Hi,

Is there a way to specify at runtime what worker the load-balancer 
should use first?


For some request, we can't use cookies so we pass the session id via the 
URL or via the query string. We then force the worker using RewriteRule 
and the JK_WORKER_NAME env var.
But then the request doesn't pass through the load-balancer anymore. So 
even if we stop that worker in the load-balancer, it will still receive 
the request instead of being redirected to another worker.


So is there a JK_LB_PREFERRED_WORKER kind of variable or equivalent 
that the load-balancer would use instead of the cookie?


Not directly, you could make use of the cookie and url encoding routing 
facilities of an lb though.


- Make sure the JSESSIONID gets deleted before and the new request 
doesn't contain a wrong ;jsessionid URL encoding
- Either use mod_headers to set a fake JSESSIONID Cookie header to the 
request
- Or use mod_rewrite and append a fake ;jsessionid=... URL encoding at 
the end of the URL (but before the query string).


The value of the Cookie resp. jsessionid would be X.MYROUTE, where 
MYROUTE is the name of the lb sub worker you want to gert chosen by the lb.


Session with id X will not exist on the target MYROUTE, so a new session 
will be created for the request.


Let us know if this works :)

Rainer

Re: mod_jk/tomcat problem

I think you have given the wrong port for the worker configuration.
You should give the AJP port and not the HTTP port for the worker.

 Sure, the -src file is the *source* file of
 tomcat, those need you to 
 compile it and probably run a dist making script
 included in folder. If 
 you just want to install tomcat, download the binary
 packages.

Re: Forwarding with jkmount


Hi Edwin,

Edwin Walsh wrote:

Hi,

First of all I would like to mention that this is my first post on this 
list, I hope that this question is posted in the right place. I have 
tried finding a solution for my problem, but it either doesn't exist, or 
my limited brain can't manage to figure out how to do it (I strongly 
hope it is the latter)


In fact the solution to the problem is non-trivial :)


The situation is the following:
Currently we have several web applications running on a Tomcat 6 server. 
For the sake of this explanation I will call then web1 and web2.
I have apache set up to use jkmount to forward requests from the apache 
server to the tomcat server. The problem is that I can only get apache 
to forward things like www.esat.kuleuven.be/web1 and 
www.esat.kuleuven.be/web2.


I would like to be able to forward things like 
www.esat.kuleuven.be//somefancyname//web1 to the same application on the 
Tomcat server.


I know this is possible with ProxyPassReverse in apache, but I would 
like to be able to do this with jkmount so that I keep the possibility 
to easily jump to a backup server if the main server goes down (Tomcat 
crashes more often for us then the http server does).


To add to the problem, the web applications I am talking about are 
updates from earlier versions. We still have the older versions running 
on older versions of Tomcat and the forwarding rules of 
www.esat.kuleuven.be/web1 need to continue to point to the old server.


As far as I can tell using the location tag in the apache conf file will 
not help since it seems to me that jkmount takes that location as a 
parameter to forward to Tomcat. And since my application is called web1 
and not somefancyname/web1 it cant find it in the web applications folder.


Using a subdomain in a virtualhost could probably fix the problem in a 
way that I could use /somefancyname/.esat.kuleuven.be/web1 for the new 
web application, but it is very unlikely that our system administrators 
will allow us to set up this subdomain. And even if they would it isn't 
really the url I was hoping for.


So in sumary, what I would like is 2 types of links:
www.esat.kuleuven.be/web1 to point to the older web application
www.esat.kuleuven.be//somefancyname//web1 to point to the new web 
application (both have the same name but are on a different tomcat server)


I think the solution should have 2 ingredients:

1) Make sure, that /web/ and /something/web match different JkMounts

JkMount /web1|/* oldworker
JkMount /?*/web1|/* newworker

? matches one character, so the second rule won't match /web1/..., 
except for /web1/.../web1/...


The | character is a shortcut form for 2 rules in one:

JkMount /web1|/* oldworker

is equivalent to

JkMount /web1 oldworker
JkMount /web1/* oldworker

2) Rewrite request to remove /something before forwarding

Have a look at mod_rewrite. With mod_rewrite you can change the URL with 
a pattern based syntax. In order to forward the changed URL and not the 
original URL through mod_jk, you need to also set the pass through flag 
[PT] in mod_rewrite


Now the only thing I'm not sure at the moment is, if in case you rewrite 
the URL via mod_rewrite, the JkMounts are handeled before the rewrite 
(then this should work) or after (then it would obvisouly not).


Play around a bit with the ideas, set JkLogLevel to debug and use a 
RewriteLog with a high level, so you can follow the URL manipulation and 
mapping in the log.


If rewrite is done before JkMount, we'll have another solution :)


Any help would be welcome.
With kind regards,
Edwin

Rainer

It's trying to connect to 127.0.0.1:8009, but on my workers.properties 
file I define that tomcat is listening on 8080:


worker.list=loadbalancer,worker1,worker2

worker.loadbalancer.balance_workers=worker1,worker2

worker.worker1.host=192.168.11.6

worker.worker2.port=8080
worker.worker2.lbfactor=1

Anyone could tell me why is trying to connect to 8009 insted of 8080?


As you can see, it is not only using the wrong port, but also the wrong 
IP. In fact it is trying to use the worker named loadbalancer as a 
normal ajp13 worker instead of as an load-balancing worker. And for ajp 
workers, default host+port are localhost+8009.


Solution: you forgot worker.loadbalancer.type=lb :)

But: see also the other reply. Port 8080 by convention is used on the 
backend for an http connector, which will not work with JK. You need to 
define an AJP connector on the backends and use the port of this 
connector in workers.properties.




Thank you!

Jordi

Make sure you're not using a port under 1024 on UNIX, or Tomcat will have to 
bind that port as root anyway.

Otherwise, you just need to make sure the non-root user has access to the 
appropriate Java and Tomcat files, yes.  I routinely run Tomcat as a non-root 
user on various Linux systems, just by extracting a copy in my user directory 
and making sure I don't use any privileged ports.

