Re: Class Loader Documentation
- Original Message - From: Ole Ersoy [EMAIL PROTECTED] To: users@tomcat.apache.org Sent: Tuesday, June 17, 2008 4:41 AM Subject: Class Loader Documentation Hi, Reading through the classloader documentation for 6.0 I noticed this: ... However, the standard Tomcat 5 startup scripts ... It seems like this should be: the standard Tomcat 6 startup scripts But I figured I'd check before filing a ticket. Also it seems like this section could be simplified: System - This class loader is normally initialized from the contents of the CLASSPATH environment variable. All such classes are visible to both Tomcat internal classes, and to web applications. So this seems to be saying that normally all classes that should be visible to both Tomcat and webapps are placed in the CLASSPATH environment variable. The second sentence seems to reinforce that placing the libraries in the CLASSPATH makes them visible to both Tomcat and the webapps. Then reading a little further the text seems to be saying Forget all that stuff. Tomcat does not do it this way If I'm reading it right, would it be simpler to just replace the above mentioned text with, System - The standard Tomcat 6 startup scripts ($CATALINA_HOME/bin/catalina.sh or %CATALINA_HOME%\bin\catalina.bat) ignore the contents of the CLASSPATH environment variable (Unlike most java daemons and applications), and instead build the system classloader from the following repositories: ... Thoughts? I think its because its just hard to explain, but maybe it could be made clearer. I think *ignores* is the wrong word. Especially if someone actually looks at catalina bat and sees this line. set CLASSPATH=%CLASSPATH%;%CATALINA_HOME%\bin\bootstrap.jar Doesnt look like that script is ignoring CLASSPATH to me ;) When Tomcat starts up, its internal system classes take *priority* over those in the normal system classloader CLASSPATH. This is to prevent Java DLL hell, making sure that external applications do not see the internal tomcat engine, and making sure that tomcat does not use an external class (eg an xml parser), that may be incompatible with tomcat (Its trying to save your butt). --- add your version here --- ;) Actually look back at TC 5.5... it is getting simpler, believe it or not ;) --- HARBOR : http://www.kewlstuff.co.za/index.htm The most powerful application server on earth.

Re: mod_jk load balancing and cluster node health
Nathan E. Pilling wrote: Is it possible to configure mod_jk to check node status by requesting a specific web application path to see if a cluster node is healthy (and should be included or excluded from the cluster)? I have a web application that runs across multiple tomcat instances and any request be processed by any tomcat node. If an instance of the web app on one of the tomcat servers is not configured properly, I want the connector to exclude it from the cluster. I have written a servlet that returns a status of 503 if something is wrong or 200 if everything is okay. There's not the full story build in yet, but you can combine the various pieces to get the same result: Write an external script, that refularly calls your servlet and add ;jsessionid=.MYNODENAME to the end of the URL (but before the query string). The load balancer will then send the request to it's member named MYNODENAME (stickyness). Now you set fail_on_status to 503 for all LB members. Then the load balancer should put the node into ERROR, whenever it sees a 503 coming back for any request. See http://tomcat.apache.org/connectors-doc/reference/workers.html for fail_on_status. Does that sound plausible?

