mod_jk2/tomcat 4.1.29 uri mapping

[Stefan Proels]

Hi,

I've encountered a strange problem which occurred after updating from 
mod_jk2 compiled from the jakarta-tomcat-connectors-4.1.27-src.tar.gz 
distribution to the new version from  
jakarta-tomcat-connectors-4.1.29-src.tar.gz. I have the following workers 
definition in workers2.properties:

[channel.socket:localhost:9602]
info=Ajp13 forwarding over socket
debug=0
host=localhost
port=9602
tomcatId=localhost:9602

[ajp13:localhost:9602]
channel=channel.socket:localhost:9602
tomcatId=localhost:9602

[uri:/erfx/*]
worker=ajp13:localhost:9602
context=/erfx
tomcatId=localhost:9602

This works fine with the mentioned mod_jk2 from tomcat 4.1.27. However, 
with 4.1.29 only the uri /erfx/ gets mapped as expected but /erfx/foo.jsp 
for example doesn't, i.e., the request is not processed by tomcat but the 
file is delivered in its raw form by apache. When I add another explicit 
mapping [uri:/erfx/foo.jsp] it works again. It seems the "*" in the uri 
no longer works from some reason. Similarly, when requesting an uri which 
does not directly correspond to a JSP but should be passed to a servlet, 
I get a 404 (not found) from apache.

I'm running Apache 1.3.29 with Tomcat 4.1.29 on a Linux host. As already 
stated, the same configuration works fine when using the mod_jk2 from the 
4.1.27 connector sources. Could someone please shed some light on this 
and tell me how to get the new mod_jk2 to work? Thanks in advance.


CU,
Stefan

Slow on Linux

[Yonatan Goraly]

I am in the process of evaluating Linux as a server platform for my 
application (this is my first Linux experience).
The environment is:
- Single AMD Opteron 1.8 GHz
- Tyan motherboard with 1 GB memory
- Mandrake Linux 9.2 AMD64 RC1
- SUN JDK 1.4.2_02
- Tomcat 4.29, without Apache web server

The first impression is that the application is extremely slow. I found 
out that calling 
getServletConfig().getServletContext().getRequestDispatcher(url).forward(request, 
response); can take about 500 ms (I put one log command before the call, 
and the other at the beginning of the forwarded JSP page, so I know that 
the only call my application does between the log commands is the 
forward call)

Please advise

Re: HTTP Error 302

[Günter Kukies]

Hi,
after investigating the Problem, we found that we generate a redirect to
login when
the session is invalid. We have a servlet, that generates Images. If the
client requests the Image servlet directly everything is fine. The session
is valid and the user gets his image. But when the client want's to generate
a PDF with FOP on the same webapplication where the Imigegeneratorservlet
is, we dont't get a valid session. The request to the Imagegenerator is
comming now from the webapplication and not from the client. So there is no
session and we generate a redirect to login. I monitored the datatranfere
with tcpdump on the loopback device 127.0.0.1 and there I saw the HTTP 302.

What is the best way to handle this kind of session problems.

Thanks for answeres

Günter

Re: tomcat start and stopping

[Oscar Carrillo]

I have some daemon scripts on my tutorial site. I wrote them for Linux but
you should be able to change things if need be. I use chkconfig to make
the sym links for the different runlevels, but you can just read the
chkconfig line comment at the start of the script and do it yourself. I'm
not sure how Solaris handles the runlevels sort of thing (Sys V, etc.),
but it should be fairly simple to adapt.

Re: Servlet Response Wrapper not able to get JSP data

[Vincent Chain]

Ok, I got this figured out. 
 
I was confused for a while where the data buffering happened: the buffering happens at 
the PrintWriter that I created when the getWriter() is called on the wrapper. So i 
need flush the print writer in order to make the data available to the underlying 
outputstream, which is my wrapper outpustream.
 
Problem solved. sorry for the confusion.
 
thanks

Re: Slow on Linux

[Oscar Carrillo]

I'm no expert on Servlets so I'm not sure what's involved with all those 
calls, but it doesn't seem like it could be anything that takes 500ms.

Have you tried running "top" while this is going on? You can set it to 
update quickly so that you can see what's taking up the processor, if 
anything. In particular, if it's a java thread (process) or Apache 
process.

Are you compiling Apache and connector from source? Have you compiled a 
new kernel? Have you done all the updates to Mandrake? In particular nptl, 
gcc, glibc, and kernel.

I don't know if many people are using Opteron here. You are picking a
pretty new hardware architecture for your first Linux experience.  I'm
interested to see how many others have experience with this hardware.