Re: Forwarding with jkmount

2008-01-09 Thread Edwin Walsh


Hi Rainer,

I have been playing around with mod_rewrite, but as far as I can tell 
the rewrite is done before the jkmount. So I can get this wonderful url 
to be rewritten to the actual name of the web application, but since the 
old and the new versions have the same name it will not work.
For a moment I thought it might have something to do with the forwarding 
rules of mod_jk, but as far as I can tell the standard option is 
ForwardURIProxy which means it sends the rewritten rule to tomcat 
instead of the original one.


It would be wonderful if there would exist something to manipulate the 
url after is being forwarded with jkmount (or anything else that could 
help me get the results needed :) )

JkMount /web1|/* oldworker
JkMount /?*/web1|/* newworker

? matches one character, so the second rule won't match /web1/..., 
except for /web1/.../web1/...


The | character is a shortcut form for 2 rules in one:

JkMount /web1|/* oldworker

is equivalent to

JkMount /web1 oldworker
JkMount /web1/* oldworker

2) Rewrite request to remove /something before forwarding

Have a look at mod_rewrite. With mod_rewrite you can change the URL 
with a pattern based syntax. In order to forward the changed URL and 
not the original URL through mod_jk, you need to also set the pass 
through flag [PT] in mod_rewrite


Now the only thing I'm not sure at the moment is, if in case you 
rewrite the URL via mod_rewrite, the JkMounts are handeled before the 
rewrite (then this should work) or after (then it would obvisouly not).


Play around a bit with the ideas, set JkLogLevel to debug and use a 
RewriteLog with a high level, so you can follow the URL manipulation 
and mapping in the log.


If rewrite is done before JkMount, we'll have another solution :)


Any help would be welcome.
With kind regards,
Edwin

Re: Busyness Method and others...

2008-01-09 Thread Mohan2005


Hello Rainer;

Thanks again for taking the time and for the information.

if I quote you 

Who told you that? cping/cpong have nothing to do with load decisions. 
They only help in deciding, if a worker is in error status or not. Load 
is distributed between all nodes that are not in error. To which of 
those nodes a request goes is not decided by cping cpong.



But the million dollar question :-) is , if cping,cpong does not determine a
nodes HEALTH OR LOAD as you put it, how is the LOAD on a node determined
(what is used to monitor the health/load of nodes) technically by the
methods please?

Thanks and Best Regards

 The documentation says the following on the Busyness Method...

 If set to B[usyness] the balancer will pick the worker with the lowest

 This number is divided by the workers lbfactor, and the lowest value

 request take a long time to process, like for a download application.

 What is defined as take a long time, is it 30 sec, 40 sec, or more ?
 
 Let us rephrase this. Busyness is especially useful, if the number of 
 parallel requests you can handle is your limiting factor. Suppose you 
 need to handle very high concurrency, like e.g. 10.000 parallel 
 requests. Then you might come close to how many connections your 
 components (OS, web server, Tomcat, etc.) can handle and you need to 
 balance with respect to the expensive ressource connections instead of 
 CPU etc.
 
 Now how does parallelity relate to long running requests?
 
 Parallelity = Throughput * ResponseTime
 
 So given some fixed throughput, parallelity grows proportional to 
 reponse times. Talking about long response times is thus a simplified 
 rephrasing of talking about high concurrency.
 
 If you have 10 request per second (not a high load), but the response 
 time is 5 minutes, then you will end up with about 3.000 parallel 
 requests and this could be a good scenario for busyness method.
 
 and
 from the clarifications I have got from this forum, the nodes load is
 determined by it network latency using cping and cping. These I believe
 are

 used by all load-balancer methods to determine a nodes health. So
 checking
 the Requested hits (Acc in jkmanager) or Busy (Busy in jkmanager) or the
 Traffic are just checking the counters of a node that is more active than
 the other nodes. 
 
 Essentially what all these methods does is check a node's health by
 cping,
 cping (Network latency) , and if it responds in good time, then check
 either
 
 yes
 
 the 'Acc', 'Busy' or 'Traffic' counters and send to the node with least
 'Acc' if 'Request' method is used or Busy if 'Busy' method is used or
 Bytes IN/OUT if Traffic method is used.
 
 yes
 
 
 Is this summary of mod_jk in non-technical perspective accurate ??

ISAPI redirector log file not being written

2008-01-09 Thread pmarchwiak


Isapi_redirect.dll is not writing to its log file. I have Tomcat 5.5
installed on a Windows Server 2003 box and I am using the ISAPI redirector
to redirect some requests from IIS. I am using the isapi_redirect.properties
file for my configuration (as opposed to the registry settings) and my
worker properties and worker mount file are being read just fine. Is there a
permissions setting that I am missing? I have allowed full control for the
user IUSR_MACHINE_NAME on this file and it makes no difference. Does
anyone have any ideas about what could be wrong here? Thanks.

Re: tomcat5.5, balancer

2008-01-09 Thread Julio Cesar Leiva


Hi all


When we introduce load balancing and a 2nd tomcat worker, the time
to service client requests is not balanced. Some clients are serviced as 
above,

but others may take 10, 20, 30 seconds or more. Eventually, clients timeout
and sessions are lost.

We ran our test over night with just 20 clients. All requests were serviced
evenly and we experienced no timeouts. However, the attached jkstatus
page shows some interesting results. The 'Busy' and 'Max' values for
the two workers are vastly different. For worker1, these values just
keep incrementing. Also, worker2 has serviced way more requests.
The 'Busy' and 'Max Busy' numbers in the other table keep growing
as well. Is this behaviour normal? or does this point to a problem
somewhere in the configuration?

As we add more clients, the time it takes to service requests gets more and
more imbalanced. Some requests get serviced in  1 second, others can
take 20 or 30 seconds. The more clients we add, the longer it takes for
some requests to get serviced.

