Re: ACCESSING TOMCAT JMX SUPPORT REMORTELY VIA THE RMI CONNECTOR
Hi, --- Ursprüngliche Nachricht --- Von: jiang ying [EMAIL PROTECTED] An: tomcat-user@jakarta.apache.org Betreff: ACCESSING TOMCAT JMX SUPPORT REMORTELY VIA THE RMI CONNECTOR Datum: Wed, 21 Sep 2005 16:26:00 +0800 hi, I know the way to access Tomcat JMX support via http adaptor. I also know how to monitor an application via JMX by registering an mbeanserver. But I really confused about accessing Tomcat JMX support via RMI connector: 1. how to configure Mx4j RMI connector with Tomcat 5.5, since only Activating JMX MX4J Http Adaptor could be found in the Tomcat website. 2. after configuring RMI connector, how can I access Tomcat JMX support programmatically? I am not clear about the mbeanserver that tomcat mbeans has been registed. How can I make use of the connector, thread pool, servlet information that Tomcat has already monitored and controlled. Thank you. :) Have a look at http://jakarta.apache.org/tomcat/tomcat-5.5-doc/monitoring.html. You can then use e.g. MC4J (http://mc4j.org/confluence/display/MC4J/Home?) for monitoring Tomcat.

Re: ACCESSING TOMCAT JMX SUPPORT REMORTELY VIA THE RMI CONNECTOR
Hi, Before posting my question, I have studied http://jakarta.apache.org/tomcat/tomcat-5.5-doc/monitoring.html. It explains the way to activate HTTP adaptor. Well it explains how to activate jmx remote monitoring right at the start of the page. Did you follow the link to SUNs web site? There you'll find a thorough explanation what all the possible properties and their meaning are. I mean the properties in those boxes in the 'Enabling remote JMX' section, i.e.: set CATALINA_OPTS=-Dcom.sun.management.jmxremote \ -Dcom.sun.management.jmxremote.port=%my.jmx.port% \ -Dcom.sun.management.jmxremote.ssl=false \ -Dcom.sun.management.jmxremote.authenticate=false Regards Dirk -- Lust, ein paar Euro nebenbei zu verdienen?

Re: jndi question
Hi Sean, --- Ursprüngliche Nachricht --- Von: Sean Rowe [EMAIL PROTECTED] An: tomcat-user@jakarta.apache.org Betreff: jndi question Datum: Mon, 22 Aug 2005 01:26:49 -0500 I have tried for several hours now to get connection pooling for my MySql database to work, but have been unable to do so. I keep getting this error: javax.naming.NoInitialContextException: Cannot instantiate class: org.apache.commons.dbcp.BasicDataSourceFactory It's bombing out on this code: Properties p=new Properties(); p.put(Context.INITIAL_CONTEXT_FACTORY,org.apache.commons.dbcp.BasicDataSourceFactory); p.put(Context.PROVIDER_URL,jdbc:mysql://localhost:3306); Context initCtx = new InitialContext(p); // here's where it dies You're mixing up some concepts here. Context.INITIAL_CONTEXT_FACTORY is meant to provide the name of a factory producing JNDI contexts, not a factory for producing JDBC DataSources. The same goes for the next line of code. Context.PROVIDER_URL is not used for providing information about a database connection. There is extensive documentation on the tomcat web site regarding JNDI ressource configuration. Have a look at the following URL: http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-resources-howto.html Can someone please help me, or at least point me in the direction of some documentation that I've missed?

I recommend putting the context definition in its own content.xml. On redeploying my application tomcat wouldn't find the driver class anymore. Mind you not the class itself but the definition of what class to load. This problem was solved by putting the context into context.xml. regards Dirk -- GMX DSL = Maximale Leistung zum minimalen Preis! 2000 MB nur 2,99, Flatrate ab 4,99 Euro/Monat: http://www.gmx.net/de/go/dsl - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
re: how do others deal with classloader not being recycled
Hi, I am assuming that this FAQ entry is still valid for Tomcat 5.5.9: Why does the memory usage increase when I redeploy a web application? Because the Classloader (and the Class objects it loaded) cannot be recycled. They are stored in the permanent heap generation by the JVM, and when you redepoy a new class loader is created, which loads another copy of all these classes. This can cause OufOfMemoryErrors eventually. This could explain why, when I redeploy my webapp many times, I eventually run out of PermMemory. I am curious what others do, in production, because of this issue? Have a look at the following page: http://wiki.apache.org/jakarta-commons/Logging/UndeployMemoryLeak We are going to be doing some testing to see about optimizing the memory allocation, but I am curious how others handle this.

