RE: apache tomcat and ssl

[Ricky Leung]

Did you define jk directives in the SSL virtual host section of your apache
config file?  If you want https
to behave exactly like http, but just secure, copy your virtual jk
directives over to the ssl portion.

Also, make sure when you start apache, it doesn't complain about mod_jk
without EAPI support, you
will need that with SSL.

Depends on what you specified for the docBase parameter in the Context
element.  This needs to be the absolute or relative (to
$CATALINA_HOME/webapps) name of the WAR file.

Have you verified that your application's use of the path to the taglib
URL, in web.xml or in a <%@ taglib %> directive of a JSP page, do not use
this kind of invalid reference?

RE: RMI and TC4.x (Really classloader stuff)

[Greg Trasuk]

Hi David:

I'm in the same boat trying to use RMI and/or Jini from Tomcat.  This isn't
a complete answer to your question, as I'm still investigating the issue,
but I'm posting what I know so far in the hope that it might help in your
own solution, and also generate discussion that will guide my exploration.
When all is said and done, if there's interest, I can post a "Catalina-RMI
HOWTO" sort of document.

Although I didn't try to run the test case that you attached to your bug
report, I did take a look at it, and I think I know what's going on.  Here's
what I know so far (most of which you probably know already, but I'm
summarizing for other folks on the list):

When you pass an instance of some Serializable class as an argument to an
RMI call (e.g. passing a command object, as in your test case), the RMI
subsystem will serialize the object with an additional annotation indicating
the locations from which the class's bytecode can be downloaded.  When you
pass an exported object (e.g. a server object or an object that will receive
callbacks from remote objects), the RMI subsystem creates and serializes a
proxy object (otherwise known as the RMI stub object) in place of the actual
object.  In either case, the remote RMI subsystem has to load the class that
is called out in the serialized instance.  It does this by calling the
RMIClassLoader.

The RMIClassLoader object first tries to find the class locally (i.e. in
the default classloader).  If it can't find it locally, it searches in the
list of locations contained in the annotation mentioned above.  If the
required class is available locally, no further headaches are caused, which
may be why some people have had no problems using RMI under Tomcat - they
probably had the serialized classes and/or proxy classes in the standard
classpath/classloader setup.

And there we find our problem.  (At this point you might want to have a
look at the JSP snippet below) The annotation is determined by
RMIClassLoader. According to the "RMI and Object Serialization FAQ" in the
JDK1.31 API docs,

  "If the _Stub class was loaded by an RMIClassLoader, then RMI already
knows which codebase to use for its annotation. If the _Stub class was
loaded from the CLASSPATH, then there is no obvious codebase, and RMI
consults the java.rmi.server.codebase system property to find the codebase.
If the system property is not set, then the stub is marshalled with a null
codebase, which means that it cannot be used unless the client has a
matching copy of the _Stub classfile in the client's CLASSPATH. "

If we're running a standalone application (and I believe also in Tomcat
3.x), we're using the system class loader, which has "no obvious codebase",
so the java.rmi.server.codebase property gets used.  But what's the class
loader used in Tomcat 4.x?  I looked at the source code for Tomcat 4.0.1
(happens to be what I have on hand), and o.a.c.loader.WebAppClassLoader
extends from o.a.c.loader.StandardClassLoader, which extends from
java.net.URLClassLoader, which has a method called getURLs().  The
WebAppClassLoader.getURLs() method returns a list of all the repositories it
will search when trying to load a class on behalf of the web app.  This list
calls out all the jar's in WEB-INF/lib, common/lib, etc.

Having not seen the source for RMIClassLoader, I suspect that the
getClassAnnotation(..) method checks to see if the classloader for the
supplied class is a URLClassLoader, and if so, uses the results of the
getURLs() method call as "an obvious codebase".  This suspicion is supported
by the last part of the JSP, where I create a classloader that extends from
URLClassLoader but overrides getURLs() to return a phony url.  The phony url
shows up as the class's annotation.

So the exact error you quoted in the bug report shows something about a
"protocol missing" MalformedURL exception, which is caused by the fact that
the urls to the repositories contain spaces, since the RMI annotation is
supposed to be a "space-separated list of URL's".  Thus the annotation
doesn't get parsed properly.   This may be a bug in Catalina's class loader
(i.e. should the returned urls have the spaces encoded to '%20'?) or
possibly in the way RMIClassLoader uses the results of getURLs().  But it's
not the problem.

The problem is how to get our codebase into the annotation.  Clearly the
java.rmi.server.codebase property is not used, since the class loader has a
codebase.  But setting a system property doesn't feel right to me anyway,
since in a webapp scenario, we're in a shared JVM, and we shouldn't be
allowed to set system properties that will affect other webapps.  (Aside- we
similarly can't follow the normal practise of setting our own
RMISecurityManager, again since it doesn't play nice with the other webapps.
When I tried it, it seemed to screw-up Tomcat's internals, as well.  We need
to run Tomcat with security enabled, and set the approp

Re: Command line jspc throws NPE for page using JSTL

[Kris Schneider]

Hi Dave ;-),

I'm pretty sure it's meant to run standalone. The two "normal" ways I
know of are through the optional jspc Ant task or by running
%CATALINA_HOME%\bin\jspc.bat directly. Neither of those worked for me so
I went digging for some more detail about the failure. There's code in
the constructor of TagLibraryInfoImpl that strips a leading "/" off the
path before handing it off to JspCompilationContext.getResource which,
in turn, hands it off to JspCServletContext.getResource which explicitly
checks to see if the path starts with a "/".

unpacking of WAR

[Paul Phillips]

I worked on deploying my first webapp to another server today.  I packaged 
it up as a war, transferred it to the other tomcat server, added the one 
line context element in the server.xml, and restarted.  Nothing - the logs 
said that the webapp that was referenced by the context statement was not 
available or in a readable format.  In fact, the war did not expand into 
the file system.

