RE: How to make tomcat work on a remote server?
This might be something to look at, but I know in Fedora Core 3, the last SE Linux Policy broke mod_jk. You had to either turn of SELinux or modify targeted policy. If you think you may have this problem, look at /var/log/messages to see if the security policy is logging any errors. You can also run: audit2allow -d to see if any policy changes needed to be added.

Just another side note to this thread. I was applying the SELinux Security Policy patch to my fedora core 3 box today and it broke my apache + mod_jk + tomcat installation. The fedora team must of changed the Security Enhanced Linux Policy preventing mod_jk connecting to an external tomcat server. Policy.18 is the culprit I am sure of it. I will research this some more.

RE: mod_jk works as localhost only
Ok, well, I am posting this information to this list in this thread because we kind of got started down the path of SELinux. Fedora Core3 comes with a feature called Security Enhanced Linux. This is a security feature that you may or may not want to have on your server. I chose to enable it, so that is why I am posting this information. The main reason for using SELinux is to have finer grain control over what your processes are doing and how they are doing them. Also this information is output to the logs and is great for auditing. I highly recommend taking the time to read about SELinux if your distro supports it. First of all, I have Apache + Mod_jk on one machine and then tomcat on a separate machine. When I upgraded to SELinux Policy 18, I noticed that apache would not communicate with tomcat using the ajp13 connector. So what do you do? Well you can: 1. Disable SELinux for apache by going into the gui security level settings tool. You have to have a gui installed for this to work. 2. Disable SELinux entirely. Google for this, I can not remember how to do it. 3. Configure your SELinux policy to allow Apache+Mod_JK to work. You can do this my using the audit2allow tool. You also need the selinux-policy-targeted-sources package. Just do a: yum install selinux-policy-targeted-sources audit2allow -d allow httpd_t httpd_log_t:file write; allow httpd_t self:tcp_socket connect; allow mysqld_t ld_so_cache_t:file execute; allow unconfined_t httpd_t:file relabelto; The content above needs to be placed in /etc/selinux/targeted/src/domains/program/apache.te I had to comment out the last two lines because I was not interested in enabling them. The manual on SELinux clearly indicates to analyze the output of audit2allow carefully. Next, cd into the /etc/selinux/targeted/src directory and do: make policy make install make reload Then restart apache and it may work, or it may not.

RE: tomcat load-balancing maintenance strategy?
Yeah, but you still need to uncomment the cluster element in the server.xml. Also if you have a multi-homed server you need to bind multicast to a specific ip address. Not to mention that you need to set up mod_jk and apache to load balance. It is not just adding a trivial /distributable xml element into the web.xml that makes load balancing with session replication work.

The reason that this happens is that you are not using the right java. If you do a: whereis java You will see that java is installed in /usr/bin.

RE: Tomcat at Standalone
I will attempt to answer you questions as best I can. Your file structure of your site will typically look something like this $CATALINA_HOME/ webapps/ (PLACE YOUR WEBAPPS HERE) common/ lib/ conf/ Catalina/ localhost (CONTEXT DESCRIPTER GOES HERE) bin/ server/ Now your web application will be placed in the webapp directory. This will setup as follows: webapp/ someapplication/ pages/ Place all your jsp's here css/ Style sheets images/ images WEB-INF/ web.xml --- need to configure this classes/ --- application specific classes go here lib/ --- application specific jars go here Yes you can use tomcat standalone. If you are using a unix environment, port 80 is a priviledged port and you must either run tomcat as root (I do not recommend this), use jscv, or Mod_JK, or Mod_Proxy. By default, Tomcat runs on port 8080, but this can be changed to whatever you want. No more security issues than with any other webserver. You need to keep up on your patches/upgrades and monitor the security bulletins. Don't run it as root on a Unix box or Local System or Administrator on Windows. Sometimes it is easier to use the built in authentication mechanisms. That is why developers provided this stuffto save you time and effort. Tomcat provides a variety of login mechanisms. I would read up on them to see if they fit your needs. I hope that helps you out. It took me a while to figure all this stuff out and I still don't know a 1/3 of what I should.

