Virtual hosts and shared libraries

[Oleg]

I got a problem with Tomcat using a huge amount of memory on startup. Of 
course I realize that it all depends on how large are the applications. 
However, I have lets say two identical machines with Tomcat 5.5 installed. 
One Tomcat has 100 virtual hosts running the same application and takes up 
400MB of ram after it finished loading, second Tomcat has 300 identical 
applications but deployed under localhost and it uses only 200MB of ram 
after loading. Can somebody explain me what is the case here? Does it mean 
that virtual hosts load all libraries in shared directory for every host 
into memory but all application running under localhost, simply load them 
once? I am a bit lost, I need to figure something out to cut down on memory 
use, any ideas? All users are running same application, application specific 
classes are in its own application WEB-INF/classes and all libraries needed 
to run the application, like struts and hibernate and so on are in shared. 
Thank you.

Hi,

One way to access database from JSP pages is using connection pool
from JNDI. You can find more information from here:
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-datasource-examples-howto.html

It's a Windows limitation.  Windows normally provides only 2 GB of
virtual address space per process, and this is somewhat fragmented by
various DLLs that are scattered about in it.  The JVM requires
contiguous space for its heap (at least it did in 1.4, haven't looked
inside 1.5 yet), and the biggest chunk it can get is about 1.6 MB.
There is a bootstrap option (sorry, I can't remember the tag) for some
versions of Windows server that allows 3 GB of address space per
process, but it reduces the amount of memory available for kernel
control structures, so there are tradeoffs in using it.  Also, the
32-bit JVM did have a problem with heaps over 2 GB due to sign handling
errors; this may be fixed in current levels (haven't tried it in a
while).

In any event, putting 4 GB on the system will help some, since that
would eliminate the risk of doing any paging, assuming you're not
running much else other than Tomcat.

Limitting bandwidth: Filedownload

[Lars Nielsen Lind]

Hi.

 

Is there a way to make two channels with Apache / Jakarta-Tomcat regarding
to the Internet connections bandwidth?

 

One channel serving jsp, html, gif, jpg, png files, another channel serving
pdf, xls, doc files. Lets say the bandwidth totally are 512 kb is it then
possible to define for instance 384 kb for the first channel and 128 kb for
the last channel, vice versa?

 

The files are physically placed in the filesystem outside of Apache /
Jakarta-Tomcat webapp directory and is fetched with a download servlet
component.

 

Best regards,

 

Lars Nielsen Lind

mod_jk not detecting loss of a load balanced machine

[Edmon Begoli]

We've noticed with two versions of mod_jk we've been using (1.2.5 and 
one older) that if one of the machines
hosting load balanced tomcat gets completely off the network (power 
loss) mod_jk will seem not to emove that one from the load balanced 
instances,
so the whole site will appear down because mod_jk will I guess try to 
hit it. I can not say for sure that it is the reason behind the scenes,
but I can say for sure that these versions of mod_jk do not respond well 
to machine losses - which is a pretty possible scenario.


My question is - has this been addressed in some of the later releases, 
and if not is there a workaround?

Automated Server Configuration (was api for server.xml maintenance)

[Rob Hills]

Hi All,

I received no reply to my earlier email in this thread so I thought I'd try and 
come up with a less verbose description of my problem.

I'm looking to automate the management of hosts on my server.

Our tomcat servers operate multiple applications, each of which has its own 
host entry and root context.  We do this because each application has its 
own domain name and the domain name and root context is an important 
feature for our clients.

I've read the documentation on the Tomcat Manger and the Tomcat 
Deployer in great detail, but as far as I can tell, both only support the 
management of contexts under a previously established host.

I'm also aware of the ability to "auto-deploy" applications by depositing their 
WAR files into the %CATALINA_HOME%/webapps directory.  However, 
these are then associated with a context under the default host, which is not 
what I want to achieve.

I'd thought maybe there I could write a request filter that redirects requests 
for a specified url (domain name + url) to a context in the default host, but 
I'm not even sure that would do what I need, let alone how it would 
perform/scale.

Any thoughts, suggestions, comments welcome.

Re: Problem running Tomcat on Windows 64-Bit Edition

[Bill Barker]

There is a srvbatch in commons-daemon (I'm too lazy to look if there is a 
binary released for it :) that will allow you run the batch files as a 
service.

You can also grab the source from commons-daemon and compile a 64bit version 
yourself (only the MSDK is needed, but you need to create your own 
makefiles).