So, I removed the context element, and restarted.  With the context gone, 
the WAR expanded properly.  Then I added the context back in, and it worked 
fine.

Is this normal?

Thanks
Paul Phillips

PS - the context element in the server.xml is just there to pass in a 
parameter containing the location of a data directory.

context problem with webapp connector

[Paul Phillips]

Tomcat 4.0.4 + Apache 1.3...

I have setup the mod_webapp connector and it sort of works...

However, I have a context in my tomcat server.xml file that looks like this:





Now, when I access my servlet directly into Tomcat standalone like this:

http://URL:8080/tester/etc -- the parameter is passed to my application 
just fine.

However, when I access my servlet through warp like this:

http://URL/tester/etc -- the parameter doesn't get passed.

I don't know why..

This is a stock Tomcat and Apache setup - the only thing I did was add 
mod_webapp and modify the apache configs according to the documentation.

Other than the parameter passing not working, the webapp connector seems to 
work.
-- that is:

http://URL/examples/etc work fine.

In a blind attempt to make it work, I added a   to the warp connector section near the bottom of 
the Tomcat server.xml.  That didn't seem to help any.

Any ideas?

Re: Command line jspc throws NPE for page using JSTL

Kris,
Did you find the code that refers to that path? Is it assuming that is 
runs inside a webapp container? If so, sound like it might be a bug 
(unless it was never intended to run standalone). I'd bet you could make 
it work by messing with your classpath.

I'm using jdk1.3.1_04, tomcat 4.0.4 on Linux 7.3 and I have link up
apache and tomcat using mod_jk2.

After I upgrade jstl from 1.0 to 1.0.1, I sometimes (not every time,
happen mainly after I update jsp files, clear cache and restart tomcat) get
the below error while trying to browse a jsp page.

I click on a link from a main page and the link is like this
http://mydomain/application/  (by default it will search for index.jsp)

and the browser address bar will return somthing like below
http://mydomain/application;jsessionid=42735B0A5AABE2DC6DA7212272E3CC3E
with a Page not found error.

but things will back to normal after I restart tomcat and clear cache again.
Sometimes, I can just go back to the main page, refresh my browser and
things will back to normal too without restarting tomcat.

I can't figure out what is the cause as it is not happenning all the time.

Command line jspc throws NPE for page using JSTL

[Kris Schneider]

(Alrighty, this is actually attempt number 3 to get this note posted.
Gotta get more caffeine to the gerbils powering the email server...)

When I try to use jspc from the command line to compile a JSP page that
uses JSTL (1.0.1), I get a NullPointerException. Here's the setup
(apologies if my email client hoses long lines):

JAVA_HOME=C:\jdk1.3
CATALINA_HOME=D:\jakarta-tomcat-4.1.8
JASPER_HOME=D:\jakarta-tomcat-4.1.8

Here's how jspc gets invoked and the resulting error:

WEB-INF\src\jspc -webinc WEB-INF\jspc-web.xml -uriroot . -webapp .

JSPC Test
Welcome to the JSPC test page


Here's web.xml:

index.jsp



The only other components of the app are the JAR files for JSTL that are
installed in WEB-INF\lib. Everything works fine running as an app under
4.1.8. Any ideas about what's going on? Also, does the "v" flag really
do anything? I can't seem to get any verbose output no matter what it's
set to. Thanks for any help.

That's still not going to work for what the proposed use case was --
because you've just disabled the default file-serving servlet that serves
static content.

If you use a "/*" mapping, you won't see anything in getServletPath(), but
check out getPathInfo() -- that's defined to give you "everything in the
request URI after the part that matched my servlet."  Because the part
that matched your servlet in this case is a zero-length string, you'll see
all the stuff you want.

You will soon find out that a servlet mapping is not what you want here.

Consider the case of a JSP page.  The "*.jsp" pattern is mapped to the JSP
servlet, but a "/*" mapping intercepts those requests, and there's no way
to get from here to there.

Your answer would be to use a Filter instead of a Servlet (requires a
servlet 2.3 container like Tomcat 4 or later).  You can map a Filter to
one or more URL patterns without interfering with which Servlet is
ultimately responsible for processing the request.  A Filter can do things
like inspect the request (or the appropriate session) and do things like
redirect if the user is not logged on (by doing a
RequestDispatcher.forwrd()) or passing the request through in the normal
case.

You could always parse the output of task, or use grep to look for the

Such a facility doesn't exist yet, but would make a nice enhancement.  To
make such a request, the bug tracking system is a good bet:

Although it's an Ant-sounding question, the Ant tasks we are talking about
are actually part of Tomcat (nobody on ANT-USER would probably have any
idea what you're talking about), so this is the right place.

Ant lets you plug in your own custom tasks, and we took advantage of that
capability here.

