tc 7.0.47 manager-gui role works on 32 but not 64 Ubuntu 12.04 (401)
Howdy, Extensive Googling for manager-gui role not working for the same environment finds no solutions. Is this a known issue? out-of-the box install of TC 7.047 on 64 bit 12.04 Ubuntu returns a 401. The same version installed on 32 bit Ubuntu 12.04 manage-gui role brings up the manager page OK. The server is running @ http://localhost:8080 but not http://localhost:8080/manager/html with the standard page returning howto edit tomcat-users.xml However, following the instructions to the letter plus variations gleaned from the net fail. I have been installing TC as a development server for some years and I have never had the tomcat-users.xml config fail. Any ideas, suggestions welcomed. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
tc 7 out-of-box won't run localhost issue on 8005 a vulnerability?
Hello, I have found a situation that kills tc on startup within about 3 seconds on a 64-bit cloud running Ubuntu server. localhost resolves correctly via dig but if we ping localhost it resolves to localhost.com. this in my estimation is causing tc to bail. the tc 7 installed is 64 with a sun-oracle 64 bit jdk all fresh out-of-the-box with no config or changes. This is a vulnerability in my estimation unless somebody can prove different. catalina.out only shows the 8005 port exception unable to bind to 8005 on localhost. i have already run all the possible tests for previous version of tc running or some other process or daemon attached to 8005. There are no other instances on the system and tc could not have previously been running since this was a new out-of-the-box install with no changes. The, on startup the tc 7 instance dies immediately (about 3 sec.) with only the same 8005 exception in the logs. Is it possible to define some other ip than 127.0.0.1 to use for 8005? Pls advise. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: tc 7 out-of-box won't run localhost issue on 8005 a vulnerability?
OK, here is the hogwash. I have already been round-and-round with the cloud admin guys with all of their requests for: netstat, lsof, ifconfig on-and-on. Anyway you slice it some random network config whether correct or not should not be shutting down a server upon boot. Especially, where there is no logging to speak of to shed light. And, this not an AIX but an Ubuntu 10.x Lucid server with all the major services running including NAMEd, SMTPd, HTTPd, SSHd, IMAPd, MySQLd and others with not a single hitch-in-the-git-along except for TC. JDK (sun-oracle 6.26 64) and TC 7 (64) are both fresh out-of-the-box install with no futzing about with any config.

Hello Ranier,thanks for this. something installed changed the hosts value in nsswitch.conf. TC cranked rite up. should be some better way of avoiding this type very infrequent hole to step in. Anyway, thanks again. :-D On Tue, 2011-07-12 at 22:59 +0200, Rainer Jung wrote: On 12.07.2011 22:08, David Brown wrote: david@dobbeltganger:~$ ping -c 3 localhost PING localhost.com (64.99.64.32) 56(84) bytes of data. 64 bytes from 64.99.64.32: icmp_seq=1 ttl=246 time=16.9 ms 64 bytes from 64.99.64.32: icmp_seq=2 ttl=246 time=17.0 ms 64 bytes from 64.99.64.32: icmp_seq=3 ttl=246 time=16.9 ms OK, so that's a problem, localhost resolves to some remote host. david@dobbeltganger:~$ cat /etc/nsswitch.conf ... hosts: mdns4_minimal [NOTFOUND=return] dns mdns4 files Aha, so /etc/hosts and DNS are not really used on that system, instead it will first ask multicast DNS, which is patr of ZeroConf.