Is this the normal configuration for this type of site? Are there known security issues with using Tomcat in standalone? The other piece would be Apache, if it is standard practice to use it even if you don't need to serve HTML pages.

RE: Tomcat Cluster
Apparently this was too verbose for anyone to read. I simply just don't understand why each tomcat instance is failing to recognize any other instance in the cluster. Multicast messages are being broadcasted. Is there any configuration parameter I can turn on that will verify that each tomcat instance can see the other instances??? Thanks, Randall -Original Message- From: Randall Svancara [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 23, 2005 9:44 AM To: Tomcat Users List Subject: Tomcat Cluster I have attempted to configure a tomcat cluster using version 5.5.7 of tomcat. I have configured a simple tcp cluster in the server.xml. I have two tomcat instances installed on two different Linux servers (Fedora core 3, IPTAPLES is turned off, there is not firewall). I have apache and mod_jk set up on a third server. Multicast is enabled!!!

No members active in cluster group. - The important thing to note here is that in the last line, I see INFO: Manager[/testapp], skipping state transfer. No members active in cluster group. At first I was thinking that multicast was not working properly. However, I was researching the Tomcat mailing list and found another thread discussing the same issue. I tried to use the tool, tomcat-replication.jar located on the CVS for tomcat. I can see the multicast sessions being generated between both servers using this tool. I also started up ethereal, the packet sniffer. I noticed that both servers are generating multicast packets. However after careful analysis of the packet information, I noticed that my servers were looking for 127.0.0.1/4001 for the receiver port. So I set the tcpListenAddress from auto to 10.111.22.163 This seemed to fix the problem with the multicast packets sending out the incorrect listener addresses. However, I am still getting the same error... INFO: Manager[/testapp], skipping state transfer. No members active in cluster group. So here are my questions: 1. Is this really an error, or is session replication working and I am not testing it properly? 2.What is the proper way to test that session replication is working properly? Can anyone provide me with code that works. I am currently using a bean that I declare with jsp:usebean scope=session.Is this wrong, should I use request.getAttribute(), request.setAttribute()instead. 3.Can session replication replicate things like a class that I implement as java.io.serializable?

RE: Tomcat Cluster
I used the tools that I downloaded from javagroups as described and I can send messages back and forth over multicast on 224.0.0.4 on port 45564 just fine. I am using the private address space of 10.111.22.x. My servers both contain one network card and each server defined as device eth0. Networking is working fine on each machine as I can ping to anywhere in the world. The only thing I can deduce is that I have a configuration issue that I need to figure out. Just a quick check list 1. Uncomment cluster elements in server.xml 2. Uncomment the replication valve in server.xml.I am assuming this is the valve that is listed in the cluster element in the server.xml. 3. Set all of you session attributes to implement java.io.seriazable 4. Tomcat instances are not on the same machine, so the tcpListenPort can be the same? 5. My web xml is set to distributable for my testapp web application. Possible problems that I have come up with include: Explicitly defining mcastBindAddress=10.111.22.167 when it is not necessary.

RE: Tomcat Cluster
Ok, I figured this out. Just so everyone knows in tomcat 5.5.7, the cluster multicast functionality is a little flaky (no offense to the developers who spent long hours figuring this stuff out). IF YOU DO NOT HAVE A MULTIHOMED NETWORK, YOU DO NOT NEED TO SPECIFY THE PARAMETER mcastBindAddress=10.111.22.167.

Tomcat Cluster
I have attempted to configure a tomcat cluster using version 5.5.7 of tomcat. I have configured a simple tcp cluster in the server.xml. I have two tomcat instances installed on two different Linux servers (Fedora core 3, IPTAPLES is turned off, there is not firewall). I have apache and mod_jk set up on a third server. Multicast is enabled!!! When I start up each tomcat instance I receive the following message in the catalina.out file. -- Feb 23, 2005 9:21:49 AM org.apache.catalina.cluster.tcp.SimpleTcpCluster start INFO: Cluster is about to start Feb 23, 2005 9:21:49 AM org.apache.catalina.cluster.mcast.McastServiceImpl setupSocket INFO: Setting multihome multicast interface to:/10.111.22.163 Feb 23, 2005 9:21:49 AM org.apache.catalina.cluster.mcast.McastService start INFO: Sleeping for 2000 secs to establish cluster membership Feb 23, 2005 9:21:51 AM org.apache.catalina.cluster.deploy.FarmWarDeployer start INFO: Cluster FarmWarDeployer started.

