Running Tomcat on multiple processors on Windows 2003
Hi, All, A client of mine is having trouble getting Tomcat 4.1.27 to make use of multiple processors on his quad processor system under Windows 2003. My questions: 1. What can he do to enable Tomcat to make use of all 4 processors? 2. If a single instance of Tomcat can't make use of multiple processors, is it possible to set up multiple Tomcat services, each tied to a processor [I understand completely how to set up multiple Tomcat services, I just don't know how to tie them to a specific processor]? Here are my client's answers to my questions regarding his configuration: * Which version of Windows are you running? Windows 2003 * Which specific version of Tomcat are you running? Tomcat 4.1.27 with the -server flag set * Which version of the J2SE SDK are you running Tomcat on top of? JRE is 1.3.1 * Are other applications successfully using the multiple processors? Yes, Cognos is spawning processes that recognize the multiple processors * How are you determining that Tomcat is running on only one processor? When I look in Task Manager, I always see one processor running at 100%. When I look at the running processes, the java.exe, is running at 13%. This server has 4 processors, and is using HyperThreading, so Windows sees 8 processors. Does anyone have any suggestions? Thanks so much for your help.

Clustering question
Hi, I have setup two tomcat 5.5.7 servers which are clustered. Everything is working and the basic session is replication. However, when I add my own custom java object to the session this is not replicated. I have made it Serializable but this object also contains other java objects which are not serializable. Is this a problem? Is there anything special I need to consider to get my custom session objects to replicate??

cache issue
Hi, When using tomcat 5.5.7 with apache 1.3.x I have problem that pages I have visited before are cached in the browser -so changes cannot be seen. I don't have this problem when I just use tomcat as the web-server, only once I started using apache. Clearly this is a problem because the url is the same and that's just they way browsers work. Is there any solution to this problem. Is there some way I change add a random parameter to each url request (built with c:url for example http://domain/mypage.jsp?random=tr445e) - that would fix it or is there some config property in apache/tomcat to resolve this?

mod_jk2 and LocationMatch regexps
Hi, I'm trying to adjust the mod_jk2 JkUriSet entries for my server (apache 2.0, mod_jk2, tomcat 4.x). Specifically, I'm trying to set up some static files to be served by apache, not by tomcat. However, it seems the LocationMatch is very greedy and tends to intercept *all* requests that contain the path string. For example, assume I have the static file under apache htdocs: /var/www/htdocs/stuff/foo_bar.html And I have a webapp under tomcat: /opt/tomcat4/webapps/foo/ I have this mod_jk2 entry: LocationMatch /foo JkUriSet worker ajp13:localhost:8009 /LocationMatch This URL is properly forwarded to the tomcat foo webapp: http://www.example.com/foo However, it *also* forwards: http://www.example.com/stuff/foo/bar.html And even: http://www.example.com/stuff/foo_bar.html According to the docs, LocationMatch is supposed to support a regexp for the URL, but I can't seem to figure out how to get it to only forward foo at the beginning of the path. I tried: LocationMatch ^/foo This caused: [error] uriEnv.init() context must start with '/' in ^/foo I also tried: LocationMatch /^foo Which simply didn't forward http://www.example.com/foo to the webapp. I also tried simply changing LocationMatch to Location, in the hopes that Location's simpler specification might naturally Do The Right Thing. But it didn't foward http://www.example.com/foo to the webapp. -- Steven J.

