For the OOM error - you might want to add compile=false to your jsp2 task so compilation is not done.

Warnings filing my event viewer with shm file creation errors
Hello Tomcat Users, I have a Tomcat 5.0.27 installation on a Windows 2003 Server. Tomcat is setup as the servlet container for the IIS 6 instance on my machine.

However, the shm file is created and its modfication time has changed since these warnings were logged. If Access is denied as the error states, then how can the shm file exist? I would like to try to fix these warnings from occurring and filing up my event viewer log. I receive these warning several times a day. My workers2.properties file defines the shm section as: [shm] file=d:/Tomcat5027/work/shm.file size=1048576 Thank you in advance, -Aaron

Re: Internationalization Problem with Tomcat 5.5.9
IMO, it's quite possible that your webapp were relying on bugs in previous version. So, you have to make sure you're jsp pages are following standards. The obvious reasons that I could think of are the followings tags not being used correctly: 1. %@ page contentType=text/html;charset=utf-8 % This tag specifies in which encoding your _resultant_ webpage is using. It's in UTF-8 in my example. 2. %@ page pageEncoding=iso-8859-1 % This tag specifies in which encoding your _original_ jsp file is saved. It's in ISO-8859-1 in my example. If your editor can't save in other encodings than your system's, I would expect that you're using the same encoding here. 3. meta http-equiv=Content-Type content=text/html; charset=utf-8 This tag, which is within HTML head tag specifies once more to the browser in which encoding it should use to render the page. Its encoding HAS to be the same as that specified in no 1 (UTF-1 in my example). Some might argue that this is not necessary, but the fact is that there're still browsers out there not capable of parsing encoding info in HTTP header.

Re: problem loading class in TomCat
Are all your classes in a package? Mark Camila Kozlowski Della Corte wrote: Greetings, I am developing an application with JSP, and using JSF. Here is a description of the problem I had with TomCat. I created a class A which invokes a class B. This class B invokes a class C (class C is a JUnit class). Both the jar files containing class B and C are located in the lib folder of my JSP application (the jar file containing class C is JUnit.jar). When I run my JSP application which uses class A TomCat does not load the JUnit class, and shows the following error message: java.lang.NoClassDefFoundError: junit/framework/TestCase When I run class A as a Java application it works perfectly. I tried many things but TomCat does not find this class. I have tried putting the uncompressed classes inside the application classes folder but I get the same error message. My last trial was to directly call class B of the JSP application, but I get the same error message. Class B (which invokes the JUnit class) uses reflection in the implementation. Is this a problem for this context? I would like to know if anyone knows what is going on and why I get this error message. I would appreciate if anyone can give me a clue to solve this problem.

Re: Critical problem with Tomcat worker threads
Hi, We are experiencing similar problem. Just the Thread gets stuck for random period time (between 1 and 15 minutes) after also random period of time. For some reason its always in jdbc driver.

Can anyone give suggestions on Best practices for Farmwardeployer in a tomcat cluster??
I'm just new to HA environments, we were able to do Apache / Tomcat Load Balancing through AJP13. Though there were few concerns on fail overs and session information, so we tried clustering tomcat servers. Everything went well and working as of the moment, I know that clustering is just like playing with fire. Without extensive knowledge could be detrimental overtime. May I ask anybody who's implemented such architecture for a best practices guide for this with the utilization of Farmwardeployer. Small concern on farmwardeployer, if the farmwardeployer server went down and was started up again. It always reloads all the application on the watchedDir path to the entire cluster. Is this normal, or we can do something about this to avoid such delays.

Re: Question concerning java.lang.NoClassDefFoundError: javax/servlet/ServletContext
NoClassDefinition errors are normally thrown if the class or JAR isn't
in the classpath, the only other time this happens is when the
ClassLoader isn't able to load the class path because an exception is
thrown on any static initialisers.
(This is conjecture...) It may be the ServletContext has a static { ...
} block that is throwing an error for some reason, the class can't be
loaded and is therefore not available, hence the NoClassDefinition
found error.
However, I don't understand why your code is moaning about
ServletContext when it doesn't look like you are anywhere near it.
Kind Regards,
Chris.

What's the difference between .zip and .exe from download site?
Hi, there: I tried both .zip and .exe to install tomcat on my Win2000 box. It seems that for .exe: a. it installed Tomcat as win service; b. it also created some registry keys about TomCat version, etc. (Which is critical, I guess, for other applications to check TomCat version, right?). Anything else besides? So, then what is that .zip download for? In which scenarios we should use .zip instead of .exe to install TomCat on Windows system? Thanks a lot David

My plan is to try:

That way there should only be one servlet.
I am writing a servlet to save grades to a database, but,
unfortunately, instructors will procrastinate like students do. So, I
expect that 2000+ instructors will submit their grades in the last hour
or so, before the deadline. If each instructor had their own db
connection then the system will be useless, as students won't be able to
get connections, since all the connections will be used up.
For the first test I want to limit them to only one connection that
will read from an input queue, and just process all the grades. Later it
may be bumped up to 20-50 connections, to speed it up.
That is the basic problem I am trying to solve.
I am actually using XmlHttpRequest to connect to the servlet so it
doesn't lock up the browser.

