preferred tomcat version

[mukesh]

Hi friends,

I am using Redhat Linux 7.0 and Apache web server (not tomcat). 

 

Which is the preferred version of tomcat I should use to add the
JSP/Servlet to my apache we server (and why)? And that tomcat version must
support mod_jk in order to connect it to apache (thankfully this has been
suggested by someone on this list)

 

Please advice.

 

Regards,

Mukesh

AW: Error: Io exception: Connection reset

[Tobias Meyer]

Maybe the user hit the "stop" button on the browser while downloading a page
or binary.

IIRC this will give you IOExceptions in your servlet when trying to push
more data in the "dead" connection.

It could also be your firewall, that times out connections which have not
been used for some time.
If you use tomcat connection pooling, try using 

validationQuery
select 1

in the ResourceParams of your jdbc connection definition in server.xml 
(see tomcat documentation for details)


Hth,
Tobias

There are two likely problems, but I don't know which one applies to you.

1) Since you are using 5.5.12, if you installed the libtcnative.dll with 
Tomcat, then you need to configure SSL via 
http://tomcat.apache.org/tomcat-5.5-doc/apr.html.  In particular, you need 
to extract the private-key into an OpenSSL format.  Alternatively, you can 
rename the dll for now, and work on just getting the Java Connector working.

2) You imported your cert into a different keystore file than the one that 
use used to generate the CSR.  Import the cert into the original one and you 
will be fine.  If you used OpenSSL to generate the CSR, than the easiest is 
to convert to a pkcs12 keystore as described above.  Alternatively, you can 
try using http://www.comu.de/docs/tomcat_ssl.htm.

Perhaps not in the Stub.  A little Googling came across this note at
Java Boutique
(http://javaboutique.internet.com/tutorials/Axis2-2/ses_man.html):

The scope must be defined in the wsdl file:

value must be request, session, or application.

Since I've never used Axis, I can't really be sure that this is
pertinent, but it certainly sounds related to your situation.

Thanks for the link ...
I think first I need to be able to hit the https://localhost:8443 before
going any further?  Once that is working ... then hopefully I can figure out
how to restrict certain pages.

Core is the primary Tomcat download.  Beware of the .exe version, since
it does not include the various scripts that a beginner should start
with; the .exe installs only as a Windows service.  Better to get the
.zip or .tar.gz, as appropriate - I believe they're identical other than
the archive format, but I haven't verified that lately.  You used to
have to use the GNU tar utility for the latter form, but I don't know if
that's still true.

Deployer is a utility application that supposedly simplifies webapp
deployment; can't say that I've ever used it.  You can read about it
here:
http://tomcat.apache.org/tomcat-5.5-doc/deployer-howto.html
at the bottom of the page.

Embedded is a Tomcat variation that lets you bury Tomcat inside another
app; JBoss uses this format.  It is not for use with Apache httpd, as an
earlier posting might have implied.  If you're going to front-end Tomcat
with httpd, use the core download.  (Tomcat performance in handling
static content is getting very close to that of httpd, so there are few
reasons to complicate your life by front-ending it these days.)

The admin webapp is quite useful for poking around inside Tomcat from a
web browser, so by all means pick that up.  Just unzip (or untar) into
the Tomcat installation directory, update the conf/tomcat-users.xml
file, and play.

The compatibility package is required if you're going to run Tomcat with
a 1.4 JRE or JDK.  Contains a couple of jars with classes for XML
processing that are standard with the 1.5 JRE, but have to be added on
to 1.4 environments.

The documentation download is what it is.

Re: SSL Certificate Beginner Question

[Scott Purcell]

Yes Thanks David,

I did add the "keystoreFile=XXX" and "keystorePass="xxx". But it still
hangs. Since I was on Windows I used a full path to the file.  I forgot
about the https://localhost:8443? Just
curious. I know when I asked for the cert, Verisign asked me for my dns
name, so maybe the simple localhost will not work and only the dns entry
will work. ...

Thanks much for your time.

Re: SSL Certificate Beginner Question

<-- Define a SSL Coyote HTTP/1.1 Connector on port 8443 -->

 


You probably want to add the following attributes to the Connector above:

keystoreFile="keys/tomcatkeys" keystorePass="123"

Obviously, make the keystoreFile point to the name of the Java keystore 
that you put your certificate inside, along with the password for that 
keystore.  I believe the base is $CATALINA_HOME if you use a relative 
pathname like above.


You'll also need to update your webapp's web.xml file with something 
like (that is, if you want Tomcat to enforce SSL on your webapp):


(after any servlet-mapping XML elements, before the session-config 
and/or welcome-file-list XML elements of web-app element in WEB-INF/web.xml)



 
   Entire site
   /*
   GET
   POST
 
 
   CONFIDENTIAL
 




Hope that helps...

Get More Logging

[Scott Purcell]

I posted earlier about having some issues trying to get SSL configured on my 
Tomcat 5.5.12. Anyway, I changed some settings in my server.xml for my 
keystore, and see no errors being thrown under the logs/ directory. I checked 
stdout, stderr, but see no errors. 

I know that if I am using the wrong keystore location (I intentionally put in a 
wrong path) that I should see something. But I do not. How can I get more or 
better logging so I can find errors in order to trace down my problems witht he 
SSL configuration?


Thanks

Re: SSL Certificate Beginner Question

[Scott Purcell]

Real helpful ... I searched on SRV.12 and it brought up a bunch of links
that have nothing to do with Tomcat  config of SSL.