We are using apache 2.26, mod_jk 1.2.26 and tomcat 6.0.14 , JRE 1.5_06-b05
Apache and worker1 are  on the same box.  worker2 is in a different box



We are relly new on this(balancer), as you can see below we were using 
tomcat 5.5.20 , apache 2.2.0 and mod_jk 1.2.25 so we updated them all , 
but still same problems




Thanks a lot for your help

method T (Traffic) does only make sense, if you are bandwidth limited

Maybe a little simpler, if you omit the trailing '*', thus mapping the 
exact URL /jkmanager/.



JkMount /jkmanager/* jkstatus
# Enable the JK manager access from localhost only
!-- Location /jkmanager/



You don't need the next line, because you already defined this mount.


 JkMount jkstatus

connectionTimeout=60 would be a good fit to the 600 in your jk

2000 Threads is a lot, are you sure, that your OS can create that many

Re: Forwarding with jkmount


Edwin Walsh wrote:

Hi Rainer,

I have been playing around with mod_rewrite, but as far as I can tell 
the rewrite is done before the jkmount. So I can get this wonderful url 
to be rewritten to the actual name of the web application, but since the 
old and the new versions have the same name it will not work.
For a moment I thought it might have something to do with the forwarding 
rules of mod_jk, but as far as I can tell the standard option is 
ForwardURIProxy which means it sends the rewritten rule to tomcat 
instead of the original one.


It would be wonderful if there would exist something to manipulate the 
url after is being forwarded with jkmount (or anything else that could 
help me get the results needed :) )


OK, then plan B:

mod_jk has a less known way of deciding which worker to use when 
forwarding requests. You can also put the name of the worker to use in 
an httpd environment variable. If no JkMount matches, mod_jk checks the 
value of this variable, and if set, it sends the request to the worker 
that has the same name as the value of the variable.


What's nice: mod_rewrite in httpd 2.2 is able to set environment variables.

So you can first have a rule, that takes the original URL and sets the 
name of the worker (old_worker vs. new_worker9 into the variable, and 
the next rule rewrites the URL (removing the /something).


See 'env|E=VAR:VAL' (set environment variable) in 
http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html.


For the name of the environment variable, it is JK_WORKER_NAME. You 
can even change the name of the variable, if you don't like it with the 
directive JkWorkerIndicator. For the details and an example see Using 
SetHandler and Environment Variables in

Hi,

First of all I would like to mention that this is my first post on 
this list, I hope that this question is posted in the right place. I 
have tried finding a solution for my problem, but it either doesn't 
exist, or my limited brain can't manage to figure out how to do it (I 
strongly hope it is the latter)


In fact the solution to the problem is non-trivial :)


The situation is the following:
Currently we have several web applications running on a Tomcat 6 
server. For the sake of this explanation I will call then web1 and web2.
I have apache set up to use jkmount to forward requests from the 
apache server to the tomcat server. The problem is that I can only 
get apache to forward things like www.esat.kuleuven.be/web1 and 
www.esat.kuleuven.be/web2.


I would like to be able to forward things like 
www.esat.kuleuven.be//somefancyname//web1 to the same application on 
the Tomcat server.


I know this is possible with ProxyPassReverse in apache, but I would 
like to be able to do this with jkmount so that I keep the 
possibility to easily jump to a backup server if the main server goes 
down (Tomcat crashes more often for us then the http server does).


To add to the problem, the web applications I am talking about are 
updates from earlier versions. We still have the older versions 
running on older versions of Tomcat and the forwarding rules of 
www.esat.kuleuven.be/web1 need to continue to point to the old server.


As far as I can tell using the location tag in the apache conf file 
will not help since it seems to me that jkmount takes that location 
as a parameter to forward to Tomcat. And since my application is 
called web1 and not somefancyname/web1 it cant find it in the web 
applications folder.


Using a subdomain in a virtualhost could probably fix the problem in 
a way that I could use /somefancyname/.esat.kuleuven.be/web1 for the 
new web application, but it is very unlikely that our system 
administrators will allow us to set up this subdomain. And even if 
they would it isn't really the url I was hoping for.


So in sumary, what I would like is 2 types of links:
www.esat.kuleuven.be/web1 to point to the older web application
www.esat.kuleuven.be//somefancyname//web1 to point to the new web 
application (both have the same name but are on a different tomcat 
server)


I think the solution should have 2 ingredients:

1) Make sure, that /web/ and /something/web match different JkMounts

JkMount /web1|/* oldworker
JkMount /?*/web1|/* newworker

? matches one character, so the second rule won't match /web1/..., 
except for /web1/.../web1/...


The | character is a shortcut form for 2 rules in one:

JkMount /web1|/* oldworker

is equivalent to

JkMount /web1 oldworker
JkMount /web1/* oldworker

2) Rewrite request to remove /something before forwarding

Have a look at mod_rewrite. With mod_rewrite you can change the URL

Balancing itself choses the worker with the lowest lb_value. How do we 
get an lb_value. I cite myself:

- method Request (default): increase the load value of a worker by one 
for each request send to the worker and divide by two all load values 
every now and then (app. once a minute). So the load value is the 
comulative number of requests handled by the worker with a envelope 
curve that counts older requests less than more recent ones. This method 
tries to keep total work balanced.


- method Session: the same as Request, but do only count a request, if 
it didn't contain a session cookie or URL encoded session. It is not the 
same as actually knowing how many sessions each backend has.


- method Busyness: load value is the number of requests currently 
being processed by a worker. For example when load is low, most or all 
workers will have load value 0. This method tries to keep concurrency 
balanced. It will not be good in balancing total work.

and finally (I forgot in the original mail)

- method Traffic: Like request, but for each request do not increment 
by one, instead increment by the number of bytes transferred to the 
backend for the request plus receuved from the backend with the response.



methods please?

