Logging exceptions per webapp in Tomcat 5.5

[Svein Olav Bjerkeset]

After having read about how to setup logging in Tomcat 5.5 
(http://jakarta.apache.org/tomcat/tomcat-5.5-doc/logging.html),
I have managed to set up Log4j to work with Tomcat 5.5.

However, when I set up indivdual logs for my webapps, only output generated 
from log statements in the code (Log4j
statements) end up in these logs. Exceptions still end up in catalina.out 
(which is common to all webapps). I would
like the exceptions to end up in the logfile belonging to the webapp that 
generated it.

I have tried adding the following line in my 
web/WEB-INF/classes/log4j.properties file without getting the wanted result:

log4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/mywebapp]=DEBUG,
 A1

To test the logging, I have written a short JSP which just thorws an exception. 

>From what I read in the following article: 
>http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg143230.html,
it seems that exceptions (and other output sent to stdout or stderr) can not be 
redirected and will always go to
catalina.out. Is this correct or is there a way to also redirect exceptions to 
individual log files basen on what
wabapp generated the exception?

Thanks in advance for any help,
Svein Olav Bjerkeset

You could use iptables to redirect the port

As an aside, given that Tomcat now does not use the Sun javac compiler
but instead the Eclipse compiler (which is open source) why did you feel
the need to replace the compiler with the kaffe one?  Its a useful exercise
to know it can be done, but I am not quite sure why you wanted to do it?

global variables inside a Tomcat JSP-Servlet app.

[Ben Bookey]

Dear List,

I hope someone can give some hints to a none java/TC -specialist.

We have a jsp-servlet app, which has some important app variables inside
the web.xml. Because the validation for these parameters is quite complex
we have a single public class with public static setters and getters
available to the all servlets and jsp pages within the application.
We use a context listener to read the parameters, so we can initalise this
public object reading the web.xml

This works fine but  I was wondering if there is a better way of doing this
?  Would appreciate any
comment. We are using TC 4.0 and 5.0

regards,

Ben

Re: Re: JSP compilation problem

As QM mentioned, Tomcat 5.0 doesn't support Java 5.0 "out of the box", so to 
speak. I believe there's a patch you need to make them play nicely. Tomcat 5.5, 
as he pointed out, is very tight with Java 5.0.

This is the quirky part about Tomcat, in version 5.0 or ealier, I have
to use this xml code in my webapp context file for DBCP.




factory
 
org.apache.commons.dbcp.BasicDataSourceFactory


url

jdbc:jtds:sqlserver://192.168.0.2:1433/summitexec;User=someuser;P
assword=somepassword


driverClassName
net.sourceforge.jtds.jdbc.Driver


user
someuser


password
somepassword



In 5.5 I have to use this xml for DBCP.  If someone could provide
details why this is, I would appreciate it.

 

Thanks,

Randall

Subject: Speed issues with SQL Server 2000 and JTDS

I bought the Core Servlets and Java Server Pages and read it over the
weekend.  Happy New Year to me.  I did get out to a few parties though.
;)  I am having trouble getting JTDS to return results quickly. 
 
Has anyone got any example code for how to properly query a SQL Server
2000 database?  The code I write needs to work with both SQL Server 2000
and SQL Server 7.  In creating the connection, I am specifying
TYPE_SCROLL_INSENSITIVE and TYPE_CONCUR_READ_ONLY.  I tried not
specifying anything and got errors about not being able to scroll the
results.  Is the only solution to this, use FORWARD_ONLY and buffer the
contents myself?  I hoping there is a better way.
 
Thank you
Charles Killmer

You could try using something like jProfiler to see where the bottleneck
is. 
 
I don't see anything unusual in your code example, although it looks
like the only thing it does is create the connection. I use jTDS and it
works fine without doing anything exceptional.

using Thread object in Tomcat

[Mark]

Hi,

I'd like to check if it a good way to implement user's notifications
using Thread object?

What I would like to do is to have a singleton object (extends
Thread) that will "wake up" every minute and do something( let's say
go to data base, take to another 3rd-party system, etc) and once the
condition met will populate static  variable in another class which
will inform ( display in JSP) ALL users about THAT event ?

Thanks,
Mark.

Re: using Thread object in Tomcat

[David Boyer]

Rather than creating a class that extends Thread you should create a
class that implements Runnable and construct a new Thread using your
Runnable. You'd extend Thread if you were adding some extended
functionality to the Thread class, otherwise use Runnable.

Re: How Do I Install A Valve

Thanks for the advice.  I had originally put my class in 
org.apache.catalina.valves to avoid any problems with access to protected 
fields and methods.  After reading your reply, I studied the Tomcat classes 
and determined that there would be no problems.  So, I have moved my class 
to my own package, bundled it into a jar, and put it in 
CATALINA_HOME/server/lib.  Works like a charm!

Benson Margulies wrote:
To begin with, unless you are planning to submit your valve as a patch

Since Valves run inside the server, not inside the web app, they need to
be in the server classpath. You can either do what you did or edit
catalina.properties.