Re: shared object cache

[Rob Augustinus]

thanks,

1) That's exactly what I would like to do, but I'm not quite sure how to do
this. Could you point me to some documentation?
2) I have thought about the complications of the cache, and indeed I need to
be carefull. On the other hand though it is not that critical in this 
application.



Christopher Schultz wrote:

Rob,

I have written a PersistenceManager class that handles all database
access and uses the SQLData interface to map java objects to
User Defined Types in the oracle database. Every request now
has to create a new instance of the persistencemanager so there is
no sharing whatsoever. I would like the persistencemanager to look
in the object cache first and if the object is not there retrieve it
from the database. I need a way to keep this cache in memory
so all requests can use the same cache.


I would do two things:

1) Put your PersistenceManager in the application scope, and re-use it 
all the time instead of doing "new PersistenceManager" for every request.

2) Have your PersistenceManager do its own cachine. One of my favorite 
object caching techniques is to simply use a java.util.WeakHashMap. 
The WeakHashMap works with WeakReferences, so you can fill it with 
data, and the GC will purge some of it for you if it needs some memory 
back.

It works just like any other Map, except that you aren't guarenteed to 
get your object back, later :)

This may sound sketchy, but it's a pretty good cache because it works 
the same all the time: if you have a cache miss, you go to the database.

Don't forget that caches are complicated: when data changes, you have 
to make sure that the cache gets updated. If you have multiple clients 
and a single database, this gets to be a real nightmare. Only cache 
things that don't need to be sync'd up-to-the-minute. For those 
things, *always* go back to the db.

In this case the class name is AdminGroupServlet and the corresponding

/learnweb/module/admin/userinterface/web,
however tomcat doesn't seem to resolve the above URL correcotly.

I tried to request example JSPs which came with tomcat (in
webapps/examples), and they worked, howewer I had no success with my own
classes. When I call startup.sh, I get the following messages:

Using CATALINA_BASE:   /data/htdocs/learnweb/jakarta-tomcat-4.1.27

Using CLASSPATH:
/usr/local/j2sdk1.4.2_02/lib/tools.jar:/data/htdocs/learnweb/jakarta-tomcat-

I tried to add the path to my classes to CLASSPATH in catalina.sh, but
after that I could not use tomcat at all. Any ideas, what I am doing wrong?

Re: mod_jk2/tomcat 4.1.29 uri mapping

[Dionisio Ruiz de Zarate]

i have the same problem. i must to downgrade to the 4.1.27 version.
there is other problem; if you have one dir with, for example, images, you
must to map the directory.

[uri:/erfx/*]
 worker=ajp13:localhost:9602
 context=/erfx
 tomcatId=localhost:9602

[uri:/erfx/images/*]
 worker=ajp13:localhost:9602
 context=/erfx
 tomcatId=localhost:9602

in other form doesn't run.
in the 4.1.27 version you dont have to mapp the subdirectories.

RE: Production Issues | Correction

[Arnab Chakravarty]

Hi,

One correction in the mail.

>What do you use to balance the load between the apaches ?

-We are using the mod_jk to load balance between tomcats and not apaches (for apaches 
we have a hardware loadbalancer in place). The load is not high during the other week 
days but only twice in a week.

>Some things you have to keep in mind:

-First of all, I need to know what are you basing your thoughts/conclusions on ? I 
need more details on why it isn't good enough. 

-How can we inform the each worker about other workers. It seems we need also the 
amount of sessions logged on each tomcats during this time. Any way to find this bare 
minimal changes, say with a jsp page ?

>Do you use sticky sessions ?
>When you see high load on the 2 instances do they have a proportional
>number of sessions (or is each sessions causing more load than usual) ?

-Yes, we are using sticky sessions. Yes the 2 instances are proportional (not from the 
session count, but from the database connections each has and both are observed above 
400 connections)and other instances are cool enough this time. But, apache reach their 
max client connections and other tomcats are sitting their with not much load and 
seems that this load is directed to the already clogged up tomcats (Just a thought, 
not sure!!!) and site does not respond well under these conditions and lead us to kill 
these specific tomcats with high thread counts.

But my point is why direct all the load to a specific tomcat and not distribute it 
evenly ? Then, what worth is the load balancer for. This is not understood well from 
the load balancer settings or either mod_jk is not intelligent at all or better make 
it intelligent / replace it.

Comments???

our findings with Apache2.0.47/Modjk2/Tomcat4.1.29/IBMJDK1.4.1 and sig 11s

[David Muller]

I have seen numerous postings about sig 11 problems with few remedies so here is one I 
hope helps someone.  We put together a huge matrix of Java, Tomcat, Apache and OS 
parameters and finally worked around a jdk bug.