Let us rephrase this. Busyness is especially useful, if the number of 
parallel requests you can handle is your limiting factor. Suppose you 
need to handle very high concurrency, like e.g. 10.000 parallel 
requests. Then you might come close to how many connections your 
components (OS, web server, Tomcat, etc.) can handle and you need to 
balance with respect to the expensive ressource connections instead of 
CPU etc.


Now how does parallelity relate to long running requests?

Parallelity = Throughput * ResponseTime

So given some fixed throughput, parallelity grows proportional to 
reponse times. Talking about long response times is thus a simplified 
rephrasing of talking about high concurrency.


If you have 10 request per second (not a high load), but the response 
time is 5 minutes, then you will end up with about 3.000 parallel 
requests and this could be a good scenario for busyness method.

In Joes case CICS seems to get used as an HTTP client, not an HTTP
server.

Nevertheless the server page you found includes a link to

http://publib.boulder.ibm.com/infocenter/cicsts/v3r1/topic/com.ibm.cics.
ts31.doc/dfhtl/topics/dfhtl_cwschunking.htm

that contains the following information:

===
When CICS as an HTTP client receives a chunked message as a response to
an application program's request, the chunks are also assembled before
being passed to the application program as an entity body, and any
trailing headers can be read using the HTTP header commands. You can
specify how long the application will wait to receive the response,
using the RTIMOUT attribute of the transaction profile definition for
the transaction ID that relates to the application program.
===

So it seems, that CICS 3.1 does support chunked encoding when reading an
HTTP response.

So using either apache httpd or the chunked-encoding enabled variant of
the isapi redirector could indeed be the solution.

Rainer

Re: looking for sample MBean code for tomcat 6

2008-01-09 Thread Frank Z

Hi Peter,
Thanks for sending the link.  I guess what my real question was:

how would I get TC to 'declaratively' instantiate my MBeans ?

From the example,  most of them has a main() method to instantiate and 
register the MBeans to the platform MBean Server.  What would you recommend 
for TC , a servlet that loads on startup and within the init method it would 
create and register the MBeans?

I am porting my MBeans from JBoss (embedding TC) and JBoss provides a 
declarative method do so without the needs of a servlet.  It is done by 
creating a service archive (e.g.   myservice.sar - containing a 
jboss-service.xml [similar to mbeans-descriptor.xml] that declares the MBeans). 
 The JBoss container would then instantiate the MBeans via the MBean's start() 
method.


public class Main { 
public static void main(String[] args) throws Exception { 
   MBeanServer mbs = ManagementFactory.getPlatformMBeanServer(); 
   ObjectName name = new ObjectName(com.example.mbeans:type=Hello); 
   Hello mbean = new Hello(); 
   mbs.registerMBean(mbean, name); 
   System.out.println(Waiting forever...); 
  Thread.sleep(Long.MAX_VALUE); 
   } 
} 

Thanks
Frank.

RE: Why use a Web Server over Tomcat?

 From: Martin Gainty [mailto:[EMAIL PROTECTED] 
 Subject: Re: Why use a Web Server over Tomcat?

 Apache is considerably lighter on its feet to serve static 
 pages and images quicker than TC

While that was true several years ago, the current versions of Tomcat
achieve virtually identical performance when delivering static content.
Adding the overhead of another comm node for every request will hurt
performance, not enhance it.  Others have presented valid reasons for
using httpd, but performance isn't one of them.

Re: tomcat5.5, balancer

2008-01-09 Thread Gabe Wong


Julio,

Double check your httpd.conf to make sure there isn't multiple 
MaxClients entries that way you are certain
the one being used us indeed the entry included in the snippet you had 
shared with us.

Apache does not throw an error for Duplicate MaxClients entries.

Hi all


When we introduce load balancing and a 2nd tomcat worker, the time
to service client requests is not balanced. Some clients are serviced 
as above,
but others may take 10, 20, 30 seconds or more. Eventually, clients 
timeout

and sessions are lost.

We ran our test over night with just 20 clients. All requests were 
serviced

evenly and we experienced no timeouts. However, the attached jkstatus
page shows some interesting results. The 'Busy' and 'Max' values for
the two workers are vastly different. For worker1, these values just
keep incrementing. Also, worker2 has serviced way more requests.
The 'Busy' and 'Max Busy' numbers in the other table keep growing
as well. Is this behaviour normal? or does this point to a problem
somewhere in the configuration?

As we add more clients, the time it takes to service requests gets 
more and

more imbalanced. Some requests get serviced in  1 second, others can
take 20 or 30 seconds. The more clients we add, the longer it takes for
some requests to get serviced.

We are using apache 2.26, mod_jk 1.2.26 and tomcat 6.0.14 , JRE 
1.5_06-b05

Apache and worker1 are  on the same box.  worker2 is in a different box



We are relly new on this(balancer), as you can see below we were using 
tomcat 5.5.20 , apache 2.2.0 and mod_jk 1.2.25 so we updated them all 
, but still same problems




Thanks a lot for your help

Maybe a little simpler, if you omit the trailing '*', thus mapping 
the exact URL /jkmanager/.



JkMount /jkmanager/* jkstatus
# Enable the JK manager access from localhost only

You don't need the next line, because you already defined this mount.


 JkMount jkstatus

response.sendRedirect() failing mysteriously in struts application

2008-01-09 Thread Thomas Okken


Hi all,

I'm running into a problem in a struts application I'm working on.
In my struts-config.xml, I have this action-mapping:

  action path=/register
  scope=session
  name=RegistrationForm
  type=com.foo.RegistrationAction
  forward name=success path=/index.jsp redirect=true/
  forward name=failure path=/register.jsp redirect=true/
  /action

The RegistrationAction.execute() method takes several request parameters 
and uses them to create an account; when this is successful, it returns 
mapping.findForward(success), and otherwise, it returns 
mapping.findForward(failure).
For reasons I have not been able to determine, the redirection often 
fails. RegistrationAction.execute() will run successfully, the 
mapping.findForward() succeeds and finds the correct forward, which is 
then returned -- but an exception is thrown while the redirect is sent 
to the client. This is the full log output:

I understand that the second exception happens because, after sending a 
redirect, it is no longer possible to forward to the error page, but 
what is a complete mystery to me is why the first exception occurs.
RegistrationAction.execute() never touches the response, so struts 
should have no problem sending the redirect to /index.jsp (or back to 
/register.jsp, in the case of failure).
This exception does not happen consistently. Sometimes it does, 
sometimes it doesn't, with no

Re: response.sendRedirect() failing mysteriously in struts application

2008-01-09 Thread David Delbecq

The illegalStateException while sendRedirect happens because some 
content has already been submitted to client, thus the http code (OK) 
was already send and it's too late to change headers. Check your action 
don't do make output in the action.

