Many hosts sharing servlets
I am moving from jserv to tomcat. I have 100+ servlets and classes that I want to be available to up to 100 virtual hosts. The server I am moving to runs RHE3 with Apache2, Plesk and Tomcat4. Plesk only supports the mod_webapp connector. I can't find much info on mod_webapp but it seems to me that each virtual host must have its own webapps deployed. So I have tried to put all the classes into /var/tomcat4/shared/classes. In each host, I deploy a servlets.war file that contains only the following WEB-INF/web.xml file - ?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-nameGlogal servlets/display-name description Global servlets. /description servlet-mapping servlet-nameinvoker/servlet-name url-pattern/*/url-pattern /servlet-mapping /web-app This is working on the few hosts I tried so far. I can link to a servlet using http://a-host.com/servlets/MyServlet. Questions Is there a better way to do this ? Will tomcat be using hugely more memory than jserv was ? Should I abandon Plesk, use Cpanel and configure apache/tomcat manually (but I don't want to have to ssh in and configure each new host manually) ?

Re: All threads (250) are currently busy
I don't know what kind of application you are running, but most likely you have a resource leak; Do a thread dump and see what your threads are waiting for. Most likely they are just in wait state and no CPU usage. It could be cause by lots of things. One problem could be using jdbc and not closing your connection or returning it to your pool. For testing reduce your resource limit, don't increase it (reduce Max thread, and connection pool). This would cause system hangs faster. Send a SIGQUIT signal to VM and look at state of your threads and its location (don't post your thread dump!)

Tomcat 5.5.9 Connection Pool / JNDI / DBCP
Hi.
I have some problems with Tomcat 5.5.9 Connection Pooling / JNDI / DBCP
When running my java component (se below) I receive this NamingException:
/NE: Need to specify class name in environment or system property, or as
an applet parameter, or in an application resource file:
java.naming.factory.initial/
If I add this code:
System.setProperty(java.naming.factory.initial,
org.apache.naming.java.javaURLContextFactory);
System.setProperty(java.naming.factory.pkgs, org.apache.naming);
to the constructor in the java component, I receive this exception:
/NE: Name java: is not bound in this Context/
What is wrong and what is the solution to the problem?
Thanks
Lars Nielsen Lind

Better depends on your goals, but most a lot of people would say that using the invoker has its pros and cons. Mostly cons. =) (See the archives for why.) You could just JAR up the 100+ servlet classes and drop them in each webapp's WEB-INF/lib. Next, write something to create a set of proper servlet/ and servlet-mapping/ entries for those servlets. This is a one-time hit that will pay off long-term. : Will tomcat be using hugely more memory than jserv was ?

Re: Tomcat 5.5.9 Connection Pool / JNDI / DBCP
You should be doing this in your code:
Context initContext = null;
try {
initContext = new InitialContext() ;
} catch ( Exception e1 ) { //... do something with the trapped exception }
try {
DataSource ds =
(DataSource)initContext.lookup(java:/comp/env/jdbc/testdatabase);
} catch ( Exception e2) { //... do something -- log it }
// Store a reference to ds someplace where it can be used over and over
and over.
Note the only thing I really changed is to make the type of initContext
Context instead of InitialContext. This is mostly straight from the
Tomcat 5.5 JNDI docs located here:
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-resources-howto.html

Hi.

Re: Can't get Tomcat to use account other than System
In addition to Logon as a service, the account will also need to Act as part of the operating system. Again, these are the two minimum requirements. Depending on what you're trying to access, you may need to assign additional user rights. Darryl --- Mark Leone [EMAIL PROTECTED] wrote: Thanks. That's useful information, but unfortunately it didn't solve my problem. The account I'm trying to use was already mapped to the Logon as a Service right. I looked at all other rights that didn't have either the account or its group mapped to them, and I couldn't see any that seemed to be needed. I searched through the MS knowledge base as well, and didn't find anything relevant to this problem. I found a better way to accomplish what I was trying to do; but I'd like to find out why I can't run Tomcat as an account other than System, in case I have a need for it at some later point. Thanks for trying. Darryl Wilburn wrote: In Administrative Tools, go to Local Security Policy and navigate to Local Policies User Rights Assignment. This lists all the assignable user rights. At the very least, this account will need to be assigned to Logon On as a Service. Don't mess around with the Net Logon service. The only service you need to mess with is Apache Tomcat. The other services aren't broken, so don't try to fix them.

The only options I can find for defining account properties are in Control Panel -- Users and Administrative Tools -- Computer Management; and neither of those have any settings beyond very basic things like Admin vs. limited priviliges.

