Yes, tomcat gives a lot of messages like this :
512488 [Thread-73] INFO common.ChannelSocket  - server has been restarted or reset 
this connection

And it returns to work for some time again.
Apparently tomcat or mod_jk does not close the connection after serving the request.

MM> If you can't see any difference between the two configurations, do you think

I'm checked better, and the difference is :

Case when works (USING 2 MACHINES):
   RedHat 8, Apache 2.0.40 
   RedHat 7.3 Tomcat 4.1.18 

Case when I have problems
   RedHat 8, Apache 2.0.40 Tomcat 4.1.18 (SAME MACHINE)

The 2 use the same SUN SDK 1.4.1-01


But I have tried  today many combinations in the single machine :
SUNSDK 1.4.1, IBM SDK 1.3, 1.3.1, 1.4.
Apache 2.0.40 and 2.0.43
Tomcat 4.1.18 and 4.1.24

All configurations have the same problem.

All machines have up to date , kernels from redhat. And all other updates.

Last week I have made some tests with mod_jk2 with same problem.

The best way to do what you propose is have your Servlets upload the data
and then place a request for the further processing into a queue. At that
point you return to client saying "Processing you request, come back
later..." or some such thing. It obviously depends on whether the client
actually cares about the outcome or not.

Then on the other end of the queue is a process taking requests, performing
further processing on them and perhaps updating the status of the overall
job (so it can report it back to the client if they ask for it).

There are several ways you can do this kind of thing.

One, is to have the queue be a simple container (like an ArrayList) that has
it's overall access guarded by synchronized methods. This queue live within
the JVM, and another thread can be running endlessly querying the queue for
requests, and then acting upon them.

Another technique is to have the queue implemented within a database, and
then a completely seperate process, written in anything that can access the
database, can get access to the jobs and process them.

The Java Way of doing this kind of the is with JMS, which allows you to
abstact the whole queuing and monitoring aspects of the system. Here you
have a Publisher, which creates requests, and Subscribers, which act upon
then. Depending on the JMS system, these can all be within the same JVM, or
on completely different machines. It also makes it easy to have several
Subscribers acting upon the same Topic. A contrived example would be that
you have your Servlet acting as a Publisher, adding request as fast as your
users can submit them. Then, since your processing is CPU intensive, you set
up 10 different machines, each having the bandwidth to process 3 different
requests simultaneously. So, each machine creates 3 Subscribers, and you end
up with 30 Subscribers total.

The JMS system is fine way to pull things like this off, and the various
implementations have assorted features that differ on robustness,
scalability and performance.

However, if it were me, I'd probably roll my own simple queue and fire off a
couple of processing threads within the JVM of the Servlet container, have a
Servlet that initializes this whole thing loaded-at-startup within the
web.xml and be done with it. Make sure you persist the requests that have
not been processed yet so should the Servlet container quit, you can reload
and process those requests later after restart.

Like I said, JMS does exactly what you want, but if your needs are fairly
limited, writing your own is not overly complicated. A simple queue, a few
threads, a little DB work.

http://openjms.sourceforge.net/ is a free implementation, though I have not
used it.

Authentication with Tomcat/Apache Question

[Mete Kural]

Hi,

I am perplexed at this interesting problem. We want to use JDBCRealm to authenticate 
users in Tomcat, but yet we want to serve static stuff via Apache to improve 
performance. If we set up Tomcat as a worker for Apache using the JK2 connector, I 
don't see how requests for static files are going to be authenticated via JDBCRealm, 
since Tomcat doesn't even know about these static requests in the first place due to 
the fact that Apache handles them right away without dispatching them to Tomcat. I'm 
thinking that if we could somehow set up Apache to be a worker for Tomcat, and Tomcat 
received all requests and dispatched those that are static to Apache, then all 
requests would be authenticated via JDBCRealm. But I don't know how to do that neither 
if this is possible at all. Do you have any ideas on how to authenticate "every 
request" with JDBCRealm yet serve only static stuff with Apache.

Thanks,
Mete

RE: Custom JDBCRealm

[Raible, Matt]

I mean to say - the "type" of realm is irrelevant.  I've tested this
strategy using a JNDIRealm with LDAP, a MemoryRealm with tomcat-users.xml, a
JDBCRealm with MySQL/Oracle, and even a JAASRealm that talks to NT - works
fine with all and should be portable to other appservers.  If you extend a
Tomcat class and create your own authenticator - you'll have to add tomcat
jars to your project.

HTH,

Matt

RE: Custom JDBCRealm

[Raible, Matt]

Nope, I just use form-based authentication - the realm is irrelevant.  I
call request.getRemoteUser() to get the user's information and then look it
up in a database (could be ldap).  Tomcat does the authorization for me.

HOT redeploy of webapps using Tomcat 4.1.18?

[Johannes Fiala]

Hi there,

Has anybody done a hot redeploy of a web application context using Tomcat?

What I've got to work so far:
*) simply overwrite JARs in the /webapps/myapp/WEB-INF/lib directory and 
reloading the application context runs ok
*) however, if you really want to completeley redeploy a web application, 
I currently have not found any other solution than having to stop and 
start the application (which means putting the whole application down).

==> Is there really no way for simply exchanging a webapp during runtime?
What about the most simple solution: 
1.) putting up a new version (e.g. myapp2)
2.) using a redirect to redirect from myapp -> myapp2 (without the user 
noticing it)

this would also make it easy to step back if troubles occur.
any thoughts on this matter?

Johannes

Re: Custom JDBCRealm

may be this is dumb question. So do you run two filters? one for authticate and
to check authorization and other to load the customo objects??

Thanks Matt..

