But, you will run into problems if you use JNDIRealm with SSL (ldap with ssl 
- Container Managed Security)use mozilla-java sdk if you prefer to do 
this way.

Re: tomcat 5 - apache 2 - ldap

[Nili Adoram]

What about single sign-on for web applications and PHP?

Does tomcat delegate credentials back to Apache so Apache would not  
authenticate again?


Thanks

Hi,

I need to setup the following system:

   - Apache 2 (using mod_jk)

   - Form-based authentication (login page)

I still need to figure out the following:

   - Should Tomcat or Apache do ldap authentication ?

Thanks for the advice. I will try your suggestions. I
noticed that from the server status view of the tomcat
manager, I saw some thread with the status 'S' has the
time of '24685295'. Does it mean the thread has hang
there for more than 6 hours (close to 7 hours)?

Re: Tomcat 5 slow, it's in production, please help!

[Parsons Technical Services]

I think that would be the direction I would take.
If you need more proof:
Sniff the connection to the server to confirm the lack of available 
connections. So far it is pointing in that direction.

Another test you might do is create a connection from a known IP, close the 
browser and monitor the connection status. If it is hanging open then start 
digging.

I think you may also be experiencing  an issue of clickatosis. It occurs 
when the client doesn't think the page is responding quick enough and since 
more is better after 10 or 20 clicks they decide to wait or give up. Mean 
while for each click they cause a request which can bog things down. 
Wrapping this with the held connections you can get a scenario as such:

Client hits site.
No or slow response.
Clicks again. Or several times.
Often closes browser and tries over.
This creates a new connection request.
Snowballs from there.
Think about this, do you really get over a 100k users in six hours? Or even 
100k page requests? That's a lot of traffic. If the client machines abandons 
the connection before the server, then establishes a new one, it compound 
the problem.

Find a way to have the OS let Apache handle the connection timeout and get 
it down to a reasonable time.

Since you are inheriting this, there may be a reason that the connection 
timeout is set so high. If the original creator of this wanted the user to 
be able to sit on a page for a long time without losing the session and 
connection thus causing the user to have to re-authenticate. But then there 
is a trade off. which you are experiencing right now.

Get the time down until the complaint about having to re-login get too high 
or until the connection speed delay is acceptable.

It seems that, at least in most cases, the main menu
page after a login is loaded slow. After that other
pages are loaded pretty quick. Does that mean once a

should look more at the connection timeout at the OS

Re: Tomcat 5 slow, it's in production, please help!

[Parsons Technical Services]

127421 over what period of time?
Without a profile it is impossible to say if Tomcat can handle the load. But 
if the memory consumption and the CPU usage is low (as noted) it is fairly 
safe to say that Tomcat itself is not the bottle neck.

Quick question, why are you using Apache?
Also what is the time out for the connection in Apache?
Do you get this slow reaction if you are hitting Tomcat directly?
I may be repeating something that was covered because I have not been 
reading this thread in detail. So sorry if already asked and answered.

RE: Tomcat 5 slow, it's in production, please help!

[Tony]

As a wild guess
Browser drops the connection immediately without notice
After 5 minutes, tomcat decides to drop the connection
After 30 minutes or so, Solaris finally finishes dropping the connection.
Gives a strange meaning to "Keep-Alive" ;)

I am sorry, the box runs a Solaris 5.6 instead of 2.6
as I said before. But still you are probably right, it
would be better to get a new OS installed.

I didn't use ndd commands to set the TCP parameters.
So even though we have the session timeout set to 5
minutes at the tomcat level, that parameter is not
honored by the operating system?

But unsupported! Development of mod_jk1.x is going on, but not jk2. I
wouldn't advise anyone to select something uncontinued.
I set the session timeout time to 5 minutes, but

Check whether you session-timeout is really set correctly. You can set
the timeout in the default web.xml for all apps, but you could override
it in the webapps web.xml, too. Maybe there it's still set too high.

Yoo,

Yes switch to jk2 is faster!

set parameters in OPT_CATALINA with -server Xmx=? and Xms=?

Sorry values depend on your available memory on the server, parameters
could be different with your version, check or google for correct parameters,
should improve performance...

