RE: All threads (150) are currently busy....

[rlipi]

Hi,
it means that all threads are currently performing some request.

It can have two reasons:

1) High load of the server - requests come quicker than they are
finished. You can increase "maxThreads" or you can look into your app
why it takes so long time.

2) Some requests are not finished due to some bug in your app. On Linux
you can send "kill -QUIT" to your Tomcat process. You will receive stack
traces of all VM threads and you can see where the threads currently
are.

All threads (150) are currently busy....

[Pavle]

After several days of good woking my Tomcat 5.0.16 on RedHat 9.0 box stops accepting 
connection on SSL connector. In catalina.out I am recieving this message: 

SEVERE: All threads (150) are currently busy 

My server.xml file for SSL connector is the following: 

 
   
 

I tried to put smaller connectionTimeout but it does not work too. 

I am not able to find anything on Google. 

Thanks

Re: apache -tomcat problem

[Bill Barker]

The session bug can cause two different requests to start using the same
session.  Most people that reported the bug simply saw information leaks
between the two requests.  Of course, what happens to the app depends on
what it is doing with the session information.

RE: Tomcat 4.1.30 Hung!!! With High Traffic

[Innovest Ken]

I only use tomcat, without using Apache... Because my
site are mainly jsp.

Yes, I have a script to kill the tomcat server before
starting again. And yes, I saw the 'All threads(150)
are busy' error message.

Re: Tomcat 4.1.30 Hung!!! With High Traffic

[Innovest Ken]

hi,

Sorry for reposting, cause i keep getting message not
delivered...

For your questions, top shows cpu around 40%, actually
we have trace our cpu usage for the week, it peak at
50% and average 30%. For memory, it peak at 60%,
average 25%. 

No, the database is in another server thru a firewall.
Initally, we suspect the connection not closed
properly, but after we enable the 'removeAbandoned'
and 'logAbandoned' and check all connections are
closed, tomcat still hangs.

Debug level set to '0'.

Tomcat 4.1.30 Hung!!! With High Traffic

[Innovest Ken]

hello all,

Currently, I have Tomcat 4.1.30 running on Linux
Redhat 9, using jdk 1.4.2_03. It is now running live
and every day it will hang at least once. We are
unable to see any error message in the log file. The
site is having a hit of 20 request per second with
most of the requests need the database connection.

I did a thread dump before the tomcat hangs, but it is
too big to be displayed here.

I can post any more info upon request. Any help???
Thanks

Here is part of the server.xml:

Tomcat virtualhost bug?

[Trond Hersløv]

Hi, I need some help here.
 
Running: Apache 2.0.49, Tomcat 5.0.24 and jk2 2.0.4. Tomcat and the
webserver running on separate machines.
 
The webserver is set up with to virtualhosts. 
test1.athome.no
test2.athome.no
workers2.properties is set up so all *.jsp request are sent to Tomcat.
 
[channel.socket:172.20.201.92:8009]
 
[uri:/*]
 
On Tomcat I have to webapps: app1 and app2.
app1 should be for test1.athome.no
app2 for test2.athome.no
 
I thought everything was fine, BUT then I realized that I could access app2
like this: http://test1.athome.no/test2  .
What am I doing wrong?
 

.
.


 
The virtual host for test2 is set up in the same way. How can I prevent a
virtual host from having access to all the other webapplications?
 
I appreciate any help I can get.

RE: session data in Tomcat 5

[Shane Linley]

I am a ZoneAlarm Pro user and when I first ran Tomcat on my desktop (with
ZapPro) it sabotaged the cookies that TC was using, and from memory TC
started to encode the session id in the URL. I would recommend looking at
the privacy settings in zonelabs to see what it is doing with user
identifiable information and particularly cookies.

I havn't used Integrity before but it does have the forever troublesome
"Privacy and Productivity Features" found in ZapPro. Start with downgrading
the level of security for cookies (or set up your local PC to be trusted
when it comes to cookies" and things might just get better for you.

Regards,
Shane.

Thanks Ben.  I kept telling myself that it should work just fine,
particularly since Tomcat has been one of those things that for me "just
works" with little or no tinkering (I like that kinda thing).

