that the following works:

JkMount /test/*;jsessionid=* ajp13

This seems very obvious, and there's a caveat about how it might not 
work on "older" versions of mod_jk. It apparently does not work for me. 
I'm using mod_jk (not mod_jk2), version 1.2.5 (current release) on 
Apache 2.0.48 as a dynamic module on Linux -- everything compiled myself 
with nothing out of the ordinary.

Can anyone offer any advice? I've just been sucking it up and ignoring 
this problem for a while, now (years). Is there actually a solution out 
there for this? Am I just mistyping the JkMount configuration?

Anyone, please help.

Thanks,
-chris

page through port 8080 it works fine. If I request the same page on
8009


it works fine.

In all cases there were no entries in my mod_jk.log.

I am looking for something that will outline the steps for me on a
Solaris machine or at least give me a better way to diagnose what I am
doing wrong

RE: Connecting the HTTP Server and Tomcat

[Bill Bruns]

Allen,

you ask "isn't that what the connector is supposed to do",
but the connector is in Tomcat, not in your web server.
It is the web server software that is monitoring port 80,
and that is where your browser sends requests to by default,
so the request must get past the web server first.
To do that you need to tell the web server where to send them, namely to
your Tomcat port.
I think this accounts for the behaviour you told about, namely that
Tomcat responds fine when you specify the port number in your URL.

Bill..thanks for the reply...

I will read through the link you provide but isn't that what the
connector is supposed to do.

My understanding what that the Apache HTTP server would detect what the
request was (Java or not) and pass it on to Tomcat.
Is this not what the specification of /portal/* ajp13 in the
configuration does.

This is what I got from the document at:

http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/jk.quickhowto.html

Here is a little from one of the pages in that area... (
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/jk/aphowto.html )

In a nutshell a web server is waiting for client HTTP requests. When
these requests arrive the server does whatever is needed to serve the
requests by providing the necessary content.

Adding a servlet container may somewhat change this behavior. Now the
web server needs also to perform the following:

Load the servlet container adapter library and initialize it (prior to
serving requests).
When a request arrives, it needs to check and see if a certain request
belongs to a servlet, if so it needs to let the adapter take the request
and handle it.
The adapter on the other hand needs to know what requests it is going to
serve, usually based on some pattern in the request URL, and to where to
direct these requests.


Is this not correct...or am I misunderstanding it

Allen,

do you have the web server configured to throw the requests over to
Tomcat?
In other words, have either Proxy support or else URL Rewriting turned
on in
the web server?
Otherwise your HTTP requests default to port 80, so they will be eaten
by
the web server and never reach Tomcat,
since Tomcat is listening on ports that the HTTP requests do not come to

soft linking of directory in tomcat 4.1.27 is not working for me

[Kam Lung Leung]

Hi,

I recently upgraded to tomcat 4.1.27. Some how the soft linking of directory
within my web application directory is no longer accessible from a browser. It
must be configuration issue. Can some please let me know how to configure tomcat
4.1.27 so that it will follow the soft linked directory.

Thank you in advance,

JK2 Load Balancing Algorithms.

[Angus Mezick]

Is the only available JK2 load balancing algorithm a weighted round
robin?  I would like to switch to one that has a primary server and then
switches to round robin to reach the secondary server when an error is
thrown.  The reason I would like to do this is because we have 5 web
servers each with a apache/tomcat pair fronted by a Cisco Local
Director.  I would like the request to stay on the machine that cisco
sent the request to as long as the local tomcat is accepting requests.
I currely have annecdotal evidence that the current weight round robin
approach is a little flakey and is sending WebServer01 more requests
then are the server's fair share.  I wrote a logging filter and some
RequestHeader statements in the http.conf to try to get hard evidence
that this is happening.