For any version of Tomcat, you can put your own  entry into
server.xml, even if the application is in webapps -- the standard Tomcat
distribution does this for the "/examples" webapp.

For Tomcat 4.1, you can also locate the  element in a separate
file, and customize it as needed.  If you put this context configuration
file, instead of the directory or WAR, into webapps it will still get
auto-deployed.

upgrading from v.3.1.1 to v.3.3 ?

[Paul Tomsic]

What's involved w/ an upgrade of Tomcat from 3.1.1
to 3.3?

Is this a fairly straight forward task, or is it quite
involved?
We're experiencing some "odd" behaviour from 3.1.1,
and can't help but wonder if it's got something to do
w/ the old version.

Unfortunately, we're in the middle of a crunch
deadline, so if it's as simple as say, swapping out a
jar file or something, that would be great.

Thoughts, or can someone point me to a FAQ on
upgrading like this?

Thanks,

RE: Servlet to JDBC connection

[Mike Jackson]

I don't know for sure, but in my experience the jdbc urls typically 
don't have the path on the disk referenced.  Rather they usually
have the database name listed, or no name (ie default database).  
So I'd check your docs for interbase and make sure that your url
following the slash after the port is correct.

Also, if your database is running on the same machine as the web
server then consider using the loopback address instead of the the
"real" ip address of the server.  Sometimes that'll be more efficient.

The code looks alright...

Do the example servlets work? Try putting the .class file in with the

.class file:  Tomcat/webapps/examples/WEB-INF/classes
URL:  http://localhost:8080/examples/servlet/ExampleServlet (or "HelloWorld"
just to make sure it works).

Hope that helps!

The saga continues.

Downloaded Tomcat 4.0.4.  Couldn't get it to work even with the examples.

Desperate.  Downloaded Tomcat 4.1.8.  Worked with the forward

after a little tinkering with the code, it worked.

The interface with Forte is just a little funky as I can't compile directly
from Forte.  But I can run from Forte and the logs display properly, so it
looks like I am finally able to proceed.

Still the question remains: why wouldn't Tomcat 4.0.1 (the version in the
Forte download work with the  tag construct.

This is the same issue I have been working on all day. I finally got it to
work about an hour ago. (FYI: I am running fresh install of Apache 1.3.22
and Tomcat 3.3.1 on Windows 2000 Pro. Apache is running as a service and
using mod_jk to support Tomcat.) You are 80% home based on your description.

Questions:
- Does your jsp work if you throw it into the examples\jsp folder? 
If it runs in one folder but not another, make sure you have your directory
layout formatted according this deployment guide:
http://jakarta.apache.org/tomcat/tomcat-4.0-doc/appdev/deployment.html.
- What does the Apache error log say?
- What is your Apache-Tomcat glue (mod_jk, etc)?

ant task to query if a particular app is running?

[Jacob Kjome]

Hi,

I'm wondering if it is possible to use one of the catalina ant manager
tasks to query for the existence of a single running application.  The
closest thing to it that I can find is the "List" task.  However, that
just returns a string list of all running apps.

What I would like to do is be able to make my "install" target check
whether an app is already loaded.  If so, instead of just saying
"already installed" and ending the build, it would run the "reload" target.
This would save timeor is it possible to catch some error
condition from the install target and conditionally run the "reload"
target if the install target returns that error condition?  If so, how
is that done?

Note:  I'm sending this mostly Ant question to the Tomcat-user list
only because people like Craig know more about the manager app and the
catalina tasks than the Ant people do.

thanks,

Jake

bytes.  I can reproduce this on my laptop (W2K Pro, P3) in both IE 5.5 and
Navigator 4.75.  On my tower (W2K Server, P4), I can reproduce on Navigator
4.79 only and it works in IE 5.5.

Ignacio,

I can't provide a test case because my servlet is calling a component from
an application server.  The HTML is actually built in the component, within
the application server, and returned to the servlet, web server and
ultimately to the browser.

Basically, some of the HTML pages are around 30-50k in size.

500 error on all JSP pages

[Kenny G. Dubuisson, Jr.]

Hello all.  I'm new to the list.  I'm getting a "500" error on any JSP I try
to run.  If I run the servlet examples though, they seem to work fine.  I
realize that this is like the most common error and I know it's just a
config issue, but darn if I can find it.  Any help would be very appreciated
(bowing down in complete reverence is probable).

FYI:  This is a fresh install of Apache 1.3.26 and Tomcat 3.3.1 on Windows
NT.

Thanks,

JSSE/mod_ssl or wrong mailing list

[AMRAN121]

I posted this a couple of days ago and so far I have had no response so  am I 
asking a wrong question in the wrong mailing list does anyone know of a 
better place where my tomcat ssl encryption questions can be asked?

I had been following the recent disscusion of login + ssl which has been very 
useful info for me.

Also does anyone know which is better to use the mod_ssl or JSSE




ORIGINAL MESSAGE

HI

I have just followed the Tomcat SSL HOWTO and I am able to get my 
https://localhost:443/ page. I then right-click on my mouse to get up the 
page properties; 

Protocol:Hyper Text Transfer With Privacy
Type: HTML Document
Connection:Not Encrypted
Address(URL):https://localhost:443/index.html
Size:  2572 bytes


but it says the page is not encrypted why does this happen? should it not 
state some sought of encryption like 128 bit?