RE: Tomcat Custom Connector
Hi Bill, Thanks again for your reply. Your comments are very helpfull :) I will definitly have other questions in the future but for now I think I can move forward :) Thanks again, Simon J. To: users@tomcat.apache.org From: [EMAIL PROTECTED] Subject: Re: Tomcat Custom Connector Date: Fri, 13 Jun 2008 19:51:35 -0700 The Adapter is set in the initialize method of the Connector (http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/catalina/connector/Connector.html). You can pretty much just trust that Tomcat will give you an Adapter instance before the first request comes through, since that is the contract. Yes, the current implementation only will give you an instance of CoyoteAdapter, but programming your ProtocolHandler around this is dangerous, since the contract only promises an instance of Adapter. The Adapter is the bridge between your ProtocolHandler and the Tomcat Servlet Container. Once you hand off your Request and Response objects to the Adapter, you can trust that Tomcat will handle all of the Servlet-Spec parts by itself, including finding the Servlet to send the request to. At that point, you are only responsible for communicating with the client over the wire via the InputBuffer and OutputBuffer interfaces. For example, the various AJP/1.3 Connectors (http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/coyote/ajp/AjpProcessor.html) convert the message into AJP/1.3 format before sending it over the wire to Apache httpd. Once you have figured out how to initialize the Request and Response objects to look enough like the wire protocol was HTTP, the rest is really pretty easy :). For non-HTTP protocols (e.g. trying to make Tomcat look like an FTP server), this is the hard part. Simon Aquilina [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hi, I have checked the code in Tomcat again, and although it is very confusing I feel I did understand something here and there :) However I have a question - where is the adapter being set? No Adapter is being initialized in the 'JIoEndPoint', 'Http11Protocol' and 'Http11Processor'. I also checked the 'server.xml' file and this is not being set! From the API documentation I found out the 'CoyoteAdapter'; so is this the default being used for Tomcat? Is it the CoyoteAdapter which is responsible to find the servlet for which the request is? or? Thanks for any comments, Simon J. To: users@tomcat.apache.org From: [EMAIL PROTECTED] Subject: Re: Tomcat Custom Connector Date: Tue, 3 Jun 2008 19:17:03 -0700 AFAIK, there isn't a lot of documentation. But there isn't that much too it. You need to implement a ProtocolHandler (http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/coyote/ProtocolHandler.html) This class is responsible for managing the transport (e.g. ServerSocket) and request threads (but the various EndPoint classes in org.apache.tomcat.util.net may simplify this aspect for you). For best results, this class may implement ActionHook as well (http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/coyote/ActionHook.html). When a new request comes in, it is the ProtocolHandler's job to initialize a Request (http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/coyote/Request.html) and a Response (http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/coyote/Response.html) objects for it, making certain that they get valid InputBuffer (http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/coyote/InputBuffer.html) and OutputBuffer (http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/coyote/OutputBuffer.html) instances to comunicate with the client. Then within the thread, you hand the Request and Response off to the service method of the Adapter (http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/coyote/Adapter.html) that Tomcat will give to the ProtocolHandler. And that is pretty much it :). Using the standard server.xml (as opposed to Embedding), you would configure Tomcat to use your Connector with an element like: Connector protocol=com.myfirm.mypackage.MyProtocolHandler ... / Any other attributes in the Connector / tag will be passed JavaBean style to the ProtocolHandler to handle init options. For the simplest example, look at org.apache.coyote.memory.MemoryProtocolHandler (but this one is mostly useful for unit testing).

logging with multiple web applications
Hi Everyone
Does anyone know how to configure Tomcat such that logging writes to
separate log files for each web application? When we deploy several
instances of our web application, for some reason, the logging output
from all web applications is merged into a single debug.log file.
Apparently, Tomcat uses an extended the log4j package (JULI) to support
logging across multiple web applications, but we are unsure on how to
activate it. I have a feeling we may not be using the right
packages/configuration and would appreciate your guidance.
In our example, each web application has its own log4j.properties file
stored in WEB-INF/classes. The log4j.properties file specifies an
appender with the the location of the debug.log file as follows:
log4j.appender.archivadebug.File=${catalina.home}/logs/debug.log
Even if we specify a different file name for each web application, it
only seems to pickup the first one. It combines logging output from all
web applications into a single log file. Any ideas on why this might be
the same?
Throughout my web application code, I use the following:
import org.apache.log4j.Logger;
..
protected static final Logger logger = Logger.getLogger(Config.class);
..
logger.debug(this is a test log output);
The jar log4j-1.2.14.jar is bundled with the web application and is
located in WEB-INF/lib
How does one make it such that each web application will have its own
log file? For example, say I had the web applications webapp1, and
webapp2 - the debug log file for each could be debug-webapp1.log and
debug-webapp2.log, respectively. Do I need to
import catalina's version of log4j? What is the import line?
Many thanks in advance for your guidance
Jamie

