Re: mod_jserv or mod_jk

2001-03-22 Thread Martin Mauri



Both of them are servlet containers.

The difference is in the version of the servlet specifications. JSERV is a
Servlet 2.0 compliant servlet container while Tomcat is a Servlet 2.2
servlet container. Tomcat is more advanced and efficient than JSERV.
Furthermore, mod_jserv was thought to be a connetor between JSERV and
Apache, when Tomcat first came, a version of mod_jserv was adapted to work
with Tomcat. But it had lot of bugs and wasn't so robust. A brand new module
was built for Tomcat-Apache connectivity and was called mod_jk. I'd suggest
using Apache-Tomcat-mod_jk.

HTH,

Martin

PD: Any mistake in my explanation, please correct!

Client Authentication via Tomcat

2001-03-22 Thread R.W. Shore


There have been various posts regarding Tomcat's inability to successfully
complete client authentication, particularly with Microsoft's IE. We've
discovered the answer to Tomcat's problem. It turns out that as part of the
client-cert request in the standard SSL protocol, the server side sends a
_stringified_ version of each trusted certificate. The string version is a
standard representation of the distinguished name of the signer of a trusted
certificate, such as CN=Templar Corporation, OU=Software Development and
so on.

Now, it appears that IE does a simple string comparison of its trusted certs
against this list to figure out what certificates are trusted. IE doesn't
look at the certificates themselves (which are also included in the SSL
handshake) during this initial screen - it looks simply at the stringified
version of the signer. This means that if there's any difference between the
way that the server stringifies the signer and the way IE stringifies the
signer, IE's match fails, and IE will never recognize the trusted
certificate.

With this background, the problem turns out to be the following:

(1) The Microsoft certificate authority allows an email address in the root
certificate's distinguished name. This isn't exactly standard (my reading of
the DN standard is that only an X501 item can appear in the DN and there
isn't a clear item for email address) but it is very common.

(2) When Microsoft stringifies a certificate's signer, it uses "E=" as the
marker for the email address.

(3) When Tomcat stringifies a certificate's signer, it uses "EmailAddress="
as the marker for the email address.

(4) Since IE and Tomcat don't agree on the stringified version of the email
address, IE's string match fails to recognize a root certificate that
includes an email address.

The fix: we re-installed the Microsoft cert authority and specified a
distinguished name for the authority that did not include an email address.
After re-installing the certs in both Tomcat and IE, the two were able to
exchange a client cert without a problem.

I speculate that Netscape looks for trusted roots in the SSL handshake
differently, which is why we were able to get client authentication working
with Netscape, even with the email address in the root.

error 404 tomcat/IIS

The strange thing is that a restart of the computer where the site is hosted

And if i reload the first page again it's also error 404.

Re: configuring Tomcat on Windows 2000 and IIS

2001-03-22 Thread Salvatore Borrelli

Hi Carlos,
if you want to add another
context to your webapps, you need to follow the instructions given into the
tomcat-iis-howto.html document (search for the "Adding additional contexts"
paragraph), i.e. :

1)add your context to the ISAPI redirector
editing the uriworkermap.properties file as described in the
document
2)restart IIS as described in the step 5 of
my previous mail and it will (or at least it should :-) serve the new
context

Clearly you must already have added the context to
Tomcat (for the /admin context you don't nedd to do that, thus simply add the
context to the ISAPI redirector).

Delay (40 seconds) on first jsp access

2001-03-22 Thread James Carroll



Delay (40 seconds) on first jsp access

Hi,  On Windows 98, Tomcat 3.2.1  3.3M2 (they both show the delay)
Stand-alone...   I have some Servlets, that I include into some
pages like so:
...
h2Favorite Public Virtual Slides/h2
jsp:include page="servlet/GroupFavorites" flush="true" /
...

Q: Is there any better way to include the output from a servlet
in an otherwise static page?

The very first time I start Tomcat, and access this page, there
is a very very long delay.  Everything is running on localhost,
so I don't think there is any kind of name lookup that is timing
out...

If I turn on LogEvents in 3.3M2, I get the following:

...

The delay is _much_ longer than it would take to compile the jsp page,
and there is no hard drive activity during the time.

Does anyone have any idea what would be stalling at this point???

I believe that the bean can be handled the same way as the Servlet which mean
that you can use:

// Set the attribute and Forward to hello.jsp
request.setAttribute ("servletName", "servletToJsp");

getServletConfig().getServletContext().getRequestDispatcher("/jsp/jsptoserv/hell

Hi there.

