Connection/acceptCount Problem
I've mentioned this before in my Configuration e-mail, but it appears important enough for me to mention it again (as there hasn't been a response, and it is a pretty serious problem IMO). When I run tests at a high TPS, I might encounter a can't connect error (looks like I've reached the acceptCount limit). That's fine with me, so I stop the test and get ready to start another. When I start the next test (I usually wait a few seconds, let tomcat's CPU usage drop off), I immediately start getting can't connect errors, which should not be possible in the amount of time I'm getting them (TPS of 100, acceptCount 1000, that should be 10 seconds before I should get these errors, right?) My only fix for this problem is to shutdown and restart Tomcat, which is not really a solution. Is this a known problem or bug? Possible I misconfigured something?

RE: Configuration for High TPS
I plan to do pre-caching later. Currently my first test run is the unlucky user, which I'm calling a cold start and seeing how well it performs from a clear cache. No, I'm running TC stand-alone currently. Running it with Apache will improve performance? I'll look into it, but for now I'm running stand-alone. -Original Message- From: Durham David Cntr 805CSS/SCBE [mailto:[EMAIL PROTECTED]] Sent: Friday, August 09, 2002 11:32 AM To: Tomcat Users List Subject: RE: Configuration for High TPS Have you integrated Tomcat with another webserver for the static content, assuming you have some.

Tomcat 4.1.x JAASRealm Implementation
Hey All (Craig particularly)- Going through the code that exists in 4.1.8, I noticed that in the JAASRealm comments, Craig makes mention of using classes implementing the Principal interface to represent Users and Roles. This sounds like a good approach given the vagueness surrounding the JAAS implementation once you get into implementing it. In the JAASRealm class, there are setters for configuring the JAASRealm with the names of Principal classes that contain Users and Roles. After running a Find Usages with IDEA, I wasn't able to find any code which references these methods. So, how does the JAASRealm find out what classes contain users vs. roles? Is there some kind of magic going on with the realm config node in server.xml? I'd like to start using JAAS on Tomcat since we currently use JAAS for our JRun servers and converting the existing LoginModules won't be too much of a pain. jk -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Converting HOST to IP an IP to HOST
All right, but it does not solve my problem. I did a local web system that can be accessed both by IP or HOST. Depending on the way the user accessed( by HOST or IP ) the application I must display different contents. I could do this: if( request.getRequestURL().toString().equals(192.168.20.10) ) out.print(show IP content); else ou.print(show HOST content); But the web server has many network devices and the user can accesss the system from many other IP and HOSTs. The InetAddress.getByName() does not work with the machine network name only with inet hosts. Does anybody has any idea ???

RE: Configuration for High TPS
We ran some high TPS testing recently using a Sun 220R running Solaris 8. We were running an Apache/Tomcat combination using the mod_webapp connector. Just running a dumb simple servlet we were topping out at 165 tps and 80% CPU. We tried repeating the test using Tomcat standalone trying to figure out where the bottleneck was. We still topped out at 165 tps despite everything we tried to tweak. Our CPU was drastically reduced though to 40%. After running some e-mails through this list, the consensus was that we needed to tweak with our JVM as this was probably the cause of our ceiling. Not the web server configuration and not the horsepower on the machine. Actually, in standalone mode, we could not drive our CPU load beyond 40%. So far, we haven't had a chance to research this further and our production app is not pushing any limits just yet so its on the back burner. By the way, check how much stuff your Tomcat installation is logging. The default configuration is pretty verbose and this consumes large amounts of horsepower writing it all to disk. WinNT isn't overly good at walking and chewing gum and a lot of disk activity can drain resources pretty quickly. _ Mark Annal e-mail: [EMAIL PROTECTED] TARGUSinfo phone : (585) 598-7011 255 Woodcliff Drive fax : (585) 598-7001 Fairport, NY 14450 web : www.targusinfo.com _ -Original Message- From: Durham David Cntr 805CSS/SCBE [mailto:[EMAIL PROTECTED]] Sent: Friday, August 09, 2002 2:32 PM To: Tomcat Users List Subject: RE: Configuration for High TPS Have you integrated Tomcat with another webserver for the static content, assuming you have some.

