Manually setting up Tomcat5.0 as service on Windows server 2003 : some questions
Hi I'm trying to manually setting up Tomcat5.0 as a service on a Windows Server 2003. I've already set up my JAVA_HOME and CATALINA_HOME variables, as well as updated the PATH with : %JAVA_HOME%;%JAVA_HOME%\jre\bin\client;. My questions are : - should the service launch the startup.bat ? If so, what about the console output ? Would it be better for the service to launch a shortcut (this shortcut would link to startup.bat and redirect the console output) ? - on the server shutdown, would it matter that the shutdown.bat is not launched ? - do I have to do something more that the points above ? Thanks in advance ! Cheers, ZedroS

This worked perfectly with Tomcat 5.5.9, but when upgrading to Tomcat 5.5.10 or above (and we've tested on 5.5.10, 5.5.12 and 5.5.15) the webapp cannot access the external resources we place outside of the Tomcat webapps directory.

RE: Setting up connection pools on the fly...
This sequence is typically correct (with the close portions in a finally{}
block.) You could add some timing around each of these statements, and
determine the exact impact. Think about the relative complexity of each of
these operations
- Get a context - hashed lookup
- Get a datasource - hashed lookup
- Get a connection - DNS resolution, TCP connection, parameter transmission
and negotiation, authentication... (possibly more depending on the driver
and DB)
- Make the statements - query optimization, caching (or cache lookup if a
repeat), execution
- Close resultsets - clean up
- Close statements - clean up
- Close connection - clean up, close TCP connection
Now, replace the two connection operations with hash-type operations - one
to remove it from a pool (list, collection, hash) and one to put it back.
This is where you get the savings. This leaves the statement execution as
the next largest time consumer, but that is an invariant in this problem.
Empirically, I can tell you I added pooling to an older web app recently and
some 'typical' web requests improved by about 2.5X. More importantly,
Oracle 8i stopped running out of resources, saving operations from nightly
DB restarts.

Subject: RE: Setting up connection pools on the fly...
The point of connection pooling is to eliminate the overhead
of setting up and tearing down a (TCP, database, AAA)
connection for every database transaction (typically, the web
request in a web app.) This can add 100s or 1000s of
milliseconds to every request, and is quite expensive.
If you can architect your application so that there is a JNDI
data source for each server (database server, instance, etc.)
with its own pool of connections, you can always call
setCatalog
(http://java.sun.com/j2se/1.5.0/docs/api/java/sql/Connection.h
tml#setCatalog
(java.lang.String)) on the connection returned from the pool.
One doesn't typically add new database servers on the fly,
and this option would require defining a new JNDI datasource
for a new server. Of course all catalogs processed in this
way must be accesible to the user specified in the
connnection pool properties. I would suggest setting the
defaultCatalog property as well, so that you are not
accidentally connected to the last-used catalog from the
previous borrower of the connection.
Tim
Tim - If you could educate me on an aspect of this, I'd hugely appreciate
it...
What part of the standard set of calls for making a JDBC connection is the
part that sets up the connection?
Normally, all the tutorial stuff shows something like (assuming the Tomcat
JNDI stuff is set up in context.xml):
Get a context
Get a datasource
Get a connection
Make the statements
Close resultsets
Close statements
Close connection
Is there a part of this that takes a lot of time? Part of what I need to do
is handle database calls in a couple of different places (at least in the
current design, which I'm the first to admin is likely not optimal). So that
means figuring out how to get at the database in an effective manner as far
as performance goes. I've seen a number of references to setting up a
connection takes a long time - I'm not sure which of the calls is the part
that takes a long time.
Thanks...

RE: Setting up connection pools on the fly...
Got it. If you only need connections, you can write your own provider class which returns connections (or DataSources) based on a name-to-database mapping of your chosing. Or, if you really must provide each connection as a JNDI DataSource, I would investigate writing your own JNDI provider that operates on the single, manual connection, and returns DataSources based on the information found via that connection. You can borrow some code from javaranch.com's jrunittesthelper, a package which provides JNDI lookups for JUnit test cases.