I've done both, and they both work well (but only the second one lets you 
have the nice configuration GUI :).

I am trying to run Tomcat 5.5.9 as a service on Windows Server 2003

 - 64-bit JDK and Tomcat 5.5 using startup.bat

However, I can't run 64-bit JDK and Tomcat 5.5 as a service because it
runs tomcat5.exe, which is 32-bit app (32-bit apps cannot reference

Is there a 64-bit binary for tomcat5.exe, is it possible for me to build

Tomcat to run as a service using only the .bat files?  Thanks for any

Note, you will always get a stacktrace if Tomcat can't compile a JSP - I 
believe this is appropriate as this is a "developer" error rather than a 
"runtime" error.

No, it has compiled OK or else you'd get the same kind of message as you 
did previously.

I suspect the reason you get a blank page is that for reason's I've never 
been able to discover, SQL Exceptions are nested and the last error (the 
one shown on your error page) is always empty :-(

to see the true error(s), you have to write some code that works its way 
back through the nested SQL Exceptions, printing out the message for each 
as you go.

Something like the following (untested) in your error.jsp should do the trick:

<%
  if (exception == null) {
%>
A null exception was encountered
<%
  } else {
if (exception instanceof SQLException) {
  Exception e = exception;
  while (e != null) {
%>
Error Code: <%=e.getErrorCode()%>
Message: <%=e.getMessage()%>
<%
e = e.getNextException();
  }
} else {
  // non-sql error handling here...
}
  }

RE: Error 500 messages

[Adile Abbadi]

Hi Anoop thanx for your help - first in regards to the file that the log is
writing to I'm referring to a log file I created for my context in the XML
supporting that context using the FileLogger (similar to as you have below).

Now I did a little more experimenting and discovered something interesting -
as I said I can get an exception to be thrown to the page in a simple JSP
file (I made it do a null pointer for example) and I can get it do pretty
any other exception as well. Now what I did is I took one my more
complicated JSP pages, made a copy and made a few changes to force some
exceptions - now here is the weird thing - some exceptions are thrown to the
screen and some are not.

For example I had a ResultSet DB object and I made a syntax error and I got
an Error 500 screen to come up as follows (note I took out the extra stuff
to shorten the email)

org.apache.jasper.JasperException: Unable to compile class for JSP

/var/lib/tomcat4/work/Standalone/localhost/podims/mod_pat_test_jsp.java:118:
')' expected
while(SQLR.next() {

I also got it do a null pointer exception:

org.apache.jasper.JasperException

Root Cause
java.lang.NullPointerException

However I tried to get it to do a syntax error in the query - and I end up
with a blank page. The catalina log shows nothing, but my context log shows
the following (clown is the word I used to screw up the query)

javax.servlet.ServletException: ERROR:  syntax error at or near "CLOWN" at
character 260

--Root Cause--
java.sql.SQLException: ERROR:  syntax error at or near "CLOWN" at character
260

Its almost as it the page refuses to compile with this error.

Any ideas - is it a configuration thing?

Thanx

It might be easier than you think to output the error right onto the
page itself.

But would it help if you see the errors (+ other things) on the tomcat
console?? It will certainly help in your debugging.

To do that edit the server.xml in the conf directory and remove lines
similar to this:

  

The only problem I have seen when I do this is that a lot of
information prints out on to the console and makes it cluttered - but
my hope is that when you get an error/exception you will be able to
notice it in the console amidst all the other debugging info. Also
ensure that the debug has the value 0 in the host tag. This will
reduce the amount of debugging info.

Another point I wish to make is that when there is an error tomcat
just writes one file I am not sure which files you mention that
tomcat writes

The easiest thing I do and it works too is that - everything is
outputted into my one output file catalina.out and I use "tail -f
catalina.out" to see what is going on - of course this works only on
*nix servers (pity windows!!)...

As far as I am aware, Tomcat currently has to be restarted if anything that is 
configured in server.xml is changed, whether by editing server.xml directly 
or by changing it using the Admin console.

I have previously asked a question on this list about automated 
management of server.xml (eg via an api or whatever) but have not

responding to user requests from the browser. Once the application
enters this state, even if a new browser window is launched, none of the

You're going to have to be more specific than "it does not seem to work."
What did it do, and what did you think would happen?