Through some trial and error, I solved the problem.
The class file apparently needs to be under
CATALINA_HOME/server/classes. 
If one bundles it into a jar file, the jar needs to be in
CATALINA_HOME/server/lib.

I'm real new to Tomcat, so I don't know if this is really the place to
put it.  Is there anyone who can advice on "best practices"?  Is there a
better (or another) place to put this valve?

Disable PUT and DELETE HTTP methods

[Mark Anderson]

Last month, someone asked how to disable the HTTP methods PUT and DELETE. 
(I wasn't on this list at that time, so I can't reply in a threadly manner.)

I wrote a valve to accomplish that.  I won't clutter this list with my 
code, but I will say that I simply wrote a class that extends 
org.apache.catalina.valves.RequestFilterValve.  If you want the code, just 
drop me a line.

Tomcat 5.0.28 running Windows 2003 Server CPU to 100%

[David Bilodeau]

Can anyone point me to a thread discussing 
the following configuration or something similar, where the discussion relates 
to the CPU running up to 100%?
 
Windows 2003 Server Standard Edition running 
IIS 6.0
Tomcat 5.0.28 installed and running (as a 
service)
SQL Server 2000 SP3 connected to Tomcat (and 
IIS), but running from another server.
 
Our symptom is that after a few days the 
server CPU usage hits 100%, with Tomcat consuming most of it.  
Stopping and restarting each Tomcat virtual site, or stopping & restarting 
the Apache service does not resolve the issue.  Only a box reboot 
will.
 
I need some guidance as to where to suggest 
to the developers they should look, presuming this is caused by the code.  
I am the system admin of the environment and so do not develop the code myself, 
but I am seeing this symptom and now need to ask the developers to examine their 
code to find a root cause.
 
I bet someone, somewhere, has run across 
this on a thread on this forum and can point me to it?  I've been searching 
some but have not found much yet that is recent.

RE: Tomcat 5.0.28 running Windows 2003 Server CPU to 100%

[Mike Curwen]

Every so often in our development environment, we'll have a page that goes
off in an infinite loop.  No problem, we'll just stop the browser, and fix
the page and click refresh.  But meanwhile, that first page is still
spinning away, gobbling up CPU.  
 
I once saw code on tomcat-user that allowed me to see what each thread was
doing. It's at the very bottom of this post:
 
http://marc.theaimsgroup.com/?l=tomcat-user

&m=109455426721082&w=2
 
I must have found the 'second part' from somewhere else, probably
tomcat-user as well! It's a filter that renames the thread to be the JSP
page that the thread is processing:
 
public void doFilter(ServletRequest servletRequest, ServletResponse
servletResponse, FilterChain filterChain) throws IOException,
ServletException {
 
 Thread t= Thread.currentThread();
 String oldName = t.getName();
 HttpServletRequest request = (HttpServletRequest) servletRequest;
 try {
  t.setName(oldName + " - " + request.getRequestURI());
  filterChain.doFilter(servletRequest, servletResponse);
 } finally {
  t.setName(oldName);
 }
 
}
 
combining those two, and you'll get what page is currently processing on
what thread.  If you see the same page for more than  (the time varies,
but let's say 10 seconds)...  then perhaps that page is 'dead' and is
consuming your CPU.

heap size params on linux

[Stephen Charles Huey]

Our script for installing Tomcat as a service on Windows is down below. 
We're moving to Linux, so I'm wondering where we specify the heap size
parameters (-Xmx and -Xms) for the Tomcat on Linux.  Would the correct
place be in the startup.sh file?  Thanks!


D:\tomcat\bin\tomcat.exe -install "Apache_Tomcat"
"C:\j2sdk1.4.2_04\jre\bin\client\jvm.dll" -server -Xmx1536m -Xms1536m
-Djava.class.path="D:\Tomcat\bin\bootstrap.jar"
-Dcatalina.home="D:\Tomcat"
-Djava.endorsed.dirs="D:\Tomcat\common\endorsed" -start
org.apache.catalina.startup.BootstrapService -params start -stop
org.apache.catalina.startup.BootstrapService -params stop -out

Re: heap size params on linux

[Stephen Charles Huey]

I see that JAVA_OPTS is mentioned in there quite a few times, so where
exactly can I put set JAVA_OPTS=-Xmx1536m?  Also, do I need to do both
the initial and max in one line?

E.g.  set JAVA_OPTS= -Xmx1536m -Xms1536m (with nothing on the end of the
line?)

Does the -server option go with JAVA_OPTS as well?

Thanks...

Re: heap size params on linux

[Rodrigo Schmidt]

I think that any option you want to pass to the jvm can be placed in 
JAVA_OPTS, like this:

set JAVA_OPTS = "-Xmx1536m -Xms1536m -server"
I do that and it works fine.

You don't want to use the 'set' statement in catalina.sh.


