Configutaion Problems NT <=> Linux

[Loïc Lefèvre]

Hi

It's me again... Last time, tomcat was configured perfectly
for NT4. Still I must install it on linux now and after copying
exactly (but directories ;) ) the result is not the one expected:
nothing appears !

Any suggestion?

Re: mod_jk on Solaris 2.6 : undefined symbols

Because with -G ld ignores undefined symbols and when I start
Apache, it complains about that same exact symbol, ie :

[root@mybox /export/home/apache]# bin/apachectl start
Syntax error on line 979 of /usr/local/apache/conf/httpd.conf:

ClassCastException on a bean

[Paul Foxton]

Hi,

I've just had an odd problem I thought I'd see if anyone else had come
accross:
Running tomcat 3.2.2, apache 1.3.19 on RH linux 7.1, I got a
ClassCastException for a bean (called DbUtilities) I use in a JSP page.

The code from the compiled servlet of the jsp is as follows: 

DbUtilities db = null;
boolean _jspx_specialdb = false;
 synchronized(application) {
   db = (DbUtilities)  < this line caused the
ClassCastException
   pageContext.getAttribute("db",pageContext.APPLICATION_SCOPE);
 
Its odd because both the bean and JSP had been working fine for a week or so
& I hadn't modified either.

I restarted tomcat and apache and everything was fine again - just a little
concernred, I don't want this happenning when the site goes live!

Has anyone else seen anything like this?

cheers,

Paul

Re: virtual hosting conf question

[Kaneda K]

I Might be wrong, but in order to allow Apache to communicate with tomcat, 
you need to use ajp13 instead of 12. and did you correctly set mod_jk.so. ?

Re: Configutaion Problems NT <=> Linux

[Jeff Hoare]

What happens?
If this fits your situation then this may help.
If u are using the sun jdk1.3.1 and u are using a 2.4 kernel then one thing 
that can happen is that the jdk won't start because of the default stack 
size. In this case you'll get nothing, the thing will try to start tehn die.

If this sounds like you then try
ulimit  -s 2048

Jeff
PS failing that u really need to provide more info, are any logs produced?

Weird thread/security problem

[Sam Joseph]

Hi,

So I think this is a thread/security issue, but I am not sure.  However
it is definitely weird.

I have been conducting some tests with multiple users.  Various servlets
are contacted that supply pages to each user, that include information
such as user name etc.  The version of tomcat in use is 3.2.1, and
clearly I should upgrade to 3.2.3, but the tomcat is provided by my
service provider so that might take some time.

Anyway, the problem is that sometimes when two users are accessing the
system simulatenously the information for one user will be displayed,
briefly, to the other user.  The system I have developed is quite
complicated so I can't rule out that this is a problem with the code,
but I'm not using static variables or anything that would allow this
swap over.  I mean each user has an object associated with them that
contains their user name, but these are local variables to the servlet.

Are there or have there been problems with tomcat that would explain
this problem?  I mean tomcat creates a separate thread for each servlet
right? Different user, different thread, so their data shouldn't be
available to each other.

Am I overlooking something here?  Should I be mailing to the developer's
list?

And on the same topic, does anyone know of any software that will
simulate multiple users, without me having all my friends test the
system.  I mean some software (ideally free or shareware) that would
simulate the stream of http requests, I guess I could hack something
together myself, but if there's something already out there that would
be great.

Thanks in advance.

RE: Weird thread/security problem

[Michael Weissenbacher]

that is a simple problem of understanding: there is only one servlet object
that is used by multiple threads. by having this in mind, your object
variables are also shared, as would be static variables...

and my VHost is the following:

isapi_redirect.dl

[Furer Alexander]

Hi! I'm useing Tomcat3.2 with 
isapi_redirect.dll. 
Here is part of my server.xml config file: 
 
 

 When i run servlets directly 
(hostname:8080/servle/myservlet) the concurrency is OK, i see that requests 
arrive almost in the same time, but when i run through 
isapi_redirect.dll(hostname/servlet/myservlet), the requests arrive one 
after another. What am i doing wrong ? May be i should specify same 
configurations in some ather places ?
Is isapi_redirect.dll multithreaded 
?
 Thanks

Re: Configutaion Problems NT <=> Linux

[Jeff Hoare]

ok,
so httpd -t will tell u for sure if you have a syntax problem.
I not really familiar with virtual host config, to know if this is correct/ 
or not. 

Is the directory readable by the use that runs the web server?

Should you DocumentRoot stop at webapps? as its seems to be looking for 
webapps/lol/lol ?

Maybe that someone else can assist further.