I notice a few people have claimed to see high cpu utilisations when 
using tomcat on NT.  I have been using tomcat 3.2 on Solaris 7 (Ultra 
5).  The configuration is pretty much out of the box, except for turning 
on https support and changing default http port to 80.  The load on the 
machine is very light, and when the server is started CPU utilisation by 
the tomcat process is very low.

However, inevitably over the next few days, CPU utilisation climbs to 
close to 100% and does not diminish until the server is restarted.

Does anyone have any clues as to the probable cause of this?

Re: Use of JNI with Apache

Apache module in Java?  Do you mean a servlet/jsp in Tomcat?  I know that a
segmentation fault in JNI kills the JVM dead
so Tomcat will just disappear.   You should get messages in the shell Tomcat
ran in though and a javacore.

Subject: Tomcat 3.2 CPU utilisation


Hi there.

I notice a few people have claimed to see high cpu utilisations when 
using tomcat on NT.  I have been using tomcat 3.2 on Solaris 7 (Ultra 
5).  The configuration is pretty much out of the box, except for turning 
on https support and changing default http port to 80.  The load on the 
machine is very light, and when the server is started CPU utilisation by 
the tomcat process is very low.

However, inevitably over the next few days, CPU utilisation climbs to 
close to 100% and does not diminish until the server is restarted.

Does anyone have any clues as to the probable cause of this?

Different Apaches using same Tomcat ?

2001-03-22 Thread Wolf


Hallo,

I read a lot of documents but didn't found a solution.

Is there a way to let different apaches use the same tomcat-instance ?

We have to manage different apaches on the same machine (let's say: germany,
france, .. - one IP for each of them)
All of them must be able to serve JSP's and Servlets (using mod_jk) - all
the files are located at this single machine (linux) (sourcedir: web,
including subdirs: de, fr, ... - containing the files of the various
apaches).
The idea is to start a single tomcat instance running a loadbalancer which
will be used by each apache.

I've used the apache's mod_rewrite to difference between the different
JSP-dirs (let's say: //germany/JSP will become a //germany/de_JSP, ... For
these I defined contexts e.g: /de_JSP, /fr_JSP, ...
[ e.g. the germany will generate a //germany/de_JSP/hello.jsp (called as:
//germany/JSP/hello.jsp) and the france will generate:
//france/fr_JSP/hello.jsp (called as: //france/JSP/hello.jsp) ]

The tomcat runs a loadbalancer which will spread the incoming requests all
over the contexts.

Is this a "good" idea (resources), is this possible OR should I (have to)
create different tomcats (one for each apache) ?

Thanks,
Bernd.

getThumb().

2001-03-22 Thread Eric Jenson


If the file that has changed is actually an included file in the requested
page, the container will not know to recompile the jsp page.  You will need
to open the file in NT and resave the requested jsp page to prompt the
container to recompile.  In Unix you use the touch command.  Don't know if
that is your problem but thought I would put my two cents in.  Hope this
helps.

AW: Tomcat 3.2 CPU utilization

2001-03-22 Thread Stefan Busse



Donnie,

thank you for your hint. I have experienced similar problems with solaris 8 and
tomcat 3.2.1. However I regret that I do not understand the mentioned problem:

 6.11 Misconfiguration Can Cause CPU-Bound Loop

 If you misconfigure Tomcat 3.2 in a way that there is no valid context to
 handle a request (such as removing the root context and then attempting a
 request that should be handled by that context), Tomcat will enter a CPU-bound
 loop instead of responding with a 404 error.
 
 Workaround:  kill the offending Tomcat process and correct your server.xml
 file such that there is a properly configured root context.

Could anyone perhaps give an illustrative example ?

TIA

Deploying a JSP among servlets

2001-03-22 Thread Wolfgang Stein


Tomcat 3.2.1

1) Is it possible to put (and access directly) a JSP among servlets
located beneath WEB-INF/classes ?

2) Is it possible to package (and access directly) a JSP 
along with other classes located beneath WEB-INF/classes ?

or

3) Is JSP access generally restricted to directories
above WEB-INF ?


All my servlets inherit from a superclass that 
provides pooled connections, sophisticated logging and collects 
some statistical data (time of first servlet instantiation,
concurrent requests, duration of request handling etc.)

The superclass is contained in a package along with
a connection manager, a logger class etc.

I want to build an admin web interface for that superclass
(or the deriving servlets respectivly), providing output
of formatted statistics and dynamic adjustment of some values
(pool size, log level etc.).