I probably posted a lame request. Let me try again.

I have purchased a certificate via Verisign, and I have installed the
certificate into a keystore. I am running Windows XP and Tomcat 5.5.12.
I put the keystore and Cert.cer in the Tomcat/bin directory for organiation.
I read that the default is usually in the home directory where tomcat is
installed on Unix. But that is another OS.

I followed the docs here under Tomcat 5 SSL and ran across this:
http://tomcat.apache.org/tomcat-5.5-doc/ssl-howto.html


The final step is to configure your secure socket in the
$CATALINA_HOME/conf/server.xml file, where $CATALINA_HOME represents the
directory into which you installed Tomcat 5. An example  element
for an SSL connector is included in the default server.xml file installed
with Tomcat. It will look something like this:


 <-- Define a SSL Coyote HTTP/1.1 Connector on port 8443 -->






Anyway I uncommented this snippet from my Tomcat server.xml file and
restarted. But I cannot hit https://localhost:8443 like the read-me states.

I have checked all $TOMCAT_HOME/logs and see nothing. It just hangs when
trying to call it. I can hit http://localhost and all is happy. But the
certificate states it is coming from a certain URL. So I am not sure how
that all works.


I hope this may help someone feed me back some relevant information.

Scott

What OS are you wanting to install Tomcat on?
And did you want to just run Tomcat Standalone, or put it inside Apache?

In your apache httpd.conf, you set:

I remember workers.properties is  located in apache/conf/, the same

And, do you indicate the location of tomcat in workers.properties, such as

Re: Problems with Mod JK (Apache 2.052 and Tomcat 5.5.9)

[blueberry lake]

Since I am a new user of mod_jk, please correct me if I am wrong.

In your apache httpd.conf, you set:
 "JkWorkersFile "/var/tomcat/conf/workers.properties"
I remember workers.properties is  located in apache/conf/, the same
directory with httpd.conf..

And, do you indicate the location of tomcat in workers.properties, such as
workers.tomcat_home=/.../tomcat/?

confusion of tomcat downloading

[blueberry lake]

On page http://tomcat.apache.org/download-55.cgi, there are several choices
for tomcat 5.x, like core, deployer, embedded, admin web application, etc.,
can anyone explain berifly what their difference are?
Thanks.

web app to show session state for all server sessions

[John MccLain]

I want to write a webapp that, when a request is made, will display session
state ( a display of attributes and values within a session) for all
sessions running in a Tomcat server. I wish the display to be similar to the
folowing:
App
session
attribute = value


My question is, can this be done - querying other context sessions, and
would it be done with MBeans, or is there a better way? Can someone point me
to documentation on how to do something like this

Problems with Mod JK (Apache 2.052 and Tomcat 5.5.9)

[Luka Andrejasic]

Hello guys,

I am trying to figure this one out for weeks. Nothing seems to work and I am

Error: Io exception: Connection reset

[KUMAR, NANDA [AG-Contractor/1000]]

Very often we are getting Io Exception: Connection reset error. There is a
firewall between tomcat app server and DB server.
I wonder whether firewall is closing the connection or what could be the
reason. Please let me know how to get rid of this error. 

Thanks in advance.

Alias element in Tomcat 3.2.x virtual host configuration

[Mieke Banderas]

As far as I understand you write virtual host server configuration like
this with the Alias element like this:
"host.com" as an alias to virtual host www.host.com.

What's the syntax in Tomcat 3.2.x?

My virtual host looks like this now:

Re: Java databases as alternative to MySQL on OS X Server? (OT)

[Richard Schilling]

You might try a Java Data Objects implementation:

www.objectdb.com
java.sun.com/products/jdo/index.jsp


These are pure object databases, and are reasonably fast.  The Sun's 
reference implementation of JDO is not intended for production use but 
it's great as a development toolkit.

Ah - so it's a build script issue, not one with the Java source code or
a runtime determination.  Would it be possible to include 1.5 versions
of those two classes in the download?  (I realize it would complicate
the build script somewhat.)  Are these classes used for anything other
than CRL?

Shouldn't matter functionally, although the 1.5 javac may generate
slightly better code.

You have to be careful about what viewpoint you're using.  From a Java
programmer's perspective, as well as actual JVM implementation, what I
said is true (although I left out any discussion of volatility and
visibility of writes in a multi-CPU system).  From a hardware or JIT
implementer perspective, what you said is appropriate, since it applies
primarily to CPU pipelines and other low-level memory writers (not
threads per se), but isn't terribly relevant from a practical Java
programming perspective.  Essentially all high-performance systems have
operated with some variation of these considerations from day one, due
to the potential of asynchronous I/O modifying the instruction stream.
The introduction of write buffers into CPU pipelines twenty-odd years
ago really exacerbated the situation.

> Also please note that JSR-133, once implemented, supposedly makes the

Only for intra-thread actions; for inter-thread, ordering is specified
primarily with regards to entities marked volatile and synchronized
operations.

about

Actually, JSR 133 largely reflects what the 1.4 HotSpot JVM had already
implemented.  As you say, the jury is still out on whether all of the
low-level synch points have been covered.

The PowerPC instruction set includes lwarx and stwcx for this purpose.
If the JIT in the OS X JVM does not generate code to use these for
object synchronization, it would be seriously deficient compared to all
other commercial JVMs.  Without generating such code inline, any
multi-threaded interactions are bound to be horribly slow.