Thanks,
--Angus

Can this work?  Other ideas?

session tracking using uri not cookies (was How can I maintain state with Axis

[Paul Mansfield]

With recent discussions about session management, I recalled long time
ago reading about URI rewriting for when the client doesn't handle
cookies properly, and found a useful article about it

http://access1.sun.com/techarticles/sessions.iws.html

"URL rewriting is the ability to use sessions and session information if
cookies have been disallowed or are not available on the client.  URL
rewriting can also be useful when, for example, proxy or firewall
servers change or disallow cookies.  Cookies are small bits of data
stored by the client; for example by a Web browser.  "

OK, this is for sun's iplanet, but the information might still be
relevant to tomcat.

hi tomcat-users

i set up jk2 with apache and tomcat and it works just fine. but now i 
have changed the uri-definitions in workers2.properties. after this i 
restarted apache and tomcat - and nothing changed!

is there any way to explicitly reload the workers2.properties file?

i can remove an entire uri-mapping in the file, restart both apache and 
tomcat - and the removed uri just works fine. like the module uses an

RE: Custom session tracking method?

[Mike Curwen]

So I'd have a servlet mapped to /login.

Protect it with Basic Auth, so that takes care of the Auth, and then
you're passed on to the /login servlet.  This login servlet creates a
new session, and then does one extra step.
It maps in the ServletContext ('application') the custom session-num
you've just created , to the jsessionid.  


your client does not have cookies. It does not have a jsessionid in the
URL either.  So to Tomcat, any subsequent requests would appear to have
no session.  So...

Construct a filter, mapped to '/*' (everything).  In the filter,
retrieve the session-num from the request parameters, lookup the actual
jsessionid from the application context, and then  
This is where it gets fuzzy for me...

1) 'append' the jsessionid as a parameter and doChain() ? (that probably
won't work, jsessionid in the URL is more special than just 'another
parameter').

2) 'rewrite' the URL yourself, placing the jsessionid where it ought to
be
http://www.foo.com/originalURI;jsessionid=56D49A19C332F095C79CABFC621B50
B1.tomcat2?originalParam1=A&originalParam2=B&etc
And then .forwad() this request, but don't doChain().



Is any of that craziness ??

RE: JK2 connector built and installed but is there something wrong?

[Kevin Struckhoff]

OK, well now I know why. I had added an examples
directory and 1 html page under the htdocs dir of my
Apache Webserver. That's because the port number is
8080, not 80. 

Thanks.

Re: Custom session tracking method?

[Sandy McArthur]

The first request the legacy app makes is to /login which it uses your 
normal Basic authentication which is nice because I can use a standard 
Realm. In the response to /login is a session number the client should 
use along with some data about the user's account. Unfortunately the 
session number must fit in a 4 byte integer in the app. :( After that 
the session is passed around via the session-num query param.

From whence does the "session-num" query parameter come?  Does the
legacy client create a random number and use it?  Do the cgi scripts
pass it back on a login of some sort, and then from that point, the
legacy app appends it to any further queries?

Subject: Custom session tracking method?
Hi all,

Is there a way to implement custom session tracking at the
container
level?

I'm trying to figure out how to implement a custom session
tracking
method. I have a legacy client that interacts with a set of cgi
scripts and I'd like to port those scripts to servlets.
I'm running
into a problem because the client passes session ids as a query
parameter named 'session-num' (e.g.:
/update?session-num=TOKEN). The
client does not support cookies and there is no way to
tell it use a
JSESSIONID encoded in the path.

I've followed the code as best as I can starting at
org.apache.coyote.tomcat5.CoyoteAdapter parses the JSESSIONID from
the request/cookies to where the
org.apache.catalina.Manager fetches
the org.apache.catalina.Session and I don't see anyway to directly
override the session tracking behavior.
The best idea I currently have is to use a Valve and a
custom Manager
and hope none of the Manager.{create,find}Session() methods are
called before my Valve can parse the request and stuff the
"session-num" in a ThreadLocal that Manager can use when
returning a
Session.

That feels ugly and fragile to me. Does anyone have a better
solution?

RE: Wrapping Requests and jsp:include

[Mike Curwen]

I only wanted to know if Tomcat wrapped the request object in a façade
of some sort, when it does a jsp:include.
 