I also tried the Apache + mod_ssl HOWTO and I do get an encrypted connection 
which says the following;

Connection:TLS 1.0, RC4 with 128 bit encryption (High); RSA with 1024 bit 

exchange

I have apache 1.3.26 (Linux box) + mod_jk + Tomcat 4.04 (Windows box)

The Tomcat server in my environment handles login forms processes them and 
then puts the user to their homepage. I wish to encrypt this login process. I 

don't think I need to use apache +mod_ssl to do any connection encryption 
because the login form is sent to the Tomcat server.  

I cannot figure out what I am missing? Can anyone help please?

Thanxs in Advance

Tomcat4 : specific settings for Context

[Dominique Deleris]

Hello list,

I would like to setup some specific settings per Tomcat
Context. Debian flavour for Tomcat automatically detects all apps
deployed in /webapps and sets up all needed
settings : there is no  entry in server.xml for the
different applications.

Now I woul like to setup the "reloadable" attribute for a
specific application in Tomcat : how should I do, since I can not
find anything related to my application Context in Tomcat config
files...

I hope this was clear enough :-)

RE: Tomcat, JAXB and SecurityManager

[Extance, Paul]

We have had a problem with JAXB under Tomcat 4.0.3, as it couldn't find the
jaxb-rt.jar in the WEB-INF/lib folder. 

We also put it in the %catalina_home%/common/lib, and it still couldn't find
it.
We then put the jar in the %java_home%/jre/lib/ext and then it worked.

We then upgraded to Tomcat 4.0.4 and the problem went away.

So if your getting a 'ClassNotFound' exception this may help.

Re: Converting HOST to IP an IP to HOST

The case is that I whould not like to do somithing like

You're correct -- the actual context path name is set from the "path"
attribute of the  element.  But following the convention
certainly reduces the potential for confusion.

tomcat + apache

hola estoy intentando , en mi linux suse 8, hacer andar el tomcat con el
apache, es decir que el puerto 80 tambien responda a las peticones jsp y no
lo consigo.
para ver las jsp tengo que poenr 8080.
bien el el httpd.conf de apache tengo:
LoadModule webapp_module /usr/lib/apache/mod_webapp.so
WebAppConnection tomcat warp localhost:8008
WebAppDeploy examples tomcat /examples
WebAppInfo /webapp-info
# The following line prohibits users from directly accessing WEB-INF

AllowOverride None
deny from all


el documentoRoot de apache esta en /usr/local/httpd/htdocs. Como puedo hacer
andar en el puerto 80 unas paginas jsp que estan el:
/usr/local/httpd/htdocs/admin ?
el documento root de tomcat esta en /opt/jakarta/webapps/ROOT

Me podeis ayudar con esto?

llevo dos semanas con ello y no consigo tirar adelante.
Me imagino que hay que hacer varias cosas:
1.- editar el httpd.conf de apache y añadir un conector con un puerto
2.- editar el server.xml y añadir un contexcto pero por mas que hago pruebas
no consigo ver el admin.

Me podeis ayudar?

RE: using INCLUDE with crossContext

The include directive is relative to the webapp.  This is as specified
in the JSP Spec.  From my understanding, you can use the 
to retrieve files from other contexts.

RE: Is it possible to include via a directive snippets into the server.xml file

[Andrew]

actually, I don't believe that the name of the xml file has to be the
context name, but don't quote me on that.  The important information is
the context information within the XML file.  From my understanding, you
just have to use  as your root element, and you can add any
sub elements necessary.

Within our project we have an overlap of responsibility between the 
infrastructure team who are responsible for building the application 
servers and the development team who are responsible for delivering an 
application ready for deployment. 
The overlap centres on server.xml 
The infrastructure guys need to put host specific information into 
server.xml 
The development guys are dependent on a context definition and resources

defined within it. 
My question is therefore ... is it possible to "include" a snippet for 
the context that the development team can maintain into the

RE: Converting HOST to IP an IP to HOST

[Turner, John]

Well, so far you've asked two different questions, yet they are supposed to
be the same.

Your first post wanted an IP address from a name, getByName() will do that
for you, assuming by "name" you mean fully-qualified internet domain name.  

Now you are saying that the IP address will actually be in the URL, in which
case you don't need to look it up, so it's not clear what you are trying to
do.

If you need to differentiate content based on whether someone accesses a
resource by IP address or name, and there are many possible IP addresses,
then all you have to do is test if the value returned from getRequestURI()
has an IP address in it.  So rather than look for a specific IP address, all
you have to do is look for ANY IP address.  That will tell you if someone
entered the machine name or not.  

If you need something to translate a Microsoft WINS name (server name) to an
IP address, you'll need some sort of Java WINS library...check google...my

Subject: Converting HOST to IP an IP to HOST


All right, but it does not solve my problem. I did a local
 web system that can be accessed both by IP or HOST.
 Depending on the way the user accessed( by HOST or IP )
 the application I must display different contents. 

I could do this:

if(
 request.getRequestURL().toString().equals("192.168.20.10")
 ) 
 out.print("show IP content"); 
else 
 ou.print("show HOST content");

But the web server has many network devices and the user
 can accesss the system from many other IP and HOSTs.

The InetAddress.getByName() does not work with the machine
 network name only with inet hosts.

Does anybody has any idea ???


