Ahh... I see the root cause now.  It is indeed caused by the JVM's 
security manager:


Caused by: java.security.AccessControlException:
access denied (java.net.SocketPermission localhost
resolve)

Looking at your original post, I see (forgive the recap, but I wanted to 
refresh the relevant parts):


I  was told I had a security problem so  I added a file called 
chapter1.policy to  /etc/policy.d: 
// These permissions apply to the chapter1 web application 
grant codeBase file:${catalina.home}/webapps/chapter1/WEB-INF/ 
classes/- { 
  permission java.security.AllPermission; 

}; 



grant codeBase file:${catalina.home}/webapps/chapter1/WEB-INF/ 
lib/- { 
  permission java.security.AllPermission; 

}; 



// 
// The permission granted to your JDBC driver 
grant codeBase file:${catalina.home}/common/lib/postgresql- 
jdbc3-8.1.jar { 
  permission java.net.SocketPermission localhost:5432, 
connect; 

}; 


I'm not familiar with /etc/policy.d though as the tomcat download 
stores policy info in $TOMCAT_HOME/conf/catalina.policy.  You'll have to 
verify that /etc/policy.d is really the policy file used.  I can offer 
this bit of policy code based on an example in catalina.policy:


grant codeBase 
jar:file:${catalina.home}/common/lib/postgresql-jdbc3-8.1.jar!/- {

 permission java.net.SocketPermission localhost, connect;
}

If you look at the Sun Javadocs for java.net.SocketPermission, you can 
get more detail on what's allowed in the permission line.

How to get Request from RequestFacade

Hello,
I'v been using a valve to perform license checking in my web
application. The method invoke(Request request, Response response) had
access to the Request and Response objects, allowing me to perform
some advanced operations. For instance, I made use of instructions
like:

Session catalinaSession = request.getSessionInternal(false);
catalinaSession.access();

or

Session[] managedSessions = request.getContext().getManager().findSessions();

Now, I'm moving the license validation code to a Filter. How do I
access org.apache.catalina.connector.Request/Response in the method
doFilter()? I see that I can only cast to a RequestFacade object:

public void doFilter(ServletRequest sRequest, ServletResponse
sResponse, FilterChain chain)
 throws IOException, ServletException
   {
  RequestFacade cRequest = (RequestFacade) sRequest;
  ..


but now, I cannot use the Facade to access the Request. How can I
solve this problem? Is it desirable accessing Catalina specific object
from a Filter? Should I rewrite my code/ redesign my license
validation framework? It is a very complex one, hance it may require
some effort. May you redirect me to some useful articles/resources?


Many thanks

May I ask what exactly you want to do with the facade?  Seems like you 
could do what you want with a request or response wrapper instead.

That's the point, I don't know much about request/response wrapping.

I don't need the Facade itself, what I need are the real Catalina
Request/Response objects hidden behind it. I don't know how to get
them from inside a Filter.

Re: How to get Request from RequestFacade

Ok... do you need them to modify the request and/or response?  Or are 
you trying to pull some information from the original tomcat internals?


I first assumed you were attempting to modify the request or response, 
so a wrapper is ideal.  All you have to do is create a class that 
extends HttpServletRequestWrapper or HttpServletResponseWrapper and 
override the methods you want.  Then in the filter, just instantiate 
your request or response class with the original request or response in 
the constructor.  When you chain to the next filter, just pass on the 
new request and response objects.

Usertransaction

2007-09-06 Thread Gerard Biemolt

Hi All,

I'm currently trying to create a transaction between a standalone
application and a web service. By starting a usertransaction in
the standalone app and bridging it to/with the web service.
However I'm unable to get use a transaction in the web service.
I took these steps:

- published a transactional webservice with apache axis on tomcat 5.5
- added to /conf/server.xml
  Transaction name=UserTransaction factory=
com.arjuna.mw.wst.UserTransactionFactory/
- added to /conf/context.xml
   ResourceLink name=UserTransaction global=UserTransaction type=
com.arjuna.mw.wst.UserTransactionFactory/
- added the following lines to the code:
InitialContext ctx = new InitialContext();
ut = (UserTransaction) ctx.lookup(java:comp/UserTransaction);
which gives the javax.naming.NameNotFoundException: Name UserTransaction is
not bound in this Context

Am I missing some xml-statements somewhere?

thanks in advance,

Gerard

by the way, I'd be glad if I was able to read the StandardSession. I
mean, even if it's not possible reading the Request, maybe it's easier
accessing the Session behind the StandardSessionFacade.

Tomcat Farm Deployment and Statistics

Is there a way to distribute the deployment of an application through many
tomcat's farm instances in different machines setting a context path that is
different than the war's name?

Is there a way to centrally collect statistics of usage of all of the

Re: Can two Tomcat web apps deadlock each other?

2007-09-06 Thread Wm.A.Stafford


Alexey,
   Thanks for taking the time to reply.  I'll try all your suggestions 
but I wanted to investigate the windows vs linux possibilities.  Does 
the fact that this Tomcat behavior does not occur on the windows-based 
development server offer any clue as to  what may be happening on the 
linux server when Tomcat hangs?


Thanks again,
-=bill

Alexey Solofnenko wrote:
There can be a simple problem with locking - see 
http://tomcat.apache.org/faq/windows.html#lock . On Linux the files 
are usually not locked, so you can get class not found exception 
when a jar file is replaced with a new one.


Ask administrators to get the stack trace (and check if CPU is at 100% 
or not - maybe it is not a deadlock). Otherwise you can look for a 
problem for a very long time.


You can also add try/catch with finite number of retries  around 
connection code. Please  also check that your application shuts down 
cleanly - no exceptions are thrown during shutdown (but they should be 
logged) and preferably there are no finally() methods.


Wm.A.Stafford wrote:
Thanks Alexey.  Unfortunately, the server in question is not ours and 
we do not even have log in on it, so any kind of sane analysis is 
probably out of the question.
All we can do is try deploying another version with changes that will 
either fix the problem (we hope) or yield some more information about 
what is going on.

We are deploying a newer version of a web app to run in the same 
Tomcat instance (1.4.31) as the existing version.  On our 
development servers, winXP,  if the new version encounters a 
startup problem the production app will start and only the new 
version will fail.


On the production server, which is linux, Tomcat seems to 'hang' on 
the first failure encountered when starting the new app and nothing 
further happens. Tomcat has to be restarted after deleting the new 
app when it enters this state.  In the localhost log the last log 
entry is the exception logged from the new app and there is no 
further logging.  Since we have been doing some database changes 
the usual error that causes this is Jakarta DBCP connection failure 
but we have also seen it for a missing class file.  So I  don't 
think the error per se is at the root of the problem.