// user authenticated, empty user object
if ((username != null) && (userForm == null)) {
ses = getSession();

UserManager mgr =

ctx.getAttribute(Constants.DAO_TYPE));
UserForm user = mgr.getUser(ses, username);
session.setAttribute(Constants.USER_KEY, user);

Re: Custom JDBCRealm

[Carl Maib]

i am attempting the exact same thing, but have been advised it would be
better to override the FormAuthenticator. this gives you direct access to
the session.

the solution seems perfect, however, i i can't seem to get past
classNotFound exceptions. i am not familiar with how to link catalina
classes and the Class Loader docs are not giving me the answer.

i have configured server.xml to contain my custom valve, the class which
overrides FormAuthenticator. i have placed this class in common/classes. i
get class not found exceptions on FormAuthenticator bcz my webapp is not

RE: Custom JDBCRealm

[Raible, Matt]

Why not just add a filter that has the same  as your protected
resource.  I do this, and if there's not a user object in the session, I
populate it from a database.

Example at http://tinyurl.com/7xb1

RE: [OT] Servlet process issue

[Tam, Michael]

Hi Eric,

I do understand the Servlet is a request based ( new request -> new thread )
and how to avoid this with session attribute .. etc.

However, my concern was under the same request, if a client make a request
to (A), which passes to(B) and (B) passes to (C) and so on, then a client
could terminate the process by quitting the browser or "stop" the browser am
I correct?  If so, my question would be how to avoid the client to interfere
the process after (A) is completed [If (A) is terminate before it is
complete, then the entire process should terminate and it is ok]?

Regards,
Michael

A servlet is a highly specialized kind of object that is specifically 
designed to receive, process, and respond to requests.  In the case of 
HttpServlets, this would be HTTP requests.

It seems that unless your ValidationServlet and LoadServlet are ever 
going to be directly accessed with HTTP requests, they're probably 
better off being written as regular Java classes (like Validator and 
Loader).  I do not know anything about the overhead incurred by making 
them servlets, but it just seems that by subclassing HttpServlet for 
these objects, at least for the use case you've described, you're 
inheriting a lot more functionality than you'd ever need.

This will also simplify the design question you're asking -- you don't 
have to "backtrack" anywhere, your UploadServlet can just do whatever it 
is you want to be done when the request processing is finished (dispatch 
to a JSP saying "thank you"?).

Note that when your HTTP request is sent to UploadServlet, UploadServlet 
/is/ a new thread, so the user should not be able to interfere with this 
process.  If the user tries clicking "Submit" again, a totally new 
UploadServlet will respond.  If you wish to disable this ability, there 
is a technique involving the setting of a flag in the user's session 
that prevents any further requests being received until the processing 
is done.  But you have to implement this yourself.  The whole technique 
is detailed at 



HTH,

Erik

RE: tomcat responds with localhost, but refuses the connection w/ mach inename

Ahhh, found that I wasn't completely starting, it was hanging looking for
the keystore file, which had the wrong path, so shutting down was not
happening, cause it was not up and listening on that port yet.

Tomcat's Admin servlet

[Jake Robb]

Tomcat's admin servlet is in my way.  I have my own servlet called admin,
which I would like accessible using http://hostname/admin/.

So I went to $CATALINA_HOME/server/webapps and renamed the "admin" directory
to "tomcatadmin", stopped and started Tomcat, and then tried to navigate to
/tomcatadmin/.  I got a 404 error from Tomcat, with the message "The
requested resource (/tomcatadmin/) is not available."

I examined server.xml, $CATALINA_HOME/conf/web.xml, and
tomcatadmin/WEB-INF/web.xml, and I can find nothing that I think might be
the source of the problem.

What do I need to do to make the default admin servlet show up when I go to
http://hostname/tomcatadmin/?

Thanks,

Jake Robb

Custom JDBCRealm

[awc]

Hi,

I want to add more stuff to user session while user logs in. The only
way I see to do this is to write custom JDBCRealm class which extnds
org.apache.catalina.realm.JDBCRealm or implement
org.apache.catalina.realm.RealmBase class.

This custom class will have more initializing parameters too. Any
thoughts on this from one who already did sort of thing??

I am going to use this one with securityFilere from
www.securityfilter.org.

Thank you in advance for any replies.

new sample "best practice" Struts data driven web app for Tomcat5/Resin 3

[Vic Cekvenich]

I released a new basicPortal implementation called "bP v0.8k" available 
for download on basicPortal.sf.net.

- The new version is same simple "bean has a dao helper design", but it 
uses ibatis.com db layer. (the "older" design used RowSet) Ibatis db 
layer is very nice.

- It now works fine and is tested with MYSQL. (and pgSQL)

- It is build for JSP 2.0 containers, like a late build of resin 3 and 
tomcat 5, tested to work with both (but could be converted to JSP 1.2 
with addition of the c tag)

- It now has a list of maps backed beans for more flexibility. (old 
design was rows of columns), aka list backed bean.

- It uses display tag (struts menu, JSP2, JSTL, tiles, etc.)

- Like before, the base action dispatches, DAO is a interface (so you do 
not have to use iBatis db layer) and beans knows how to CRUD, via very 
nice OO.

Of course... still more to do

Re: no Tomcat process & error stopping service (Red Hat 8.0)

For reference, you can download the binary package of tomcat 4.1.18 and 
expand it to some other location.  You don't have to start it up or 
anything, but the binary version is "unadulterated" and will show you how 
the full dir structure should be laid out, including ROOT and the others.

networking mismatch between the dns name, and the real ip address are
completely different.  Using the machinename was having dns point me to a
box that was not mine, so of course the connection was refused.  Thanks for
the help though.

