Re: In-Process Tomcat
On 6/25/07, lightbulb432 [EMAIL PROTECTED] wrote: Thanks for your detailed response. See questions below. In-process Tomcat is to have Tomcat running in the same process space as Apache HTTPD, IIS, or other web server. Since most of the web servers are implemented in C/C++, you will have to use JNI to integrate with Java-based Tomcat, and create a mod_tomcat like module for Httpd. So there's no standard prepackaged installation of the two combined, or no standard connector plugin or something that's distributed with either Tomcat or HTTPD, which is why I'd have to create it myself? Is the in-process approach that uncommon? personally i never heard of anyone using it. Definitely the in-process setup improves performance, since communication between Tomcat and web server occurs via memory-based data exchange. It will be less stable since if something went wrong with the Tomcat, it would affect the web server directly. It will also be less scalable, since this setup won't support high-availability and clustering of Tomcat servers. Why does the in-process approach render high-availability and clustering impossible? From a technical/implementation perspective, what is it about the in-process approach that causes this specific functionality to not be possible? I think the poster means that you can't loadbalance with an apache between multiple tomcat instance, a clustering / fail-over technique for low cost sites (say 2 or 3 webservers). In any case, if clustering features don't work then it's definitely no surprise that any web application that needs to scale wouldn't use this approach...unless it is being used in some way by such web applications in production - anybody know? Any web application that needs to scale wouldn't use httpd (or anything else) in front of tomcat, so the question in- or out-process tomcat doesn't matter. From 5 high performance application I know the details of, 1 is still using apache in front; more out of habbit, rather than by need. Others are using a hw loadbalancer in front of x tomcat servers, and some servers for static content (which can be apache httpd, but is mostly something different) which are parallel to the tomcat servers. So the loadbalancer decides which server to ask for specific content type. regards Leon -- View this message in context: http://www.nabble.com/In-Process-Tomcat-tf3972772.html#a11281236 Sent from the Tomcat - User mailing list archive at Nabble.com. - 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]

Hi, Is there any plan in Tomcat's roadmap that when Tomcat will support JSR-196? Thanks
Programmatically stop/start context (webapp)
Hello, I would like to be able to start and stop my 'cache' webapp from my own 'cache-admin' webapp. These two apps usually run on the same Tomcat instance, but not always. I am not sure if I should use ManagerServlet or HTMLManagerServlet, or Embedded tomcat. I have found some examples on this newsgroup and onjava.com but was unable to get them to work. Any ideas? I would also like to somehow (Ajax perhaps) grab the contents of the log file and display it, updating every 2-3 seconds, in my 'cache-admin' webapp when the 'cache' webapp is started/stopped. I am using log4j for logging. Many thanks for any help!

Performance
Hi All
I have developed a web site that opens a recordset at start, and while
looping through records of the main ResultSet i Open a new ResultSet for
each record, to get a specific information, then close it. like this:
while( rs.next() ) {
Statement stmt = dbConn.createStatement();
ResultSet newRs = stmt.executeQuery(SOME QUERY);
..
.
*Some Code Here*
.
.
stmt.close();
newRs.close();
}
I feel that this way is resource-consuming, is it or not, and if it is, what
is the best way to code this code??
Thanks
Re: Performance
1. This is a question for the
http://forum.java.sun.com/forum.jspa?forumID=31 java forum , not Tomcat.
2. Yes, it's an incredibly wasteful way of doing things. Change your sql so
the 'extra info' you need is included in the same query. Chances are if you
can do it with two queries you can do it with one.

Change your web.xml, both in tomcat/conf and myApp/WEB-INF to 120. Get rid of session.setMaxInactiveInterval(120). The setMaxInactiveInterval() method of javax.servlet.http.Interface HttpSession takes the timeout in SECONDS, not minutes. So you are setting your session timeout to 2 minutes.

Consequently, placing httpd in front of Tomcat just to serve static content does not improve response time for those requests, and has a significant negative impact for dynamic requests due to the added path length. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

I don't want to open this can of worms again, I think there were about 1000 discussions in the past, you should check the archives if you want the details. Basically the anti-httpd fraction (which i belong to) states: thats usage of httpd is a) less secure than usage of tomcat alone (at least it doesn't add any security cause requests are passed along, and the last security issue was in the c code of mod_jk - httpd). b) less performant, since you add another node which does nothing but consumes time. How would hardware load balancers go about handling sticky sessions? Or would you have to design for a stateless web tier so that any Tomcat instance will do upon the next request? HW loadbalancers can handle sticky sessions far better than apache. You can stick it on cookies, path elements, source ip-adresses, page content, load, colour of users hair On the minus side they start at 10K USD and you usually need 2 of them.