Thanks in advice,
Junior

RE: Configuration for High TPS

[Marinko, Jeff]

Thanks Mark!  That's some good advice.  I haven't moved on to "tweaking" the
JVM yet, I know there are some options I can use to increase performance,
but I'm not to that point yet.

I'm sticking with the standalone for simplicity.  I'll likely turn this over
to someone else, and the fewer parts, the better.  We examined using Apache
and JServ, and a coworker informed me the installation wasn't that
straightforward.

The logging tip is a good one, thanks!

We ran some high TPS testing recently using a Sun 220R running Solaris
8. We were running an Apache/Tomcat combination using the mod_webapp
connector.

Just running a dumb simple servlet we were topping out at 165 tps and
80% CPU.

We tried repeating the test using Tomcat standalone trying to figure out
where the bottleneck was. We still topped out at 165 tps despite
everything we tried to tweak. Our CPU was drastically reduced though to
40%.

After running some e-mails through this list, the consensus was that we
needed to tweak with our JVM as this was probably the cause of our
"ceiling". Not the web server configuration and not the horsepower on
the machine. Actually, in standalone mode, we could not drive our CPU
load beyond 40%.

So far, we haven't had a chance to research this further and our
production app is not pushing any limits just yet so its on the back
burner.

By the way, check how much stuff your Tomcat installation is logging.
The default configuration is pretty verbose and this consumes large
amounts of horsepower writing it all to disk. WinNT isn't overly good at
walking and chewing gum and a lot of disk activity can drain resources
pretty quickly.

Have you integrated Tomcat with another webserver for the static

RE: Connection/acceptCount Problem

[Marinko, Jeff]

JDK:  1.4 and 1.3.1 (currently 1.4)

OS:  WinNT 4, no service packs on test machine

enableLookups: Maybe slight improvement.  I already stated it could handle
150 TPS with it set to "true".

test tool:  custom program.  I did not write it, only using it.  Not running
IIS, but I'm pretty sure it is not the tool.  Currently "testing" Tomcat
versus some custom C++ code (using the same tool for both), and the
connection problem does not happen with the C++ code.

Like I said before, I'm pretty sure it's Tomcat. Once the problem starts
happening, Tomcat's CPU usage nearly doubles when running relatively low TPS
values (like 40).

You really aren't giving enough detail in your messages. You are trying to
treat a complex problem (hundreds of transactions per second) as a simple,
something is wrong with one thing issue. Scaling performance to these levels
is usually a combination of factors. There are rarely magic bullets when it
comes to things like this.

What JDK are you using? Have you tried using different JDKs?

What operating system are you using? You said WinNT in your initial post. Is
that WinNT 4? What service packs have been applied?

You never posted a response as to whether setting enableLookups="false" made
any difference.

What test tool are you using? Are you sure the issue is in Tomcat, and not
in the test tool/station? I assume you have IIS installed. Have you tried
using the same test tool to put 200 connections per second to IIS?

Have you tried scaling your transactions per second upwards and observing
the behavior at different loads?

Subject: Connection/acceptCount Problem


I've mentioned this before in my Configuration e-mail, but it appears
important enough for me to mention it again (as there hasn't been a
response, and it is a pretty serious problem IMO).

When I run tests at a high TPS, I might encounter a "can't connect" error
(looks like I've reached the acceptCount limit).  That's fine with me, so I
stop the test and get ready to start another.  When I start the next test (I
usually wait a few seconds, let tomcat's CPU usage drop off), I immediately
start getting "can't connect" errors, which should not be possible in the
amount of time I'm getting them (TPS of 100, acceptCount 1000, that should
be 10 seconds before I should get these errors, right?)

My only "fix" for this problem is to shutdown and restart Tomcat, which is
not really a solution.

Is this a known problem or bug? Possible I misconfigured something?

One particular thing you will want to do is kill the access logging that
was turned on by default through 4.0.2 or so -- simply comment out the
 element that defines the AccessLogValve in server.xml it is
enabled.

As you've undoubtedly discovered, the JAAS spec doesn't provide any
guidance for figuring out which Principal is which in the Subject that
gets returned.  Looking inside some of the existing implementations (such
as the one that can access an NT domain), this was being done by hard
coded instanceof checks on particular Principal subclasses.

So, to generalize this a little, JAASRealm lets you declare the fully
qualified class names of classes that represent your roles (in the
"roleClasses" property).  You can see it used in the createPrincipal()
method inside JAASRealm, where it is checking the classname of each
returned Principal against the list of class names you provided.  When it
finds a match, it assumes that principal.getName() on that Principal will
return the role name that has been authorized for this user.

The "userClasses" property serves a similar purpose for saying which
classes actually represent the user.

NOTE:  The implementation classes themselves need to be visible to
Catalina's internal class loaders for all of this to work.  The simplest
thing to do is put them in a JAR file in $CATALINA_HOME/server/lib, or as
unpacked classes under $CATALINA_HOME/server/classes.

NOTE:  You won't see any direct references to the setRoleClasses() or
setUserClasses() methods.  The code that parses server.xml (the Digester
module) has magic code (well, it's actually separately available in
commons-beanutils :-) in it that matches up attributes in the XML
elements to the corresponding property setters in the class.  So, you
configure one of these beasts like this:

  

and the setter gets called for you via Java's introspection and
reflection capabilities.