To me this looks like a deadlock.  Is it possible for one Tomcat 
web application to deadlock with another? An obvious difference is 
windows vs linux servers.  Could there be some config issue for 
Tomcat on linux that would lead to this behavior?


We are completely stumped by this, any ideas or suggestions would 
be appreciated.

POST data lost when switching URL using mod_rewrite and mod_jk

Hi folks!

I Have the following setup:

Apache/2.2.4 
mod_ssl/2.2.4 
mod_jk/1.2.25
mod_rewrite (?)
Apache Tomcat 5.5.23

Browser == Apache + mod_rewrite == mod_jk == Tomcat


This is a Linux machine, and mod_rewrite is used to switch to SSL on certain 
URLs.

Problem: the POST data is lost whenever a form on a http page sends data to a 
page that gets its URL rewritten to https.
This goes as folllows:

http page = form post to http url = rewrite url to https, switch to SSL = 
display https url

No data arrives when using POST!
I know there is a bug that limits the maximum post size to x KB, but in my 
case, the post data is a just a few text fields.
Any idea as to why this happens?

Regards,


Michael

mod_jk errors and http status code 503 under load

2007-09-06 Thread Damien Corbishley

Hi, 

 I'm getting stuck with an error we are seeing on our production server
under load. 

 I've googled and found many posts on similar topics but I haven't found
an answer yet, 

 I was hoping somebody here could shed some light on my issue:

 

We upgraded our combination of Apache,Tomcat,Java all running on Solaris
10 to 

Apache 2_2.0.55.build2

Tomcat 5.5.23

Java 1.5.0_06-b05

 

Our Apache Tomcat connector is AJP/1.3.

 

It's all installed on the same server, we have no tomcat clusters and no
load balancers.

 

With a few (10) concurrent users accessing the various JSP's everything
worked as expected, all our functional tests passed.

We opened more up live traffic to the server and starting seeing the
following error message:

 

[Thu Sep 06 02:23:00 2007] [error] ajp_service::jk_ajp_common.c (1758):
Error connecting to tomcat. Tomcat is probably not started or is
listening on the wrong port. worker=worker1 failed

 

On the client side this was being reported as a 503 and our
intelligent browser was re-submitting the request and generally, 

on the second time, the request would be successful. 

After an hour we then had a Solaris panic, and after analyzing the crash
using scat I can see that the cause was:

 

panic string:   BAD TRAP: type=9 rp=2a1015332d0 addr=0 mmu_fsr=0

 

and looking further into the trap, it seems to be network related.

 

trapip:tcp_conn_request+0x894 (0x4, 0x2000, 0x136ec00, 0x3a2b9a44040,
0x40e03960300, 0x40dedc247c0)

ip:squeue_drain+0xe4 (0x300015ddec0, 0x40e2021c1c0, 0x411666de,
0x135f2c0, 0x3a2b9a44040, 0x3)

ip:squeue_enter+0x358 (0x300015ddec0, 0x38fca5e0d80, 0x3000426b640,
0x3a2bd674c00, 0x0, 0x1)

ip:tcp_wput - frame recycled

 

I am still trying to work out if the crash is a symptom of the browsers
resubmitting the failed requests and we've hit a Solaris bug that we
haven't got a patch for,

Or if the two errors are unrelated and it was coincidence that we
panicked whilst having mod_jk errors. 

 

 

Any help/pointers in resolving the mod_jk error would be appreciated, I
included the brief crash information as it may be relevant. 

Thanks

 

Damien

 Subject: Re: Problem with form based JSP authentication using Firefox with 
 Tomcat

 Are you saying you tried what I suggested, or that you have already
 tried it? It seems like the problem is a caching issue to me.

 What URL are you trying to access to trigger the login - you're not
 accessing the login.jsp directly are you? (I have to ask...)


 In the second instance the browser is setting JSESSIONID as a cookie,
 instead of as a URL parameter, but that shouldn't make a difference.
 The response.encodeURL method only encodes the URL with JSESSIONID if it
 can't see the same value in a cookie in the request.

 The value of JSESSIONID *may* change with each new session, but it won't
 be created until you hit a JSP. So the first time it's only created
 when you hit login.jsp, where it's encoded in the URL because no
 previous session id was found in the URL or cookie.

 The cookie still exists locally after you logout, until you close the
 browser down, so it's not added to the URL the second time round, but as
 the existing ID is an invalid session it triggers the authentication valve.



 You should compare the server response headers rather than the request
 headers, to see if the server is correctly sending the Cache-Control info.

 I tried this without success. I've attached the livehttpheader output 
 below. What seems to happen in Firefox is the first time I go to the login 
 page, it passes the jsessionid to j_security_check.
 If I then invalidate the session, and go to log in again, it calls 
 j_security_check without this identifier. This might be why I'm not getting 
 redirected to the member page, but I'm not sure of that.
 Like I said, this works fine in IE, but firefox still seems to either be 
 losing its bundle after the session is invalidated or incorrectly caching 
 the login page as the member page I'm trying to access.

 I've just cut and pasted the differences between the headers of the 
 successful login, and the unsuccessful login (ie. no redirect).

What do you mean by 'rewrite url to https, switch to SSL '? Do you send

In other case, if you do not send redirect, why do you switch to SSL on

Re: Quartz

2007-09-06 Thread Andrew Hole

I found something interesting, maybe is what I need!
Spring and Quartz together is a good solution but I don't want another
component in my java web application.
What's your opinion?