> Are you an MS-Windows programmer by any chance ?

Only when I can't avoid it.  Started working on multi-CPU systems in
1969, so I'm quite familiar with synchronization and data visibility
concerns.  35+ years of doing software and hardware design on a variety
of platforms, including several patents for various features of our
systems.  Currently responsible for (among other things) the JVM
implementation on our 36-bit ones-complement mainframes (and yes, our
JVM does pass all the compatibility tests).  So much for disregarding
multi-platform issues.

  A solution with the anchor tag would work the best if possible because 
the data is good, and the download is fast.

HTTP 404 error when mod_jk 1.2.15 connects apache 2.0.55 and tomcat 5.0.28 on unix

[blueberry lake]

(sorry if I  send this message twice,  I didn't get the first one)

Hi all,

I installed apache 2.0.55, tomcat 5.0.28, and mod_jk 1.2.15 on a
solaris 5.9unix machine.
Before I connected apache and tomcat, both of them work fine if I start them
up as seperate servers.
Mod_jk is complied from source code and mod_jk.so is copied to
apache/modules/


The connected system gives me the tomcat welcome page for URL
http://localhost:7888/
( I changed apache to listen to port 7888. ), which seems fine. The problem
is that when
I access the URLs like  http://localhost:7888/jsp-examples/, I got the
following error:
=
HTTP 404

type Status report

message /jsp-examples/

description The requested resource (/jsp-examples/) is not available.

Apache/Tomcat 5.0.28
==


For tomcat, I comment out the 8080 port (http) so that to make sure it stops
the http service and only handles the requests
on port 8009 from apache. That's the only modification I did in tomcat.

For apache, I add workers.properties file and edit httpd.conf, both  in
conf/ subdirectory.
The workers.properties is like:
==
workers.tomcat_home=/usr/local/jakarta-tomcat-5.0.28
workers.java_home=/usr/j2sdk1.4.2_03
ps=/
worker.list=worker1

worker.worker1.port=8009
worker.worker1.host=localhost
worker.worker1.type=ajp13
worker.worker1.lbfactor=50
==



The httpd.conf has the following modification:
===
#
Listen 7888

#
LoadModulejk_module  modules/mod_jk.so

#
#config of mod_jk
#
JkWorkersFile /usr/local/apache2.0.55/conf/workers.properties
JkLogFile /usr/local/jakarta-tomcat-5.0.28/logs/mod_jk.log
JkLogLevelinfo
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

#
JkMount  /*  worker1
JkMount  /*/*  worker1
JkMount  /*/*/*  worker1
JkMount  /*/*/*/*  worker1
#
# End of mod_jk


Also the log files seem don't give me much useful info, for example, the
mod_jk.log file has the following line:

RE: Tomcat suddenly not working

[Bachler, Elisabeth (Elisabeth)]

Thank you to everyone for your great help. "Someone" from my team, without
telling me, updated the jdk. Now, JAVA_HOME is pointing to the correct
directory and everything is working.
Once again, thank you

Actually, under /usr/java there is a readme file that says that the version
is 1.4.2!!
I have just found out that may be someone from my team has been changing
things
How can I find out if there is a new sdk version... and where it is? (can't
ask someone now!)

Are you sure you have your Java path's correct? This will occur if 
JAVA_HOME is set to, say a 1.4.2 release.

RE: web client running out of ports! (timeout exception)

[MW Janssen]

i had the same. The database connection pool was not right implemented so
each new connection was opened. What you can do is to set the time-out
shorter (in the registry, google it) and als to numbers of ports using (up
to 6 or something, also in registry, google it). But better is to find
out why so much connections (ports) will be created.

I'm sure you are - but it's the client's responsibility to reuse them; all
the server has to do is expect more traffic on the connection, which appears
to be what it's doing.

Only if you fail to read the instructions in RUNNING.txt and don't
install the rather tiny compatibility package.  TC 5.5 was compiled with
1.4 as the target, and is certainly not "packaged" with J2SE5.0 - that's
a separate download from your friendly neighborhood JVM vendor, not from
Apache.

RE: Tomcat suddenly not working

The JAVA_HOME variable points to /usr/java that seems to be the correct
thing.
How can I be sure?

You may think you're using JDK 1.5, but Tomcat doesn't seem to. :)

Check the docs and make sure (I think) JAVA_HOME is pointed to the right
place.

RE: How to test connection pooling

[Manisha Sathe]

Hi,

I tried with MSSQL/MySQL on Tomcat 4.1 / Tomcat 5. On
Tomcat 5 everything works great but on omcat 4 for
both databases I do not get pool  of connection. It
always gives one single connection and does not create
another if needed. 
I am stuck like anything, and want to use it rather
than going back to old method (JDBC call).

I completely reinstall tomcat 4.1 and tested. Is there
any workaround, setting which i can try ? Btw i am
using singleton class, i thought it may be causing
problem so tried w/o my singleton too.

Passing complete extract of my context xml. Pls guide
me.

Um, no it wasn't. It was built using 1.4. That is why the 5.0 specific 
stuff is missing.

Not necessarily. But it would create complications to maintain 1.4 
compatibility where there is 1.5 specific code. The 1.5 code is 
skipped if 1.4 is used to build.

Nope, it is that simple. There was a discussion about this on the
dev list recently. However, I would be wary of only compiling the 
"extra" classes. To be on the safe side, I would re-build the lot with 
1.5.

