Re: Client authentication with X509 certificate (Apache web server+mod_jk+Tomcat4.1.24) not working
Hello, What a relief!! And I've seen that the patch for this bug is a one-liner... I will try to backport it to the stock 4.1.24 we were willing to use. Do you have an idea of the approx. release date for 4.1.25? Thank you very much for your help. Antonio Fiol Bill Barker wrote: It's a known problem. See http://nagoya.apache.org/bugzilla/show_bug.cgi?id=15790 for more details. It is fixed in the CVS, and so will work in 4.1.25. Antonio Fiol Bonnín [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] Hello, I have been struggling with a strange problem: Using Apache Web server (1.3.23 - 1.3.26, not tested others). Using mod_jk (EAPI version, recent download). On a Linux machine. Using tomcat 4.1.24 Both on solaris and on Linux. When Apache is configured with SSLClientVerify optional or SSLClientVerify require Mod_jk is correctly configured (see why I say that later). Tomcat is configured with an AJP13 context, and responding well. PROBLEM: Client certificate cannot be obtained from the application. PROBLEM: In fact, there is an IOException *before* calling the servlet. PROBLEM: When tomcat is reconstructing the certificate. I get: Insufficient data ...or... too big WORKAROUND: I found that the same configuration on Tomcat 4.1.9 is working perfectly. I have been studying the differences between 4.1.9 and 4.1.24 and I have seen that certificate handling is done in very different places in the code (it has moved). Does anybody have an idea of what can have broken this? I am willing to submit a patch and/or do more investigation, so that this problem id fixed on 4.1.25 when it comes out.

RE: JNDI DataSource
Thanks Micheal. Actually, I did put the jar that contains the driver in $CATALINA_HOME/common/lib. So, I guess I'll just try what you recommended and if it works, then I think I'll switch to a different driver and test to see if this is a driver specific thing. Maybe no one tried that driver ever before.

Re: Need to restart tomcat very frequently
Paridhi Bansal typed the following on 13:25 14/06/2003 -0500 In our case,high no. of concurrent requests is not requireqd. no multithreading is being used at servlet end. So i have put maxProcessors in server.xml to 30..however, whenevr i start tomcat, it starts with 9 java threads that increase to 24 within seconds..WHY is this so? This is normal for Tomcat, which uses many threads for its operations; it gets a bunch ready to handle incoming requests, for example. It's not relevant to your problem. when i open the applicaions frequently, tomcat starts behaving erratically..no. of threads is ususlly b/w 28-29..sometimes i get the applet displaying the empty table but no data, sometimes i am not able to save the data...sometimes, tomcat gives socket exception..WHY does it behaves like this?On restarting tomcat, things start working fine... It's hard to guess what's wrong with your application, although it's most certainly due to your application's coding. Are you writing thread-safe code, i.e. being careful with class variables and static variables so multiple threads accessing the application at the same time aren't getting their data confused? Where are the socket exceptions coming from, there may be a problem with your database related code.

FormAuthenticator, Implementation question
The method authenticate() of the FormAuthenticator class does a redirect after getting the requestURI (savedRequestURL) (line 293). I don't understand why you just restore the request ( restoreRequest() ) without a redirect. // Redirect the user to the original request URI (which will cause // the original request to be restored) requestURI = savedRequestURL(session); if (debug = 1) log(Redirecting to original ' + requestURI + '); if (requestURI == null) hres.sendError(HttpServletResponse.SC_BAD_REQUEST, sm.getString(authenticator.formlogin)); else hres.sendRedirect(hres.encodeRedirectURL(requestURI)); return (false); *** BITTE BEACHTEN *** Diese Nachricht (wie auch allfällige Anhänge dazu) beinhaltet möglicherweise vertrauliche oder gesetzlich geschützte Daten oder Informationen.

imagine this situation
i have two jar files (pack1, and pack2) first is used from jsp ...
i've in pack1 f.e. one interface (MyInter) and one class (JarClassLoader extended
from ClassLoader)
pack1.jar i have defined as package headline;
in the second pack2.jar i have class (Hmmm) which implements interface from pack1
it look's like
import headline.*;
public class Hmmm implements MyInter {
...
...
...
}
i want to load class (Hmmm) that implemented class from pack2.jar (dynamicaly
by reading bytes from file and using defineClass)
i used for it JarClassLoader but it failed on defineClass with throwing
NoClassDefFoundError headline/MyInter not found