That's one way.  It pretty much comes down to how you want to handle 
Contexts.  If you want a particular Context to be available for a 
particular domain/host and that domain/host only, you would use a separate 
Host container.

Re: Connection drops with tomcat-based game server (very long version)

[Wouter Bijlsma]

Hi Justin,

First of all, thanks for your reply. Some of the problems you describe look an awful 
lot like the ones we're experiencing:

This is exactly what happens in our application. At first we'd get response times up 
to ~19000ms (yes, 19 seconds) when more than 10 users were logged in, but this was 
because the number of simultaneous threads per servlet was still at the default value 
(75). After bumping this number up to 1000 (which might very well be the source of a 
lot of other performance problems, but it's the only thing we could do to ensure 
reasonable performance for up to ~100 users) the response times stayed under ~1000ms. 
We already set up Tomcat as a standalone server because response times were *a lot* 
better without Apache.

This is probably what happens in the client, resulting in the message polling thread 
to crash/deadlock/block/stop or something like that.

We debugged both client and server extensively, but we too could not locate a 
consistent cause of problems. I do have to note that the game client already IS an 
applet, and that we weren't using the HTTP protocol in the first place. I don't know 
if tomcat makes an HTTP request anyways, but we don't tell it to, we are only 
reading/writing data to the InputStream's/OutputStream's we got from the URLConnection 
(client side) and the ServletRequest (server side).

Does this mean you don't have lost connection at all anymore?

A servlet is a highly specialized kind of object that is specifically 
designed to receive, process, and respond to requests.  In the case of 
HttpServlets, this would be HTTP requests.

It seems that unless your ValidationServlet and LoadServlet are ever 
going to be directly accessed with HTTP requests, they're probably 
better off being written as regular Java classes (like Validator and 
Loader).  I do not know anything about the overhead incurred by making 
them servlets, but it just seems that by subclassing HttpServlet for 
these objects, at least for the use case you've described, you're 
inheriting a lot more functionality than you'd ever need.

This will also simplify the design question you're asking -- you don't 
have to "backtrack" anywhere, your UploadServlet can just do whatever it 
is you want to be done when the request processing is finished (dispatch 
to a JSP saying "thank you"?).

Note that when your HTTP request is sent to UploadServlet, UploadServlet 
/is/ a new thread, so the user should not be able to interfere with this 
process.  If the user tries clicking "Submit" again, a totally new 
UploadServlet will respond.  If you wish to disable this ability, there 
is a technique involving the setting of a flag in the user's session 
that prevents any further requests being received until the processing 
is done.  But you have to implement this yourself.  The whole technique 
is detailed at

I think the root context is disabled by default in server.xml.  Open it
up and
uncomment the context entry for root, and for /examples if you want.

Re: Connection drops with tomcat-based game server (very long version)

[Justin Ruthenbeck]

Hi Wouter,

I can't give you concrete responses to your questions, but I can offer some 
anectodal observations from experience.

We also have a connection-sensitive, high message frequency, small message 
size portion of our application.  During bursts, the system must send and 
receive data as quickly as possible (every ~80ms or so) between the client 
(a browser) and the app server (Tomcat).

The application in general is a standard browser/server web based 
application and uses standard J2EE Servlet components.  We originally tried 
to do the same thing for the messaging component, but ran into excessive 
overhead and connection maintenance issues as well.  Specifically, we saw 
clients who occasionally had to wait long periods for their responses 
(~1000ms) or simply never received them.  Performance was better if we 
connected directly to the appserver instead of through IIS or Apache, but 
we still saw occasional connection loss.

These losses really killed the user experience and sometimes caused clients 
to ultimately mangle their internal state.  I would add that we saw similar 
problems with Weblogic.

After quite a bit of debugging, we were unable to determine a consistent 
cause of these problems, though it looked as though the appserver always 
responded if a valid Http request got to them.  This left us with the 
browser and network as potential offenders.  Fortunately, we had the option 
of applets.

We finally decided that relying on the browser and it's http stack to 
maintain connection was simply too risky and difficult to recover from.  We 
wrote our own lightweight mini Http client (as part of a client-side 
applet) and accompanying server (as an HttpServlet) running within our 
webapp on Tomcat.  With the finer grained control, error detection and 
recovery is much easier and we haven't been losing connections like before 
since the mini-http client has full control of when and why connections are 
closed.  Our request/response turnaround times are in the 20ms range for 
local networks.

This isn't to say such a solution would be best for you.  Implementing your 
own http client is a ripe field for frustration.  It also seems pointless 
to "reinvent" the http wheel when so many stable implementations exist.  In 
our case, however, it's given us the predictability we need while still 
allowing flexibility such as support for firewalled users and http proxy 
(or not) configurations.

Don't know how much that helps, but it's always good to hear of others' 
experiences.

Hi,

I'm currently co-developing a game (draughts, see www.damserver.nl) server 
that utilises Tomcat for message passing and relaying, which is in a 
testing phase right now. During development of the server (on a fast 
network) we encountered no big problems with Tomcat, but since testing has 
intensified somewhat (especially by testers on slow modem connections) it 
sometimes seems like Tomcat drops connections to clients randomly every 
now and then.

In short, the server works a bit like a chat server, with the exception 
that not only chat messages are relayed by it, but also moves, connection 
state information, user actions etc. The server keeps no internal state 
about board setups etc. (this is all handled by the clients), but only 
which users are logged in, where these users are at any moment (portal, 
room, table screen), and what games are being played by which users. 
Clients communicate with the servlet engine through only 1 servlet (this 
is because the servlet specs advise against sharing state information 
between servlets), which acts like a 'proxy' between the network and the 
server logic. We don't use the HTTP protocol (ie: we dont use HttpServlet 
but GenericServlet), but we do use the HTTP port.