Can servlet mappings be done somewhere other than web.xml?
I'm currently working on a legacy Tomcat 3.3 project that was developed (not by me) a couple of years ago, and I am having a heck of a time understanding how servlets are getting mapped properly. A typical URL in the application is of the form CONTEXT/servlet/servletName - nothing fancy there. However, the webapp's web.xml file contains no servlet-mapping tags, but just the servlet-name and servlet-class tags. Is there another way in Tomcat to map URL's to servlets, either through a server configuration setting or some other global information contained in a conf/xml file that I'm not aware of? My problem isn't that the servlets aren't being accessed - they display content fine. I'm for now just trying to understand how Tomcat is associating the URL string with the actual servlet class since there is no servlet mapping being done in the web.xml file. The servlets themselves reside in jar files under CONTEXT/WEB-INF/lib. Thank you. Steve Beckle Computer Associates tel: +1 (630) 505 6855 fax: +1 (630) 505 6983 [EMAIL PROTECTED]
LD_ASSUME_KERNEL with tanuki wrapper?
Hi, We're running: fedora tomcat 4.1.30 tanukisoftware.com wrapper # rpm -q fedora-release fedora-release-1-3 # uname -a Linux example.com 2.4.20-021stab022.5.777-enterprise #1 SMP Fri Sep 3 12:45:02 MSD 2004 i686 i686 i386 GNU/Linux We're seeing tomcat crash and occasionally hang (and refuse to let go of port 8080 without a kill -9). Everything I've found seems to point to this being a classic LD_ASSUME_KERNEL issue. The gotcha here is that I can't seem to find the right way to set the LD_ASSUME_KERNEL environment variable so that it will get through the service script. It seems that service is using /etc/init.d/tomcat4, which in turn is a link to /opt/tomcat4/bin/tomcat4. I've tried adding LD_ASSUME_KERNEL in there. I've also tried adding it in /opt/tomcat4/bin/setclasspath.sh. I've tried setting up a .bash_profile in /opt/tomcat4 (which is the home directory for the tomcat user). One caveat is that I may not be using the right technique to check on things. I've been assuming that if I do ps -fu tomcat and then cat /proc/pid/environ I should see LD_ASSUME_KERNEL show up in the environment variables for the tomcat process.

configure a jndi resource
Hi, I would like to configure my jms router resource directly in tomcat and perform a jndi lookup to get this resource. But I am not sure how this is working.

Re: Virtual Hosts and SSL
Mike, On Fri, Dec 17, 2004 at 02:04:43PM -0800, Mike Kennedy wrote: I can't find anything specific to my question in the FAQs but I'm trying to set up a tomcat server with virtual hosts using https. I have two ips, each with its own SSL cert as I understand is necessary for https. What I want is to have each ip use port 443 with its own document tree (virtual host) but I cannot seem to get this to work. When I set up an additional ip to use port 443 I get an error 400 (bad request). I'm not sure what you mean by virtual host. AFAIK there are generally two uses of the phrase. The first is to refer to a single web server answering to more than one domain name _without_ using one IP address per domain name. The second is to offer a customer seemingly full access to a server to run their website, without having one separate physical box per customer. Some solutions go all the way and try to make the customer feel like they have root on the box. Some solutions just provide the customer a greater-than-end-user level of access to tweaking the configuration of their webserver, cgi scripts and database. If you're asking the first, I don't know if my recent learning experience with Apache Virtual hosting will be relevant, but it may be give you some insight into what you're doing. It may only go for tomcat used in an apache/modjk/tomcat setup. Or it may not be at all relevant to tomcat, whether stand-alone or with apache. I recently re-installed my apache server, and in the process set up apache virtual hosting. I learned that it's almost impossible to set up SSL with virtual hosts with apache, you need to use IP-based hosting if you want to serve multiple domains from one apache installation via SSL, without any hitches. That said, if all you really care about is encrypting the connection, non-IP based (i.e. virtual) multiple domain hosting is still tolerable. Basically the SSL cert that's served by the server will match the default virtual host (the first one defined in the configuration). Requests to the other domains on the SSL port will hit the same SSL server and get served the SSL cert for the default domain. The browser will squawk because the Cert doesn't match the domain. If you're *really* security-conscious, this is a problem, since there's an opportunity for a man-in-the-middle attack. Somebody could slip the browser a bogus Cert and proxy requests to your server, eavesdropping on them all the while. But if you're just providing some encrypted web-access to an application, you may not mind. Security is all about trade-offs. -- Steven J.