Hi Tim, Thanks for the assistance. Our basic requirement is during tomcat load/start-up to query the database (with a single manual connection) and read the available database environments that have been pre-configured. Then create these dynamically so they are available as if they had been configured within conf/../context.xml etc. I managed to get this kind of working buy rewriting the config details during start-up but it seems at this time it's too late for Tomcat to use these (i.e. the connection pools are already set up). They would become available the next time tomcat was restarted... I then tried adding the config files as a 'watched' resource but this lead to some strange behaviour. While in most cases we don't change servers as such - we do provide our own tools to manage the database details such as username, password etc and these need to updated without modifying the config files directly.

Rob -Original Message- From: Tim Lucia [mailto:[EMAIL PROTECTED] Sent: 22 January 2006 14:21 To: 'Tomcat Users List' Subject: RE: Setting up connection pools on the fly... The point of connection pooling is to eliminate the overhead of setting up and tearing down a (TCP, database, AAA) connection for every database transaction (typically, the web request in a web app.) This can add 100s or 1000s of milliseconds to every request, and is quite expensive. If you can architect your application so that there is a JNDI data source for each server (database server, instance, etc.) with its own pool of connections, you can always call setCatalog (http://java.sun.com/j2se/1.5.0/docs/api/java/sql/Connection.html#setCat alog (java.lang.String)) on the connection returned from the pool. One doesn't typically add new database servers on the fly, and this option would require defining a new JNDI datasource for a new server. Of course all catalogs processed in this way must be accesible to the user specified in the connnection pool properties. I would suggest setting the defaultCatalog property as well, so that you are not accidentally connected to the last-used catalog from the previous borrower of the connection.

Re: multihoming examplified
I've generally found that I only need one Host element in the server.xml file. The Magic is in the Catalina/hostname/ROOT.xml file.

Context docBase=/Users/kurt/sandboxes/myapp/webapp path= reloadable=true Parameter name=serv1 value=custom1 override=true/ /Context (you don't need that Parameter line- thats a custom parameter for my application) so if you put a directory in Catalina like: Catalina/www.myhost.com/ROOT.xml ...and made that ROOT.xml look like: ?xml version='1.0' encoding='utf-8'? Context docBase=/Users/kurt/sandboxes/myapp/webapp path= reloadable=true/ ...it would most likely work. I've also put Alias directives into the Host section of my server.xml like this: Host name=localhost appbase=/Users/kurt/sandboxes/myapp/webapp Aliaswww.blah.com/Alias /Host ...requests to www.blah.com will also get sent to that localhost context.