Maybe I should have just asked that much simpler question. ;)  (Or
looked at the source of a compiled jsp page?)  But well... there's still
the question of "that's the way Tomcat does it" vs. "this is how Resin
does the same thing" and whether or not there is a spec mandate to do it
one way or another.

What I'm trying (and succeeding) to do is access a multipart upload from
included jsp files. I just want to make sure this same code would work
'everywhere'.

Re: Tomcat and SSL: problem with expiration of VeriSign Global Server ID Intermediate Root

It seems that the only way to solve this problem is to get a new
cert from VeriSign. The german support-team had no problem to give
me a new one for free because they think that the expiration is their
problem, so they do anything to help the customer! To get a new
cert just follow the instructions written down in the tomcat 
documentation (generate key, csr, get csr-response, import response).

Thx again for your replies!

This wouldn't make a difference: if your web.xml is valid, it's valid.
If your web.xml is invalid, you would've gotten an error on startup and

TEI Classloading

[Carl Olivier]

Hi.
 
With regards the TEI classloading issue I mentioned in my previous mail
(Issues on Tomcat5.0.19) - I *think* that the engine reports this error -
but in previous versions of Tomcat the exception was not thrown (bubbled to
the top) - blocking the running of ANY JSP page referencing the taglib in
question.  Maybe in Tomcat 5.0.19 this exception should be caught and logged
but not thrown all the way to the top?
 
Yoav:  To replicate it is easy of course:
 
Create a custom tag-lib - the tld file and some classes for the tags -
however one or more of your tags MUST have a TEI class in the Tag definition
in the TLD file - but the class file this TEI class entry reference must NOT
exist in the classpath.
 
This *should* cause ANY page that includes/reference the tag library to
throw an exception about not being able to find the TEI class - running in
Tomcat 5.0.19.
 
With regards my reasoning - I deployed a site of ours to JBoss (embedding
Tomcat 4.1.29) today - and noticed that the ENGINE component was reporting
the exception about not finding certain TEI classes - however the webapp
deployment worked fine.
 
Now - I know this is not the error I reported in ym last mail - but it is
related I think.  In my mail I mentioned that on the first request to a site
running on Tomcat 5.0.19 after a restart I SOMETIMES (I would say 30% of the
time) get the same exception - except that the TEI class the exception was
being reported on ACTUALLY DOES exist in the webapp's /WEB-INF/classes path.
 
It seems that the classloader has not finished loading (is that possible?)
at the time that tomcat tries to compile the JSP (which involves parsing any
custom taglibs the page references).
 
Unfortunately I have not got an EASY SMALL replication the the instance
where the the class does exists and the exception is thrown - working on it!
 
Any thoughts will be appreciated.

Re: Custom session tracking method?

[Sandy McArthur]

Since you're rewriting your CGI scripts as servlets, why not modify 
them
to not expect the session-num parameter, and instead get the session ID
via normal java code (request.getSession().getId())?  It's simpler,
standard, less code for you to write and test...
My problem is the client, which is a desktop app, doesn't support 
cookies and uses hardcoded URIs for the cgi's. The app is what uses the 
query parameter session-num for session tracking, otherwise I would 
prefer to use the normal session tracking semantics.

Subject: Custom session tracking method?
Hi all,

Is there a way to implement custom session tracking at the container
level?
I'm trying to figure out how to implement a custom session tracking
method. I have a legacy client that interacts with a set of cgi 
scripts
and I'd like to port those scripts to servlets. I'm running into a
problem because the client passes session ids as a query parameter
named 'session-num' (e.g.: /update?session-num=TOKEN). The client does
not support cookies and there is no way to tell it use a JSESSIONID
encoded in the path.

I've followed the code as best as I can starting at
org.apache.coyote.tomcat5.CoyoteAdapter parses the JSESSIONID from the
request/cookies to where the org.apache.catalina.Manager fetches the
org.apache.catalina.Session and I don't see anyway to directly 
override
the session tracking behavior.