Under fairly heavy load (7-8 transactions/s) we were getting sig 11s with the Sun JDK 
1.4.2_02.  We weren't getting much in the way of stack traces to try to track down the 
problem so we switched to IBM JDK 1.4.1.  We ended up having to turn JIT optimzation 
off like this in the tomcat startup.

export JITC_COMPILEOPT=NALL{org/apache/tomcat/util/buf/Ascii}{parseInt}

also did extensive analysis of garbage collection with these two entries in JAVA_OPTS
-Xgcpolicy:optavgpause -verbosegc

first one seems similar to Sun's conncurrent gc - 2nd one for logging each gc

One thing which helped us find it was cranking the ConnectionTimeout down to 1s in the 
Tomcat server.xml.

We will probably revist the Sun jdk at some point.

Tomcat JSP/HTML caching

[Neal]

Is there anyway to cache the output of JSP and HTML pages served by
Tomcat or do I need an HTTP server for this (e.g. Apache, IIS)?

I have a site begin hosted by Tomcat Standalone which relies upon XML
web services to render the contents and consequently the page render
time is really slow. 

Please let me know if there's solution.

For one thing, whether you guys know it or not, Java is competing against MS
.NET. I surfaced specific issues that need to be covered. I have a case
where the requirements are Win2K and IIS. Neither Linux nor Apache are
viable options, although I've argued for, at least, Apache. I'm doing good
to get Tomcat, okay? I don't want to do C# as that doesn't port more than 5
micro-inches from the MS platforms. This sort of stuff makes it hard to sell
Tomcat.

No, I went item-by-item thorugh the dox that were shipped with the product.
Often I was looking at
http://jakarta.caselle:8080/tomcat-docs/jk2/jk/workershowto.html or
http://jakarta.caselle:8080/tomcat-docs/jk2/jk/iishowto.html. I was making
the case that both of those documents need to be either fixed or removed
from the distribution. In fact, I stated that plainly. You must not have
read that.

Actually, I would gladly do so. I am considering compiling my notes for
subbmital after I get this stuff working. I *really* don't want to do .NET.

Yep and these are the offending lines;

---
workers.properties - A file that describes the host(s) and port(s) used by
the workers (Tomcat processes). A sample workers.properties can be found
under the conf directory.
uriworkermap.properties - A file that maps URL-Path patterns to workers. A
sample uriworkermap.properties can be found under the conf directory as
well.
---

Neither workers.properties nor uriworkermap.properties are shipped with the
product, contrary to what is clearly written insaid dox.

If you'd truely read my email then you'd have noticed that I never mentioned

Hacking the sources is something I am specifically prohibited from doing.
Also, with that error rate, it is better to not have it and admit that IIS
isn't supported, rather than embarras one's self by exhibiting such
problems. This is

[santoshsprabhu]

Hi,


As mentioned in the changelogs of Tomcat version 5.0.10 MX4J 1.1.1 is being replaced 
by JMX 1.2 RI 
Please refer to page http://jakarta.apache.org/tomcat/tomcat-5.0-doc/changelog.html 
for details.
Has any one tried out to get the MBeans in this new implementation ?
I am trying to get the MBeanServer and access the MBeans exposed by Tomcat.
Any help in this direction will be deeply appreciated

RE: IIS is not supported in Tomcat 4.1.29.

[Tom Lyle]

Jesus, what a way to start a Monday morning. Is there really any point in
shouting at each other like this? If you've still not got Tomcat working
with IIS try this:
http://www.onjava.com/pub/a/onjava/2002/12/18/tomcat.html I followed that
and got it all working.

Tomcat isn't as well documented as it might be (for reasons that have
already been stated) but theres really no reason to start having a go at
people.

Peace people,

I18N problems with JVM 1.3.1

[Alexandre Roger]

I have a problem with accents that is occurring when I run Tomcat under
JVM 1.3.1, but not under 1.4.

I am trying to convert a byte[] (that comes from a socket in the
production code) to a String. The bytes come from a CGI and are
ISO8859-1. When I do String(myByteArray), I get a question mark
character where I should get an accented character. Following some
advice picked up from the web, I have forced the JVM to start with a
file.encoding=ISO8859_1. This works perfectly when running Blackdown 1.4
but fails when using Blackdown 1.3.1. Here is a demo JSP:

The following JSP:

Convert a byte: <%=  new String(new byte[]{(byte)'é'}) %>
Convert ISO: <%= new String(new byte[]{(byte)'é'}, "ISO8859_1") %>
Encoding: <%= sun.io.ByteToCharConverter.getDefault() %>
Locale: <%=java.util.Locale.getDefault()%>


Here is the CATALINA_OPTS used:
-Dfile.encoding=ISO8859_1 -Duser.language=fr -Duser.region=CA"

If I do a Sytem.getProperty("file.encoding"), I get ISO8859_1 in both
JVM, but sun.io.ByteToCharConverter.getDefault() - which is what
String(byte[]) uses - says ASCII for JVM 1.3 and ISO8859_1 for JVM 1.4.