Thanks for the help here.  Gods, I've been writing various servlet applications
for over a year and it seems I've been working with a fundamental
misconception.

This is what comes from spending too much time by yourself, and more
importantly assuming that single user test results extend to multiple users

I guess I have two options, either make the servlet implement the
SingleThreadModel interface, or create some new classes to encapsulate the
appropriate data, and either store that in the session or in some instance
variable like a hashtable ...

Thanks again.

Re: virtual hosting conf question

[Jerry QU]

it works by using ajp12. what I missed was vhost setting in server.xml. and I did in

Multiple development using tomcat

[Pete]

Hi,

I currently am trying to setup tomcat (3.3) to connect to apache-1.3.20,
using mod_jk (apache isn't compiled with DSO support, but has mod_jk , ssl
and php4 support compiled in) .. I can get tomcat working with it fine (i am
still loading the mod_jk module for the tomcat side) ... However we have a
large userbase (students) , and each one will want there own jsp and servlet
directories for there own independant development.. Going through the
mailing list archive search i found one user that did this per user (which
if fine, i could script something to do that for all my users):

Alias /~userX "/home/userX/www"

Options Indexes FollowSymLinks

ApJServMount /~userX/servlet /~userX

However, i would rather not set the classpath for each individual user..
Also due to the large number of users, i would rather not have to restart
the server all the time (although at worst, i will have to set daily, and
users will just have to live with it).. Is it possible for each user to set
there own classpath etc? Anything else that i need to set to achieve this?

Cheers for help
Pete

tomcat.sh stop = Connection refused?

[Richard Draucker]

When I attempt to shutdown Tomcat with the tomcat.sh script I get: 

java.net.ConnectionException Connection refused

This is new since I started running RH7.1 and Java1.3.1
with Tomcat 3.1. Anyone know why? 

Of course I can kill it just fine.  But, a nice clean stop would be 
preferable. 


Thanks,
Richard

Re: Forbidden error, you are unable to access /examples from this server: please help, very urgent

[David Smith]

Just a thought on this thread and I've been guilty of this one as well, but 
you might also want to check directory and file permissions.  If the user 
apache is running under does not have at least read permissions, the whole 
thing will fail regardless of settings in any .conf file.

Re: Help w/ Tomcat 4.0b6 and Apache

[Mark Dzmura]

Pier:

(I sent this last night, also - but it never seemed to make it too the list.)

SUCCESS!!  But first...

The Java part of the webapp connector does not build for the lack of the
following constant definitions in class org.apache.catalina.connector.warp.Constants:

Constants.TYPE_CBK_DONE
Constants.TYPE_CBK_DATA
Constants.TYPE_CBK_READ

I looked in the C code for corresponding definitions, found them, and added them
to the Java code.  Built and installed the new stuff.  Checked the old example tests,
then went to the app using getParameter() and found them to WORK.  YES!!

Maybe the next thing is to run the JSP test suite...

Thanks for knocking out these fixes so quickly - great job!

Problems with authentication

[Mattias Karlsvaerd]

Hello!

I've have problems with getting the authorization to
work in tomcat 3.2.2 and Apache 1.3.19. I have tried
to the example comes with tomcat. I get the login
page, but when I've typed the username and password I
get the following error:
The requested URL
/examples/jsp/security/login/j_security_check was not
found on this server.

I've searched on the web and found out that other
people have had the same problem. Is there a solution
to this problem.
What I understand j_security_check, j_username and
j_password is some kind of implicit variables. Is
there any document where this specified.

I use linux Redhat 7.1 and IBM's java2 1.3
I would be thankful for any help

Hi all,
I checked my apache htdocs and saw that all files do have the readme
permissions.
My mod_jk.log looks like this,  i think the error lies here.  Please check
and suggest some solutions.

Re: howto redirect

[Bernhard Wraase]

Thank you for your response Rams,

> this is not possible..

but what does this mean?

1.) Redirect won't work at all
or
2) It should work because the server.xml seems to be okay
or
3) It can't work because the server.xml has severe failures
or
4) Something else

Re: Problems with authentication

[Joseph D Toussaint]

It's my understanding that j_security_check, j_username and j_password
are all used with form based authentication (specified in th web.xml).
The idea is that you create a 'custom login screen' and name you user
field j_username and your password j_password.  Then the action for that
form is j_security_check.

