RE: RMI and TC4.x

[David Oxley]

It does actually connect to the RMI server, but it can't download classes
from the web server. It looks like java.rmi.codebase = TC local path rather
than http://server/webapp which iks what the code sets it to.

Has anyone got RMI working from within TC4.x. I had no problems under TC3.x,
but just can't get it working under TC4.x.

I have had a bug report outstanding for quite some time on this, but I was
hoping that someone on the user list may have already got this working.

RE: Apache->Tomcat Howto?

[David Oxley]

As far as I know mod_jk should still be used for 4.1.x, not mod_jk2. When
people talk of Coyote JK2, they mean the Java side which is enabled by
default when you download TC4.1.x.

RE: SV: How to start/stop tomcat from a remote machine???

[David Oxley]

The new jk_nt_service.exe (TC3.3) already has this facility build in. You
might need to get it from CVS because I can't remember if it is in beta2.
Also if you look in bugzilla there is a Service Manager (like the SQLServer
one) that I have contributed. Just download and build (You'll need to patch
jk_nt_service as well).

TC3.3 Auto Config

[David Oxley]

Hi all,

This isn't an urgent problem as I can manually change mod_jk.conf.

I am trying to get TC3.3 to auto configure itself (startup.bat -jkconf), but
it configures mod_jk.conf for serving static content from TC3.3. I read that
it was supposed to pick this up from web.xml. So:
1. Either my web.xml is wrong. How is it wrong?


StaffplannerController


StaffPlannerControllerServlet





StaffplannerController


/servlet/StaffPlannerControllerServlet



2. Tomcat 3.3 is supposed to do this.
3. There is a bug.

Hi David,

Multiple virtual hosts on IIS is something I have not found time
to try to do, yet.  However, it is something I hope to support
in Tomcat 3.3.

Tim Whittington has submitted a patch to the isapi_redirect.dll
that should be included soon.  It adds a feature where
the "isapi_redirect" dll queries its actual file name and
uses that name to read a ".properties" file from
the same directory.  If that file exists, those properties are
used.  If not, it reverts to the old behavior of getting the
"properties" file location from the registry.  This "properties"
file would specify where to get the "uriworkermap" file.

This implies that you get multiple isapi_redirector instances,
each using different settings, by having multiple copies of the
"isapi_redirector" with different names.  Each virtual host
would use the appropriately named copy.  Not elegant, but
I'm not sure there is a better way.

Cheers,
Larry

IIS Virtual hosting

[David Oxley]

Hi all,

I need to set up IIS with each virtual host routing to a different worker in
Tomcat. Each virtual host has the same web application under it and
therefore must all be the same context.

i.e. Under Apache I set up the following:
NameVirtualHost 128.100.2.23


ServerName cisweb2k
JkMount /spweb/servlet/* ajp13_1



ServerName cisweb2k2
JkMount /spweb/servlet/* ajp13_2


How is the best way to achieve the same configuration with IIS?
I think what I need is to be able to specify the host name in
uriworkermap.properties:
cisweb2k/spweb/servlet/*=ajp13_1
cisweb2k2/spweb/servlet/*=ajp13_2

Thanks.
Dave.

You should probably remove the space after the .dll in your registry. That's
what would cause the +.

Subject: Win2K isapi_redirect.dll+ 404, jk_ajp12_worker.c never called

I've followed
 to
the letter, triple-checked each step, rebooted twice, and still get 404s on
localhost:80. Here are the symptoms:

-  works, as do the servlets
- green arrow on the jakarta filter, which I've added to Default Web Site
- jakarta virtual directory is present with execute permission for scripts
  and executables
- request for  is 404
- IIS log shows a rather curious "+" sign after the DLL name and 404
  result. The only instances that I can find on the Web of the plus sign
  in IIS logs relate to others who have had this problem, none of whom
  report a solution.
- tomcat-isapi.log indicates that jk_isapi_plugin.c HttpFilterProc is
  parsing the path "should redirect to ajp12"
- jk_ajp12_worker.c is never called in isapi_redirect.dll (so Tomcat never
  gets the task).