RE: JNDI DataSource
Hi everyone, I just managed to get this working. Obviously, it doesn't work if I put the Resource and Resource-params tags inside the GlobalNamingResources element, even if I create another Resource entry inside the Context element. Someone once mentioned that maybe the tag inside the Context element should be the Resource-ref tag, not the Context tag, but I really didn't know the syntax for this one, so I couldn't try it. Now, it works only if I put both the Resource and Resource-params tags inside the Context element of my application. I find this rather limiting, because most of the time, I don't wanna create a Context element for my application. I think there must be some other way to do this, but I guess I don't know it. The wierdest thing is, I DIDN'T need to add a Resource-ref element in my web.xml What's this entry for anyway? One other question I have is, do we have some sort of documentation or a DTD for this server.xml file that we check for available elements and their attributes. Thanks a lot for your help.

OFFTopic: Jsp vs velocity templates
Hi, I am wondering about the performance difference between Velocity templates and JSP. A test made by Rickard Öberg in Aug. 2001, was showing the difference being : JSP - 240-480ms Velocity - 50-70ms Since a lot has changed in tomcat and jsp. Has anyone any figures on what the difference is right now ? Is velocity still a lot faster ?

Re: OFFTopic: Jsp vs velocity templates
I have not run benchmarks (or use velocity) but velocity will probably still be faster. Velocity will run faster on tomcat 3 than tomcat 4 or 5. This is mainly due to constraints imposed by the servlet specification that extra checks need to be done as well as certain assumptions (don't ask can't remember) don't hold for servlet spec 2.2 vs 2.3 and 2.4. Of course since 2001, computers speeds have increased so running the same benchmark on a newer computer might skew the results. Since the introduction of JSTL (and better support for EL in JSP2.0) - I'd be curious to see rewritten pages(to reflect enhancements made to both display models) and a new benchmark. -Tim Reynir Hübner wrote: Hi, I am wondering about the performance difference between Velocity templates and JSP.

Singleton across multiple contexts
Hello, This question is probably not specific to Tomcat, but a Tomcat-specific answer could well suit my needs. I have an application which I have split in several different contexts.

Re: NoClassDefFoundError (error500) ... with external package
I'm guessing you have headlines.jar installed from:
http://sourceforge.net/projects/headlines/
Given the error:
root cause
javax.servlet.ServletException: net/sourceforge/headlines/Headline
Are you sure you don't have that anywhere Tomcat would be accessing it?

Re: Singleton across multiple contexts
Hi Antonio, - Extract the component into a separate JVM, and connect to it via socket. This is what I'd do, but I'd also write a client class to get access. I suppose you could use RMI or something, but I'm not familiar with that. Whatever you're comfortable with, I guess. You could also spin off this class in it's own thread inside one of your classloaders. That way it would shutdown and start up with the server (or maybe that's a drawback...) and you wouldn't have to add the overhead of another VM. - Extract the component into another context, and connect to it via HTTP. yuck. This isn't for locking or something is it? I get the feeling you're trying to use a class for storing or accessing something the way most people use a database...

Obviously, it doesn't work if I put the Resource and Resource-params tags inside the GlobalNamingResources element, even if I create another Resource entry inside the Context element. Someone once mentioned that maybe the tag inside the Context element should be the Resource-ref tag, not the Context tag, but I really didn't know the syntax for this one, so I couldn't try it. Now, it works only if I put both the Resource and Resource-params tags inside the Context element of my application. I find this rather limiting, because most of the time, I don't wanna create a Context element for my application. I think there must be some other way to do this, but I guess I don't know it. The wierdest thing is, I DIDN'T need to add a Resource-ref element in my web.xml What's this entry for anyway? One other question I have is, do we have some sort of documentation or a DTD for this server.xml file that we check for available elements and their attributes. Thanks a lot for your help.