The Zone Labs thing is installed on the desktop, when I open it's config
window it's called "Zone Labs Integrity Desktop".  When I click on the
help/about link it sends me here

Error using taglibs - unable to find setter

[Ravi Mutyala]

Hi,
I created a tag which extends from the html:text tag.
I'm using tomcat 4.1.30.
when I use this tag, I get the following error. 
-
org.apache.jasper.JasperException:
/win_002_PMT_Manage_Cstmr_Prtfl.jsp(70,26) Unable to find setter
method for attribute: dType
	at

The line in the jsp uses the tag that i created. the tag has the
setter method for  dType.
The same taglib is working in the application that is presently
deployed in weblogic. We are trying to migrate the same to
tomcat  and I am getting the above error.
Any clues?
Thanks in advance

Re: Tomcat 4.1.30 Hung!!! With High Traffic

[Parsons Technical Services]

What does top show?
Is the cpu loaded?
Is the memory maxed?
Is the database on the same machine?

When you say hang it can have many meanings. When it "hangs" does the
process die, or does it simply stop responding? Is it a true stop responding
or just a very long delay?

With that level of traffic it may be that you are simply over running the
machine and it can't respond.

What is the debug level set to?

Please only post once. It could cause some list members not to respond.
Reposting the next day isn't to bad but every few minutes will tick people
off.

Tomcat Hung!!! Help needed

[Innovest Ken]

hello all,

Currently, I have Tomcat 4.1.30 running on Linux
Redhat 9, using jdk 1.4.2_03. It is now running live
and every day it will hang at least once. We are
unable to see any error message in the log file. The
site is having a hit of 20 request per second with
most of the requests need the database connection.

I did a thread dump before the tomcat hangs, but it is
too big to be displayed here.

I can post any more info upon request. Any help???
Thanks

Here is part of the server.xml:

RE: Tomcat 4.1.30 Hung!!! With High Traffic

[Denise Mangano]

I am not sure if I have an answer but hopefully this will help. I posted
a similar problem back in April - I have the same exact environment.
The one thing that I have noticed is from the same code in my server.xml
my maxProcessors="75".  I have noticed that when Tomcat does hang I try
to shut down Tomcat but the process does not die so I actually have to
kill it.  At that point I've checked my logs and see:

Apr 4, 2004 2:19:43 PM org.apache.tomcat.util.threads.ThreadPool logFull
SEVERE: All threads (75) are currently busy, waiting. Increase
maxThreads (75) or check the servlet status

After posting to the list it was suggested to increase the number of
servers for the connector to match what Apache allows.  Unfortunately I
got so wrapped up in my code that I never made this change.  Just today
I have increased the number of maxProcessors in Tomcat to 150 which is
equal to the number of MaxClients in Apache - I am hoping this change
helps.

Ken - when you shutdown Tomcat do you run into the same problem of
having to actually kill the process?  Also afterwards do you see a
similar message in your catalina.out?  Are the number of MaxClients in
Apache the same as the number of maxProcessors you have in your
server.xml?

So then the next question that comes to mind if this setting does the
trick how many processors/clients are too many?  For example what if
changing Tomcat to match Apache settings causes the application to still
max out but at the new number of maxProcessors.  I would imagine the
next step would be to increase both but what number is too high?

best and simple way of login mechanism

[Arora, Avinash]

Hi,
   I want to provide a login page for my web applicatioin. I used the
memory realm, by making changes in the server.xml. But it started giving
me Connection errors, and I was not able to see the web pages. Then I
commented the Memory realms tag and then I was able to see the web pages
correctly. I tried to use the JDBC realms, but it also gave me same
problems. 
Can some body please look at the sample server.xml that I use for JDBC
realm? I am using the realms for ROOT context only.
What is the best way to provide the login page on tomcat.

tomcat hanging during SSL handshake

[Rudy Wade]

We're running tomcat 5.0.16 with Java 1.4.1.
I'm seeing this problem after things have been running fine for a while and 
the load
starts increasing.

What happens is the HTTP Coyote connector does not gracefully recover
from an OutOfMemory exception and it gets into a situation where it hangs in 
the
middle of the SSL-handshake.