I would like to implement that web interface using JSP technology
in a quick and dirty manner - which is sufficient for admin 
purposes  :-)


I struggled with web.xml for hours without success,
but I am a JSP newbie.

No. 
The way you are doing means you are calling .toURL() method on what ever is 
returned by the method getThumb(). Unless getThumb returns a type of Object of 
type SuperOne or it's sub-class you cannot call this method and you should see a 
compile time error.

What 
you can do is 

URL 
url = toURL( myImage.getThumb() ); in your SuperOne or its

you need Apache as your server through which Tomcat

System.out.println() and mystery error message

2001-03-22 Thread William Blackmon

Title: System.out.println() and mystery error message





I just started using Tomcat 3.2.1 and have 2 questions.
First of all, what do I set to view servlet and class output so I can debug my code? The same information
is going to the tomcat.log file that is showing in the Tomcat cmd window (I'm using Win2000). I have
my Logger name entries in the server.xml file set as follows:
Logger name=tc_log 
   verbosityLevel = DEBUG 
 /


 Logger name=servlet_log 
 path=logs/servlet.log
 verbosityLevel = DEBUG  /
 
 Logger name=JASPER_LOG 
  path=logs/jasper.log
 verbosityLevel = DEBUG /
Surely there must be a way to see the output of various files, otherwise how can you tell whats 
going on (sending it to html output is NOT an acceptable alternative)




Secondl, when I OPEN a mere html page in the browser that submits to a jsp, I get following error
message:
Ctx /bill: IOException in :R /bill + /register.html + null Connection aborted by peer:
socket write error.

Re: Java Question on Inheritance


Then this is my next problem.

I currently have getThumb() returning an Image object.

The part where I am stuck at is what to do in the toURL() method.

my mock getThumb() method currently looks something like
 public Image getThumb(){
  this.iValue = "/home/thumbs";
  return this;
 }

 I want  to be able to do this efficiently and use something like the
 following syntax.
 
 myImage.getThumb().toURL()
 
 
 Is this possible?

 Yes, but getThumb() must return a subclass of SuperOne.

Tomcat dies on OS X

2001-03-22 Thread sandeep parikh


I'm running tomcat 3.2.1. on Mac OS X Public Beta and after starting
tomcat up, it will suddenly die not respond...When I shut it down it
throws me some errors pertaining to the HttpConnectionHandler class.

When I try to startup again, it throws the same error.  If I change the
port number in server.xml and restart the whole problematic cycle starts
again.

I've narrowed down some specific behaviors like:
- when I start tomcat, I can access the main page at http://localhost:port
- context manager recognizes and sets the appropriate paths for my
  servlets and jsps
- when I try to access my servlets/jsps, tomcat suddenly does not respond
  and thats where the trouble starts...

if anyone has any insights or information about this behavior, pls let me
know...

To use a bean in JSP, thebean must belon to a package:

To whick package the generated servlet belongs is

mod_jk --- tomcat communication errors

2001-03-22 Thread Shahed Ali


Hi,

I have a Live Website running tomcat 3.2.1 on Solaris 8 / JDK 1.3 / mod_jk
and ajp13 and Apache 1.3.14

I have come across the following problems

1. Occasionaly, I get a 500 server error from apache and mod_jk.log has
socket timeout errors.

2. Today, the site just hung. When I made requests, mod_jk logged them,
but the requests were not reaching tomcat.

i.e tail -f mod_jk.log showed a request being sent, but tail -f
jasper.log did not have the
corrosponding jsp page show up.

Any idea what can be causing this problem ?

Every time this happens, I need to restart apache/tomcat.

Thanks
Shahed.

RE: Delay (40 seconds) on first jsp access

2001-03-22 Thread James Carroll



 The Psuedo-Random Number Generator (PRNG) used to create 
 session ids took
 several seconds to initalize on some platforms.  This caused a very
 noticable delay for the first request that created a session. 
  This has been
 changed in Tomcat 3.2.2.  The PRNG initialization is now 
 *much* faster and
 is also done when Tomcat starts instead of when the first session is
 created.

Has this change happened in 3.3M2  'cause my delay happens
there too.

RE: Delay (40 seconds) on first jsp access

2001-03-22 Thread James Carroll



Hi Alan,

 What initialisation is your servlet doing?? 

The servlet itself is attaching to MySQL, and doing a quick
query. 

If I access the servlet directly, (no jsp) there is _no_ delay
whatsoever.  The MySQL connection, query, formatting all take
less than a tenth of a second even on the very first access
after Tomcat has started.

