RE: Problem with logging in Eclipse
Anybody else have this problem??? Thanks Donie -Original Message- From: Donie Kelly [mailto:[EMAIL PROTECTED] Sent: 28 October 2004 11:12 To: Tomcat Users List Subject: RE: Problem with logging in Eclipse Hi guys I have the same problem and it's driving me nuts. I have a run configuration in Eclipse 3.0 for tomcat 4.1.18 and I call bootstrap.jar directly within eclipse to start tomcat. The only jars I put in the run configuration class path are the tomcat ones. This starts tomcat as it would be normally run and tomcat then inits the webapps directory and creates the classpath for each webapp based on the contents of the WEB-INF/lib. I have commons-logging.jar in my WEB-INF/lib as it's required by some code. This has problems finding log4j even though it's there. When I send in a request that uses com.sun.xml.messaging.saaj.soap.dom4j.ElementFactory tomcat throws an exception into Catalina.out log showing the following stack trace below. Now, if I put log4j.jar into the run configuration class path the problem goes away? Why can't tomcat find this jar under Eclipse 3 However, because I have multiple webapps running, the logging for the different webapps is the same as the log4j.jar is now global so the last webapp to init sets the logging scheme and location. Painful.

Tomcat fails - Can't read body, waited #0 Seems size related
I have a servlet that recieves data from a client. All the servlet is doing is reading from the InputStream of the HttpServletResponse (BufferedReader br = new BufferedReader( new InputStreamReader(request.getInputStream()));) and writing the data to a disk file. Periodically Tomcat refuses to read the data and dumps with an IOException (attached below). I've googled for the error message but all I can find is references to CVS versions of the AJP13 code - which puts me out of my depth. I can't find any reference to the error message in the list archives. The "odd" thing is this seems to be related to the size of the data stream. The data is actually an Order Confirmation and when the order contains five lines at 7745 bytes everything works OK. When the order contains 6 lines (or more) at 8862 bytes then I get the dump. It's not related to the data content - I've tested this by using known good data. I'm using Tomcat 4.1.7-LE-jdk14 - upgrading is an option, but not one I will be able to undertake lightly.

Active connections in db pool
Is there a way of finding out how many commections which are currently active when using a db connection pool? I got this error message in my logs: "Cannot get a connection, pool exhausted". When I increased the number of mxActive the error message of course disappeared. I tripled the number of connections just to make sure that it will not happen again for some while, but I would like to check the value from time to time so I can increase it yet again if that would be necessary or decrease it if I really needed just oldMax + 10.

RE: OutOfMemoryError: unable to create new native thread
Hi. No problem! :) Reduced Maintenance is definitely one reason. Another reason is that I generally share a connector on the same port/protocol - and place all of these in a The other connectors are all for HTTPS sites - each running on the same port but bound to different Ips. I also have a management tool that abstracts all the conf entries - and doing this in one tomcat instance is easier than with multiple!

Re: Problem Authenticating Users in LDAP
So your user hasn't been authenticated by the JNDIRealm. Is there any
security role specific stuff?? You have to distinguish between
authentication and authorization (roles etc.) Can you trace your ldap
engine??? We are facing problems with german umlauts in passwords
(JDBCRealm). Do you have any chars within user/password which need
special encoding???

prompts me for the username and password. When I type in these

Re: Problem Authenticating Users in LDAP
I guess in the LDAP directory, the password is not stored as a clear
text but in an encrypted manner using SHA (Simple Hashing Algorithm).
Can that be the reason for not authenticating this user? And I don't
have any special characters embedded in my username/ password.
Also, I can trace my LDAP directory, without any problems, though.

Re: Problem Authenticating Users in LDAP
Hi,
took this from the documentation
For each of the standard |Realm| implementations, the user's
password (by default) is stored in clear text. In many environments,
this is undesireable because casual observers of the authentication
data can collect enough information to log on successfully, and
impersonate other users. To avoid this problem, the standard
implementations support the concept of /digesting/ user passwords.
This causes the stored version of the passwords to be encoded (in a
form that is not easily reversible), but that the |Realm|
implementation can still utilize for authentication.
Digested passwords are selected by specifying the |digest| attribute
on your || element. The value for this attribute must be one
of the digest algorithms supported by the
|java.security.MessageDigest| class (SHA, MD2, or MD5). When you
select this option, the contents of the password that is stored in
the |Realm| must be the cleartext version of the password, as
digested by the specified algorithm.
When the |authenticate()| method of the Realm is called, the
(cleartext) password specified by the user is itself digested by the
same algorithm, and the result is compared with the value returned
by the |Realm|. An equal match implies that the cleartext version of
the original password is the same as the one presented by the user,
so that this user should be authorized.
So give it a try and please feedback some information.