I specified the desired account credentials in the Log On tab of the Service Properties, and then when I tried to start the service I got the following error.

The credentials seem to be accepted, but if I close the Service properties window and re-launch it, the Log On tab has reverted to its default configuration, i.e. Log on as Local System Account is enabled instead of the account I specified.

Yet, they are configured properly and the jk log shows that it finds them: Well, just try the worker names without a colon. The reason for why we are forcing the alnum chars only is because the special chars needs to be url encoded if the client does not support the cookies. So it's easier and safer anyhow to rename the jvmRoutes in server.xml. Also for jkstatus. If you are calling that from some virtual host, you will need to have 'JkMountCopy On' directive in root, or define the Location in that virtual host. Also any workers.propeties directive should not exceed the 1024 chars. Regards, Mladen. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Running two tomcat in the same time
Hello All, I have a question but before that let me give you a brief about our setup: We have tomcat 5.0.24. It is installed on Solaris 8 under user root using the port 80; we installed another tomcat instance under different directory and different user (username: tomcat) and new port 8080. The problem is we couldn't run both of them in the same time, if we start one of them the other one will stop???!!! Do we have to do any customization in the configuration??

Heap not expanding beyond -Xms512m
Hello Tomcat-oids, I'd really appreciate any help with this...Thanks in advance. We've been running performance tests against Tomcat 4.1.26 on Linux and Windows. We've tuned heap sizes to -Xms512m -Xmx1024m. Monitoring the JVM memory usage with a daemon thread calling Runtime.getRuntime().freeMemory() / totalMemory() / maxMemory(), we've noticed memory was never expanded beyond 512MB. Instead, when usage was getting close to 512MB, we could see the garbage collector kick in. We never got OOM errors. Can anyone share experiences about this? Do I have to use -Xms1024m -Xmx1024m (which seems to defeat the purpose of having ms and mx...)?

RE: Heap not expanding beyond -Xms512m
This is expected behaviour. The heap will not grow if the memory required can be gained through a garbage collection. The heap will only grow if after a garbage collection it still cannot allocate the required memory or is over a certain percentage (I forget what the default is). I would suggest that you don't in fact need 512MB if your app runs fine with no OOM in 512MB. If you really want to use the full 1GB the you'll have to use -Xms as you suggested.

I agree, it's always a good idea to let the JVM do what it is supposed to do instead of creating a growing overhead.

RE: using manager with apache virtual host
# # Based upon the NCSA server configuration files originally by Rob McCool. # # This is the main Apache server configuration file. It contains the # configuration directives that give the server its instructions. # See URL:http://httpd.apache.org/docs-2.0/ for detailed information about # the directives. # # Do NOT simply read the instructions in here without understanding # what they do. They're here only as hints or reminders. If you are unsure # consult the online docs. You have been warned. # # The configuration directives are grouped into three basic sections: # 1. Directives that control the operation of the Apache server process as a # whole (the 'global environment'). # 2. Directives that define the parameters of the 'main' or 'default' server, # which responds to requests that aren't handled by a virtual host. # These directives also provide default values for the settings # of all virtual hosts. # 3. Settings for virtual hosts, which allow Web requests to be sent to # different IP addresses or hostnames and have them handled by the # same Apache server process. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with / (or drive:/ for Win32), the # server will use that explicit path. If the filenames do *not* begin # with /, the value of ServerRoot is prepended -- so logs/foo.log # with ServerRoot set to /usr/local/apache2 will be interpreted by the # server as /usr/local/apache2/logs/foo.log. # ### Section 1: Global Environment # # The directives in this section affect the overall operation of Apache, # such as the number of concurrent requests it can handle or where it # can find its configuration files. # # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # NOTE!

Launching an embedded Tomcat from Maven 1.x
Hi there!
I'm working to embed a Tomcat server as a servlet container inside an
Avalon Framework with a Loom engine. I looked for information how to
launch the Catalina service from Java and finally I wrote the next
file:
package org.jlabase.framework.tomcat.startup;
import java.io.File;
import java.net.InetAddress;
import org.apache.catalina.*;
import org.apache.catalina.connector.*;
import org.apache.catalina.realm.*;