Thats about the extent of my knowledge, for more information I'd look at
the Servlet 2.3 spec.  Thats where I found the stuff mentioned above.


hope it helps

root@brazil:~# apachectl restart
/usr/sbin/apachectl restart: httpd restarted

but nothing appear at http://localhost:8007
http://localhost:80 is ok.

this is the end (altered by myself) of /etc/apache/httpd.conf:
---8<-
...
LoadModule jserv_module /usr/lib/apache/1.3/mod_jserv.so

# The following line is for apacheconfig - DO NOT REMOVE!
ApJServLogFile DISABLED
Include /etc/jserv/jserv.conf

 
#tomcat
Include /usr/local/jakarta-tomcat-3.2.3/conf/brazil-tomcat-apache.conf

You can read the "Developing Applications With Tomcat"
it discribes in steps how you could develop a
webapplication with Tomcat and how the directorytree
should look like. It's availible on tomcat's homepage.

The web.xml file should be placed in the WEB-INF dir
in your docbase dir.
You also have to define a context for your application
in server.xml. This file can be found in the tomcat
home dir in the conf dir.

tomcat4b6 classpath for poolman.xml

[Matt Barre]

I am moving a few of my applications from tomcat 3.2 to tomcat4-b6. I have them up and
running except for some trouble with poolman. From the trace before it kills tomcat, it
looks like it can't find the poolman.xml file. With tomcat 3.2 I simply have this file 
in
my jdkhome/jre/lib/ext/ folder. Anyone have a tip for where I should place a copy for
tomcat 4 to access? I'm on win2k with 2.0.4 of poolman.

Thanks,
Matt

Re: locating web.xml

[JBrawner]

Does tomcat require a WEB-INF directory? I would like to replace the
default:
\WEB-INF\classesdirectory with simply:
\servlet
and have my web.xml be in \servlet instead of \WEB-INF\classes

Is this possible?

tomcat on Port 80 through IIS 5 on Win2K

[Curtis Dougherty]

I have a site we have written to use tomcat... call it foosite
we have been accessing it internally as
http://my_site:8080/foosite/index.jsp

I want to set it up on an exposed server...call it foo_net so that from the
big/bad internet we can access it by entering
http://foo_net or even better https://foo_net (ssl - 443)

Can Tomcat support IIS5 as a proxy through port 80 on foo_net or SSL on port
443.  We're using Tomcat 4 Beta6 and I can't find any documentation on how
to do this?

Can someone send me the link or tell what I need to do?  

Thanks in advance.

Tomcat 4.0 b5 does not recognize changes in deployed applications

[[EMAIL PROTECTED]]

Please help me as I have been unable to solve this problem.
I am using tomcat 4.0 beta 5 on Windows 98
Every time I deploy a new application to tomcat i.e make a new folder under
"Tomcat-Home\webapps" it is automatically recognized on a server restart.
But any JSP pages that I subsequently add to the folder are not recognized
by the server even after a server restart.
Similarly if this correctly functioning (initially) application is
duplicated with a different name under "Tomcat-Home\webapps" and the server
is restarted the duplicated application is visible to the server but the
duplicated JSP's don't get compiled and I get the following message "a
servlet exception has occurred"
I would be grateful if someone tells me how the incremental changes to ones
application can be correctly reflected to tomcat.

RE: keeping sessions when switching from http to https

[Li Liang]

It seems that Tomcat treats "http" and "https" as different domains. So
that it can't encode the "http" session id into "https" url. Maybe you
should post this question to Tomcat-dev mailing list if you can't get
the answer here. I am sure the developers must realize this issue since
this is something happening in many cases.

Thanks.

I access a JSP SessionTest.jsp using http. The jsp contains a link which
looks like:

go to new link

Nothing is added to the encoded url, i.e. no url rewriting takes place.

When I access the same JSP page using https to start with, the rewriting
works fine.

I wonder if it has something to do how the virtual servers (the http and
the
https) are set up?

I guess that's the way Tomcat parses the session info from request. When
it gets the cookie, everything is fine that it can get "jsessionid" from
the cookie and passes it back.

But without cookie, it needs to rewrite the url. I saw somebody said
that "https" and "http" are different schemes that
HttpServletResponse.encodueURL() cannot encode the existing session id
(for "http") into the "https" URL, thus practically prevents the session
passed on to "https".

This IS a problem. Many handheld devices don't support cookie at all. I
am supprised that nobody has declared successfully solving this problem
yet.

Brigger, can you please check when turning off cookie, is the
"jsessionid" correctly encoded into the returned "https" url?

Thanks.

Are you encoding the cross-protocol links (with
HttpServletResponse.encode[Redirect]URL())?