It would also seem this is not the only setting getting ignored by the
1.3 JVM... The language and region settings result in a locale of fr_CA
for 1.4 but are ignored (and default to en_US) for 1.3

I know I could simply force the encoding as I did in line 2 of the JSP,
but I am trying to migrate a whole lot of code from Websphere to Tomcat
that was written by many developers and would rather not seek all
instances of byte arrays being converted to strings. Moreover, I suspect
this is merely the tip of the iceberg and other occurrences of accents
being garbled might be going on in less obvious places. 

I also could just use version 1.4 of the JVM, but the only widely
available DEB for JVM 1.4 is a BETA. If at all possible, I'd like to use
a production release managed by the debian package manager...

Anyone has any suggestion?

Alex

form authentication doesnt't work well

[cyril vidal]

Hi,

Perhaps the problem is well known.
I'm under Tomcat/4.1.18-LE-jdk14

When I use form authentication, with the following code snippet included in web.xml:




...


declarativetest

/servlet/chapter9.DeclarativeSecureServlet

POST



...





FORM



/formlogin.html

/formerror.html





...





when I access my servlet 
http://localhost:8080/servlet/chapter9.DeclarativeSecureServlet via POST method, I 
have to fill the form http://localhost:8080/security/formlogin.html: that's confrom to 
 the informations given in web.xml ().

However, when I fill correctly this form, I have the output of doGet method of the 
DeclarativeSecureServlet and not the output of doPost method as expected!!

However, all works well when I run the same example with BASIC autthentication method 
instead of FORM one.

Is this bug fixed in a more recent version of Tomcat?



Thanks in advance for your response,

Regards,

Cyril.

tomcat stats and performances

[arinsoun]

Hi to all, I have two questions. We have Tomcat as server for a struts web
application.

- We need do stats for that web application, stats like  what pages user
enter, who user enter more to the application, performance stats ... I have
seen that one choice is do a manual filter, other choice use awstats.  I
would appreciate information about that of someone that have experiencia on
stats, and he can help me to choose the best choice on time and effort.

- The second question is about performance, here we have tomcat and when
most user enter to the application the server don't reply very well. I have
read that is better have APACHE as web server and TOMCAT as server
container, is that true?  would I improve the performance? or the solution
is customize tomcat better?.

THANKS IN ADVANCE. REGARDS.

On apache I would say something like:

You should use Tomcat 5 and precompile your web application to do that 
so that your JSPs are mapped as individual servlets. You can do that 
using the Tomcat 5 deployer tool.

The status servlet will then display statistics for the HTTP connector 
and the indivudual webapps and servlets.

- The second question is about performance, here we have tomcat and when
most user enter to the application the server don't reply very well. I have
read that is better have APACHE as web server and TOMCAT as server

Tomcat HTTP has lower latency than JK, so you'll get better performance 
with HTTP unless there are very few requests for dynamic content. Tomcat 
5 is also a little bit faster than TC 4.1. However, I think your 
bottlenecks come from either your application, the database setup you're 
using, or too little bandwidth (if you have a public site).

AW: Multiple Tomcats handled by one Apache

[Wegener, Dierk]

Hi,

btw I'm using Apache 1.3.27 and Tomcats 3.3.1a and 4.1.24
on Solaris 8. But testing doesn't even work on win2k.

Thanks

I don't know about you, but I have a similar config running for quite a
while now that works like a charm :).  Note that 8007 is the default port
for ajp12 (which is deprecated, even in Tomcat 3.3.x).  Both Tomcats should
be setup to have their ajp13 connector listening to the respective ports.

"Hot" Reload

[Leonardo Lopez]

Hi gurus, I`m using tomcat 4.0.6 and I need to know how to configure, a "hot" reload 
of an application. 
I mean if a put a recompiled class, because it suffered any change, on the directory 
"webapps/Aplication/WEB-INF/classes/..." , how could I make Tomcat detect that change 
and reload that application without using the manager tools. 
("/manager/reload?path=/Application", for instance)

Thanks in advance

How to set the user runnig tomcat ? ( + start/stop problem)

[Julien Oix]

Hi everyone,

I used to run a tomcat 4.1.18 rpm on a linux top box, where I put the
TOMCAT_USER variable in a tomcat4.conf file ( nobody user in my case ...)