Re: RES: [java] RE: http-https url rewrite bug TC 5.0.28?
On Mon, Nov 15, 2004 at 05:13:21PM -0300, Paulo Alvim wrote: I have a similar problem: I'd like to use https only with the login.jsp page and come back to http after that. Could you explain why it isn't possible? It's not possible because it's not _proper_ from a security perspective, so they built tomcat to not enable it. I can sorta understand why people want to do it, myself, but you should understand that it's not secure, and be very much aware of the risks you're taking. Still, I can understand some of the motivation behind the request, and I think there's a solution. The key is to realize you're trying to solve the wrong problem. See my explanation at the end for what the right problem is, and how to solve it. To illustrate this properly, imagine that your account has two usernames and two passwords that you can use to access it, the permanent username/password and a temporary username/password. When you login, you first have to send the permanent username and first password over the net. At that point, the server then sets your temporary username and second password to some random value, temporarily, and then sends those back to you. The temporary username/password will last until your user session times out, or until you explicitly log out. Your browser then sends a copy of that temporary username and temporary password along with _every_ _single_ _request_ to the server. Just because you make sure the first communication, where you sent the permanent username/password, is secure, doesn't keep somebody from sniffing the temporary username and password and using those to do all sorts of damage to your account during that window of opportunity. To bring this back to reality, the JSESSIONID cookie is the temporary username/password. This explains why it is not secure to use the same session for both HTTP and HTTPS connections. Thinking about it, I can certainly see why people would want some happy medium between the two. SSL consumes resources* and often you're not worried about securing the entire series of user interactions, just a critical subset. For example, you don't need to SSL-protect the user browsing your catalog, but you do need to SSL-protect the payment authorization. (* Last I heard, the SSL server takes up about 40% extra resources, though that info is years old and may be way out of date.) However, the important point is _not_ that you want to share the session data across secure and unsecure apps, but that you want to avoid making the user log in twice. Here's how I'd approach this. You need two distinct sets of security credentials, serious and trivial. The serious credential is necessary for the SSL-protected portion, the trivial credential is necessary for the non-SSL portion. Then, when the user logs in via SSL, it also creates a trivial security credential, and sets that on a _different_ cookie than JSESSIONID. It's been ages since I've worked with cookies, but you can mark a cookie as Secure, meaning it only gets sent back to the secure server, or not. The tomcat SSL-created JSESSIONID is set secure, for example. Here's what one looks like: Set-Cookie: JSESSIONID=202E506FAD4A9ADB5F062DB3A3310E89; Path=/xyzzy; Secure This is further documented at: http://www.ietf.org/rfc/rfc2109.txt However, you can also set a second cookie, _without_ the secure option, from the SSL response. The browser will then include that cookie value in further requests to the non-secure site at the same domain. You would have to customize the non-secure site's security so that it checks for this cookie and automatically logs the user in to the non-secure site without prompting. One thing you'll have to watch out for is the timeout of the SSL session, since it might get left alone for many hours. You have two choices there: 1) either include an SSL-protected icon on every page, which will keep your SSL session from timing out. This can have some slight complications, since most browsers use some visual cue to indicated SSL traffic. 2) or just set the SSL app's session timeout to a fairly long time. -- Steven J.

Re: Buffering and redirection to the errorPage
On Thu, Nov 11, 2004 at 11:28:21AM +1100, Derek Clarkson wrote: This sounds like something I have encountered. The basic question is that how do you redirect to an error page if youa re writing to the output stream rather than going to another JSP, and have an exception ? I thought I posted a reply to this earlier, but I don't see it in my inbox, so maybe I should repost. In a nutshell, this topic makes a lot more sense if you understand what an HTTP request and an HTTP response really look like. My number one recommendation to folks doing web applications is to get a packet sniffer, or a logging proxy, and take a look at what the browser and server are actually sending back and forth. Each HTTP request and response look a lot like an ordinary email: a series of header lines, a blank line, and a message body. The header lines are all name: value. In an HTTP response the body is the HTML of the page, or the binary data of an image. In some cases there is no body at all (a client-side redirect, for example). Any logical operation is handled with a header - setting a cookie, redirecting the browser, etc. Once the blank line separating the header from the body has been sent, you can't go back and send another header line. So you _must_ do any sort of redirect before the server starts to flush output back to the client. If you try to set a header after the server has already sent the blank lnie separating the headers from the body, you'll get a java.lang.IllegalStateException. One way to make this easier to do is to set your buffer larger, so the server will wait longer before flushing output to the browser. Another way is to use an MVC architecture. Have the submit from the browser go to a servlet that does any logical processing you need, but doesn't send any output back to the user. Instead, the controller servlet sets request attributes and user session attributes containing the results of the logic, then redirects the request off to the right view page. The view page looks for the request attributes and user session attributes and generates HTML tags for the display. The controller doesn't muck with display stuff, the view page doesn't muck with the headers. -- Steven J.