I'd like to start using JAAS on Tomcat since we currently use JAAS for our JRun servers and converting the existing LoginModules won't be too much of a pain. As you've undoubtedly discovered, the JAAS spec doesn't provide any guidance for figuring out which Principal is which in the Subject that gets returned. Looking inside some of the existing implementations (such as the one that can access an NT domain), this was being done by hard coded instanceof checks on particular Principal subclasses. So, to generalize this a little, JAASRealm lets you declare the fully qualified class names of classes that represent your roles (in the roleClasses property). You can see it used in the createPrincipal() method inside JAASRealm, where it is checking the classname of each returned Principal against the list of class names you provided. When it finds a match, it assumes that principal.getName() on that Principal will return the role name that has been authorized for this user. The userClasses property serves a similar purpose for saying which classes actually represent the user. NOTE: The implementation classes themselves need to be visible to Catalina's internal class loaders for all of this to work. The simplest thing to do is put them in a JAR file in $CATALINA_HOME/server/lib, or as unpacked classes under $CATALINA_HOME/server/classes. NOTE: You won't see any direct references to the setRoleClasses() or setUserClasses() methods. The code that parses server.xml (the Digester module) has magic code (well, it's actually separately available in commons-beanutils :-) in it that matches up attributes in the XML elements to the corresponding property setters in the class. So, you configure one of these beasts like this: Realm className=org.apache.catalina.realm.JAASRealm roleClasses=com.foo.MyFirstRole,com.bar.MySecondRole ... / and the setter gets called for you via Java's introspection and reflection capabilities. jk Craig -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: Configuration for High TPS
Thanks Mark! That's some good advice. I haven't moved on to tweaking the JVM yet, I know there are some options I can use to increase performance, but I'm not to that point yet. I'm sticking with the standalone for simplicity. I'll likely turn this over to someone else, and the fewer parts, the better. We examined using Apache and JServ, and a coworker informed me the installation wasn't that straightforward. The logging tip is a good one, thanks! -Original Message- From: Mark Annal [mailto:[EMAIL PROTECTED]] Sent: Friday, August 09, 2002 11:58 AM To: Tomcat Users List Subject: RE: Configuration for High TPS We ran some high TPS testing recently using a Sun 220R running Solaris 8. We were running an Apache/Tomcat combination using the mod_webapp connector. Just running a dumb simple servlet we were topping out at 165 tps and 80% CPU. We tried repeating the test using Tomcat standalone trying to figure out where the bottleneck was. We still topped out at 165 tps despite everything we tried to tweak. Our CPU was drastically reduced though to 40%. After running some e-mails through this list, the consensus was that we needed to tweak with our JVM as this was probably the cause of our ceiling. Not the web server configuration and not the horsepower on the machine. Actually, in standalone mode, we could not drive our CPU load beyond 40%. So far, we haven't had a chance to research this further and our production app is not pushing any limits just yet so its on the back burner. By the way, check how much stuff your Tomcat installation is logging. The default configuration is pretty verbose and this consumes large amounts of horsepower writing it all to disk. WinNT isn't overly good at walking and chewing gum and a lot of disk activity can drain resources pretty quickly. _ Mark Annal e-mail: [EMAIL PROTECTED] TARGUSinfo phone : (585) 598-7011 255 Woodcliff Drive fax : (585) 598-7001 Fairport, NY 14450 web : www.targusinfo.com _ -Original Message- From: Durham David Cntr 805CSS/SCBE [mailto:[EMAIL PROTECTED]] Sent: Friday, August 09, 2002 2:32 PM To: Tomcat Users List Subject: RE: Configuration for High TPS Have you integrated Tomcat with another webserver for the static content, assuming you have some.

Subject: Precompiling JSPs for Tomcat
Hi all,
I'm having some issues with using Ant's jspc task (I have a
thread going
on the Ant mailing list), is there any way to manually call
the compilation
for Tomcat's build? Somehow, Tomcat must do it, so I figure
there has to be
a way to kluge something together that does the same thing?

RE: Converting HOST to IP an IP to HOST
Well, so far you've asked two different questions, yet they are supposed to be the same. Your first post wanted an IP address from a name, getByName() will do that for you, assuming by name you mean fully-qualified internet domain name. Now you are saying that the IP address will actually be in the URL, in which case you don't need to look it up, so it's not clear what you are trying to do. If you need to differentiate content based on whether someone accesses a resource by IP address or name, and there are many possible IP addresses, then all you have to do is test if the value returned from getRequestURI() has an IP address in it. So rather than look for a specific IP address, all you have to do is look for ANY IP address. That will tell you if someone entered the machine name or not. If you need something to translate a Microsoft WINS name (server name) to an IP address, you'll need some sort of Java WINS library...check google...my guess is the SAMBA group has written one (http://www.samba.org) but it may not be generally available.

