source for JDBCRealm?
I've been looking around the Apache/Jakarta site, and I can't find the Realm-related stuff (I understand it's separate from Tomcat). We're running Tomcat 4, and I'd like to hack the query JDBCRealm sends to Oracle so username checks are not case insensitive. Btw, which JAR in my Tomcat directories is related to JDBCRealm?

case sensitivity with JDBCRealm
Here's our server.xml's Realm element: Realm className=org.apache.catalina.realm.JDBCRealm debug=99 driverName=oracle.jdbc.driver.OracleDriver connectionURL=jdbc:oracle:thin:@192.168.1.144:1523:orcl connectionName=scott connectionPassword=tiger userTable=users userNameCol=username userCredCol=password userRoleTable=roles roleNameCol=role / Basically out of the textbook...but the problem is, we're moving from MySQL to Oracle, and the MySQL database wasn't case sensitive when checking the username. Is there any way to turn off case sensitivity on the JDBCRealm side of things when checking the username in the Oracle database?

certificate question for 2 domains pointing to same website
Right now, we have one domain that goes to our web application, and we want to another new domain to point to the same web app (it already does). Naturally, if you access the site via the new domain, it tells the browser that the certificate issued by the site doesn't match the name of the site, so we're looking into getting an additional certificate. If we do this and get that new certificate into the keystore used by our Tomcat 4, will everything be fine, or will Tomcat present 2 certificates to users accessing the site? I mean, will it correctly present the certificate for the old domain to the user when they go to the old domain, and the new certificate to those entering via the new domain?

Re: AW: certificate question for 2 domains pointing to same website
Wait a second...Tomcat will determine which cert to send down based upon the IP address that the browser went to? I guess that makes sense...so does the web server never get to see what domain the browser was looking up to come to the site, or is that info available? I'm just trying to figure out if there's a way to run the website for a limited time with 2 domains and 2 certs--I mean, the 2 domains, each with their own cert, but with one single public IP address. We have a bigIP load balancer in front of our Tomcat servers...so do our Tomcat servers still see the public IP address that was used to reach them? I ask because those boxes only have private IPs, and the load balancer has the only public IP. If there's no way to do it, then I guess we just arbitrarily switch at some point and don't worry about the people using the old domain seeing invalid certificate messages... - Original message - From: Steffen Heil [EMAIL PROTECTED] To: 'Tomcat Users List' tomcat-user@jakarta.apache.org Date: Sat, 5 Feb 2005 01:26:00 +0100 Subject: AW: certificate question for 2 domains pointing to same website Hi If we do this and get that new certificate into the keystore used by our Tomcat 4, will everything be fine, or will Tomcat present 2 certificates to users accessing the site?

Emergency: make Tomcat forward
I have Tomcat 4.1.27 on a Linux box at a particular public IP address, and I want to make it forward ALL requests to a Tomcat on a Windows box at another public IP address. Over the weekend, we changed the DNS to the Linux box, but now we need to roll back to the Windows box, and we already changed the DNS through our ISP, and a lot of folks are hitting the Windows box, but some people are still hitting the Linux one. So, we want to turn on the Tomcat on the Linux box and somehow send all those folks to the Windows one.

Does JDBCRealm close connections?
Hey there--just wondering if JDBCRealm with Tomcat 4 ever closes connections it opens...I'm assuming it can open up more than one connection to the database if traffic gets heavy (because we think we're seeing that, though it's hard to tell for sure). If so, when does it go about closing those connections? I was reading about it here: http://jakarta.apache.org/tomcat/tomcat-4.0-doc/realm-howto.html#JDBCRealm We're trying to debug a nasty problem, and we're wondering if a couple hundred folks try to log in at the same time and there are only about that many database connections that can be pooled (and a bunch of the db connections are already in use by the web app), then does JDBCRealm just keep opening up more and more connections to the database?

how many connections can tomcat handle?
We're running Tomcat 4.1.27 on a pretty up-to-date Red Hat 8. I'm wondering what usually determines the number of connections Tomcat can handle. Would it typically be Tomcat breaking first, or just the server itself trying to deal with so many connections?