Is there a known bug that causes this to happen?
We're thinking about upgrading to 5.0.24, but it'd be nice to know that this
will solve this problem rather than just hope so.

not getting debugging info out

[Asya]

Tomcat 5.0.16 on RedHat 9

I've changed the debug level on the HTTP Coyote connector in the 
server.xml config file to 9, but I'm not seeing any additional 
debugging messages generated by the connector in the tomcat log 
files.  I've turned up the debugging settings on all of the components 
via the server.xml file and via the admin application, and the only 
additional debugging messages I get are some unpacking messages from 
the WAR manager.

Any suggestions, ideas?

RE: Bug in Tomcat 5 realm example (j_security_check, again)

[Summers, Bert W.]

>From other comments on the list I added this to the top of my login.jsp

if (session.isNew())
{
  String referer = request.getHeader("Referer");
  if (referer == null)
  {
response.sendRedirect("index.jsp");
  }
  else
  {
response.sendRedirect(referer);
  }
  return;
}

Then I had a problem that people would login, view some stuff and the go to
another web site.
Of course they book marked the login page (I know they should not, but they
do).
After visiting other web pages they hit the bookmark back to the login page.
This caused the first if to fail, so I added this part.  (I put a user
object in the session)

// now check remote user and session user
User u = (User)session.getAttribute("USER");
String remoteUser = request.getRemoteUser();
if(remoteUser != null && u != null)
{
  if(remoteUser.equals(u.getUsername()))
  {
response.sendRedirect("index.jsp");
return;
  }
  else
  {
// seems the user does not match
session.invalidate();
response.sendRedirect("index.jsp");
return;
  }
}

For my site my failed page is also login.jsp.  I created my own custom login
which does some checks and uses attributes in the request to give feedback
to the users (bad password, expired account, etc).

Subject: Bug in Tomcat 5 realm example (j_security_check, again)


This really concerns using j_security_check.  (I know there have been many
posts on this subject but I haven't seen the answer I need and I haven't
found much in the way of documentation on j_security_check).

Tomcat 5 comes with a simple example of  how to use j_security_check for
form based login ( http://localhost:8080/jsp-examples/security/protected/,
as referred to in the "Realm Configuration HOW-TO");

The example fails to redirect correctly after a failed login.

That is, if the user enter a valid username/password combination on the
first try, everything is fine.

If not, the user gets the error page, which has link back to the login page.
If she then enters the correct username/password, she is redirected to the
/login page/.  It appears that the user now is logged in.  I.e. she can now
access protected pages.

In other words, the login page -> error page -> login page redirection is
'losing' the url of the originally requested page.  I suspect that a simple
modification to login.jsp and error.jsp would fix this, but that requires
knowing where j_security_check put the url of the originally requested page.
I haven't founded any documentation on that.

If you know, or have any other ideas on fixing this, please let me know.

Thanks,

bw

How was this module compiled?

If it was compiled against the apache 2.0 source it will not work with

Please don't put URGENT in the title. It may be urgent to you, but it

Session Unbound

[Ravindra Gupta]

 I have 2 problems

1) I am keeping connection into session . My requirement is that i have to release  
this  connection once Session is inactivated/expired .I have given an
implementation where the unbound method of class implementing 
HttpSessionBindingListener  is getting called , but it is called after the session is 
made invalid and since session is already invalidated i can't access Connection Object 
kept into session .

My understanding was that Once a Session is expired , unbound methos is called and 
than only session becomes inactive . This is not happening in Tomcat while in weblogic 
its working correctly ?Any suggestions how to ensure that unbound method gets called 
before Session is invalidated.


2) When i take connection from DataSource , sometimes i am getting following excepting 
when trying to set AutoCommit on DB2 environment

Configuring mod_jk2/jk2 Via The JMX Console

[Wilson Jimmy - jiwils]

The mod_jk2/jk2 web page indicates that a JMX console can be utilized for
runtime configuration changes:

"On tomcat side, you must enable the JMX proxy. This is done by setting
"modjk.webServerHost" and "modjk.webServerPort" in jk2.properties to point
to the web server port that contains /jkstatus. ( recent versions of jk and
mod_jk are required ). You can also add mx4j-tools.jar to server/lib and set
"mx.enable=true" in jk2.properties to enable the console, or use your
favorite JMX console or tools. You could also select http and/or jrmp
protocol, with mx.httpPort, mx.httpHost, mxjrmpPort and mx.jrmpPort."