Are you sure you have your Java path's correct? This will occur if

HTTP 404 error when mod_jk 1.2.15 connects apache 2.0.55 and tomcat 5.0.28 on unix

[blueberry lake]

Hi all,

I installed apache 2.0.55, tomcat 5.0.28, and mod_jk 1.2.15 on a
solaris 5.9unix machine.
Before I connected apache and tomcat, both of them work fine if I start them
up as seperate servers.
Mod_jk is complied from source code and mod_jk.so is copied to
apache/modules/


The connected system gives me the tomcat welcome page for URL
http://localhost:7888/
( I changed apache to listen to port 7888. ), which seems fine. The problem
is that when
I access the URLs like  http://localhost:7888/jsp-examples/, I got the
following error:
=
HTTP 404

type Status report

message /jsp-examples/

description The requested resource (/jsp-examples/) is not available.

Apache/Tomcat 5.0.28
==


For tomcat, I comment out the 8080 port (http) so that to make sure it stops
the http service and only handles the requests
on port 8009 from apache. That's the only modification I did in tomcat.

For apache, I add workers.properties file and edit httpd.conf, both  in
conf/ subdirectory.
The workers.properties is like:
==
workers.tomcat_home=/usr/local/jakarta-tomcat-5.0.28
workers.java_home=/usr/j2sdk1.4.2_03
ps=/
worker.list=worker1

worker.worker1.port=8009
worker.worker1.host=localhost
worker.worker1.type=ajp13
worker.worker1.lbfactor=50
==



The httpd.conf has the following modification:
===
#
Listen 7888

#
LoadModulejk_module  modules/mod_jk.so

#
#config of mod_jk
#
JkWorkersFile /usr/local/apache2.0.55/conf/workers.properties
JkLogFile /usr/local/jakarta-tomcat-5.0.28/logs/mod_jk.log
JkLogLevelinfo
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
#
JkMount  /*  worker1
JkMount  /*/*  worker1
JkMount  /*/*/*  worker1
JkMount  /*/*/*/*  worker1
#
# End of mod_jk


Also the log files seem don't give me much useful info, for example, the
mod_jk.log file has the following line:
[Tue Nov 29 15:33:54 2005] worker1 [localhost] 0.089465

ANy suggestions are overwelcome!

Rather simplified and not accurate where accuracy would have caused me 
to get way off topic, but all in all not really incorrect.

Please read up on your Java memory model. What you describe is a nice 
abstraction that many Java developers have in their mind, but is 
technically not correct and can't be correct when you consider multiple 
processors, DMA, hyper-threading or even just plain old L2 CPU caches.

[http://www.cs.umd.edu/~pugh/java/memoryModel/jsr-133-faq.html]
[http://www.developer.com/java/article.php/951051]
[http://www-128.ibm.com/developerworks/library/j-jtp02244.html]

Also please note that JSR-133, once implemented, supposedly makes the 
whole discussion irrelevant as it forces read/write ordering. But 
AFAIK, only Sun's JVM 5.0 (1.5) implements it and I'm not sure about 
its correctness.

You are obviously disregarding the fact that Java is a multi-platform 
environment, and some platforms (notably the Mac OS-X which started the 
whole thread) does not provide such a mechanism. Are you an MS-Windows 
programmer by any chance ?

> No copying of local variable is ever

If it ever appeared that I was talking about 'local variables' when I 
wrote the word 'local' then I'm deeply sorry, and I here-by request 
that you please re-read my original post more carefully.
The word local in this case was used to denote the running thread's view 
on the shared variables, also knows as "thread local storage" (do look 
up that concept as well when you read about the Java memory mode, 
please).

You may think you're using JDK 1.5, but Tomcat doesn't seem to. :)

Check the docs and make sure (I think) JAVA_HOME is pointed to the right place.

RE: Certificate Revocation Lists in Tomcat 5.5

[Duan, Nick]

That's indeed good news.  I'd really like to know the result and
appreciate any details. 

Tomcat 5.5 supposed to run on JDK 1.5.  Why was it compiled with JDK
1.4?

Martin,

I have yet to try what you suggested, but if this is the case, I am 
grateful for your advice.  I had already got our web application up and 
running on stand alone Tomcat (5.5.12) when I ran into this issue. 
Realizing this, I was thinking that I would have to scrap my work and
start 
over figuring out how to run our web app with Tomcat integrated with
Apache 
HTTP server.  That option seems more labor intensive, as configuration
of 
Tomcat was a breeze (even using SSL).  Two questions (for anyone):

1) Is there any reason why running our web app under Tomcat is not as
good 
as running it under Tomcat/Apache HTTP server integrated?

2) With the solution proposed below, is it possible to point to more
than 
one CRL file?  We multiple from multiple agencies, and previously just

Java client does not re-use TCP/IP connections.

[Magyar, Bence]

Sorry,
  I'm quite new with all of this.  I've created a java client to my tomcat web 
service using the Java2WSDL2 utility and WSDL2Java utility.  Correct me if I'm 
wrong, I believe this is called the "stub" client model.  At any rate, my 
main() function in my client looks like:
   
  // get the web service...
   service = new WSDefinitionServiceLocator();
   
   // Now use the service to get a stub to the service
   ws = service.getMyWebService();
  
   Stub s = (Stub) ws;
   s.setMaintainSession(true);
   
  After this is set up, I can correctly call methods on my service such as 
   
  ws.Method1();
  ws.Method2();
   
  For each one of these invocations, my client creates a new TCP/IP connection 
to the service instead of reusing the existing one.  Am I missing some critical 
parameter 
  in my Stub class?  I'm not sure how else to configure the client.  If anyone 
could 
  point me in the right direction, it would be much appreciated. Thanks!
   