Re: Programmatically stop/start context (webapp)
Syg, interesting question I think, that what would make it tricky, is the actually packaging of the solution. In theory if you do this (I'm writing this blind, excuse the code) import org.apache.catalina.ant.*; StartTask startTask = new StartTask(); startTask.setUsername(admin); startTask.setPassword(); startTask.setUrl(http://localhost:8080/manager;); startTask.setPath(/ContextOfWebApp); startTask.execute(); This is actually turned into a URLrequest and sent to the manager... so in theory if you want to you can just simulate the GET with the required params and http hdrs. and a similar thing for stopping it. Ok, but heres the tricky bit and if you can figure out how to do it in your dev environment, no problem. The required jars are in the server main package so they will be missing from your servlet. To develop you can just drop them in BUT then somehow when you actually package it, you have to take them out. So... you will probably have to use late binding ie Class.forname or something, so you can get it working in dev environment and omit the jars in deployment.

Multiple instances vs multiple hosts
In production, for organizations that run multiple web applications, would they run it on different instances of Tomcat (1 instance per web application or group of related web applications), or all web applications as different hosts on one instance of Tomcat? (Not taking into account clustering, where everything in whatever setup is chosen would be duplicated.) What are the tradeoffs in terms of performance, resource usage, maintainability, etc, and what are your comments based on past experience? What's common in production and what isn't as much?

securing directory
Hi all, I would like to know if anybody can tell me how to restrict web access to my web app's base directory and its sub directories. i.e. webapp Test1 has a file root.xml (tomcat\webapps\Test1\root.xml) While I do need read access programmatically, I need for web users to not access that file. I am using an isapi connector through IIS (if that helps). I do realize that permissions for directories reside in catalina.policy but that appears to be permissions for programmatic access (i.e. my webapp). I am running Tomcat version 5.x. Thank you for your help.

System.setOut(new YourCustomPrintBuffer(System.out,this)); Remember you have to pass it back to the base (super) class, or else it wont end up in normal logs.

Re: Programmatically stop/start context (webapp)
Yes, these are the ones I am following. Specifically the Tomcat 6 how-to. The
parts I don't understand are:
1. What the 'tomcat compat package' is. I downloaded MX4J but only copied the
mx4j-tools.jar to /tomcat/lib. But in step 1 it says Install the tomcat compat
package. I am hoping not to have to install anything, as I don't want to use
MC4J, I just want to use MX4J's Java classes, correct? In other words, I want
to connect to the MBean server myself, programmatically, so I shouldn't have to
install the MC4J app ...
2. This little tidbit is a keeper - With ${AJP.PORT}=0 no ajp connection where
started. I have no idea what this means. I know that I already have an AJP 1.3
connector set up at port 8009. Anyway, I tried cut-and-pasting the Connector
... section and now my Tomcat doesn't start, no errors. I tried using port 0
... maybe that's the problem.
3. It says to add all the parameters to the CATALINA_OPTS. In other places it
says to add them to JAVA_OPTS. I guess CATALINA_OPTS is correct.
At any rate, when I get all this worked out the idea is to connect to the
Tomcat MBean server, query and change its Server / Service / Engine / Host /
Context MBean. The first step is getting Tomcat to start with these options
set though!!
I'll keep you all posted, thanks for the tips.
Bob

We prefer the one-Tomcat-instance-per-webapp because we want to insulate them from each other. If one application leaks memory (for instance), then only one JVM will be disabled when that happens. Our current needs are limited, so we can run all our applications on a single physical machine. Moving to multiple machines would be trivial since the applications are already deployed separately. To deploy in this way, with everything running over port 80 (and 443), we need to front these Tomcat instances with a routing web server (we chose Apache httpd). What are the tradeoffs in terms of performance, resource usage, maintainability, etc, and what are your comments based on past experience? What's common in production and what isn't as much? Memory usage is certainly the most significant resource waste when considering the above strategy. All of our applications fit comfortably in a quarter gigabyte or so, so running multiple JVMs on the same hardware isn't a big deal for us. I would venture a guess that in terms of CPU performance, the difference is negligible, depending on how your operating system treats threads versus processes. We are deployed on Linux 2.6 which treats them about the same, so I would expect the performance impact to be minimal. I find this setup to be very maintainable, since sometimes Tomcat versions and built-in libraries interfere with each other. In the described setup, each application has its own Tomcat environment that can be separately tested, upgraded, etc. If you need a new XML parser but Tomcat's built-in version is interfering (used to happen... might not after the 4.1 versions), no problem: replace the built-in XML parser, test, deploy. No need to interfere with other applications. In other production environments, I have typically seen large applications clustered. One machine runs one application, and that machine is duplicated for other members in the cluster. Depending on your hardware, more applications per physical server might make more sense. These days, you can get some pretty beefy commodity 64-bit hardware that can handle a lot of traffic.