I have completed the configuration changes mentioned above, but I can not
find the mentioned JMX console.  Is it a web console?  Is it a GUI console?
Is something used from a shell?  If it is a web console, what is the context
for the URL?

Furthermore, what are the interfaces of the JMX bean proxies that are
mentioned?  Are they "standard", "dynamic/model", or "open" mbeans?  Is
there a good page out there that details what the interfaces of the
mentioned MBean proxies look like?

Does anyone configure mod_jk2/jk2 in this manner?  If so, can you show me a
sample client?

Any pointers/help would be greatly appreciated!

Jimmy

Importing chain certificate with keytool causes "keytool error: java.lang.Exception: Input not an X.509 certificate"

[Ben Monnahan]

I'm new to all of this, so I may be making an obvious mistake, but I've
looked all over and can't seem to find a solution.

I'm following the instructions for installing a certificate from a CA
found here:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/ssl-howto.html

Everything went fine until the step where you import the chain cert.
I entered this command:
keytool -import -v -alias root -keystore .keystore -trustcacerts \
-file amon-chain.cer

And got this error:
keytool error: java.lang.Exception: Input not an X.509 certificate

I copied both certs (chain and server) from a web browser into separate
text files and saved them.  They are base64 encoded and the chain is in
pcks7 format.  I made sure to get the -BEGIN CERTIFICATE- and
-END CERTIFICATE-.  If I used keytool -printcert it prints it out
OK, so I'm assuming that it is of the proper format.

java version: Java(TM) 2 Runtime Environment, Standard Edition (build
1.4.2-b28)

tomcat version: 4.1.24-LE-jdk14


Does anyone have any ideas what I'm doing wrong?

(Please CC me as I get the digest version and would prefer to get these
separate.)

Thanks
Ben

Re: Use of SNMP to monitor Tomcat

[disposablehero3000-jakarta]

Hello Hut Carspecken,

Another thing you can try is to monitor Tomcat by
using  a custom plugin with OpenNMS
(http://www.opennms.org); OpenNMS can then talk with
the JMX part of Tomcat in order to poll the health
status (without SNMP).

There is an article at the IBM site about how to do
this:

http://www-106.ibm.com/developerworks/java/library/j-jmx3/

You could also write a small SNMP agent that could
talk also JMX directly with Jakarta. The agent will
talk back SNMP with your NMS (you will have to write a
bridge).

Another thing you could try is to write a Servlet that
also can talk JMX with Tomcat; This servlet could send
SNMP traps to your NMS in case of problems. The NMS
(OpenNMS for example) will then redirect this trap to
a ppropriate group.

I really like this OpenSource SNMP Java stack:

http://snmp.westhawk.co.uk/

Hope this helps.

JV.

ssl, verisign, no common encryption algorithm

[Michael E. Allen]

Greetings!
I am running tomcat 4.1.27 and having trouble importing a global id 
certificate from Verisign.  My server works fine with a self-generated 
certificate, but as soon as I replace my self signed certificate with 
the one from Verisign, I get a message from firefox that it is unable to 
communicate with the server securely because they have no common 
encryption algorithm.  Tomcat 5 exhibits similar behavior.

I have carefully followed the instructions at both:
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/ssl-howto.html
-and-
http://www.verisign.com/support/csr/tomcat/v00.html
Any ideas?

RE: Another source for MD5 encryption

[Shapira, Yoav]

Hi,

>BTW what is the difference between an encryption algorithm and a
digesting
>one?

See http://www.webopedia.com/TERM/M/message_digest.html for a good
definition of the relationship.

Specifically for MD5:

MD5 was developed by Professor Ronald L. Rivest of MIT. What it does, to
quote the executive summary of rfc1321, is:
[The MD5 algorithm] takes as input a message of arbitrary length and
produces as output a 128-bit "fingerprint" or "message digest" of the
input. It is conjectured that it is computationally infeasible to
produce two messages having the same message digest, or to produce any
message having a given prespecified target message digest. The MD5
algorithm is intended for digital signature applications, where a large
file must be "compressed" in a secure manner before being encrypted with
a private (secret) key under a public-key cryptosystem such as RSA.
In essence, MD5 is a way to verify data integrity, and is much more
reliable than checksum and many other commonly used methods.