Messages are encoded and sent (by 'requesting' the game server servlet) as 
raw data to the servlet engine (both server and client use 
DataInputStream's and DataOutputStreams to read/write data). The server 
then decodes the data, relays the message to clients if necessary, passes 
new messages to clients if the received message demands it and returns a 
response to the client that sent the message. This response also contains 
only raw data, which is usually (but not always) no more than an 
acknowledgement. Clients get their messages by polling the game server 2 
times/second (they do this by sending a special message to the game server 
servlet, which in turn writes back all of the clients' messages as a 
response to the 'request' containing the message). The clients need to 
poll because we can only use the request-response paradigm, since the 
server should be accessible from behind a firewall. The server expects 
connected clients to fetch their messages at least once every 2 minut
 es, and checks this by dropping a 'ping' message in all its client 
message queues, and verifying that it gets consumed within 2 minutes.

[OT] Servlet process issue

[Tam, Michael]

Hi all,

Sorry for the [OT].  Since many of you are the experts on servlet
technology, I'd like to ask for suggestions or comments on the servlet
process I am working on.

Process:
1)  I have a form html (A) to upload data files through an UploadServlet (B)
which stores the files in the file system.
2) Then (B) will forward the request to ValidationServlet (C) which reads
the files for validation and generates log file.
3) Then (C) will forward the request to LoadServlet (D) which use the log
file to load the clean data to DB.

My question:

What will happen when the process reach 3) and assume it has finished half
of the data loading and the client stop/close the browser?

My understanding is the process will terminate at that point.  This implies
I have to somehow monitor the request so when this condition happens, I have
to reverse the process.  If so, what's the best way to do this?

Or better, what is the best way to spawn another process to perform the
validation and loading after the files being uploaded to avoid the client
interferes the process accidentally?


Any input would be appreciated.  Thank you.

Michael

Re: mod_jk installation

[Albert Lunde]

I am trying to configure mod_jk 1.3 to work between Apache 1.3.27 with
mod_ssl and Tomcat 4.1.18 on Linux Version 7.1.
After installing Apache 1.3.27 and Tomcat 4.1.18 when I update
httpsd.conf with following two lines "LoadModule jk_module
/libexec/mod_jk.so" "AddModule mod_jk.c"
And then when I restart Apache 1.3.27 I get the following error:
=
Cannot load /usr/local/apache_1.3.27/libexec/mod_jk.so into
server: /usr/local/apache_1.3.27/libexec/mod_jk.so: undefined symbol:
ap_ctx_get
./httpsdctl start: httpsd could not be started.
===
I had a similar error that I fixed by changing the order modules were
loaded/added in httpd.conf: it was mod_jk using a routine from an
non-core Apache module. But I just tried searching the Tomcat/Apache
1.3.27/mod_jk sources for the string "ap_ctx_get" and I couldn't find
it, so I can't confirm that is the explanation here. The "ap_" makes
me think it's an Apache routine. Could you be using mod_jk
built for the other Apache version (2.x)?
(I'm also still unable to get Apache 1.3.27+mod_jk+CoyoteConnector
all working together, but I'm stuck an a different error.)

Re: Connection drops with tomcat-based game server (very short version)

[Wouter Bijlsma]

There's nothing in the logfiles (we are only using catalina.out) that would suggest 
that Tomcat even knows about a connection problem. The server just goes on as if 
nothing happened, but the messages it sends to the 'dead client' are never delivered. 
This might indeed be a load/config issue, although some users experienced the problem 
even when only 3 users were logged in. The confusing part is that we just cannot 
reproduce the bug on a fast network (not even with 15 users logged in), while neither 
the client nor the server use time-sensitive code for sending or receiving messages.

We are using tomcat 4.0.6 on a Debian/testing linux machine, kernel version 2.4.20

That's one way.  It pretty much comes down to how you want to handle 
Contexts.  If you want a particular Context to be available for a 
particular domain/host and that domain/host only, you would use a separate 
Host container.

Re: tomcat responds with localhost, but refuses the connection w/mach inename

[John Turner]

Did you configure a virtual host for machinename in server.xml, or just 
leave it with localhost?  Tomcat is literal, there is no catch-all like 
there is with Apache.  That is, unless you have a Host container for your 
hostname or an Alias directive for an already existing virtual host, Tomcat 
will not answer the request.

Form based authentication and sessions

[Carl Maib]

hello all,
i am having trouble getting form based authentication working the way i would like. as 
suggested by several threads in this group, i am trying to override the authenticate 
of the FormAuthenticator so that i can set session data appropriately.

the problem i am having is that i am unable to get this to build and link as described 
in the examples. a quick summary of what i am trying to do can be found at 
http://tomcat.mslinn.com/tomcat/realms.html (see bottom of the page for tomcat 4.x).

i believe my problem is that i am not quite sure how to best link into use tomcat's 
native classes. i am not even sure if this is allowed, given the tomcat4 docs indicate 
catalina.jar classes are invisible to web apps, as mentioned below. 

Catalina - This class loader is initialized to include all classes and resources 
required to implement Tomcat 4 itself. These classes and resources are TOTALLY 
invisible to web applications. All unpacked classes and resources in 
$CATALINA_HOME/server/classes, as well as classes and resources in JAR files under 
$CATALINA_HOME/server/lib, are made visible through this class loader. 

so, if they are invisible to webapps, are you not suppose to use them? if allowed, how 
can you get to them?

can someone point me in the right direction, as far as how best to get rid of compile 
time errors (e.g. unknown symbol HttpRequest) and runtime errors which include class 
loader exceptions for FormAuthenticator (tomcat class).

any help would be greatly appreciated!

thanks...

jspC

[Matthew Oatham]

Hi,

I am trying to run the jspc command and am experiencing some problems!