How to diagnose a TomCat hang?
Thanks to Tim Lucia I found the solution to my problem. In case any one else gets this problem here's the answer. Problem Briefly: Is there anyway to figure out what TomCat is doing, or trying to do, when it hangs and does not respond to any http or https request? Problem Details: I am running Tomcat 5.1.12 on Redhat9 on a 4 processor server. I get frequent but random Tomcat hangs. It has not happened on a 1 processor system, with either Linux or Windows. I can force the hang to happen fairly reliably if I run tests to bombard the server with http requests (several per second). According to logs it happens after the end of processing one request and before the beginning the next. It is apparently not within application code, unless it's a finalizer. I have run a higher priority daemon thread in same JVM that just writes the time to a log file, and it hangs at the same time, so it could be the JVM that's hanging, or whatever does the real threading. Mostly, but not always, 'top' shows the 'java' process using 99.9% of CPU, and 2 of the 4 processors at about 40%. I can kill the java process with 'kill -9', but I can't figure what it was stuck doing. Any suggestions? Answer: The linux command 'kill -QUIT pid' dumps the state of the JVM to catalina.out which shows, for example, where you are in your code if it is in an infinite loop or a wait-deadlock. kill -QUIT does not actually stop Tomcat. (You find the pid of tomcat to use in 'kill -QUIT pid' using the command 'ps -ef | grep java' which gives output like this: root 30625 1 0 Jan22 ?00:10:00 /pgm/java/bin/java -Djava.util.logging.manager=org.apache.juli.ClassLoaderLo gManager -Djava.util.logging.config.file=/data/tomcat/conf/logging.propertie s -Djava.endorsed.dirs=/pgm/tomcat/common/endorsed -classpath :/pgm/tomcat/bin/bootstrap.jar:/pgm/tomcat/bin/commons-logging-api.jar -Dcat alina.base=/data/tomcat -Dcatalina.home=/pgm/tomcat -Djava.io.tmpdir=/data/t omcat/temp org.apache.catalina.startup.Bootstrap start root 11354 11056 0 08:30 pts/100:00:00 grep java The pid is 30625 in this case - so the command is 'kill -QUIT 30625' ) If kill -QUIT does not write stuff to catalina.out, the JVM is hung. This was my problem, and the cause was a kernel SMP threading bug. I switched from Redhat 9 (2.4.20 kernel) to Fedora Core 4 (2.6.11-1.1369_FC4smp kernel) and have now run for 48 hours without a hang. Changing LD_ASSUME_KERNEL also made a difference. See the tomcat release notes ... #GLIBC 2.2 / Linux 2.4 users should define an environment variable: #export LD_ASSUME_KERNEL=2.2.5 # #Redhat Linux 9.0 users should use the following setting to avoid #stability problems: #export LD_ASSUME_KERNEL=2.4.1 On Redhat 9 running on the 4-way SMP, LD_ASSUME_KERNEL=2.2.5, or nothing at all seemed to be more stable than the recommended LD_ASSUME_KERNEL=2.4.1. I am current running Fedora Core 4 with LD_ASSUME_KERNEL=2.2.5 and it seems to be stable. Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
problem with tomcat 5.5.9
Hi, We observed that tomcat's memory footprint (not the heap size) keeps increasing if we run it for a long time under constant load. Initially it was 305 MB, but after running it for 12 hours continuously, it increased to 1153 MB. We are running the server on Red Hat Linux AS 3.0. We are using Tomcat version: 5.5.9 and we checked that the application is not the cause for memory leak (checked with Jprobe Profiler). Is this a known problem? Any solutions?

Tomcat 5.0.5 threads + log4j Mapped Diagnostic Contexts. Simultaneous clients access problem.
Hi folks, here is a description of the current situation we have releasing the logging component. Prehistory: Using the log4j mapped diagnostic context dump the application specific information into the log files. Details: http://logging.apache.org/log4j/docs/api/org/apache/log4j/MDC.html The log4j documentation has a primary statement that is accordingly the basis for the MDC/NDC approach: In a typical multithreaded implementation of such a system, different threads will handle different clients. History: As the test environment apache 2.0.49 and tomcat 5.0.25 under windows 2000 professional were used. The tests showed that two clients not necessarily become the different threads. Quite often the thread, taken by the client A is shared later with the client B and afterwards is used again by the client A. Questions: I`m wondering how it is at all possible, does it mean that tomcat has somewhere the pool of the actual HttpSessions and they are not associated with the corresponding threads or even worth it makes the session serialization and gives another client the control over the thread? Due to my tomcat configuration I do not see any restrictions on the thread pool, in many times the client even opens the several threads and this is understandable. The non-understandable is the thread sharing between several clients and valid HttpSessions. I believe it is pure tomcat issue, that’s why stated the question here. The ideas and suggestions are highly appreciated, Yefym.

Hi, sorry for my question, but I'm googling, reading manuals and still no answer... So. The question si very simple: How can I ommit the servlet name in the URL? Ex.: I have http://localhost:8080/ServletTest/path_in_the_servlet_and arguments and I need http://localhost:8080/path_in_the_servlet_and arguments I will run under Tomcat only one servlet; and I want to handle all the domain.