import org.apache.tomcat.util.*;
import org.jlabase.framework.tomcat.*;
/**

*/
public class TomcatImpl implements Tomcat {
private String path = null;
private Embedded catalina = null;
private Host host = null;
private Context rootContext;
private int port = 8080;
public String getPath() {
return path;
}
public void setPath(String value) {
path = value;
}
public int getPort() {
return port;
}
public void setPort(int value) {
port = value;
}
public void start() throws Exception {
Engine engine = null;
// Create an embedded server
catalina = new Embedded();
catalina.setCatalinaHome(getPath());
// Set the MemoryRealm
MemoryRealm mr = new MemoryRealm();
catalina.setRealm(mr);
// Create an engine
engine = catalina.createEngine();
engine.setDefaultHost(localhost);
// Create a default virtual host
host = catalina.createHost(localhost, getPath() + /webapps);
engine.addChild(host);
// Create the ROOT context
rootContext = catalina.createContext(, getPath() +
/webapps/ROOT);
rootContext.setReloadable(false);
rootContext.addWelcomeFile(index.jsp);
host.addChild(rootContext);
// Create the Manager context
Context managerCtx = catalina.createContext(/manager,
getPath() +
/webapps/manager);
managerCtx.setPrivileged(true);
host.addChild(managerCtx);
// Assemble the container hierarchy
catalina.addEngine(engine);
// TODO Repair the Connector bug
String addr = null;
Connector connector = null;
InetAddress address = null;
try {
connector = new Connector();
connector.setSecure(false);
address = InetAddress.getLocalHost();
if(address != null) {
IntrospectionUtils.setProperty(connector,
address, address.toString());
}
IntrospectionUtils.setProperty(connector, port, new
Integer(getPort()).toString());
}
catch(Exception e) {
e.printStackTrace();
}
connector.setEnableLookups(false);
catalina.addConnector(connector);
catalina.start(); // Starts the embedded server
}
public void stop() throws Exception {
catalina.stop();
}
public static void main(String args[]) {
System.out.println(Creating server instance...);
TomcatImpl tomcat = new TomcatImpl();
tomcat.setPath(
new File(System.getProperty(jlbframework.tomcat.home,
System.getProperty(basedir,
.))).getAbsolutePath()
);
try {
System.out.println(Using CATALINA_HOME = +
tomcat.getPath());
System.out.println(Starting server on port +
tomcat.getPort());
tomcat.start();
//tomcat.catalina.setAwait(true);
}
catch(Exception e) {
e.printStackTrace();
}
}
}
My intention is to configure the Catalina service from this class and
use a simple Ant-like script in Maven to launch the main method of
this class. So, my next step was write the maven.xml file, this is:
project xmlns:ant=jelly:ant xmlns:j=jelly:core
xmlns:u=jelly:util default=loom:sar
goal name=jlbframework:tomcat-init
ant:path id=tomcat.classpath
j:forEach var=artifact items=${pom.artifacts}
j:set var=dependency value=${artifact.dependency} /
j:if test=${dependency.getProperty('sar.bundle')=='true'}
Re: All threads (250) are currently busy
It doesn't matter what platform your running on. On linux you can use kill -s SIGQUIT pid on window box if you have cygwin you can do the same and if you do not just do a google search and there are lots of C code that does that, you can look at signal.h or sites like http://www.csl.mtu.edu/cs4411.ck/www/NOTES/signal/kill.html has actual code for you. I haven't tried their code, but I used to have one myself. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: OutOfMemoryError - 100 thread limit?
This is not a memory leak in the application - we have hooked up a profiler to the application and watched the actual memory usage when causing this issue to happen. We have lots of memory available, are nowhere near the Xmx limit, and the machine has lots of memory available over and above the Xmx limit. In fact, I can cause the error to happen every single time, simply by hitting the first web page (login page) of the application - I don't have to log in, or do any work. All I have to do to get the error to happen is hit 18-19 different instances of the web application, watch the Active thread count go up to 100 and tip over the tomcat. We've gone through all of the suggested infomation out on the web - we've tweaked the Xms, Xmx and Xss parameters - none of these changes made any difference, since we're not actually running out of memory. I've reproduced this on 3 different machines, all running Red Hat Linux ES 3.0 - both with LD_ASSUME_KERNEL 2.4.19 and without, so the Linux threading model doesn't seem to affect the problem.