Tomcat 4 doesn't start http service on Linux?
We just installed Tomcat 4 on 2 Red Hat servers, and we have a BigIP load balancer in front of them. In troubleshooting an issue, the guy working with our BigIP said that when he was running Apache on either of the Linux servers, the load balancer could tell that the http service was running, but when Tomcat was running, it didn't know what to check for on a service level, so in the end, they had to set it up to just do a TCP check to see if the port was open. He says this isn't ideal since the port being open doesn't mean the service is up (meaning Tomcat). He thinks that Tomcat should start up the http service (I guess he means httpd) when it starts--that maybe I just need to look around in Tomcat's configuration for the place to set this, but I'm not so sure that this is the case. In a nutshell: is Tomcat supposed to start up the http service or something similar to what BigIP is looking for from Apache?

question on session info in manager webapp

load balance with tomcat
We're trying to install our existing web app on multiple machines and put a BigIP load balancer in front of them. Do we need to do anything different with Tomcat and/or our web app to get this load balancing to work, or should we basically be able to copy the Tomcat directory onto each machine and go? The reason I ask is because if we access each web server directly via a public IP address, we can use the web app. However, if we try to go through the BigIP's public address, it won't work (and we're trying to figure out why).

what to do about port for Tomcat 4 on Linux?
I want to move to Tomcat 5 right now, but can't yet, and for the time being we need to move from Tomcat 4.1.23 on Windows to 4.1.31 on Red Hat, so I'm now facing a question of what to do about the port Tomcat runs on. I've read stuff online that suggests it's best to leave it at 8080 since 80 is a privileged port on *nix. But from that point, I'm not sure what the best practice would be, though I've read different options, like user space port forwarding, kernal space port forwarding, or using a port forwarder (portfwd or redir4a), none of which I'm familiar with. What do you Tomcat users suggest would be a good approach for someone who's only a beginner/intermediate with Linux and using standalone Tomcat? In case it matters, note that we are also moving from our single Windows web server to 2 Linux web servers (each running standalone Tomcat), and we're trying to configure a load balancer hardware appliance in front of the two web servers.

memory problem?
We often have to restart Tomcat because of an ODBC issue (yes, we're switching databases as soon as we can). However, I've noticed this error occuring in the Windows 2000 Event Log in association with Apache Tomcat: The CreateThread function failed for the following reason: Not enough storage is available to process this command. . It can show up a few times per day, or only every once in a while. From what I can tell by Googling around, this error message might actually have to do with us running out of system memory! However, I'm not certain, so I'm wondering if this means that Tomcat/JVM is running out of memory, or Windows is (in which case Tomcat would too, of course). In either case, does does this mean we need to move to clustering or whatever? The machine has about 3GB of RAM and the JVM gets half of that allocated to it.

is tomcat failing?
We're using Tomcat 4.1.27 and we have a main database that the web app uses most of the time, and then a small MySQL database that Tomcat is configured to use for basic authentication. We used to have trouble with the main db hanging up on us, so we had a little watch program running to restart Tomcat to reset the db connections whenever it could no longer open a JSP that performed some minor db access, but now we've resolved that problem. However, Tomcat still hangs on us (albeit less frequently), and now we're wondering if this issue is completely different. Could MySQL be hanging on us, or is it Tomcat? For a while we've been thinking it was MySQL, but couldn't test it very easily. Today, I was browsing the site, and all of a sudden some images stopped loading (only some, not all), and some of the text sizes were weird, meaning it seemed like the stylesheet wasn't loading. Right after this, our site went down as it does a few times every day, and we had to restart Tomcat. Often when we have to restart it, we have to restart it again a short time later (during peak time). Any ideas as to what's going on here? Thanks, Stephen P.S. I decided to play with Tomcat 5 a few months ago, but got annoyed at all the changes necessary to reconfigure our web app, so I put it aside without finishing it. Do we need that, or just a later version of Tomcat 4, or what? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

website going down
We had a problem where our website would hang because Tomcat couldn't access the main database over DSN (on another machine), and it was a problem with our vendor's ODBC driver, so we moved to the Linux version (which was more stable). We had created a Watchdog program that would call a JSP with simple database access, and it would restart Tomcat whenever the problem occurred (although that sometimes wasn't sufficient--sometimes we would also have to go in and manually restart the ODBC driver). Anyway, our problems have lightened considerably, and consequently our watchdog program doesn't have to do much, although from once in a while it does restart Tomcat for us. However, we are now seeing a new problem. The watchdog program will keep going along as if there's no problem, and yet the website will be hanging! Because there was a problem in the early days of development with using the main database for the basic authentication used to enter our website, we set up a MySQL database on the same machine as Tomcat and have it access that small database locally by telling it to use JDBCRealm in our server.xml file. The watchdog program doesn't access a secure JSP, so it doesn't really have to log in. In other words, as far as I can see, Tomcat must be trying to go to MySQL to pop up that basic authentication box, but the box never pops up because I suppose MySQL is hanging for some reason. Generally all we have to do is restart Tomcat to get everything back to normal. My question is, do you know of any reason why MySQL would be doing this?