The only reason I ask is that it seems strange that it does OK with
cookies
but not with URL encoding: the code paths are similar, so I'd expect it
to
fail with both or succeed with both.

something else that may be worth checking... are apache and tomcat running
on the same box?  the default workers.properties assumes they are, so if
you're using that and tomcat is on a different box apache will be trying
to connect to localhost when it should be looking for the box that tomcat
is on...  just a thought.

Re: Weird thread/security problem

[Dmitri Colebatch]

Application wide content should be stored in the context, not as servlet
variables.  This is because if the servlets are load balanced across
multiple jvms, or if servles implement the SingleThreadedModel then tomcat
will need to ensure that all instances of servlets on all jvms share the
one object.  correct?

Power reset on NT/IIS kills Tomcat?

[Ken Grigg]

Hi all,

I am running Tomcat 3.2.3 on NT/IIS with the Jikes compiler, and noticed if
the server is reset (i.e. power glitch) without a normal shutdown, the work
directory seems to get corrupted. The symptoms are that the JSPs can't be
compiled until the associated class files (that otherwise compile fine) are
deleted from the work directory.

I couldn't find any discussion on this problem in the archives or the web,
except for the possibly related discussion at:

http://www.javaclue.org/tomcat/patch32b6/letspatch.html#step5

I was surprised to see that patch (against 3.2.1) hadn't been applied to
3.2.3, but it didn't work anyway.

In case it was Jikes, I tried manually recompiling the JSP source in the
work directory, and that worked fine. (The JSP source gets regenerated OK...
it just won't compile).

Any advice/ideas would be greatly appreciated!

The jasper.log file gives:
2001-07-26 11:33:06 - JspEngine --> /contextAdmin/contextAdmin.jsp

Re: Problems with authentication

[Mattias Karlsvaerd]

Thank you! this will help me understand how it works
with j_security_check, j_username and j_password
better.
But i still have the problem that the authorization
doesn't work with apcach + tomcat.
I've read that other people that have the problem have
got it to work on tomcat standalone server!?

RE: Help!! Apache won't redirect to tomcat

[Dmitri Colebatch]

Mike,

Sorry for being forgetful... but what page are you requesting?  I'm just
checking that you do have a valid JkMount that will match the page
requested, and that it matches something that can be requested via tomcat
directly.

For example.  If you are trying to request
http://localhost/examples/Foo then you should have JkMount /examples
ajp12 or similar in your httpd conf, and also
http://localhost:8080/examples/FooServlet should work.  Does this sound
right?  

Sorry I haven't completely followed this so I hope I'm not suggesting
things that might've already been suggested.

cheers

Tomcat VHost configuration under Linux

[Loïc Lefèvre]

Hi
After 3 days passed on the configuration of Apache 1.3.12+Tomcat 3.2.3
(mod_jk)
I'm going mad !!! :( Could someone please send me their configuration files
(mod_jk.conf + server.xml + web.xml (tomcat + appli)). Note: the files for a
web archive which work !

After that, I'm going to work in source files >:)

Re: Problems with authentication

[Andrew Robson]

Hi,
  If you get it to work in tomcat standalone (have you
tried that?) then you need to add 
JkMount /examples/jsp/security/login/j_security_check ajp13
(or ajp12 if that's the connector you are using)
to httpd.conf to get it to work with apache. 
Otherwise apache won't know to delegate the handling of
this url to tomcat.

jsp not storing session state

[Stewart Allen]

I'm running Tomcat 3.2.3 from a custom classloader inside my 
application. Everything seems to be working (jsp compilation, etc) with 
the exception that it's not storing/restoring state correctly. For 
example, in the numberguess example :

  http://localhost:8080/examples/jsp/num/numguess.jsp

It always tells me I have made 1 guess. My classloader is telling me 
that a call is made to get the resource "num/NumberGuessBean.ser". Where 
is this filed supposed to come from? There exists no such file so my 
loader correctly returns null.

Any ideas would be appreciated,

stewart

Re: WebappClassLoader question

[Vincent Massol]

Thanks Alex,

I don't think the standard classloader mechanism is involved here. I believe
it is a 'feature' of Tomcat and more specifically of it's WebappClassLoader.
When you do standard java code and you have the following situation :

1st -> 2nd --- (using reflection) --> 3rd (not in classpath)

then the error always happen in the 2nd class and you can put the code
between a try catch block and you'll be able to catch the
ClassNotFoundException. However what happens here is that the error happens
when calling a method on the 1st class that instanciates the 2nd class !
This is what I don't understand.

Am I dreaming or is this a behaviour of Tomcat 4 ?

Thanks

Selectively publishing servlets on a port.