Do I write my own ticker into each page I want to monitor and store the incremented value to a database? Or is there a much simpler solution already implimented in some tomcat management software AFAIK there isn't any sort of built-in monitoring. The general answer I've seen in the past is that you should use log analysis tools on the logs, which are in a fairly standard format. This probably makes a ton of sense, considering that adding special monitoring would involve adding overhead to every page request, while log analysis could be done to the logs on a separate machine. An alternative would be to code a servlet filter to log the requested URLs. In some ways a servlet filter is much like a servlet; you request a URL, based on an entry in web.xml the servlet engine hands the request to the appropriate servlet filter instance (or if the servlet filter hasn't be instantiated yet, instantiates it and then hands the request to the instance). The way it's *not* like a servlet is that the servlet filter's doFilter() method gets request, response AND chain. Besides messing with the request and response object all it likes (subject to the standard limitations, like you can't write headers once you've started flushing body content back to the client), the filter can call chain.doFilter(request, response), which forwards the request to the original servlet it was intended for. So in this case, you'd set up a servlet filter, define the URL mappings to filter all the servlets and JSPs you care about monitoring, and have it print a log message to a special log file (or to a special logging channel). http://www.javaworld.com/javaworld/jw-06-2001/jw-0622-filters.html http://www.onjava.com/pub/a/onjava/2003/11/19/filters.html http://www.onjava.com/pub/a/onjava/2004/03/03/filters.html -- Steven J.

Multi-Site Clustering? (hot failover)
Hi, I've heard tomcat supports clustering, but I'm thinking about a similar, but different situation: having a duplicate server at a distant hosting center, set up to take over if the first server or the first hosting center encounter problems. This isn't about load, so much as reliability. I don't *think* there are any special things I need to do at the tomcat level, but I figure it can't hurt to ask if I'm missing something. My basic configuration is apache/tomcat/mysql. I think I just need to keep the tomcat webapps on the same version of my application, and that's about it for apache and tomcat. I especially have to make sure the application code is using the same database schema, so I don't get inconsistent data being written to the database. The main trick isn't gonig to be tomcat but all, but rather making sure the mysql database on the second server is set up to mirror the first database, with frequent updates to minimize the window of lost data. The main worry is going to be if the second machine has to take over, and some new data is created in the first machine after that point (i.e. the data gets out of sync). I'm guessing the short answer is to either count that data as lost (i.e. Doctor, my arm hurts when I do this. Don't do that.), or selectively copy the new data over to the second machine, then drop the first database and copy the second database over to the first server. -- Steven J.

Re: Accessing resource in WEB-INF outside servlet
methods, and in fact at some points in the app where I have some tricky SQL I do just that. For example, I have to join tables and I don't want to do one big select of the main table and then a zillion small selects for individual joined rows. I do the SQL query in a separate method, and then use the mapper to convert each row to a bean. This lets me get the benefit of efficient SQL queries in some crucial spots, but still keep a clean O/R sort of feel. I'm still not *entirely* sure whether I want to take it further and just have the CRUD methods live on a generic database class, and pass in a bean and a mapper: List invoices = GenericDB.selectMany(InvoiceBean, InvoiceMapper); I thought about something like: List invoices = GenericDB.selectMany(InvoiceMapper.getSelectQuery(InvoiceBean)) ; But this is really insufficient, since I have to pass the mapper in anyway, to map the ResultSet back to beans. So GenericDB might as well know about using a Mapper to generate the query as well. Overall, I kind of like this refactoring, because it makes the beans and the DBMappers shallower. The bean just knows about data. The DBMapper just knows how to produce an SQL statement from a bean, and a bean from an SQL statement. The GenericDB just knows about beans and mappers: how to apply a mapper to a bean to get SQL, and how to apply a mapper to a ResultSet to get beans. -- Steven J.