The best idea I currently have is to use a Valve and a custom Manager
and hope none of the Manager.{create,find}Session() methods are called
before my Valve can parse the request and stuff the "session-num" in a
ThreadLocal that Manager can use when returning a Session.
That feels ugly and fragile to me. Does anyone have a better solution?

I am not sure what they are but I get them often and they always come in

Me too, though I haven't done it in a while.  What tomcat version are

This wouldn't make a difference: if your web.xml is valid, it's valid.
If your web.xml is invalid, you would've gotten an error on startup and
not gotten this far.

handling page redirects

[Luc Foisy]

I have the following in a jsp file

<%@ include file="applicationimports.inc" %>
<%@ include file="connection.inc" %>
<%@ include file="sessioncheck.inc" %>

<%
CustomerHTTPManagementScreen customerHTTPManagementScreen = 
(CustomerHTTPManagementScreen)session.getAttribute("customerHTTPManagementScreen");
if( customerHTTPManagementScreen == null )
{

response.sendRedirect(tmWebApp.getTMTokenizedPageProcessor().tokenizeLink("main.jsp"));
return;
}
if( request.getParameter("submit") != null )
{
if( request.getParameter("submit").equals("Modify Order") )
{

response.sendRedirect(tmWebApp.getTMTokenizedPageProcessor().tokenizeLink("orderentry.jsp?OpenOrder="
 + customerHTTPManagementScreen.getOrderHeaderID()));
return;
}
String key;
Hashtable parameters = new Hashtable();
for( Enumeration e = request.getParameterNames(); e.hasMoreElements() 
;)
{
key = (String)e.nextElement();
parameters.put(key, request.getParameter(key));
}
customerHTTPManagementScreen.processPerformed( new 
ProcessEvent(request.getParameter("submit"), parameters) );
}

response.sendRedirect(tmWebApp.getTMTokenizedPageProcessor().tokenizeLink("customer.jsp"));
%>

This file handles the processing for its connected jsp page (it is directed here to do 
the processing).
As you can see near the end is calls processPerformed, that sends the submit to the 
parent class. The parent class then does most of the process, then it is redirected 
back to the connected parent jsp (in this case custoner.jsp)
What I want to do here is get the submit of "Modify Order" to be handled by my web 
application. My web application main class is tmWebApp, it already has response and 
request available to it, so I could call the redirect from there.

The problem is, this jsp file will then try to redirect the page again on the last 
call. How do I determine if the application already redirected this?

Is my only option to catch an IllegalStateException or check isCommited()? Not as if 
that is a bad idea, but would there be anything else here that would get in my way, 
like is there anything else that would set that response to be commited?

RE: Where to set JAVA_OPTS

[ldrobertson]

We use the setenv.sh. (tomcat 4.1xxx) for all custom environment variables
as well as java options.  catalina.sh references this script:

# Get standard environment variables
PRGDIR=`dirname "$PRG"`
CATALINA_HOME=`cd "$PRGDIR/.." ; pwd`
if [ -r "$CATALINA_HOME"/bin/setenv.sh ]; then
  . "$CATALINA_HOME"/bin/setenv.sh
fi

catalina.bat has a similar reference.



We create a setenv.sh in the bin directory and place ALL environment
variables in it, including CATALINA_OPTS.  Example contents:

export CATALINA_HOME=/usr/local/tomcat

# jvm command line options for tomcat
export CATALINA_OPTS=-mx128m


# db/2 env
export PATH=$PATH:/home/db2inst1/sqllib/bin
export LIBPATH=$LIBPATH:/home/db2inst1/sqllib/lib
export LD_LIBRARY_PATH=/home/db2inst1/sqllib/lib

RE: Wrapping Requests and jsp:include

I know that works. My main concern was "does tomcat internally construct

But when I put the same init code in the Filter.doFilter(...) method  
such that it only executes once, but delayed until the webapp has been  
made available I have no problems.

I skimmed the servlet 2.4 spec and found nothing stating the  
availability of JNDI resources at the time a filter is instantiated.