I'm not sure if you're expecting Tomcat to "do something" when you start it
in debug mode.  It doesn't.  It acts normally until you connect to it with
the debugger you've chosen to use.  (Which one is that?)

I'm also unsure of the difference between 'run' and 'start'.  If you just
type 'catalina.bat' with no parameters, it prints out a usage statement that
lists 'jpda start' but not 'run jpda'.  Since it lists both 'run -security'
and 'start -security' separately I have to wonder if  'run jpda' is even a
valid option.

Re: What commands to run in the Tomcat Debug Mode on Linux

[Jyothi Palvai]

But I am on a linux box and I am unable to get it to start by using the socket. 
I set the socket to 8000 but it does not seem to work, JPDA_ADDRESS=8000 and 
JPDA_TRANSPORT=dt_socket  is already set in catalina.sh, so I just run using 
catalina run jpda. And when I run tomcat it starts and after that nothing 
happens.

You appear to be asking how to use your debugger, which we can't answer
unless you tell us what you're using.

I use JSwat with the Tomcat, Struts and Commons source code available. All
I do is start Tomcat with 'catalina.bat jpda start'. On Windows, it
defaults to shared memory, and I see the following in the console:
Listening for transport dt_shmem at address: jdbconn

(IIRC, on Linux it defaults to the other option, involving a socket.) There
is some info here:

Error 500 messages

[Adile Abbadi]

Hi 
all,
 
I've got a very 
simple question to ask and I'm sure someone out there can help me. Ok I just 
migrated from Tomcat 3 to Tomcat 4 and everything is working great except one 
little thing. But a little background before I go on.
 
Apache/Tomcat4 
configuration - using libapache-mod_jk as the connector.
Running on 
Linux
JDK1.4
 
My app is built in 
JSP with JavaBeans in the background. Most of JSP's are built as 
follows
 
Container JSP 
file
--jsp includes 
doing different thing like load session variables or nav menus, 
etc.
 
Alright so here is 
the issue - in Tomcat 3 - whenever an error occurred such as a null pointer, or 
other exception - the error would output right to the JSP page itself and I 
could see it on the screen.
 
Now in Tomcat 4 it 
outputs the error to the log. This is all fine and dandy but it makes it hell to 
try and fix issues having to sift through log files to figure out what the 
problem is. 
 
Now I have tried 
to build a simple test.jsp file and force it to through an exception and that 
works fine (gives me the standard apache/tomcat error 500 screen) - but for some 
reason in the more complicated jsp pages - I can't get the exception to come to 
the screen.
 
So any 
ideas??
 
Thanx
 
Adile

Dynamic server configuration...

[Rodrigo Spievak Cavalcanti]

Hi folks,

   Is there any way to change tomcat engine configuration at runtime, 
without restarting the entire engine ? Some kind of dynamic engine 
configuration, being able to change hosts, add hosts, and changing host 
configurations ?


  Thanks.

RE: tomcat 4.x classpath

[Bergthorson, Jason]

I want to add a directory that I have in my j2sdk\jre\lib\ext that I am
using for development on that server.  
I don't want to have to copy that folder over to tomcat/common/classes
(for example), and have 2 copies of my code on the same system.  I would
rather add my j2sdk\jre\lib\ext\X to tomcat's classpath, or just have
tomcat read my system classpath and get it from there.
But by default tomcat does not use your system classpath, and I can't
figure out how to either add the system classpath to its classpath or to
add directories to it.  It would read jar files from my lib/ext I
believe, but because this code is in development it is not yet in a jar
file.

Ouch! Thats a LOT of threads - I can't believe your box still performs

The number of threads really depends on your application. I have max 
threads set to 750, or our 32bit 2.6 Linux systems. Our thread count 
normally doesn't go over 200. When the servers need to wait for the

The number of threads really depends on your application. I have max 
threads set to 750, or our 32bit 2.6 Linux systems. Our thread count 
normally doesn't go over 200. When the servers need to wait for the

On either linux kernel, you probably want to increase your maximum

Tomcat user account(s).  16K nofile as default works great for me.


How much more memory you need really depends on your application.  500 
threads isn't that much memory overhead, but if each thread goes off 
and creates a bunch of objects while it's working you'll need to 
assure heapspace is available accordingly.  The short answer is: try 
it out, play with it.  500 threads isn't a whole lot.