Re: How to fix: Tomcat responce time gets to 10-200 seconds once a day
Roman Zhovtulya [mailto:[EMAIL PROTECTED] asked: Normally the performance is really good, but about once a day it gets really slow (around 1-5 minutes to display the page). It also recovers autocatically to normal response time when you simply wait 5-10 minutes. On Mon, Nov 08, 2004 at 11:16:55PM -, Steve Kirk wrote: My favourite answer to any query about a server being painfully slow: does the slowdown coincide with a slowdown or outage of your DNS service? This can have suprisingly big impact if TC is doing reverse lookups of the IP of every request. At the risk of asking the obvious, are you sure that some other heavy process is not kicking off at that time, either on one of the machines you mention, or some other machine on the network? If it's not external load (as SteveK suggests), nor internal load, it might be resource contention. 1) how many apache processes do you have? I had a problem on a redhat box, apparently the default apache install was 10 processes. Needless to say, as soon as the traffic went up a bit, all 10 processes were busy and subsequent requests had to wait for a free process - and wait, and wait, and wait... Does each page load actually load, or does the browser time out while trying to get a connection? If the page takes 5 minutes but actually does load (and if the delay is not because it's trying to shove a lot of data into the page), then it's probably *not* a lack of apache processes. But it's easy enough to check on, so check on it anyway. 2) If it's not contention for apache processes, it might be some sort of contention inside tomcat - either a thread locking issue somewhere, or getting at the database, or some other resource. 3) It may not be actual load, but more time delays. For example, anything in your system that hits an outsid server (message queue, email) may take a couple of seconds to complete. All of those secodns add up. They may also lead to resource contention. One of my earlier servlet projects, the super high reliability message queue (MQ Series - this was pre-JMS) performed as advertised... but the super high reliability big iron it was connecting to was shut down for a couple hours of scheduled maintenance every sunday morning at 1am (which, of course, I found out about one sunday morning at 2am). The message queue's default timeout was kind of high (25 seconds), so the thread just sat there waiting for the answer, holding open one of the apache processes all the while. Soon enough, all the apache processes were busy waiting for answers from the tomcat threads, which were waiting for answers from their message queue requests... The right way to resolve this sort of problem depends a lot on the circumstances, so look into that and post here with further questions. 4) Just a wild idea, but check on garbage-collection. Maybe put a couple of logging calls in the pages, so you can see the memory usage in the log: Runtime.getRuntime().maxMemory() // maximum memory allocation Runtime.getRuntime().totalMemory() // memory actually allocated by JVM Runtime.getRuntime().freeMemory() // allocated but not in use by objects The gotcha to watch out for is that the system will quite happily allocate memory without doing garbage-collection, until it hits maxMemory(). Then it'll do garbage collection, but it may take a while. You can't really eliminate the delay, but you can move it around and/or spread it out. There are command-line arguments to tweak how garbage collection is done. At the time I learned this lesson, I don't think those command-line arguments were available, so I used a call to System.gc() instead. But I'd strongly suggest looking into them before you go mucking with System.gc(). System.gc() isn't guaranteed to do anything. Whether it does anything or not depends on your platform, but it's supposed to sort of nudge the garbage collector and say now might be a good time to clean up. If you have any sort of consistent spot in your app where a bunch of objects become superfluous (in the one where I learned this lesson, it was an object cache that expired objects every minute), putting in a call to System.gc() might really even out the memory usage. 5) Do some very rough thumbnail profiling; print in System.currentTimeInMillis() to the log at a number of strategic points. Then after a slowdown, look at the log, try to trace a single request through the process and see where the big delay was, then take a microscope to that portion of the application. -- Steven J.