New TC 7 tomcat-users.xml can't login (401)
Hi, I have a new TC 7 running. I have RTFM on the new changes for the User realm using the new roles: manager-gui and admin-gui but all I get is 401. server.xml seems to default to usage of the tomcat-users.xml. Any ideas of how to diagnose are welcomed. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I tested using Apache2 and the problem does not show up there. Using apache

The first snippet is from between the web server and tomcat through the JK
connector. This looks the same for either Apache or SunOne.
The thing to note is line 00c0 where the hex is 1f f8.
The second snippet is when a browser hits Apache. The thing to note is line
0130 where the hex is 0d 0a 0d 0a. (carriage return, line feed, carriage
return, line feed)

Is there any way to get the JK Connector to work the same for SunOne as it

Problem with JK connector on OpenSolaris and SunOne webserver 7

Are there issues with running multiple instances of tomcat?
We are currently running two instances of tomcat on our systems. One is for a vendor specific application and the other is for in-house written applications. We are careful to make sure the ports do not conflict and there are plenty of resources to support both; memory and CPU. Recently the statement has been made that the two instances can conflict with each other and cause issues and instability with the applications. Is this true? I was under the impression that since they are in their own JVM's neither tomcat would have any affect on the other. If there are issues in what form may they take place?
Re: Tomcat Cisco Loadbalancers
Hello Steve, this does not mean there is anything inherent in the use of the loadbalancer that is causing the problem. IMHO you need to establish a baseline metric with a real JVM testing tool (like JMeter). You need to create a model of the real production environment and network topology using some type of separate dev environment. Start with just one instance of Tomcat using a true distributed master/slave type test (Hardware and software). Increase the number of users (ThreadGroups) until you can get a repeatable exception as you have posted. Minimally, you should be able to force the application to drop transactions at a certain and given number of users. Once you have a baseline metric to work with then you can increase the number of deployed TC instances and repeat your test. Also, check for you Tomcat installation: client or server? What is your JVM Eden tuning? Many other possibilities at: http://wiki.apache.org/jakarta-jmeter/ (Peter Lin etc.). Or scale vertically instead of horizontal (ibid Peter Lin). HTH.

Re: Tomcat Cisco Loadbalancers
Hello Steve, excuse the top post but one caveat: IMHO as I hurriedly explained in the first post the all-around best and SERIOUS tesing using JMeter is the distributed testing. However, like a lot of FOSS JMeter is not without a gothca: JMeter has a concurrency problem but the work around is easy. One rule: one user per ThreadGroup. If you need more users then just create more ThreadGroups. I was able to conduct some very serious testing for a multiple Tomcat installation assessment at Chevron. The beauty with JMeter is, as you have seen, out-of-the-box JMeter and a decent JRE is all that is needed. My point here is: if you do conduct a distributed test all that you will need is one master machine (JMeter Test Plan box) and as many distributed slaves as you can muster. Since you are an admin guy you should be able attain hardware: anything will do for the distributed slave (laptops, old towers, any OS: Linux, XP whatever). Chevron projected there web apps to expand to 25k us ers internally and so I was able to construct a dev/test model of their topology and I was able to get the application to fail at about 25 concurrent users with a 1 second ramp time. This will give you a baseline metric to use as a reference when you begin making performance and tuning changes to see if you get a better server. Also, if push comes to shove the JMeter has a very nice JUnit sampler that if you get the TC source you can compile the source with a JUnit TestCase in the appropriate spot in the code. This will give the best and most revealing source of problems assuming your assertions are correct. HTH, David. Steve Burt wrote ..

Re: Fwd: jsp:useBean is giving error
Hello Sneha, you can put files directly into Tomcat deployment but it needs to comform to the .war (web archive) file structure. How are you building your application? I suggest strongly that you use Ant and build.xml to output a proper .war representation of you app. Since you are using JSP I assume you are using Servlets and attempting to deploy a web application based on those technologies. You may want to get started at: http://jcp.org/aboutJava/communityprocess/mrel/jsr154/index2.html and also if you have a TC istance running then you should see the documentatio link at http://localhost:8080 assuming you are just running a local TC instance. If you are running public I suggest that you run locally for a while until you have a more stable working environment. Try building a .war first and then use the TC manager to deploy the .war: http://localhost:8080/manager. It works. HTH. Sneha Manohar wrote ..

