Re: strange exception - need advise
Hello! If you want to locate line which causes this error, you can insert loggers on your page. This way you could determine, which line is the reason of error, and what should be fixed. The other possible solution is to set response.setBufferSize(... large number ...); for example, response.setBufferSize(10); in the beggining of the page. Then error page will work properly with this modification, so you will be able to see exception in 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

I think there's been an open bugzilla issue for this for months. It's
such a marginal use-case that (as evidenced by the fact no one's done it

Re: Synchronization in cluster
Hello! if you are talking about distributed locking, then the answer is no Thank you for reply ! Our web application uses locking and Singleton pattern. I am making researches - is there a possibility to move to cluster architecture or load balancing. Distributed locking is not possible. Distiributed Singleton (static variables) seems not to be possible too. So web applications, that use locking or Singleton cannot use cluster architecture or load balancing. Maybe there is indirect way of implementing distributed locking or distributed Singleton? For example, code that needs synchronization may be concentrated in main Tomcat, and other Tomcats will call this code via http or SOAP? Is there any way to move web application with locking and Singleton to cluster or load balancing?

Re: Error page problem
Hello! You probably focused on the rest of your application and didn't notice that the exception occurs in the error page itself. Thank you for responses! May I ask you - how did you conclude that expection occurs on error page itself? I think, exception does not occur on error page. I may be wrong, but I think, that the reason is the following: To notify client of web service, that non standard situation occured, we throw SOAPFaultException in web service. Axis library takes care of this exception and client reseives response with 200 code status. But when error page is defined for context, Tomcat tries to send error page to client. Tomcat tries to reset the response, but it is not possible because Axis library tries to send response too. That is why IllegalStateException occurs. Sending error page (that is intended for ordinary servlets or jsp) does not make sense, because clients expect SOAP messages. Is it possible to remove certain servlets from error page mechanism? Error page does not make sense for web services. Thank you, Igor - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

On 07/09/04 17:42, Jason Palmatier wrote: Has the certificate the SSL/TLS connection uses expired? This will cause the TLS connection to fail to come up. Then, if you have a security constraint defined in your web.xml file that requires TLS for your initial pages, the redirect from your normal port to the TLS port will fail (since the TLS port is not active). Thanks for the idea. Unfortunately, the keystore hasn't changed from the time when everything worked. It is a JKS keystore, contains two certificates. The one is the self-signed CA, the other is for the TLS connection, signed by that CA. Both valid until 2013, for another nine years. Tomcat 5.0.18 worked happily with that keystore for several months. Tomcat 5.0.25 also worked with it for several weeks, until I restarted it few days ago. Besides, just the TLS connection not working is not the problem. When a TLS connector is present in conf/server.xml, nothing comes up, not even the normal port. The normal port (80) is open, but no requests are served. The TLS port isn't open at all, according to netstat.

Re: TLS-Enabled Connector Prevents Startup
I have found the solution and will share it here incase someone encounters a similar problem in the future. The solution is: # cd /dev # mv random random-old # ln -s urandom random however bizarre that may sound. It seems that the recent Linux kernel update wasn't up to Tomcat's liking. For whatever the reason, Tomcat's initialising of the TLS connector blocks in a read from /dev/random, always. Ensuring that it reads from /dev/urandom instead makes it happy again. Although I haven't had anything to try with, I assume that every Java program was affected by this, not only Tomcat. I am also aware of the fact that this kind of solution is far from perfect, but it is a way through until I find something else. Thanks to everyone for answers and suggestions.

You may want to check what the kernel's using as a source of randomness.
I forget the details, but IIRC /dev/urandom never blocks, whereas
/dev/random may block under {some condition I can't recall in detail}.
Well, the server in question is a vServer, a virtual server which shares
the physical hardware with other virtual servers. The machine is hosted
on provider's land and I have no physical access to it. All I can do is
a ssh to my vServer instance. So, whatever it uses as a source of
randomness, I have no way of discovering or changing it.
And you are right, /dev/random will block if you try to read more random
bytes than it currently has in the pool, it will wait for more random
data to become available. /dev/urandom won't block if you ask for more
than it has, it will give you what it has and perhaps inform you somehow
that it wasn't as much as you requested.
My linking /dev/random to /dev/urandom may well affect the quality of
the encrypted connection, depends on how the underlying TLS library
handles the random sources. In this case it thinks that it reads from
/dev/random, so I guess that my solution can result in poor encryption
keys. It isn't advisable for high security environments to follow my
solution, but rather to check their random sources, as you suggested. In
my case, I am one man and that server is my private hobby, a bad key
with less random background than it should have is still more than good
enough.