I get errors about classes not being found, is there any way to reference
classes from the CLASSPATH in the jspc task or do I have to put all the
class files needed by the web app in the WEB-INF/classes / WEB-INF/lib
directories?

Thanks.

Matt

Re: Connection drops with tomcat-based game server (very short version)

[Jake Robb]

This is an interesting proposition!  I read both of your posts.

Personally, if I were you, I would create a custom server.  David Flanagan's
Generic Multithreaded Server (as given in O'Reilly's Java Examples in a
Nutshell) would be a good starting point (if you're using it commercially,
there's a $50 license fee).

http://www.davidflanagan.com/javaexamples2/

I've never had Tomcat exhibit the request-killing behavior you describe.  I
have also never used a GenericServlet, so that could possibly be the cause.

Re: no Tomcat process & error stopping service (Red Hat 8.0)

[John Turner]

OK, so I'm guessing Red Hat Linux, and you used the RPMs.

You should be getting a default page at http://server:8080, though I do not 
know what the RPMs do...they may disable the root context.  Try 
http://server:8080/examples/ or http://server:8080/examples

Regarding your process problems, you typically won't see it because "ps" 
has column clipping.  To really see what is going on, try something like:

ps -ef --cols=200 |grep java

In any case, if you are getting an error message on port 8080, Tomcat is 
running.

Re: Connection drops with tomcat-based game server (very shortversion)

[Ben Ricker]

Sounds like a load issue coupled with a config issue. How about some
logs entries? DO you see anything in the logs you setup? Catalina.out?
Context log?

Also, some idea what OS and version would also be helpful. It is nearly
impossible to tell (at least for me).

RE: Connection drops with tomcat-based game server (very short version)

[Filip Hanik]

ok, if you are using the HTTP protocol, you must know that the server has no 
responsibility in keeping the connection alive.

Tomcat (Coyote) keeps the connection alive if the Keep-Alive is set, but you can't 
send raw data up and down the HTTP connection and expect it to work. The data has to 
be contained within an appropriate HTTP request.

But no, I've never seen tomcat not respond to a request, at least it will send down an 
error code to the client at worst.

Apache1.3.27 + Tomcat 4.1+FreeBSD4.7

[Marcia de Oliveira Cardoso]

Hello,

I never configured this before. 
I've installed Tomcat4.1 (by ports) standalone and it seems to work fine. I enter 
http://localhost:8180 and it says "welcome".
But I need my to have something like that: http://localhost/~user (any user )
So, I read that I'll need mod_jk. So I installed (Freebsd ports) it. (and 
jakarta-tomcat3.3).
I added the module to Apache.

And now...??
I need a complete HOW_TO.

Thanks
Marcia

No idea here.  Have you used netstat to make sure something else isn't
already listening on that port?

Do ps -ef | grep java and see if you have any java processes running.  If you
are getting the Tomcat error 500 below, it should be there.

I think the root context is disabled by default in server.xml.  Open it up and
uncomment the context entry for root, and for /examples if you want.  Look for 
the comments that say "Tomcat Root Context" and "Tomcat Examples Context" (at least
mine does - tomcat 4.1.18.

Connection drops with tomcat-based game server (very long version)

[Wouter Bijlsma]

Hi,

I'm currently co-developing a game (draughts, see www.damserver.nl) server that 
utilises Tomcat for message passing and relaying, which is in a testing phase right 
now. During development of the server (on a fast network) we encountered no big 
problems with Tomcat, but since testing has intensified somewhat (especially by 
testers on slow modem connections) it sometimes seems like Tomcat drops connections to 
clients randomly every now and then.

In short, the server works a bit like a chat server, with the exception that not only 
chat messages are relayed by it, but also moves, connection state information, user 
actions etc. The server keeps no internal state about board setups etc. (this is all 
handled by the clients), but only which users are logged in, where these users are at 
any moment (portal, room, table screen), and what games are being played by which 
users. Clients communicate with the servlet engine through only 1 servlet (this is 
because the servlet specs advise against sharing state information between servlets), 
which acts like a 'proxy' between the network and the server logic. We don't use the 
HTTP protocol (ie: we dont use HttpServlet but GenericServlet), but we do use the HTTP 
port. 

Messages are encoded and sent (by 'requesting' the game server servlet) as raw data to 
the servlet engine (both server and client use DataInputStream's and DataOutputStreams 
to read/write data). The server then decodes the data, relays the message to clients 
if necessary, passes new messages to clients if the received message demands it and 
returns a response to the client that sent the message. This response also contains 
only raw data, which is usually (but not always) no more than an acknowledgement. 
Clients get their messages by polling the game server 2 times/second (they do this by 
sending a special message to the game server servlet, which in turn writes back all of 
the clients' messages as a response to the 'request' containing the message). The 
clients need to poll because we can only use the request-response paradigm, since the 
server should be accessible from behind a firewall. The server expects connected 
clients to fetch their messages at least once every 2 minut
 es, and checks this by dropping a 'ping' message in all its client message queues, 
and verifying that it gets consumed within 2 minutes.