[Mandar Joshi]

Hi All,

I want to restrict a servlet on certain port (connector). 
I don't want other connectors to see it. Is it possible to do.
I am using tomcat 3.2.2 on Windows 2000 as a standalone setup.

Alternately is it possible to turn on the authentication for a single
servlet ?

Thanks in Advance
Mandar

Apxs problem

[Aaron Cooper]

HI folks

I re-installed the apache web server , building it from source.  Now I am trying to 
configure tomcat with apache using the mod_jk web adapter.  However, when I run apxs, 
it produces the following message:

gcc -DHPUX11 -DUSE_HSREGEX -DUSE_EXPAT -I../lib/expat-lite -fpic -DSHARED_CORE -
DSHARED_MODULE -I/usr/local/apache/include -I../common -I/opt/java1.2/include -I
/opt/java1.2/include/hp-ux -DHPUX11GCC  -c ../common/jk_ajp12_worker.c
apxs:Break: Command failed with rc=255
Error with apxs


I've read the mod_jk howto website, and it says to rebuild the apache web server from 
source... but that is what I just finished doing :)

Any ideas? 

Cheers

Aaron

Since your original post, the above has changed (ajp12 to ajp13).
What does your mod_jk.log now have?

Also try "netstat -a" after starting Tomcat to check that it is
listening on port 8009 (where ajp13 listens).  If it is not,
then your server.xml isn't correctly configured for ajp13, in
which case cut and paste the relevant section and post it here
-- someone might spot something you've missed.

Also check workers.properties -- make sure ajp13 is listed on
the worker.list line and there are a few lines starting
worker.ajp13...  (this should all be fine by default, but it
doesn't hurt to check).

Re: Weird thread/security problem

[Craig R. McClanahan]

Tomcat runs multiple individual threads per *request*, not per *user*.

99.9% of the time, this kind of thing is caused by application programming
errors related to threading.  For example, if you use an instance variable
in a servlet to store information specific to a particular request, and
access that servlet with more than one request at the same time, you will
observe this kind of problem.  The reason for this is that there is one
instance of the servlet class, and therefore one instance of the
(incorrectly shared) instance variable.

To avoid this kind of problem, store information specific to a particular
request *only* in local variables, request attributes, or session
attributes.  Use instance variables in your servlet *only* for things you
really do want to share.

First, SingleThreadModel deals with the "multiple simultaneous requests"
problem, but it does *not* deal with keeping per-user state information
across multiple requests.  For that, you still need to use sessions.

Second, SingleThreadModel does *not* deal with all of the issues related
to multithreading.  For example, it's very easy for the same user to
create multiple simultaneous requests, and your session variables need to
be aware that they might be accessed simultaneously by multiple
threads.  Here's two simple cases that do this:
- Framed presentation (the browser will typically send up to four
  simultaneous requests for the frames).
- User submits a long-running request, presses STOP, and then
  submits another request before the first one has finished.

Third, (at least on Tomcat) you are *not* going to like the performance
impact of using SingleThreadModel servlets.  Although the servlet spec
allows the container to create a pool of SingleThreadModel servlets,
Tomcat does not do so.  Therefore, using this technique in Tomcat is
equivalent to putting "synchronized" on the doGet() and doPost() methods
of your servlet - only one request at a time for *any* user is processed.

Can you tell I think depending on SingleThreadModel is not a good
idea?  :-)

Configuring default context

[Wirianto . Djunaidi]

Hi,

I need help with configuring the context with Tomcat 3.2.2 on Windows NT.
Basically I only want one context with my tomcat server, I had
removed other context from webapps directory except mine and
change the server.xml with this for the context:


  
and the AutoSetup ContextInterceptor is running.

Here's my problem, when I start this up on Windows it will
try to load 2 Contexts: Context( ) and Context(ROOT).

Funny thing is, I ran the exact same configuration on
a Sun box running Solaris 2.7, it load up Context( ) only
with no problem.

So, what should I do here?

Thanks,

If you want Tomcat 4.0 to automatically do this redirect for you, then you
need to set up a security constraint inside the web.xml file of your ROOT
web app, and have that constraint require SSL.  For example:

  

...


  
The Entire Web App
/*
  
  
CONFIDENTIAL
  


...

  

In this scenario, we do not have an , so we will never
challenge the user for a username or password.  However, the transport
guarantee says that this entire webapp (i.e. all URIs that match "/*") can
only be accessed via SSL, so Tomcat will do an automatic redirect (to port
8443 in this case, because of your server.xml configuration below).