DBCP connection pooling by default?

I found the following in our server.xml and am wondering if this means we are definitely using this Commons DBCP: - !-- Define the top level container in our container hierarchy -- - Engine name=Standalone defaultHost=localhost debug=0 - DefaultContext crossContext=true Resource name=jdbc/myResource auth=Container type=javax.sql.DataSource / - ResourceParams name=jdbc/myResource - parameter namefactory/name valueorg.apache.commons.dbcp.BasicDataSourceFactory/value /parameter I think we are NOT using it because we have some Java classes that are intended to handle connection pooling, and they look similar to some of the textbook ones floating around online. I'm just wondering if there would be connection pooling in place with the above XML if we didn't somehow override that with our own connection pooling classes.

installing tomcat 4.1.27 on linux

Re: installing tomcat 4.1.27 on linux
Sounds good to me! Usually when we move Tomcat to a new Windows machine, we just use that same executable zip (jakarta-tomcat-4.1.27.exe) to install Tomcat on the new machine, and then copy over our directories from the original machine to replace the Tomcat directory that got created. I know this might be a really dumb question, but will that .exe file run and install everything on the Linux box, or will I have to use jakarta-tomcat-4.1.27.zip and extract everything? It's all slowly and hazily making sense...I hope...on Red Hat I won't have to install it quite as much as Windows which needs to put things into the registries, etc, right? So I just extract it and put some kind of symbolic link to the Tomcat executable in usr/local/bin or something like that, huh? But will that be enough to mimic the functionality we usually have, since typically on Windows we run it as a service? Sorry for my rambling... - Original message - From: Robert F.

We've been allocating 1GB to the JVM when installing Tomcat as a service, but now we'd like to do 2GB, so I just changed the two instances of 1024 to 2048 in this: The short answer is you can't do that. The long answer is, as usual, a bit more complicated. First, Windows normally splits the 4GB virtual space into 2GB for each user process, and 2GB for the operating system, shared across all processes. There is an option for Windows Server bootstrap to change this boundary to 3GB for user processes and 1GB for the OS (sorry, I don't remember the tag). Second, the virtual space that Windows gives each user process is fragmented by DLLs scattered around in it, and the Sun JVM insists on having one contiguous area for its heap (at least it did in 1.4.1; have not verified this in 1.4.2). This makes it difficult to get a whole lot more than 1GB for the heap. Third, there is (or possibly was) a bug in the JVM heap initialization that failed to treat the specified sizes as unsigned, so 2GB and above was treated as negative. Lots of weird results from that. Again, I haven't looked in the 1.4.2 code, so this may have been fixed by now. Your best bet is to do a binary search with -Xms/-Xmx and see what your environment will handle. You don't need to do this with Tomcat - just specifying -version will suffice. (Just make sure you put the heap settings before -version, because anything on the command line after -version is ignored.) - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: 1067 error when starting service after allocating more memory to JVM
Thanks, you've been a big help. 1536m worked for me.

Sounds like you're not that familiar with JVM execution, so you might want to brush up on that aspect using some of the online tutorials on the Sun web site (and other places). The tomcat.exe executable is used when running Tomcat as a Windows service, and then only as a launcher for the JVM; Tomcat itself is pure Java, and you can run it as a regular Java program, if need be. (It's a lot easier to test things out that way.) In any event, all I'm suggesting you do is try something like the following, from a command prompt: java -Xms1024m -Xmx1024m -version java -Xms1536m -Xmx1536m -version java -Xms1280m -Xmx1280m -version (etc.) where you're varying the heap sizes in powers of two increments trying to find the largest values that will work on your server. (I'm assuming the 2nd example above will fail - it does on my XP boxes, but works on my Win2K one.) Use -version, since that is the fastest way in and out of the JVM (no program need be executed). Once you've found the maximum heap size that can be allocated, you can use that for your Tomcat environment. (You may have to reduce it a little since Windows needs space in the process virtual memory for such things as a stack for each thread, and Tomcat can kick off a lot of threads.) Whether you want to keep the minimum and maximum the same depends a lot on your workload; larger heap sizes take longer to garbage collect, so you may want the default lower to reduce delay time during not-so-busy periods. You should really size your heap on what you actually need at times of peak load. Setting it to the maximum possible is not always the best for server responsiveness. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