Now i try to upgrade to 4.1.29 full archive (jakarta-tomcat-4.1.29.tar.gz)
and I didn't see any doc's on configuring this variable ..

Is the only solution to execute the startup.sh script as the running user ?
( the command line under a root session could be : su - nobody -c
$CATALINA_HOME/bin/startup.sh )

Another problem:

I start tomcat with the method up in the message:

[EMAIL PROTECTED] # su - nobody -c $CATALINA_HOME/bin/startup.sh
Using CATALINA_BASE:   /var/tomcat
Using CATALINA_HOME:   /var/tomcat
Using CATALINA_TMPDIR: /var/tomcat/temp
Using JAVA_HOME:   /usr/java/java

--> gives the process ran by nobody ...

Any ideas ? ( i added the correct env in /etc/profile for every user)

It does this already if you have reloadable="true" in your context settings

RE: HTTP Error 302

[Shapira, Yoav]

Howdy,
It's your responsibility to handle these redirects ;)  After all, it's your generating 
them.  Maybe add an extra parameter to requests coming from the web application so 
that your ImageGenerator knows it doesn't need to authenticate?  Or make the web 
application authenticate before it calls the ImageGenerator?

RE: shared object cache

[Shapira, Yoav]

Howdy,
If you're using servlets,
getServletContext().setAttribute("myPersistenceManager",
myPersistenceManager) would do the trick.  If you're using JSPs, it's
pageContext.setAttribute(...).

The WeakHashMap is one approach: not one I'd use initially, but only if
you run into issues with a more conservative approach.

Re: tomcat stats and performances

[Peter Lin]

 
The first thing you will want to consider is do you really need to use JSP tags.  If 
you read my little article on performance, you'll see jsp tags reduces performance. 
The newest jasper in tomcat5 has a plugin feature, which allows you to convert jsp 
tags to pure java code.
 
You're going to have to be more specific about what type of app it is, whether it is 
going to a database, is connection pooling used, what type of process it handles and 
so on.  The projects that I've worked on using jsp tags chose it for rapid development 
reasons and we accepted that at the beginning.  When you say it doesn't respond very 
well, it doesn't give enough detail for others to assist you.
 
there have been quite a few threads lately on performance, so I recommend reading 
those messages to see if that helps.

RE: Tomcat 4 request filter

[Shapira, Yoav]

Howdy,
That's because modifying the contents of a request is:
a. Much less common
b. Much more difficult
c. Indicates bad design usually

A request is a request: someone asked for something.  If they wanted
something else, they'd ask for something else.  You shouldn't pretend
you know what they want better than they do: it indicates a bad design
either on the UI part making the request or on your part.

What you would need to do: have an HttpServletRequestWrapper with
overriding methods for getInputStream etc. so that when your servlets
call read the request, they read your stream instead.  Your stream would
be based upon the original one with your modifications.

Re: OutOfMemory Error in Catalina

I bet your going down the wrong path for debugging, from the FAQ:

-- You have too many threads running. Some OS's have a limit to the number of 
threads which may be executed by a single process. (Which is what the JVM 
is.) Refer to your OS docs for more information on how to raise this threshold.

It didn't work in what way?  Did the JVM actually allocate 1200MB and
then die with an OutOfMemoryError, or did it never allocate that much
(e.g. because they're not that much physical memory).

>way is to increase the server's maximum file descriptor limit. But I

Then find out how, e.g. by reading your server's docs.  It's usually
ulimit on unix systems.

>Apart from that, is there any other way
>/ utility to find out the root cause of OOM in catalina.out log file.

Yes, it's a called a Profiler, preferably one that will give you heap
snapshot deltas like OptimizeIt.  But if your problem is at the OS level
such as by having too few file descriptors, a profiler won't help you.
Also know that a profiler requires much more memory be allocated to the
JVM to support JVMPI overhead.

As an RPM, the tomcat4.conf file probably provides variables that are 
passed to the init.d scripts for startup and shutdown.

Now i try to upgrade to 4.1.29 full archive (jakarta-tomcat-4.1.29.tar.gz)
and I didn't see any doc's on configuring this variable ..
As noted, the tomcat4.conf file is a Linux convention, likely for 
convenience. This file is not going be in the binary distribution of 
Tomcat from Jakarta.

I would like to request a copy of both the conf file and the init.d 
script loaded by the RPM. It may provide clues valuable in your quest 
and my quest on Mac OS X.