Also, I can trace my LDAP directory, without any problems, though.

Hi,
I have a problem trying to authenticate users, whose details are
stored in the LDAP directory through Apache Tomcat. The details of the
software I am using are as follows :
LDAP: OpenLDAP V 2.2.17
Web-Server: Apache-Tomcat V 4.1.30
OS: Suse - Linux
The LDAP directory structure is somewhat like this -
dc=my-domain,dc=com
cn= Manager
cn=person1
cn=person2 and so on
In the server.xml file (under APACHE-TOMCAT-DIR/conf/) I have included
he following piece of code -
ldap://localhost:389";
roleName="cn" roleSearch="(uniqueMember={0})"
userPassword="userPassword"
userPattern="cn={0},cn=Manager,dn=my-domain,dn=com" />
The folder I have to authenticate is "param_test" and this resides
under "APACHE-TOMCAT-DIR/webapps".
The web.xml file under the "param_test" folder contains the following
piece of code -
..
test
/*
cn
BASIC
test
..
I have even copied the jndi.jar, ldap.jar files to
APACHE-TOMCAT-DIR/server/lib directory
When I try to access the link, http://localhost:8089/param_test, it
prompts me for the username and password. When I type in these
parameters as per the entries in the LDAP directory, the pop-up
reappears and this goes on continously. If I cancel this pop-up, HTTP
error 401 is returned. Any guesses where I have gone wrong?
Thanks in advance.

RE: OutOfMemoryError: unable to create new native thread
Hi, >Question: Having multiple tomcat instances on the same server - would this >not increase the memory usage - due to multiple JVMs? If configured correctly, the total should be just about the same. It might be a bit higher or lower depending on the semantics of your webapp (% in old generation vs. % new, from a GC perspective). But it shouldn't be a big change from a total memory consumption standpoint. And on the plus side, you'd let each JVM tune itself optimally for its webapp(s), something that's virtually impossible to do with more than a couple of webapps in one JVM.

Re: problems with LD_LIBRARY_PATH !

How do you start your Tomcat?! Trough a init.d script, or from bash, sh
or another shell? If it is from a shell you have to be sure that your
LD_LIBRARY_PATH is set _before_ you start Tomcat, ie try this:
LD_LIBRARY_PATH="/usr/lib:/usr/local/lib:/usr/local/perl/lib"
/path/to/tomcat/bin/startup.sh
Perhaps this happens because you do not call 'export' when setting an
env variable. You have to otherwise it will only exist in the moment you
press enter...

Hi, Ahh, it's great that you tried this: I was just going to ask if the connector is to blame ;) The range of data sizes you mentioned immediately starts the "buffer size alarm horn" in my head ;) 8192 = 8k is the default buffer size for many connector versions, including probably the one you're using.

Hi,
I have a problem trying to authenticate users, whose details are
stored in the LDAP directory through Apache Tomcat. The details of the
software I am using are as follows :
LDAP: OpenLDAP V 2.2.17
Web-Server: Apache-Tomcat V 4.1.30
OS: Suse - Linux
The LDAP directory structure is somewhat like this -
dc=my-domain,dc=com
cn= Manager
cn=person1
cn=person2 and so on
In the server.xml file (under APACHE-TOMCAT-DIR/conf/) I have included
he following piece of code -
ldap://localhost:389";
roleName="cn" roleSearch="(uniqueMember={0})"
userPassword="userPassword"
userPattern="cn={0},cn=Manager,dn=my-domain,dn=com" />
The folder I have to authenticate is "param_test" and this resides
under "APACHE-TOMCAT-DIR/webapps".
The web.xml file under the "param_test" folder contains the following
piece of code -
..
test
/*
cn
BASIC
test
..
I have even copied the jndi.jar, ldap.jar files to
APACHE-TOMCAT-DIR/server/lib directory
When I try to access the link, http://localhost:8089/param_test, it
prompts me for the username and password. When I type in these
parameters as per the entries in the LDAP directory, the pop-up
reappears and this goes on continously. If I cancel this pop-up, HTTP
error 401 is returned. Any guesses where I have gone wrong?
Thanks in advance.
Regards,
Sandeep

Re: channelUnix.file is missing
Thanks,
I modified my jk2.properties but now in catalina.out I have :

How can I load APR ?