1) It would be helpful to show an example of how to configure Quartz to work
without a custom servlet. It can be done and is probably the most likely way
people will use it within a J2EE application. I recently implemented
something like this, and had to figure it out for myself since the Quartz
docs weren't very explicit. Basically, you
-Configure your web app to use the Quartz initializer servlet, loading on
startup. For example (from web.xml):

servlet
servlet-namequartz/servlet-name
display-nameQuartz Initializer Servlet/display-name
servlet-classorg.quartz.ee.servlet.QuartzInitializerServlet
/servlet-class
load-on-startup1/load-on-startup
/servlet

-Add a quartz.properties file to your classpath, indicating how jobs will
be loaded (as well as the quartz system properties). For example (from
quartz.properties):

org.quartz.plugin.jobInitializer.class =
org.quartz.plugins.xml.JobInitializationPlugin
org.quartz.plugin.jobInitializer.fileName = quartz-jobs.xml
org.quartz.plugin.jobInitializer.overWriteExistingJobs = true
org.quartz.plugin.jobInitializer.failOnFileNotFound = true

-Add an xml file configuring your jobs and triggers, using the file name
specified under the org.quartz.plugin.jobInitializer.fileName property.
For example (from quartz-jobs.xml, in this case):

job
job-detail
namealertJob/name
groupalertJobs/group
job-classcom.somecompany.AlertJob/job-class
volatilityfalse/volatility
durabilityfalse/durability
recoverfalse/recover
/job-detail
trigger
cron
namedailyTrigger/name
groupalertTriggers/group
job-namealertJob/job-name
job-groupalertJobs/job-group
!-- every night at 2:15AM, M-F --
cron-expression0 15 2 ? * MON-FRI/cron-expression
/cron
/trigger
/job

Again, I think this is the most flexible, easy to use way to implement
quartz, and I'm surprised it's not documented better. In most systems I use,
I don't want to hard-code something like a scheduled process that might be
subject to frequent scheduling change.

2) The author mentions the userThreads setting for application servers to
allow Quartz to use user threads. Unfortunately, I'm kind of thread-dumb, so
I don't exactly know what this means or why it's important. What happens if
Quartz is deployed without this setting? What implications does this setting
have to other aspects of server performance (will it cause a conflict with
some other setting)? I actually am in the middle of deploying an app that
uses Quartz on OC4J and would like to be aware of the implications and
necessity of this setting.

Hi,

This doesn't sound like a real Apache httpd version. You can check the 
real version with httpd -V or when using log level info in the error 
log of httpd.


Worker or prefork MPM?


Tomcat 5.5.23

If you are in a general update situation, switch to 1.5.0_12 or whatever 
seems to be recent and not only a couple days old.


And finally mod_jk-version?


Our Apache Tomcat connector is AJP/1.3.


What's the configuration of the connector element in server.xml?


It's all installed on the same server, we have no tomcat clusters and
no load balancers.

With a few (10) concurrent users accessing the various JSP's
everything worked as expected, all our functional tests passed.

We opened more up live traffic to the server and starting seeing the 
following error message:


[Thu Sep 06 02:23:00 2007] [error] ajp_service::jk_ajp_common.c
(1758): Error connecting to tomcat. Tomcat is probably not started or
is listening on the wrong port. worker=worker1 failed


Is Tomcat on the same machine, or on another one?

What do you get for netstat -an| grep TOMCATPORT where you replace 
TOMCATPORT with the port number your Tomcat AJP connector listens on?


How many ESTABLISHED, how many of other states (SYN_SENT, CLOSE_WAIT etc.)?

What's you mod_jk configuration?

On the client side this was being reported as a 503 and our 
intelligent browser was re-submitting the request and generally,


on the second time, the request would be successful.

After an hour we then had a Solaris panic, and after analyzing the
crash using scat I can see that the cause was:


Solaris panic looks very bad. I would definitely open a bug with sun. 
I'm not saying that the original problem is there, but it is very 
unusual, that the whole system panics.



panic string:   BAD TRAP: type=9 rp=2a1015332d0 addr=0 mmu_fsr=0

and looking further into the trap, it seems to be network related.

trapip:tcp_conn_request+0x894 (0x4, 0x2000, 0x136ec00,
0x3a2b9a44040, 0x40e03960300, 0x40dedc247c0)

0x3a2bd674c00, 0x0, 0x1)


ip:tcp_wput - frame recycled



I am still trying to work out if the crash is a symptom of the
browsers resubmitting the failed requests and we've hit a Solaris bug
that we haven't got a patch for,

Or if the two errors are unrelated and it was coincidence that we 
panicked whilst having mod_jk errors.



Any help/pointers in resolving the mod_jk error would be appreciated,
I included the brief crash information as it may be relevant.

Thanks

RE: Tomcat Farm Deployment and Statistics

 From: bajistaman [mailto:[EMAIL PROTECTED] 
 Subject: Tomcat Farm Deployment and Statistics

 Is there a way to distribute the deployment of an application 
 through many tomcat's farm instances in different machines
 setting a context path that is different than the war's name?

If you want a path different from the name of the .war file, then the
webapp must be located outside of any Host element's appBase
directory.  The webapp is then deployed by creating a
conf/Catalina/[host]/[appPath].xml file containing a Context element
with an appropriate docBase attribute.  (This will override any
META-INF/context.xml file that's inside the webapp.)  You'll have to do
this on each Tomcat instance, of course, but the whole process can be
scripted as needed.

 Is there a way to centrally collect statistics of usage of all of the
 tomcat's farm instances?

You got me - I'm a city boy.  Filip?

Re: mod_jk - connectionTimeout en connection_pool_timeout


Hi Henk,

Henk Fictorie wrote:

Hi,

We are using mod_jk 1.2.21 on Solaris 8. together Apache 2.0.59 with the
worker MPM.
We are moving our applicationserver to a new version which is also using a
new Tomcat version. We now have a split application which is using both
Tomcat 5.0 and the other part is using Tomcat 5.5. For tomcat 5.5 we set the
connectionTimeout to 10 minutes, for 5.0 it is set to 0 (infinite)

For Tomcat 5.0 we see lots more ESTABLISHED connections than for Tomcat 5.5.
While I expected it to be the same.


Hmmm. Maybe I'm missing the point, but I would not share your 
expectation: if you disable the idle connection timeout for TC 5.0, we 
will keep the idle connections around for a long time. OK, you've got an 
idle timeout on the JK side, but it will shrink the pool only until half 
of its maximum size. E.g. if you allow 25 threads per process with 
httpd, the pool will never shrink smaller than 13 connections (unless it 
didn't yet grow to this size) per process.


Of course, since you didn't give us numbers, I'm not sure if this 
suffices to explain your observation.



For the Tomcat 5.0 connections we do not see any errors (except for client
errors).
For the Tomcat 5.5 connections we see errors occuring, claiming that it
cannot connect to Tomcat:

[Thu Sep 06 09:17:15 2007] [2735:0061] [info]

most of those are only info messages. They are telling us, that jk tried 
to use a connection, that has already been closed by Tomcat. Only the 
last line is an error. Usually a closed connection is not a problem, we 
simply search for another one in the connection cache. If we can't find 
an open connection, we use retry number 2 to open a new one. Since you 
set retries to 1, this will not happen.