Subject: Re: logging with multiple web applications
Now Jamie, just a word of caution : this guy Chuck sounds
like he's nice and wants to help, but don't get your hopes
up, cause the next time he might just tell you to go read
the log4j documentation..
Actually, the OP appears to have done that, unlike some...
The real question is, has the OP read this:
http://tomcat.apache.org/tomcat-6.0-doc/logging.html
(My guess is that actually has been done as well.) Note that most of the log4j
section in the above applies to Tomcat internal logging, not individual webapp
logging, except where noted.
Apparently, Tomcat uses an extended the log4j package (JULI)
to support logging across multiple web applications
No, JULI is not log4j; JULI is a more flexible replacement for the somewhat
restrictive JDK logging mechanism. Internally, Tomcat uses commons-logging,
but webapps are free to use whatever they please.
each web application has its own log4j.properties file
Look for any more global instances of log4j.properties (or log4j.xml) and get
rid of them.
The jar log4j-1.2.14.jar is bundled with the web application
and is located in WEB-INF/lib
Verify that you don't have any instances of a log4j*.jar in Tomcat's lib
directory and that you have no CLASSPATH environment variable set.
Do I need to import catalina's version of log4j?
No, especially since Tomcat doesn't use log4j, unless you modify it to do so.
log4j.appender.archivadebug.File=${catalina.home}/logs/debug.log
I'd suggest changing all config lines that refer to debug.log to something
unique for each webapp.
Have you placed any jars in Tomcat's lib directory that are shared across
webapps? If so, and if they are doing any logging, it will use the log4j
config of the first webapp to get there. Better to deploy such libraries with
each webapp rather than introduce such crosstalk.

Logging for Dummies in Tomcat 5.5/6.0
Hi. Following another couple of threads which were leading to not much, and where it seemed evident that there was a notable difference in competence and understanding between the protagonists, I would like to start a new one, targeted at Tomcat Logging Dummies like me, but where Tomcat gurus are of course gratefully welcome to enlighten us. Here are the basic premises : Assume that one is not a Java nor Tomcat expert, just someone who has to install a piece of software called Tomcat, because that is what his users would like to have, to run nice Java applications. Assume that one has installed Tomcat 5.5 (or 6.0) on some system just by using the standard software package management system for his Operating System, and consequently finds himself with some Tomcat installation, whose settings and layout have been chosen by a real guru (in both Tomcat and in software packaging). Assume that the Tomcat in question works fine, but that it writes logfiles all over the place (or all over time), and that one would like to understand where these logfiles come from, and either slightly change which logfiles are being produced, or add a specific logfile for a specific application, or something simple like that. Assume that one has read the Tomcat logging page at http://tomcat.apache.org/tomcat-6.0-doc/logging.html and it's equivalent for Tomcat 5.5, and that one has even read the commons-logging documentation at http://commons.apache.org/logging/ but that one admits that one is too dumb to really understand what is said there. I believe also that it can be assumed that one does not know the difference between common-logging, juli, log4j or anything like it, and that one does not really care to know more about it than one absolutely needs to know in order to get a logfile. The kind of things one would like to know are : - where to start ? In other words, here I have a Tomcat and it is working and it is writing logfiles, but I do not have a clue which kind of logging mechanism it is using, either directly or indirectly. How do I find out ? - how does it work ? In other words : it would seem that the kind of logging adopted in Tomcat 5.5/6.0 is very powerful and flexible, allowing one to decide at the top which mechanism is being used, and then define either some overall generic logging settings for the whole Tomcat and valid for all components and applications, and/or refine this at just about each hierarchical level of Tomcat, Engine, Connector, Host, application and whatnot, at whatever level of detail one needs between CRASH and CHATTY. Great. Now, this was also pretty much what one could do in Tomcat 4, by using a Logger element at whichever level one deemed necessary. And it was probably not perfect from a purist or developer point of view, but it was fairly simple to configure for the occasional Tomcat admin. So, without going into many technical considerations about why it was changed, is there a simple set of analogies that one could use between an old and a new configuration, to achieve similar aims ? My purpose is *not* to use the logging interface programmatically, since I have no access to any source code of any of the applications. I would just assume they are doing the right thing so that I can re-direct their output to some file I choose, or to the intergalactic void if I so choose (like /dev/null), or just tell them to shut up via some setup parameter. But, if it looks like one of them is misbehaving, I would like to know how to really squeeze the last logbyte out of it so that I can go and rub the user's nose in it, or bug the developer about fixing his code. - how does one set up a really simple logging configuration, but one that will allow in the future some gradual tailoring and refinement without complete redesign ? In other words, currently I have far too many logfiles and I don't know where they are coming from. I'd like to simplify initially, and then slowly and incrementally, as I get a better understanding of how it works, rebuild what I need in terms of details. My basic purpose is to have logfiles that show me, in not too much detail, when Tomcat starts and stops, the important things that happen to it, and in case of an error, enough information to find out where it happened and why in general terms. a) I have a Tomcat with one single host (localhost) and 3 applications : a manager, a host-manager, and a custom application called MyApp. That's the way it came in the box. Each of those at the moment produces a separate logfile, daily, to which one adds another set of daily catalina logs. That's just a bit much. I would like to have, for the whole of Tomcat : - one monthly file that shows the equivalent of an Apache error log - one monthly file that shows the equivalent of an Apache access log and that's pretty much it. So I need first to undo what's there, and then to put in what's needed. How do I do that ?
Tomcat 6.0 Classloaders
Hi, I was wondering whether Tomcat 6.0 still has a classloader for classes that should be globally visible to all webapps only? I read through the classloader documentation and it seems to be saying that $CATALINA_HOME/lib contains classes that are visible to both Tomcat and the webapps. However this resource: http://helpme.morphexchange.com/tomcat6/help/items/chapter_4_2_shared_lib Is saying that shared/lib contains the classes visible to all webapps... Thoughts?