No members active in cluster group. - The important thing to note here is that in the last line, I see INFO: Manager[/testapp], skipping state transfer. No members active in cluster group. At first I was thinking that multicast was not working properly. However, I was researching the Tomcat mailing list and found another thread discussing the same issue. I tried to use the tool, tomcat-replication.jar located on the CVS for tomcat. I can see the multicast sessions being generated between both servers using this tool. I also started up ethereal, the packet sniffer. I noticed that both servers are generating multicast packets. However after careful analysis of the packet information, I noticed that my servers were looking for 127.0.0.1/4001 for the receiver port. So I set the tcpListenAddress from auto to 10.111.22.163 This seemed to fix the problem with the multicast packets sending out the incorrect listener addresses. However, I am still getting the same error... INFO: Manager[/testapp], skipping state transfer. No members active in cluster group. So here are my questions: 1. Is this really an error, or is session replication working and I am not testing it properly? 2.What is the proper way to test that session replication is working properly? Can anyone provide me with code that works. I am currently using a bean that I declare with jsp:usebean scope=session.Is this wrong, should I use request.getAttribute(), request.setAttribute()instead. 3.Can session replication replicate things like a class that I implement as java.io.serializable?

RE: Need your expertise on lb worker
Mod_JK used in conjunction with Apache Web Server will provide you with load balancing functionality. You only need two tomcat instances. Here is a simple diagram. This provides a conceptual view of how load balancing is networked. See that there are only two tomcat instances needed. Of course you could have more, if needed. Tomcat Instance 1 | Apache and Mod_JK --Router | Tomcat Instance 2 So the answer is NO. I would look at this website for documentation on how to configure load balancing with mod_jk configuration. http://jakarta.apache.org/tomcat/connectors-doc/config/workers.html I would also check Google for documentation as well.

Do I need to set up a SEPARATE Tomcat instance as the load balancer worker or is it handled by JK connector?

RE: Speed issues with SQL Server 2000 and JTDS
Try pinging the server with Microsoft SQL Server from the server running
tomcat. You might
use a traceroute to see where the network bottleneck may exist.
What are your ping times. Are you experiencing network latency? Are
you going through a
Firewall? I am using JTDS and I have not experienced any problems with
it.

Trying a few test should help you narrow things down a bit.
1. Run without DB connection. (Done runs fast)
2. Run with a DB connect but no query. (Done runs slow)
3. Run with a simple query and do nothing with it.
4. Run with a simple query and post results in page. Only move forward
through result set.
5. Run with a simple query and post results in page. Move around in the
result set (Only if you do this in your page).
At some point in these test you should see a dramatic jump in the
response time. If it is a steady climb, then you may have multiple
issues.
Report back what you find and we'll make suggestions from there.