I'm not creating any sessions yet, so the randomizing of the
session ID isn't the cause of the problem...

This is the last problem I have before I start doing some
deployment!  Now that I've spent the time to get to know Tomcat,
I'm loving it.

During Initialization:

- the Servlet checks the context for an existing Database Engine
and then (when it doesn't find one) instantiating one and 
adding it to the servlet context:

// make sure that the VSDBEngine is running
ServletContext context = getServletContext();
if (null == (itsEngine =
(VSDBEngine)context.getAttribute("vsdbEngine")))
{
itsEngine = new VSDBEngine(context);
context.setAttribute("vsdbEngine", itsEngine);
}

- It initializes a database Connection Pool, and a JDBC Table-oriented
helper class.

public VSDBEngine(ServletContext sc)
{
// necessary for logging
itsServletContext = sc;

log("-- ( r e ) l o a d  ");

// load a database driver that the driver manager
try
{
// The newInstance() call is a work around for some
// broken Java implementations
Class.forName("org.gjt.mm.mysql.Driver").newInstance();
}
catch (Exception e)
{
log("Unable to load driver.");
e.printStackTrace();
}

// should work with Tomcat... databaseURL is defined in the
web.xml file.
String dbURL =
config.getServletContext().getInitParameter("databaseURL");

// initialize the Connection Pool
String dbURL = (String)sc.getInitParameter("databaseURL");
itsConnectionPool = new VSDBPool(dbURL);
itsConnectionPool.sc = sc;

itsTableJDBC = new TableBasicJDBC();
itsTableJDBC.setContext(sc);
itsTableJDBC.setPool(itsConnectionPool);
}

- It does a query
// set content type and other response header fields first
statement = c.createStatement();

sql = "SELECT slideID FROM slide";
sql += " WHERE";
sql += " favorite='yes' ";

statement.execute(sql);
result = statement.getResultSet();

while (result.next())
{
ids.addElement(new Long(result.getLong("slideID")));
}

- then prints results.

Re: AW: Tomcat 3.2 CPU utilization

2001-03-22 Thread DONNIE HALE


Stefan,

Tomcat expects there to be some configuration for the "root" context - that is, any 
resource directly under "/". An example would be "/index.html". This is as opposed to 
an application context such as "/myapp/index.html".

The default install has a "ROOT.war" file. It seems that anything in that directory 
("ROOT" - all caps), if it exists under the webapps directory, will be used for 
anything requested in the root context. If that directory doesn't exist, ***and*** if 
no other directory has been explicity specified for the root context in server.xml, 
then you'll see this CPU spinup.

As an example, in our server.xml, we have specified the root context as:

Context path="/" docBase="web/nosuchdir" debug="0" reloadable="false" 
/Context

Since there is no relative directory named "web/nosuchdir", anything requested under 
"/" will return a "Not Found" error.

Hope that helps,

Donnie



 [EMAIL PROTECTED] 03/22/01 11:54AM 

Donnie,

thank you for your hint. I have experienced similar problems with solaris 8 and
tomcat 3.2.1. However I regret that I do not understand the mentioned problem:

 6.11 Misconfiguration Can Cause CPU-Bound Loop

 If you misconfigure Tomcat 3.2 in a way that there is no valid context to
 handle a request (such as removing the root context and then attempting a
 request that should be handled by that context), Tomcat will enter a CPU-bound
 loop instead of responding with a 404 error.
 
 Workaround:  kill the offending Tomcat process and correct your server.xml
 file such that there is a properly configured root context.

Could anyone perhaps give an illustrative example ?

TIA

I spent a full day and a half trying to track this down. Once I had figured out the

can peg a single CPU on a multi-CPU box just by requesting "/anyfile.html" from a 
browser. Your browser will just sit there for almost ever, and you'll see the CPU % 
jump way up. I'm just mentioning this so that you can prove quickly that your problem 
is solved.

Hi there.

I notice a few people have claimed to see high cpu utilisations when 
using tomcat on NT.  I have been using tomcat 3.2 on Solaris 7 (Ultra 
5).  The configuration is pretty much out of the box, except for turning 
on https support and changing default http port to 80.  The load on the 
machine is very light, and when the server is started CPU utilisation by 
the tomcat process is very low.

However, inevitably over the next few days, CPU utilisation climbs to 
close to 100% and does not diminish until the server is restarted.

Does anyone have any clues as to the probable cause of this?