In Mac OS X, similar to the init.d scripts, a script is placed in a 
StartupItems folder and executed as root. However, as one might guess, 
this results in the process being owned by root. I have not found a 
working method of changing this, including, as you suggest below:

Is the only solution to execute the startup.sh script as the running user ?
( the command line under a root session could be : su - nobody -c
$CATALINA_HOME/bin/startup.sh )
Thus, the reason I request the conf and init.d script files. Valuable 
clues may be found in each that could help us both.

Another problem:

I start tomcat with the method up in the message:

[EMAIL PROTECTED] # su - nobody -c $CATALINA_HOME/bin/startup.sh
Using CATALINA_BASE:   /var/tomcat
Using CATALINA_HOME:   /var/tomcat
Using CATALINA_TMPDIR: /var/tomcat/temp
Using JAVA_HOME:   /usr/java/java
[EMAIL PROTECTED] # ps -aux
--> gives the process ran by nobody ...

[EMAIL PROTECTED] # su - nobody -c $CATALINA_HOME/bin/shutdown.sh
Using CATALINA_BASE:   /var/tomcat
Using CATALINA_HOME:   /var/tomcat
Using CATALINA_TMPDIR: /var/tomcat/temp
Using JAVA_HOME:   /usr/java/java
Catalina.stop: java.net.ConnectException: Connection refused
java.net.ConnectException: Connection refused
...snip stacktrace...

And the tomcat processes are always running ...

Any ideas ? ( i added the correct env in /etc/profile for every user)

I'm not sure why you would not be able to stop the process as started. 
Hmmm...

Look forward to hearing from you and others.

Warmest Regards,
Tim

simple classpath / webapp question

[Mark D. Hansen]

Is there any way to put .jar files on a Webapp's classpath other than placing the .jar 
files into the WEB-INF\lib directory?

I've got a lot of webapps, and it is a real chore keeping these WEB-INF\lib 
directories up-to-date as all the various java libraries that they rely on get updated.

Is there maybe a way to specify a web-app specific classpath in the web.xml file or as 
a system property?

Thanks for any help (and your patience with this simple question),

Mark

Re: simple classpath / webapp question

[Ben Souther]

You could put them in TOMCAT_HOME/common/lib.
Then the jars will be accessible to all webapps running in that instance of 
Tomcat.

Tomcat connectors on Aix

[Jose]

Hello.
I need your help to compile mod_jk2 connectors on Aix 4.3.3
I use gcc 3.2.1, libtool 1.4.2, autoconf 2.53, automake 1.5
I have downloaded jakarta-tomcat-4.1.29 and it is works fine.
Now i need apache 2.0.48 works with tomcat and i have downloaded 
jakarta-tomcat-connectors-4.1.29-src (i don't know if i need this version or JK 2.0.2 
Source Release tar.gz)
I have followed steps on notes of jeff 
trawick(http://www.apache.org/~trawick/tomcataix.html#mod_jk2_gcc):
$cd jk/native2
$ chmod +x ./buildconf.sh
$ ./buildconf.sh
$ CC=gcc ./configure --with-java-home=/usr/java131 
--with-apxs2=/usr/local/apache2/bin/apxs

At last Before running make, edit ../../jk/native2/server/apache2/Makefile and change 
the line 
MOD_LINK = $(LIBTOOL) --mode=link $(CC) -avoid-version -module -rpath 
--${APACHE2_LIBEXEC} $(LT_LDFLAGS) $(ALL_LDFLAGS)
to 
MOD_LINK = $(LIBTOOL) --mode=link $(CC) -avoid-version -module -rpath 
${APACHE2_LIBEXEC} $(LT_LDFLAGS) $(ALL_LDFLAGS) -Wl,-brtl
But i get a lot of warnings.

Any idea ?

Thanks.

I don't know about you, but I have a similar config running for quite a
while now that works like a charm :).  Note that 8007 is the default port
for ajp12 (which is deprecated, even in Tomcat 3.3.x).  Both Tomcats should
be setup to have their ajp13 connector listening to the respective ports.

Hi There,

It looks like there is a memory lieak in your code, do you have any

not removing them from the collection when they are being invalidated.

Re: tomcat stats and performances

[Peter Lin]

 
when you say SAP, I take it is refering to SAPDB.
 
The first thing you to do is to time how long it takes to execute the query. If the 
query is not a problem, then I would move on to timing the processing time in struts. 
What I've done in the past is to take some of the production queries and run them 
against the database for increasing loads. typically I will do increasing number of 
concurrent queries and increasing dataset.
 
generally, if your queries are taking more than a couple of seconds, it will be your 
bottleneck.
 
assuming the db isn't the problem, I would time the jsp by getting the time at the top 
and at the bottom. normally no response is the cause of the database and not Tomcat.