In order to use a UNIX file system socket, you need to build and use
jkJNI.so alongside mod_jk2.so.
jk JNI is Jakarta (mod_jk2) Java Native Interface and is neccessary
for UNIX sockets, since that concept is non existant in JVM. Then you
need to tell Tomcat (actually Coyote JK2 module) where that shlib is,
in order to make it possible to use UNIX socket.
This is from my jk2.config
#
# Environment
#
jkHome=Apache-2.0.50-Jk2-2.0.4
jkUSR=/usr/opt/${jkHome}
jkVAR=/var/opt/${jkHome}
# Set the desired handler list

# APR

# UNIX file socket channel

RE: Active connections in db pool
Hi,
This is simple. Code below is for DBCP, the spirit is the same for
other providers:
// Get initial context, naming context
DataSource ds = (DataSource) ctx.lookup("jdbc/mydb");
BasicDataSource bds = (BasicDataSource) ds;
System.out.println("Active connections = " + bds.getNumActive());

Signals sent by Tomcat to web applications during shutdown.
Hi All, I've been having a good shufty through the Tomcat documentation, but I can't find a reference to what signals Tomcat sends to the web applications to shut them down during the shutdown operation. Does anyone know what signals i would need to trap in my code to allow all of my threads to die when tomcat shuts down?

Internationalization of characters --UTF8 encoding
Hi,
I am using Tomcat4.1, Oracle 8i , and XmlRpc to write an application which
is supposed to take japanese characters an insert them into database. Is
there any setting in Tomcat4 where i should be giving the encoding option.
And aslo i get the request from the client in the form of xml and pass that
request via xmlrpc and insert into oracle database.
The client sends japanese characters in Unicode , our database has caracter
set of US7ASCII.
select * from NLS_DATABASE_PARAMETERS where parameter = 'NLS_CHARACTERSET';
PARAMETER VALUE
-- --
NLS_CHARACTERSET US7ASCII
The data is being inserted as all brackets in database.'{{{'
Is there any conversion i need to do while inserting in the database.
Please suggest if anyone has any opinions.

mod_rewrite mod_proxy issues with apache and tomcat
To anyone who can help,
I currently am looking into alternative to mod_jk2 for apache and
tomcat . Simply because of latency issues. One of the avenues that I am
attempting is using mod_proxy and mod_rewrite. I have followed the
directions from this url
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/balancer-howto.html
the only difference between these directions and my implementation is
that I have this
RewriteEngine On
RewriteCond "%{HTTP_COOKIE}"
"(^|;\s*)JSESSIONID=\w*\.(\w+)($|;)"
RewriteRule "(.*)"
"http://${SERVERS:%2|${SERVERS:ALL}}%{REQUEST_URI}" [P,L]
RewriteRule "^.*;jsessionid=\w*\.(\w+)($|;)"
"http://${SERVERS:$1|${SERVERS:ALL}}%{REQUEST_URI}" [P,L]
RewriteRule "(.*)"
"http://${SERVERS:ALL}%{REQUEST_URI}"; [P,L]
instead of what the apache "how to" implements
RewriteEngine On
RewriteCond "%{HTTP_COOKIE}"
"(^|;\s*)jsessionid=\w*\.(\w+)($|;)"
RewriteRule "(.*)"
"http://${SERVERS:%2}%{REQUEST_URI}"; [P,L]
RewriteRule "^.*;jsessionid=\w*\.(\w+)($|;)"
"http://${SERVERS:$1}%{REQUEST_URI}"; [P,L]
RewriteRule "(.*)"
"http://${SERVERS:ALL}%{REQUEST_URI}"; [P,L]
That was just a little tip that I got from a website.
I can get to the urls just fine. For instance if I go to one off my
apps (notice ssl)
https://sdp-webprod.phila.k12.pa.us/masterlogin/
I get there with no problem . Should I take away the trailing slash
and hit enter I end up with the following in my url string
http://170.235.31.19:8080/masterlogin/
Any suggestions?

You can specify parameters for SQL driver when you define DataSource in Tomcat's server.xml. I think most of Oracle drivers can process UTF-8, without the needs for such parameters, but MySQL 3.xx, for example, needs such parameters... Evgeny Javadesk / AllTelescopes __ Do you Yahoo!? Yahoo!