RE: single login form for single sign on

On Thu, 22 Mar 2001 [EMAIL PROTECTED] wrote:

   and error page that will be used by all webapps?
   
  
  No.  Each web application is still a stand-alone entity.
  
  What single sign on support does for you is remember that 
  you've signed on
  already.  You are still using whatever login mechanism is 
  defined for each
  individual web app.  They don't even have to all use the same approach
  (some could be BASIC, some could be FORM, for example).
  
 
 What's the thinking behind this? Single sign on would imply having, at least
 the option of having a single login page, even if an individual web
 application could override the default and provide its own (for instance I
 guess webdav can't use FORM, so would have to override a FORM default to use
 BASIC/DIGEST).
 

The primary thinking behind this is to obey the servlet specification's
requirements :-).

The typical use case is a "portal" site (say, like Yahoo) where there are
a variety of applications that require you to log on before use, mixed in
with a ton of stuff that is available to everyone.  Each of the
applications has it's own individual look-and-feel (within the broad UI of
the entire site), and doesn't necessarily *want* to have to share a page.

Now, I can go browse around Yahoo to my heart's content.  As soon as I
access an app that needs a login, I'm asked to do so (within the context
of that app).  To avoid making me unhappy, the site remembers who I am so
that when I switch to a different application that needs login, I go
straight to what I asked for without having to identify myself again.

 Having to define login for each we application:
 1. provides a maintenance problem if you do want a common login page across
 all webapps

Seems like a simple problem to solve in your build scripts.  Copying
commonly used components from a single source repository is quite
straightforward.

 2. begins to enter into "using my password for something I haven't approved
 it to be used for" teritory. i.e. the login page says you are logging into
 webapp1, but in fact your login will be used for webapp2. A single login
 page would tell you you are logging into both.
 

So, all you have to do is say so on the login page, and this confusion
cannot happen, right?  If you follow the suggestion above and copy the
common login page to each app you will have certainly done this.

 Hence my initial question - is this just the way it has been done, or does
 the Spec say it must be done that way etc.?
 

http://java.sun.com/products/servlet/download.html

See the "Security" chapter in the Servlet 2.2 spec.  You will also want to
review the requirements on servlet contexts (i.e. web applications) and
sessions (scoped to a single web app) that affect application design for
environments like the one discussed above.

 Many thanks

Refresh Problem

2001-03-22 Thread Martin Mauri


Hi gurus!

I'm using Cocoon 1.8.2 over Solaris 2.7 with Apache1.3.19 - Tomcat - Mod_jk
When I run Cocoon in the standalone way over Windows ME, every modification
I do on the files is inmediately refreshed, but I can't do the same when I
run it in the way I said on the top or even in standalone! I cannot get the
changes refreshed!

Any suggestions?

thanks!

Yes, it absolutely does.

Network file systems often cache directory information about the files you
access, in order to avoid lots of network traffic.  Thus, a file can be
changed on the Samba server (with an updated timestamp), and the Samba
client (i.e. the machine Tomcat is running on) does not know that.

IMHO, running your webapps via a network file system (Windows shared
disks, Samba, Unix NFS, etc.) is not a good idea.  You'd be much better
off (and have much better performance) if you moved Tomcat to where the
files are located, rather than the other way around.

RE: Does JDK1.3 works with Tomcat?


You are correct. The problem I had was I didn't compile class into a
package. Now it works.

Thanks,

I'm missing the package definition in Counter.java.

To use a bean in JSP, thebean must belon to a package:

The statement
useBean id="myBean" class="Counter"/ ...
will look for a class named counter in the package of
the current class (which is the generated servlet).
To whick package the generated servlet belongs is
completely up to the jsp engine.

 Betreff: RE: Does JDK1.3 works with Tomcat?


 I didn't use special methods. the java codes are very simple
 and listed
 below:
 
 import java.io.Serializable;
 public class Counter implements Serializable{
 int count = 0;

 public Counter(){}

 public int getCount(){
 count++;
 return this.count;
 }

 public void setCount(int count){
 this.count = count;
 }
 }
 ---

 Here is the directory structure:

 web -- homepages -- jack -- counter.jsp
 web -- web-inf   -- classes -- counter.class

 The error message is:
 Class homepages.jack.Counter not found in type declaration.

 Please help
 Thanks,
 Jack Li

 JDK 1.3 does work with tomcat. Your bean must be using some
 specific jdk
 1.1.*
 methods that is not supported in jdk 1.3 (and most likely
 also jdk 1.2).