The problems we encounter seem to surface only when a client connects using a 'slow' 
connection, especially with modem connections but maybe also with cable connections 
(which have little upstream bandwith). The symptoms are that after some time playing a 
game a client does not receive messages anymore. The game server keeps working fine, 
and the client also goes on happily. It just does not receive any more messages, 
although the server definitely sends them. Ofcourse this probably looks like bug in 
our code, but we do not think this is the case, since we cannot reproduce the bug on a 
fast network. It seems as if the Tomcat server sometimes randomly kills a request 
(especially under heavy load) without sending a response. The client thread that polls 
the server still expects this response but it does not get it, so it blocks, and no 
new requests for messages are made. After some time the game server detects that the 
client did not consume its messages, and logs out the user.
  As a side note I would like to mention the fact that we had to increase the maximum 
number of simultaneous threads per servlet to get acceptable performance if more than 
8 people were logged in at the same time,

Now for the question this post is all about: is it possible that tomcat sometimes 
randomly kills a request, does not process a request or queues a request indefinitely, 
thereby blocking all further communication with a client? Is this possible because the 
server communicates with the clients using only raw data and 
InputStreams/OutputStreams? And: is it a good idea to develop a game server like the 
one described here using Tomcat, considering the fact that tomcats main purpose is to 
act as web application server using a strict request-response paradigm. Our project 
development team suspects that tomcat was never meant for this type of applications 
(that produce very small, but very frequent requests, and are really 
connection-sensitive), and that it is not safe to assume that every request made by a 
client always yields a proper response. 

Don't get me wrong: I do *not* think there's something wrong with tomcat! As a matter 
of fact I have really good experiences with it using it for web applications!!

Re: What to set docBase attribute to in an individual Context.xml fil e

[Jacob Kjome]

Note that "context.xml" is only applicable when you are using the "deploy" 
task for the manager app (and note that this can only be invoked via the 
Ant catalina manager tasks because browsers don't support HTTP PUT).  If 
you are putting a context configuration file in the webapps directory for 
deploying a .war file or a directory relative to (or inside) the webapps 
directory, then name the file anything you want.  I would recommend, 
however, that you name the file the same as you named the .war file or 
directory you are deploying.  This makes it easier to know, at a glance, 
which context configuration file is for which app.

Actually, as part of the deploy process, Tomcat looks for the 
META-INF/context.xml file inside your .war file and extracts that to a file 
named the same as the .war file, less the .war extension.

So, if you have...

myapp.war

Then META-INF/context.xml gets extracted (in the same directory where the 
.war file exists) to...

myapp.xml

Hope that clears things up.

I've done that before now, when I've needed to add contexts without
editing server.xml - BUT those files have gone into the webapps directory
(where a warfile would normally go) - see manager.xml which I think is in
webapps/ by default. This context.xml method sounds like a safer
solution though...

RE: no Tomcat process & error stopping service (Red Hat 8.0)

[Lisa Foister]

I am logged in as root, with no other web server running, so I don't know 
why I'm having trouble with port 80, unless somewhere the tomcat process is 
configured to run as the tomcat4 user.  However, I changed my server.xml to 
use port 8080, and at least I'm not getting errors on stopping although I'm 
still not seeing it on the process list when it's running -- or maybe I'm 
just not looking for the right thing?  When I http to port 8080 on that 
machine, I now get a Tomcat-style error message (which at least indicates 
to me that it's probably running, if possibly configured incorrectly), 
"HTTP Status 500 - No Context configured to process this request". 
 Shouldn't I be getting some sort of default home page?

Thanks!

Re: Whee!! It's good to be back!

[Jeff Tulley]

How are you packaging it?  Are you putting it in a certain context, or
what?
How are you trying to view it?  Through Port 8080, or through a web
server?
It seems that your web.xml is consistent within itself.  Where are you
putting the compiled .class file in your web app's directory structure?

It's very good indeed to be back in your "midst" again, and believe me,
I will try hard to "mind my manners" and try to use this list for the
most knowledgeable insight that I can posssibly get about how to execute
certain jsp's/servlets with the Tomcat web container!!

Case in point: I am having problems with trying to see this
"TodayServlet.java" servlet of mine. It just flat doesn't show up in my
browser when I try to look at it, sad to say. It is just the most simple
and basic servlet, so it shouldn't be too much of a "big deal" to
correct whatever problem it has, so I could then see it. I naturally
have attached it to my posting, and again, it's good to be back "in your
good graces" again. 

p.s.: excuse my absolute ignorance about how servlet creation is done
successfully, but I was wondering if I possibly need a HTML file to go
along with this servlet as a helper file.

I'm running in standalone mode and I'm receiving the same error, so, I don't
think the problem is with regard to what version of Apache you're running or
mod_jk.

Re: no Tomcat process & error stopping service (Red Hat 8.0)

[Ramsay Domloge]

if you do "netstat -l" you should see that there is already an app using 
port 80. Either that or you are trying to run Tomcat not as root which 
will be denied since ports 0 - 1024 are restricted to root only.

Re: no Tomcat process & error stopping service (Red Hat 8.0)

[Tim Funk]

It looks like something is already listening on port 80.

netstat -a will show if anything is listening on port 80.

You also need to be root to bind to port 80. It looks like you already 
are but make sure your scripts are not switching user. If you are just 
running startup.sh --> then you should be ok and something else is 
already listening to port 80.

Re: no Tomcat process & error stopping service (Red Hat 8.0)

[John Turner]

Tomcat is trying to bind to port 80 but doesn't have the permission to do 
so.  Are you running these scripts as root?

Check /path/to/tomcat/conf/server.xml and make sure that CoyoteConnector is 
listening on port 8080 (the default) instead of 80.  You can always change 
it later, and there are no permission restrictions on port 8080.

I think I may be having the same problem as well. I'm running Tomcat in
standalone mode and I have it configured only for HTTPS. The error message
that I'm receiving is.

INFO: All threads are busy, waiting. Please increase maxThreads or check the
servlet status75 75

This is the second time I've seen this. I don't think I've seen the problem
before upgrading to 4.1.18.