Re: java.endorsed.dirs

Hello Neo,

Well, you can upgrade to Tomcat-4.1.x where they now include a
$CATALINA_HOME/common/endorsed directory.  Or, you can use java's
standard endorsed dir: $JAVA_HOME/jre/lib/endorsed

Not sure how to add your own endorsed directories, though.  Maybe
Tomcat-4.1.x will understand the -Dendorsed.dirs flag since it now
provides the common/endorsed directory where Tomcat-4.0.x didn't.

else 
 ou.print("show HOST content");

But the web server has many network devices and the user
 can accesss the system from many other IP and HOSTs.

The InetAddress.getByName() does not work with the machine
 network name only with inet hosts.

Does anybody has any idea ???


Thanks in advice,
Junior

RE: Connection/acceptCount Problem

[Sexton, George]

You really aren't giving enough detail in your messages. You are trying to
treat a complex problem (hundreds of transactions per second) as a simple,
something is wrong with one thing issue. Scaling performance to these levels
is usually a combination of factors. There are rarely magic bullets when it
comes to things like this.

What JDK are you using? Have you tried using different JDKs?

What operating system are you using? You said WinNT in your initial post. Is
that WinNT 4? What service packs have been applied?

You never posted a response as to whether setting enableLookups="false" made
any difference.

What test tool are you using? Are you sure the issue is in Tomcat, and not
in the test tool/station? I assume you have IIS installed. Have you tried
using the same test tool to put 200 connections per second to IIS?

Have you tried scaling your transactions per second upwards and observing
the behavior at different loads?

Subject: Connection/acceptCount Problem


I've mentioned this before in my Configuration e-mail, but it appears
important enough for me to mention it again (as there hasn't been a
response, and it is a pretty serious problem IMO).

When I run tests at a high TPS, I might encounter a "can't connect" error
(looks like I've reached the acceptCount limit).  That's fine with me, so I
stop the test and get ready to start another.  When I start the next test (I
usually wait a few seconds, let tomcat's CPU usage drop off), I immediately
start getting "can't connect" errors, which should not be possible in the
amount of time I'm getting them (TPS of 100, acceptCount 1000, that should
be 10 seconds before I should get these errors, right?)

My only "fix" for this problem is to shutdown and restart Tomcat, which is
not really a solution.

Is this a known problem or bug? Possible I misconfigured something?

Tomcat 4.1.x JAASRealm Implementation

[James Krygowski]

Hey All (Craig particularly)-

Going through the code that exists in 4.1.8, I noticed that in the JAASRealm
comments, Craig makes mention of using classes implementing the Principal
interface to represent Users and Roles.  This sounds like a good approach
given the vagueness surrounding the JAAS implementation once you get into
implementing it.  In the JAASRealm class, there are setters for configuring
the JAASRealm with the names of Principal classes that contain Users and
Roles.  After running a "Find Usages" with IDEA, I wasn't able to find any
code which references these methods.  So, how does the JAASRealm find out
what classes contain users vs. roles?  Is there some kind of magic going on
with the realm config node in server.xml?  I'd like to start using JAAS on
Tomcat since we currently use JAAS for our JRun servers and converting the
existing LoginModules won't be too much of a pain.

RE: Configuration for High TPS

[Marinko, Jeff]

I plan to do pre-caching later.  Currently my "first" test run is the
unlucky user, which I'm calling a "cold start" and seeing how well it
performs from a clear cache.

No, I'm running TC stand-alone currently.  Running it with Apache will
improve performance? I'll look into it, but for now I'm running stand-alone.

Have you integrated Tomcat with another webserver for the static content,
assuming you have some.  That would more than likely improve performance.

RE: Configuration for High TPS

You can set up an event listener to cache this data when the context is initialized.  
That's probably better than making the initial unlucky users wait.

Precompiling JSPs for Tomcat

[Sean LeBlanc]

Hi all, 

I'm having some issues with using Ant's  task (I have a thread going
on the Ant mailing list), is there any way to manually call the compilation
for Tomcat's build? Somehow, Tomcat must do it, so I figure there has to be
a way to kluge something together that does the same thing?

I'm attempting to configure Tomcat for a test environment to handle a high
number of transactions per second (TPS) and would like any advice others may
like to contribute.  The machine is a fairly powerful dual processor machine
(1+ GHz) running WinNT.  I'm using a tool to send requests, where I can
specify the TPS and number of requests total to send.

I'm running the following with "ok" results, but I'm interested in any
suggestions or better explanations of some of the fields:



Perhaps my biggest problem is the number of connections Tomcat accepts fills
up rather quickly, some of the connections my tool generates are refused
(presumably due to the acceptCount limit being reached, and I have increased
it a couple times).

Any advice would be appreciated!

it looks like you have an xml parser conflict ( tomcat's xerces and the
jdk's xml parser ).

either download tomcat4-LE-jdk14 or reorder your xml parser's jar files in
your classpath ( ie put xml-apis.jar, xercesImpl.jar first in your
CLASSPATH). check xerces' documentation for further info.

As far as I know, the connectors aren't tied to specific tomcat versions
(separate projects).  If memory serves, that resource is the same resource
that has always been posted under the 4.0 docs.

Where can I find documentation on the Coyote connector (such as the exact

What is really bothering me (currently), is once I start getting connection

I'm pretty sure that you can in fact use it with 4.0.*. You may have to
compile the connector distro in order to get it, but once you have the
necessary classes it should drop in with no problem.