Tomcat in a High Traffic Environment
Dear List, I am new to the list and have a few questions about Tomcat 5.0. We are attempting to use tomcat in a High Traffic, many simultaneous Internet user environment. I have about 8000 simultaneous users, and plan on using 14 web servers. These servers connect via CORBA to a group of backend servers. The 14 web severs are load balanced with a hardware load balancer. How does Tomcat deal with connections? When a request from a user arrives, is it assigned a thread? and is this thread ONLY used for this connection, (including obtaining information from the backend) until the request is finished? How are keep-alives dealt with? When a user requests a keep-alive, is a thread held permanently for this user, until the connection is dropped? If this is the case, how is this ment to scale? A connection pool of 750 threads seems unusable... How can 1 thread per connection scale? or have I misunderstood how tomcat uses its connection pool? And should all of these threads ever have something to do at the same time, the box would just fall over with a load of 750 Would it not make more sense to use a smaller connection pool, and set up queues? Would it not then be better when the request has been processed, to put this into a second queue for requests which then go to the backend, etc, etc? So many threads can't help performance. Wouldn't the kernel be busy the whole time with context switching? and no user would ever get any data back Thanks in advance for any comments, Andrew - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The perl script is well called but

Re: Tomcat in a High Traffic Environment
if you're using hardware load balancer like cisco localdirector, I would setup the load balancer to direct the traffic based on sessionid. this way, you don't need to use keep alive. when you say 8K simultaneous users, what does that translate to in terms of concurrent requests per second? An easy way to figure that out is to use a Http analysis tool like webtrends, or HttpAnalyze to generate statistics. I would look at the peak and average concurent requests. once you know that, it will be easier to determine if 14 servers are sufficient. peter On Fri, 29 Oct 2004 16:53:26 +0200, Andrew Miehs <[EMAIL PROTECTED]> wrote: > Dear List, > > I am new to the list and have a few questions about Tomcat 5.0. > > We are attempting to use tomcat in a High Traffic, many simultaneous > Internet user environment. > > I have about 8000 simultaneous users, and plan on using 14 web servers. > These servers connect via CORBA to a group of backend servers.

Re: Tomcat in a High Traffic Environment
Hi Peter, The load balancer is an F5 and we are doing can do the balancing based on JSESSIONID. At the moment we are doing persistence based on our own cookie (Long story). How did you disable keep-alives? maxKeepAliveRequests="1" ? Doesn't it make more sense to use keep-alives? And what does tomcat really do with these keep-alive connections? Does it really keep 1 thread open for each keep-alive? this seems VERY unnecessary Regards Andrew On 29.10.2004, at 17:02, Peter Lin wrote: if you're using hardware load balancer like cisco localdirector, I would setup the load balancer to direct the traffic based on sessionid. this way, you don't need to use keep alive. when you say 8K simultaneous users, what does that translate to in terms of concurrent requests per second?

Donie, I just noticed this from your log: - Root Cause - java.lang.NoClassDefFoundError: org/apache/log4j/Layout I'm at work right now so can't check my logs at home but if they also point to Layout as the missing class rather than just Log4j that may tell us a little more about what's causing the problem.

Thanks Donie -Original Message- From: Donie Kelly [mailto:[EMAIL PROTECTED] Sent: 28 October 2004 11:12 To: Tomcat Users List Subject: RE: Problem with logging in Eclipse Hi guys I have the same problem and it's driving me nuts. I have a run configuration in Eclipse 3.0 for tomcat 4.1.18 and I call bootstrap.jar directly within eclipse to start tomcat. The only jars I put in the run configuration class path are the tomcat ones. This starts tomcat as it would be normally run and tomcat then inits the webapps directory and creates the classpath for each webapp based on the contents of the WEB-INF/lib. I have commons-logging.jar in my WEB-INF/lib as it's required by some code. This has problems finding log4j even though it's there. When I send in a request that uses com.sun.xml.messaging.saaj.soap.dom4j.ElementFactory tomcat throws an exception into Catalina.out log showing the following stack trace below. Now, if I put log4j.jar into the run configuration class path the problem goes away? Why can't tomcat find this jar under Eclipse 3 However, because I have multiple webapps running, the logging for the different webapps is the same as the log4j.jar is now global so the last webapp to init sets the logging scheme and location. Painful.

Re: Tomcat in a High Traffic Environment
you don't need to use keepalive. generally, in a load balanced setup, keepalive is disabled because the load balancer is already making sure the user goes to the same webserver for the life time of the session. keepalive is usually set in the HTTP header by the client, so I don't think you need to do anything to tomcat's config. someone correct me if I'm wrong. remy can provide a better description of what happens in the case a browser wants to use keep alive. peter On Fri, 29 Oct 2004 17:20:18 +0200, Andrew Miehs <[EMAIL PROTECTED]> wrote: > Hi Peter, > > The load balancer is an F5 and we are doing can do the balancing based > on JSESSIONID.

Basically use the same interface as Runtime#addShutdownHook but implement it to be triggered on actions local to your app. This also helps keep the tomcat specific code and the core business logic code separate.