RE: no Tomcat process & error stopping service (Red Hat 8.0)

[Davis, Jeremy]

Do you have a webserver already up and listening on port 80?  I don't know
for sure, but that would be my first guess, if that helps.

hmm... ok, here's what's in the log (this should be exactly one start and 
stop -- the first 2 or 3 entries are from the start, the rest from the 
stop).  I don't seem to be getting any errors at all on startup.  No clue 
what "Error initializing endpoint" means, but it seems to be my first

Re: no Tomcat process & error stopping service (Red Hat 8.0)

[John Turner]

Tomcat is definitely not starting.  Check the catalina.out file for an 
explanation, and you can also try to start it manually with 
"/path/to/tomcat/bin/catalina.sh start" which should put any startup 
problems right to the screen.

What os and file are you using?

If it is a tar.gz (.tgz) file - you need to your GNU tar since tar from 
proprietary unixes may not work right (solaris/hpux). PKunzip also 
doesn't like tgz files either.

Re: Corrupted file

[Tim Funk]

What os and file are you using?

If it is a tar.gz (.tgz) file - you need to your GNU tar since tar from 
proprietary unixes may not work right (solaris/hpux). PKunzip also 
doesn't like tgz files either.

Make sure you have as many tomcat workers(maxProcessors) as apache workers.

- the logs show nothing strange; I've set up with request dumping now
- I'm playing with the params for the tomcat.exe in the registry (-Xrs, JVM 
dll, garbage collection options)
- traffic is really low but that doesn't seem to make a difference.

This afternoon it seems to be behaving itself... but it can take upto a day

How much $$ to get Tomcat/J2SE installed?

[Chris Hale]

All,

Looking for some quick help here.   Need to get this installed on my RH7.3
system with Apache and mod_ssl.  My developer is doing some stuff with .jsp
files and needs this support on the server.

Anyone willing to do this for some quick cash?  I tried to get it installed
and got stumped pretty fast.

Send me your credentials and a fixed price for doing this.  The server is a
hosted virtual private server.

I've done that before now, when I've needed to add contexts without
editing server.xml - BUT those files have gone into the webapps directory
(where a warfile would normally go) - see manager.xml which I think is in
webapps/ by default. This context.xml method sounds like a safer
solution though...

Hi Jake,

Thanks for getting back so quick. So the context file in META-INF should be

That is maybe where I have been going wrong, I read some previous posts on

I'll try what you say.

Re: What to set docBase attribute to in an individual Context.xml fil e

[Jacob Kjome]

First, the name of the context configuration file put into META-INF should 
be, very specifically, "context.xml".  The docBase needs to be name of your 
.war file.  So, if you your .war file is "MyWarFile.war", then it should be 
docBase="MyWarFile.war".

1.4.1_02 is the latest.
I have had this problem with 4.0.6 running standalone with 1.3.x Upgrading 
to 1.4.1_01 helped.

I have a NT4 box with 4.0.6 standalone on 1.4.1_02 with coyote connector

Re: Deploy with Ant tasks

[Jacob Kjome]

The behavior of install and deploy are very different.  "install" runs your 
app from wherever you point the docBase to.  deploy using HTTP PUT to 
upload the war file to the manager app work directory (as you've 
found).  Also, deploy is permanent (at least until undeploy) as it causes a 
physical modifcation of server.xml which "install" does not.

Now, as far as reading config files, you must be counting on File IO to 
read the files.  This is not portable.  You should be doing no file IO 
except to, possibly, directories specified via server configuration of the 
tempdir that the servlet spec defines.  To read properties files, use the 
following...

InputStream is = 
getServletContext().getResourceAsStream("/WEB-INF/my.properties");

The feed the inputstream into a Properties object.

This will work whether you are deploying from a .war file or from a 
directory.  This is the correct way to do things.  If you don't want to do 
this, then don't expect the deploy task to work for you.

Hi,

When using the Tomcat Ant tasks to deploy (install or deploy) a war, where
should the war and extracted archive end up?
Is it supposed to deploy to the work subdirectory or webapps?

The problem I am having is that I get a nearly successful deploy with either
install or deploy - the war ends up in the manager subdir (as expected) and
the jars from the war are extracted to an appropriate work subdir (as
expected), but the properties files in the war (in WEB-INF) are not
extracted to the WEB-INF dir of the appropriate work subdir - which is an
unexpected error.  So when the app starts, errors occur from lack of reading
the needed property files.
Also, no files are placed in the webapps dir structure as when placing a war
in the webapps dir, but I interpret this as expected behavior from the
docs.(?)
I am wondering if I am missing a configuration item or similar, but cannot
determine what.
I have spent many days trying different things and searching the web and
archives with no info.  Is there something in the docs I have missed?
Appreciate any pointers or answers.  TIA.

MemoryRoles Roles and Users

[Francois Paris]

Hi,

I am trying to list the current user roles, but I don't know very well how I can do it.

I am using Tomcat/4.1.18.

I have found in the servlet api doc and Catalina api doc, two interesting methods : 

API Servlet :  HttpServletRequest.getUserPrincipal()
API Catalina:  GenericPrincipal.getRoles()

Any ideas ?

Thanks in advance.

François.

Here is the error on catalina.out

Mar 20, 2003 9:34:30 PM org.apache.tomcat.util.log.CommonLogHandler log
INFO: All threads are busy, waiting. Please increase maxThreads or check 
the servlet status75 75

maxThreads is set to 75 but we haven't more from 2-3 concurrent users so I 
think this is not th problem.