RequestDispatcher question

[Scott Purcell]

Hello,

I am trying to send a (request, response) object to a server that lives at another IP 
(or URL). I have the need to pass parameters that are in the request object, but I 
cannot seem to forward the request to the other servlet. I keep getting a error: 
"java.lang.IllegalArgumentException: Path 
http://xxx.xxx.xxx.xxx/testcode/servlet/allparams does not start with a "/" character 

When I try the same code on my local machine, within the same web app, all works 
great. So I think the coding is good.  So I am trying to figure how to get the request 
object from one box to another? Any ideas?

Thanks,


Test Code:
// from a method here
try {
gotoPage("http://XXX.XXX.X.XXX/testcode/servlet/allparams";, 
request, response);
response.sendRedirect(mm.getSomeURL());
}


private void gotoPage(String address,
  HttpServletRequest request,
  HttpServletResponse response)
throws ServletException, IOException {
RequestDispatcher dispatcher = 
getServletContext().getRequestDispatcher(address);
dispatcher.forward(request, response);

java.endorsed.dirs

[Neo]

How can I configure my custom instance of the Tomcat service to append my
endorsed.dir?  I tried adding the flag (-Djava.endorsed.dirs='') to my
tomcat service installation script but the value is ignored by tomcat once
it starts up.

I stumbled across a couple web pages that lead me to believe it is not
possible to accomplish this given the current Tomcat classloader
implementation.  If that is indeed the case...has this issue been address
and what version of Tomcat can I find it in?

I'm using Tomcat 4.0.4 on Win32.

Thanks in advance,
Neo

Re: Error 500 need help

[Carlos Ferreira]

it looks like you have an xml parser conflict ( tomcat's xerces and the
jdk's xml parser ).

either download tomcat4-LE-jdk14 or reorder your xml parser's jar files in
your classpath ( ie put xml-apis.jar, xercesImpl.jar first in your
CLASSPATH). check xerces' documentation for further info.

RE: Configuration for High TPS

[Marinko, Jeff]

I knew I forgot a detail Running Tomcat 4.0.3 (or 4.0.4, I'll likely
upgrade to that version soon).

Quick follow up on this.

I'm testing a servlet I've written that does some caching, and is very quick
once it has cached all of its data.  During the first run, I test it going
40 TPS (over several thousand requests).  Then I start upping the TPS (same
set of requests), and I plan to stop at 200 TPS.

Now here's an intresting problem.  My tool has reported on several runs that
it cannot connect within only a second or two of starting the tool.  With an
accept count of over 1000, I find this rather odd as it should take at least
5 seconds at 200 TPS to fill an "acceptCount" of 1000 (typically the lowest
I've set acceptCount).  I normally run into can't connect errors early
during a test run, when my servlet is still caching its data (still working
on a way to better handle that problem also).

Any insight would be appreciated.  Thanks!

Jeff

Andy,

I've not run into the same problem, but had some
problems (more GUI related) with sun jdk version 1.4.0.

I upgraded to sun jdk version 1.4.1beta and the problems
disappeared.

I don't know what version you're running, but if its 1.4.0
you may very well benefit from doing the same.

RE: RE: Problems with class loader

[Cox, Charlie]

ok, StandardClassLoader means that the class is trying to be loaded from
\tomcat\lib. If it were being loaded from \web-inf\lib, it would be
WebappClassLoader throwing the error.

>From your stack trace, it looks as if it is loading the Hashtable ok(through
reflection), but it is the contents of the hashtable that can't be loaded.
This would make sense since you put the Hashtable in \tomcat\lib.

How about if you try to put Hashtable in the \web-inf\lib so that the first
reflection call will find it in the current(webapp) classloader, then the
second reflection call(from hashtable) will occur in your webapp's
classloader. Of course being a java class, I'm not sure if it will have
problems being(or can be) loaded multiple times.

Re: jsp include question

[Jose Francisco Junior]

If you want to redirect the request you have to do it
 before printing any other thing on the page.

Example:

jsp:forward revisited

[Carl]

Thank all for your responses but I am still in deep doodoo as nothing has
worked.

On the suggestion that the location of the page to be forwarded to was
incorrectly specified, I have tried all combinations of means of specifying
the page and nothing helps, does not change the error.

On the suggestion that I download Tomcat 4.0.3 (I am using Forte 4 with jsdk
1.4), I could not find a place to download Tomcat 4.0.3 but did download
Tomcat 4.0.4.  No help, Tomact 4.0.4 won't even run its own samples as it
fails as follows:

Anyone have any ideas why the Servlet jsp is marked unavailable?

My core problem remains as moving from one jsp page to another using the

I am trying to bring up an application that has over 400 pages with that

On an "http" connection, anyone who has access to the physical network can
snoop packets and see what is going on.  That's why you're trying to
encrypt the username and password in the first place, right?

The problem is that username/password is not the only sensitive
information going back and forth -- the session identifier is also passed
up to the server on each request, either in a cookie or as part of the
URLs.  This is how the server knows that a subsequent request belongs to
the logged-in user.  Anyone who knows the session id can impersonate the
logged on user, and do anything that user is allowed to do.

If you switch back to "http" after logging in, that means the session id
will get transmitted in cleartext (and, no, there's nothing you can do to
encrypt *just* that).  Therefore, any snooper on the network can see this
session id and start submitting their own requests with that session id.
The server thinks that you've already authenticated, so it lets you do
whatever you want.