I try to do hot deployment via a war file, but it doesn't work at all for me. What I do is just to copy the war file across. The problems I got (happens randomly): - application including war file disappears - Randon error messages, like log4j exceptions occur, it's fine after restrating - Tomcat hangs up I just want to know if someone is using hot deployment and interested how you do it. Thank you Bernhard i use the predefined task supplied with tomcat to deploy my application to tomcat. There are no problems using these tasks. regards, Dirk -- Geschenkt: 3 Monate GMX ProMail gratis + 3 Ausgaben stern gratis ++ Jetzt anmelden testen ++ http://www.gmx.net/de/go/promail ++ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Problem for loading files under WEB-INF/classes
Hi, I want to load some files that I've placed in the WEB-INF/classes directory of my project (particularly the file log4j.properties). The problem is that I always have the same errors logged in stdout tomcat's log file : java.io.FileNotFoundException... you can load your properties via InputStream is = getClass().getResourceAsStream( /log4j.properties ); The files are well-placed, and curiously my webapp can read a ressource bundle file that I provide for i18n, which is in this same directory. I believed that Tomcat automatically place files under WEB-INF/classes into the path of the webapp. I'm wrong ? What's the problem exactly ? Thank you for your help. Note: Running Tomcat 5.5.9 under Windows XP or Windows 2000, JVM 1.5 Works for me with Tomcat 5.5.7/Windows XP and Tomcat 5.5.9/Debian Sarge. regards, Dirk -- Weitersagen: GMX DSL-Flatrates mit Tempo-Garantie!

Re: Tomcat 5.5.9: NamingException cannot be resolved or is not a type - JNDI, MySQL
Have a look at the tomcat documentation: DBCP uses the Jakarta-Commons Database Connection Pool. It relies on number of Jakarta-Commons components: * Jakarta-Commons DBCP * Jakarta-Commons Collections * Jakarta-Commons Pool These libraries are located in a single JAR at $CATALINA_HOME/common/lib/naming-factory-dbcp.jar. However, only the classes needed for connection pooling have been included, and the packages have been renamed to avoid interfering with applications. --- Ursprüngliche Nachricht --- Von: Greg Brownell [EMAIL PROTECTED] An: Tomcat Users List tomcat-user@jakarta.apache.org Betreff: Re: Tomcat 5.5.9: NamingException cannot be resolved or is not a type - JNDI, MySQL Datum: Wed, 08 Jun 2005 17:44:55 -0400 Great! Thanks Torsten. Added javax.naming Now new problem: NamingException: javax.naming.NamingException: Could not create resource factory, ClassNotFoundException:org.apache.commons.dbcp.BasicDataSourceFactory This exposed several other pitfalls. Tomcat distribution did not come with the apache commons jars: collections, dbcp, pool. Installed them in common/lib and all is well. Thanks tons.

Re: Scheduled task in tomcat - how?
Hi, --- Ursprüngliche Nachricht --- Von: Michael Mehrle [EMAIL PROTECTED] An: Tomcat Users List tomcat-user@jakarta.apache.org Betreff: Scheduled task in tomcat - how? Datum: Tue, 17 May 2005 19:16:10 -0700 I need to create an automated task in tomcat that gets launched every two hours or so, does its work and then sleeps again. Have a look at quartz (http://www.opensymphony.com/quartz). The task needs to send some request values via a secure (https) POST to a cgi script running on an outside server, then receive the response, parse it and put it into the database. The response doesn't return the values as request parameters, but instead simply returns records in CSV (comma separated values) format, one record per line. So, here's what I'm pondering: a.. What's the best way to create that automated (scheduled) task and run it as a servlet under tomcat (5.5.9)? See above and look for the quartz initializer servlet then code up your org.quartz.Job, describe it in jobs.xml and put in a CronTrigger for it. regards Dirk -- 5 GB Mailbox, 50 FreeSMS http://www.gmx.net/de/go/promail +++ GMX - die erste Adresse für Mail, Message, More +++ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