We tried to run again the old server, but now we have a very strange 
error, we can execute servlets but not jsp pages. Here is the error 
received by the browser:

Apache Tomcat/4.0.1 - HTTP Status 503 - Servlet jsp is currently unavailable

this happens too to the examples directory, I think it's not caused by the 
application...

I'm going crazy, somebody could help?

Thanks in advance

Tomcat MBeanServer and Registry

[dubstar 27]

Hi,

I'm trying to get retrieve my JMX registry and MBeanServer in a Java 
servlet:

registry = (Registry) getServletContext().getAttribute 
("org.apache.catalina.Registry");

mBServer = 
(MBeanServer)getServletContext().getAttribute("org.apache.catalina.MBeanServer");

However, I get null for both registry and mBServer.

Is this how it's supose to be done? Are there steps before this that I 
should do in order for my code to work properly?

Regards,
Nicolas

[JK2] JK2 Properties for Coyote Connector

[Jerry Jalenak]

Hi,

I'm trying to get the Coyote Connector working with Apache 2.x and Tomcat
3.3.1.  I've been through the Coyote 1.0rc2 doc and have updated all of the
.jar files in Tomcat.  What I'm missing is the JK2.properties file.  Does
anyone have an example of what this file should look like?  

TIA!

Re: JNDI problems

[Andoni]

Could it be because of the conflict between the declaration of the resource
as being "shareable" in the server.xml file and being Container in the
web.xml?

I am very new to this stuff.

JNDI problems

[TimothyReaves]

 Hello all.  I have been using Tomcat 4.x, and it's worked very well.
I had a data source defined in struts, and that worked very well.  Then I
had a need to access a database from a non-JSP class, so I figured I'd use
JNDI.  Oddly enough I got this to work the first time.  Then I went to
tweak it, and now it does not work at all.

 Here is my server.xml settings:

 
 
  
   driverClassName
   org.postgresql.Driver
  
  
   factory

org.apache.commons.dbcp.BasicDataSourceFactory
  
  
   maxActive
   100
  
  
   maxIdle
   2
  
  
   maxWait
   5000
  
  
   password
   
  
  
   url
   jdbc:postgresql:performance
  
  
   username
   perfserver
  
  
   validationQuery
   
  
 



Here is my web.xml entry:


 DB Connection
 jdbc/PerformanceDatabase
 javax.sql.DataSource
 Container



Here is my code to get a connection:
private static Connection getConnection(){
 Connection connection = null;
 try {
  Context ctx = new InitialContext();
  if (ctx == null )
   throw new Exception("Boom - No Context");
  System.out.println(" getting data source");

  Context environmentContext = (Context)ctx.lookup
("java:comp/env");
  DataSource ds = (DataSource)environmentContext.lookup
("jdbc/PerformanceDatabase");

  System.out.println(" got datasource");

  if (ds != null) {
   System.out.println(ds);
   connection = ds.getConnection();
  }
 System.out.println(" got connection");
 } catch (Exception e) {
  e.printStackTrace();
 }
 return connection;
}


 The sys.out 'got datasource' prints, but it never gets to 'got
connection', and no exceptions are thrown.  It just hangs.  There is no CPU
useage, so this leads me to think that there is some blocking going on.
Perhaps the getConnection just isn't able to do something, I just don't
know what.

 Any ideas?  Thanks!

What to set docBase attribute to in an individual Context.xml file

[Collins, Jim]

Hi,

I am deploying my application using manager/deploy. In the META-INF
directory I have myapp.xml file. If I am deploying the app using manager
does anyone know what I should set the docBase attribute to? I am also
having problems reading an Environment property from the context file. 

Here is my context file:



  


In my code I try to do this:

_ic = new InitialContext();
log.debug("Test look up = " +
(String)_ic.lookup("java:comp/env/Test"));

But I get an error saying  "Name Test is not bound in this Context"

If however I have this entry in the web.xml file it works:



Test

Test
This is a test
java.lang.String


If anyone could shed any light on this it would be appreciated.

Thanks

Jim.

Re: Setting up permissions for jsp directory

[Tim Funk]

The easiest way is to place your jsps inside of your WEB-INF directory.

Otherwise - if you are using apache in front of tomcat there are 
directives which can do that.

Otherwise - You can create a security constraint which nobody has access 
to. (Configured in web.xml)

Lb_factor didn't work as expected

After several

For example if we
stress with 100 users, 80 are routed to the first tomcat server declared in workers.properties
and 20 are routed to the second.

RE: Setting up permissions for jsp directory

[Manav Gupta]

In essence, your jsp is 'separated' from your controller servlet. 

1. You can either plug-in the validation mechanism on top of each jsp page
such that each jsp page talks to the servlet before processing (but i
presume you wouldn't want this).
2. You can use JDBC Authentication Realm. Check
http://tomcat.mslinn.com/tomcat/realms.html and
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/realm-howto.html#JDBCRealm
for more information.

Ivan,

Thanks for your reply.  When you restart Apache, do the threads just build
up again?

If you can't see any difference between the two configurations, do you think
there may be a difference between the libraries being used?

Servlet, Tomcat 3.3, IIS virtual directory access denied

[Cinzia S]

Hello people,

I've set up Tomcat to run as a service with a domain log on usr/pswd. IIS
works fine redirecting servlet requests to Tomcat via ISAPI redirector. All
on Windows 2000 Server.

The problem:
The java application creates and reads files from a location which
corresponds to an IIS virtual directory and is also a local directory with
respect to the Tomcat and IIS installation. The application is denied access
to this directory when submitting a network path (\\server/drive/directory/)
where to store and read files, but is happy when a local path is given
instead (E:/) Why? The domain user should have complete access to this. Is
it Tomcat, IIS, or java restrictions?

I appreciate any suggestion on this
Thanks