Re: looking for sample MBean code for tomcat 6

Hi Frank, I played with this a long time ago, and I've completely forgotten 
what I did.
When it comes to monitoring servlets (own code) I came to the conclusion 
that its very hard to top a web server and an admin web page behind a 
password... but ok thats why I didnt persue it.


But there were 2 links in particular that I found very useful...
http://oss.wxnet.org/mbeans.html
which talks about general tomcat config your question is in there, the 
Mbean starts with a context listener.


and this...
http://www.netbeans.org/kb/articles/jmx-tutorial.html
which is a JMX plug-in for NB... makes testing and just getting the formats 
right easy.


and then on tomcat I vaguely remember having to set up DJava command lines 
so the TC would expose a port to Jconsole...


I dont remember seeing XML config to explicitly start a Mbean, I remember 
seeing that EJB containers tend to automate all this for you but servlet 
containers tend to be a little more manual.


Anyway I think armed with those tools, you'll be on your way.
I rember seeing it work on TC 5.5 but I dont think much changes other than 
the location of common/lib


Have fun





hello,
I am looking some sample MBean code for TC 6.0..  I was able to model some 
code after the source code (e.g.  MemoryUserDatabaseMBean.java in the 
org.apache.catalina.users. package) .


I was also able to create the mbeans-descriptor.xml

One question that I have is that even though the code compiled and 
deployed TC, i am not able to see my custom MBean via JConsole .


Are there additional things needed to get the MBean registered properly in 
TC?


Thanks in advance.

mod_jk and Host matches server name

2008-01-09 Thread Dmitry Beransky

I've seen many references to this problem, but since the message is an
umbrella to many possible problems, nothing of what I've read so far
offers a solution for my particular symptoms.

In the back I've got Tomcat 5.5.23 with default configuration:
   1. default host is localhost
   2. HTTP connector on 8080
   3. AJP connector on 8009

   After reading a message, I also added an alias to Host just to be sure.

   the application is deployed from a war into the default context
with ROOT.xml descriptor

On the front, I have Apache 2.2.4 with mod_jk 1.2.26 built from source
(I needed a 64 bit version that would work with apache 2.2.4)

Now, here are the symptoms:

- Connecting to tomcat directly on the localhost interface:  gets content
- Connecting to tomcat directly on eth0:gets content
- Connecting via mod_jk with worker.host=localhost:  400 No
Host matches server name
- Connecting via mod_jk with worker.host=10.10.1.12:400 No
Host matches server name

(The details of these tests are below)

Any ideas what's going on here?

Thanks
Dmitry

I go the expected results, ie, 'Hello(2)' and 'Hello'. Then I shutdown
tomcat and restarted it.
And when i tried to access those 2 urls again, I got the above error.

(Actually I had the same web.xml before except that it didnt have the
/classes in front in the
url-pattern. I was able to access it by the same url - without the /classes
- and then the next day
when started tomcat and tried to access it, it didnt work, same error.)

In this example, cucoweb is the context root, correct ? Shouldn't the
url-pattern be relative to the
context root ? Thats how I have it now, I think.

Would adding my webapp directory, ie cucoweb/classes, to my CLASSPATH help ?

I'm in ubuntu, when I do echo $CLASSPATH, I get :

I havent tried this yet because doing this is kind of tricky in ubuntu. (You
have etc/environment and
bash.bashrc, for ex.) But if I try that and it works I will post about it. I
suspect its something else,
though, because it worked once, before restarting tomcat, thats why I'm
posting here first.
Any info, even educated guesses, would be greatly appreciated. Thanks in

Re: Why use a Web Server over Tomcat?

2008-01-09 Thread David Smith

In my CISSP training, we covered the possiblity of putting a web server 
in between two firewalls.  The outer one cleans the course junk out of 
the data stream like denial of service attacks, web server compromise 
attackes, malformed packets, as well as closing down server services 
that should be available to the company, but not the public.  The inner 
one is more fine grained possibly protecting company data assets from 
disclosure or blocking unapproved websites from being accessed by employees.


Just trying to say there is a business case for two firewalls -- it has 
more to do with protecting company assets than protecting the web server.

What do you mean? If you have a Tomcat inside a DMZ, usually we have one
firewall, that separates internet from intranet, i.e., the firewall filters
requests that comes from de outside. Isn't that?

One reason for doing this, is again not whether IIS or APACHE is better 
although APACHE on linux in the
hands of a guru is very good, its because Tomcat carries clear text 
passwords, so if a hacker did
get at the machine, they would probably see the Active X LDAP master 
password, 
   



I don't understand this comment at all. 'Passwords' in tomcat can be 
managed by a whole host of authentication schemes. I use SSL to protect 
access to the password on the net and MD5 encoded passwords in a 
database for user authentication and access control. It depends entirely 
upon how you configure your system.

What's in the logs?

 Then I shutdown tomcat and restarted it.

Are you using a real Tomcat, or some 3rd-party repackaged (i.e., broken)
version?

 Would adding my webapp directory, ie cucoweb/classes, to my 
 CLASSPATH help ?

Absolutely not.  Never, never add webapp libraries to the classpath.