Another option could be your code, have a good look at it and try to optimize...

it sounds like the problem is caused by a large number of connections
dying holding things up.

I think some of the problem is at the OS level

You can set a session time at the tomcat level, but the default solaris TCP
timeouts are hours long.   I hope you used the ndd commands to set the TCP
parameters for short web sessions.

Also, Solaris 2.6 has a bad thread model and there are numerous patches
required to run it with  any recent Java 2 distributions.   To use the
1.4.xxx JVM would require about a dozen patches.

It would be way better to try to get Solaris 10 installed on this box  -- It
handles the ndd setting for you and is way faster on the same hardware.

There are certainly people here who understand this much better than I, but

ESTABLISHED these connections are doing something or are capable of 
doing
something

TIME WAIT   these connections are in the process of dying
CLOSE WAIT
FIN WAIT 2

They can't do anything useful but do occupy space until they are finally
gone.
If the browser just goes away and doesn't end the connection, the server has
to wait
for a while before ending it and waiting for responses that never come.

Re: Tomcat 5 slow, it's in production, please help!

[Jeffrey]

I use just mod_jk, not jk2 I believe. I do have
connectionTimeout="2" set to AJP connector in
server.xml

Is there any performance issues with jk? Should I
switch to jk2?

Thanks.

I actually have the reloadable set to true for my
webapps. I will change it to false. Thanks for the
remind. 

What optimal java parameters in your mind are
important ?

Thanks for taking look at this.

Re: Tomcat 5 slow, it's in production, please help!

[e]

What JK version do you use?  To quote Mladen:

"You are probably using prefork mpm, so there is no way to
control the number of connections to Tomcat in any way, trough
mod_jk. You can limit it only by setting MaxClients in the httpd.conf
to the maximum number desired.
Because of pre-forking mechanism each child process will eventually
establish a single connection to Tomcat, thus the number of connections
will rise from StartServers to MaxClients.

So there are two solutions for prefork.
1. Make maxThreads==MaxClients

Yoo,

Probably you already looked at it but :

1) Make sure not to use reloadable in context descriptions.
2) Start tomcat with optimal java parameters, concerning memory heap and stack
3) Make sure that connections to database are minimal, do requery if
answer is always the
same...

Good luck,

RE: Tomcat 5 slow, it's in production, please help!

What does "netstat -nt" show?
You may have enough connections going that old ones 
have to time out before you can establish a new one.

Subject: Tomcat 5 slow, it's in production, please help!


I have a apache/tomcat environment that has some
problems recently. The environment has the following:
1.  Apache 1.3
2.  Tomcat 5.0.28 (Max memory 384mb)
3.  JDK 1.4.2_06

My apache has MaxClient set to 256 (apache default).
The maxThread for tomcat is 500. The site is a
database driven site. 

It seems working fine when load is low. But when there
are more than 150 threads (from the sever status view
of the tomcat manager), it's response time is very
slow (5 - 10 minutes). I have tested the database
connections, they seem responding fairly well.

Interesting thing is that most of time the slow
response time only happens when a user login. Once the
user login and get the main menu page, the user will
get a good response time. Is it related to KeepAlive
connections. 

Another strange thing is that many threads always show
up in the server status view on the tomcat html
manager page even though I am sure the request has
gone (I tested this by making a request, then close
the browser).

My CPU usage is low when the slowdown is experienced
(Using the top command on this solaris box which has
old solaris operating system 2.6? with 1GB memory.

I set the session timeout time to 5 minutes, but in
the session view of tomcat manager, I see message "30
- <40 minutes:136 sessions". How a session that is
more than 30 minutes is still there. Maybe I don't
understand this message correctly.

Please advice. This is a production machine. Helps are
greatly appreciated.

Thanks.

Jeffrey.

Cool. I think other CAs have the same policy. How many
times can you revoke/renew with Verisign? Is it only
once?

BTW, it appears a DSA encrypted server will cause a
Netscape browser to throw an exception. Apparently
Netscape only handles RSA. There are probably other
clients & servers that will cause the same
incompatibility problem with a DSA encrypted server.
Since it is apparent, I guess, that it's too much
trouble to change the default keyalg to RSA in the
keytool command, the language should be much stronger
in the tomcat and ssl instructions to specify RSA
encryption.