RE: Please help...
Tomcat is organized differently than Apache. First of all Apache has a document root, where you can put all of your php and html files in. With tomcat, the directory structure is different. If you want to get started with tomcat, I suggest first creating directory under the webapps directory of your tomcat installation. For this example, lets call it test. Under test we will create a WEB-INF directory. The WEB-INF directory contains basically the configuration file for your web application you will be creating in the test directory. In the WEB-INF folder, create a file called web.xml. So at this point you should have directory structure that looks like this. Test WEB-INF web.xml Now edit the web.xml file to contain the following: ---snip ?xml version=1.0 encoding=ISO-8859-1? !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN http://java.sun.com/dtd/web-app_2_3.dtd; web-app display-nameA test web application/display-name description Your test web application /description /web-app ---snip Now that you have an empty web application container set up, add some jsp files. Keep in mind that everything under the WEB-INF directory is protected by tomcat. You would not want someone to browse through your configuration now would you? For simplicity sake, lets create a test jsp page now. Create a file called index.jsp directly under the directory test. This is what your directory structure should look like now under your test directory: Test index.jsp WEB-INF web.xml Lets add some content under your test.jsp. We will combine some html with java code to demonstrate how things work. [EMAIL PROTECTED] contentType=text/html% !-- page directive -- [EMAIL PROTECTED] pageEncoding=UTF-8% html headtitleYour first cool page/title/head body %out.println(Hello world)% !-- jsp code -- /body /html Ok, make sure you have tomcat started. On windows, go to services and see if the service is running. On linux, type ps -ef or ps -aux on unix. If it is not running, you need to start this service for your platform. Next, browse to the machine where you have tomcat installed. It might be on the same machine your programming on. http://localhost:8080/test/ You should see hello world now. By default, Tomcat runs on port 8080. You must specify the port number in your browser. You can configure Tomcat to run on port 80 if you wish, but that is out of the scope of this document. Oops, I just read you are using fedora core. I am using fedora core. I have apache and tomcat set up to talk to each other using mod_jk2. I can send you my configuration files if you wish. I hope this was not too basic for you. Randall -Original Message- From: Ken Keefe [mailto:[EMAIL PROTECTED] Sent: Friday, November 12, 2004 1:14 PM To: [EMAIL PROTECTED] Subject: Please help... I have been struggling with Tomcat for several days and I am at the end of my rope. If I come across as irritated, I apologize in advance. I simply want to learn how to write JSP. I have a book and I want to start working through it, but I am having trouble setting up a server to serve JSP. I currently run Apache to serve HTML and PHP. Ideally, I'd simply like Apache to start recognizing JSP and handling it appropriately. Unfortunately that seems to not be an easy task... I have tried using mod_jk to connect Tomcat and Apache, with no luck. I finally gave up on trying to use Apache and I was just going to keep them separate. Now, how do I tell Tomcat to serve my jsp files??? I tried using the manager web program to add an application pointing to the correct directory, it accepts the command, but nothing is added to the application list and it doesn't serve the content like I expected it to. Finally I said screw it, I'll simply put my experiment files in the document root of Tomcat and use that for now. Still no luck, it serves up the same default stuff, even when I rename the file. My environment is the following: Fedora Core 2, Apache 2.0.51, Tomcat 5.5.4, JDK 1.5.0. Ideally I'd like to do what I talked about earlier, having Apache automagically know what to do with *.jsp files. However, I'll take what I can get! Thank you very much in advance. I can't explain how damned aggravating this whole thing has been.

RE: address is already in use
I have noticed that sometimes when you shutdown tomcat on linux, it seems to take a long time to close down everything. If you restart tomcat while the old instance is trying to shut down, you will recieve this error. So by restarting, you might not be aloting enough time for the tomcat instance to completely shut down.

RE: address is already in use
Try: yourserver# killall -9 java -- kills all java processes with extreme prejudice yourserver# /etc/init.d/tomcat start -- assumes you have a startup script for tomcat, otherwise use the scripts in the bin directory of your tomcat install. That will remove all the java processes running on your unix system. Or you could go into task manager in windows stop all the java processes. Keep in mind this could kill other processes that are using java too. Anyway, this has worked for me. If there is a better way, I would like to know.

Subject: JNDI / pooling
Hi,
I can't describe exactly the problem because I'm not familiar with all the
terms... But the big picture is that I want to create a pool of ftp
connections to work like a database connection and I want to get the
connection from JNDI.
So far I extended BaseKeyedPoolableObjectFactory and StackKeyedObjectPool
and it works fine like this:
FTPConnectionPool pool = new FTPConnectionPool();
String key = key;
try{
FTPClient ftp = pool.borrowClient(key);
if( ftp.sendNoOp() ){
System.out.println(OK);
}else{
System.out.println(NOPE);
}
pool.returnClient( key, ftp );
}catch(Exception ex){
ex.printStackTrace();
}
But I want to make it work from JNDI almost like a datasource
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource)
ctx.lookup(java:comp/env/jdbc/backup);
Anyway I am completely lost if it can be done or not.
So far I get an exception when I try to start Tomcat:
GlobalResourcesLifecycleListener: Exception processing Global JNDI Resources
javax.naming.NamingException: Could not create resource factory instance,