Re: Tomcat Cluster
Maybe Dave means to just run one Tomcat instance. There is in the TC doco info about the minimalist TC if memory serves. Since you are attempting a type of load-balancing it would serve you well to reply with a lot more info about your overall architecture: OS: vendor, build version, updates (service packs). HW: (manufacturer, # of cores, # of chips, clock, memory, bus, etc.). See: http://www.spec.org/cpu2006/results/rint2006.html Network topology (lan, wan, routable, non-routable, dns, proxy, web server, firewall, etc.). ASCII network map is good for the ML. TC: version and configuration. LOGS: logging configured and enabled. If you can download and compile TC locally then you can run Log4j from within the code in an effort to see where you problems reside with running two instances. N.B.: my current gig requires that I run multiple TC instances. I will reply with my success or failure for review. Andrew Hole wrote .. What you consider the minimal configuration?

Re: Fwd: can't get servlets to run
Hello ilene, in fear of retribution I must give you the standard: http://jcp.org/aboutJava/communityprocess/mrel/jsr154/index2.html Moreover, you might want to learn and understand the web application deployment file system hierarchy as it exists under the Tomcat installation. The TC file system is fairly much the same regardless of platform. This being said I would like to point out that in the future to get expert guru Tomcat help you might want to clarify your issues in a bulleted or tabulated form. This should included log file snippets from say: server.log. Java Exceptions are very informative combined with other pieces of information.

Re: how to auto redirect to https from http
Hello Dave, this is not exactly the answer you are looking for but I have been concerned with public web security for a long time and I have finally resigned myself to the fact that if you are using login pages that process user ids and passwords and other confidential info that man-in-the-middle and any type of network traffic sniffing is extremely dangerous. I run several Java apps publicly and all are 100% https/SSL all the time. It is a performance hit but I just up the hardware to match: multi-core Linux boxes with smp and 4+ gigs mem and other virtualization tricks as afforded by XEN and even Tomcat itself (6.0). Also please note: JBoss is very good at multi-instance web application servers on multiple ports with only a single machine install.

My questions are:1) For failover, if I am using apache/mod_jk as a load balancer, will it automatically detect if one of the members in the cluster is down and not route requests to it? Yes, if the problem is formally detectable, e.g. network problems, no responses etc. What problems get detected depends much on configuration. Have a look at http://tomcat.apache.org/connectors-doc/generic_howto/timeouts.html and for a complete list of attributes at http://tomcat.apache.org/connectors-doc/reference/workers.html You should configure a status worker, such that you can inspect your load balancer status via a HTML GUI. See http://tomcat.apache.org/connectors-doc/reference/status.html 2) Are there any issues assoicated with SSL and apache as the load balancer? Not that I'm aware of, but maybe I don't get the point. Usually you terminate SSL on httpd and then simply use AJP13 as a protocol between mod_jk and Tomcat. More or less it's the only protocol mod_jk speaks. The module then automatically tells Tomcat, if the original request was coming in via http or https. 3) Are there performance gains by using Apache/mod_jk as the load balancer, or should I just use another Tomcat instance and the balancer web app? More often performance is not the key decision criterion. I assume the balancer webapp is not really production grade, but others might correct me here. To choose the right load balancing solution, you have to decide which people should administer and troubleshoot it, and which technology best fits their skills (network appliances, Apache web server with mod_jk, ...).

Re: How to use https together with http
Hello Dave, in the future reply with more info and you will get better help. I will put an example at the bottom. I'm an old-school JSP guy and not a JSF guy but I understand that JSF files still end in (dot).jsp? If I'm right then the rules should apply where a security constraint is defined. You will have to use a realm. The Tomcat default install comes with an example that does this in server.xml. Use a JAAS realm or a LDAP realm for FORM based security. security-constraint/security-constraint The path to your confidential pages need to be defined here. The warning comes (especially I.E.) because you do not have a CA CERT for ssl. You can generate your own CERT with the gentool. Again, the Tomat doco is your starting point: http://tomcat.apache.org/tomcat-5.5-doc/ssl-howto.html and http://tomcat.apache.org/tomcat-5.5-doc/realm-howto.html#What%20is%20a%20Realm?