 I'm in ubuntu, when I do echo $CLASSPATH, I get :
 .:/usr/lib/jvm/java-6-sun-1.6.0.00/lib:
 /usr/lib/jvm/java-6-sun-1.6.0.00/imq/lib/:
 /usr/lib/jvm/java-6-sun-1.6.0.00/jre/lib

Other than the current directory (.), none of that stuff should be on
the CLASSPATH variable.  In fact, it's best just to completely eliminate
the CLASSPATH variable - it causes a lot more trouble than it was ever
worth.

problem with data input

I hope I am able to explain this problem adequately.  If I have gaps in
my explanation let me know and I will attempt to clarify further.  I
know enough about Tomcat to be dangerous, as they say.  I hope you guys
might be able to help me so here goes.
 
We have a MySQL database that we input case information into using a web
based application written in Java and running in Apache Tomcat 5.1.5.15.
On Monday one of our users was attempting to input some data into a
specific section of the database but the data was not stored.  This is,
so far, only happening in this one specific area of data entry that
inputs data into a specific table in the database.  We receive well over
100 new court filings that occur every day.  We have multiple users
inputting data into the new cases and existing cases every day
throughout the day.  So most of the data input is operating normally.
It is just input into this one area that I am seeing problems.  It could
be there are other areas with problems but we just haven't seen them
yet.  Whatever the case may be though, at present it is this one area
where I am seeing the problem.
 
I have been able to log into the database using MySQL Query Browser
1.1.6 and insert the data into the appropriate field for that record in
the table.  When I input that data I can then log into the web
application, navigate to that case and see the entry showing up as I
just entered it.  However, if I try to alter that data from the web
application nothing happens.
 
I had attempted to send this to the thread earlier with attached copies
of two logs for Monday and for Tuesday.  I never was able to see my post
on the thread so I am resending in the belief that my attachments may
have been cause for the forum to block my post.  If I need to post logs
please let me know what is the best way to send my logs.
 
Can someone assist me with finding out what may be causing this problem
and give some idea of how to resolve it?
 
Thanks,
Steve

Messing with the classpath will bring you nothing but pain and misery.
I would strongly recommend you leave it alone.

Also the servlet mappings are relative to the context so your good on
that front as well.

Are there any messages in your tomcat logs regarding the request? Are
you sure the webapp is running after you restart tomcat?

Subject: How Do I do (Can I do) Apache like redirects in Tomcat

Hi,

I would like to setup an HTTPS connector in Tomcat (v 5.5.23) that 
listens on port 28080.  That part's easy enough and there is already a 
certificate installed. 

Here's the part I'm having trouble with.  Whenever a browser send a GET

request to that port, I need to return a redirect to an entirely 
different server (different IP, etc) listening on port 28443.  I cannot

figure out anyway to do that.

Any ideas?

Thanks,

All of our users are still inputting data into the database using the

making it to the database server.

Hi all


When we introduce load balancing and a 2nd tomcat worker, the time
to service client requests is not balanced. Some clients are serviced 
as above,
but others may take 10, 20, 30 seconds or more. Eventually, clients 
timeout

and sessions are lost.

We ran our test over night with just 20 clients. All requests were 
serviced

evenly and we experienced no timeouts. However, the attached jkstatus
page shows some interesting results. The 'Busy' and 'Max' values for
the two workers are vastly different. For worker1, these values just
keep incrementing. Also, worker2 has serviced way more requests.
The 'Busy' and 'Max Busy' numbers in the other table keep growing
as well. Is this behaviour normal? or does this point to a problem
somewhere in the configuration?

As we add more clients, the time it takes to service requests gets 
more and

more imbalanced. Some requests get serviced in  1 second, others can
take 20 or 30 seconds. The more clients we add, the longer it takes for
some requests to get serviced.

We are using apache 2.26, mod_jk 1.2.26 and tomcat 6.0.14 , JRE 
1.5_06-b05

Apache and worker1 are  on the same box.  worker2 is in a different box



We are relly new on this(balancer), as you can see below we were

Thanks for sending the link.  I guess what my real question was:

how would I get TC to 'declaratively' instantiate my MBeans ?

From the example,  most of them has a main() method to instantiate

you recommend for TC , a servlet that loads on startup and within  
the init method it would create and register the MBeans?


I am porting my MBeans from JBoss (embedding TC) and JBoss provides  
a declarative method do so without the needs of a servlet.  It is  
done by creating a service archive (e.g.   myservice.sar -  
containing a jboss-service.xml [similar to mbeans-descriptor.xml]  
that declares the MBeans).  The JBoss container would then  
instantiate the MBeans via the MBean's start() method.



public class Main {
public static void main(String[] args) throws Exception {
   MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
   ObjectName name = new ObjectName

hello,
I am looking some sample MBean code for TC 6.0..  I was able to
model some code after the source code (e.g.
MemoryUserDatabaseMBean.java in the org.apache.catalina.users.
package) .

I was also able to create the mbeans-descriptor.xml

One question that I have is that even though the code compiled and
deployed TC, i am not able to see my custom MBean via JConsole .

Are there additional things needed to get the MBean registered
properly in TC?

Thanks in advance.

no debug property anymore, you can add

Re: web.xml configured correctly, but still getting '404...resource not found'


The guide I've been using for trying to set this up is the coreservlets book
by Marty Hall. He says set the 
classpath but the info there is for tomcat 4.  Are you saying I could just
get rid of the classpath 
environment variable entirely and it wouldn't make any difference ? (I did
set it to where the jvm is)

Here is the output of 2 of my tomcat logs :

If you are still looking for a solution:
There is a mismatch in your informations: you wrote, the keystore file would 
be located in your home directory but in the connector properties the 
keystore is referenced to be located at /user/machine/.keystore: are you 
aware of this difference?

Subject: tomcat 5.0.28 and SSL setup



My problem:  Port 8443 won't open.  But I can see port 8080.

Running Tomcat 5.0.28 on Mac OS 10.4.11 (no firewall yet).