Yes, but the keepalive is used mainly for making the 'state' out of 'stateless' protocol, and it's main advantage is that you don't need to acquire a new connection all the time. Take a look at RFC2068. Even apache keeps the thread open on keepalive connections (Of course you have a KeepAliveTimeout). Without keepalive your cluster will perhaps work better in the lab, but it will fail in the real-user scenario.

Re: Tomcat in a High Traffic Environment
Hi Yoav, I have not read the Servlet Spec, so please pardon my ignorance. (Definitely do not mean to offend). What I still haven't had clearly answered is: User A sends request (with keepalive) to tomcat. Tomcat assigns request to thread (T1). Tomcat sends result back. Is thread T1 now kept reserved for user A until he/ or tomcat closes the keep-alive connection? If this is the case, and I now have 1000 users, each with 2 connections per user (ie: 2000 connections) do I need 2000 threads? What if the requests each only take a very short amount of time? The server is capable of answering a lot more requests than those from the 1000 users, but due to the number of connections and threads, I am limited to the 1000 users per machine... Or am I just missing something here... I can understand the issue with the one thread one request in the Spec - am just wondering if there isn't a better way, as I can not see how this can possible scale in a high traffic environment - or maybe I just don't understand... :-( Thanks Andrew On 29.10.2004, at 17:28, Shapira, Yoav wrote: Hi, these keep-alive connections?

Re: Tomcat in a High Traffic Environment
The loadbalancer forwards the packet to tomcat, and as such, tomcat sees the keep-alive request. If tomcat has keep-alive enabled, it will set up keep alive on its end.

These servers connect via CORBA to a group of backend servers. The 14 web severs are load balanced with a hardware load balancer. How does Tomcat deal with connections? When a request from a user arrives, is it assigned a thread? and is this thread ONLY used for this connection, (including obtaining information from the backend) until the request is finished? How are keep-alives dealt with? When a user requests a keep-alive, is a thread held permanently for this user, until the connection is dropped? If this is the case, how is this ment to scale? A connection pool of 750 threads seems unusable... How can 1 thread per connection scale? or have I misunderstood how tomcat uses its connection pool? And should all of these threads ever have something to do at the same time, the box would just fall over with a load of 750 Would it not make more sense to use a smaller connection pool, and set up queues? Would it not then be better when the request has been processed, to put this into a second queue for requests which then go to the backend, etc, etc? So many threads can't help performance. Wouldn't the kernel be busy the whole time with context switching? and no user would ever get any data back Thanks in advance for any comments, Andrew - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

(Definitely do not mean to offend). What I still haven't had clearly answered is: User A sends request (with keepalive) to tomcat. Tomcat assigns request to thread (T1). Tomcat sends result back. Is thread T1 now kept reserved for user A until he/ or tomcat closes the keep-alive connection? If this is the case, and I now have 1000 users, each with 2 connections per user (ie: 2000 connections) do I need 2000 threads? What if the requests each only take a very short amount of time? The server is capable of answering a lot more requests than those from the 1000 users, but due to the number of connections and threads, I am limited to the 1000 users per machine... Or am I just missing something here... I can understand the issue with the one thread one request in the Spec - am just wondering if there isn't a better way, as I can not see how this can possible scale in a high traffic environment - or maybe I just don't understand... :-( Thanks Andrew On 29.10.2004, at 17:28, Shapira, Yoav wrote: > > Hi, > >> these keep-alive connections?

Re: Tomcat in a High Traffic Environment
mladen makes a good point. the sites I've worked on, we left the keepalive up to the browser and didn't explicitly disable keepalive. the sites I've worked on we simply used hardware load balancer to make sure the session goes to the right server. that is usually enough from my experience. my bias perspective is, unless the users are sending requests very rapidly, I don't see much benefit to using keepalive. If the interval between requests is rather long, like minutes, I doubt keepalive would provide any measurable benefit.

Correct. The keepalive is usually used for loading a single page with extra content on it, so that browser doesn't need to connect for every single icon on the web page. Of course it's also a backdor for DOS attacks, so it's up to the admin to decide the proper policy.

Hi Peter, I am not using keep-alives to keep session persistence, but was rather hoping for better client performance.