  B.M

I'm sure you are - but it's the client's responsibility to reuse them;
all the server has to do is expect more traffic on the connection, which
appears to be what it's doing.

RE: Client Authentication

[Dobson Paul L Contr 84 MSUG/GBMLBR]

Thanks for the additional insight into client authentication.

The smart card and IE are set up correctly to prompt for a valid
certificate.  I know this because that is how it works when I visit other
web sites on our network that has client authentication implimented.  I have
a feeling the problem I am having has something to do with Tomcat not
knowing what to validate clients against.  

Does Tomcat use the value in the keystoreFile property to determine what
certificates to validate client against?  If so, what entries should be in
the keystore? If not how do I let tomcat know that CA to validate against?

Below is the applicable part of my server.xml




Here is the content of the keystore being used for SSL from running keytool
-list.  Please let me know if something doesn't look right.
---
tomcat, Nov 4, 2005, keyEntry,
Certificate fingerprint (MD5):
FE:5A:8B:C9:95:72:85:2D:46:52:86:90:7A:98:B1:E2
mykey, Nov 28, 2005, trustedCertEntry,
Certificate fingerprint (MD5):
C9:0F:75:AA:61:F0:B2:8B:73:A9:2F:40:57:48:15:C1
---

mykey is what I want to validate clients against.

I guess what I am looking for are confiuration steps that I may have missed.

Thanks in advance for your help.

Client Authentication works as follows: You connect to the server, the
server gives you a list with valid certificates. IE looks if it has a
certificate in the list. The next step depends upon your IE settings. If
there is only one matching certificate and you set IE up to automtically
choose one the connection is established. If there are more you get a
window, where you can select the proper certificate. If there are none
you either get a "page cannot be displayed" message (automatic mode) or
you get a window with not certificate to choose.

So if you are using a smartcard you have to somehow tell IE that it
should take a certificate from a smartcard and not its internal
certificate store. I have no idea how this is all working with
smartcards though.

Markus

CRL support is present in Tomcat 5.5.12.

I am not an expert on Tomcat CRL support but what I
know is the following:

- You will need to recompile some of the
tomcat-util.jar classes with JDK 1.5 because Tomcat
5.5.12 was compiled with JDK 1.4. The classes to be
recompiled are:
org.apache.tomcat.util.net.jsse.JSSE15Factory and
org.apache.tomcat.util.net.jsse.JSSE15SocketFactory
classes.
- The crlFile property needs to be added inside your
SSL Connector in the server.xml file. The value is the
location of the CRL file on your system.

We've recently migrated our (SSL enabled) web

Is there any

I've had some traction on this problem.  If I remove the Loader element

Any ideas?

Hi again,
	Send a blank email to the following address as outlined at 
the bottom of each email:


[EMAIL PROTECTED]

As the subject line, use the text:

unsubscribe

	Then I suspect you need to reply to the confirmation addresss 
which sends a confirmation email to you which should complete your 
unsubscription.

Read this:

and then choose the appropriate spot in the Tomcat classloader hierarchy
for the jar.

I'm sure you are - but it's the client's responsibility to reuse them;
all the server has to do is expect more traffic on the connection, which
appears to be what it's doing.

RE: web client running out of ports! (timeout exception)

[Magyar, Bence]

Hi,
   
  You're right, it's probably something screwy with my client.  Not sure what 
it could be though.
   
  In looking at my Tomcat terminal, i see:
   
  INFO: Starting Coyote HTTP/1.1 on http-8080
   
  Shouldn't I be getting persistent, reusable connections as the default with 
HTTP/1.1?
   
  B.M

If I'm understanding the problem correctly, I don't see how changing
anything in the Tomcat configuation will help this anti-social client
behavior. Sounds like you need to fix your client to reuse connections
rather than creating a new one for each request.

I think you'll need to do more than that.  Tomcat has a variety of class
loaders, including one for each webapp, one for classes shared among all
webapps, and one for classes common to the webapps and Tomcat itself.
(This is in addition to the ones used by the JVM.)  See:
http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html
for details.  The picture there is quite illustrative.

This creates a tree of classloaders, and you will run into problems if
the same classes are present in more than one place along a particular
branch of the tree.  I've gotten burned too many times by the CLASSPATH
environment variable to use it anymore - I'd strongly suggest you delete
that variable and use explicit -cp settings where necessary.  This will
help to prevent any classes showing up under the wrong loader
inadvertently.

The gist of all this is that you don't want both j2ee.jar and
servlet-api.jar to be available to either your compilations or during
Tomcat execution.  It's possible that you might be able to replace
servlet-api.jar with j2ee.jar in Tomcat's common/lib, but I haven't
personally tried it.

RE: Help with session-timeout

[Rob Dickey]

Are there any other services involved (JDBC, etc.) that are referenced by or
in the session, or where the sessions are dependent? Just wondering why TC
threads are invalidating the session...

Another option to test is add a line of code in your login process (whatever
establishes the HttpSession object) and manually set the timeout with the
HttpSession.setMaxInactiveInterval() method.  I believe this method
overrides any descriptor settings.