RE: How to detect tomcat down
Write a perl script using the perl::LWP module from cpan. You could even get really complex and write some output to a web page that tells you how memory is being used, store that information into a database for statistical reporting purposes, in addition to emailing/paging the system administrator that problems might be occuring. You could easily figure out which ones are down by the lack of a response. No request, server must be down, do something!!

RE: Question about memory
Ok, I went back an re-read your originaly post. I think elsewhere in the forum there is mention of top not accurately displaying the amount of memory java is using. Here is a blurp i found searching through google for memory top and tomcat: There is a difference between the total amount of memory used by your Java applications (Tomcat + installed apps) and the JVM as a whole. Your applications live in the heap. You can write a trivial Java application that prints out the total memory used in the heap (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory()) to verify that your heap doesn't exceed your max setting. The JVM itself has a footprint in memory that adds to the total memory footprint in the OS. Supposedly tomcat 5 has a status page that displays memory usage. That might be more accurate.

On Friday we just moved out datacenter to a new location. However we see this problem even internally at the location so I don't believe it is any sort of routing issue (and the problem didn't start until Tuesday). 2. The clock on this webserver was many hours off. On Tuesday (yes, the day the problems started) the clock was synchronized and the timezone correctly set so the machine now has correct time. This seems to be the most probable cause simply because it happened around the same time, but I just can't understand why or how. 3. Yesterday we rebooted the box to see if that would help. It did. We didn't have any more problems at all that day until this morning we see the problems again. Today we recycled just tomcat and that seems to have fixed it as well, though I expect that by tomorrow I will see the problem again. 4. I wouldn't think this could have anything to do with that new Sasser worm, but listing that just in case. The machine is running Linux kernel 2.4.20-8 with httpd-2.0.40-21 and jakarta-tomcat-5.0.18.

RE: mod_jk hangs
Well, that depends on what platform and how apache was compiled. As I understand on windows, apache uses the mpm modules and unix it uses forking or it can use mpm. You need to find the section for you platform and make the ajustments as neccessary. Below is the section where you need to look in your apache configuration file, usually called httpd.conf, but i have seen them named apache.conf (gentoo anyone). But you can see the min and max spare servers/threads listed in each section. Just adjust accordingly. I hope this helps.

It is almost the same, except I had context xml configuration files stored in the webapp directory for the webapps.

RE: Apache+Tomcat + MOD_JK on different machine
Your workers.properties should be on your webserver where apache is located. I typically place the workers.properties in the same directory where httpd.conf is located. workers.properties is needed for mod_jk so it makes sense that it needs to be in the same machine where mod_jk and apache are installed. At least far as I know anyways. Sometimes apache has a difficult time finding it. I have used this line to tell apache where to find the workers.properties. You might try including a line like this in your apache configuration file: IfModule mod_jk.c JkSet config.file /etc/apache2/conf/workers.properties Include /etc/apache2/conf/mod_jk2.conf /IfModule If anyone else has anything to add to this or correct me on, please feel free because I am still learning to, but then again who isn't??

RE: Tomcat 4.1.29 CoyoteAdapter Exception
Thanks, I have had a difficult time reproducing this error on a predictable basis. All I can say is that it happens once per day, and I have temporarily wrote a perl script that checks the service to see if it is working properly, and if not, it shuts down tomcat and restarts it...A bandaid fix at best. I will give you a little more background on the webapp I have deployed. It is just a basic webapp with several jsp pages and a couple of servlets. I am using Database Connection Pooling with Mysql Connector J. The problem does not appear to happen on any one particular jsp or servlet, but I will keep digging further to see if it is or not. If I can create a reproducable test case, I will post it here. I will keep on researching the problem to see if I can pin point the exact error. Thanks for the advice on using news groups.