No. If the number of used threads get higher, timeout will be reduced, and if it gets even higher, keepalive will not be used until the number of connections get lower. > Or am I just missing something here... > > I can understand the issue with the one thread one request in the Spec > - am just wondering if there isn't a better way, as I can not see how > this can possible scale in a high traffic environment - > or maybe I just don't understand... :-( If you have that much connections, I think a number of them will be active doing stuff anyway, so the scalability problems will not be on the number of threads. And then you'll have to experiment a little in test environments to see if disabling keepalive (yes, it's maxKeepAliveRequests="1") would be beneficial or not to the stuff you're running. Keepalive does improve performance significantly because it reduces the work of the TCP stack. BTW, Tomcat performs very well without keepalive, as there's no particular HTTP keepalive optimizations (besides benefitting from lower overhead at the TCP level). -- x Rémy Maucherat Developer & Consultant JBoss Group (Europe) SàRL x - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Log4j question
Hi,
Use PropertyConfigurator#configure(URL), where the URL comes from the
Class#getResource or ServletContext#getResource call. You don't need to
get the input stream and read it yourself.
I don't recommend configureAndWatch that much, because it spawns a
thread. Instead, use (from the log4j sandbox) or write a simple servlet
to change logging configuration at runtime.
This discussion is already off-topic for this list. If you'd like to
continue it, please do so on the log4j-user list. Thanks,

Re: Tomcat in a High Traffic Environment
if you're looking for better client performance I would explore other areas first. 1. use gzip compression - this can reduce the html to 1/10th the size. your mileage will vary. 2. caching results on the web-tier 3. putting the images on a dedicated image server 4. distributing your servers across multiple ISP. many service providers don't tell you this, but often their pipe is saturated and can't really handle a large number of concurrent requests. if you host your own servers i would recommend getting more than 1 connection and use different providers Most browsers today are Http1.1 compliant, which means they are limited to 2 connections to the same server. Normally the browser will use the same connection to get the html and the other resources like images and javascript. Are you worrying about images? if that is the case, setup a dedicated image server using apache. you'll easily double the performance of your servlet pages, since tomcat won't have to serve up static content. Plus, it's easier to update the images for the entire site. Rather than copy all the files to every single webserver, you just update the image server and it's done. peter On Fri, 29 Oct 2004 18:01:29 +0200, Andrew Miehs <[EMAIL PROTECTED]> wrote: > Hi Peter, > > I am not using keep-alives to keep session persistence, but was rather > hoping for better client performance.

The F5 load balancers (4.5) have a 'cool-feature?!' that 'forwards' the keep-alive connection through to the backend server - With the 4.5 version of the software they are doing packet mangling. This means that even though the cllient only has 2 connections, the load balancer multiplies this connection to EACH of the backend servers with which the client is communicating, ie: static servers get 2 connections per client, statistic servers get 2 connections per client, tomcats get 2 connections per client.. Version 9 of the software has just come out, and it does proxying this should hopefully help solve this problem - I am still in the process of testing the new version.

There has been some attempts to make the web server as state machine, even for apache. One of the commercial one STM's is Zeus. All that looks very good in the lab environment, not so sure how it behaves in the real-life. MT. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Tomcat in a High Traffic Environment
sounds like your goal is to maximize the number of connections to tomcat while reducing the threads. Would that be an accurate assesment? if that is the case, then I would recommend not using servlets at all. about the only way to do that would be to use a server which multiplexes n connections to a set number of threads. similar to SEDA architecture. neither .NET, J2EE or apache provide these kinds of features. I think there is a webserver based on SEDA design from a commercial company, but I don't remember the name and have never used it. out of curiousity, how big are the pages? if the html is less 1% of the entire page (html, images, javascript, etc), and you have the budget, Akamai might be a viable solution to your problem. unless your webpages use lots of frames and layers, I would guess a single request would only require one connection, since you're already using a dedicated image server.

RE: Upload MS DOC or Image file errors.
Of course, 'it seems to me that convert a byte array of the contents of a MS DOC file to a string cause error'. The contents of an MS doc file are not a set of bytes in a single character encoding.

Character encoding within form based autentication
Hi out there,
I'm still facing problems with the character encoding in TV 5.0.28.
I'm not sure if it's wise to open another thread, but my further
investigation have brought me to a new point, so I think it will be ok
and I'll add the a link to this thread in my previous thread...
Debugging TC I traced my problem down to this method:
// Basically return everything after ";charset="
// If no charset specified, use the HTTP default (ASCII) character set.
public static String getCharsetFromContentType(String type) {
if (type == null) {
return null;
}
int semi = type.indexOf(";");
if (semi == -1) {
return null;
}
int charsetLocation = type.indexOf("charset=", semi);
if (charsetLocation == -1) {
return null;
}
String afterCharset = type.substring(charsetLocation + 8);
// The charset value in a Content-Type header is allowed to be
quoted
// and charset values can't contain quotes. Just convert any quote
// chars into spaces and let trim clean things up.
afterCharset = afterCharset.replace('"', ' ');
String encoding = afterCharset.trim();
return encoding;
}
But how to specify this charset within the html code??? When i try
I'll get the a content type of "application/x-www-form-urlencoded"
When I append content-type="plain/text;charset=UTF-8" to form element,
my conten type won't show up.
I tried several settings of |useBodyEncodingForURI and ||URIEncoding but
won't get it running
Help is highly appreciated.
Thanks in advance
Mark