RE: IIS is not supported in Tomcat 4.1.29.

[Januski, Ken]

It's hard not to think that there's a lot of misspent energy here. Many
people have problems setting up Tomcat, esp. with IIS, and I'm one of them.
In fact I had a thread that went on for 50+ messages before it got solved.
But generally most people to get their problems resolved. The original
message is so long that I doubt that most people have the energy to go
through it and respond. This really isn't a matter of what should be or what
shouldn't but just of practicality. It doesn't seem to me that this is a
practical way to get your problems solved.

I'm sure others that know far more than me and are more vocal in this forum
will respond as well. But this my 2 cents on the subject.

http://www.onjava.com/pub/a/onjava/2002/12/18/tomcat.html I followed that

Tomcat isn't as well documented as it might be (for reasons that have

RE: tomcat-jg vs tomcat-replication

[jean-philippe . belanger]

I just tried changing to tomcat-replication

and well, that didn't go as well as I wished! :)

Seams like the setAttribute, getAttribute and sessionCreation does work.
Both my server gets the replication messages.

My problem is that the browse never gets the request back! Everything looks
done on the tomcat side but the client never get the response content.

I tried removing the ReplicationValve and I can get the page back, but
replication doesn't occur (duh!) :)

So, here is my log file of the server that received the request:

The page I use to test it is a servlet GET with a Requestforward to a jsp

Any insight would be welcomed.

Hi,

I'm running Tomcat 4.1.18 in production and needing session replication.
I've been able to get tomcat-jg up and running. But after reading some mail
on the tomcat user mailling list, fillip seam to say that this version won't
work with tomcat 4.1.x and that we should use the tomcat-replication (beta
from TC5).

Any advantages to uses the 2nd one? (NIO vs javagroup?) Bugs ?

Just don't want to use the javagroup one now and find out in some weeks that
it's wrecking havoc with our transactionnal servers!

Thanks for your time

Re: IIS is not supported in Tomcat 4.1.29.

[Christopher Schultz]

Roeland,

Before I sound too much like byting the hand that feeds, let me thank you
for the useful information that you have provided.
Fair enough. Although we must be in different time zones, 'cause I 
definately didn't write that at 4:26 AM :)

For one thing, whether you guys know it or not, Java is competing against MS
.NET. I surfaced specific issues that need to be covered. I have a case
where the requirements are Win2K and IIS. Neither Linux nor Apache are
viable options, although I've argued for, at least, Apache.
Okay, let's fix the docs for IIS. What have you found. I was objecting 
to the lack of useful information (other than to point out problems) in 
your post. Please post the *correct* information, and you're more likely 
to get the problem fixed.

We hear "your stuff sucks" a lot, and that doesn't exactly motivate 
anyone to make those people happy.

I'm doing good
to get Tomcat, okay? I don't want to do C# as that doesn't port more than 5
micro-inches from the MS platforms.
The mom project works pretty well. It even comes with a 
servlet-container-type thing.

Actually, I would gladly [submit patches, etc.]. I am considering compiling my notes 
for
subbmital after I get this stuff working.
Excellent! I look forward to reading the updated documents.

Do you mean this HOWTO:

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


Yep and these are the offending lines;

---
workers.properties - A file that describes the host(s) and port(s) used by
the workers (Tomcat processes). A sample workers.properties can be found
under the conf directory.
uriworkermap.properties - A file that maps URL-Path patterns to workers. A
sample uriworkermap.properties can be found under the conf directory as
well.
You are completely right. Those files do not exist in the distros. 
However, you are looking in the wrong distro. Unfortunately, the 
'distro' that I would suggest is *NOT* the Tomcat distro. It's the 
tomcat-connectors distro. The source distro has the source of the isapi 
redirector. Unfortunately, this archive does not (as promised) contain 
example files. The pre-built isapi_redirector.dll file comes without an 
archive, and without those example files in the download directory :(


"
The ajp12  has been deprecated  with Tomcat 3.3.x and you should use
instead ajp13  which is the only ajp protocol known by Tomcat 4.0.x,
4.1.x and 5.
Of course Tomcat 3.2.x and 3.3.x also support ajp13 protocol.
"
If you'd truely read my email then you'd have noticed that I never mentioned
ajp13. I had already read and understood that part. The isue isn't
documented changes, the issues are changes that aren't documented. A slight
difference.
You said the documents hadn't been updated since Tomcat 3.3. That 
passage clearly indicates that they have been (since they mention both 
Tomcat 4.1, 4.2 and 5.x).