Here's an exerpt from mine:

 #
 # $Id: catalina.sh,v 1.13.2.2 2004/11/17 20:06:34 yoavs Exp $

#-

 JAVA_OPTS="-Xms128m -Xmx128m"




Then just go to the HTML Manger and click "Server Status" to verify that
it took.

Context for User development accounts??

[Dwayne Ghant]

I must have missed this answer in my readings
some where. I have an easy question concerning the
context container.
I have configured tomcat to read
all user account on a local machine and it worked,
but if I don't put a context in the
server.xml file for "/~username,"
then how does it get loaded and sence it seems
to be loading automatically then
how can I set reloadable="true" of I can't find
the context
Your assistance will be much appreciated.

web.xml servlet mappings, url pattern and CGI.PATH_INFO (tomcat 4.1.31)

[Jack Eidsness]

I am new to the J2EE world, so hopefully I will not use terms incorrectly.
Due to circumstances beyond my control, coldfusion has been retrofitted 
into a J2EE web application and I have recently taken on the task of 
trying to make previously existing cfm code work as part of a tomcat 
installation.   I have found (so far) only one thing that doesn't work 
like it used to, and its a significant problem for me.

CGI apps can have a false path appended after the script name, which is 
written into the CGI.PATH_INFO variable, so that it can be available to 
scripts.  It would seem that tomcat is less flexible than apache httpd 
about when this information will be supplied.  At least, jakarta-tomcat 
4.1.31 doesn't want to play ball.  I have not yet experimented with 
version 5.x.

I have found a lot of discussion of this matter, but no conclusive 
answer as to what the workaround is, nor, as i fear, that there is no 
viable workaround.

By default, my coldfusion war file came with this in the web.xml:
  
 CfmServlet
 *.cfm
  
attempting to browse (via the coyote thingie) to
http://{server}/cfusion/htdocs/index.cfm
will bring up the right page, but
http://{server}/cfusion/htdocs/index.cfm/fake_path
this gets me a 404.
So far, I have only found one way to make tomcat give me the correct 
PATH_INFO -
If I do this:
	/htdocs/index.cfm/*
then I will be able to run the right script and CGI.PATH_INFO is set to 
"/fake_path".

Naturally, if you have more than a couple situations where you use 
PATH_INFO, this configuration becomes quickly unmanageable, and 
unreasonable.  ("grep -iRl path_info ." will only get me so far)

Is there a way to make this work without naming every cfm file that 
might use PATH_INFO in the web.xml?

For anyone interested in helping, here are some things that I have tried 
that did not work (in each case, I have tried it as a replacement, 
breaking the normal way it works for possible experimental value, or as 
an additional servlet-mapping):

If I do this:
 *.cfm/*
I get an error in the jakarta logs when the web.xml is read;
java.lang.IllegalArgumentException: Invalid  *.cfm/* in 
servlet mapping

I looked up the source code and it says you can't start a servlet 
mapping's url-pattern with "*." and have a "/" in the pattern at once. :/

If I do this (nevermind that its not exactly what I want):
	*.cfm*
Then the second * is not expanded as a wildcard. i.e. a file named 
"index.cfm*" (literal '*' character) could be processed as a cfm file.

If I do this
/*.cfm/*
I get a 404.
Thanks in advance for any time that any of you spend considering this issue,

Re: web.xml servlet mappings, url pattern and CGI.PATH_INFO (tomcat 4.1.31)

[Parsons Technical Services]

I am sure there is a better option out there but if no one else weighs in, 
here are a couple of thoughts.

As for the wild card I know there are several threads addressing the do and 
don't of this. Although I think you have figured them out through trial and 
error.

As for one way to approach this would be to map the appropriate files (any 
with data) to a servlet that could parse the file name and pass the request 
on to the appropriate file. As I am not familiar with cgi stuff, I may be 
missing something.

files directly.  It's quite easy to write a wrapper script that sets
needed environment variables in such a way that catalina.sh will find
them.  For example:

[excerpt of wrapper script]


. ${CATALINA_BASE}/conf/container.rc

...
case $1 in
'start')
${CATALINA_HOME}/bin/startup.sh
;;
...

[excerpt from container.rc]

export JAVA_HOME=.
export JAVA_OPTS=

-QM


[1] = for the archives: "set JAVA_OPTS in catalina.sh"

If there's no  element (neither in server.xml, nor
context.xml) but loadOnStartup=true, then Tomcat loads all contexts with
reasonable defaults.

Solution: create an explicit  element for the context and
configure it to your heart's delight.

If I've misunderstood your question, please elaborate =)

Defining application Global properties.

[haim]

I would like to set up some application global properties.
I would like those properties to be available application width, and 
should be loaded as soon as the application loads no mater witch page 
was visit.
I guess I have few options for that , which one do you think is the best 
practice?

 1.  Using the  , but those are servelt related and not
application related ?
 2. Using java properties file , but now I need some one to load then
at server startup ?
 3.  Any other good Idea that you may think of?
Thanks
P.S. Does any one know why the search list page is not working?