how to deny .jsp execution within an upload directory
Hello, Can somebody please point me to documentaion and examples that describe how to disallow the execution of .jsp or any other scripts/binaries within a single directory of a webapplication? Part of the web app, is being allowed to upload reports which can then be read and downloaded by another. At this time I can upload a .jsp file and it will run in that directory. I have found much stuff on SecurityManager and syntax within the catalina.policy file but nothing yet that really explains to me what I need to do to accomplish what I described above. My attempts so far at proper catalina.policy systax have not worked. This is a pure tomcat environment running Tomcat 4.1.30 at this time. Other comments regarding the proper use of an upload directory and it's security are welcome. Thank you.

Re: how to deny .jsp execution within an upload directory
I do this by not allowing the upload tool to write files with ".jsp" or ".jspx" extensions in the first place. I also disallow ".." in any part of the filename. You could also write a filter that scans any requests going to that directory and checks for those extensions.

Re: how to deny .jsp execution within an upload directory
The easiest way to do this would be to create a filter on that directory. The filter would either deny access - of it would get the default servlet via the ServletContext.getNamedDispatcher() and then perform a forwards(). -Tim Chris Lawder wrote: Hello, Can somebody please point me to documentaion and examples that describe how to disallow the execution of .jsp or any other scripts/binaries within a single directory of a webapplication?

problem with security manager, plesk and mysql (catalina.policy ignored?)
Hi everybody,
I have problems when connecting to mysql. I'm getting the following
exception when trying to connect to a mysql database:
(SQLException): java.sql.SQLException: Unable to connect to any hosts
due to exception: java.security.AccessControlException: access denied
(java.net.SocketPermission localhost resolve)
I have read about similar problems in google and tried to modify the
catalina.policy without success.
I deploy applications via a Plesk web interface which loads my .war
file, sets it in /var/tomcat4/psa-wars/mydomain.com/ creates a symlink
to the war file in /var/tomcat4/psa-webapps/mydomain.com/ and makes the
application available via mydomain.com/myapplication.
It works fine except when an application tries to access a mysql
database. I´m getting the exception above, even though I tried the
following lines in catalina.policy without success (found similar
exeptions to this one in google):
grant codeBase
"file:${catalina.home}/psa-webapps/mydomain.com/myapplication/-" {
permission java.net.SocketPermission "localhost","resolve";
permission java.net.SocketPermission
"localhost:3306","connect,resolve";
};
grant codeBase
"file:${catalina.home}/psa-webapps/mydomain.com/myapplication/WEB-INF/lib/mysql-connector-java-3.0.9-stable-bin.jar"
{
permission java.net.SocketPermission "localhost","resolve";
permission java.net.SocketPermission
"localhost:3306","connect,resolve";
};
I tried both of them one at a time and I restarted tomcat after every
modification made to the catalina.policy
I´m using tomcat 4.1.24 on a redhat linux Enterprise server, with
/mysql-connector-java-3.0.9 and jre 1.4.2.
Tomcat and mysql are in the same server.
The way I´m trying to access the database in a jsp is
conexion =
DriverManager.getConnection("jdbc:mysql://localhost/DATABASE?user=USER&password=PASSWORD");
I've checked that the database exists, I can connect to the database
from a console as user USER with password PASSWORD.
The application works perfectly well in another server (debian woody
with tomcat 4.0) where it was not necessary to modify the security
policy.
I talked to a friend of mine who also knows something about tomcat and
told me that to access a database in the same server where tomcat is, it
should not be necessary to modify the catalina.policy file.
I have some experience with tomcat but i run out of ideas and things to
try. Any help to open my eyes would be appreciated.
Thanks a lot in advance,
Alfonso

setting JPDA with Tomcat Monitor
I am running Windows XP with Tomcat 5.0.28 JDK 1.4.2_03.
I can tomcat using the JVM debug options just fine when I execute
catalina.bat on the command line (call Catalina.bat jpda start). I have set
the following environmental variables:
JPDA_ADDRESS=8000
JPDA_TRANSPORT=dt_socket
However, I can't get tomcat to run with the JVM debug options when using
Tomcat Monitor. As a matter of convenience I prefer Tomcat monitor and
would like to get it running using this tool.
When I add the "jpda" argument in the arguments input box on the Startup tab
("jpda start") - tomcat will not start up. After clicking the start button
the "Apache Service Manager" window opens for a few seconds and then closes.
Tomcat will generate logs for stderr, stdout and Jakarta_service. However,
they are all empty.
I am sure I am making a silly mistake in how I am feeding the Bootstrap
class the args. Any suggestions?
Carlos