FW: Re[2]: Apache 2.0.39 and Tomcat 4.1.8 Servlet issue
Ignacio, I was able to create a reproducible test case for you. It turns out this seems to be an Apache 2.0.39 issue only... Anyway, attached are two HTML files (copies of the Jakarta developer's guide). The first copy (Apache2TestShort.htm) is roughly 7k in size and displays without a problem. The second copy (Apache2TestLong.htm) is roughly 24k in size and doesn't display correctly. It gets cut off at 8192 bytes. I can reproduce this on my laptop (W2K Pro, P3) in both IE 5.5 and Navigator 4.75. On my tower (W2K Server, P4), I can reproduce on Navigator 4.79 only and it works in IE 5.5.

ant task to query if a particular app is running?
Hi, I'm wondering if it is possible to use one of the catalina ant manager tasks to query for the existence of a single running application. The closest thing to it that I can find is the List task. However, that just returns a string list of all running apps. What I would like to do is be able to make my install target check whether an app is already loaded. If so, instead of just saying already installed and ending the build, it would run the reload target. This would save timeor is it possible to catch some error condition from the install target and conditionally run the reload target if the install target returns that error condition? If so, how is that done? Note: I'm sending this mostly Ant question to the Tomcat-user list only because people like Craig know more about the manager app and the catalina tasks than the Ant people do. thanks, Jake -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: 500 error on all JSP pages
Hello all. I'm new to the list. I'm getting a 500 error on any JSP I try to run. If I run the servlet examples though, they seem to work fine. This is the same issue I have been working on all day. I finally got it to work about an hour ago. (FYI: I am running fresh install of Apache 1.3.22 and Tomcat 3.3.1 on Windows 2000 Pro. Apache is running as a service and using mod_jk to support Tomcat.) You are 80% home based on your description. Questions: - Does your jsp work if you throw it into the examples\jsp folder? If it runs in one folder but not another, make sure you have your directory layout formatted according this deployment guide: http://jakarta.apache.org/tomcat/tomcat-4.0-doc/appdev/deployment.html. - What does the Apache error log say? - What is your Apache-Tomcat glue (mod_jk, etc)?

jsp:forward
The saga continues. Downloaded Tomcat 4.0.4. Couldn't get it to work even with the examples. Desperate. Downloaded Tomcat 4.1.8. Worked with the forward (jsp/forward/forward.jsp)... a little hope. Moved my application over... after a little tinkering with the code, it worked. The interface with Forte is just a little funky as I can't compile directly from Forte.

RE: Servlet to JDBC connection
I don't know for sure, but in my experience the jdbc urls typically don't have the path on the disk referenced. Rather they usually have the database name listed, or no name (ie default database). So I'd check your docs for interbase and make sure that your url following the slash after the port is correct. Also, if your database is running on the same machine as the web server then consider using the loopback address instead of the the real ip address of the server. Sometimes that'll be more efficient. --mikej -=- mike jackson [EMAIL PROTECTED] -Original Message- From: Peter O [mailto:[EMAIL PROTECTED]] Sent: Friday, August 09, 2002 10:07 AM To: Tomcat Users List Subject: Servlet to JDBC connection What's wrong with this string?

What's involved w/ an upgrade of Tomcat from 3.1.1 to 3.3? Is this a fairly straight forward task, or is it quite involved? We're experiencing some odd behaviour from 3.1.1, and can't help but wonder if it's got something to do w/ the old version.

I click on a link from a main page and the link is like this http://mydomain/application/ (by default it will search for index.jsp) and the browser address bar will return somthing like below http://mydomain/application;jsessionid=42735B0A5AABE2DC6DA7212272E3CC3E with a Page not found error. but things will back to normal after I restart tomcat and clear cache again. Sometimes, I can just go back to the main page, refresh my browser and things will back to normal too without restarting tomcat. I can't figure out what is the cause as it is not happenning all the time. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Kris,
Did you find the code that refers to that path? Is it assuming that is
runs inside a webapp container? If so, sound like it might be a bug
(unless it was never intended to run standalone). I'd bet you could make
it work by messing with your classpath.

context problem with webapp connector
Tomcat 4.0.4 + Apache 1.3... I have setup the mod_webapp connector and it sort of works... However, I have a context in my tomcat server.xml file that looks like this: Context path=/tester docBase=tester debug=0 reloadable=false Parameter name=userdatadirectory value=/pathToData override=false / /Context Now, when I access my servlet directly into Tomcat standalone like this: http://URL:8080/tester/etc -- the parameter is passed to my application just fine. However, when I access my servlet through warp like this: http://URL/tester/etc -- the parameter doesn't get passed. I don't know why.. This is a stock Tomcat and Apache setup - the only thing I did was add mod_webapp and modify the apache configs according to the documentation. Other than the parameter passing not working, the webapp connector seems to work. -- that is: http://URL/examples/etc work fine. In a blind attempt to make it work, I added a hostcontext (same as above) /context/host to the warp connector section near the bottom of the Tomcat server.xml. That didn't seem to help any. Any ideas? Thanks Paul Phillips -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
unpacking of WAR
I worked on deploying my first webapp to another server today. I packaged it up as a war, transferred it to the other tomcat server, added the one line context element in the server.xml, and restarted. Nothing - the logs said that the webapp that was referenced by the context statement was not available or in a readable format. In fact, the war did not expand into the file system. So, I removed the context element, and restarted. With the context gone, the WAR expanded properly. Then I added the context back in, and it worked fine. Is this normal? Thanks Paul Phillips PS - the context element in the server.xml is just there to pass in a parameter containing the location of a data directory. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: Command line jspc throws NPE for page using JSTL
Hi Dave ;-),
I'm pretty sure it's meant to run standalone. The two normal ways I
know of are through the optional jspc Ant task or by running
%CATALINA_HOME%\bin\jspc.bat directly. Neither of those worked for me so
I went digging for some more detail about the failure. There's code in
the constructor of TagLibraryInfoImpl that strips a leading / off the
path before handing it off to JspCompilationContext.getResource which,
in turn, hands it off to JspCServletContext.getResource which explicitly
checks to see if the path starts with a /.