TIA for any suggestions.

I have a slight problem and need some help, I have trawled the lists and
havent found my answer yet...

I have set up tomcat to run as an nt service using jk_nt_service, which
works well, as in it starts the service for me. But I am still getting a
problem, when i try to run serlvets, it keeps coming back with a db error,
saying that that it couldnt get a connection..

If I stop the service and start tomcat using 'startup' instead, my serlvets
run perfectlycan anyone point me to the answer to my problem?

Cookies and IE5.5

[David Oxley]

I am trying to set a cookie that can be picked up from a different server to
the one setting it. They both belong to the same domain (daves.domain.com
and daves2.domain.com). 
The first server sets the cookie and redirects to the second server where
the cookie is read.
On IE5.5 and above the cookie does not get set, but it works fine for IE5
and Mozilla.
Is this a bug with later versions of IE or am I doing something wrong.
This is the code:
Cookie c = new Cookie("User", "DAVE");
c.setDomain("domain.com");
c.setPath("/servlet/LogonServlet");
c.setMaxAge(60);
c.setVersion(1);
resp.addCookie(c);
resp.sendRedirect (redirect_url) ;

So, just to clarify:

The request arrives, Tomcat processes it and sends it to your servlet.
You do:
response.setContentType("text/html");
// commits the response
response.flushBuffer();
and, while your servlet thinks what it must send next, the browser
resends the response.

Is this the case? What browser is it? Mine (Netscape Communicator 4.7)
does not.

RE: Multiple requests

This isn't the problem. Tomcat is calling my servlet, but because the
machine is so busy it is taking a long time to construct the response, and
hence the request is resubmitted before it has sent back the response. I
need a way to tell the browser that the server has received the request and

All the examples and archive messages that I have seen so far talk about
load balancing
using either multiple JVM's or Multiple  Directives with
different port numbers
and corrosponding workers in the workers.properties file.

But they all use different Mount Points for each worker !

However my need is to Load Balance a *SINGLE MOUNT POINT*
( A single Virtual Apache Host corrosponding to a  (context) in
server.xml )

i.e I want http://ww.mysite.com/*.jsp to be load balanced by 4 worker
threads.

I am currently using 4 JkMount Directives, and the server is up and running.
i.e
JkMount /*.jsp ajp13
JkMount /*.jsp Xajp13
JkMount /*.jsp Yajp13
JkMount /*.jsp Zajp13

Also if I name the workers ajp13a , ajp13b and ajp13c, apache does not start
and gives me an error
saying that it cannot find the workers file !!!

Anyway, my question are :-

1. Is this the right way to have a single mount point load balanced ?
2. If so, is it a good idea to run the tomcat instances in the same JVM ? Or
should I run multiple tomcat/JVM
instances on the same / different servers ?

You could try having the JSP set its modified time to 'now', using a
java.util.Calendar object. That should cause the cache on the browser to
retrieve an updated copy of the page. I don't recall how to do this in
JSP land, but servlets do it by implementing getLastModified(), derived
from HttpServlet. The idea is to set a header in the response object to
indicate the modification time as being a few milliseconds ago, but
I don't recall the exact name of the header that needs to be set.

Sorry I couldn't be more helpful.

RE: Upcoming Tomcat book...

[David Oxley]

A couple of things I would like to see in a book (and seems to have never
been covered before):

1. How to structure large servlet applications (Data model).
2. Scalable/fail safe servlet applications.

i.e. Our application is accessing a database of up to 100Gb and we cache all
of our data in the memory of the VM rather than reading the DB for every
request. The VM can only handle 2Gb, but in reality should hold 500Mb or
less. The data model is very complex and is very sophisticated. We have
features such as lazy writing where it updates the record in memory, but
doesn't send the changes to the database immediately; early reading where we
do a big SQL select in replacement of lots of small SQL selects and cache
the result set until ready to build our internal data model.

