RE: Tomcat threading questions
Bill:
Eventually the browser will drop the connection, and then if
the Servlet
tries to write anything, then an IOException will be thrown. However
allowing the following code on your server will DoS:
while(true) {
Thread.Sleep(1000);
}
This is precisely my question: Is there a way to set a
timeout on a thread and kill it if it takes that amount of time?
The thread allocation is pretty similar to Apache/httpd.
The Apache server source code has a hard thread limit defined
in the source code. Does Tomcat?
Thanks,
Neil

Tomcat threading questions
Hello: I have a couple of questions about the way Tomcat uses threads: 1. If a thread does an infinite loop or other operation that would cause it to wait forever, will Tomcat kill it? If not, is there a way to do that? If so, how would we control the timeout? 2. Is there a hard limit on the number of threads like in Apache or does it allocate up to maxProcessors no matter how large it may be?

Neil, Have not talked to you in a while, and I have not tried this particular Linux configuration, but I can tell you that it is not unusual to have to either copy files from one directory to another or set up symbolic links to make the ant build/make work. My primary target platform for Tomcat is (Red Hat) Linux followed distantly by Solaris (SPARC) 8.0. I seem to recall having to do Symlinks in both cases. I hope this helps. If not, I will consider building a RedHat 9.0 box to check it out.

RE: Tag Handler pool eating up Memory (and enablePooling is set to false)
Chris: Yeah, it's possible (and probable) that the TagHandlerPool maintains a reference back to the ServletContext in which it lives. That might kew your results. I'm sure that the TagHandlerPool isn't actually taking up that much memory. This is strange. When I created a heap dump from my server just now, it does not have any instances of TagHandlerPool in the heap dump. That is what I expected before, but I still had them in my last dump. Do you have any of your own tag libraries, or are you using only 3rd-party taglibs? If you are using your own, check to see if you are holding on to references or something like (anything like shared objects between tags -- that kind of thing). We are not using any 3rd party tag libraries. We are using our our tag library. I will look into that. If you have a profiler handy (something more robust that the heap dumper), check to see how many instances of various types there are. For example, if you are using org.foo.bar.taglib, then filter the object list by org.foo.bar.taglib and take a look at how many instances there are. If you find that there are thousands of references to tag handlers, then something is probably wrong with Tomcat. Otherwise, several hundred references doesn't sound horrible. It's possible that they haven't been GC'd yet. Doing a quick grep on my summary results from the new heap dump, I get this result: 60256,1076,com/slsideas/pagegen/tags/SetPropertyTag 31296,652,com/slsideas/pagegen/tags/ValueTag 23088,481,com/slsideas/pagegen/tags/ProcessTag 13008,271,com/slsideas/pagegen/tags/IfNotNullTag 9888,206,com/slsideas/pagegen/tags/IfNullTag 9600,200,com/slsideas/pagegen/tags/IfEqTag 5616,117,com/slsideas/pagegen/tags/IfExistTag 4992,104,com/slsideas/pagegen/tags/IfNotEqTag 3216,67,com/slsideas/pagegen/tags/IncludeTag 3136,49,com/slsideas/pagegen/tags/LoopTag 960,20,com/slsideas/pagegen/tags/IfNotExistTag 608,2,class com/slsideas/pagegen/tags/ValueTag 608,2,class com/slsideas/pagegen/tags/SetPropertyTag$Converter 608,2,class com/slsideas/pagegen/tags/SetPropertyTag 608,2,class com/slsideas/pagegen/tags/ProcessTag 608,2,class com/slsideas/pagegen/tags/IncludeTag 608,2,class com/slsideas/pagegen/tags/IfNotExistTag 608,2,class com/slsideas/pagegen/tags/IfExistTag 608,2,class com/slsideas/pagegen/tags/BaseTag 304,1,class com/slsideas/pagegen/tags/LoopTag 304,1,class com/slsideas/pagegen/tags/IfNullTag 304,1,class com/slsideas/pagegen/tags/IfNotNullTag 304,1,class com/slsideas/pagegen/tags/IfNotEqTag 304,1,class com/slsideas/pagegen/tags/IfLoopTag 304,1,class com/slsideas/pagegen/tags/IfGreaterThanTag 304,1,class com/slsideas/pagegen/tags/IfGreaterOrEqTag 304,1,class com/slsideas/pagegen/tags/IfEqTag 304,1,class com/slsideas/pagegen/tags/EscapeValueTag 56,1,com/slsideas/pagegen/tags/IfLoopTag The first column is the total bytes held by the instance inself (not including references), the second column is the number of instances that were present in the heap dump, and the last column is the type of the object. I find it very hard to believe that we have over 2500 active instances of our tags. This seems to imply they are not being garbage collected. I also noticed that you are using JDK 1.4.1. I've heard that this version (it might only be the Sun distro -- can someone confirm?) has an implementation of StringBuffer that has a terrible memory leak. You might want to consider upgrading to 1.4.2 if that's possible. I ran some code to count all of the instances of java/lang/StringBuffer and the total bytes they hold both in themselves and their references. I got 2,925,512 bytes in 15,914 instances of java/lang/StringBuffer. The heap dump shows 174,740,832 total bytes used in 892,512 total instances. I don't belive the StringBuffer is the cause of my problems. Thanks, Neil. -- Neil Aggarwal, JAMM Consulting, (972)612-6056, www.JAMMConsulting.com FREE!