Thanks for your input.

 You can revoke/renew with verisign for NO CHARGE within 30days.

Re: Tomcat 5 and SSL Configuration

[Lapo TIN]

and if I would like to store the certificate on a PKCS11 usb token ?
I did every steps:
1) generation of keypair on the usb token
"keytool -genkey -alias lapo -keystore NONE -storetype PKCS11 -keyalg 
"RSA" -validity 365"

2) request a certificate sign, it export a csr file on disk
"keytool -certreq -alias lapo -keystore NONE -storetype PKCS11 -file 
lapo_certreq.csr"

3) I give the file to the CA, CA signs with openssl, and generates the file 
lapo_cert.cer

4) then I would like to import the signed certificate on PKCS11 keystore to 
update it but it needs the root CA certificate in the PKCS11 Keystor to 
rebuild the chain.. in fact it says:
"keytool -import -alias lapo -keystore NONE -storetype PKCS11 -file 
lapo_cert.cer "
java error "impossibile stabilire la catena dalla risposta"

so first I try to import the CA certificate but it says  error again
"keytool -import -alias root -keystore NONE -storetype PKCS11 -file 
cacert.cer "
"trusted certificates may only be set by token initialization application"

I tried with many different model of usb token... same errors...
why ?!?!?

Here is the complete steps to generate a cert for the Tomcat Webserver. I 
am listing the commands that I used, your keystore directory _will_ vary.

keytool -genkey -keyalg RSA -alias tomcat –keystore 
password is "changeit"
then
keytool -certreq -keyalg RSA -alias tomcat –keystore 
 -file 

then once you receive the cert back from VERISIGN...
IF it's the first cert this server has had, you'll need to download a
chaincert from the following locations depending on who you purchase the
cert from:
For Verisign.com go to:
http://www.verisign.com/support/install/intermediate.html
For Trustcenter.de go to:
http://www.trustcenter.de/certservices/cacerts/en/en.htm#server
For Thawte.com go to:
http://www.thawte.com/certs/trustmap.html
Import the Chain Certificate into you keystore
keytool -import -alias root -keystore 
 -trustcacerts -file 


And finally import your new Certificate (It must be in X509 format):
keytool -import -alias tomcat -keystore 
 -trustcacerts -file

Re: Tomcat 5 and SSL Configuration

[Mark Thomas]

The following steps should work (although I have only ever done this 
using my own CA).

1. Create tomcat key in your own keystore
2. Create CSR
3. Submit CSR
4. Get response
5. Import CA's root cert to cacerts (%JAVA_HOME%\jre\lib\security\cacerts)
6. Import new cert to same keystore as 1 (use same alias & trustcacerts 
option)
7. Restart Tomcat

Yes, I do have a backup, but I should have mentioned

One of the first attempts ommitted step #5, but I had
the same result.
I used step #5 in an attempt to remove the old and
then insert the new. But that didn't work either.
One other thing that I noticed is that my previous
(expired) keystore had 2 certs in it one was a root
trusted cert entry and the tomcat key entry.
This time, in one of my initial attempts, the tomcat
alias was the only entry and it was the trusted cert
entry.
Does this have anything to do with the problem?

Re: Tomcat 5 + Apache SOAP?

[Mark Leone]

I agree with Trond. And since I wrote my reply rather quickly I want to 
make sure I'm clear. You only need to put in common/lib any jar files 
that both Tomcat and Axis need, which certainly does not include 
axis.jar and the other jars that come with the Axis distribution. I 
thought that maybe Axis needed access to the jar file that contains 
class HttpServlet, because I remember the installation instructions 
aaying that certian other jar files had to be on the classpath; but I 
checked and it doesn't look like axis needs to see HttpServlet.

Other than needing access to an XML parser, I don't think there's much 
the Axis server needs beyond what you already have in Tomcat. You should 
be able to just drop Axis in to Tomcat and have it run almost 
immediately, unless you have a non-standard configuration.

Maybe apache SOAP required it, but it seems doubtful. It seems like the 
reported error is more of a Tomcat problem. If you install Axis and get 
the same error, please report back to us.