RE: session listener not listening
One other thing: most of our web app's Java classes are put into a
single JAR file in JBuilder that we then dump into Tomcat's common\lib
directory. However, we have to put our servlets individually into
Tomcat's common\classes directory. My session listener class gets
compiled into the JAR file with all of the other classes in that central
package (see below), so I was wondering if perhaps this session listener
class needed to be dropped individually into the same place as where the
servlets go, and I've tried that (I've even tried making sure the class
was also dropped into a directory in common\lib\central in case that's
what it needed). However, this still isn't working for me! At least,
sessionCreated and sessionDestroyed never seem to be called, according
to my print statements (and the static methods they call don't seem to
be updating my session HashMap).

session timeout: web.xml and setMaxInactiveInterval(int)
My web.xml has the following: session-config session-timeout30/session-timeout /session-config However, when a user logs in, the following code in our app gets executed: HttpSession session = request.getSession(false); session.setMaxInactiveInterval(7200); I've been fiddling with the web.xml and didn't realize that other code was in there, and I'm wondering who trumps who. I would assume that the web.xml's global setting would have priority over any individual setting, but it could easily be the other way around!

session listener not listening
My session listener doesn't seem to be listening. At the top of my
web.xml (before any servlet elements, and I have nothing like a filter
or anything else before it), I have this:
listener
listener-classcentral.OurSessionListener/listener-class
/listener
Here is my listener class:
package central;
import java.util.HashMap;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;
import wwxchange.utility.*;
import wwxchange.beans.*;
public class OurSessionListener implements HttpSessionListener {
public void sessionCreated(HttpSessionEvent se) {
HttpSession session = se.getSession();
UserAcctBean user = (UserAcctBean)
session.getAttribute(currentuser);
String loginID = user.getLoginID();
System.out.println(Added session: + session.getId() + for user
+ user.getLoginID());
SystemControl.addActiveUser(session.getId(), user.getLoginID() );
}
public void sessionDestroyed(HttpSessionEvent se) {
HttpSession session = se.getSession();
SystemControl.removeActiveUser(session.getId());
System.out.println(Removed session: + session.getId());
}
}
My SystemControl's static HashMap doesn't seem to be getting updated,
and the above methods aren't even getting called because nothing is
going to stdout when I log in as different users.
What am I doing wrong? Is my listener not registered to listen?
Thanks,
Stephen

manager app: sessions
I have read the Manager App HOW-TO at http://jakarta.apache.org/tomcat/tomcat-4.0-doc/manager-howto.html So, I'm accessing the following URL just like the example shows: https://www.(mydomain).com/manager/sessions?path=/ristmain I'm trying to interpret these results: OK - Session information for application at context path /ristmain Default maximum session inactive interval 30 minutes 30 - 40 minutes:100 sessions 120 - 130 minutes:1071 sessions My main question is, does Tomcat update these numbers in realtime, or only once in a while (like every 10 minutes)? I'm wondering why it says 30 - 40 minutes...? I logged into the web app as another user and that 100 didn't increase. It's hard for me to tell if my logging in was counted later on just because real users are logging in and out all the time. I guess the most important thing I need to know here is how long I should wait to take another sampling...wait 10 minutes each time, or what? If it says 100 sessions, then that means within the past half an hour (or 40 minutes?), there have been a total of about 100 users logged in, right? Are these the only statistics available about sessions? Would I have to customize Tomcat to find out more?

Re: manager app: sessions
What? I can only find out how many sessions have been active for 30 to 40 minutes and 120 to 130 minutes? That doesn't seem to make sense. I understand if Tomcat doesn't want to update the stats too frequently, but what about stats on sessions logged in more than 40 minutes and less than 2 hours? Why would it arbitrarily jump up to 2 hours? And how likely is it that I have only 100 users who have been active for a total of exactly 30 to 40 minutes, but 1071 users who have been active for over 2 hours? If my timeout is set to 30 minutes, then that means they have to keep browsing the site at least every 30 minutes to avoid getting timed out. So is what you're saying right? 30 - 40 minutes:100 sessions 120 - 130 minutes:1071 sessions I mainly need to know about how many sessions are currently open. I thought that first line meant that about 100 sessions have been opened in the past half hour, give or take 10 minutes.

