RE: Tomcat 5.5.x crashes almost every single day.
Hi, You must look at your java code in order to find any function that are deprecated. Sometimes this functions are the problem of memory leaks, high cpu usage, etc...

Probably important: === - 2x Xeon, 3 GB mem - Linux 2.4.26 - Java 1.5.0_06-b05 - Apache Tomcat 5.5.15 - CATALINA_OPTS=\ -server \ -Djava.awt.headless=true \ -Dfile.encoding=UTF-8 \ -XX:MaxPermSize=256m \ -Xms1024m -Xmx1024m - Connector port=8009 protocol=AJP/1.3 maxThreads=200 minSpareThreads=25 maxSpareThreads=50 backlog=20 connectionTimeout=1 enableLookups=true redirectPort=8443 / - mod_jk 1.2.15 - Apache Httpd 1.3.34 - 8 Tomcat vhosts - 8 webapps - each webapp runs on separate vhost - each webapp is Apache Cocoon 2.1.7 - system load avarage: usually under 0.5 - http load: not more then 20-30 concurrent req The pain: crashing Tomcat == Everything works right until Tomcat suddenly crashes, what happens almost every single day. Sometimes it crashes with OOME / out of heap (heh, is 1GB not enought!?), but somtimes NOTHING wrong is logged into the logs - it just stops responding to requests (hangs). When Tomcat stops responding to requests JK eats all of 256 Apache HTTPd MaxClients so other httpd vhosts stop responding also. Disaster! Any ideas before abandoning Java technology? ;) Default Tomcat logging facility seems to be useless to me. j.u.l. logging.properties semantics looks like a programmers joke made to users (!). And even with swallowOutput it logs everything into catalina.out (?) I found none decent log4j-tomcat-virtual-hosts-logging-manual in Tomcat docs also. Is Tomcat a production ready reference j2se server or just a finish it yourself proof of concept toy? I've been crond-restarting Tomcat 4.1 on Java 1.4 every night for more than a year, and now I have to restart Tomcat 5.5.15 on Java 1.5 AND apache httpd also almost every single day. From my -user point of view, Tomcat doesn't change in a good direction. In fact in it is probably changing in wrong direction - at least the 4.1.x logger element has been working 'out of the box'. Come on! Am I the only one that has such problems with Tomcat? -- T. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Read-Only Context with Tomcat + Hibernate
Hi all, Im making a Web application with Apache + Tomcat + Mod_Jk + Hibernate + Postgresql. I need that hibernate binds factory to JNDI but when I do that it gives me and error that context is read-only. Is there any method to implement this or any config tag that makes context writable?.

RE: Read-Only Context with Tomcat + Hibernate
Yeah Kenevel, I know this (This is what I am doing) but I want to give a name to Hibernate's SessionFactory like session-factory name=java:comp/Hibernate/blahblahblah and in that case is where Tomcat says me that Context is read-only. I want this because I'm doing a Tomcat Cluster with some servers and each one must have a SessionFactory with same name in order to use Tomcat Persistent sessions manager on a postgresql database. Do you know anything about naming SessionFactory object in Tomcat? Thanks a lot, Abraham Fernández Álvarez Dpto. de Informática FNAC ESPAÑA S.A.

I need that hibernate binds factory to JNDI but when I do that it gives me and error that context is read-only. From memory Tomcat has a JNDI context that is read-only, but which can accept values bound to it in the configuration files. So you can set up a data-source in the conf/Catalina/localhost/yourcontext.xml file and bind this to a JNDI name. This is then available to be read (only). There will be docs on this but it looks something like this: Context path=/yourpath docbase=/var/www/webapp/ ... Resource name=jdbc/datasourceJndiName auth=Container ... / /Context Incidentally, Spring is a superb way of integrating a Java webapp and Hibernate Mike - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