I have tried to compose a simple test which simulates the real thing,
but I did not succeed to reproduce the error. For simplicity reason of
the test code all my classes, except the servlet class which was in the
webapps, are placed in the {$CATALINA_HOME}/shared/classes. All code in 
the shared/classes has AllPermissions according to the catalina.policy. 

When I was sure that everything works fine with the tests I tried same
approach on the original code (as Filip Hanik already suggested but not
server/classes because ClassNotFound error). I have moved all code
concerning security  (implementations of Policy, Permissions, User
groups, Log. Module, etc.) to the {$CATALINA_HOME}/shared/classes and
gave AllPermissions to this code source through my security system. In
webapps I have left only servlet class that use security. Now it works
perfectly. Maybe problem is in the class loader (/shared/classes is
served with different class loader than /webapps ?!)


Best regards

Viktor

JSP Compiling - painted in a corner?

[Jason Palmatier]

Hello,

I'm trying to precompile JSPs and have run into some
trouble with the mappings.  First off I CANNOT use the
Ant build method as specified in
"http://jakarta.apache.org/tomcat/tomcat-5.0-doc/printer/jasper-howto.html#Web%20Application%20Compilation";
due to a lack of certain UNIX commands on the machine
I'm running on (An iSeries server running a QShell
interpreter in case you're interested).  I get
complaints about the "which" command and I am sure
other commands are missing as well.  So, I am
attempting to compile all the JSPs using jspc
directly.  The archives are full of references to this
but most come down to RTFM, "Use this Ant script" or
"compile to your working directory" all of which I've
either already tried, can't use, and don't want to use
in a released product.
   I've successfully created .class files, copied them
to the classes directory and integrated the generated
xml servlet mapping fragment into my web.xml.  I
received "requested resource not found" when I tried
to access the first compiled page.  I did some more
research, noted that all my classes were part of the
org.apache.jsp package and created an org/apache/jsp
directory under my classes directory and copied all my
classes over to it.  I left the web.xml alone and
restarted tomcat.  I still ran into the "requested
resource not found" error.  I then tried modifying the
web.xml servlet definitions and mappings to see if
fully qualified class names were a problem.  None of
these attempts worked. 
  So, my question is:  If my class files are part of
the org.apache.jsp package and exist in an
org/apache/jsp directory rooted in my applications
WEB-INF/classes directory shouldn't they be found if
my web.xml defines the servlet and servlet mapping as
below:


  
org.apache.jsp.entry_jsp
  
org.apache.jsp.entry_jsp


.
.
.


  
org.apache.jsp.entry_jsp
   /entry.jsp


I have a feeling the subdirectories my jsps exist in
before they are compiled are the problem, as hinted at
in a few archive posts, but am at a loss as to what to
try next.  Is there a way to get jspc to include these
subdirectories in the package name?  Does it even
matter if they are?  Any help or pointers on this
would be greatly appreciated.

Jason

How to setup keystoreFile in server.xml for Tomcat-5.19

[Zsolt Koppany]

Hi,

I would like to define the path of "keystoreFile" in server.xml with a
relative path but the example below throws a FileNotFoundException. It does
work when I use absolute path (that I don't want to).

As far as I understand the documentation, if I use relative path it must be
relative to catalina.base.

What is my mistake?

I use tomcat-5.19 under Windows-XP

keystoreFile="webapps/srv/keystore"
keystorePass="mypass"

Hi,


After being assured by someone on this list that JNI worked on the latest tomcat and JK2 versions I thought I'd give it another shot.

As far as I can tell there is no way its going to apart from possibly on windows.


Can anyone tell me authorititively that it can work at all?

Re: Session Timeout and "Direct Reference to login page"

[Jonathan Eric Miller]

I found out about a few other functions that make it bit easier. I think I
have it working using the following,

public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
if(((HttpServletRequest)request).getRequestedSessionId() != null &&
((HttpServletRequest)request).isRequestedSessionIdValid() == false) {
RequestDispatcher rd =
request.getRequestDispatcher("/WEB-INF/sessionexpired.jsp");
rd.forward(request, response);
}
else {
chain.doFilter(request, response);
}
}

The strange thing is that this page seems to only intermittently be
displayed. i.e. it is catching the case where the session expires, but, in
some cases since I'm using container based security, it is going back to the
login page. Sometimes it goes to this page first, and then brings up the
login page. Other times, it just goes straight to the login page. I need to
look into it further. I have SingleSignOn enabled, so, I'm not sure if that
might have something to do with it. I need to do more testing. In theory, I
think it should go to the login page each time. So, I'm thinking of putting
a check in my login page similar to the above that just shows optional text
stating that the session has expired.