Subject: forwarding (and adding to) a request to another server

Hi,

I have a secure webapp (main portal) in Tomcat that calls webservices 
for authentication. There are other *existing* apps on different 
servers. All users log in to all apps through my app (single sign on). 
When a user clicks a link in my app that is to go to another secure app, 
I need to call a web service to get authentication info for that 
particular app. Then, POST the authentication info to the other server 
and have the requested page show in the browser.

Is there some way to:

1. get the request in a Filter
2. call the webservice and get auth info
3. redirect/forward/open-a-url-conn to POST the auth info as form data 
to another app
4. finally, have the other app's page show in the user's browser

?

Anybody done anything like this? Any ideas? Is it possible?

I could do this with JavaScript by building the form for each page that 
have these secure link types. But, it complicates things a great deal 
because I would need to call the webservice and put the auth info 
(encrypted strings) on the page even though the user may never click the 
link.

any ideas,
-Rob

Re: Max thread/session timeouts

just a few facts on threads in Tomcat:

  . you'll need (Xss*max_threads)+Xmx+x memory in your box, where x is
the memory needed by the basic JVM tasks besides the thread space
(say, 100MB).

  . on ia32/Windows, you can only assign 1.6GB (Xmx-)memory to a single
JVM. A value above it will break the 2GB barrier and will not run.

  . you need to find the balance between max_threads and Xmx. A lower Xmx
gives you a higher max_threads and vice versa.

  . Tomcat on Windows doesn't scale well. Use multiple Tomcat instances
on one box if you have a large box. In my setup, I run 4 Tomcats on a
2xXeon system with 4GB memory. Each Tomcat gets 1000 threads and
512MB. This is _much_ faster than a single Tomcat with all
memory and 4000 threads.

  . Windows 2003 Server, at least the Standard Edition has major
limitations in both TCP connections and memory. There are some
workarounds using esoteric registry keys, but none of them works
well. Windows is a crippled desktop os that wants to be on the
server. If you want really high performance on large boxes, use
Linux (Kernel 2.6!). You even get a better administration
interface. Hate this inefficient administration-by-clicking ;-)

Problem running Tomcat on Windows 64-Bit Edition

[Spors, Jeffrey R]

I am trying to run Tomcat 5.5.9 as a service on Windows Server 2003
64-Bit Edition.  

The following scenarios work fine:
 - 32-bit JDK and Tomcat 5.5 running as a service and using startup.bat
 - 64-bit JDK and Tomcat 5.5 using startup.bat

However, I can't run 64-bit JDK and Tomcat 5.5 as a service because it
runs tomcat5.exe, which is 32-bit app (32-bit apps cannot reference
64-bit apps and vice versa on Windows 64).

Is there a 64-bit binary for tomcat5.exe, is it possible for me to build
tomcat5.exe as a 64-bit app from source, or is there a way of getting
Tomcat to run as a service using only the .bat files?  Thanks for any
help.

Re: Max thread/session timeouts

[J. Ryan Earl]

As a reference, in conf/server.xml I set my thread limit to 1 max 
threads, 1000 max idle threads, and 100 on startup.  I've seen my as 
many as 7K threads busy within my application.  This is on a 32bit 2.6 
Linux kernel with 2GB of RAM (-Xmx1500m).  On the 2.4 kernel I found 
practical limitations in how many "threads" the kernel could multiplex 
between, saw frequent system hangs under high load where the whole 
server would become unusable.


On either linux kernel, you probably want to increase your maximum 
number of file descriptors in /etc/security/limits.conf for your Tomcat 
user account(s).  16K nofile as default works great for me.


How much more memory you need really depends on your application.  500 
threads isn't that much memory overhead, but if each thread goes off and 
creates a bunch of objects while it's working you'll need to assure 
heapspace is available accordingly.  The short answer is: try it out, 
play with it.  500 threads isn't a whole lot.

Re: Apache2+jk+tomcat5.028+uri utf-8 [NOT] SOLVED

[Chris Brown]

Hello, Sorry for not replying to the thread referenced in my subject (See July 
1st, 2005), I'm new to the list and didn't have the email to reply to. 

I am having the same trouble that Paul and Steve encountered. (Error connecting 
to tomcat from mod_jk). Like Steve I have two similarly configured machines, 
one works, one doesn't. I can provide configuration files and more detailed 
logs but the errors I get are similar. Maybe I can peek someone's interest or 
jog a memory by proviging more detail.

I'm running two identically configured Fedora Core 4 boxes. The one that works 
is running on a Pentium II 450mhz running (FC4 i386), the one that doesn't work 
is running on a Xeon 2.8ghz (FC4 x86_64).