Re: Tomcat Performance
Hello Peter, Wow! this is good stuff: exactly what I needed. I feel sorry for the client when they see that first baseline! Thank you! David. Peter Lin wrote .. from past experience, it's much better to use hardware load balancing. At a previous job, we had any where from 12-24 servers load balanced behind a cisco local director. Any load balancing router today can do the job, it doesn't have to be cisco. What I did in the past was to take production logs and run them in jmeter against a cluster of tomcat servers. All the servers were behind the load balancer. After the test was run, we collected the logs to make sure the load was distributed evenly and we generated reports. From those reports, we compared the results of the new system against the system we were replacing. That established the baseline performance for untuned tomcat. I then spent a week going through 10 different jvm settings and running a full set of benchmarks on each. At the end I looked at what concurrent loads the entire system needed to support and chose the settings that match those needs. In my test suite, I varied the number of concurrent connections, think time between requests, ramp up time and a mix of requests. the key to tuning the system correctly is understanding exactly what kind of traffic you expect. of course that isn't always possible, so you might have to take a guess. peter On 1/30/08, David Brown [EMAIL PROTECTED] wrote: Hello Andrew, reading your email, Alan's email and the Mladen email piqued my interest because I am currently working on a gig to improve the performance and monitoring of two Tomcat instances supporting 3 web applications and one web service.

This introduces a new variable called Average Application Response Size (hereafter AARS), that is the number of bytes of all context on a web page presented to the user. On a standard 100Mbps network card with 8 Bits per Byte, the maximum theoretical throughput is 12.5 MBytes. 12500 Concurrent requests = --- AARS (KBytes) For a 20KB AARS this will give a theoretical maximum of 625 concurrent requests. You can add more cards or use faster 1Gbps hardware if need to handle more load. The formulas above will give you rudimentary estimation of the number of Tomcat boxes and CPU's that you will need to handle the desired number of concurrent client requests. If you have to deploy the configuration without having actual hardware, the closest you can get is to measure the AART on a test platform and then compare the hardware vendor Specmarks. I would like to launch a discussion on the validity of this formula and, in case of inappropriate, to try to get a more accurate formula.

You need to evaluate you overall architecture from a high level perspective. With this said the questions then are: * What is your planned network topology once you go to production? This question naturally leads to what is your hosting options? If you have a datacenter and have configured and installed your own servers is the best. Next option is to build your servers and then co-locate. The least advantageous option is renting servers (serverbeach.com etc.). If you are hosting locally what is your upstream provider? (fat pipe) and type of connection: T1, T3, OC1, OC3 etc. * Type of scaling (horizontal vs vertical) * Invariably performance issues are rarely a result of the web container (Tomcat). You need to look at the developed software (dot).war that is deployed on TC (use JMeter or some recognized software testing tools). * I have worked on high volume financial web applications that are running at 3 to 4000 transactions/sec. A transaction is end-to-end a round-trip time starting with the HTTP connection, processing and connection to the backend DB, query results returned and subsequently a results web page displayed. This is a HTTP get, put or post transaction. * You are hitting your TC with 3 transactions with a ramp up speed of 10 seconds so you are at 3000/sec. If as you say the web container is not handling this you still need to look at what you web application is doing. Ultimately, using JMeter you need to look here: http://wiki.apache.org/jakarta-jmeter/ A expert in this area is Peter Lin: http://tomcat.apache.org/articles/performance.pdf The JMeter has specific JSF testing reading: http://wiki.apache.org/myfaces/PerformanceTestingWithJMeter Ali Ok wrote .. Thanks David, I mean, if I make 3 requests in a very short time (about 10 seconds); Tomcat does not respond. I read books, tutorials, faqs and threads at maling list about Tomcat tuning. But I couldnt find an example server.xml file used in production or real test results. So I cant understand if 3 requests in 10 seconds is normal or not. 2008/1/26, David Brown [EMAIL PROTECTED]: Hello Ali, please find included below a link URL that addresses the JSF performance issue. A much more rigorous test would be to use the JMeter distributed testing using the JMeter server. HTH, David. Ali Ok wrote .. Hi, We are building a web application with JSF. Last day I tested it with JMeter. Results are bad (I guess). Then I tried to send 3 requests with JMeter to Shuffle Example in Tomcat's examples directory with a limited size of (256 MB I think) memory resource given to Tomcat. This Shuffle Example does not query database or does not make complicated operations as you know; it is very simple. Question is, what should I expect? Does it have to respond all requests? Or is it normal to throw an exception about Too many open files (I use NIO connector) and finally OutOfMemoryError and parachute-thing? After I solve this, I can go on to JSF application testing. I couldnt find documents enough about this issue. Can you send me some links?