We are less concerned with performance in our application because the real
limit is the amount of memory the VM is currently using (50 users are likely
to be using 250Mb), therefore concurrent users aren't going to cause a large
amount of performance issues, but could potentially cause memory problems.

As the data is loaded in several separate VM's fail safety became a problem,
but has been sufficiently resolved for our app. Also data that needs to be
shared between instances of the VM is very difficult. We have had to
broadcast to the other VM's that a particaular record is now invalid and the
next time it is used it goes back to the DB.

We have had consultancy from IBM on these issues and we wanted to find
another company and books to help us as well, but we have failed so far. By
the way if anyone knows of a consultancy company that has had experience of
projects like this please forward their details to me.

If you want to discuss the issues we have resolved and how we have done it;
or discuss the issues that still remain EMail me.

SSL response

[David Oxley]

I tried posting this question on Sunday, but got no response so here it is
again:

I am using Flash to make a https request to a servlet. Flash seems to send
the request and it gets to the servlet, but it hangs when reading/getting
the response. It works fine when getting a text file containing the same
info over https. Therefore two questions:

1. This is how I create the response:
resp.setContentType("text/plain");
resp.setHeader("Cache-Control", "no-cache");
out = resp.getWriter();
Is this correct? Am I missing something? Should the mime type be different?
Do I need to set the response size? etc.

2. Is there a program to snoop on the http response so I can tell the
difference between the reponse from the servet and from the text file?

This is really urgent, so if people aren't responding cause I've done
something so stupid they can't be bothered, please repond anyway!?!?

The http // https comparison doesn't work as cookies are sent or not
depending on the host, not on the protocol.

So if I have a valid session_id in a cookie in http, that will still be sent
when I switch to https.

So I can either have a common pool of current cookies if my https server is
seperate from my http server (seems a hard way to do it) or I just access
the software (eg Tomcat) via a webserver (eg apache) through either protocol
and the session continues without complaint.

Unless I did something complicated without noticing, of course...

What I've seen done, which doesn't necessarily make it secure, it to
send some form of CartID.  This ID identifies the Cart in some shared back
end data store.  Usually these are large numbers that contain enough
information to determine if its a possible real value, or a number someone
made up.  If its something that someone made up, usually their IP is locked
out for a certain amount of time or a session field is set that doesn't
allow them in as long as that same session is valid.

Like URL-Encoded session management. The host passes our session id back to
the server when changing hosts so that it can be connected to the new
HttpSession.

Doesn't normal session management have exactly the same problem. When
writing an E-Commerce system the basket is normally chosen on an unsecure

HttpSession across virtual hosts

[David Oxley]

Hi all,

I know that the HttpSession is only valid on the virtual host it was created
on. This is more of a security question. We currently have our own session
class that gets stored in an HttpSession 1:1 ratio. So we've coded a request
that allows us to GetSessionID on the original host and then AttachSession
on the new host. Which basically does a lookup of the session id in a static
hashtable to find one of our sessions and then attaches it to the new
HttpSession. This is used when switching from a non-secure to and from
secure host. My question is while the user name and password goes to the
secure host the session id will be sent on the unsecure host in the
AttachSession request:

1. Can this be intercepted by a hacker and used as if they had logged on?
2. If I save the remote ip address and check it during the AttachSession, is
that secure enough or can some hacker pretend to be the same ip address?
3. I am right in assuming there is no way of making an HttpSession valid
across virtual hosts (Make my life a lot easier)?
4. How can I keep the HttpSession on the original host valid? Or is it
easier to do an AttachSession every time the host is switched?

Thanks.

RE: Which JVM for Tomcat?

[David Oxley]

Right.

1. First of all You can write a java applet that uses java1.1 i.e. the VM
included with netscape and IE so the user doesn't have to download anything.
And you can still use 1.3 on the server. You don't need to install another
vm on the server.