On the mod_jk side of things we use the same settings for both applications:

worker.maintain=60

# worker template
worker.template.type=ajp13
worker.template.port=
worker.template.lbfactor=50
worker.template.connection_pool_timeout=600
worker.template.socket_timeout=62
worker.template.connect_timeout=3
worker.template.prepost_timeout=3
worker.template.recovery_options=0
worker.template.reply_timeout=60
worker.template.retries=1


On the tomcat 5.0 side the connectionTimeout is set to 0 (infinite)

Connector className=org.apache.coyote.tomcat5.CoyoteConnector
   port=  minProcessors=5 maxProcessors=500
   acceptCount=10 debug=0 enableLookups=true
redirectPort=8443
connectionTimeout=0 useURIValidationHack=false
   
protocolHandlerClassName=org.apache.jk.server.JkCoyoteHandler /



On the tomcat 5.5 site the connectionTimeout is set to 10 minutes:

Connector port= address=a.b.c.d enableLookups=false
emptySessionPath=true
minSpareThreads=20 maxThreads=750 acceptCount=10
connectionTimeout=60
redirectPort=8443 debug=0 protocol=AJP/1.3 /

So, on the timeout settings for Tomcat 5.5 I am using the recommended values
described in the 'timeouts howto' section.
The info messages suggest that I should increase the connectionTimeout on
the Tomcat side. Probably to some value  (connection_pool_timeout +
worker.maintain)??
Or should I set the connection_pool_minsize to match the minSpareThreads??
Or upgrade to mod_jk 1.2.25??

Advice is welcome.

If you are in a general update situation, switch to 1.5.0_12 or whatever

seems to be recent and not only a couple days old.

And finally mod_jk-version?

 Our Apache Tomcat connector is AJP/1.3.

What's the configuration of the connector element in server.xml?

 It's all installed on the same server, we have no tomcat clusters and
 no load balancers.
 
 With a few (10) concurrent users accessing the various JSP's
 everything worked as expected, all our functional tests passed.
 
 We opened more up live traffic to the server and starting seeing the 
 following error message:
 
 [Thu Sep 06 02:23:00 2007] [error] ajp_service::jk_ajp_common.c
 (1758): Error connecting to tomcat. Tomcat is probably not started or
 is listening on the wrong port. worker=worker1 failed

Is Tomcat on the same machine, or on another one?

What do you get for netstat -an| grep TOMCATPORT where you replace 
TOMCATPORT with the port number your Tomcat AJP connector listens on?

How many ESTABLISHED, how many of other states (SYN_SENT, CLOSE_WAIT
etc.)?

What's you mod_jk configuration?

 On the client side this was being reported as a 503 and our 
 intelligent browser was re-submitting the request and generally,
 
 on the second time, the request would be successful.
 
 After an hour we then had a Solaris panic, and after analyzing the
 crash using scat I can see that the cause was:

Solaris panic looks very bad. I would definitely open a bug with sun. 
I'm not saying that the original problem is there, but it is very 
unusual, that the whole system panics.

 panic string:   BAD TRAP: type=9 rp=2a1015332d0 addr=0 mmu_fsr=0
 
 and looking further into the trap, it seems to be network related.
 
 trapip:tcp_conn_request+0x894 (0x4, 0x2000, 0x136ec00,
 0x3a2b9a44040, 0x40e03960300, 0x40dedc247c0)

 ip:tcp_wput - frame recycled
 
 
 
 I am still trying to work out if the crash is a symptom of the

RE: POST data lost when switching URL using mod_rewrite and mod_jk

Ok, that makes it clear to me.
Thanks for the exhaustive reply!

Btw., I didn't configure the servers, I'm just trying to get my forms data 
through and understand as much as possible. :-)

So I switched to GET, but again, I ran into issues, this time it is 
character-encoding related.
The Tomcats all have URIEncoding=UTF-8 set, and it works whithout the 
rewrite-induced redirect.

But when redirect is used, the following happens:

The parameter führung becomes f%C3%BChrung in my JSPs. I did 
AddDefaultEncoding UTF-8 in my Apache config, that doesn't help. Is there a 
configuration option for mod_rewrite or mod_jk that I have to set to make it 
work? I tried the ForwardURIxxx options on my mod_jk, but they didn't help. 
Any Ideas?

Thanks a lot for the help so far!

Michael

 10.3.2 301 Moved Permanently
 
 The requested resource has been assigned a new permanent URI and any

 Clients with link editing capabilities ought to automatically re-link

 The new permanent URI SHOULD be given by the Location field in the

 the response

 new URI(s).
 
 If the 301 status code is received in response to a request 
 other than 
 GET or HEAD, the user agent MUST NOT automatically redirect 
 the request 
 unless it can be confirmed by the user, since this might change the 
 conditions under which the request was issued.
 
Note: When automatically redirecting a POST request after
receiving a 301 status code, some existing HTTP/1.0 user agents
will erroneously change it into a GET request.
 
 So if you are using HTTp Redirect, check your Apache access log. It's 
 likely you will notice, that the browser switched from a POST 
 to a GET 
 during the redirect and the POST Body isn't send by the 
 Browser. Nothing 
 we could do in this case on the server side.
 
 You should try to identify a GET which sits before the POST in your 
 clickstream and do the redirect already there (like e.g. when the 
 browser tries to retrieve the empty form before it tries to send the 
 contents).

Integration with Apache

2007-09-06 Thread Edd Dawson

Hi

New to the list here :)

I have a server setup as follows:

Apache - mod_jk2 - tomcat

There are a number of webapps served by tomcat:

/ROOT - available on http://www.mydomainname.com/

/webapp2 -available on http://www.mydomainname.com/webapp2

/webapp3 - available on http://www.mydomainame.com/webapp3


Now this all works fine, but now I need to add a php forum site onto the
server on the same domain name and have it served on
http://www.mydomainname.com/forum

Trouble is that I cannot for the life of me figure out how to configure this
without moving my /ROOT webapp off the URL http://www.mydomainname.com/ and
into a subdirectory.


Can anyone confirm whether what I want to do is at all possible, and if so
give any pointers as to where i need to be looking to configure it?

Thanks
Ed

Thanks for your response.
You mentioned our setting of retries=1, so I reread the documentation to

It will let you know if it helped.

 simply search for another one in the connection cache. If we can't find 
 an open connection, we use retry number 2 to open a new one. Since you 
 set retries to 1, this will not happen.