Ok, now I am thinking this error might be caused by Database Connection pooling. I increased Mysql's max connection limit from the default to 500. I hope this enough to satify my hungry application. Also I adjusted the apps xml configuration option maxActive to a value of 400 which is 100 less than the max.

RE: Tomcat 4.1.29 CoyoteAdapter Exception
After further investigation, I am just going to chalk this one up as a stability issue with windows XP. The same version of tomcat running with same configuration on linux can sustain well over 1+++ hits using jmeter while the same configuration on windows barely handles 2000 hits before tomcat fails. Anyone know of a stable version of tomcat that works with windows. Do I need to downgrade to 4.0.x or upgrade to 5.0.x versions of tomcat for better stability on windowsor do I need to convince my boss what I have know all along, linux is superior to windows.

RE: Tomcat 4.1.29 CoyoteAdapter Exception
What would cause the coyote connector to return a null pointer exception. Every time this happens, mod_jk is unable to communicate with tomcat and as a result our web service is unusable. Is this a tomcat bug, or a problem with running tomcat on Windows XP. Anyway, I have looked through this user group and found some other people with this problem on Solaris, but no real answers. Thanks. I am running tomcat 4.1.29, apache 2.0.48, with mod_jk configured on Windows XP.

RE: Apache/Tomcat/Struts Certification Proposal
I found your comment on certifications insightful. What if you had two experienced engineers, but only one of them had a ASF certification?? Which one would you hire? Thanks, Randall -Original Message- From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Sent: Friday, February 20, 2004 11:12 AM To: Tomcat Users List Subject: RE: Apache/Tomcat/Struts Certification Proposal Howdy, My person view on most of these certification is that they're BS. They mostly tell you someone knows the nomenclature and has read some books. They're no substitute for experience, and when (this is not an if, I've actually been in this situation) I have to choose between a less experienced but certified engineer and a more experienced non-certified one, I go with the latter. I've been happy with my choices in this area so far ;) Most certifications also require the certified person to renew/retest periodically, which is a pain, albeit required otherwise the certificate certifies out-of-date/obsolete knowledge. But this hassle has been enough to keep my from getting certified in the past, and is likely to do the same in the future, including for ASF certification if one were offered.

It's just not fair for people with better understanding of the software(I believe you can get a IIS certification, why not Apache). And it would help the Apache Foundation as well. With the money they get from people taking the exams, they can have way better support as a whole. After all, software programming is not only about working in front of a computer all day anymore. The real challenge is how the whole process can be administrated. Ah, I don't think it's possible anyways with current open source development structure. But just thought it would be an interesting idea. -Yan -Original Message- From: Adam Hardy [mailto:[EMAIL PROTECTED] Sent: Thursday, February 19, 2004 1:35 PM To: Tomcat Users List Subject: Re: Apache/Tomcat/Struts Certification Proposal FWIW, I think certification is a waste in terms of the amount of learning that it forces on the developer. Perhaps in many cases it does help the recruiter, but firstly I think that recruiters who need to see certification of something in an IT candidate are not doing their job properly, and secondly I think the whole process is a waste of resources, siphoning off money and time from people who usually have better things to do. So please, no to Apache certifications!

I am wondering what the following configuration directive accomplishes for tomcat 4.1.29 in the server XML file when added right below the line with Server port=8005 shutdown=SHUTDOWN debug=0. Listener className=org.apache.ajp.tomcat4.config.ApacheConfig modJk=C:/ApacheGroup/Apache2/modules/mod_jk.dll / Also I am currious to know what the following configuration directive accomplishes under the host container in the server.xml file.

Thank you, Randall If memory serves, those directives are to help automatically generate the necessary apache-related JK config stuff. (When using mod_jk to connect tomcat to apache, you need to add some stuff to the apache config file.) You might notice an extra file there, perhaps called something like mod-jk.conf (and not sure if it generates the workers.properties), which supposedly can be included (directly or indirectly) in the apache config file. I say supposedly because I seem to recall that the config stuff it generated, while certainly helpful, wasn't always 100% complete/correct, and usually needed to be modified a bit to work.