But the first row tells you about sessions that have been alive between 30 and 40 minutes. You logged in but your session was active *way* under the 30 minute lower limit for the stats one line 1.

session and connection timeouts
Hello everyone, we're running Tomcat 4.1.27 and my conf/web.xml has a session-timeout of 30, which I understand should override the default 20 minutes. I'm wondering if it actually does, because I see here that someone is saying there's a bug in Tomcat 4 so that sessions always time out after 20 minutes: http://listarchive.cinjug.org/html/users/2004-06/msg9.html My main question is how Tomcat reacts if more and more sessions are opened such that the memory allocated to the JVM gets close to the max--does Tomcat crash/restart, or should it begin expiring the oldest sessions in order to recover memory (even though they might be younger than 20 minutes or whatever the timeout value is)? As for our issue with connection timeouts, we recently bumped it up to 12 in order to make sure large file uploads don't fail (usually less than 1 MB and often less than 500 KB), but I'm wondering if that's a bit excessive even for users on dial-up connections...

how many sessions in use?
Is there any way to find out how many sessions are currently in use? I'm ultimately trying to get at how much memory is being used per session...if there's no way to really get at this without a profiler tool, do any of you use a particular one with Tomcat applications? JFluid, JProbe, etc? Thanks! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
basic authentication or not?
In a nutshell, I'm wondering if it's better NOT to use basic authentication. We have over 10,000 regular users, and I think it would be good for us to move to a more standard login page instead of that authentication box that pops up. My question is, would we have to change a lot to do this? At the moment, I'm not even sure we're using basic authentication, and below I will outline my attempt to determine if we're even using it... When you type the URL to our website, it pops up an authentication box before it shows you anything else and you must get past that to get into the web app. As far as I understand (the original developer is no longer with us), we are using basic authentication with Tomcat 4. However, I was perusing this document to figure out where our basic authentication is configured and it doesn't look like we have all this stuff: http://www.jguru.com/faq/view.jsp?EID=1131436 Notable exceptions are any security-constraint or login-config nodes in our web.xml, and since the example on the jguru page put BASIC in the login-config node, I'm really not sure that we're using basic authentication (although that's still my gut feeling). In our server.xml, I see that both of the following are uncommented, but I'm guessing that only the second one is being used since I don't think we have anything (no JNDI) set up for the first one: Realm className=org.apache.catalina.realm.UserDatabaseRealm debug=0 resourceName=UserDatabase / Realm className=org.apache.catalina.realm.JDBCRealm debug=99 driverName=org.gjt.mm.mysql.Driver connectionURL=jdbc:mysql://127.0.0.1/mainDB connectionName=user connectionPassword=pass userTable=users userNameCol=Username userCredCol=Password userRoleTable=roles roleNameCol=Role / Aside the big database used by our web application, we have a small MySQL database whose sole purpose is to authenticate users. Would it be just as simple to continue using that for authentication if we moved away from this popup box authentication? Is there any good reason to have this authentication database outside of our main database? Or is this somehow protecting our web app more--making you authenticate before you ever communicate with anything in our site (e.g. a LoginServlet or something like that). I know this is long...I appreciate any feedback, though! Thanks, Stephen - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: basic authentication or not?
Duh. I was looking in the general Tomcat web.xml--yes, in my app-specific one, we're using BASIC authentication. Ok, so Tomcat knows to use the additional MySQL database for authentication. Right now, if you go to www.ourDomain.com it'll make you authenticate and then it will forward you to the default web application at www.ourDomain.com/DefaultApp/Welcome.jsp, and we have several web apps and you can cross from one to the other without authenticating, so you could go up and modify the URL to www.ourDomain.com/OtherApp/index.jsp and you'd be there instantly. So my question is, if we changed to form-based authentication so we could present our look and feel from the start, would it work for authenticating all the web apps if the login page was under a particular web app's folder? In other words, where would and could we stick a Login.jsp that would be presented to the user when you type www.ourDomain.com?

how to show System Unavailable page when Tomcat is down
Though I'm capable of adding to the JSPs and servlets on an existing site, I'm no web server guru, so I'm having a hard time with this problem. Our database vendor's ODBC driver has issues, so occasionally we have to restart Tomcat (and maybe the driver) to get the website running again, and since this is used by thousands of people every day, they can get pretty annoyed when all they see in their browser is Page cannot be displayed (and this can go on for anywhere from 5-15 minutes). We need a way to show some redirect requests for the website to some static HTML page when Tomcat is down. Since Tomcat is running our website, I'm really not sure of how to provide a solution for that (we don't have multiple application servers--just one web server and one database server).