Capturing JNI DLL printf()s to Tomcat logfile
Hi All, I want to be able to capture the printf()s in my JNI DLL to a logfile in Tomcat. I'm using jakarta-tomcat-5.5.9 and Java 1.5 on Windows XP. I'd rather use something that's built-into Tomcat.. Commons Logging or the JDK logging. Something simple if there is such a thing.. If I have to go with Log4j to do it, that's okay. There HAS to be some kind of way to do this.. :-\ Thanks, Joe Siebenmann __ Do You Yahoo!? Tired of spam? Yahoo!

ok, the start of this thread got lost... let me try and do a brief
refresher...
I'm working with Tomcat 5.0, Apache 2, and a whole bunch of servlets that I
inherited. The website is a combination of static HTML and java. 95% of the
java code is implemented in servlets (that write out the dynamic HTML) and
NONE of the Java code is in packages.
The HTML on the site, when referring to servlets, uses relative paths like
form action=../servlet/servlet-name. In order to remove the invoker
servlet, I need to map all the servlets on the site through a web.xml file.
Initially, I was getting a resource unavailable error from Tomcat, but it
now appears as if my servlet mapping was wrong. (my app lived in the
${catalina.home}/webapp/servlet directory, and my web.xml was mapping a
servlet to url-mapping/servlet/[servlet-name]/url-mapping.
I fixed this by removing the '/servlet' in the url-mapping tag, and I now
get a stack trace with a ClassDefNotFound [servlet-name] error. This error
occurs when I point at Tomcat directly, so I know the error has nothing to
do with Apache. I now have a stripped down web.xml file that looks like this
(minus the xml and DOCTYPE directives):
...
web-app
servlet
servlet-nameFLCUpEvDisplayServlet/servlet-name
servlet-classFLCUpEvDisplayServlet/servlet-class
/servlet
servlet-mapping
servlet-nameFLCUpEvDisplayServlet/servlet-name
url-pattern/FLCUpEvDisplayServlet/url-pattern
/servlet-mapping
/web-app
Now everytime I hit the servlet, I get the ClassDefNotFound error, and
after that I see an entry in the log file:
2006-01-23 11:35:53 StandardContext[/servlet]Marking servlet
FLCUpEvDisplayServlet as unavailable
2006-01-23 11:35:53 StandardContext[/servlet]Error loading WebappClassLoader
delegate: false
repositories:
/WEB-INF/classes/
after which I get a resource is not available error again, until I stop
and restart Tomcat.
So, my question is... why am I getting the ClassDefNotFound error, and how
do I correct it (or can I, given my current configuration)?
Thanks

RE: (newb) Tomcat servlet mapping problem
As an add-on -
I successfully mapped the Tomcat servlet example HelloWorldServlet to my
/servlet directory successfully through my web.xml file. I did this to make
sure that a servlet with no package could be deployed the way I am
attempting (HelloWorldExample has no package). The ONLY error I encountered
while deploying the HelloWorldExample, was it complained that the
ResourceBundle the code was looking for couldn't be found. I recompiled the
servlet without the ResourceBundle code and the servlet worked correctly.
(I wasn't sure how to configure the ResourceBundle in the code. I copied all
the files the resource bundle seemed to be referring to into my /servlet
directory along with the compiled HelloWorldServlet code, but it still
complained on execution that it couldn't locate the resource, so it was
easier for me to comment it out.)
This tells me I can definitely deploy a servlet the way I am trying to, but
it also raises questions about why the resource bundle couldn't be located.
Is all of this really a classpath or class loader issue in some way?

How can I take a webapp temporarily out of service using mod_jk?
Hi I am running a JBoss cluster, using tomcat as the Servlet engine. Apache and mod_jk provide load-balancing of requests over the machines in the cluster I need to be able to replace all the URLs in the webapp with a Temporarily out of service page during maintenance, and I need to do this without making any permanent Apache configuration changes and without restarting Apache (Operations is very reluctant to restart Apache). Does anyone know a way to do this? I think there may be a way to use the controls on the mod_jk status page to redirect all requests for a webapp to a different URL ( the Route Redirect input) but this is probably wishful thinking - even if does allow me to redirect requests, it would probably apply to all the webapps in the cluster, which wouldn't meet the requirement. The status page teases me by listing all the JkMounts and JkUnmounts, but doesn't allow me to change them; adding a JkUnmount dynamically would be a good solution. Any Ideas?