Apache SOAP is the original apache SOAP implementation. I recommend you 
check out apache Axis, its successor. I have Axis 1.2 (formerly ran 1.1)

RE: tomcat 5 not deploying my war

[David Owens]

If you had a webapp there before, the problem may be that it cannot
undeploy the previous one because one of the jar or resource files is
locked.  If this is the case, you can turn on anti jar locking.

Hope this helps.

Forget the in-process.
The JNI connector is deprecated, and the reasons are many.
On of the major is that it can work only on WIN32 Apache and IIS.
Also bringing JVM in the same address space as web server, makes

There is a project called tomcat-native that will eventually bring

Re: Tomcat 5 on VPS service stops, FIXED.

[Stanczak Group]

Well surprise, surprise, I moved to a dedicated server and it works 
great now. It even uses less memory. Can someone say, Tomcat doesn't 
work on VPS's?

Re: Tomcat 5 on VPS service stops, still no luck.

[Stanczak Group]

Well I still can't seem to get this server running on my vps. They show 
that they have no limits that would keep me from running this. It's a RH 
9 machine and I put the "export LD_ASSUME_KERNEL=2.4.1" in the 
catalina.sh. I can't seem to even keep one running. I'm using 
jdk1.5.0_02. The only error I've found it here 
http://www.codedemons.net/pb/?show=2963 , but I don't see this error 
anymore. Does that have anything to do with the export of that variable? 
Anyway, I need serious help. I just can't seem to figure out why if 
won't stay running. I've got it where it will run for maybe an hour or 
so, but that's it. I think I'm going to start from scratch on it.

I'm having a strange issue with my Tomcat 5 server. I have two

them today. The systems are running RedHat. I'm at a loss trying to 
understand why these services just stop. One of them has a startup 
script so if the machine reboots it should start back up. I start the 
service with -Xmx64m -server and I'm using jdk 1.5.0_01. The history 
of this problem is that the last few days has been the worse, but it's 
had these shutdown issues from the start. One of the services has a 
cron that shuts down one of the services and erased the web app the 
copies a fresh one back, not sure that matters in this issue. If 
anyone has had this problem or has suggestions on solving it please 
let me know.

How could it not be started. I could access one of my servlets on it. Or

Ok, I've upped the -Xmx256m. Hope that works. I took out all the other

Re: Tomcat 5 on VPS service stops

[Stanczak Group]

That give me another question. Why on this RH Linux system when issuing 
the java command I get:

Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
That's why I put the -Xmx64m. Now I just changed it to this:
/usr/java/jdk1.5.0_02/bin/java -Xms48m -Xmx64m -Xss1m -server -Xincgc -Xrs
I thought when Tomcat ran out of ram it left a log entry? Hum, well, you 
think increasing ram will help? The thing is, both of these services are 
not used much.

That's not much memory for Tomcat to play with.  You might want to set 
-verbose:gc to see if you've fallen into a continuous GC mode, or possibly 
completely run out of memory.  Since Tomcat generates a lot of classes, it's 
pretty easy to exhaust the permanent generation space.

Thanks Wolfgang!

Still problems.

I downloaded from
http://cvs.apache.org/builds/jakarta-commons/nightly/commons-daemon/
the latest file:
commons-daemon-20050316.zip

autoconf worked fine.
./configure worked fine.
make failed with many errors.

How to fix this? Is it worth it? When is the next version coming out?

The errors are below.
I cross-posted to the commons-dev list because I used a nightly build.

Many thanks,

Re: Tomcat 5 - Apache2 & SSL with mod_proxy

[Robin Johnson]

I know this is a pretty old post, but I'll respond to it anyways so the 
solution shows up in the archives:

All you have to do is set scheme="https" and proxyPort="443" and the 
connector will properly redirect your connections using https.

HTH,
Robin
Kris Reese wrote:
Apache 2.0.52
Tomcat 5.5
openSSL 9.7e
I've successfully been able to install all three components with the 
following attributes:
I've successfully connected Tomcat to Apache via the mod_proxy 
module instead of using the JK2 connector
I've also successfully integrated openSSL into apache, so that I 
can have a secure connection via HTTPS.