Re: How to get Request from RequestFacade

2007/9/6, David Smith [EMAIL PROTECTED]:
 help.  I'm still unclear as to why you need access those object.  If you
 could say more about that, someone might be able to offer a better way
 to do what you want.

ok,

I need to access some of the Catalina Session specific features. In
the Valve invoke() method I perform a call like the following:

// update last access for this session
Session catalinaSession = request.getSessionInternal(false);
catalinaSession.access();

This is very easy to do with an HttpSession as well, but there are
other things that come easy with Catalina objects and I'm not able to
realise using J2EE specific interfaces, i.e.:

// get all sessions active for this manager
Session[] managedSessions = request.getContext().getManager().findSessions();

// find a session by ID
Session session = request.getContext().getManager().findSession(id);

// access the security realm
Realm realm = request.getContext().getRealm();

Hence, I'd like to know if I can perform the above operations in a
J2ee Filter doFilter() method.

Thanks

Re: Tomcat memory issues

2007-09-06 Thread Dwayne

If you don't want to cache internally then you need a distributed caching
scheme.
There is an open source solution from the guys at Terracotta.org they call
Network Attached Memory.  Basically you can deploy a virtual heap against
disk and make your memory as big as you want.  They built all sorts of drop
in config modules already:

synchronous stop of tomcat

2007-09-06 Thread Derek Alexander


Using: 
$CATALINA_HOME/bin/catalina.sh stop
$CATALINA_HOME/bin/catalina.sh start
in quick succession to restart Tomcat,
it is possible that the start operation will run before all ports have been
released by the instance I'm stopping.

Is there a synchronous method for stopping Tomcat, i.e. one that won't
return until the ports have been released at least?

Cheers,
Derek

Re: POST data lost when switching URL using mod_rewrite and mod_jk

I know that's not the answer you like: but why aren't you switching to 
https before it gets complicated, i.e. when a simple request is coming 
in, like for the form page itself?


To debug the problem you described, we would have to find out, at which 
stage the problem starts:


- is the Location header apache httpd sends back for the redirect still 
OK? You can check with a commandline client like e.g. curl.


- if so, is the second request as decoded by apache OK? The access log 
might give an idea about that


- if so, is the forwarded request from mod_jk to Tomcat OK (JkLogLevel 
debug shows a line ...service... which containes the forwarded URL at 
the end)

You should have a connectionTimeout.


Tomcat is installed on the same machine as Apache.

With respect to the number of connections to the tomcat port I can't
give a complete answer - looking at the crash I can see there are around
4000 stuck at TIME_WAIT. Another 30 or so are at ESTABLISHED.


All of those 4000 TIME_WAIT for port 8009? That would be very much, 
indicating, that you are rapidly opening and closing the connections 
between Apache/mod_jk and tomcat. Those connections are supposed to be 
reused for some time.

So set connectionTimeout in the AJP connector (server.xml) to 60

Yes, I agree with you about contacting SUN, I'm digging out our service

I don't see a good reason, why you should get those error messages for 
this configuration. But you should update to a more recent mod_jk in

Hi,

My application uses MemoryRealm and FORM-based authentication. 

In the file tomcat-users.xml, there is an user called view, which belongs
to role users.  The role users is not included in web.xml of the
application. 

If I try to login the application with the user view, I get an error:
HTTP Status 403 - Access to the requested resource has been denied. I
cannot go back to the login page. I have to close the brower or restart the
server to see the login page. 

Clean the browser's cache is not working. It seems the authentication
information is cached in the Tomcat server. Any idea?

will look into it.  What makes me think that load is probably not the 
cause is that  when there are no startup errors everything starts and 
runs as normal in the normal amount of time.  The problem occurs when 
one app fails during startup. For  unknown reasons Tomcat either does 
not get notified of the failure and is left some sort of waiting state 
or Tomcat gets hung trying to shutdown the failed app.


   Thanks again for replying,
   -=beeky

Does 
the fact that this Tomcat behavior does not occur on the

I'm going to take a guess: server load.  How heavily do you stress-test
your webapp on the development server?  What with?  How many concurrent
requests?

Accessing the connection pool

2007-09-06 Thread Scott Marshall


Greetings

I have web applications running connection pools under the name 
jdbc/connectionPool, and these web applications can connect without any 
problems. Now Im working on a security application, to be run as a client 
jar to the webapps. This jar does the lookup onto the multiple 
authentication data sources we have. Can the ConnectionFactory within the 
jar file access the Connection Pools set up by one of the  web applications 
?  If not, any ideas how I can get a Connection Pool on the server that the 
jar file can access ?


The jar file sits in the Tomcat 5.5\shared directory.

At the moment, when I try it I get a naming exception : 
javax.naming.NameNotFoundException: Name jdbc is not bound in this Context


Code in the connection factory :


try

   {

   Context ctx = new InitialContext();



   DataSource ds =

   (DataSource)ctx.lookup(

   java:comp/env/jdbc/connectionPool);



   if (ds != null)

   {

   conn = ds.getConnection();



   if(conn != null)

   {

   LogManager.getInstance().logDebug(this.getClass(), 
Connection retrieved from jdbc/connectionPool.);


   }

   }

   }

   catch (SQLException ex)

   {

   throw new DAORuntimeException(DBConnectionFactory 
getConnection(), ex);


   }

   catch (NamingException ex)

   {

   throw new DAORuntimeException(DBConnectionFactory 
getConnection(), ex);


   }



Code in the Context file :



Context crossContext=true debug=5 path=/ipsl_app 
docBase=C:\dev\ipsl_app\build\web reloadable=true


   Resource

 name=jdbc/connectionPool

   auth=Container

Thanks very much

Thanks Charles, I was reading about JMX and Tomcat and I wonder if is it
better (more secure?) to do it at the low level as you suggested or by using
the JMX API?

Re: Quartz

2007-09-06 Thread Sergey Livanov

Do as you know and as it is more convenient. I can't start with
servlet-class org.quartz.ee.servlet. QuartzInitializerServlet
/servlet-class
init but when has tried spring - all has worked for 5 minutes. It is very
pleased.
In Quartz forum answer badly, it is lazy.
In spring - it is very good. Support is much better.

This my opinion ...

2007/9/6, Andrew Hole [EMAIL PROTECTED]:

I found something interesting, maybe is what I need!
Spring and Quartz together is a good solution but I don't want another
component in my java web application.
What's your opinion?