TLS-Enabled Connector Prevents Startup
Hi there. On one day, an otherwise perfectly functioning Tomcat stops responding to requests. The log file says that one of the threads received an OutOfMemory exception, so I restart the server. Not a big deal, it has happened before. But this time the server never comes up, it hangs somewhere. Some experimentation has shown that it works again if I remove the TLS-enabled connector from the conf/server.xml file. I have two connectors there, one for HTTP, the other for HTTPS. Both worked good until this last crash. Now, for some mysterious reason, if the HTTPS connector is present, the startup of Tomcat shows the following messages: Sep 4, 2004 5:21:12 PM org.apache.coyote.http11.Http11Protocol init INFO: Initializing Coyote HTTP/1.1 on http-80 and there it stops. The port 80 is opened for listening but noone answers when you ring there. According to previous good starts, I should see another two lines just like those above, related to the port 443. Since the container hangs just before it should have printed them, I commented out the TLS-enabled connector and Tomcat started. What else can I say? The actual port numbers don't matter, I tried several with the same result. TLS worked perfectly before the crash and the configuration hasn't changed in between. It was Tomcat 5.0.25, I downloaded the fresh 5.0.28 and had the same result. I installed 5.0.28 on my workstation, copied the configuration files from the server and voila, everything works here. Now I have two identical installations, the same configuration, the same keystore, the same Java VM, and on the workstation I see it working, but on the server it hangs unless I disable the TLS connector in conf/server.xml. The weirdest thing is, this TLS connector has worked on that very server for several months now, since the 5.0.18 release. I don't know wether it matters, the server is a vServer, means it shares hardware with other virtual servers. It shouldn't matter though, because I allready had this configuration working there. Does anyone have any idea? Ciao, Igor Zlatkovic - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Taglib development - how to prevent EL expansion inside a custom tag
Hi folks! I have the following situation: In a given custom tag (a data-bound grid), I use several EL variables to allow to tag consumer to tailor the tag's output. While in Tomat 4.1 this was no issue - since the container didn't know nothing about EL, my tag took care of all EL parsing (using Commons EL). But now I got in trouble. Tomcat 5 parses all EL expressions it finds in a JSP page. This way I can't do it my own way. My question is: Is there a way to tell Jasper I don't way it to parse the EL expressions it finds *inside* my custom tag? Notice that I don't want to disable it for the whole page, so jsp-config is not suitable. I think this should be done at TLD or TagInfo level.

general question - Tomcat/Linux deployment
Hi, I have a question to people who have an experience with production level deployments of Tomcat based apps on Linux (preferrably RedHat). What are the best recommended combinations of Tomcat version - OS version (maybe with patches) - JVM version for deployment? Also, please share your related experience with WinNT/Win2000/WinXP. Thank you. Igor TN -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: help - Tomcat/Linux deployment
Yoav, thanks a lot for your response. Let me describe my situation more clear as I see it now. It's definitely not DBCP, DBCP works fine. This morning again the server was running but it couldn't serve my request. This time I copied the exception which I will paste later. The number of threads is not growing. There are 25 threads after the start and the amount stays the same. It still bothers me that 'ps' shows that each thread consumes about 6MB memory which seems to be too much but maybe that information is not really adequate. I'm trying to read the exception stack which I do not understand completely, but this is what it looks like to me: Http11 connector tries to pass the request to a service but cannot allocate a thread from a thread pool. Can anybody understand what really goes on and how to deal with it? Please take a look at the exception stack a couple of lines down. Thank you.