Re: Tomcat installation/deployment question
Hello Sushil, IMHO: ANT 1.7 has much improved deployment features in the area of remote distributed deployments. Sureka, Sushil wrote .. Hi, We are intending to deploy our application on individual laptops (to be used by field personnel who does not have internet connectivity to connect to our central server). The idea is that a trimmed down version of our core application will be deployed on individual laptops running tomcat against a light weight Sybase database. I wanted to see if you had any suggestions about - 1. How best to deploy the initial version (5.5) of Tomcat on individual machines - We understand our options are Microsoft SMS, Java Web Start application, shell script or Ant script to install Tomcat on these laptop boxes. We are leaning towards Microsoft SMS since (a) It can easily mass deploy the app to hundreds of machine (b) It is currently used in our organization to deploy some asp application. If you believe there are downsides to this approach or other approaches are better please let me know 2. How best to deploy the upgraded version (6.x or higher) - We potentially could use the same approach as the first one, but wanted to see if the opinion differs. 3. And finally the rollout of initial app and upgraded app version. Again probably use the same approach as before but wanted to throw this out there in case there are better ideas. Please let me know your thoughts on this. Sushil - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: how to install tomcat on iseries AS400
Hello Vida, back in 1998 I had to install Java classes on an AS400. The IBM boxes do not have hierarchical file systems such as: UNIX/Linux/Windows.IBM uses some type of formatted file system using HEADS, CYLINDERS and TRACKS. In '98 IBM provided something called the Q shell and a green screen terminal window from whence to issue commands: define classpath, java and javac path etc. That was then. In all-likelihood you will need to get an IBM green screen session going if the iSeries interface does not have something already available for such purposes. My money is on digging into the iSeries features. HTH, David. Vida Luz Arista wrote ..

Re: Tomcat 5.5 won't start up anymore after adding/removing webapps
Usually in the past web based deployment/undeployment has been through the manager app and not the admin app. The work directory is only for the compilation of the JSP. Can you deploy using ANT? Please reply with more info and maybe you will get a better response: OS: type/version JDK: version Install dir: (path) c:\Apache Tomcat\whatever or /usr/local/Apache... JAVA_HOME: path CATALINA_HOME: path CLASSPATH: path ANT_HOME: path Karr, David wrote .. I installed v5.5.25. I installed the admin app (although the instructions on doing this seem uncertain). I used it for a few hours, deploying and undeploying some experimental apps using MyFaces and RichFaces. Now, for some reason, I'm finding that Tomcat won't start up at all, and I've undeployed all the apps (except the admin app) that I had deployed. I first only removed the war and exploded dir from the webapps dir, but then I tried removing them from the work/Catalina/localhost directory also. The error I'm seeing in the localhost log is this: java.lang.ClassNotFoundException: org.apache.myfaces.webapp.StartupServletContextListener at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader .java:1362) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader .java:1208) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.j ava:3712) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4216 ) Obviously, since something is still trying to reference MyFaces, there's some remnant of one of my deployed apps lying around in a place that I'm not aware of. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: help with tomcat thread pool
Try jakarta.apache/jmeter Robson Hermes wrote .. Hi I'm using Tomcat 5.5.17 with jdk 1.5.0_14, and i want to know what is the best way to check if the tomcat thread pool is working all right.