Re: how to show System Unavailable page when Tomcat is down
If we currently have Tomcat 4 running on Win 2000, would there be significant overhead to run Apache as well just so that we can put up an error page when Tomcat has to be restarted? Some of you mentioned I should try using a type 4 driver, and I Googled around to brush up on different types, and I realize we probably use a type 1 driver since it's a JDBC to ODBC bridge. The database we're using is Raining Data's D3 database (a multivalue db), and I searched around and only found a couple of JDBC drivers that look like they might work, but they're type 3 drivers, and I'm wondering what (if any) additional layer I need to make a type 3 driver talk to the D3 database, or if I can simply drop it into my J2EE/Tomcat. These are the drivers I found: FusionWare, halfway down the page: http://www.sqlsummit.com/JDBCVend.htm Liberty JDBC: http://www.multivalue.com/LibJDBC.html - Original message - From: David Smith [EMAIL PROTECTED] To: Tomcat Users List [EMAIL PROTECTED] Date: Mon, 14 Jun 2004 20:10:11 -0400 Subject: Re: how to show System Unavailable page when Tomcat is down To directly answer your question, essentially something has to be listening on port 80 even when Tomcat is down. The only way I know of to do that is to put up some kind of proxy server with a error page. I know Apache can be used that way, Squid looks like it could as well. On the other hand, you could also replace your ODBC driver with a genuine type 4 driver and make your site much more reliable.

Re: emergency - need to get into admin app
Thanks to everyone who wrote back with suggestions. We had a rough time, and right now we're up because we slapped the old drives back in. After doing that, I found CATALINA_OPTS in the Environment Variables, and it had the -Xms and -Xmx flags after the -server one, but I called the guy who originally set everything up for us over a year ago, and he said he remembered that that didn't work him (we're on Win 2000 Server) and he had to set the memory via some super long command line when installing tomcat as a Service.

For example the X flag controls memory, so if your app requires it you can instruct tomcat to launch JVMs with a higher max (i.e. if it seems to be running out of memory). As an example I use: -Xmx128m to set the max at 128MB (i think the default is 64?) Note I'm using this under linux so it's in a shell script.