Tag Handler pool eating up Memory (and enablePooling is set to false)
Hello: We have several tomcat servers running an application. The servers slow down after a few hours of uptime. Looking at the memory usage on the servers, we noticed that the servers seem to be accumulating memory and finally they slow down when the memory utilization becomes high. We are using the IBM JDK 1.4.1 SR1 with Tomcat 4.1.24 on RedHat 9. Using the heapdump utility from the IBM JDK, I generated a heap dump from one of the servers after it had been up for a while. From that output, I see these pieces of infromation: There were a total of 509,235 objects in memory taking up 67,992,688 bytes. There were 436 instances of org/apache/jasper/runtime/TagHandlerPool. Tracing all of the references from these TagHandlerPool object, they reference a total of 65,010,600 bytes. This means that almost 97% of the memory usage of Tomcat is being referenced from the TagHandlerPool objects. I have enablePooling set to false in the Tomcat's web.xml in the conf directory. It seems that the enablePooling setting is not preventing Tomcat from pooling the tag handlers and they are referencing a lot of memory. Does that setting work in Tomcat 4.1.24? Is there any other reason why Tomcat would behave this way? Thanks, Neil -- Neil Aggarwal, JAMM Consulting, (972)612-6056, www.JAMMConsulting.com FREE!

Re: SESSION REPLICATION: RedHat 9 and Sun JDK 1.4.2 do not like to play
Euan: FYI regarding using IBM JDK on RH9 - we also experienced core dumps and had to roll back to SUN.. The RH9 release notes state that the IBM JDK has 'problems' with RH9 'NPTL' which is on by default but can easily be *turned off*.. What version of the IBM JDK have you been using? According to this page: http://www-106.ibm.com/developerworks/java/jdk/other/portingplans.html They state: On Linux for Intel 32-bit platforms, the current 1.4.1 Java SDK works with the new NPTL threading library when run on the Red Hat 9 distribution.

Performance problem?
Hello:
We have noticed that in our app, on occasion, a request takes an
inordinately long time to execute even though it is performing a
simple task.
I added some tracing to the org.apache.jasper.servlet.JspServletWrapper
class and get this output immediately before calling service
on the servlet created from my jsp file:
10/10/2003 8:52:08.635 AM [Thread-188] Calling service on
org.apache.jsp.index_jsp
My code is in the call to the service() method of the servlet after
checking
that Tomcat is not running a SingleThreadModel:
if (theServlet instanceof SingleThreadModel) {
// sync on the wrapper so that the freshness
// of the page is determined right before servicing
synchronized (this) {
theServlet.service(request, response);
}
} else {
com.slsideas.pagegen.servlets.BaseControllerServlet.addNote(request,
Calling service on +theServlet.getClass().getName() );
theServlet.service(request, response);
}
My next line of output from the same thread is in my jsp file at the
very top. It
gave me:
10/10/2003 8:53:49.193 AM [Thread-188] At top of index.jsp
So, you can see that it took over a minute and a half to get from the
invocation of the
service method on my jsp servlet to the actual execution of it.
This seems strange to me, since this is just a method invocation.
I don't believe this is caused by compilation of the jsp file since I
have development
set to false in tomcat's config file and this code is past that point in
the JspServlet
class.
I don't believe this is garbage collection related since I have the
verbose garbage
collection flags turned on and I see that the GC for 100 seconds before
and after
this event look like this:
6467.31: [Full GC 285948K-236784K(460072K), 1.7318340 secs]
6497.1: [GC 287631K-259103K(460072K), 0.0225250 secs]
[My output occurred here]
6497.84: [GC 287775K-259175K(460072K), 0.0198420 secs]
6529.71: [Full GC 382024K-259185K(460072K), 0.7856030 secs]
The garbage collector is not taking very long to run.
Does anyone have any insights to why this is taking so long?
Thanks,
Neil.