I've compiled mod_jk v1.2.14.1 from source on each box configured everything 
with simple settings from the tomcat connector HOWTOs. I'm running apache 
2.0.54-10. I also tried downloading a precompiled binary 
(jakarta-tomcat-connectors-jk-1.2.10-linux-sles9-x86_64-prefork.so) but didn't 
have any better results.

I tried pointing the working box's workers.properties file to the other boxes 
tomcat to confirm tomcat was in fact listening on port 8009. That worked.

I turned off my firewall to ensure that wasn't the issue. below is the log from 
mod_jk. I can provide one with debug message but thought I'd start with the 
shorter version.

Thanks for any help on this matter, I'm stumped.

Re: Ports 8005 8009 8080 in default Tomcat 4.x installation.

[Darryl L. Miles]

127.0.0.1:8005 : Shutdown port, I've not seen this working in TC in a 
while.  You are meant to be able to connect and send the shutdown 
password with EOL and it instructs TC to shutdown gracefully.  Other 
method of doing the same include installing the TC admin webapp and 
doing the same thing from the frontend.


127.0.0.1:8009 AJP/1.3 (Apache J Protocol) Connector port.  This is used 
to connect Tomcat to another webserver, for example with Apache Httpd 
you would install mod_jk in the httpd and it would connect to TC on this 
port.  There are also other connectors for IIS that use this common wire 
protocol to comunicate.  I believe this wraps the HTTP request response 
with other control information in a more machine readable format than 
making TC re-parse the entire HTTP request and also can convery SSL 
security info if mod_ssl is in use.


publicIP:8080 HTTP Webserver.  This is a direct HTTP server 
implementation Coyote inside TC, this allows TC to act as a standalone 
webserver without the need for Apache/IIS.

Yes it should (and does for me) work.


Is there anything else I can try?


1. Try accessing Tomcat directly to see if mod_jk is causing problems.
2. Try 4.1.31 - it has a bunch of bug fixes that might (I haven't 
checked the release note for details) help
3. Try the following simple test JSP and once this works, see how your 
app is different.

Request parameter data not being recognised as UTF-8

[Tim Koop]

Hi everyone.

___ The Problem ___

I have a web page form that is expecting UTF-8 data, but when my code 
gets the data, the getParameter() methods don't return the right thing.  
I have to run this code to get the right thing:


String value = new 
String(request.getParameter("fieldName").getBytes("ISO-8859-1"), "UTF-8");


Naturally I don't want to run this code every time I want a simple 
parameter.  There must be a setting somewhere.


The page itself displays fine; the form data that it gives me is not 
being interpretted as UTF-8.



___ What I have tried ___

I have searched the web and have found these possible solutions, but I 
can't get them to work for me.  I have tried all the following things:


In server.xml, I have added these lines to each Connector:
 URIEncoding="UTF-8"  useBodyEncodingForURI="false"
 (I have also tried useBodyEncodingForURI="true")

I have added this text to JAVA_OPTS (in my rc.d init script) and have 
confirmed that these are indeed Java system properties

-Djavax.servlet.request.encoding=UTF-8 -Dfile.encoding=UTF-8

I have tried calling request.setCharacterEncoding("UTF-8") in my code.  
I've even made it the first line of the jsp page.  No luck.


I have restarted Tomcat many times.

I even have the environment variable LANG set to "en_GB.UTF-8"

I have <%@ page contentType="text/html; charset=UTF-8"  
pageEncoding="UTF-8" %> in my jsp page.
I have  in my jsp page.


___ My questions ___

Should this actually work and I'm just doing something wrong?

Is there anything else I can try?


___ Technical details ___

I'm using Tomcat 4.1.30, Apache httpd 1.?, mod_jk, Sun JVM 1.4.2, Linux 
Fedora Core 2.4.22


A part of my server.xml file looks like this:
   
 
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"

  URIEncoding="UTF-8"
  useBodyEncodingForURI="false" />



Thanks for any ideas.  I've tried everything I can think of.

You appear to be asking how to use your debugger, which we can't answer
unless you tell us what you're using.

I use JSwat with the Tomcat, Struts and Commons source code available.  All
I do is start Tomcat with 'catalina.bat jpda start'.  On Windows, it
defaults to shared memory, and I see the following in the console:
   Listening for transport dt_shmem at address: jdbconn

(IIRC, on Linux it defaults to the other option, involving a socket.)  There
is some info here:

Re: Ports 8005 8009 8080 in default Tomcat 4.x installation.