The web app class loader in Tomcat 4 is based on java.net.URLClassLoader,
and has the same basic class loading behavior.  In particular, when a
class A is loaded, all the classes that A directly references (i.e. listed
in import statements, used as a variable declaration, and so on) are also
loaded.  This is done recursively on the referenced classes, until the
entire tree of references is resolved.  If the load for class A fails, you
will get ClassNotFoundException.  However, if the load for one of the
referenced classes fails, you will typically get NoClassDefError instead
(and the class named in the error message may or may not be the one that
is actually missing, which complicates debugging this problem tremendously
:-).

A good rule of thumb to avoid this kind of problem -- if you need to add
classes to your CLASSPATH at compile time (when rebuilding the entire
app), be sure all of those classes are visible to the web app at runtime.

Using reflection, on the other hand, lets you defer loading of "dependent"
classes until runtime, and you can deal with ClassNotFoundException errors
that you might run into.  Note however that, even if you load a class
dynamically, *that* class still contains direct references to other
classes that must all be resolved in the manner described above.

Craig McClanahan

PS:  One place where the Tomcat 4 class loader *does* vary from the usual
class loader behavior is in the order of places it looks to load a
class.  The usual pattern in Java2 is to delegate to the parent class
loader first, then look locally.  Tomcat 4 does the opposite -- it checks
in /WEB-INF/classes and /WEB-INF/lib of your web application *before*
looking up the parent class loader chain.  This means that, if you have a
class in the $CATALINA_HOME/lib directory (shared across web apps), and a
version of that same class in your web app, the version in your webapp
wins.

Try putting the properties file in /tomcat/common/classes (which you might
have to create first).  That way, it will be made available through the
same class loader that the PoolMan classes are.

If that doesn't work, then some digging inside the PoolMan sources will be
needed to figure out what is going on.

3.3 is still under heavy development (I believe they reached their first

Bug 2290 - Sessions don't work => 3.2.3

[Noble, Joseph A]

Does Bug 2290 reported for Tomcat version 3.2.2, Sessions don't work at all,
apply to Tomcat version 3.2.3 also?  I appear to be having similar problems.
When I invalidate a session, under 3.2.3 in a protected directory from a JSP
page, I'm not asked to log in again, I'm just given a new session ID.  The
only time I'm asked to log in is the intial time entering the protected
context.

losing connection to 8007

[Gary Rather]

I have a server running on solaris with tomcat 3.2.2 with mod_jk

The server runs fine for days then for some reason start getting
Errors:

[jk_ajp12_worker.c (601)]: ajpv12_handle_response, error writing back to server
[jk_connect.c (143)]: jk_open_socket, connect() failed errno = 146
[jk_ajp12_worker.c (152)]: In jk_endpoint_t::service, Error sd = -1

As of this point must stop the server using shutdown.sh does not work. 
(Because we can't talk to 8007)
Do a kill on the tomcat process and restart all works again.

So far we have noticed this happen on two different occasions.

Need ideas what to look for when it happens again.  We have another server 
which happens to be
running od_jserv and we have seen it here also.

WAR files

[Erin Lester]

Can anyone point me to some information about creating WAR files.
Supposedly you can create them with deploytool, but I only know how to do
this with the gui version and don't have an x-windows server on the server
I'm working on.  I've also read that you can use jartool to create WAR
files, but the instructions said you will need to create your own version
of the deployment descriptor.  What does this mean?  create my own
web.xml?  I have a web.xml but don't really use it for much (not all the
servlets are in the web.xml).
 
Is there anything special we need to do in the web.xml/deployment
descriptor file? and will a WAR created with the jar tool preserve the
directory structure of the application?


Thanks!

mod_jk problems

[Andrew Ormsby]

Hi,

I'm using Apache 1.3.20 and Tomcat 3.3m4 and I have the following
problem:

I have a simple servlet which responds to GET requests by returning a
web page with some binary content.  The precise content is selected by a
parameter, e.g: http://host/servlet/get?p=1

Accessing the servlet from Tomcat standalone, everything works fine.
However, when using mod_jk (AJPv13) to access Tomcat from Apache, things
work well until after the server has been under heavy load.

Once the server has been loaded up, I start getting bizarre behaviour:
Apache will return the output of the *previous* servlet invocation.
Given the sequence:
http://host/servlet/get?p=1
http://host/servlet/get?p=2
the first request will return some old result and p=2 will return the
result expected from p=1.

>From my servlet logs, I know that the p=1 request reaches the servlet
and the right content is generated (and I can confirm this by accessing
the servlet directly on port 8080, by-passing Apache).  But Apache
resolutely returns the "old" content.