Re: Class Loader Documentation
I think its because its just hard to explain, but maybe it could be made clearer. I think *ignores* is the wrong word. Especially if someone actually looks at catalina bat and sees this line. set CLASSPATH=%CLASSPATH%;%CATALINA_HOME%\bin\bootstrap.jar Doesnt look like that script is ignoring CLASSPATH to me ;) When Tomcat starts up, its internal system classes take *priority* over those in the normal system classloader CLASSPATH. This is to prevent Java DLL hell, making sure that external applications do not see the internal tomcat engine, and making sure that tomcat does not use an external class (eg an xml parser), that may be incompatible with tomcat (Its trying to save your butt). Ah OK - I see what you are saying. I looked at setclasspath.sh and the first thing is does is clear the users CLASSPATH variable. So seems like the Tomcat startup scripts rebuild the CLASSPATH variable such that only JARS that are available to it on the classpath. So if I were to add more jars to the startup script, those would still be visible to Tomcat and all applications. --- add your version here --- ;) (This is what you're saying I think. When I saw *priority* I started thinking How does it priorize?, and for me it's a little clearer if I understand that the CLASSPATH variable is rebuilt from scratch...assuming that's corrects...OK Here Goes Take 2 When Tomcat starts up, the startup script first clears the CLASSPATH variable. It then adds a few libraries that Tomcat needs to boot, such as bootstrap.jar. These libraries contain additional class loaders that Tomcat delegates to when it needs it's system classes (Libraries visible to Tomcat only and typically contained in CATALINA_HOME/lib). Note that if you add additional libraries to the startup script lines that initialize the CLASSPATH for Tomcat, these will be visible to Tomcat and all running web applications as well. /Take 2 Thoughts?

I've compared JRockit 1.4 and 1.5 in the past against SUN and it was faster for synthetic benchmarks. I don't work for BEA, but I do like JRockit.

Help replacing mod_jserv with mod_jk
Hello Tomcat users: I need some help replacing the functionality of mod_jserv with mod_jk. Here is the situation: We have a legacy web-based java application that uses mod_jserv with load balancing. Typically there are one or more Apache servers with two java servers on the back-end. We also have Apache set up to listen on individual ports so that we can monitor each java server separately. Here is an example from one of the Apache config files: VirtualHost 10.100.1.53:81 ---extra config stuff here--- # App server configuration IfModule mod_jserv.c ApJServMount /servlets ajpv12://host.domain.com:8008/root ApjServAction .html /servlets/gnujsp /IfModule What I would like to do is set up an instance of Apache on host.domain.com itself, just for the purpose of monitoring the health of the java process on the local box. I want it to listen on port 81 just like the web server does. The problem is I cannot simply use the same mod_jserv.so module because the app server has Apache 2 installed and the web server is still using Apache 1.3. I have already spent several hours trying to build a new mod_jserv.so for Apache 2.0 with no luck. I am told that mod_jk can be used to replace mod_jserv. I have mod_jk installed and the module loads fine in my Apache configuration. Where I'm stuck is, how do I duplicate the above configuration on the local box using mod_jk? Any help you can give is *most* appreciated. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Jrockit Vs Sun
I talked to the lead developer for JRockit months ago and he told me they take the code from Sun releases and add it to all the releases. What that means is thier 1.4.x is as fast as the 1.5.x but the difference is functionality they do not port 1.5 functionality to 1.4.x. This is important to me because you may be able to do an upgrade for 1.4.x of Jrockit in production for say BEA and get the performance of 1.5.x. I do not believe Sun does that. Especially since I was interested in performance inprovements of 1.6.0_02 at the time and was wondering what release BEA was going to put that into. Sun has a performance paper about the improvements of 1.6.0_02 over earlier releases and I saw that exibited on a system I engineered so I knew it to be true and was wondering when BEA was going to incorporate the 1.6.0_02 code from Sun. -Tony --- Leon Rosenberg [EMAIL PROTECTED] wrote: Hello, i have tested synchronized vs. atomic performance two years ago with both jrockit and sun 1.5, both 32 bit, and jrockit was clearly faster in synchronization and slower in atomics.