Re: Slow serving requests issue
Alex: We have been trying to diagnose a similar problem that we are experiencing on our servers. All of our requests come into our controller servlet. The servlet then forwards the request via a RequestDispatcher to a jsp page for display. On occasion (at least once a day), one of these requests take about 4 minutes to go from the forward call to the jsp. We do not currently have an explanation for it, but as trying to track it down thru the Tomcat source code with Filip Hanik's help. We are using Session Replication across our 4 web servers.

Request dispatcher fails on encoded url when used in post (Bug?)
Hello:
I am getting a failure in my code when using a request dispatcher
to forward the request to an encoded url from a post operation.
To see it in action, do the following:
1. Turn off cookies on your browser
2. Visit http://dev.jammconsulting.com/gen?_template=/index.jsp
3. Hit the Test button.
You will get this error:
HTTP Status 404 - /gen;jsessionid=BF99242CF6F9E32C44D50EACE5576AD5
type Status report
message /gen;jsessionid=BF99242CF6F9E32C44D50EACE5576AD5
description The requested resource
(/gen;jsessionid=BF99242CF6F9E32C44D50EACE5576AD5) is not available.
Apache Tomcat/4.1.27
Now, turn on cookies and try it again. You will get a page that states:
This is compose.jsp
Session id is BFBC13C89DD4B3F5A98EF8E53F0D6A45
I thought that Tomcat is supposed to act the same with cookies on or off
when I use encodeURL on all of my urls.
Here is the code behind this sample:
In httpd.conf, ask apache to map all urls that begin with /gen into
tomcat:
LocationMatch /gen
JkUriSet worker ajp13:localhost:8009
/LocationMatch
In tomcat server.xml, I told tomcat that the root context uses
my app:
Context path= docBase=email debug=0/
In my app's web.xml, told it to map all request for /gen to
my test servlet:
?xml version=1.0 encoding=ISO-8859-1?
!DOCTYPE web-app

public class TestServlet extends HttpServlet {
private void process(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
getServletContext().getRequestDispatcher(request.getParameter(_template

}

response)
throws ServletException, IOException {
process(request,response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
process(request,response);
}
}
Here is the index.jsp template, which posts to the massCompose template:
P
Session id is %= session.getId() %
P
form name=groupList method=post action=%=
response.encodeUrl(/gen) %
input type=hidden name=_template value=/massCompose.jsp
input type=submit value=test
/form
Here is the massCompose template which forwards to the compose template:
%
RequestDispatcher rdispatch =
request.getRequestDispatcher(response.encodeURL(/gen?_template=/compose
.jsptype=normal));
rdispatch.forward(request, response);
%
Here is the compose template which just displays a message:
HTML
BODY
This is compose.jsp
P
Session id is %= session.getId() %
P
/BODY
/HTML
Any ideas why this is occurring?
Thanks,
Neil

RE: Request dispatcher fails on encoded url when used in post (Bug?)
Filip:
There is no space in the url, it is an underscore.
As far as the last slash, why would it work correctly with cookies
on and not with cookies off?
It should work the same with and without cookies. If it did not work
in both cases, that would make sense to me.

Has anyone gotten Castor to work using JNDI and
the JBCP pooling mechanism?
My platform is Tomcat 4.0.6, Apache 2.0.43, and

Hi Neil, cookies are bound to the server name, so you can't use cookies (the default method with Tomcat) to track sessions. If you are not doing form-based realm authentication, you can use URL rewriting to track the session by setting: cookies=false for the contexts you are serving (you could also do it for the default context). I think this is what you are asking. Thanks, Adi On Sat, Apr 13, 2002 at 11:48:40PM -0500, Neil Aggarwal wrote: Hello: I am using Apache 1.3 and Tomcat 4.0.3.