All the snooper has to do is wait for someone to log on, observe their
next submit to the server, and snarf the session id ...

The bottom line is that using SSL only for the username/password is a
total waste of time from a security perspective.  If you're not going to
encrypt the entire conversation (which includes the session ids), don't
even bother trying -- you will only get the illusion (or should I say,
*delusion*) of being more secure.  In reality, you'd accomplish
nothing useful.

A more general statement of the principle:  once you switch a session from
"http" to "https", you should never again accept a non-https request for
that same session.  Applications that don't obey this rule are hopelessly
insecure, and should be avoided like the plague.

Authentication: Use Tomcat and Apache

[Kevin Andryc]

I have an application that currently uses Apache's authentication. In order
for this to work with Tomcat I had to specify it in my server.xml, like so:



I also have another application running under Tomcat that I would like
Tomcat to handle the authentication. Is there a way to have both methods?

One approach is to do what Tomcat 4.1 itself does for the admin and
manager webapps -- for a context at path "/foo", create a "foo.xml" file.
If you put that in $CATALINA_HOME/webapps, it will get auto-deployed.

XML lets you do stuff like that directly with entities.

In Tomcat 4.1.x, you can also separate out the  element for each
context into a separate "context configuration file" that can be
independently deployed, which would seem a better long term solution.

If all else fails, you can write a simple script that combines all the
stuff you need from file fragments just before invoking the startup.
Sometimes the simple solutions are the best ...

Another approach to consider for this kind of use is the "User Home
Directories" capability (requires Tomcat 4).  This makes a URL like
"http://www.myhost.com:8080/~craigmcc/"; refer to the "public_html"
subdirectory of my user home directory (just like the similar feature in
Apache and other web servers).  At startup time, all the users who have
public_html directories accessible to the username Tomcat runs under will
be automatically recognized.

Documentation is on the Host page in the server configuration reference
(http://localhost:8080/tomcat-docs/config/host.html).

AW: migrating from gnuJSP to tomcat 4/apache 2

[Ralph Einfeldt]

As I'm on the same road, here are my thoughts
(I didn't start trying it, that will not be so 
soon as we feel not pressure to do the switch):

If you have just one context (that what we will have)
you can do the following:

  - Keep your htdoc as it is.
  - Define a default context:
)
  - Deny the access of apache to webapps/{context}/WEB-INF
  - Use the JkMount selectively:
JkMount /*.jsp ajp13/ajp14
JkMount /servlet/* ajp13/ajp14

If you want to have more than one context you may have 
to change all references to static or dynamic resources
in the jsp's to contain the context name. (As we don't 
use relative path's I don't know what happens with them)

I don't know if this enough, but it should be the right 
direction.

??? Bug in Tomcat Response Headers ???

[Tony LaPaso]

Hello all,

I posted this a few days ago but received no responseIf
someone intimately familiar with Tomcat internals (liek Craig M.)
could comment I'd appreciate it.

I'm not 100% sure about this but I think I found a problem with
the way Tomcat encodes characters. First I'll explain what I
think the problem is and then I'll say why I think it's a
problem. Please keep in mind that I'm not looking for alternative
solutions (i.e., please don't tell me to use UTF-8). I want to
stay focused on the problem. The behavior I'm seeing is not
correct, IMHO.

Assume I have these three lines of code in my doGet():

response.setContentType("text/html;charset=UTF-16");
PrintWriter pw = response.getWriter();
pw.print("Test" +
 "");

The PrintWriter returned from response.getWriter() will encode
all characters as UTF-16. This means that all the response body
(i.e., the HTML) gets encoded as UTF-16 before being sent to the
client. So far, so good.

Here's the problem: The reponse headers generated from the
servlet *ALSO* get encoded as UTF-16, which, I believe is in
violation of the HTTP spec. In reading the HTTP spec, response
headers should be encoded as US-ASCII.

So, it seems that Tomcat (or perhaps the Servlet API
implementation) needs to be modified so that the response headers
are *always* encoded as US-ASCII, regardless of the encoding for
the response body.

Again, please do not offer "ways around" this or ask me why I'm
sending UTF-16 encoded characters. I know UTF-8 can be used but
that's not the point.

Is this a bug or am I buggy?

Thanks,

For stress testing use Apache JMeter.

migrating from gnuJSP to tomcat 4/apache 2

[Steve Prior]

I have happily been serving JSP pages from Apache 1.3/jserv/gnuJSP
for over a year now, and am starting to become motivated to move
to Apache2/Tomcat.

With GnuJSP I could have JSP files anywhere I wanted under the htdocs
directory for Apache and they would be passed to GnuJSP, but all
other files (html, jpg, shtml, whatever) would still be handled by
apache.

I have Tomcat already connected using mod_jk2 to apache2 so that I
can go to http://localhost/examples/jsp/whatever so it appears to
be functionioning mostly right.  What I cannot and really want to
do is to be able to put JSP files anywhere in the apache tree (like I
used to) and have apache pass them off to tomcat, but handle everything
else by itself.

Is this even possible with the new architecture of Tomcat?  I have so
many JSP pages scattered throughout my site that it seems that if every
directory that uses JSP pages needs to be handled by tomcat that I
won't be left with apache handling anything by itself.

Thanks
Steve