RE: jk 1.2.10 + apache 1.3 issue
Why have worker.list? The goal of the worker.list is to publish a worker to make it available to JkMount, correct? Why not have: worker.jvmRoute.type=ajp13 worker.jvmRoute.host=10.0.0.1 worker.jvmRoute.port=8009 worker.jvmRoute.mountable=1 And then construct the available workers for jkmount after the initialization of each worker, eliminating the worker.list altogether? Thanks for the response. I haven't found the issue yet. There is no VirtualHost setup on this particular server. I had changed JK1 to allow for long worker.list lines by increasing the LINE_LENGTH to 4K. This worked just fine under Apache 2 and we haven't seen any issues in the JK1 code or cookies with respect to the ':' in the JVM Routes. To you it might seem easier to change the jvmRoute, but unfortunately there are literally 100's of production app servers that would need changed and restarted. It wouldn't be easy at all and would require every app to be retested- which is quite a task with this many applications. We face some large scale problems that most users of tomcat/jk don't see because we have so many applications. I'm going to try loading the same jk config files on an apache 2 build of JK1 and see if I have the same issues- if so then I'll know its somewhere in my config. If not, then I'll know that there is some difference in behavior between jk1 on apache 1.3 and apache 2.0. As I mentioned before, the error I saw in the logs NULL factory for ajp13*ajp13 makes me believe there was a problem during parsing of the config since I never explicitly specify ajp13*ajp13 as a value anywhere. So perhaps the modified LINE_LENGTH of 4K works fine with apache 2, but runs into issues on Apache 1.3.

Allow from 127. /Location /IfDefine As you can see from my previous posting, not even jkstatus works, nor do any workers. Yet, they are configured properly and the jk log shows that it finds them: Well, just try the worker names without a colon. The reason for why we are forcing the alnum chars only is because the special chars needs to be url encoded if the client does not support the cookies. So it's easier and safer anyhow to rename the jvmRoutes in server.xml. Also for jkstatus. If you are calling that from some virtual host, you will need to have 'JkMountCopy On' directive in root, or define the Location in that virtual host. Also any workers.propeties directive should not exceed the 1024 chars.

Re: OutOfMemoryError - 100 thread limit?
We have no jsps in the application. The index.html page loads our servlet class, and I've put logging of active number of threads at the beginning of the servlet ini() and the very end of the service() methods in that servlet class. The application initializes, but we aren't doing any of the real work of rendering dynamic pages or talking to the database at this point. I get the same results whether my Xmx is 84 megs or 512 megs - we're just not using that much memory.

Re: OutOfMemoryError - 100 thread limit?
No, unfortunately, changing those options doesn't seem to make any difference either.

Re: OutOfMemoryError - 100 thread limit?
that is some really odd behavior coming from Tomcat. I've probably run over 1K benchmarks on Tomcat over the last 3 years and I've yet to see that kind of behavior. Here are some random ideas to try, which I've used in the past. They may not help, but I figure it wouldn't hurt to suggest them. use jmeter to send 250 requests with 25 threads against the index page. then view the status in tomcat 5.5.4. Over time, you should see the number of threads drop to the minimum. Under normal conditions, tomcat will create enough threads to service those threads. after a few minutes, the thread count should drop. If it doesn't, it means something is keeping the connection open. if you see that, it is most likley an application bug. Another idea is to do netstat and see what the status of the connections are. It might be some of the connections are not closing. peter On 4/20/05, LeeAnn Pultz [EMAIL PROTECTED] wrote: We have no jsps in the application.

Re: Apache_MaxClients, AJP_maxThreads and jkWorker.cachesize
cachesize is used only for threaded apache's like 1.3 on windows or netware; apache2 with worker_mpm, etc... The size must reflect the number of threads per child process that for prefork mpms like 1.3 on unixes is always 1, so there is no need to set it. Each apache instance needs it's own shared memory. 2x150=300/3 in ideal case, so each TC should have 100 maxThreads. If you expect that one of the Tomcats in the cluster can fail, then the number should be 300/2 or 150. Regards, Mladen.

Re: OutOfMemoryError - 100 thread limit?
We did run some code that just makes threads, on the machine and it had no effect - I'll incorporate that code inside a servlet, so we can do this test against tomcat and see if it makes a difference. We just tried the same test against tomcat 5.0 using port 8080 and not using any of the mod_jk connectors, to see if that made a difference - we found that we started with more active threads by uncommenting that section of server.xml (started with 67 active threads rather than 44) and got a bit higher (died at 118 threads rather than 100 threads) so I'm taking that result to show that the actual number of threads allocated to the application remained about the same, with or without the usage of mod_jk.

Re: Can't do logout in basic authentication
In most applications this is one of those *perceived* problems that corporate users get uptight about. The best way to prevent abuse of an idle authenticated browser window is a screensaver with password lock -- as it protects the rest of the computer, the documents thereon, etc. The only really good case for a logout is where you have a shared computer with many different users coming and going -- and all using a single guest account on the client itself rather than separate logins. In this case a logoff button that closed down the browser would not be a half bad idea :-) -- Jess Holle P.S.