So far, I'm only using the examples that shipped with Tomcat for 
testing purposes (i.e. /jsp-examples).

My problem is when I try to access /jsp-examples via HTTPS.  It always 
redirects back to port 80, thus I lose my secure connection.  I have a 
feeling this is due to the "proxyPort="80" as defined in server.xml.  
If I change proxyPort to 443, it appends :443 at the end of my URL 
instead of using https.  My ultimate goal is to have a webserver that 
only runs on port 443 which has a login.jsp page as the "index" page 
so people can login securely.

I've read I need to use SSLProxyEngine and have attempted to 
implement.  My configuration is as follows:

httpd.conf (from none other than apache2)
---

ServerName www.mysite.com
DocumentRoot /usr/local/apache2/htdocs
   SSLProxyEngine on
   
 ProxyRequests On
 ProxyPass /jsp-examples http://129.17.66.193:8082/jsp-examples
 ProxyPass /*.jsp http://129.17.66.193:8082
   

server.xml (from none other than Tomcat)
---
   
   
   
   
  enableLookups="false" redirectPort="8443" 
protocol="AJP/1.3" />

   
   
  maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
  enableLookups="false" acceptCount="100" 
connectionTimeout="2"
  proxyPort="80" disableUploadTimeout="true" />

.
With this configuration, If I attempt to lauch 
https://myserver.com/jsp-examples, it redirects me to 
http://myserver.com/jsp-examples and I lose my secure connection.  
Based on my error_log file, I see that I need to enable SSLProxyEngine:
[Tue Jan 18 14:40:02 2005] [error] SSL Proxy requested for 
myserver.com:80 but not enabled [Hint: SSLProxyEngine]
[Tue Jan 18 14:40:02 2005] [error] proxy: failed to enable ssl support 
for 129.17.66.193:8082 (k001gxb-0010)

As you can see, I added this directive above in my config files, but 
it's either in the wrong place or there's a missing piece.

I don't want port 80 open at all.  I want everything to run through 
HTTPS.  Can you help me in getting the configuration so that all data 
transfered is through HTTPS?

This is on an Enterprise SUN E450 server running Solaris Sparc 9 btw.

RE: Tomcat 5 java.lang.outOfMemory

[Allistair Crossley]

The registry settings are only available when you use the Windows installer to 
install Tomcat though.

I think you can modify the service.bat if you manually install the Tomcat 
service manually. We change this line :

"%EXECUTABLE%" //US//%SERVICE_NAME% ++JvmOptions 
"-Djava.io.tmpdir=%CATALINA_BASE%\temp" --JvmMs 128 --JvmMx 256

As you can see, the --JvmMs 128 --JvmMx 256 options can be set.

If you're running Tomcat as a Windows service, I don't think the environment 
variables have any effect.  Instead, there are registry settings you can 
adjust.  On my XP system, I have to update JavaOptions under the key:
HKLM\SOFTWARE\Apache Software Foundation\Tomcat Service 
Manager\Tomcat5\Parameters

I would presume the same registry key is used for Win2K.

You might want to consider running Tomcat from the command line until you're 
satisfied with the results, and then switch to running it as a service.  It's 
easier (and safer) to change .bat file settings then the registry.

RE: Tomcat 5 java.lang.outOfMemory

[Allistair Crossley]

Hi,

The latest and greatest of course. Be warned that upgrading to Tomcat 5.5 
series however comes with some additional "work" like Java 5.0, slight variance 
in how to configure data sources, logging and so on, so you may want to go with 
5.0.28 or 30 for now.

RE: Tomcat 5 java.lang.outOfMemory

[Allistair Crossley]

Hi,

The answer is not always to throw more memory at your application.

The best answer is to test whether you actually need more memory or whether you 
are leaking it somehow. 

So find a profiler, get it to talk to Tomcat, and then run your JSP and watch 
the method call tree, heap monitor and hot spots etc... You will need to grab 
something like JProfiler, JProbe or others ... they usually know how to connect 
to Tomcat 5 for you, it's not too hard.

Also, you may want to upgrade your Tomcat I think 5.0.19 had an issue anyway 
with memory, and finally you'll want to ensure when dealing with database 
connectivity that you are freeing up resources like result sets and so on with 
close() calls (depending on what you are doing).