This feels like some kind of buffering problem - perhaps in mod_jk, or
maybe in Apache itself.  Has anyone else seen anything like this?  Any
suggestions on how I can diagnose the problem?

Very easy. Use Ant: http://jakarta.apache.org/ant/index.html . Ant is 
the default build tool (like 'make') for Jakarta applications.
And take a look at the Tomcat source examples/build.sh and 
examples/build.xml files to see how Ant builds a WAR file.

Yup, it means create your own web.xml. Just make sure it is in 
appname/WEB-INF/.

Re: mod_jk problems

I've seen this exact problem in 3.3m3, but I don't have any

has been better in this respect than ajp13, but the problem 
isn't gone.  I'm planning to spend some time in August or 
September working through the mod_jk code to check on a

On a Linux box, an uninstall is not needed. I assume it is the same on 
an MS-Windows box. The different versions of Tomcat are simply installed 
parallel to each other. You do have to shutdown the old install, as the 
new install will try to use the same port numbers (8007, 8009, 8080, etc).

Re: howto redirect

[djhutchison]

I asked this on another thread of discussion but never got an answer. Is
this automatic redirection to SSL new for Tomcat 4.0? I'm using 3.2.3 and
when I set this user-data-constraint it appears that Tomcat verifies access
via SSL but does not redirect if it is not. From your response below I
assume this is 4.0 only.
Thanks,
Dave

If you want Tomcat 4.0 to automatically do this redirect for you, then you
need to set up a security constraint inside the web.xml file of your ROOT
web app, and have that constraint require SSL.  For example:

  

...


  
The Entire Web App
/*
  
  
CONFIDENTIAL
  


...

  

In this scenario, we do not have an , so we will never
challenge the user for a username or password.  However, the transport
guarantee says that this entire webapp (i.e. all URIs that match "/*") can
only be accessed via SSL, so Tomcat will do an automatic redirect (to port
8443 in this case, because of your server.xml configuration below).

Intermittent ferrors with ajp12 with tc3.2.1 on solaris with stronghold (apache)

[John Thompson]

kind Sir/Madam,

This problem has fixed itself twice and now appeared again

I'm running on Solaris 2.6, Tomcat 3.2.1, Stronghold 3.0 (secure apache).

I've been running happily making and testing servlets using ajp12 and ajp13, 
then it stops working.

I start tomcat, start stronghold, try the servlet and get the following in 
mod_jk.log (set to debug) each time I try a page on tomcat.

Bizarre - if I wait for a while I get java.io.IOException on the command 
line.

I get the following errors in mod_jk.log when set to debug.

[jk_uri_worker_map.c (344)]: Into jk_uri_worker_map_t::map_uri_to_worker
[jk_uri_worker_map.c (434)]: jk_uri_worker_map_t::map_uri_to_worker, done

[jk_ajp12_worker.c (163)]: Into jk_endpoint_t::done

The first time I waited a while and it fixed itself.  Restarting does not 
help (does it hinder?).

This time,  I wait a while,  get the IO Exception,  then try shutdown which 
fails (can't connect) then I try again and it starts working.

I assume I can't get a socket for some reason but I'm sure I checked 
'netstat -a' which showed no traffic on that port.

Please can anyone tell me what is going on.  Browsing the archives I see 
something about queues?

I have to confess that I tend to not bother restarting the webserver each 
time I restart tomcat (does this make any difference?)

Thanks in advance,
Jon.

Yes it's new in Tomcat 4.0.  So is the explicit spec requirement that a
container act in this way, in Servlet 2.3 PFD3, section 12.8, p. 92).  The
servlet 2.2 spec was silent on this point, although some containers behave
that way.

If the Virtual Machine you downloaded is certified to work with Windows NT,

If you expect those JAR files to be visible to all of your web
applications, then the answer is no ... until you copy those JAR files
into the "lib" directory of your Tomcat 4.0 distribution.

The CLASSPATH variable is ignored by the (standard) Tomcat 4.0 startup
scripts, which very carefully set the CLASSPATH required to run
Tomcat.  You can certainly change these scripts (it's open source, yadda
yadda) but you will quickly venture into unsupported territory, where you
have to solve your own mysteries about how class loaders work :-).

Re: WebappClassLoader question

[Vincent Massol]

Thanks Craig,

However I am still not sure this mechanism explains the problem I had. It is
not easy to describe in word so I'll write it in java code instead.