I'm not using a self-assigned cert.  I created a CSR request, got my 
certs and have imported my certs in the following order using  Terminal. 
Everything I have researched says they have to be  installed in a 
particular order or the will not work.:


root - AddTrustExternalCARoot.crt
inter - UTNAddTrustServer_CA.crt
chain - NetworkSolutions_CA.crt
tomcat - mydomain.com.crt

(My keystore is located my user's home directory along with a folder  that 
has the certs in it.)


If I printcerts in Terminal, they look good to me compared to 
documentation and examples online. (howeverI'm a newbie.)


I have uncommented the connector port in the server.xml config.

Connector port=8443

Re: web.xml configured correctly, but still getting '404...resource not found'

2008-01-09 Thread David Smith

The tomcat startup script set's it's own classpath, ignoring the
environment set classpath. This has been the case since tomcat 4.
Tomcat 3 used to be a real headache because of the need to set a
classpath. If I remember correctly, tomcat 3.3 was the first version to
start offering a classloader architecture instead of making people work
the classpath.

Us the -n option of tail to get more log info like tail -n 100
catalina.out. See if you can get more of the log file since there
appears to be an error message in there further up.

It might make things better, certainly no worse.

That should never be done, under any circumstances.  The JVM knows where

Anything in the other log files?

Then I shutdown tomcat and restarted it.

Are you using a real Tomcat, or some 3rd-party repackaged (i.e., broken)
version?

Would adding my webapp directory, ie cucoweb/classes, to my

Absolutely not. Never, never add webapp libraries to the classpath.

I'm in ubuntu, when I do echo $CLASSPATH, I get :
.:/usr/lib/jvm/java-6-sun-1.6.0.00/lib:
/usr/lib/jvm/java-6-sun-1.6.0.00/imq/lib/:
/usr/lib/jvm/java-6-sun-1.6.0.00/jre/lib

Other than the current directory (.), none of that stuff should be on
the CLASSPATH variable. In fact, it's best just to completely eliminate
the CLASSPATH variable - it causes a lot more trouble than it was ever
worth.

 Who provides org.keel.clients?  You may need to be talking to them.

All of the Tomcat, Java, org.keel., etc. was developed in house by a guy
who is no longer here.  He created everything that is currently in
place.  I do not have access to him in order to address these issues so
that leaves me trying to explore this without really knowing what the
heck I am doing.  I know enough about this stuff to tell you things that
are probably not necessarily so (i.e. the version of Tomcat we are
running).  So basically you are talking to a novice in terms of all of
this.  Prior to Monday things were working without any glitches.  I do
not know what might have occurred Monday to change things but something
happened.  I do not have enough knowledge to know what I am seeing let
alone where to see it.

Ughhh.  So If there is a jar not loaded where should it be?  How do I
see it and/or go fix what may be broken in order to have it load
properly?   Why would it have not loaded on Monday when it appears it
was properly functioning prior to Monday?  Perhaps I am delving into
things I can only make worse with my inexperience.

I really do not know where to start.

Re: DataSource question

2008-01-09 Thread Eqbal

I am using lambdaprobe to monitor the datasource and
it shows that many maxActive connections for each
webapp deployed. So the total possible max connections
to the database would become maxActive times number of
webapps. But I would like to confirm that as I have
had occasional database connectivity errors and I was
suspecting if what lambdaprobe is showing isn't
correct and the total possible max connections to
database for all webapps combined is actually what is
specified in maxActive?
Anyone familiar with what I am talking about?

Thanks.

 Depending on how you configure the datasource it
 will be available for one
 or all webapps.
 
 The tomcat docs have a good explanation, here you
 got the link for tomcat
 5.5.

Re: web.xml configured correctly, but still getting '404...resource not found'


Check this out, I did 'touch web.xml' then hit reload in the browser window
and it worked. 
If I restart tomcat though, it probably wont work as before. 
Here's what my catalina.out looked like after that:

Not sure what the last line means.
Incidentally, when compiling the servlet, I had to use the classpath option,
ie javac -classpath to tell
javac where the servlet-api.jar is in tomcat. This seems weird to me that
the servlet interface is not in
the Java EE SDK, or if it is, it doesnt know where to find it.

So its saying Context startup failed, but I have no idea how to determine
what the 'previous errors' are.
FWIW, I am running tomcat through apache, not as a stand alone server.

Messing with the classpath will bring you nothing but pain and misery.  
I would strongly recommend you leave it alone.

Also the servlet mappings are relative to the context so your good on 
that front as well.

Are there any messages in your tomcat logs regarding the request?  Are 
you sure the webapp is running after you restart tomcat?

 So If there is a jar not loaded where should it be?

No one said there was a jar not being loaded - just that you have at
least one jar in WEB-INF/lib that should be removed.  Tomcat usually
figures out that it should ignore such duplications, but in the
interests of getting things as clean as possible so the real problem can
be uncovered, get rid of it.  If you find any others in WEB-INF/lib that
appear to be duplicates of ones in Tomcat's common/lib or server/lib
directories, the extra ones in WEB-INF/lib should be discarded as well
(ask first if you're not comfortable doing so on your own).

Tomcat Startup Hitting Webpage

2008-01-09 Thread Troy Davidson


Ok,  I'm sure I read this somewhere but can't find it.

I have a few apps that need to have threads started when Tomcat starts. 
 Isn't there a way to tell Tomcat to hit the addresses of these apps to 
start them up when Tomcat starts up?


I've searched everywhere and can't find anything.  Not finding anything 
has made me believe that Tomcat can't do this and it was wishful thinking.


Thanks.

Hi,

Is there a way to specify at runtime what worker the load-balancer 
should use first?


For some request, we can't use cookies so we pass the session id via 
the URL or via the query string. We then force the worker using 
RewriteRule and the JK_WORKER_NAME env var.
But then the request doesn't pass through the load-balancer anymore. 
So even if we stop that worker in the load-balancer, it will still 
receive the request instead of being redirected to another worker.