> [I can't figure out workers, and I find the workers HOWTO to be

BTW, your quoted portion is not anything that I wrote. I just checked.
That's true: that's why it's in []s

It explains pretty much every line of the workers.properties file.


Yes, with incorrect data.
Really? You said you didn't understand worker types and properties. 
Every type is documented:

ajp12 - old skool not supported by 4.x and later
ajp13 - new skool, also supported by 3.3, so forget ajp12
jni - uses JNI to communicate directly with Tomcat
lb - load-balances across multiple Tomcat instances
Choose one: do you need load balancing? Do you want to use JNI (if you 
don't know what it is, then you don't want to use it)? If not, go with 
ajp13.

I think [the apparently crappy HOWTO is] a better guideline that the source code for 
the
connector,
don't you think?


Hacking the sources is something I am specifically prohibited from doing.
Is this your company policy? You're not allowed to find anything out 
except by reading documentation shipped with a package?

Also, with that error rate, it is better to not have it and admit that IIS
isn't supported, rather than embarras one's self by exhibiting such
problems. This is a quality issue at this point.
You're right, the IIS HOWTO isn't as step-by-step as it should be.

(Before I go on, I'll mention that there's a complete example
workers.prperties file included in the "Worker HOWTO".
No there isn't.
Yes, there is. Click on this link: 
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/jk/workershowto.html

Then, press the "end" button on your keyboard. Voile! A full example 
workers.properties file. You can even copy-and-paste it, then modify it.

I'll make a bet that you haven't even unpacked the Tomcat
4.1.29 binary distro for Win32, eh?
You're got me, there. I've only unpacked the 4.1.27 binary distro on win32.

Nowhere in there, does it exist.
Again, workers.properties doesn't belong to Tomcat -- it belongs to the 
connector project. They are separate. Tomcat also doesn't include the 
JNI headers required to compile C++ code wrapped b

directive/Virtual host problem

Hello List...

In order that a virtual host respond correctly to urls: 

http://mydomain.com

http://www.mydomain.com

I've had to add two host entries in server.xml (one for mydomain.com, the other for

I thought it would have been enough to add the alias directive for the

Are there problems with the alias directive - or am I misinterpreting it's function?

While I am within the host server, everything works fine. But let say

I am able to login, pass the information, and even get the database file

I just get a system beep.
When I check the server, all tasks of copying the file from the secure

I am not using IIS at this time.

XSQL installation

[Daniel Fullum]

I have been trying to install Oracle's XSQL in Tomcat 4.1.29 without
much success.
I am using Windows2k and Java 1.4

The closest I get is by installing all JAR files, including OJDBC14
driver. in ...\WEB-INF\lib\  and creating a context with the
Administration tools.
Even then I keep getting:

Oracle XDK Java 9.2.0.6.0 Production
XSQL-003: Failed to find 'XSQLConfig.xml' file in server CLASSPATH.

No matter how I try to set it or where I put it!

That's the file that contains all the passwords to all the Oracle
databases so it should remain unreachable for users on the WEB.


As you might guess, J2EE and Tomcat are new to me.

If someone can give me a hint at how I should have installed XSQL to
make it available to all applications, I would immensely appreciate. I
was hoping to do it all with the Administration tool.

The procedure provided by Oracle to install XSQL on Tomcat  3.2 does
not work.

RE: simple classpath / webapp question

[Shapira, Yoav]

Howdy,
He already said he needs different versions of those jars, so common/lib
or shared/lib is NOT a solution.

Look at bugzilla (use ant in the description), it might be an ANT config 
related issue. I remember something about files being written to weird
places 
and it was due to ant.

Tim,



Actually[without more digging] - I thought tomcat should be writing to 
$CATALINA_HOME/work


Yeah, that's what I thought it was there for. If it doesn't write to 
the
work dir, it should at least write to the "tmpdir" or whatever that 
thing is.

RE: mod_jk2/tomcat 4.1.29 uri mapping

[Dennis McRitchie]

This problem also does not occur when you build mod_jk2 from
jakarta-tomcat-connectors-jk2-2.0.2-src.tar.gz .

Re: simple classpath / webapp question

[Ben Souther]

I assume from the backslashes in your pathname that you are running on 
Windows. Otherwise, I would suggest using symlinks to point to the jar files 
that need to be updated often.

Since that's not an option, I would go with Yoav's suggestion and use an ant 
script for updating your libs.

Re: jsp cache issue

[Christopher Schultz]

Tim,
Is it similar to:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=18485
This seems to indicate that Tomcat uses ant internally to compile 
(translated) JSP files. Is this accurate?