Of course, having said all of that, your descriptors should work as you have
specified.  Perhaps the "multiple applications" or other service timeout
descriptors are influencing the session timeouts...I've seen stranger things
happen...you might find this link useful as a test of your TC session
timeout setup... http://www.jguru.com/faq/view.jsp?EID=127074

RE: How to test connection pooling

[Manisha Sathe]

Thanks for quick reply,

So you mean to say you did not get error for second
request and it created a new connection ? (But this is
for Oracle8i). Whether it means there is a problem for
MSSQL ?

mod_jk setting caused occassional 503 apache errors

[Mott Leroy]

I recently added some settings to my worker.properties which caused
apache to throw occassional "503" ("Service Temporarily Unavailable")
errors. I've commented out the setting and the errors do not occur.

The settings are related to timeouts (connect_timeout, prepost_timeout, 
and reply_timeout) placed on two load balanced workers. If a timeout 
occurs, it's supposed to failover to the other node. (note that one node 
is disabled, so it's fault tolerant, not truly load balanced)


The simple answer may be just to increase the timeout, but even so, it 
should be failing over, not timing out and throwing a 503 error. I've 
listed below my environment, a snippet of my worker.properties file, 
and the errors i saw in my mod_jk log. Any help and/or suggestions would 
be much appeciated! Thanks.

Re: HttpServlet not found?

[Martin Gainty]

yes if you're going to implement a simple servlet and you will not be 
implementing any (entity) beans 
(otherwise take servlet-api.jar off CLASSPATH and put back j2ee.jar to 
$J2EE_HOME\lib\j2ee.jar and place on CLASSPATH)

Using j2ee.jar with Tomcat usually results in much grief, since it
contains many classes that conflict with those supplied by Tomcat.
Suggest removing it from your system, or at least taking it out of your

Re: web.xml question

[Robert Palmer]

I was planning on doing this by having Apache handle the SSL and using 
its configuration file to differentiate between SSL'd areas of the site 
and non-SSL'd areas. Is this an option or should i rethink this?

Security constraints are only imposed on the incoming URL.

Long story short - you'll need to place the entire webapp in SSL. There
is no clean way to use declarative statements to force the login to be
SSL and the rest of the webapp be nonssl.

Re: JSP on apache

Mukesh,

I would use tomcat with Apache to accomplish this...

Or jetty.


the links are below:


To integrate the Tomcat server processes with the Apache HTTP server  
we need the mod_jk module, which implements the interface between  
Tomcat and Apache, combined with some small steps to configure Apache  
and Tomcat to our needs.

web client running out of ports! (timeout exception)

[Magyar, Bence]

Hello,  I noticed some strange behavior the other day while load testing my simple web service.  First, my environment:  I am running Apache Tomcat 5.5.12 with Axis 1.3 on an XP box.  I've used Java2WSDL and WSDL2Java to generate the necessary bindings.  I used the generated .wsdd file to deploy my service with an "Application" deployment scope and my Java client can call methods on the service the ease.  So far, so good.  By looking at the Axis SOAP monitor, all my messages seem to be getting through fine.  The trouble starts when I begin rapidly calling web service methods within a loop.  The first 3000 calls or so go through fine.  Then I get an Axis Fault: timeout exception.  See the attached is the stack trace.  Why is this happening?  I used the -netstat utility on the machine hosting the web service and noticed that -ea
 ch-
 method call is coming in on a different port!  Every time I call a method, my java client opens a new port!  On XP, the default port range goes from 1024-5000.  Worse yet, each port is in the TIME_WAIT state, meaning that it can't be re-used untill some specified timeout period.  After waiting for 10-20 seconds, Windows frees up all the ports and I can begin happily calling methods again.          I'm not sure why this is happening!  I thought the entire point of HTTP/1.1 was to persist connections.  If I make two calls to the same web service within X seconds of each other, shouldn't TCP/IP use the already established connection?  Especially a connection that is not in use and in the TIME_WAIT state?     I am fairly sure that I need to set the well-known TCP/IP parameter SO_REUSEADDR to true.  I know I can configure Tomcat with the server.xml file, but I could 
 not find
 anything related to this phenomena.  Instead, I see parameters relating to the keepalivetime, etc...My method calls will not be data intensive, but will be making many (thousands) method invocations at once.  Ideally I'd like to have one or two connections to the webservice and re-use them.  Does anyone have any idea how I could configure Tomcat/Axis to perform in this manner?        P.S.. In looking at some Apache source, I noticed that Apache sets the SO_REUSE_ADDR variable, but only in NON-win32 environments!  Is this feature not available in the Windows world?  Thanks for any leads!!!

Hi all.  I have a server with multiple applications running under Tomcat 5.5

In /conf/web.xml  is set to 30

In /webapps/myapp/WEB-INF/web.xml  is set to -1

Users are being timed out of their sessions after 30 minutes as opposed to 
never being timed out.  

Can anyone assist with this?  Any help would be greatly appreciated.

RE: How to test connection pooling

[Manisha Sathe]

Hi, 

After some testing on Tomcat 5 / Tomcat 4.1, i am
finding some strange behaviour.
I could figure out how to check number of conections
on MSSQL. It is Enterprise Manager -> Management ->
Current Processes - u have to refresh it now and then.

1)For Tomcat 5, it does create a pool of connections
at start depending on initial size. And it uses it
from those depending upon availability. I tested this
using some big loops.