If you are running hundreds of tiny webapps it might be a bit of overkill, and if many of those webapps need to be on (for example) port 80 or 8080 then it simply doesn't work. This said, I agree with Yoav - it makes management a whole lot easier and reduces interactions between webapps. I use it wherever I'm principally running services that don't need to be exposed via our firewall. I'm certainly leaning in this direction. I'm using apache to front-end the apps. Can apache/modjk cope with different ports for different tomcats for different webapps? Thinking about it, I have: - apache -- modjk - tomcat -- jdbc driver DBCP pool - mysql If I'm going to have multiple tomcat processes, the main things I would think to worry about (besides sheer disk and memory consumption) are connections between apache and tomcat, and between tomcat and mysql. Apache and Mysql are already handling the current load, nothing should really change about the database tables or the http requests. For modjk, I have no idea what the concerns might be, except to start with, can modjk even do this, using multiple tomcat servers on different ports? For the jdbc driver and connection pool, the only thing I can think of is resource consumption of the database connections, mainly on the mysql server side of the equation. I should look into how many database connections mysql is configured to provide, and how using multiple tomcat instances might affect that. I'm not sure what the answers are, but two questions I can think of: - The multiple connection pools will definitely mean that there will be more database connections kept in overall machine memory (whatever the lower bound is on the DBCP times the number of tomcat servers) at any one time. How will this affect mysql? - The multiple connection pools mean that the collection of tomcat servers will have a much higher upper bound of open connections (normal upper bound times number of tomcat servers). Is there more of a risk of swamping the mysql server? Should I configure mysql to handle more connections, or should I configure the tomcat DBCP pools to allow fewer connections? These are the kinds of topics that I would love to find covered in a best practices for tomcat hosting guide. Any recommendations? -- Steven J.

You're right, this is futile, because it's trivial to get the source of the page, no matter what you do at the browser level. The browser has to see the source to render it, therefore the server is providing the source, upon request, to anything that knocks at port 80 and asks for it. Getting the source is as simple as telnetting to the webserver on port 80 and faking the commands. Or run a packet sniffer in the network you're browsing from.

I'm a little unclear on what this means - do you mean branches? Or do you mean that you effectively do some sort of script to get the latest stage tag vs get the latest prod tag? That's something I hadn't considered, but it sounds like it might be easier than branches (which I haven't really messed with, but seem to be notoriously tricky). When a push script is executed the server pulls the appropriate version from cvs and then performs an ant task to deploy the app, compiling any changed classes. We find that this works just fine and haven't really had any issues. Okay, so ant task to build war file and push it to the tomcat server. Sounds fairly standard (though still unexplored territory for me). Check that you are using jsp:include ... (include on execute) rather than @ include ... (include on compile) as this *may* be causing the issue. Yup, we're using jsp:include. Just out of curiousity why are you are deploying individual apps if they are so similar? Why don't you just implement a branding infrastructure and run a single app with multiple brandings? Honestly, I've considered it several times. We're really, really close to that point already. All it would take would be to switch the various logo.gif and CSS imports to use a property instead of copying a template file. Then I'd set up the property singleton to use a different property file database depending on which URL mapping the user requested. The real reason I haven't is that it just doesn't buy me anything significant to run them all off the same webapp, while it increases (instead of decreases) the interdependency, and makes testing much more white-knuckle. I keep thinking, well, it wouldn't be that hard..., but there's no real concrete advantage to do this, except to save a little bit of disk and memory.