Re: Per Application JNDI/JDBC Configuration
Yep. This is basically the direction I was already headed. Once I deploy my application I do get the JNDI name in the list of DataSources (as viewed from the Administration tool), but the data source has no parameters. It almost looks as if Tomcat's loader is ignoring the ResourceParams tag. My context.xml file is in the META-INF directory just under the document base directory. Parsons Technical Services wrote: For each app you have running you will need a context element in a xml file. This should reside in the war. In this file you can setup the resource which will be available only to that app. This will still give you pooling. If you follow the instructions on the Tomcat site for the JDBC How-To that will set things up. The only change is to put the elements in with the context fragment in the xml file for your app instead of the server.xml. Yeah the web site should be changed considering that the preferred way to set up app is not to put anything in the server.xml and yet this How to has you do just that. Eventually they will get to it. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Can't do logout in basic authentication
P.S. Freeing one's *session* on leaving works with any type of authentication and makes sense in many cases -- it's just harder to communicate this concept to the user... Jess Holle wrote: In most applications this is one of those *perceived* problems that corporate users get uptight about. The best way to prevent abuse of an idle authenticated browser window is a screensaver with password lock -- as it protects the rest of the computer, the documents thereon, etc. The only really good case for a logout is where you have a shared computer with many different users coming and going -- and all using a single guest account on the client itself rather than separate logins. In this case a logoff button that closed down the browser would not be a half bad idea :-) -- Jess Holle P.S.

Re: OutOfMemoryError - 100 thread limit?
This was first reported when we had multiple web applications running on one tomcat, and a user would be logged into the site and be using the application fine, and then if another user started working in a new site, they would get the OutOfMemory error when the first tried to load the page of their site. The first user would then start getting exceptions once the OutOfMemory error happened. When we reproduce the error, it doesn't seem to make a difference whether we simply click through a list of links, opening each site in a new window quickly, or whether we pause a few seconds in between opening new sites. So it doesn't necessarily *seem* to be dependent on multiple people firing up their sites at the same time, or over the course of several hours as different people use the system. We've identified that each instance of our application starts up with 3 active threads - we have a monitoring thread, the application thread and the user's current thread. When I start up tomcat, and hit the first site, I see about 44 active threads to start with - this seems to be affected by whether we have the Http10 connector commented out, whether the management port is set up etc. If I run the application through Jbuilder + tomcat, the active count doesn't count the tomcat' threads, and I start with 3 threads and increase by 3 threads for each new application I open in my browser, the first time.

RE: jk 1.2.10 + apache 1.3 issue
The problem was a duplicate worker entry. Apparently, in JK2, duplicates were ignored. I've written a perl script that converts the JK2 config to a JK1 config because of the large number of entries- I'll just need to have it validate that there are no duplicate workers. Jk1 should probably handle this failure mode a little different- like with a 'duplicate worker' message/test. If it were as easy as a global search and replace on a single system, then I'd have no problem doing it. If I were at liberty to go into the details of all the impacts such a simple change causes at a megacorporation, you'd understand why its such a big deal. Its a huge/costly chain of events. Lets just say I'd be writing patches for Apache httpd long before we'd make such a change across all the servers because the overall cost per change is far less. Imagine coordinating 20 or more teams to test hundreds of applications because of strict change control procedures. Substituting the value in all of the files is the easy part... Thanks for the responses though. Is there a separate mailing list for jk1 development where I should post the suggestion to add a simple test/error message when parsing a duplicate worker?

Re: OutOfMemoryError - 100 thread limit?
We tried a new test :) We added code that spins up 8 threads inside just a plain servlet that doesn't do anything else. When I fire up 10 different instances of that servlet, I get hundreds of threads printing out as being active - and no out of memory errors.

Tomcat SSO with other web servers

Re: OutOfMemoryError - 100 thread limit?
if your application is thread heavy, I would recommend changing it so that one thread can manage several processes. creating 800+ threads is going to hit a scalability and reliability wall very quickly. In general, you want to make sure the number of threads remain constant under constant load. If it doesn't the server will eventually crash as you currently see. I'm guessing the application is using threads to handle async processes, which is good, but spawning new threads with every request isn't going to work. hope that helps peter On 4/20/05, LeeAnn Pultz [EMAIL PROTECTED] wrote: We tried a new test :) We added code that spins up 8 threads inside just a plain servlet that doesn't do anything else.

Re: localhost Context files and path = /
This is not allowed in Tomcat 5.5.x http://jakarta.apache.org/tomcat/tomcat-5.5-doc/config/context.html Do not declare the path if the path is null or / in the context unless you are doing a static in the server.xml With that in mind think about the fact that there is already a context element in the server.xml This is the context element for the app you are trying to deploy. Modify it to suit your needs. Unlike the others that are declared in the war, the context for the ROOT app is in the server.xml and nowhere else.