You can't use the modifier static there (only with internal classes).
That way there should only be one servlet.
My rereading of the spec shows there will be only one servlet, unless
you have a distributed environment. However, there will be multiple
concurrent requests utilizing the same servlet instance. You can
control the amount of concurrency with the various thread-oriented
attributes of the Connector tag. Attempting to limit concurrency to
one is unrealistic.
The Tomcat doc covers that as well as configuring database connections.

Re: Question concerning java.lang.NoClassDefFoundError: javax/servlet/ServletContext
Thank you for your comments thus far.
I have been unable to solve my problem as well. I even went so far as to
start with a machine with no development tools on it, downloading just the
elements I required, and then trying to redeploy. I am fairly certain that
there are no extra servlet jars anywhere, and that servlet-api.jar from
tomcat is in the path. Still I face the java.lang.NoClassDefFoundError:
javax/servlet/ServletContext error. I am using java 1.5.0_06 and and a 5.5
server. Well, trying to anyway! =) I'll place the error information at
the very bottom of this email to avoid pushing down the previous responses
too far. Any more ideas would be appreciated!

Hello David,
I included all jar zip files on my computer, including j2ee.jar and I'm
still having the problem.
I have just noticed a weird behaviour though, if I try to reload the jsp
right after the jsp fails the first
time it seems to run without throwing the exception. If I restart Tomcat
and try again the problem starts
again. I could get this to work in theory by forcing it to run through
the
code once on startup
but I shouldn't have to do that and I honestly would prefer getting it to
work as it should.

I'm using java version 1.4.2_10
The code i'm using used to work under Orion version 1.4.5 (I'm now using

The code that eventually throws the exception is basically:
ClassFinder classFinder = new ClassFinder();
classFinder.addFile(/opt/classes/com/canlink/commands/);
Class usrClass = classFinder.findClass(com.canlink.commands.TestClass);
This line is what throws the exception:
Method setCmdLog = usrClass.getMethod(setCmdLog, new Class[]
{Boolean.class});

re: making a singleton servlet
If you deploy your servlet with an application deployment scope, you will have just one instance of the server classes instantiated. Multiple clients can still call into your web service, but you have to make sure that your member data is thread-safe. James Black [EMAIL PROTECTED] wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I am going to make my servlet be static, with the hope that it will only have one instance running, regardless of how many clients connect to it. My concern is what happens when two clients try to connect at one time. Will the second client block, until the servlet is available? I am planning on having it be multi-threaded to handle several clients, but I was just curious if the client will block. I only want one instance because I want to control the number of database connections, and right now the magic number is one db connection. I will just queue up the client updates and there will be a mechanism for them to be informed when the db update is completed. Thank you. - -- Corruptisima republica plurimae leges.

Re: making a singleton servlet
The problem you are trying to solve is not propely solved by trying to
limit the container to a single servlet instance (which you probably
cannot control anyway, unless your container allows some sort of
proprietary setting).
The way you should be thinking to solve this problem is a connection pool.
Your servlet needs to be written in a thread-safe manner anyway, and
that allows the same servlet instance to handle multiple requests at the
same time. Having a connection pool underneath that will allow you to
share your database connections efficiently.
There are numerous options for connection pooling... the first thing
you'll probably want to look into is what your container itself offers
in this area. Most containers have some sort of pooling facility
available. Another option is to build on top of a persistance framework
like Hibernate or iBATIS, both of which offer some degree of pooling
support. There are libraries for doing it as well, DBCP (a Jakarta
Commons package) for instance. You could always write your own, it
isn't too tough, but for something that has been done to death you are
definitely better off not bothering.
Of course, since your posting to the Tomcat list, I can tell you that
Tomcat offers such support:

What do you mean by servlet be static? What syntactical construct are
you employing?
If you mean using static fields in your servlet class, then you will
have to make use of synchronization clauses to insure concurrent
requests are serialized. It's my understanding that the container
(Tomcat or whatever) is free to process as many requests in parallel as
needed, as well as create multiple servlet instances - see the servlet
spec.
What problem are you trying to solve?
My plan is to try:
public static class SomeServlet extends HttpServlet { ... }
That way there should only be one servlet.
I am writing a servlet to save grades to a database, but,
unfortunately, instructors will procrastinate like students do. So, I
expect that 2000+ instructors will submit their grades in the last hour
or so, before the deadline. If each instructor had their own db
connection then the system will be useless, as students won't be able to
get connections, since all the connections will be used up.
For the first test I want to limit them to only one connection that
will read from an input queue, and just process all the grades. Later it
may be bumped up to 20-50 connections, to speed it up.
That is the basic problem I am trying to solve.
I am actually using XmlHttpRequest to connect to the servlet so it
doesn't lock up the browser.

changing the webdav root
Has the webdav servlet been updated to allow the dav files to be placed outside of the servlet context? For example I would like to specify the DAV files be placed on /space/dav. There was a thread on this about a year ago but i'm not sure if there was ever closure. Here is the note.. Mark Thomas wrote: The webdav servlet is based around accessing the file system through a JNDI DirContext for the current webapp. I've officially started working on the configured-filesystem-root feature. The ProxyDirContext gets configured either by getting the org.apache.catalina.resources attribute from the servlet context, or the java:/comp/Resources JNDI setting. Question: Which of these is used in the default configuration, and where is that value actually configured? Thanks, Garret