Configuration Management, JSP Recompiles, War Files
Hi folks, I'm interested in hearing how people are dealing with configuration management issues. We've been running into some problems with JSP recompiles, particularly when the changed JSP is an included JSP. Tomcat seems to sort of get stuck on the old version, even if we restart tomcat it doesn't reload. Manually deleting the foo_jsp.java and foo_jsp.class files from the tomcat/working/etc directory and *then* restarting seems to do the trick. Somebody I talked to suggested that using a WAR file and redeploying would make tomcat more reliably recompile the JSPs. I've been meaning to move to using WAR files sooner or later, but one question has always bugged me - how do you save your deployment-specific configuration info? If I understand correctly, WAR file is just a glorified JAR file, which in turn is just a glorified tar file. So unless you're unjarring it, editing the config file and rejarring it, you can't really muck with the config settings inside it. How/where do people normally keep the configuration variables for the webapp? We have a single tomcat installation with a dozen almost-identical webapps, one webapp for each customer. When we do our jobs right, each app is in fact identical, except for: - two colors in the app-wide CSS stylesheet - the customer's logo image - the CONTEXT tags in server.xml - a few details of the web.xml file (webapp name, database resource name) - a properties file with a couple dozen configuration properties - a separate database in the mysql server We extend and refine the application constantly, so we're changing the code every month or two. So far we've been using cvs to manage this. Each webapp is a cvs checkout ; the specific files mentioned above exist in template form in the checkout (e.g. web_template.xml, styles_template.css) that we copy into the right name for deployment and then edit, so they don't get overwritten by cvs. Using cvs worked pretty well for a while, but it's gotten unwieldly, especially when we run into the JSP recompiling problem, because then we have to restart the entire server to try to get it to recompile the jsp. This reminds me of another question; I'm beginning to wonder if we wouldn't be wiser to use a dozen separate tomcat installations. I know that in theory using the same tomcat installation for multiple webapps is supposed to be standard, but any time we have to tweak the server.xml-level configuration of a single webapp, we have to restart all of them. How do people normally deal with this? Is it at all common to run multiple tomcat servers behind apache for this sort of purpose? -- Steven J.

RE: New User needing urgent help
Originally this app was setup to be located outside of the webapp directory in it's own directory. I had it working for the Tomcat 3.3.2 by setting the context on it with no problems. I wanted to make sure I had the latest Tomcat install to ensure that I wouldn't have to upgrade too soon so I did that but couldn't find where I could get it deployed on an absolute path instead of the relative so I set it up in the webapp to make things simpler but then ran into this problem. The support for this software is pretty meager so I am working through it so I can support it myself. From what I see in the software the mapping servlets and such look like they are all in place. Just the location of the whole thing has been beating me up. Perhaps someone knows a way I can leave it outside the root and save me some extra work? Thanks for the help.

We've been using eapps.com and we've been pretty happy with the service. Essentially we get our own installation of tomcat, with an apache front-end that they manage. -- Steven J.

Best Scheduler/Cron for Tomcat?
Hi all, What's the best scheduler or cron for use with tomcat? I've been googling and Quartz and Jcrontab seem to turn up often. The Quartz website says it's used by some Jakarta projects, and I see some references to Quarts in commons-beanutils documents in google. What we're doing specifically: scheduling out-going phone calls from a VoiceXML system to automatically call users at their preferred time. I suspect we're going to see calls cluster at certain points (e.g. 6:00, 6:30, 7:00) so the method that starts the call will have to be multi-threaded, or queued. If I can get some support for that from the scheduler, so much the better. We're on tomcat 4.x at the moment. I plan to move up to 5, but I have a ton of things to do, and I've seen a few posts here that suggest that moving to 5 might involve non-trivial time and frustration. Our app is pretty vanilla, so I'm not especially worried, but I have twenty-seven priority-1 tasks on my plate, so...

tomcat5 server stalling
Hi, I'm running tomcat5 on a Redhat9 box. It looks like its accepting connections for a while, which is good. But then it hits a limit and there are alot of TIME_WAIT connections in the netstat output. Below are the server.xml portions where we configure tomcat to listen and accept connections on port 80.

RE: error starting tomcat5
Thanks that seems to work out. Now I have one last error that I can't seem
to figure out: Where should the commons-digester.jar reside? currently it
is in the /usr/share/java directory (with all the other jars), but tomcat
can't seem to find it. I have it in the classpath as well as the
${CATALINA_HOME}/server/lib directory, is this the right place?

this
error message.

tomcat to start at this point. Any suggestions on how to debug this or if
anyone knows what's wrong that would be great. Please let me know if you

Actually, it is supposed to be part of commons-modeler.jar which should be
living in $CATALINA_HOME/server/lib.

Is there a simple change I can make, maybe switching my System.out.println() invocations to invoke some logger class? -- Steven J.

Alternatives to J2EE Authentication
Hi folks, The most common (and frustrating) bookmarked login page gotcha with J2EE authentication has been oft-discussed (broken as designed) on this list. What are people's favorite alternatives to J2EE authentication? And why? Something I'm particularly interested is alternatives that don't require me to rebuild the application from scratch. I'm looking at tearing out the old login process and putting in a new one and I don't really want to start the whole thing over. If I had to build it from scratch myself, I'd do it as a simple Servlet filter that checks for a Principal object stored in the user's HttpSession. -- Steven J.