quick question when getting started
I'm upgrading from Tomcat 4 to 5 and I just installed Tomcat 5 on a dev machine to play with it, and I know a couple things are organized a bit differently, but the provided index page is weirding me out. I tried to add a line of text to the index.jsp in webapps\ROOT and when I reload the page (that I browse to by going to localhost on my Win 2K Server machine), that line of text isn't appearing. I've tried adding other bits, too, and I've tried restarting Tomcat, and I found a catalina-root.jar in the WEB-INF\lib folder and deleted that in an effort to get it to recompile the index.jsp, but nothing seems to be working! Why? Here's an example of what I've modified in the HTML: pcenterbIf you're seeing this page via a web browser, it means Stephen has setup Tomcat successfully. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
ZipFileException: can't access localhost anymore
Our small company has been using Tomcat 4 for over a year to run our web app, and on 8/15/2003 I downloaded Tomcat 4.1.27 to install on this development machine, and I haven't had to think much about it since, and I'm not super familiar with Tomcat. About all I do with it is stop and restart the service to load up changes I add to the site. Well, today it just isn't working. Usually I access the site on my machine by just typing localhost or http://localhost/ in IE 6, but it's just giving me a page cannot be displayed error. I'm perusing the Jakarta docs and guides at OnJava and other places, but I figure I could spend all day (or several days) on this, and I need to get my work done! What I need is a good idea of exactly what I can do to find and correct this problem. I have no idea what this is about or why it would suddenly have become a problem, but here's what's in my stdout: Bootstrap: Create Catalina server Bootstrap: Class loader creation threw exception java.lang.IllegalArgumentException: addRepositoryInternal: java.util.zip.ZipException: error in opening zip file at org.apache.catalina.loader.StandardClassLoader.addRepositoryInternal(StandardClassLoader.java:1110) at org.apache.catalina.loader.StandardClassLoader.init(StandardClassLoader.java:200) at org.apache.catalina.startup.ClassLoaderFactory.createClassLoader(ClassLoaderFactory.java:202) at org.apache.catalina.startup.BootstrapService.init(BootstrapService.java:163) at org.apache.catalina.startup.BootstrapService.main(BootstrapService.java:297) And here's my stderr: java.util.zip.ZipException: error in opening zip file at java.util.zip.ZipFile.open(Native Method) at java.util.zip.ZipFile.init(ZipFile.java:112) at java.util.jar.JarFile.init(JarFile.java:127) at java.util.jar.JarFile.init(JarFile.java:65) at org.apache.catalina.loader.StandardClassLoader.addRepositoryInternal(StandardClassLoader.java:1082) at org.apache.catalina.loader.StandardClassLoader.init(StandardClassLoader.java:200) at org.apache.catalina.startup.ClassLoaderFactory.createClassLoader(ClassLoaderFactory.java:202) at org.apache.catalina.startup.BootstrapService.init(BootstrapService.java:163) at org.apache.catalina.startup.BootstrapService.main(BootstrapService.java:297) java.lang.NullPointerException at org.apache.catalina.startup.BootstrapService.init(BootstrapService.java:198) at org.apache.catalina.startup.BootstrapService.main(BootstrapService.java:297) And in case this helps, here's what I have in my conf\server.xml file for the connectors: - !-- Define a non-SSL Coyote HTTP/1.1 Connector on port 80 -- Connector className=org.apache.coyote.tomcat4.CoyoteConnector port=80 minProcessors=50 maxProcessors=100 enableLookups=true redirectPort=8443 acceptCount=100 debug=0 connectionTimeout=2 useURIValidationHack=false disableUploadTimeout=true / - !-- Note : To disable connection timeouts, set connectionTimeout value to -1 -- - !-- Define a SSL Coyote HTTP/1.1 Connector on port 443 -- - Connector className=org.apache.coyote.tomcat4.CoyoteConnector port=443 minProcessors=100 maxProcessors=2000 enableLookups=true acceptCount=100 debug=0 scheme=https secure=true useURIValidationHack=false disableUploadTimeout=true Factory className=org.apache.coyote.tomcat4.CoyoteServerSocketFactory clientAuth=false protocol=TLS keystorePass=w0rldw1d3 keystoreFile=c:\Tomcat\keystore.ksf / /Connector Thanks for any help!

Re: ZipFileException: can't access localhost anymore
I've resolved this issue. We build a JAR file in JBuilder that contains all the JavaBeans, etc, and we stick that in Tomcat's common\lib, and I checked it and somehow it had 0 KB! Weird. So I just copied it over again and I no longer get that ZipException when starting up Tomcat. It was like Tomcat overwrote the JAR file by accident or something. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
refreshing what tomcat has in memory
I have a copy of Tomcat both on my dev machine and my production machine.
I have some code that looks for an image in a given location, and on the
dev machine (which I set up), the code was working fine (the code takes
that image and inserts it in the middle of a larger one that I'm
drawing). I was wondering why the image wasn't appearing in the picture
I was generating on the production machine (which I didn't set up--that
contractor was around before I got on board and is no longer with us),
and then realized I simply hadn't copied the image over to the
appropriate directory on that computer. However, when I did copy the
image into the right directory, it still wasn't picking it up, so I
restarted Tomcat using the Win 2000 Server Services explorer. However,
the small 1 KB image still wasn't being picked up and placed into the
image I was drawing even though the code was the same as on the dev
machine. I was baffled, and I stopped and started Tomcat a few times and
then it finally started getting picked up! So then I deleted the image
from the directory, restarted Tomcat, and the image was still being found
even though it wasn't there! I restarted Tomcat again, and finally it
wasn't being found anymore. In my code, I'm explicitly specifying that
the image should be searched for in a pretty-hardcoded sort of manner
every single time it's needed, but I'm thinking Tomcat might cache
certain low-level operations in memory (or does Windows do it, perhaps?).
I'm wondering if Tomcat might have remembered that that image hadn't
been found before, so was returning some sort of empty file (though I
don't think there were any exceptions, b/c I've searched for the expected
println statements in my Tomcat stdout and stderr log files) every time
after that...and if it was just in memory, then maybe stopping Tomcat
from the Windows Services explorer doesn't get rid of Tomcat's stack
memory (maybe Windows maintains that memory until you restart Tomcat,
even it seems like that wouldn't be the behavior you'd expect).
I've included the code down at the bottom--it's pretty straightforward.
I'd really like to know, because there have been times when I have tried
to deploy updated JAR files and Tomcat just wouldn't pick them up. When
a modified JSP isn't being re-compiled, I know to go search for the
genereated Java code and class files in the work directory and delete
them to force re-compilation, but I don't know what to do it to find a
newly modified JAR file! Or in my other case, a newly modified image!
Thanks for any clarifications!
Here's the code I was referring to:
String logoLocation = GlobalSettings.getSetting(imagedir) +
AE89x35.png;
try {
//Image logo =
Toolkit.getDefaultToolkit().getImage(logoLocation);
javax.swing.ImageIcon logoIcon = new
javax.swing.ImageIcon(logoLocation);
Image logo = logoIcon.getImage();
//System.out.println(logoLocation is + logoLocation);
if (logo == null) System.err.println(logo is null, and toString
gives + logo.toString());
// Draw image
boolean drawn = oCanvas.drawImage(logo, 185, 190, null);
//System.out.println(drawn is + drawn);
} catch (Exception e) {
System.err.println(Unable to find Airborne logo at +
logoLocation + : + e);
}