Re: help - tomcat/dbcp deployment
Well, to get DBCP working was not difficult at all. I just followed Tomcat how-to docs. And, as I learned from other people, it's being used on a production level. My Tomcat's version is 4.1.12. Thank you. Igor TN Hi, I developed a web-app consisting mostly of servlets and JSP, almost no static content. The application uses mysql and obtains connections from a dbcp connection pool. Now I'm deploying it for production on Linux (RedHat 7.2) in a tomcat standalone configuration. (Almost no static content, no cgi, no virtual hosts, no clustering, so I decided Apache httpd is not really needed.) It works pretty good for some time but ... The next morning the server is up and running but I can't obtain connection. When I'm trying to login into the app, the LoginServlet which is supposed to get a connection from the pool gives me an exception. Unfortunately, I can't show it here now, because I didn't copy it, and it will appear next time only tomorrow. But it reports something like Connection Failure, so it looks like a connection cannot be obtained from the pool. I'm quite positive that all my ResultSet's, Statement's and Connection's are closed in all appropriate places, and I'm also using 'removeAbandoned' in the server.xml descriptor. What can be the source of this problem? Also, immediately after my tomcat server is started, I lookup the running processes ( ps -ux ) and see that 25 JVM's is launched. Why so many? Is this normal? And what scares me is that all of those 25 JVM's are using 6% of memory each ( 25*6% 100% ! ). At least this is what the ps command shows. Can anybody shed some light on this? Is DBCP good for production? I configured it exactly as the Tomcat docs instruct. I will appreciate any comments and advices. Thank you.

help - Tomcat/Linux deployment
I was doing a development of the servlet/JSP web app on Windows and now I'm deploying it on Linux RedHat7.2 for production. The software used is Tomcat - MySQL - DBCP connection pool. On Windows my app is running fine but I have the following problem on Linux. The app runs stable all day long but next morning I can't login to my app, the exception says: 'Connection Failure'. Also, immediately after I start Tomcat on Linux I see a lot (26) of java processes running. As I understand, they are Tomcat internal threads launched as OS processes, because Linux JVMs (I tried both SUN's and IBM's) use green, not native threads. Now, as the time goes by, the number of these threads/processes grows, and when I try next morning to login, the server cannot create extra processes needed to fulfill the client's request, because on Linux/UNIX the number of user processes is limited. Can anybody tell me if I understand this right, and what might be a workaround? Thank you.

mod_jk, $TOMCAT_HOME/work directory and gigantic files
Hello,
Today i got a request from one of our developers to install Tomcat or
Solaris 7 machine running JDK1.2 and Apache 1.3.19
I compiled and installed mod_jk with no problems and installed binary
distribution of Tomcat 3.2.1
But then i found out that for some strange reason it can only process
Servlets out of webapps/examples directory,
and when i call any .jsp files it sits there and trying to contact the
server. At the mean time, while it is making an inpression of contacting
the server my $TOMCAT_HOME/work dramatically grows, so in 15 minutes or
me clicking the .jsp links it filled up my 580Mb partition..
So, i decided to look into that evil directory and see what is going on
there,
And what i found in 30Mb plain text file was pretty disturbing:
Thousands of these lines:

I can display those images as plain .html file but not in my JSP. Where is your JSP located ? On geocities.com or somewhere else ? They (like all free hosters) dont like hotlinking and dont send requested images if "Referer" isn't pointing to somewhere inside of geocities.com...
Re: problem with JSP displaying broken image link
My JSP is located on my own server (ISP is pacbell). The images are hosted by geocities. Do you pay for hosting on geocities ? If not then this is a hotlinking - you're trying to cheat them by stealing their traffic... So dont be surprised that images are not downloading - protection from such cheats is quite simple (using mod_rewrite).

Re: mod_jk does not compile (3.2b7)
I'm having the same problem on solaris(apache_1.3.14, gcc version 2.95.2 19991024 (release)) Any tips or pointers are greatly appreciated! I've tried everything mentioned on http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/mod_jk-howto.html I have also collected kernel trace - apxs tries execute "-o" ?!