Allistair.

Re: Tomcat 5 / SSL / Digsigtrust Certificate...

[John Urban]

I figured it out.
I was importing the new signed cert to a new alias in my keystore, 
rather than the original key I generated when I created the keystore.

And, Netscape's CA Chain certs work with JBoss/Tomcat5.

• Apache + Mod/Open SSL

there have been a few articles, check onjava.com for example, asynch will 
result in a faster response time, but doesn't guarantee

What is the better way?

Re: Tomcat 5 - Datasource Connection Pooling

[Trond G. Ziarkowski]

Hi!
1)My problem is my working directory is different. I use ant to create 
war file and then i manually stop the server - delete existing war file 
/ existing directory (This is due to some Win TomCat problem .??..). 
Then i deploy it using TomCat Manager. It automatically creates META-INF 
file for me, i do not have META-INF inside my working directory. So 
where i can put my context.xml ?
 

You have already answered this yourself, META-INF/ directory of your war 
file.
The only way to avoid the META-INF directory is to not use a war file, 
as a war file simply is a jar file, and the META-INF is part of the jar 
file specification.

2) What shall i put inside context.xml and what shall i put inside 
server.xml / web/xml ?
 

The example pages: 
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jndi-datasource-examples-howto.html 
tells you exactly what to put in each file. You just have to read them 
one more time and keep focused.
I'll give you some hints as well:
- Leave server.xml the way it was before you started tampering with it.
- Copy CATALINA_HOME/conf///yourapp.xml, to your 
context.xml file, and add your resource specification inside the 
 as in the examples. Then include context.xml in your war file 
in the META-INF dir. Your app must be running for the yourapp.xml file 
to exist as it is deleted when you undeploy your app.
- In web.xml you need to add a  as you can see from the 
examples

Good luck

Re: Tomcat 5 startup crash, please help

[Ben Souther]

There is actually a listing in Bugzilla this.
Would you mind adding your findings to it?
http://issues.apache.org/bugzilla/show_bug.cgi?id=30052
If this is a jsvc bug, your data might help to find it.

That's a pretty old Linux distribution.
I remember having trouble with Sun's jdk on either RH7.0 or RH7.1
There was a fairly buggy release of the gclib libraries in one of them.
Are you able to try your app on a more recent Linux distribution for
comparison?

that's what I did yesterday, but got no response at all. Then I figured 
I might have given too much information on the problem.

So, here's the information on the problem:
configuration: tomcat 5.0.28
   redhat linux 7.1
   vm: 1.4.2_03
I'm trying to install tomcat 5.0. Everything works fine as far as using 
the startup and shutdown scripts provided.

However, when I try to start the server as a linux daemon with jsvc, the 
server crashes.

The catalina.out-log says:


Another exception has been detected while we were handling last error.
Dumping information about last error:
ERROR REPORT FILE = (N/A)
PC= 0x400b0646
SIGNAL= 11
FUNCTION NAME = (N/A)
OFFSET= 0x
LIBRARY NAME  = (N/A)
Please check ERROR REPORT FILE for further information, if there is any.
Good bye.
pure virtual method called
jsvc.exec error: Service exit with a return value of 255

But then again, if I remove the ajp connector entry in server.xml, jsvc 
and the tomcat just work fine.

If I try to start the server again after it has crashed once, the 
catalina.out-log says:

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x400B0646
Function=(null)+0x400B0646
Library=/lib/i686/libc.so.6

NOTE: We are unable to locate the function name symbol for the error
  just occurred. Please refer to release documentation for possible
  reason and solutions.

Does anyone have a clue?
To me, this looks like a problem with jsvc and ajp.
I do have another instance of tomcat running on this system, but I've 
changed the port numbers.

Any hint or help is very much appreciated.

A stack trace or some other error report would help.  It's a bit vague when

If there is, it probably won't be very portable.
Here's a quote from the serlet specs:

Form based login and URL based session tracking can be problematic to
implement. Form based login should be used only when sessions are being

RE : Tomcat 5 and Realm problem

[VAN DER MARLIERE FREDERIC]

Not far. I do use IE and htpts. And I turned off cookies but in server.xml
file. I meet to many problems when I use session cookies and none with
encoded URL. 
Any idea of the way to use realm authentication (FORM method) with cookies
turned off?