RE: Tomcat exception report I don't understand
I'm not entirely sure my JDK is the exact same, so I guess that could be the problem. Anyway, those two extra JAR files in my Tomcat common lib have been copied to the production server's Tomcat's common lib, and now the site works without any such exception. So is that the most likely cause--that I'm using a different JDK than the other developer? I've got 1.4.2--is there some reason I would need xercesImpl.jar and xmlParserAPIs.jar?

Tomcat exception report I don't understand
We have a web app on a server that a contractor developed remotely using JBuilder 7 Enterprise, and I'm a new guy in the office who's trying to modify some of our site code on a dev laptop using JBuilder 9 Personal and Tomcat 4, version 1.1 (the same as what's on the server). I took great pains to make sure my localhost configuration matched and that as much as possible, locations and such wouldn't be hardcoded (and therefore machine-dependent). Last night was the first time I've tried to roll new code changes by simply dropping a JBuilder-built JAR file into Tomcat's common\lib and then dropping my updated JSP pages into their respective places. There are actually two semi-related webapps (in two different directories in Tomcat's webapps\ directory) that both use common code in my site's JAR file. When I tried logging into the first app, it failed, and I'll include part of the page I got down below. To get into the second app, you have to login just as you do for the first app, but if you're already logged into the first app, you can simply browse to the second one (e.g. highlight that part of the URL and replace it with the appropriate directory name). And when I did that, the second app worked fine! So, I know that at least a large part of my JAR code works, at least with the second app (and hence there should be no problem there). Also, I didn't change the login page, so it can't be that (but I know it's probably JAR file code that that page eventually accesses, since it calls some bean methods to set things up). I did find one notable difference between the Tomcat directories on the two machines. On my machine, I have two extra JAR files in Tomcat's common\lib directory: xercesImpl.jar and xmlParserAPIs.jar I've tried Googling a bit, but I'm still not really sure what these do or where they came from (did I get them when I downloaded Tomcat?...if so, why aren't they on the other machine if it's the same version of Tomcat?), but at least one of them seems related to my problem since xerces is mentioned when Tomcat throws up. I did check the two xerces.jar files, and they have the same modification timestamps (Oct 8, 2002), so I assume they're probably the same version! Here is what appears directly under root cause on the Exception Report: javax.servlet.ServletException: org/apache/xerces/parsers/AbstractSAXParser at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:536) at org.apache.jsp.Login_jsp._jspService(Login_jsp.java:150) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:137) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) To reiterate...I could apparently log into my site since I was already logged in when I tried to access the second app, but then something else beyond that didn't work on the first app. I would appreciate any suggestions as to what the problem could be. I'm wondering if those extra JAR files might be picked up by the compiler and so confuse things. I would test that right now, but I can't retry my dev site on the production server until late tonight. We really needed to get these new changes rolled last night, so that's why I'm doing what I can today to figure out what the problem could be before I try to roll again with only blind guesswork.