1) It would be helpful to show an example of how to configure Quartz to
work
without a custom servlet. It can be done and is probably the most likely
way
people will use it within a J2EE application. I recently implemented
something like this, and had to figure it out for myself since the Quartz
docs weren't very explicit. Basically, you
-Configure your web app to use the Quartz initializer servlet, loading on
startup. For example (from web.xml):

-Add a quartz.properties file to your classpath, indicating how jobs
will
be loaded (as well as the quartz system properties). For example (from
quartz.properties):

-Add an xml file configuring your jobs and triggers, using the file name
specified under the org.quartz.plugin.jobInitializer.fileName property.
For example (from quartz-jobs.xml, in this case):

Again, I think this is the most flexible, easy to use way to implement
quartz, and I'm surprised it's not documented better. In most systems I
use,
I don't want to hard-code something like a scheduled process that might be
subject to frequent scheduling change.

2) The author mentions the userThreads setting for application servers
to
allow Quartz to use user threads. Unfortunately, I'm kind of thread-dumb,
so
I don't exactly know what this means or why it's important. What happens
if
Quartz is deployed without this setting? What implications does this
setting
have to other aspects of server performance (will it cause a conflict with
some other setting)? I actually am in the middle of deploying an app that
uses Quartz on OC4J and would like to be aware of the implications and
necessity of this setting.

I think using JMX would make it more complicated and may well decrease
security since there would be yet another port open into Tomcat; others
may have differing opinions.

However, your reference to JMX did remind me of Lambda Probe
(www.lambdaprobe.org), which is a very useful Tomcat monitoring tool.
I've never tried it in a Tomcat clustering environment, but it does
appear to have some support for that.

RE: POST data lost when switching URL using mod_rewrite and mod_jk


 why aren't you 
 switching to https before it gets complicated, i.e. when a simple request 
 is coming in, like for the form page itself?

Unfortunately, that is not an option.


 - is the Location header apache httpd sends back for the 
 redirect still 
 OK? You can check with a commandline client like e.g. curl.
 

No, here's where the trouble starts. It seems like mod_rewrite can't handle 
UTF-8 URLs. I used the LiveHTTPHeaders plugin for Firefox, and here's the 
output:

Original (correct request):
GET /lucene/target.jsp?test=%C3%BCberraschung HTTP/1.1

Flawed redirect:
Location: http://localhost:778/lucene/target.jsp?test=%25C3%25BCberraschung

As you can see, the % have been encoded again.

What can I do about it?


Regards,

Michael



 - if so, is the second request as decoded by apache OK? The 
 access log 
 might give an idea about that
 
 - if so, is the forwarded request from mod_jk to Tomcat OK 
 (JkLogLevel

 the end)

RE: POST data lost when switching URL using mod_rewrite and mod_jk

2007-09-06 Thread fredk2


The mod_rewrites encoding can be changed with option 
'noescape|NE' (no URI escaping of output) 

This flag keeps mod_rewrite from applying the usual URI escaping rules to
the result of a rewrite. Ordinarily, special characters (such as '%', '$',
';', and so on) will be escaped into their hexcode equivalents ('%25',
'%24', and '%3B', respectively); this flag prevents this from being done.
This allows percent symbols to appear in the output, as in 

RewriteRule /foo/(.*) /bar?arg=P1\%3d$1 [R,NE]

This is great, it seems to work for me!

I just found this page, which describes the issue: 
http://issues.apache.org/bugzilla/show_bug.cgi?id=34602

In post #16, it is suggested that RewriteMap esc int:escape is required to 
correctly escape the non-query part of the URL.
Is that true?

Re: an easier way to deploy war file?





Peter Stavrinides a écrit :


If you set up Tomcat correctly, and place all your jars in the correct 
places you can hot deploy the war without a restart. This works over 
plain http, you don't even need access to the server, all you need is a 
password for the manager (it's better to use a database realm).


There are many ways to secure the manager in production, the simplest is 
to remove the manager.xml and host-manager.xml files from the 
$CATALINA_BASE/conf/Catalina/localhost/ directory, or if your 
configuration permits allow the manager url to resolve only on the 
internal network, this is a typical scenario if tomcat is left to run on 
a secure port.




If you do that and want to use the manager again, you should replace 
those files ?

If so, I'll be really annoying to do that.


For my part, I did a deployment shell to do all the gregor's action 
(because my servers are on DMZ).


Last thing, the less applications are deployed the faster the server is.
That is also why I don't use the manager.





cheers

Re: context-param vs env-entry. Ready? Fight!


Hello,


IMO, you should use JNDI variable (env) instead of (context variable).
In that case, there will be no link the application server and you'll 
can deploy your application on another server.


Of course, you ll have to define the JNDI variable in a different way. 
But most important, you'll don't have to change your java classes 
because the JNDI tree will stay the same.

Forgive my ignorance here, but do you mean, say, in a bean?  That

Hello,


If you have a shell, you can use the expect package to catch the prompt.
It may be a solution.

Problem with Tomcat 6.0.xx and JAAS and userContextClassLoader

2007-09-06 Thread A Sunley


Hello all,

We're using Tomcat 6.0.14 and we need to use JAAS for our webapp. We have a
custom login module and it's desirable for us to have the custom LoginModule
.jar inside the WEB-INF\lib directory of our webapp.

However with Tomcat 6 it appears we can only place the jar in the lib folder
of Tomcat, otherwise we get a 'SEVERE: Class com.devtest.auth.UserPrincipal
not found! Class not added' on startup. I can't find much information on
this issue, but the issue is perhaps better described here:
http://support.liferay.com/browse/LEP-2995;jsessionid=C72F970D8B99F4BD60185FB0A1567A8F?page=history

According to the link it is because Tomcat 6 performs a Class.forName()
lookup. 

Is there anyway around this?

Thanks,
Alan.

Question about Session MGMT

2007-09-06 Thread ryoung5367


I was searching the archives, but could not find what I thought I needed??

The problem I have is that when I go to my webapp (IE/Firefox) and login as
say an admin and then open another tab and login as just a user.  The
original admin login will fail if I try to do any administrative functions.

I am sure that I am messing up something with the Cookie used to maintain
session state, but I am not sure how to avoid this when using the same
browser?

Any help would be appreciated.  Thanks in advance

unable to change tomcat 5.5.20 session manager to PersistentManager

2007-09-06 Thread Joe Lopilato

Hi All:
 
I am using tomcat version 5.5.20 and am having problems configuring a
persistent session manager.
 