Re: Tomcat 6.0 Classloaders
I was wondering whether Tomcat 6.0 still has a classloader
for classes that should be globally visible to all webapps
only?
Not by default. However, you can edit conf/catalina.properties to create any
classloader hierarchy you want.
So I take it:
common.loader = Tomcat's classes/jars visible to both webapps and to itself.
server.loader = only tomcat
shared.loader = only webapps
So if I wanted hibernate-3.0.14.jar to be visible to all webapps I could stick
in in CATALINA_HOME/shared/lib and set shared.loader =
${catalina.home}/shared/lib/hibernate-3.0.14.jar and now it's visible to all
webapps, but not to Tomcat?
Thanks!

Re: Memory usage in Tomcat 6
9 out of 10 are the heap size problem. Changing the -Xmsnm and -Xmxnm in the tomcatw.exe if you are using Windows. On the 32-bit Windows, you can only allocate 1.2 GB max. If you still have problem, check all the static vars to see any objects are growing forever. If you still have problem, there must be some huge objects created from time to time. You need to use tool like figure it out.

Correct. This is how levels prior to 6.0 worked.
So if I wanted hibernate-3.0.14.jar to be visible to all

shared.loader =
${catalina.home}/shared/lib/hibernate-3.0.14.jar and now it's

Also correct, but I don't know why you'd go to that trouble. Adding
classloaders does not improve performance, nor does preventing the Tomcat
kernel from seeing certain jars buy you anything.

All, My apache installed is has only the mod_jk.sl in the libexec/ directory. I want to know what I need to do in order to to configure my current http to https? I know this is a very general question, but to start, I guess I need to include the directives in httpd.conf: 1)IfDefine SSL LoadModule ssl_module libexec/mod_ssl.so /IfDefine 2)IfDefine SSL AddModule mod_ssl.c /IfDefine Is this enough in order to enable the mod_ssl? Already have all certificates configured in the paths.

I've been sitting here trying to come up with some hypothetical reasons that

point! At least I know what's in catalina.properties now :-).
Actually one case I think is somewhat valid from an administration point of view is if you are RedBoss and you want to say to users Place all shared/provided webapp libraries in /var/lib/tomcat and have the corresponding Tomcat package pre-configured for this.

Connection Pooling and Teradata
I'm not sure if this is the right place to post this question but I've seen through the years that there are a lot of knowledgeable people reading and responding. 1st. I'm running Tomcat 6.0.14 under Windows XP with Java 1.5.09. 2nd: My problem is not getting something working its trying to understand what is happening to see if I can get it to work faster. Basically, I have a web application that communicates with Teradata under Tomcat using a DBCP pooled connection. In my context.xml file I have: !-- Sample Database DataSource Configuration for Teradata -- Resource name=jdbc/teradata1 factory=org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory url=jdbc:teradata://adqaxp01/LOG=DEBUG,DATABASE=Mydb driverClassName=com.ncr.teradata.TeraDriver username= password= validationQuery=Select 1 type=javax.sql.DataSource maxIdle=2 maxWait=5000 maxActive=4 / Via JNDI we get the Resource object, get a connection, create a statement, issue the statement, close the statement and then close the connection. Everything works just fine. But looking at a Teradata command log and then turning on LOG=DEBUG on the URL I see 2 things. 1st. Everytime we get a connection I see a Select 1 followed by a BT/Rollback being issued and 2nd: Everytime we close the connection I see an Abort followed by multiple ET/Commit's being issued I've seen similar things with other DB's and am now wondering if I have a problem or is this the way it is designed to work? Using connection pooling is it normal to issue the above commands when a connection is obtained and closed? Is there something I can do to say don't do it? Is it an Application error, Tomcat error or JDBC driver error? Any and all feedback is appreciated. Thanks, John Katilie