Re: how to deny .jsp execution within an upload directory
For robust installations, this problem is a non-issue due to JSP precompilation. Everyone's situation is different, of course, but it is generally much more secure to precompile your JSPs and disable the dynamic compilation of new ones. justin At 03:25 PM 10/29/2004, you wrote: The easiest way to do this would be to create a filter on that directory.

Log4j with Tomcat webapp
Hi, I am trying to use this under Tomcat 5.0.27.

String baseDir = getServletContext().getRealPath( "/" ); String logPath = config.getInitParameter(log4j-log-path); logPath = baseDir + logPath; File logPathDir = new File( logPath ); System.setProperty( "log.home", logPath ); PropertyConfigurator.configureAndWatch( confFile ); ... When I start my tomcat engine, I do not get any exceptions but my log file does not get created? Am I missing something in my log4j.properties file while specifying log4j.appender.A1.file ? or something else? I do not get any exceptions in catalina.out. I am trying to understand if this problem is due to my configuration of Tomcat or the configuration of my logger? Mufaddal Khumri

This is false. Your cluster will not break in a real-user scenario without Keep-Alive turned on. There are many HTTP servers out there which default to Keep-Alive turned off. Keep-Alive is not used for keeping "state" of a stateless protocol. Pure and simple, it is used to improve client-side performance when requesting multiple resources in a short timespan by reducing the number of TCP/IP connection starts and stops. This is mostly noticable if your website design requires the user to download a large number of small resources to view a page. It is very common to turn off Keep-Alive or significantly reduce it's timeout when attempting to scale to a large number of users without keeping a large number of usable connections idle. You can easily double the number of concurrent users handled by a server by turning off Keep-Alive. The only drawback is that if your pages have a large number of resources to retrieve per page and your users have a high-latency connection to the server. -Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

If you are serving resources which utilize a lot of CPU, then yes, it can be beneficial. You can use the OS's connection backlog on a listening TCP/IP socket as your queue. See the acceptCount parameter of the HTTP Connector. The default configuration has this set to 100. So if you only have 10 threads in your pool and all are busy, the OS will queue up to 100 additional connections to wait for a thread to become free. If more than 100 connections are waiting, any further connections will have their connection refused. > Would it not then be better when the request has been processed, to put > this into a second queue for requests which then go to the backend, > etc, etc? So many threads can't help performance. Wouldn't the kernel > be busy the whole time with context switching? and no user would ever > get any data back Regarding kernel-switching, note my earlier comment that you will find that most connections are waiting for TCP/IP data to be either sent or received. In addition, any modern OS on decent hardware will scale to thousands of threads without any issues. -Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
webapp exceptions redirect them to webapps log

Re: Environment entries question
Hello!
Thank you for reply!
How developers pass parameters to their web applications? There are several
ways of doing it. One of them is: put parameters to web.xml as Environment
entry. It is very convinient.
But it appears that I can change this value in admin application. And this
change is not visible in JNDI :-(
I have to restart tomcat to see new parameters ... or change them in admin
and reload contex.
Maybe it is of no importance for others, but I really care :-)
I made some researches and I think, that
org.apache.catalina.core.NamingContextListener class should be corrected:
it was:
public void lifecycleEvent(LifecycleEvent event) {
...
// Binding the naming context to the class loader
if (container instanceof Context) {
// Setting the context in read only mode
ContextAccessController.setReadOnly(getName());
try {
ContextBindings.bindClassLoader
(container, container,
((Container)
container).getLoader().getClassLoader());
} catch (NamingException e) {
log(sm.getString("naming.bindFailed", e));
}
}
...
}
I think, it should be:
public void lifecycleEvent(LifecycleEvent event) {
...
// Binding the naming context to the class loader
if (container instanceof Context) {
namingResources.addPropertyChangeListener(this);
// Setting the context in read only mode
ContextAccessController.setReadOnly(getName());
try {
ContextBindings.bindClassLoader
(container, container,
((Container)
container).getLoader().getClassLoader());
} catch (NamingException e) {
log(sm.getString("naming.bindFailed", e));
}
}
...
}
With this modification changes in Admin application are visible in JNDI.
Could you please tell you opinion - is this modification ok?
Thank you,
Igor