I added the following to the context element in the context.xml file
located in the tomcat_home/conf directory:
 
Manager className=org.apache.catalina.session.PersistentManager
maxInactiveInterval=60 processExpiresFrequency=1 
Store className=org.apache.catalina.session.FileStore /
/Manager

In order to test whether the above manager configuration changes were
successful, I made the following calls from within my servlet:

  System.out.println( session expir duration:  +
session.getMaxInactiveInterval() );
  System.out.println( session : + session.getClass());

and got the following results which indicate the above manager
configuration was ignored:
session expir duration: 1800
session :class org.apache.catalina.session.StandardSessionFacade

Based on output to the IDE console window, it is clear that context.xml
is being properly parsed. I also noticed that I am able to successfully
set the session-timeout from the web.xml file.

Can anyone tell me whether I have stumbled upon a bug or if I am missing
a configuration step?

Thanks in advance,
Joe

You can't just stick the listener element anywhere you want in

Consult the DTD for the proper place to put listener elements.

Yes Chuck. I did note that as I have consulted the apache docs and
numerous other sources prior to resorting this list.
However, the issue is broader than PersistentManager and appears related
to all manager configurations made via the context.xml file.

For instance, if I configure the standard manager through context.xml, I
again note the configuration (specifically, the session timeout) is
ignored:

 Manager className=org.apache.catalina.session.StandardManager
maxInactiveInterval=65 /

I get the following result from within my servlet:

System.out.println( session expir duration:  +
session.getMaxInactiveInterval() );
System.out.println( session : + session.getClass());

session expir duration: 1800
session :class org.apache.catalina.session.StandardSessionFacade

That's because the Request object isn't an HttpServletRequest object,
which is what you have in your servlet. Without trouble, you can't get
access to this internal object from your servlet.

 do you have a better idea about programmic login, and how to write it?

Check out securityfilter... it keeps the user's principal in the session
instead of somewhere else, so it's easy to get. Not sure if it plays
well with SSO, though.

 Another possibility might be the use of

How are you distributing the traffic among the Tomcat instances? Cant'

If not, you'll have to either copy log files to a central location, or
rig your loggers to report logging information to a single place.

One idea is to use log4j as your logging mechanism (I'm guessing that
the AccessLogValve or whatever it's called uses the standard logging so
you can set it up to use log4j) and use the syslog appender with a host
other than localhost. Have all your TC instances use syslog to report
logging to one, single system's syslog facility. Then, configure syslog
on that target machine to segregate Tomcat/web log messages to a
particular file.

Yes.

 Is there a synchronous method for stopping Tomcat, i.e. one that won't

Not that I know of. Lots of folks have posted to the list somewhat
recently asking basically the same question: how do you know when Tomcat
has really stopped?

The best hack I've heard of is to watch the catalina.out log file for
the magic Tomcat Stopped message. Another option would be to actually
poll the port to see if it's available. They're both pretty ugly options.

 That is because you have one session per browser session.

Or, more precisely, your application is using a cookie to maintain

hostname, path, and name, the second cookie overwrites the first and you
are left with a single login in two different windows/tabs.

 This is why you can log in to an email webapp, navigate away, and if you
 return within the timeout for the email session, you are treated as
 though you never left.
 
 YMMV, because this may not be true of _all_ webapps :-)

Right. One way to allow multiple logins in separate tabs is to disable
the use of cookies on the server (or even your web browser). If you've
been writing your web pages properly, all of your links should have the
session id encoded in them when cookies are not being used, and sessions
will be maintained by using that information instead of cookies.

In this case, you can login as many times as you want in separate
windows/tabs/processes/etc. and you'll get a separate session in each of
them.

 In the file tomcat-users.xml, there is an user called view, which belongs
 to role users.  The role users is not included in web.xml of the
 application. 
 
 If I try to login the application with the user view, I get an error:
 HTTP Status 403 - Access to the requested resource has been denied. I
 cannot go back to the login page. I have to close the brower or restart the

You don't need to kill the browser /or/ the server. You just need to
kill the user's session.

 Clean the browser's cache is not working. It seems the authentication
 information is cached in the Tomcat server. Any idea?

Tomcat links the authentication information for a user to the session.
Once the session is dead, you can re-login. Override the 403 error page
to include your own text including a link that takes you to the
(unprotected) logout page.

RE: Different sessions between JSP and Servlets...

2007-09-06 Thread Mike Cronin

Thanks Christopher.

At this point, the context is coded within the server.xml. I understand that
the context should be placed within a context.xml file within a META-INF,
but doing so has been giving me problems thus far (something I plan to
tackle here shortly).

As for the JSP/Servlet session issues discussed within this thread, I
believe that I have them resolved.

Thanks once again for your valued input.

Best regards,

You should remove both of these attributes from your Context in

Garbage Collection and Class unloading

2007-09-06 Thread Brian Munroe

Can someone explain a little bit about classloading really quick?

Let me preface this with: I am maintaining an application which I did
not develop.

Looking at the WEB-INF/lib directory, it has around 76 different jar
files, some actually used in the application, some (well, most) not.
They either pertain to legacy features or are functionality duplicate
(two different versions of Oracle driver libraries, for example)

I am trying to tune Tomcat because it keeps running out PermGen space,
so I am using jconsole to inspect the JVM.  I suppose it isn't really
a profiler, but it is a start.

According to jconsole, after doing many application development cycles
of remove-deployment of *.war to Tomcat (via manager), it looks like
as many as 20k classes are loaded.  I was under the impression that
the garbage collector would unload classes as necessary.

I tried to force a GC via jconsole, it reduced the heap memory like it
should, and it unloaded a few classes pertaining to reflection, but
nothing like what I was hoping for.  I then leave it be for several
hours, and all magic like, the GC unloads about 4k classes.

First question.   Anyone tell me why it doesn't unload classes when I
am trying to force it?  Is classloading/unloading not even the same as
garbage collection?

Second question.  Is having 20k classes loaded normal for a middle
sized application?  I am assuming if I remove all the unnecessary jars
from WEB-iNF/lib I can reduce that number?  Would it benefit anything
to place them in shared/lib?

Third:  If over 75% of the classes in the jars aren't being called
anywhere in the application, even though they get loaded on the
initial application deployment, shouldn't the GC unload them almost
immediately, since there aren't any open resources using these
classes.

Fourth question:  Do my JAVA_OPTS looks decent?

JAVA_OPTS=-Xms512m -Xmx512m -server
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=8114
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-verbose:gc
-XX:+PrintClassHistogram
-XX:+PrintGCDetails
-XX:MaxPermSize=128m

many thanks!

Brian,

In The Beginning, there was only global scope, and it was Good.