Bean Generation Tool?
Hi all, I have this tool I cobbled together for building vanilla java web applications. You feed it an XML config file that defines tables and columns. It generates: 1) source for simple databeans to hold those rows 2) source for simple database access classes (mapping a result set to a databean, composing an INSERT, UPDATE, or SELECT clause) 3) basic JSP forms to edit the beans. I find this tool somewhat useful, I'd like to continue to refactor it and make it more generally useful. I've done some looking at various tools out there. I'm not going to worry about the JSP side much, for the foreseeable future. JSP code is simple enough by itself, and the JSP side always ends up getting massaged extensively, so I'm not sure I really like generating it like this. (I keep meaning to read up on JSF and get a solid idea of what it brings into this but I can't seem to find a simple, concise definition of what JSF is/does.) Hiberate looks very, very cool and I want to move as much as possible to using it for the database side. I don't see anything in Hibernate - or anywhere else for that matter, though I may not be using the right google search terms - for generating the simple databeans. My immediate plans, however, are to: 1) move from using print() to using a more sophisticated code generation tool (velocity?) 2) refactor a lot of the boilerplate that gets wrapped around each databean instance variable into a set of standard input classes. E.g. instead of using a Date class and having a lot of boilerplate generated for each bean for parsing the date on input and formatting it on output, I'd have a DateInput class that would have that, and use a DateInput for the bean's instance variable. This second, in particular, it seems like there should be an existing package for already, but I haven't managed to find it. I'm thinking each input class will have: 1) getters/setters for String inputs from forms 2) getters for producing Strings appropriate to use in an SQL query. 3) an isDirty flag for determining what values where changed from the original values loaded. 4) a collection of InputTest classes that can be run against the value to make sure it's safe to enter. each TestInput would have a isValid() and getErrorMessage() Ultimately/eventually I can see that the forms and the beans and the tables should be more separated. Ideally I'd generate databeans that the forms populate, and have a separate bean-to-database-mapping mechanism. But for now I'm just trying to build a tool to build a simple solution to a specific problem. -- Steven J.

RE: Tomcat, Jonas and Valves.
I figured out the problem. I had installed the valve, in my org.apache.catalina.valves, in catalina.jar in tomcat. I expected that jonas would also run the tomcat scripts, when starting up tomcat. But, instead, jonas runs its version of server.xml and web.xml (in preference to the ones defined in %tomcat_home%\conf) during startup. So, it was when i updated server.xml, in jonas\conf, it was looking for the file in its directory structure, i.e. org.apache.catalina.valves, in jonas, defined in web_catalina.jar. Once I updated this jar to include my file, its working fine with Jonas and Tomcat. The valve I made is a modified version of the RequestDumperValve. Steve.

Classes not recompiling - Have to restart Tomcat

Modifying Requests; Interceptors ?
Thanks a lot Adam. I hadn't noticed that in the server.xml. It kind of satisfies my current needs. I would also require to modify the requests or create responses based on the requests before they are processed by the webapp. How should I go about this ? Interceptors ? If so, can someone please direct me to how I can procure their API, since I do not seem to have that on my tomcat 4.x Thank you in advance --Steven. --- Adam Hardy [EMAIL PROTECTED] wrote: Hi Steven, check out the AccessLogValve in your server.xml Adam On 09/29/2003 11:35 AM Steven Perry wrote: Hello All, I have got Tomcat 4.1.

Re: Modifying Requests; Interceptors ?
I notice that the BaseInterceptor is there in tomcat 3.3.1. How come it is not included in 4.1.27 and 5.0.12 ?

channel.apr values
Hi, I'm a bit confused. I want to set the timeout value to 1. I was looking through the documentation and it seems like channel.apr keepalive set to 1 is what I want. And it looks like it should be in the workers2.properties file and the format should be channel.apr:keepalive=1 is the format. Is this correct, the documentation is kind of confusing on these points.