Another thing that I'm wondering is if it is possible to use a servlet as
the login page for Tomcat rather than a .jsp file.

Best Scheduler/Cron for Tomcat?

[Steven J. Owens]

Hi all,

 What's the best scheduler or cron for use with tomcat?  

 I've been googling and Quartz and Jcrontab seem to turn up often.
The Quartz website says it's used by some Jakarta projects, and I see
some references to Quarts in commons-beanutils documents in google.

 What we're doing specifically: scheduling out-going phone calls
from a VoiceXML system to automatically call users at their preferred
time.  I suspect we're going to see calls "cluster" at certain points
(e.g. 6:00, 6:30, 7:00) so the method that starts the call will have
to be multi-threaded, or queued.  If I can get some support for that
from the scheduler, so much the better.

 We're on tomcat 4.x at the moment.  I plan to move up to 5, but I
have a ton of things to do, and I've seen a few posts here that
suggest that moving to 5 might involve non-trivial time and
frustration.  Our app is pretty vanilla, so I'm not especially
worried, but I have twenty-seven priority-1 tasks on my plate, so...

logrotate and cronolog for log rotation

Is there anyone here using cronolog and/or logrotate? I could use them for

Use of SNMP to monitor Tomcat

[Hut Carspecken]

Good Morning Everyone,

I need to incorporate Tomcat as the presentation layer of a larger system and in doing 
so, I want
to monitor it using SNMP.  I understand that Tomcat can incorporate JMX to monitor 
some of its
functions; however, my project calls for the use of SNMP.

Has anyone monitored Tomcat with SNMP or have any knowlege how to do so?

Debug-Logger

Hello,

I installed a log4j.properties - file and the performace suffers extreme
and I get much too much DEBUG entries.

The log4j.properties - file looks like:

log4j.rootLogger=ERROR, A1
log4j.appender.A1=org.apache.log4j.ConsoleAppender
log4j.appender.A1.layout=org.apache.log4j.PatternLayout

# Print the date in ISO 8601 format
log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c - %m%n

log4j.logger.org.apache=DEBUG

In what word can I change DEBUG to get only the normal statements?

Note:

If I set log4j.logger.org.apache=DEBUG into commentary I get a message:

RE: apache -tomcat problem

[Dirk Slootmaekers]

hello,
 
an update on our findings. We had the same problem now with tomcat
3.3.1a after 4 hours of working.
So it is not related to the apache AJP connector but it is in tomcat.
 
any idea what the problem could be? (after a short term after logging in
the user is kicked out).
 
I included the jvm logfile of the tomcat.
could this be caused by the bug you mentioned in 3.3.1?
or is this a coding bug?
 
thanks

I think that this is the first time I've ever heard that the
3.3.1a
stand-alone connector worked better than the AJP13 connector
;-).

There is a session race-condition bug in 3.3.1a (BZ #15894) that
is fixed in
3.3.2.  It is possible that this is the real problem you are
seeing, and it
is only showing up with the AJP13 connector because you are
hitting Tomcat
harder in that configuration.  However, I'm just guessing here
:).

Otherwise, you'll need to provide more information for anyone to
have a shot
at figuring out the problem.  This would include things like:
1) are the broken requests reaching Apache? (from the Apache
access logs)
2) are the broken requests reaching Tomcat? (enable the acces
log on Tomcat,
mod_jk logs).
3) is the session cookie reaching Tomcat (set 'debug="1"' on the
SessionID
element in server.xml).

Can I change Tomcat's default character encoding?

[Allistair Crossley]

We are having a host of problems with character encoding at the moment. Somehow 
between the UI and the Struts Action our euro symbols are being turned into question 
marks. I have fiddled with the JVM file.encoding, using JSP page directives for 
content type and much else besides. I thought Java strings were UTF-8 by default.

Anyway, I stripped off the JSP page directive for encoding and it appears the tomcat 
default becomes Latin 1 ISO-8859-1. The euro character does not appear in this charset 
and I need Cp1252 to be default. 