So is there a JK_LB_PREFERRED_WORKER kind of variable or equivalent 
that the load-balancer would use instead of the cookie?


Not directly, you could make use of the cookie and url encoding routing 
facilities of an lb though.


- Make sure the JSESSIONID gets deleted before and the new request 
doesn't contain a wrong ;jsessionid URL encoding
- Either use mod_headers to set a fake JSESSIONID Cookie header to the 
request


I can't set a fake cookie because we want to be able to set the cookie 
in the response if it was missing in the request (for instance, when 
switching from HTTPS (and secure cookies) to HTTP).



- Or use mod_rewrite and append a fake ;jsessionid=... URL encoding at 
the end of the URL (but before the query string).


Thanks, I didn't think about rewriting the request.



Let us know if this works :)


It does! Thanks! :)

Embedded Tomcat 5.5.17 error

2008-01-09 Thread sush0000


Hi All,

I am trying to develop a web application using EMBEDDED TOMCAT (5.5.17
version).
I am using standard function registWAR(contextPath, warPATH).
Inside this function, right after adding CONTEXT to HOST, I am getting this
exception.


Any help with this EXCEPTION and EMBEDDED TOMCAT (5.5.17) would be of great
help.

Thanks

Re: web.xml configured correctly, but still getting '404...resource not found'


Fixed. There was a parse error at context.xml, line 20, column 2. The
offending line:

 Context path= docBase=webapps/ROOT debug=0 reloadable=true
 crossContext=true
 /Context

I read somewhere that you were supposed to do this. Evidently bad info or
old info. 
Thanks for all the replies.

 Check this out, I did 'touch web.xml' then hit reload in the browser

 If I restart tomcat though, it probably wont work as before. 
 Here's what my catalina.out looked like after that:

 Not sure what the last line means.
 Incidentally, when compiling the servlet, I had to use the classpath
 option, ie javac -classpath to tell
 javac where the servlet-api.jar is in tomcat. This seems weird to me that
 the servlet interface is not in
 the Java EE SDK, or if it is, it doesnt know where to find it.

 start offering a classloader architecture instead of making people work 
 the classpath.
 
 Us the -n option of tail to get more log info like tail -n 100

 appears to be an error message in there further up.

Here is the output of 2 of my tomcat logs :

So its saying Context startup failed, but I have no idea how to determine
what the 'previous errors' are.
FWIW, I am running tomcat through apache, not as a stand alone server.

Messing with the classpath will bring you nothing but pain and misery.  
I would strongly recommend you leave it alone.

Also the servlet mappings are relative to the context so your good on 
that front as well.

Are there any messages in your tomcat logs regarding the request?  Are 
you sure the webapp is running after you restart tomcat?

  So If there is a jar not loaded where should it be?

 No one said there was a jar not being loaded - just that you 
 have at least one jar in WEB-INF/lib that should be removed.  
 Tomcat usually figures out that it should ignore such 
 duplications, but in the interests of getting things as clean 
 as possible so the real problem can be uncovered, get rid of 
 it.

Ok, I understand now.  I have removed servlet-api-2.3.jar from
/usr/local/tomcat/webapps/occa/WEB-INF/lib/.

  If you find any others in WEB-INF/lib that appear to be 
 duplicates of ones in Tomcat's common/lib or server/lib 
 directories, the extra ones in WEB-INF/lib should be 
 discarded as well (ask first if you're not comfortable doing 
 so on your own).

There are a tub load of jar files in that directory.  So I can look in
/usr/local/tomcat/common/lib and any duplicates of those in
/usr/local/tomcat/webapps/occa/WEB-INF/lib I will remove.  However, I do
not want to remove anything without knowing which ones first so I will
ask: Am I thinking about this correctly? 

I appreciate your time and efforts assisting me.  I am at the end of my
shift so I will not be able to reply until tomorrow to any other posts
on this but would appreciate the opportunity to continue with this
tomorrow.  I will look for any new posts first thing.

Thanks,
Steve

Yes.  Just remember this is getting rid of the noise so we can better
find the cause of the real problem, since I doubt this is it.

 There was a parse error at context.xml, line 20, column 2.

Which context.xml?  If it's in the webapp's META-INF directory or
conf/Catalina/[hostname]/[appname], it must not include the path or
docBase attributes.  Is that what you removed?

 I have a few apps that need to have threads started when

Read the servlet spec, especially the section on lifecycle listeners.
Make sure you terminate the threads when the webapp is shutting down.

RE: web.xml configured correctly, but still getting '404...resourcenot found'


This context.xml was the one in conf. All I did was copy the original
context.xml back.
I have 3 context.xmls :

/usr/local/tomcat/apache-tomcat-6.0.14/webapps/host-manager/META-INF/context.xml
/usr/local/tomcat/apache-tomcat-6.0.14/webapps/manager/META-INF/context.xml
/usr/local/tomcat/apache-tomcat-6.0.14/conf/context.xml

Just for my own info, what are these for and why do we need 3 ?  I don't
need an in depth answer, 
I'd just like to get a general idea of what context.xml does. I did read the
documentation on it a while
back, but didn't come away with a good understanding of it. Thanks for your
help.

 This context.xml was the one in conf.

That explains why you had problems.  The one in conf contains attributes
to be shared by *all* webapps; under no circumstances should it ever
contain any app-specific settings.

The other context.xml files define Tomcat-specific attributes for each
associated webapp that are needed for proper treatment of the webapp but
are not described in the servlet spec.  Each container handles this a
bit differently.

Once upon a time, Context elements had to be in server.xml, which
required restarting Tomcat if anything needed changing.  For the past
few years, Tomcat has made it possible to place Context elements in
webapp-specific locations, allowing changes with only a restart of the
particular webapp, not the whole container.  Consequently, the path and
docBase attributes are no longer appropriate in most instances.

The Context doc is here:
http://tomcat.apache.org/tomcat-6.0-doc/config/context.html