My application includes a web interface to a kind of workflow system. This component is the workflow engine, which is in charge for automatic (background) state changes and actions. When my business/persistence logic changes a state, new potential tasks for this engine arise. So it has to be notified (=called) from any context that may change a state. The Tomcat user's list isn't the best place to discuss the design of your application, but it seems there's no good way to use a singleton across webapps. (Not that I searched the archives...) Also, I guess you are relying on method synchronization/instantiation to ensure that work gets done just once. That's one way of locking logic (the easiest) but -- as you know -- it falls apart when you use multiple classloaders. But there are other ways of locking, external file locks or maybe database bits you can use to keep tack of state and future actions. The only other thing I can suggest is to consider your options carefully before continuing. I don't have a clear understanding of what you've already designed, but I'd avoid doing something hackish like sockets inside Tomcat at pretty much any cost. If it can't be avoided, then I guess you write it and debug the snot out of it. Heck, I'd probably choose poll a queue table every three seconds before writing socket layers. :-) Anyway, you seem to know what you're doing, so good luck to you. -- Mike Johnson [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Embedding Tomcat with Java App and JRE only
Hi folks, I have read a article that explains how to embed the Tomcat with java app in O'Reily website. I will try to do it for my java app. But I want to do one step further which use JRE instead of JDK. Does anybody know if I pre-compile all jsp files, is it possible to embed the Tomcat with JRE only? Thanks!

Re: Tomcat classpath not set at boot
I've done some more testing and it doesn't have anything to do with starting Tomcat at boot as I first thought. The problem is that my servlet tries to connect to the X server when run. I have no idea why it needs to connect to the X server (It's a servlet that EspressReport wrote to connect to a database and generate a report.), but anyway this seems to be the problem. In order to get my servlet to work I need to do 'xhost + localhost' before Tomcat is started. I'm starting Tomcat as root and root is not allowed to connect to screen :0 by default since my user name owns it. I think if I started Tomcat with my user name and not root it would work, however, for some reason I can't start Tomcat this way. When I start Tomcat as a normal user it starts fine and ps -ef shows the java processes started by Tomcat, but after about 3 seconds all the processes quit and Tomcat is no longer running.

Re: Singleton across multiple contexts
Place the jar (or class) in common/lib (or common/classes) and all will be ok.

Re: Need to restart tomcat very frequently
Hi!! Thanx for the reply..Actually In my case, though it's a web-based application but it's still at testing stage..there's max 1 user at a time..so there's no question of multiple threads accesing the code at atime..moreover, the servlet too just has a single thread for processing.. besides this, the application works fine most of the time,...it's only some times when i keep on closing and opening the application again and again, or when it's kept open for very long, things go wrong..at this time, when i try to shutdown tomcat, then also it gives netsocket exception..i have to forcefully shut it down using killall java and then restart it..Restarting tomcat makes thing start working fine again.. Paridhi - Original Message - From: Kief Morris [EMAIL PROTECTED] Date: Sun, 15 Jun 2003 12:58:09 +0100 To: Tomcat Users List [EMAIL PROTECTED] Subject: Re: Need to restart tomcat very frequently Paridhi Bansal typed the following on 13:25 14/06/2003 -0500 In our case,high no. of concurrent requests is not requireqd. no multithreading is being used at servlet end. So i have put maxProcessors in server.xml to 30..however, whenevr i start tomcat, it starts with 9 java threads that increase to 24 within seconds..WHY is this so? This is normal for Tomcat, which uses many threads for its operations; it gets a bunch ready to handle incoming requests, for example. It's not relevant to your problem. when i open the applicaions frequently, tomcat starts behaving erratically..no. of threads is ususlly b/w 28-29..sometimes i get the applet displaying the empty table but no data, sometimes i am not able to save the data...sometimes, tomcat gives socket exception..WHY does it behaves like this?On restarting tomcat, things start working fine... It's hard to guess what's wrong with your application, although it's most certainly due to your application's coding. Are you writing thread-safe code, i.e. being careful with class variables and static variables so multiple threads accessing the application at the same time aren't getting their data confused? Where are the socket exceptions coming from, there may be a problem with your database related code.

Re: java.lang.reflect.InvocationTargetException
java.lang.reflect.InvocationTargetExceptionThe keystore needs to be the full path to the keystore. In your case you need something like keystore=c:\documents and settings\798454\.keystore.