2)But for Tomcat 4.1 - it does not create a pool of
conections but only ONE connection. I thought if
trafic increases it might add new connections to it.
So again tested with 2 requests and used a big loop so
that first request will make use of connection object
for sufficient time and will not release it. 

I was expecting second request should create new
connection in a pool, but it did not, it waited for
existing connection to become free and later it gave
error saying:

Error message

java.sql.SQLException: SQLException from connection
manager: org.apache.commons.dbcp.SQLNestedException:
Cannot get a connection, pool exhausted, cause:
Timeout waiting for idle object
--


Now whether it means that Tomcat 4.1 does not create
pooling at all ? Am i missing any settings ? For 4.1
am i suppose to use any different jars ?

I even tested the same for MySQL. The result is same.
Pls Pls help me, i am stuck like anything.

regards
Manisha

Tomcat installation: How do I specify an installation directory on the command line?

[Tyler Carpenter]

This regards Tomcat 5.x installation on a Windows system, using the Windows 
installer option.  I need to integrate Tomcat installation into my installation 
program, and I’d like to do so silently, but I also need to be able to specify 
the location of installation.I can silently install Tomcat using the “/S” 
parameter (jakarta-tomcat-5.0.28.exe /S), but this installs into the “Program 
Files\Apache Software Foundation\Tomcat 5.0” directory.  
I’ve tried the “/D” command line option (e.g., jakarta-tomcat-5.0.28.exe /S 
/D=c:\tomcat), but this makes no difference -- the installation still goes to 
the default path. 
Is there a document of the installation command line switches?  I couldn’t 
find anything in the documentation or in a variety of Google searches.  Any 
help is appreciated.  Thanks in advance.

Apache Server will not run JSP applications.  What you probably want to do
is run Tomcat either as a stand alone server in place of Apache Server or
set up Apache Server to send JSP requests through Tomcat.  Either way,
Tomcat will need to process the JSP requests.

Tomcat 4.1.31 error - method ()V not found

[Richard Mixon]

Hello,

I am moving a couple of small Java websites for a customer from one hosting
provider to another. Both are RedHat Linux machines with Tomcat 4.1.31 and
Java 1.4.2. On the new server I get the following error the first time I hit
a JSP page on the site.

...
- Root Cause -
java.lang.NoSuchMethodError: org.apache.commons.pool.impl.GenericObjectPool:

...

I have compared the class path and done diff's between the old tomcat and
the new. Other than the webapp directories are in a different location on
the new machine and I'm using a different port (9xxx versus 8xxx) all is the
same.

I have googled a bit in the list archives and in general and find the error
only mentioned once explicitly saying I've got a mismatched Commons jar
file. 

I have searched the machine for any stray instances of the DBCP jars, but
find nothing.

I've actually just copied over the Tomcat directory from the old server to
the new - but the error still occurs.

In case it really is DBCP related, I have attached a snipped from the
server.xml that defines on of the three hosts we are using.

Also, both old and new machines have Plesk hosting management software on
them and another installation of Tomcat 4.1 - but we are bypassing the use
of Plesk for these sites and are not running the Plesk version of Tomcat.

Any ideas? Help is much appreciated. 
 
Thanks - Richard

While in https - you'd need to reset the cookie (JSESSIONID) and not have the

Sharing session across http and https connections

[Chris Birch]

Hi,

I'm sure this has been solved and documented already but I can't find 
any information, if anyone can help me or point me in the right 
direction, I'd be very grateful.


I have an Apache->mod_jk->Tomcat installation.  I'm running two sites 
on Apache for the same domain but one is HTTP and the other is HTTPS.  
I'd like to be able to share a java user session across both the HTTP 
and HTTPS requests from a single user but a separate session is created 
for the secure and unsecure connection.


Does anyone know how to have a single session for a user regardless of 
whether they are connecting to the application via the secure or 
unsecure route?


Many Thanks,
Chris.

Client Authentication works as follows: You connect to the server, the
server gives you a list with valid certificates. IE looks if it has a
certificate in the list. The next step depends upon your IE settings. If
there is only one matching certificate and you set IE up to automtically
choose one the connection is established. If there are more you get a
window, where you can select the proper certificate. If there are none
you either get a "page cannot be displayed" message (automatic mode) or
you get a window with not certificate to choose.

So if you are using a smartcard you have to somehow tell IE that it
should take a certificate from a smartcard and not its internal
certificate store. I have no idea how this is all working with
smartcards though.

httpd-tomcat, a difficult cohabitation on port 8O

[Patrice Durosay]

Hello all,

without java nor tomcat experience, I'm now in charge of our web sites.

The first (tomcatweb) has been developped earlier by some one under 
tomcat, and works properly with the tomcat server on port 80 (instead of 
8080, question of authorisations).


The second (phpweb) has been developped recently by someone else in php 
and work well inside our lan with apache on port 8070 via an IP/port 
virtual host.


To be able to see it outside our lan, we defined several domain name 
aliases to the server's IP address and want httpd to be our server on 
port 80 to :

  serve virtual hosts by name (php-mysql)
  allow the connexion to our tomcatweb, and expresso for administrative 
purpose.


Actually, The tomcatweb is not available through httpd. Hope it will be 
possible.  
  
Apache is 2.0.46 from rpm & rpm-dev

tomcat is 5.0.27
I've just installed jk 1.2.15  from sources to replace the not working jk2.