A.java

public class A implements HttpServlet
{
  public void doGet()
  {
log("before error");
B myB = new B();
log("after error");
  }
}


B.java

public class B
{
  public B()
  {
  }
  public doSomething()
  {
try {
  Class myClass = Class.forName("C");
  // call the method by reflection ...
} catch (Exception e) {
  log("I would have thought here");
}
  }
}


C.java

import junit.framework.*;

public class C extends TestCase
{
...
}


Now all of this is packaged in a war, classes A and B and in a jar put in
WEB-INF/lib and class C is put in WEB-INF/classes. The junit jar is *not*
put in WEB-INF/lib.

Calling the servlet A result in an error occurring between the logs "before
error" and "after error" and the log "I would have thought here" is never
printed because the error happens _before_ ... This is what I don't
understand.

Any idea ?
Thanks a lot

The web app class loader in Tomcat 4 is based on java.net.URLClassLoader,
and has the same basic class loading behavior.  In particular, when a
class A is loaded, all the classes that A directly references (i.e. listed
in import statements, used as a variable declaration, and so on) are also
loaded.  This is done recursively on the referenced classes, until the
entire tree of references is resolved.  If the load for class A fails, you
will get ClassNotFoundException.  However, if the load for one of the
referenced classes fails, you will typically get NoClassDefError instead
(and the class named in the error message may or may not be the one that
is actually missing, which complicates debugging this problem tremendously
:-).

A good rule of thumb to avoid this kind of problem -- if you need to add
classes to your CLASSPATH at compile time (when rebuilding the entire
app), be sure all of those classes are visible to the web app at runtime.

Using reflection, on the other hand, lets you defer loading of "dependent"
classes until runtime, and you can deal with ClassNotFoundException errors
that you might run into.  Note however that, even if you load a class
dynamically, *that* class still contains direct references to other
classes that must all be resolved in the manner described above.


> Thanks
> -Vincent

Craig McClanahan

PS:  One place where the Tomcat 4 class loader *does* vary from the usual
class loader behavior is in the order of places it looks to load a
class.  The usual pattern in Java2 is to delegate to the parent class
loader first, then look locally.  Tomcat 4 does the opposite -- it checks
in /WEB-INF/classes and /WEB-INF/lib of your web application *before*
looking up the parent class loader chain.  This means that, if you have a
class in the $CATALINA_HOME/lib directory (shared across web apps), and a
version of that same class in your web app, the version in your webapp
wins.

listorders
/cust/listorders.jsp

As someone else pointed out, you could also have modified your actions to

I'm lost here, where you put the Junit.jar? , because it will be on some
place? no? to allow you load classes from , no?, i think you need the
entire inheritance chain for resolving dependencies, so you need
Junit.jar in some place in classpath AFAIK.. this is the simple dumb
explanation i know, but is what i'm seeing on your example.. 

Can you make a simple main example trying to do what you want to do,
without involving a servlet container.. i dont know how you can load (
using  reflection for it doesnt matter ) a class without his entire
inheritance chain present ... 

Only a wild thought, i'm not an expert on anything so... take it me too
seriously .. :)

oracle 8.7.1 with tomcat

[Manhong Wu]

I have a project runing fine on NT connecting to
oracle 7.3.3 by using tomcat 3.2.1 with Jbuilder. Now
I have to move the database to 8.1.7, then I download
classes111b.zip from 
http://otn.oracle.com/software/tech/java/sqlj_jdbc/software_index.htm
and map the lib to that zip file, but looks like I can
not set up connection with database.
 
Is there another suggestion ?
 
thanks

Re: WebappClassLoader question

[Craig R. McClanahan]

Hmm, I just tried a case like what you have below.  As long as B does not
explicitly reference class C, then it works.  In other words, in my
example where you've got the "// call the method by reflection" comment, I
added

  Object c = myClass.newInstance();

and got the class not found exception at "I would have thought here".  On
the other hand, if I changed the above line to:

  C c = (C) myClass.newInstance();

(and compiled with class C on the compiler classpath, but not in the
webapp), then I get the error in between "before error" and "after error".

This makes sense, because the latter statement makes B explicitly
dependent on C, where the former doesn't.

I'll mess around some more, playing with JAR-ing up some but not all the
classes involved.

One more follow-up ... this works correctly for me with A and B in a jar
file under /WEB-INF/lib, and C unpacked under /WEB-INF/classes as well.

Displaying exceptions

[Erick Todd]

I am having a problem of errors that were not caught by being printed to 
the terminal.  Is their a way to redirect these to a file or to the 
tomcat logs?  

Also when an exception is handled by jakarta can I change the stacktrace 
to some default message that is a litle nicer to our friends on the web, 
and maybe even log the error?

Any help on either of these would be greatly appreciated.