[David Smith]

8005 = default shutdown port.  I believe it used to be the default ajp12
port.  This is bound specifically to 127.0.0.1 and cannot be accessed
from any other system.
8009 = default ajp13 connector port.  Can be disabled if you aren't
using mod_jk to connect with Apache or IIS.
8080 = default http protocol port.  Change this to 80 if you are using
Tomcat with out Apache or IIS in production.

I take it you know the 150 is the default limt in the config/server.xml 
and this can be upped towards you operating system platform maximum.


A ball park of your applications memory needs @150 threads is better 
chcked by simply looking at the paged in size while under that load (the 
RSS size in "ps uaxw" under Unix).  You can't expect us to guess exactly 
how much more memory you need from the information you've given, I mean 
you've not told us if you already have 8Gb of RAM installed or just 32Mb 
for us to at least take a guess at the answer.


Maybe the Java VM -Xss is a useful option to look at, but I think 
providing you are not hitting your upper limit on a single process 
memory usage (into the 3/4Gb realm on 32bit) for a high number of 
threads then it will make little difference.  As I believe stack space 
just like other application memory is paged in as its used and reducing 
the stack space to a lower limit than your application need will just 
make it crash.

Start here first:

Re: Problem with refreshing JSP

[Travis Stevens]

The other thing to note about reloading JSPs is that tomcat 5.5 seems 
to copy ones web context directory into its own webapps directory.  
Any changes to the original JSPs will not show up unless you 
physically copy the JSP from the original directory to the webapps 
directory.



I haven't observed this behavior with my Tomcat 5.5.
Maybe you have set antiResourceLocking="true" or something like this. 
In this case I think tomcat will copy all the files.


I double checked and antiResourceLocking is false.  Is there some other 
configuration property somewhere that would indicate that the webapp is 
to be copied?  I use the 5.5.9 tomcat for Linux pretty much right out of 
the box.

[Jasper/Orion] compile JSP servlets

[Romain Thouvenin]

I'm trying to write an ant task to pre-compile JSP pages, but I have the 
following problem.


Here is a piece of page :
# 
(itlBean.getIdy() returns a Long.)

Then I try to transform the JSP page into a servlet with the jasper 
task, which gives the following java code :

#  _jspx_th_form_input_0.setParent(null);
#  _jspx_th_form_input_0.setType("hidden");
#  _jspx_th_form_input_0.setName("idy");
#  _jspx_th_form_input_0.setValue( itlBean.getIdy() );

But the value field in the tag handler is a String and so the setter is 
void setValue(String value), therefore javac refuses to compile the 
corresponding servlet.
Unlike jasper, Orion (the server I'm using) generate the following java 
code for the same page :

#__tag1.setParent(null);
#__tag1.setName("idy");
#__tag1.setType("hidden");
#__tag1.setValue(com.orionserver.util.ObjectUtils.toString( 
itlBean.getIdy() ));


Great ! Orion recognized the problem and convert the Long to a String.
And now my question :
Is jasper able to do that ? How ?
If not, does this way of proceeding conforms exactly to JSP spec. ?
Can my problem be solved ?

Thanks for your help.

Where to beging with secure mail

[Brian McGovern]

Can anyone tell me how to get my app, which uses java mail to get a secure 
session with my smtp resource as defined in my context file.



mail.smtp.host 
192.168.100.24
mail.smtp.socketFactory.class 
javax.net.ssl.SSLSocketFactory
mail.smtp.socketFactory.fallback 
false
mail.smtp.socketFactory.port 
465


I get an error that my smtp is not communicating via SSL.  Its an IIS box, but 
ill also need to do this on linux running sendmail in the near future.  What I 
dont understand is the key generation process and how to configure ssl on the 
mail side.  

Any help or ref docs would be a great help.

apache2.0.54 + 2 tomcat 5.0.28 + jk 1.2.14

[Hallvard Lid]

I've got this setup working on my testserver(win2003), the apache
answers on port 80 and talks to the two tomcats through the jk-connector
on some other ports. The problem is that the tomcat servers have some
bad code in them and from time to time they just hang for a while eating
cpu. Earlier we countered this bad programming with a cheap hack that
timed the loading of an index.jsp and killed the prosess. Now on the
other hand it is hard to tell which server that is causing trouble
because of the transparancy in the setup.