Added in httpd.conf :
LoadModule jk_module  modules/mod_jk.so

 JkWorkersfile conf/workers2.properties
 JkLogFile logs/mod_jk.log
 #JkLogLevel info
 JkLogLevel trace
 JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

...
NameVirtualHost *:80

ServerName MyPhpWeb.MyDomain
DocumentRoot /PathTo/MyPhpWeb
ErrorLog logs/MyPhpWeb.log
TransferLog logs/MyPhpWeb_transfer.log
ServerAdmin [EMAIL PROTECTED]



I Tried to define a virtual host for the tomcatweb without success :
It drives to the page source of frame.jsp and do not execute it.
The .../ROOT/ contains both directories for applications expresso & 
MyTomcatWeb.


  ServerName MyTomcatWeb.MyDomain

RE: Certificate Revocation Lists in Tomcat 5.5

[Duan, Nick]

Tomcat currently doesn't support cert validation against CRL.  You may
want to use Apache's mod_ssl to do the CRL checking.  You will have to
use mod_jk to connect Apache web server with tomcat.

SSL is very computational intensive.  Use Apache's httpd to do the SSL
work is more efficient than to use Java-based tomcat.

Client Authentication

[Dobson Paul L Contr 84 MSUG/GBMLBR]

I am having a tough time finding information on implementing client
authentication.  When trying to access my site, I need the user to be
presented with a dialog box asking for a digital certificate.  The
certificate needs to be validated then bounced against a list of revoked
certificates, If it is valid and not revoked, the user should be allowed in
the site.  I have SSL implemented and have modified my server.xml, setting
clientAuth="true".  If I set it to true, I am quickly presented with the
explorer page that says:

 



The page cannot be displayed

 

The page you are looking for is currently unavailable. The Web site might be
experiencing technical difficulties, or you may need to adjust your browser
settings.

If I set clientAuth="want", I am let into the site without being prompted
for a certificate.

 

I think it is automatically behaving as if a client certificate is not
available without prompting for one  ( we are set up with ActiveCard smart
cards and readers at all work stations)

 

I am using Tomcat 5.0 with j2sdk1.4.2_04 on windows 2000 server with SP4

 

Here is my server.xml:



--





  

  

  







  

factory

org.apache.catalina.users.MemoryUserDatabaseFactory

  

  

pathname

conf/tomcat-users.xml

Any ideas  on how I can get this set up correctly?

Re: Singleton memory leak after redeploying.

[Lionel Farbos]

I said this to simplify
I agree that, in a large webapp, you need several loggers; each logger for a 
coherent system.
But you have to control your loggers...

In the initial question, it was like he had one logger for one class...

So, the right answer should be :
in log4j, there is no need for an additionnal method
because, if you control your logger(s), you can freed it(them) when the 
servlet.destroy() is invoked.

I hope it's better like this ... ;-)

how to find number of requests currently being processed?

[Brian O'Rourke]

Hello,

I'm trying to find out the number of requests currently being processed by
my Tomcat server using JMX. I am using Tomcat 5.5.12, where it is no longer
possible to find this out by counting the RequestProcessor beans returned by
a JMX query - I'm told this is because of a new feature (
http://issues.apache.org/bugzilla/show_bug.cgi?id=37692 ). Is there still
away to find information about current requests via JMX?

Thanks,
Brian P O'Rourke

Re: File Download not working for anchor tags

[Mike]

  I tried that setContentType and fileInputStream solution, but ran into 
two problems.  First, when I download an Excel file and load the downloaded 
file in Excel, it doesn't load in properly.  I'm guessing there's some data 
transfer problem.  Second, the first time I try to download, IE blocks the 
download.  If I download it a second time, it seems to work.


  A solution with the anchor tag would work the best if possible because 
the data is good, and the download is fast.

RE: heap size problems (speed) [2]

> Maybe this very approach has a design flaw when it comes to JAVA.

If it's expensive to generate / load that data and the app has tight
response time restrictions, and if there's enough RAM to keep the data
in main memory without paging, and if the heap is large enough to allow
other processing to take place, and if the map is set up so that there
are few collisions, then the map is a very sensible approach.

That's a lot of ifs.

I'd try the following:

- Check for paging traffic on your server.  Are other apps causing
Tomcat to be paged out, leading to expensive disk I/O when the map is
accessed?

- Follow Chuck's suggestion to check for garbage collection activity.
If possible, try increasing the Java heap size (and check for paging
activity on the server).

- Talk to your dev team to find out how well or badly the map is keyed.
A HashMap with a lot of entries can be slow if the hash for the key is
poor.  I'd expect to see high CPU usage *or* high paging activity if
this was the case, as the server will either spend a lot of its time
hashing or have to load a lot of pages from backing store to examine
them for hash keys.  Neither is pleasant.

Java HashMaps aren't inherently slow; something's poorly configured.
Those are a few guesses, no more than that.  I also suspect it's *not*
your CPU cache size.  Yes, going to RAM is slower than loading from a
processor cache line, but it's still a *lot* faster than retrieving a
row from the database.  I'd be looking elsewhere.  Intel have spent a
lot of money making people think that the CPU is the only contributor to
overall system speed; RAM and disk I/O speeds play a much larger part
these days.

I disagree, only the most trivial webapp needs one logger. A web

I think it's not a good idea to have a lot of logger objects in a webapp
:
In a webapp, you need only one logger.

Then, on the last servlet destroy, you can freed your logger with
logger=null; I think no other method is needed.