2. Can you please stop flaming each other. There are people of varying
degrees of knowledge that use this list. If you flame in a discussion the
experts won't read on and you won't get any help. Rather than call people
thick answer the question in a quick way that will allow them to understand
or don't!! If someone does call you thick, this just does not dignify a
response.

3. I wouldn't mind knowing which JVM is fastest on Linux. What is Blackdown
(I think that's what its called) like. Is it faster than Suns?

In your command prompt. cd into %TOMCAT_HOME%\bin and type 'tomcat run'.

Ant1.2 has a War file tool from your ant build script that is really useful.

Betreff: tomcat vs orion vs weblogic testing results (Load Runner)

Hi all..

I'm doing work load testing on a webapplication built on javascript, .JSP:s
and EJB:s. We've load tested on many different setups and are getting some
interesting results:

Simulated number of users: 25
Computer setup: NT4 sp6, 1 GB RAM, Pentium III ~600 MHz
Tomcat setup: 1 ajp12-worker.. (We need out-of-process workers for
scalability)


setup1: webserver - apache 1.3.x, jsp - tomcat 3.2b6 (mod_jk.dll)
setup2: webserver - weblogic, jsp - weblogic (latest versions as of this
date)
setup3: webserver - orion, jsp - orion (latest versions as of this date)


setup2 and setup3 are 8 (eight) times faster in our tests (Load Runner).
Even if we suspected tomcat to be a bit slower, this is truly remarkable..
We've tried optimizing Tomcat by:
1. using ajp13 protocol - failed, we're just getting exceptions from tomcat
2. reloadable=false - of course
3. fiddling with JVM memory settings - minor improvements

Any ideas on what's wrong here? This must be a configuration problem. Have
anyone else found the same results?

Running batch files when using as a NT service

[David Oxley]

Are there any issues with running batch files that call external programs
when Tomcat is set up as an NT service. 
I have a problem that when using the startup.bat my COBOL routine gets
kicked off fine, but when Tomcat is a service the COBOL returns an error
code and never executes. I have a feeling its to do with environment
variables and I am still investigating, but I thought I would just ask if
there were any issues with doing this.

RE: design for a database pool and applets

[David Oxley]

An idea is to set up you servlet as an RMI server and make requests to your
servlet from your applet. Bear in mind that you should design your app in a
multi-tier way. i.e. Your database access, business logic and UI code should
all be seperate. Applets are normally classed as UI and should therefore not
access the DB themselves!

RE: workers - loadbalancing

[David Oxley]

I haven't yet got round to trying this but

I believe the worker.ajp13.lbfactor parameter is only the priority of this
worker (not the number of processes). You must start your own processes
seperatley as in virtual hosting and set up your
worker.loadbalancer.balanced_workers to point at the various workers you
have set up. You must then swap your config in mod_jk.conf from using ajp13
or ajp12 to use lb.

i.e. Something like this:

worker.ajp13_1.port=8009
worker.ajp13_1.host=localhost
worker.ajp13_1.type=ajp13
worker.ajp13_1.lbfactor=3

worker.ajp13_2.port=8009
worker.ajp13_2.host=otherserver
worker.ajp13_2.type=ajp13
worker.ajp13_2.lbfactor=12

worker.ajp13_3.port=8011
worker.ajp13_3.host=localhost
worker.ajp13_3.type=ajp13
worker.ajp13_3.lbfactor=3

worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=ajp13_1, ajp13_2, ajp13_3

The better the machine (or less busy) set the lbfactor for each worker
higher.