So, I think that the tomcat thread pool aren't working all right. I try lambda probe, but it's doesn't show how many threads are blocked (it just list, does not count, there are a lot blocked sometimes), and for how long they are blocked. I am trying jconsole, but the server its on a remote site, when I click on the Thread tab, it freezes. If there is another way, please tell me.

Tomcat 4.x, 5.x Client mode vs Server mode and JAVA_OPTS, how-to-know which is running?
Hello TC committers, contributors and users. I am a long time TC user and it is the reason I have my current gig. In spite of the length of time using Tomcat I was not aware of the Client vs Server mode using the JAVA_OPTS variable in catalina or the startup script. Currently, I am using JMeter to assess the webapps running under TC. I suspect a lot of my clients problems reside with the deployed webapps and not-so-such problems with TC. This being said I would like to investigate performance issues with TC i.e. the so-called Client vs Server mode. Is there some definitive test to know which mode a currently running TC instance is running under? There are 3 instances I have to deal with: development deployment, test deployment and production deployment. Obviously, I cannot do anything to the Production app server that would risk bouncing or shutting down the box. JMeter monitoring does not work under TC 4.x because there is no manager/status page from which to parse the XML data. The currently running TC instances are deployed as Services under Windoe 2003 servers. I examied the properties dialog boxes from the Services application and I do not see any reference to JAVA_OPTS or any type of startup params. If anyone has TC Client vs Server mode expertise or if you just want to rant and rave please reply. The particulars follow. Thanks, David. OS: Windows 2003 server SP1 TC: 4.x and 5.x JDK: 1.3.x and 1.4.x Deployed as a service in all instances. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Vista client problem
I've been having the most peculiar issue on a website, (Ubuntu server, running apache 2.2 / libapache2-mod-jk / tomcat 5.5). I initially thought the issue was to do with my servlet not sending proper response headers but it turns out its specific to Mod-JK, the problem only occurs on a Vista workstation. I have a specific JSP page which returns encrypted text data representing a certain configuration item for a user. When the I call the url which returns this page on Vista, from either I.E. Firefox or even Telnet! - The download starts then progressively slows down until it stops.. The downloads only around 40k but never finishes. If I try the same call to the URL from XP or Linux, firefox or I.E, it works fine. When I bypass Apache Mod-JK and call the url directly from tomcat, i.e. on port 8080, it works fine. IF I call the URL via HTTPS, it works fine. The problem only occurs when the request is being process through Mod-JK. Does anyone have any idea what could be causing the problem ? I'm using a very straightforward Mod-JK setup. my jk.conf is as follows.. IfModule !mod_jk.c LoadModule jk_module mod_jk.so /IfModule JkWorkersFile /etc/apache2/workers.properties JkLogFile /var/log/apache2/mod_jk.log JkShmFile /var/log/apache2/jk-runtime-status JkLogLevel warn and in workers.properties; workers.tomcat_home=/usr/local/tomcat workers.java_home=java-1.5.0-sun-1.5.0.08 ps=/ worker.list=shibboleth # Definition for local worker using AJP 1.3 # worker.shibboleth.type=ajp13 worker.shibboleth.host=localhost worker.shibboleth.port=8009 If anyone has any thoughts/hints of where I could look it wouldbe greatly appreciated..

Re: Vista client problem
Binary content / All other parts of the site work fine. This jsp contains nothing but garbled text , E.G. a$HHajshdashjk^SDAH*HAD But thats fine, thats intended. The problem is the transfer.

Can Mod-JK interfere with the headers ? If it was a header issue, I think the problem would be there constantly, not just when the request has to go through mod-jk.