I tried reordering my web.xml so that the resource-env-ref came before  
the problematic filter to no avail.

Does this sound like a bug, an ambiguous part of the Servlet spec,  or  
am I missing something?

request.getUserPrincipal();

[Winter, G (Graeme)]

Hi All,

I am trying to perform client authentication using certificates, and I have
made some progress - the certificates are now accepted as OK, which is nice.
Obviously I am using https too...

However, the sting is that the methods

request.getAuthType();
request.getRemoteUser();
request.getUserPrincipal();

All return NULL, which is contrary to the documentation, since I know the
user (i.e. me) has authenticated. clientAuth="true" in server.xml.

Anyone else out there had this problem, and more to the point found a
solution?

Cheers,

Graeme

[OT] how to save a form field to client

[Longley, Andrew]

Hi all,

Not really a Tomcat question but I'm hoping someone has a good
suggestion.  I have a Tomcat app with a chat client talking to a jabber
chat server.  A business requirement is to be able to click a button to
save the chat transcript to the client hard drive.  The only solution
I've come up with so far is basically submitting the text area as an
input to a servlet, that then saves the file to a temporary directory on
the server and redirects the client request to that file, which would
(hopefully) initiate the "save or open" dialog we all know and love.

Can this work?  Other ideas?

Thanks!

This error message is one generated by the javac compiler, and usually indicates that

RE: Can AccessLogValve Cause Tomcat Performance Hit?

[Shapira, Yoav]

Hi,
How can you expect the addition of ANY component to the processing
pipeline NOT to cause a performance hit?  Of course AccessLogValve adds
something, nothing comes for free.  You can control the hit by modifying
what you're logging and disabling DNS lookups, as others have suggested.

Gianni,

From my experience:
User tomcat is created for you.

Place it in whatever directory makes sense to you.(Keep it simple)

Keep the permissions on the tomcat directories tight. Make them only
readable by tomcat etc.
 

Ok, thanks!

RE: JK2 connector built and installed but is there something wrong?

[Mark Nye]

Hi,
  I had a similar problem.  The line for the uri has to have a directory
that is under $TOMCAT_HOME/webapps.  

[uri:/jsp-examples/*] would require the directory
$TOMCAT_HOME/webapps/jsp-examples.  As Drew said you can try
servlets-examples instead of jsp-examples.  Those directories are under the
webapps folder by default.

try doing this

[uri:/jsp-examples/*]
worker=ajp13:localhost:8009

There is no examples structure.  You can also try servlets-examples.

After downloading the source and building it, I
finally have mod_jk2 at least loaded into Apache Web
Server 2.0.48.

However, in the docs, it says to add these 2
directives to workers2.properties:

[uri:/examples/*]
worker=ajp13:localhost:8009

When I send the browser to http://localhost/examples/,
I get a -404 error (not found).

What am I missing? Apache starts up just fine.

TIA.

Thanks.

Kevin

Re: Bad Class Version while compiling JSP Files on Tomcat

[David Smith]

Hi.

Sounds to me like your jar files are compiled under different JDKs.  Be 
sure when you install j2sdk1.4.2 to completely replace all files in the 
JDK directory.  I'd actually go so far as to clean install in a separate 
directory (ie /usr/java/j2sdk1.4.2_04) and then symlink j2sdk to it.  
Set JAVA_HOME to j2sdk and it'll find the jdk.  Also be sure all your 
webapp files are compiled under the 1.4.2 JDK.

I have j2sdk1.4.2. Exact version information as follows.

java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2-b28)
Java HotSpot(TM) Client VM (build 1.4.2-b28, mixed mode)
On Tomcat 4.0-b7, Tomcat 5.0.7 & Tomcat 5.0.19 JSP pages couldn't
compile while servlets works fine. Iknow by shifting to jdk1.3.1 this
problem will solve. But I can not do that. Tomcat 5.0.19 is the latest
release build.
Is the same problem everywhere?

To get rid of this should I download whole source code & other huge
libraries & compile it for j2sdk1.4.2.
Or downloading jikes will solve problem?