Subject: workers - loadbalancing


Hi,

I am currently working on a virtual hosting solution for JSPs / Java
Servlets for my company
fyi: i am using redhat 6.2, tomcat 3.2 beta6 (eagerly awaiting the final
3.2) and the SUN JDK 1.2.2 as the platform for all of this

i am doing all fine configuring virtual hosts and i think i have
(almost) all security issues covered;

the one thing that confuses me about tomcat and / or the JDK i use is
the following:

isn't tomcat supposed to spawn more than one process when configuring
the 
worker.ajp13.lbfactor=10 for example ? or did i misunderstand the
(rather scarce :-) documentation ?
somehow i think that this depends on the JDK that is used:
in the beginning, when i was still experimenting with (apache)jserv and
different java servlets, i used blackdown's jdk 1.2.2, and every time i
restarted apache and therefore the servlet engine / container, at least
4 or more java processes were spawned
but using the same configuration and instead of JDK from blackdown using
SUN's java development kit, only one! process was spawned from the
start! - the same now with tomcat (although i havent tried it with any
other JDK than SUN's yet, i must admit)

Or did i misunderstand the whole issue, and the loadbalancing is done in
some other way ?

I hope someone can shed some light on this!

Hi,

as you must seen, there was some discussion about how to detect the closing

a session lately. You can follow the same idea and create a static object
that

sessions that are created. It can have a internal variable which stores the
number of sessions open.

If your talking about the %TOMCAT_HOME%\conf\web.xml, then no it is not
defined in there. It is also not defined in %TOMCAT_HOME%\conf\server.xml.
All I have is the context\WEB-INF\web.xml which I have attached.
I have done some further tests and I actually have a new object of my
servlet class. So it is calling init in one instance of the class and then
creating a new instance of the class and calling init again when the first
request is made. It makes no further calls to init after this.
Also the init method is completing succesfully with no exceptions.

On a side point what does the number in the  tag in web.xml
mean.

[David Oxley]

I have just tried this and it causes my app to stop working.
Does this now mean that I need to put the context into
%TOMCAT_HOME%\conf\web.xml, because this is a bit of a pain.

I had this.

In my case, it was caused by setting my context to be the root context.

I solved it by removing the

 

line from server.xml, so that only contexts explicitly defined in web.xml 
were loaded.

RE: Locating property files

[David Oxley]

What we do (and we would prefer a better solution) is copy it under
WEB-INF\classes directory. It would need to be in the .jar file if you were
to put it in the WEB-INF\lib directory.

Subject: Locating property files


My servlet requires access to a properties file and I'm trying to
determine the best implementation.   I tried copying the properties file
to the Webapps\"ContextRoot"\Web-Inf\lib directory, but Tomcat could not
locate the file.  I had to add the properties file to the classpath
within TOMCAT.BAT to enable Tomcat to locate the properties file.  Is
this my only solution?

Thanks in advance for your help,
Gary

RE: init being called twice

[David Oxley]

If your talking about the %TOMCAT_HOME%\conf\web.xml, then no it is not
defined in there. It is also not defined in %TOMCAT_HOME%\conf\server.xml.
All I have is the context\WEB-INF\web.xml which I have attached.
I have done some further tests and I actually have a new object of my
servlet class. So it is calling init in one instance of the class and then
creating a new instance of the class and calling init again when the first
request is made. It makes no further calls to init after this.
Also the init method is completing succesfully with no exceptions.

On a side point what does the number in the  tag in web.xml
mean.

Seems to me I recall that being traced to having a servlet entry in
both the base web.xml and application context web.xml.

init being called twice

[David Oxley]

Does anyone know why the init method is being called twice. I'm using
tomcat3.2b6 with IIS5 on W2K linked with isapi_redirect.dll. I have also
seen this with 3.1 with apache 1.3.12 on Solaris 7 linked with mod_jserv.so.

I can code around this so that the second time through it doesn't call my
init stuff again, but surely this is a bug?!

Any comments?

Try the tomcat-dev mailing list. Someone will probably take it off your
hands.

Hi

I made modifications on 2 files of the distribution "jk_util.c" and
"jk_jni_worker.c" to make mod_jk working on Mac OS X.
How can I submit theses modifications to the team developpers.

RE: SSL help..

[David Oxley]

On this question:
Am I right in thinking that you only need to do special SSL config in tomcat
when not connected to a webserver (i.e. port 8080).

Read server.xml in the conf/ directory.  It explains how to do it.