The connector(jk) has some advanced options that probably are meant for
this kind of situation, but I can't seem to find any way to actually do
something(other than ignore the lost server in the loadbalancer). Is
there any way to channel a request through the apache server and onto a
specific tomcat? Or any other aproach to make apache(or windows) restart
the tomcat that goes haywire.

The only real good solution is ofcourse to find the source of the
problem in the java-code on the tomcats, but that ofcourse takes time
and money...

Re: can't start tomcat as user

[David Smith]

This problem can be caused by the port <= 1024 problem under unix/linux. 
If so, take a look at the commons-daemon project on the jakarta site.


Also be sure your config, log, webapp (optional), work, and temp 
directories are owned by the tomcat user. They should be writeable by 
tomcat at least and I've seen cases in my system where ownership was 
necessary. Don't ask me why -- I have yet to explain it myself.


LastIy, check catalina.out for errors. The logs are invaluable in 
finding problems.

On Linux, only root can open ports below 1024 (included). You must
compile the jsvc program and setup a tomcat user and it will start
tomcat as root and then change the effective user before receiving
requests. I hope this help. (jsvc is in the bin folder, i think is

tomcat 5.5.9 jdk 1.5 howto

[Werner Punz]

The howto on the website is slightly wrong
here is the exact howto

first of all remove all jikes related jars from the tomcat lib dir,
second add tools.jar from the jdk to the tomcat classpath
third add ant.jar from an ant installation to the classpath
fourth replace the servlet entry from the conf/web.xml
with following:

 

jsp
org.apache.jasper.servlet.JspServlet

fork
false


xpoweredBy
false


 compiler
 javac1.5


 compilerSourceVM
 1.5


compilerTargetVM
1.5  


3


and now startup tomcat with a working jdk 1.5 and pages should compile

Re: binary streaming / content-type problem with mod_jk ?

[Jérôme Chauvin]

Thanks for your answer Henri :)
I agree with you, finally I don't think the problem comes from mod_jk
It may be Apache (using mod_jk and Tomcat) like described by Stuart 
Hynd in his post on this page : http://www.junlu.com/msg/107218.html


Or, perhaps, QuickTime 6 which is more "weaker" than QT7 which doesn't 
care about the thing which makes the problem (and I would like to know 
where this thing comes from).


But the incredible thing is that, using this : 
http://localhost:8080/my_test/BinaryStreamingit works perfectly on 
QT6  (without the 8080 port, the latence problem appears -> QT6 or the 
servlet or Apache, is waiting for the video file entirely created 
before starting to play it)...



Any other suggestions or opinions about this mystery ? :)

Hi all !

I've developed a servlet ("BinaryStreaming" based on
"StreamingContent" by Raj Behera) which does a binary stream of a 
mpeg

video file which is created progressively (by another
servlet/software/Unix command/... not important ) and finally read 
and

played by Quicktime.
I use Apache and Tomcat so I've installed mod_jk

All work well (-> MacOS and Windows) but... :
If I go on http://localhost:8080/my_test/BinaryStreaming it
works well with QuickTime 7 and QuickTime 6 (6, 6.5, 6.5.2, ...).

I have mod_jk so I can go on
http://localhost/my_test/BinaryStreaming   and here it still 
works

well with QT7.
But QT6 seems to wait that the video file is entirely created to 
start

the viewing instead of starting to play the movie as soon as there is
data in it, progressively.
-> like it does with QT7 and QT6 with :8080  OR  when I use QT7
without :8080.

I think it's due to mod_jk but I've no idea to make it work


I've found that another person had a similar problem, but no answer
was given :
http://www.junlu.com/msg/107218.html

This message was posted in 09/2004 and it seems that Apache causes
problems with pre-defined MIME-Types.

That is operating system dependent. On linux you will have to write a script

Tomcat stops responding

[Manfred Steurer]

We have an app running productive for ~1 year without noticeable errors

(Tomcat 4.1.24, Java 1.4.1_03, Postgres 7.3 on RedHat 9).
But recently tomcat stops processing requests now and then.
- Tomcat is running
- No errors in the logfiles
- Due to RequestDumperValve Tomcat does not receive any requests when locked
- Other non-Tomcat java-apps on this server (using the same db) don't 
encounter any problems


After restarting Tomcat everything is fine.

Any suggestions will be appreciated.