Then someone said, nested scopes would be really convenient, so we
don't have to manage stacks ourselves, and the nested scope was
created, and it was Good.

Then someone else said global scope is evil, as it allows programmers
to be lazy and leads to bad design, and the global scope was abolished,
and it was Good.

Then yet another said hey, when I need to pass new data into a highly
nested method, lack of global scope is a real PITA because I have to
change every method signature in my program, and JNDI was created, and
it was Good.

Finally Martin Fowler said dependency injection, and nobody ever had
to worry about programs making any kind of sense ever again. And it was
Good (for hourly contractors!)

Is it late enough to call it Friday? ;)

Re: Garbage Collection and Class unloading

Others with more experience in the garbage collection may chime in, but 
it's my impression that the garbage collection tends to have it's own 
mind.  You can try to force it, but that's no guarantee it will garbage 
collect anything.  I'd think your best bet is to clean out all the dead 
in-house code and then thin out the dependencies until it stops

RE: Garbage Collection and Class unloading

 From: Christopher Schultz [mailto:[EMAIL PROTECTED] 
 Subject: Re: Garbage Collection and Class unloading

 This used to happen because Class objects were never 
 discarded by the JVM.

That's not true, at least not since JVM 1.2 came into use.  Class
objects are discarded once there are no more instances of that type,
there are no references to the Class objects themselves, and class
unloading has not been inhibited by command-line option.

 using static fields to store big object trees and pushing 
 application data into something managed by Tomcat (JNDI, a
 Valve, or something like that).

There have also been related issues with other oft-used non-Tomcat
libraries, such as loggers. Not sure if all of this undesired references
have been cleaned up.

 The ClassLoader keeps all the java.lang.Class objects
 it ever loaded

Actually, the references go the other way - every instance of
java.lang.Class retains a pointer to its ClassLoader, and the
ClassLoader won't be discarded until all of its loaded classes are gone.
(It's possible that Tomcat's WebappClassLoader keeps track of all
classes it loads - I haven't checked - but the standard ClassLoader
implementations that come with the JRE do not.)  Individual instances of
java.lang.Class can be discarded at any time, as long as the constraints
noted above are complied with.

 and those will eventually go into the PermGen space 
 due to their long lives.

All instances of java.lang.Class are allocated within the PermGen from
the get-go; there is no migration into or out of PermGen.  (The tenured
generation does operate as you describe.)

 I'm a little hazy on PermGen, actually, but I think it 
 /never/ gets cleaned up.

Not true, except if one esoteric, non-standard GC algorithm is selected
for the HotSpot JVM.  PermGen is cleaned up whenever a full collection
occurs.

 Second, class loading and GC are mostly unrelated

Not true - they're intimately connected.  Note that it takes two full
GCs to get rid of java.lang.Class instances after they become
unreachable.  The first discovers that they're no longer active and
queues the instances for some cleanup processing.  The instances
themselves are not discarded until the next full GC, after the cleanup
has happened.

 Yes. You might even want to do -verbose:class if you want 
 some light reading.

At least reading it won't keep you awake...

Re: How to get Request from RequestFacade

2007-09-06 Thread Bill Barker


David Smith [EMAIL PROTECTED] wrote in message 
news:[EMAIL PROTECTED]
 Ok... do you need them to modify the request and/or response?  Or are you 
 trying to pull some information from the original tomcat internals?


From his examples below, it looks like he wants access to the TC internals.

For the OP's original problem, for obvious security reasons TC makes it very 
hard to access the internal TC objects behind the various Facades from a 
webapps code (e.g. a Filter).  It should be pretty much impossible if you 
are running in a sandbox with the default TC security settings.  Overall, if 
you really need access to the internal TC objects, IMHO you are better off 
using a Valve, since the potential need to modify it when you upgrade TC 
versions doesn't go away.  If you can do what you need to do with the 
operations and properties exposed via JMX on the Manager, then that is 
probably cleanest.  Otherwise, you would probably need to use introspection.

 I first assumed you were attempting to modify the request or response, so 
 a wrapper is ideal.  All you have to do is create a class that extends 
 HttpServletRequestWrapper or HttpServletResponseWrapper and override the 
 methods you want.  Then in the filter, just instantiate your request or 
 response class with the original request or response in the constructor. 
 When you chain to the next filter, just pass on the new request and 
 response objects.

 Tremal Naik wrote:

That's the point, I don't know much about request/response wrapping.

I don't need the Facade itself, what I need are the real Catalina

them from inside a Filter.

Thanks,

2007/9/6, David Smith [EMAIL PROTECTED]:

May I ask what exactly you want to do with the facade?  Seems like you
could do what you want with a request or response wrapper instead.

Tremal Naik wrote:


Hello,
I'v been using a valve to perform license checking in my web
application. The method invoke(Request request, Response response) had
access to the Request and Response objects, allowing me to perform
some advanced operations. For instance, I made use of instructions
like:

Session catalinaSession = request.getSessionInternal(false);
catalinaSession.access();

or

Session[] managedSessions = 
request.getContext().getManager().findSessions();

Now, I'm moving the license validation code to a Filter. How do I
access org.apache.catalina.connector.Request/Response in the method
doFilter()? I see that I can only cast to a RequestFacade object:

public void doFilter(ServletRequest sRequest, ServletResponse
sResponse, FilterChain chain)
throws IOException, ServletException
  {
 RequestFacade cRequest = (RequestFacade) sRequest;
 ..


but now, I cannot use the Facade to access the Request. How can I
solve this problem? Is it desirable accessing Catalina specific object

from a Filter? Should I rewrite my code/ redesign my license

validation framework? It is a very complex one, hance it may require
some effort. May you redirect me to some useful articles/resources?

RE: unable to change tomcat 5.5.20 session manager to PersistentManager

 From: Joe Lopilato [mailto:[EMAIL PROTECTED] 
 Subject: RE: unable to change tomcat 5.5.20 session manager 
 to PersistentManager 

 For instance, if I configure the standard manager through 
 context.xml, I again note the configuration (specifically,
 the session timeout) is ignored:

  Manager className=org.apache.catalina.session.StandardManager
 maxInactiveInterval=65 /

Based on looking at the Tomcat code, it appears that this particular
Manager attribute has no effect.  The maxInactiveInterval setting is
overridden by the default sessionTimeout value in StandardContext, which
is 30 minutes, and also, if present, by the session-timeout value in
either the global or the app-specific web.xml file.  Looks like you have
to change the timeout value in web.xml, not the nested Manager
element.