Hi Frederic,

you are using IE and https? I got the same error and can't find a proper
solution for it. I bet you have turned of cookies in IE. Turn them on (allow
session-cookies) and it will work again. 

Greetings

Betreff: Tomcat 5 and Realm problem

Hi,

I'm developping a web app in wich I want the users to authenticate via
Realm. I first used BASIC authentication méthod and everything worked fine.
But when I want to use the FORM one, I get the following message when login
and password are correct (if not, I get the error page I configured in
web.xml):

The time allowed for the login process has been exceeded. If you wish to
continue you must either click back twice and re-click the link you
requested or close and re-open your browser

My web.xml looks like:





  protection index
  /
  GET



  myRole




FORM

  /login.jsp
  /error.jsp




myRole


And login.jsp looks like:

  
  
  

  
  
  

  



Does someone have any idea about the origin of my problem ?

Thanks.
Fred.

I had a similar problem like this a while ago, using a PostgresQL DB server on 
a Linux machine, it turned out that I had all three versions of the JDBC 
Driver in my common/lib and server/lib directory.

Once I removed the other two versions, this problem went away.

> Does someone have any idea about the origin of my problem ?

My suggestion would be to check your versions of the JDBC Driver you are using 
and make sure it is the correct version and working correctly.

No. You'll need to look at this in detail, and I recommend doing some
of the testing with really simple stuff (such as static files).

Yes, this sounds like the one host has a misconfigured resolver.  Check
/etc/hosts and /etc/nsswitch.conf (if that machine runs a Unix-like OS).

Re: Tomcat 5 + hostname

Andoni,

I didn't set anything in virtual hosts in server.xml. The only thing there
is the default one, localhost.

 I just want to use server's hostname, not a domain name of the server.
such as  http://servername:8080/  accessed by other computer which is
connected in our company's network.  I don't think  i need to set up virtual
host in xml in my case.  Also I found i don't get response from the server
if i ping the server's hostname from other machine which is connected in our
company's network.  But i can ping the server by using the server's IP
address.  I think I might to resolve ping the se host name first.

Post your server.xml (or at least the relevant parts) with no HTML comments

Failing that, read the documentation, it shows how to set up virtual hosts

Hi,

While upgrading application servers from Tomcat 4.0.5 to Tomcat 5.0.29 I
am noticing slower browser response when hitting the tomcat
5 servers.  

We use tomcat as an application server for a data collection
application.  In one of our larger installs where there are 10
application servers, I have started upgrading to Tomcat 5 from Tomcat
4.0.5.  All 10 application servers have identical
configuration (less disk space differences), 2x1.4GHz (SMP), Win2k, 2GB
RAM.  All 10 are running j2sdk 1.4.2_02.  Just off the cuff,
I'd say it's 15% slower than tomcat 4.0.5.  Watching CPU performance,
the hardware is not being taxed on either the old version or
the new one, but the time for the browser to update is slower.  I'm
fairly certain that the network is not a contributing factor as
all servers are on the same 1 GB backbone and I'm testing to the same
endpoint over the internet.  The tomcat 5 install has no
special configuration, no session replication (I removed the balancer,
ROOT and server web applications from the filesystem).

Anyone else seen this?  
Any ideas where to look?

Hi,
For Tomcat 5.0, JDK 1.3 is supported, including on Windows 2000.  The
behavior you're seeing is normal: the startup window launches tomcat and
then goes away.  If you'd like it to stick around, run "catalina.bat

TC4.1 and TC5.0 have almost the same directory structure, except in TC5.0,
${your.app}.xml is under ${catalina_home}/conf/${engine}/${host}. Oin order
to deploy your web app, put your war or expanded war into
${catalina_home}/webapps/${host}. If you use struts, drop off struts.jar to
WEB-INF/lib. If you use database stuff, drop off jdbc jar to common/lib.

WebappClassLoader: Failed to open JAR
java.util.zip.ZipException: Too many open files