RE: RMI and TC4.x (Really classloader stuff)
Hi David: I'm in the same boat trying to use RMI and/or Jini from Tomcat. This isn't a complete answer to your question, as I'm still investigating the issue, but I'm posting what I know so far in the hope that it might help in your own solution, and also generate discussion that will guide my exploration. When all is said and done, if there's interest, I can post a Catalina-RMI HOWTO sort of document. Although I didn't try to run the test case that you attached to your bug report, I did take a look at it, and I think I know what's going on. Here's what I know so far (most of which you probably know already, but I'm summarizing for other folks on the list): When you pass an instance of some Serializable class as an argument to an RMI call (e.g. passing a command object, as in your test case), the RMI subsystem will serialize the object with an additional annotation indicating the locations from which the class's bytecode can be downloaded. When you pass an exported object (e.g. a server object or an object that will receive callbacks from remote objects), the RMI subsystem creates and serializes a proxy object (otherwise known as the RMI stub object) in place of the actual object. In either case, the remote RMI subsystem has to load the class that is called out in the serialized instance. It does this by calling the RMIClassLoader. The RMIClassLoader object first tries to find the class locally (i.e. in the default classloader). If it can't find it locally, it searches in the list of locations contained in the annotation mentioned above. If the required class is available locally, no further headaches are caused, which may be why some people have had no problems using RMI under Tomcat - they probably had the serialized classes and/or proxy classes in the standard classpath/classloader setup. And there we find our problem. (At this point you might want to have a look at the JSP snippet below) The annotation is determined by RMIClassLoader. According to the RMI and Object Serialization FAQ in the JDK1.31 API docs, If the _Stub class was loaded by an RMIClassLoader, then RMI already knows which codebase to use for its annotation. If the _Stub class was loaded from the CLASSPATH, then there is no obvious codebase, and RMI consults the java.rmi.server.codebase system property to find the codebase. If the system property is not set, then the stub is marshalled with a null codebase, which means that it cannot be used unless the client has a matching copy of the _Stub classfile in the client's CLASSPATH. If we're running a standalone application (and I believe also in Tomcat 3.x), we're using the system class loader, which has no obvious codebase, so the java.rmi.server.codebase property gets used. But what's the class loader used in Tomcat 4.x? I looked at the source code for Tomcat 4.0.1 (happens to be what I have on hand), and o.a.c.loader.WebAppClassLoader extends from o.a.c.loader.StandardClassLoader, which extends from java.net.URLClassLoader, which has a method called getURLs(). The WebAppClassLoader.getURLs() method returns a list of all the repositories it will search when trying to load a class on behalf of the web app. This list calls out all the jar's in WEB-INF/lib, common/lib, etc. Having not seen the source for RMIClassLoader, I suspect that the getClassAnnotation(..) method checks to see if the classloader for the supplied class is a URLClassLoader, and if so, uses the results of the getURLs() method call as an obvious codebase. This suspicion is supported by the last part of the JSP, where I create a classloader that extends from URLClassLoader but overrides getURLs() to return a phony url. The phony url shows up as the class's annotation. So the exact error you quoted in the bug report shows something about a protocol missing MalformedURL exception, which is caused by the fact that the urls to the repositories contain spaces, since the RMI annotation is supposed to be a space-separated list of URL's. Thus the annotation doesn't get parsed properly. This may be a bug in Catalina's class loader (i.e. should the returned urls have the spaces encoded to '%20'?) or possibly in the way RMIClassLoader uses the results of getURLs(). But it's not the problem. The problem is how to get our codebase into the annotation. Clearly the java.rmi.server.codebase property is not used, since the class loader has a codebase. But setting a system property doesn't feel right to me anyway, since in a webapp scenario, we're in a shared JVM, and we shouldn't be allowed to set system properties that will affect other webapps. (Aside- we similarly can't follow the normal practise of setting our own RMISecurityManager, again since it doesn't play nice with the other webapps. When I tried it, it seemed to screw-up Tomcat's internals, as well. We need to run Tomcat with security enabled, and set the appropriate
