How to? debug large session size? drill down and tools / over 400K is too be for replication
users@tomcat.apache.org We have an application that has a pretty large session size ( 400K). This is causing issues for scalability and makes session replication for fail over quite impractical. What can be used to drill down live and generate a runtime report (perhaps a graph too) showing what http session attributes are the memory hog? We are looking to see not just the attribute that is the issue but perhaps the aggregate (or aggregate of aggregate) of the session attributes and their size in memory.

Re: Recovery from OutOfMemoryError?
1. you may have a memory leak in your code... do some profiling 2. check out abandoned sessions that are due to expire perhaps you can lower the session timeout and that will make some memory available earlier. Craig Berry wrote: Our Tomcat-based app suffers from occasional OutOfMemoryErrors. We have found that we need to manually restart Tomcat when these happen; frequently the Tomcat process appears to be working after the error, but is actually crippled in one way or another by the loss of some key thread. We would very much like to trigger an automated Tomcat restart when an OOME occurs. Does anyone have suggestions on the cleanest, safest way to arrange this?

Re: kerberos,JAAS, and container managed security
Take a look at CAS. It has the added value of: - keeps passwords away from your container and its applications - gives SSO ! - integrates well behind apache for a balancer and other mod_* - works with other languages - existing application integration I have used it with success and replaced an expensive commercial proprietary application for SSO with it. http://www.ja-sig.org/products/cas/ email me off line if you need a hand with this. - [EMAIL PROTECTED] joe bob wrote: Hi, I would like to use kerberos in conjunction with container managed security. I have configured a JAASRealm with Sun's kerberos LoginModule and a basic scenario works fine. I.e, if a user accesses a protected URL, he is challenged with a login screen. The user/password he enters is validated against the kerberos system correctly. We now have a requirement to honor kerberos password policies, for example the mandatory-password-change flag. When set, the user gets a valid ticket but all he can do is change his password. I tried doing this via my standard configuration and the kerberos LoginModule throws an exception indicating the user must change his password but the tomcat form authentication logic seems to treat this as an invalid login and just redirects the user to the error page with no way for the application to differentiate this situation. Is it possible to honor kerberos password policies using JAAS and container managed security? I have looked through the source and the answer appears no. JAASRealm seems to catch various exceptions (e.g. AccountExpiredException) but in the end just returns null to FormAuthenticator as the authenticate() signature does not allow any checked exceptions to be thrown and the FormAuthenticator implementation doesn't seem to anticipate any runtime exceptions from this method. I would much prefer to use container managed security for the usual reasons but also to get (clustered) SSO support. Does anyone see something I missed or have any ideas? Can I use the standard SSO valve with application managed security somehow? Seems doubtful. Thanks.

Re: Cannot send mail from servlet
Running in tomcat 6.x?
Any chance there is a jndi and smtp config setup in tomcat that is
messing with this? Post the code for the sendMail method and any custom
code it calls.
review your web.xml and tomcat configurations for smtp related stuff.

Hi. I'll try to explain my problem, that is about sending an email
with JavaMail API from a servlet. Anyway, it seems to be a more
general problem i'm having with servlet. I'm using Tomcat 5.0. I've a
servlet that process a request, writes to a database some info and
then send a email with a summary to the user.
In the method sendMail() i send the email. I test the method in
isolation and it works fine. I can connect to my local smtp server and
send the email...
Here's the code:
do some stuff.and send the email
logInfo(Sending summary email);
sendMail(summary.toString(),clientEmail);
response.setStatus(HttpServletResponse.SC_OK);
logInfo(Email sent);
}catch(Exception e){
logError(Error sending summary mail to address:
+clientEmail,e);
e.printStackTrace();
}
}
No exceptions are throwed...but it seems that the servlet doesn't
wait for the method. When i test the method in isolation, it takes
some seconds before the mail is sent, and in the smtp local server
application i can see that a connection has been established.
If i call the same code (the sendMail method) from the servlet i get
Email Sent log messagge immediately and the servlet exit..like if
the message was sent. But nothing has happened (no connection is
established with the local smtp server) and no exception is thrown..
Anyone can help me?

Re: Help required setting up smtp server
Your configuration will look for the hostname mailhost in the dns domain of the same machine that the server runs on... If this is a unix box with a /etc/hosts of: 127.0.0.1 localhost mailhost it would explain this behavor. Try changing the mailhost in the config file to smtpabcd and see if the error remains the same. If so, the config is not coming from where you think it is :) Propes, Barry L wrote: could it be your provider or network is blocking port 25 connections through apps other than the standard email app used? i.e. your company might block port 25 if not being accessed by LotusMail or Outlook. -Original Message- From: Mike Peremsky [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 04, 2007 11:28 AM To: users@tomcat.apache.org Subject: Help required setting up smtp server I followed the example in the Tomcat JNDI docs on setting up and sending an email (C:\apache-tomcat-5.5.23\webapps\tomcat-docs\jndi-resources-howto.html) but am still receiving a javax.mail.MessagingException: Could not connect to SMTPhost: localhost, port: 25 The strange thing is that I set the mail.smtp.host=mailhost in the resource definition. - Food fight?