Can I change Tomcat's default charset?

Thanks ADC

RE: CGIServlet -- tomcat

Mark, thanks for the reply.  Yes, it's still the only issue.  I'm trying
to cut everything down to make it very simple.  All i'm trying to get work
is the perl file 14all.cgi (google it).

It works through apache 1.3.x/2.x etc.  and I'm almost 100% i had it
working using tomcat 4.x a while ago.  however, since upgrading everything
across the board to 5.0.x i can't recall when it actually broke.  could be
my memory is failing.

the perl portion i believe it doesn't like is when it sets the header and
the expiration time.  if i remove that line, everything is printed to the
screen in html...but no png info.  in the logs i see it being generated
and spat out.

RE: problem with JSP -> no data returned

Just a few curious questions.

Are you running this as a service, from the console or from the shortcut?

Are you logged in as an administrator? Where you when you installed?

What are the permission setting on the directories that you installed to?

Just thinking of a far fetched idea. If the permissions are read-only on the
files you installed then you would not get any warnings in the logs or jsp
being compiled. Although it should kick back an error on the web page,
stranger things have happened.

RE: session data in Tomcat 5

[Shane Linley]

I am a ZoneAlarm Pro user and when I first ran Tomcat on my desktop (with
ZapPro) it sabotaged the cookies that TC was using, and from memory TC
started to encode the session id in the URL. I would recommend looking at
the privacy settings in zonelabs to see what it is doing with user
identifiable information and particularly cookies.

I havn't used Integrity before but it does have the forever troublesome
"Privacy and Productivity Features" found in ZapPro. Start with downgrading
the level of security for cookies (or set up your local PC to be trusted
when it comes to cookies" and things might just get better for you.

Shane.

Thanks Ben.  I kept telling myself that it should work just fine,
particularly since Tomcat has been one of those things that for me "just
works" with little or no tinkering (I like that kinda thing).

The Zone Labs thing is installed on the desktop, when I open it's config

I have tried to compose a simple test which simulates the real thing,
but I did not succeed to reproduce the error. For simplicity reason of
the test code all my classes, except the servlet class which was in the
webapps, are placed in the {$CATALINA_HOME}/shared/classes. All code in 
the shared/classes has AllPermissions according to the catalina.policy. 

When I was sure that everything works fine with the tests I tried same
approach on the original code (as Filip Hanik already suggested but not
server/classes because ClassNotFound error). I have moved all code
concerning security  (implementations of Policy, Permissions, User
groups, Log. Module, etc.) to the {$CATALINA_HOME}/shared/classes and
gave AllPermissions to this code source through my security system. In
webapps I have left only servlet class that use security. Now it works
perfectly. Maybe problem is in the class loader (/shared/classes is
served with different class loader than /webapps ?!)

concerning security  (implementations of Policy, Permissions, User
groups, Log. Module, etc.) to the {$CATALINA_HOME}/shared/classes and
gave AllPermissions to this code source through my security system. In
webapps I have left only servlet class that use security. Now it works
perfectly. Maybe problem is in the class loader (/shared/classes is
served with different class loader than /webapps ?!)


Best regards

Viktor

Believe me, you've nothing to feel stupid about.  We've all been there.
One thing to bear in mind, and I've had to tell myself this at least a dozen 
times over the last year, is that there are thousands of people developing 
commercial applications with Tomcat right now.   If something fundamental, 
like session handling, were ever to stop working, there would be hundreds of 
posts to this list, all of them complaining about the same thing.  Within a 
day, there would be a fix for it.  Over the next few days, you would see 
hundreds more complaining about the same bug accompanied by hundreds of posts 
from the likes of Yoav Shapira, Tim Funk, Philip Hanik, (and several others) 
answering the same question over and over again, telling people exactly what 
version to download to fix it.  If you don't see that scenerio on this list, 
keep looking at your own setup.

I'm glad it's working for you.

PS: Did the put the Zone Labs product on the server, or just on your desktop?
Thanks Ben.  I kept telling myself that it should work just fine, 
particularly since Tomcat has been one of those things that for me "just 
works" with little or no tinkering (I like that kinda thing).

The Zone Labs thing is installed on the desktop, when I open it's config 
window it's called "Zone Labs Integrity Desktop".  When I click on the 
help/about link it sends me here