RE: (newb) Tomcat servlet mapping problem
Georg,
if I look at your original configuration
servlet-mapping
servlet-nameSimpleServlet/servlet-name
url-pattern/simple-servlet/url-pattern
/servlet-mapping
---snip---
Context path=/simple-servlet docBase=SimpleServlet
reloadable=true debug=99
then, if I am not overlooking something,
the correct URL to invoke the servlet is
http://localhost/simple-servlet/simple-servlet
because the first simple-servlet is the
Context path where the webapp resides, and
the second simple-servlet is the URL for
the servlet inside the webapp, like correctly
configured in the webapp descriptor.
You are correct. I realized this yesterday while playing with this problem.
I've since removed my servlet.xml file that contains the Context tag
specifying the docBase and path.
I've gotten over this hurdle and immediately gotten hung up on the next one.
=P The only file I'm using for mapping the servlet now is the web.xml file
in the ${catalina.home}/webapps/servlet/WEB-INF directory.
The new issue is ClassDefNotFound that occurs when I point my browser at
the servlet (see last message, because I'm not retyping that 'brief' recap
again).
Thanks, though. I do appreciate the help.

Since your in a cluster, you have the problem of replicating this out of service flag to all the nodes... a database would be the obvious answer, but clearly that has performance implications.

They would become available the next time tomcat was restarted... I then tried adding the config files as a 'watched' resource but this lead to some strange behaviour. While in most cases we don't change servers as such - we do provide our own tools to manage the database details such as username, password etc and these need to updated without modifying the config files directly.

The point of connection pooling is to eliminate the overhead of setting up and tearing down a (TCP, database, AAA) connection for every database transaction (typically, the web request in a web app.) This can add 100s or 1000s of milliseconds to every request, and is quite expensive. If you can architect your application so that there is a JNDI data source for each server (database server, instance, etc.) with its own pool of connections, you can always call setCatalog (http://java.sun.com/j2se/1.5.0/docs/api/java/sql/Connection.html#setCat alog (java.lang.String)) on the connection returned from the pool.

Of course all catalogs processed in this way must be accesible to the user specified in the connnection pool properties.

Hi all... I haven't been posting JWP release announcements here lately, and generally I will refrain from doing so, but the team just put out a new release last night and I think it has some features that might be of interest to many of you... * AjaxTags now has some new capabilities, including the ability to have multiple config files, the ability to have static parameters on the target URLs, a built-in debugging facility and an implicit passing in of the ajaxRef with each request, so now you can always determine which element fired the event. * The Chain implementation now supports loading config files from JAR files, and there is now a SimpleCommand that you can extend (instead of implementing Command) that has default implementations of all three Command methods (init(), execute() and destroy()), so you can only worry about the ones that interest you. * A new popup calendar widget has been added to the UIWidgets taglib. * JSDigester was added to the JSTags taglib. JSDigester, as you may be able to guess, is a client-side implementation of our beloved Commons Digester. It is not as full-featured as it's big brother, but it can come in *very* handy, just like the full-fledged Digester. Take care! -- Frank W.

Your code does not really get serialized.

For many of your custom object types it may be as simple as just implementing the Serializable interface. But if any of your objects have database connection, or other information that cannot be readily serialized - this will take a bit more thought. I'm not aware of a tool that would do this for you - it would be magic :) When I moved an application to a Tomcat cluster a while back, it turned up a number of objects that I did not realize were Serializable, including Log4J loggers. It took a bit of rework, but probably was all done within a half of a day.

Is there any ready-made tool which does the job easily? Otherwise, manually, how can i convert my existing code into serialized format?

RE: problem with tomcat 5.5.9
Hi, Small update on the problem mentioned We did not found any memory leak, but memory footprint is increasing. We observed that tomcat's memory footprint (not the heap size) keeps increasing if we run it for a long time under constant load. Initially it was 305 MB, but after running it for 12 hours continuously, it increased to 1153 MB. We are running the server on Red Hat Linux AS 3.0.

We are using Tomcat version: 5.5.9 and we checked that the application is not the cause for memory leak (checked with Jprobe Profiler). Did the profiler indicate any memory leak? If so where was it?

RE: serializing java code
I do have objects that do db connections. I think i would need to dig out some more info into the direction you provided. I will look out for how to do it and work upon. Thank You.for providing useful information !!

You just have to be sure that you are not storing any objects in the Session that are not Serializable - i.e. they must implement the interface java.io.Serializable.