RE: Apache + Tomcat Virtual Host not loading web.xml
Larry: The JkMount is in the apache httpd.conf file, but the web.xml should be read by tomcat when it starts up. Apache is not even in the picture yet. I think the problem is that tomcat is either: 1. Not processing the web.xml. 2. Not finding the setup servlet. I dont think this has anything to do with the servlet mappings of apache. Thanks, Neil. -- Neil Aggarwal JAMM Consulting, Inc.(972) 612-6056, http://www.JAMMConsulting.com Custom Internet DevelopmentWebsites, Ecommerce, Java, databases -Original Message- From: Larry Isaacs [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 06, 2001 7:48 AM To: '[EMAIL PROTECTED]' Subject: RE: Apache + Tomcat Virtual Host not loading web.xml I don't think you have a servlet mapping until you add a servlet-mapping entry to your web.xml. I could be wrong, but I don't believe the Servlet spec guarantees you can access the servlet by name with just a servlet-name. That nitpick aside, I assume you are using Tomcat 3.2.x. Neither mod_jk or mod_jserv pass web.xml information to Apache. All Apache knows about Tomcat's contexts is what it gets from the config file(s). You will need to manually add the servlet mappings you need, JkMount /setup ajp13 in your case. Tomcat 3.3 tries to support this a little better by including servlet mappings in the auto-generated config file. However, this is not the default behavior for generating the config file. Instead, the default is to map all requests related to a Tomcat context, and not have Apache serve static files. This helps insure that the behavior defined in the web.xml file functions properly. You can try by specifying JkMount / ajp13 and JkMount /* ajp13. Note that in spite of this, Apache will still serve an index.html without giving Tomcat a chance to serve the request. Hope this helps.

Each page (In its header) checks for the presence of of that session attribute before showing the page.

I just dont understand why this is not working. This makes
no sense to me. The startup command is working. I dont
understand why the stop command is not -- it uses the same

Anybody have any ideas?
Thanks,

I seeing messages for when tomcat starts up:

But, I dont see any messages among the shutdown messages in

/usr/local/jakarta-tomcat-3.2.1/bin/startup.sh
;;
*)
echo "Usage: tomcat {start|stop|restart}"
exit 1

exit $RETVAL
Next, I issued the following commands:
chmod +x /etc/init.d/tomcat

Re: Anyone got security-context working in Tomcat?
Craig:
Yes, that was it! Thanks!
To summarize for those that are still having trouble:
To make Tomcat require authentication for a give URL, add
these lines in the web-app tag in the web.xml file for
a tomcat application (NOTE: The URL pattern should not include the
application's context). Here is an example:
security-constraint
web-resource-collection
web-resource-nameAdminServlet/web-resource-name
url-pattern/servlet/AdminServlet/url-pattern
http-methodGET/http-method
http-methodPOST/http-method
/web-resource-collection
auth-constraint
role-nameadmin/role-name
/auth-constraint
/security-constraint
login-config
auth-methodBASIC/auth-method
realm-nameAdmin/realm-name
/login-config
security-role
role-nameadmin/role-name
/security-role
The passwords need to be placed in the
/usr/local/jakarta-tomcat-3.2.1/conf/tomcat-users.xml file:
user name="admin" password="[password]" roles="admin" /
Thanks,
Neil.

How to password-protect a servlet?
Hello:
I am using Apache 1.3.12 with Tomcat 3.1 and I wanted to
password protect a servlet running on Tomcat with the
Apache password mechanism.
In my httpd.conf file, I placed the following lines:
LocationMatch /videosearch/servlet/AdminServlet
AuthName "VideoSearch Admin"
AuthType Basic
AuthUserFile /usr/local/apache/conf/vidadmin.password
require valid-user
/LocationMatch
But, it did not ask me for a password. But, if I change the location
match to:
LocationMatch /test
AuthName "VideoSearch Admin"
AuthType Basic
AuthUserFile /usr/local/apache/conf/vidadmin.password
require valid-user
/LocationMatch
(The only thing I changed is the location to a directory called
test)
Everything works fine in this case.
Is Tomcat intercepting the URL before apache has a chance to
check if it needs to ask for a password?
Is there a way to use Apache's authentication for URLs that
point to Tomcat?
If not, does Tomcat have authentication capabilities?
Thanks,
Neil.