tomcat performance dilemma
Hi everybody, I am facing a stress-testing problem using Tomcat 5.5 and Axis 1.4, and I really need some ideas about what is happening behind the scenes. This is the configuration: a few web services hosted on Axis 1.4 are deployed on Tomcat. Everything runs on 2 Linux Pentium 4 machines (with hyperthreading), one as client using Jmeter, the other one as server. The problem is that I cannot run as many / time-consuming requests so that the processor on the server reaches 100% CPU load. It only reaches 90%, so the measurements for throughput that I need to obtain by this testing, cannot be too relevant; I want 100% of the CPU working. So my question would be - why is 10% of the CPU idle ? I should mention that I already did a few performance tweaks, for the JVM memory, and decreased the connection timeout for Tomcat to a few dozen milliseconds. Still, it doesn;t reach 100% load, although I varied request message length, and thread numbers. If you have any ideas, please help.

What static servers have you generally seen in use apart from HTTPD - are there things that just work better in the setup you described than others? http://lighttpd.net/ Without using hardware load balancers, how could you implement the architecture whereby (as you described) lighttpd serves static content, Tomcat serves dynamic content, but with the two sets of servers (lighttpd and Tomcat) in parallel rather than lighttpd fronting Tomcat? Would you be required to, in your JSPs, include all links to static content using http://staticserver.site.com/...? That would be one very good option. I think ebay uses it and many others. Another option would be for example puting a squid infront of the tomcat and let it cache the static tomcat served by tomcat (and any other cacheable content). Its almost the same as apache httpd infront, but squid is faster in a number of things. However, I think there are a lot of possible solutons, without knowing your usecase its hard to pick one :-) regards Leon What are all the available options to implement this setup?

tomcat 6 - invoker servlet?
hi, I realized that, on tomcat 6.0.13, the invoker servlet /servlet/ doesn't work. To make it work I had to add in the file /tomcat60/conf/context.xml the parameter privileged=true The contents of this file will be loaded for each web application Context reloadable=false privileged=true Is there any security issue in tomcat 6.0.13? Can I use privileged=true without having security break? thx Leonardo
Use JMX to manage applications
How, from a web application deployed to Tomcat, can you customize the behavior of your web application based on attributes specified in an MBean? The link http://tomcat.apache.org/tomcat-6.0-doc/monitoring.html talks a lot about Ant tasks, but that's not really what I'm looking to do. How can you get programmatic access to MBeans? And how do you deploy MBeans to Tomcat? I'm pretty confused here...hopefully someone can clarify.

Is HttpSession id a GUID
Hello, is the http session id a global unique id within a tomcat 6.0.13 cluster?

Can't override Context className from context.xml located in webapp/META-INF dir
Hi, I am running Tomcat 6.0.13 and when i specify the className attribute in a Context element inside a context.xml file inside the META-INF directory of my webapp, it is ignored. If i move the context.xml file to conf/[Engine]/[Host]/webapp.xml it works. Any ideas? Is this a feature, a bug? I can't find any documentation that specifies limitations on the attributes of a Context element depending on where it is located. Appreciate any thoughts.

Nathan,
Here's a size 8 foot... ;-)
Yep: already seen that link which reports a [730048] error, which is close

Only have a single instance running (not as a service for now - but via

everything works fine using a WAR that has been running on Tomcat 5.0 for
two years-ish.

Date: Mon, 25 Jun 2007 21:55:10 +0100
Have spent the last 8 hours trying to work out how to use the 'native'
library for Tomcat 5.5.23 - without any success.
Have managed to download lots of C++ source code - which is useless since I
don't have an MS C++ compiler and don't want to buy one as I live in a Java
world not a C++ world !!!
Further digging revealed binaries for 'tcnative-1.dll' and 'openssl.exe'
but having put these onto my PATH then I no longer get the warning re not
using the native stuff but instead I get:-
SEVERE: Error initializing endpoint
java.lang.Exception: Socket bind failed: [730047] An address incompatible
with the requested protocol was used.

Apologies if the answer is 'obvious' but have searched FAQs etc etc to no

why is it so bloomin hard to find a download for it that is deployable !!

RE: Windows Native lib
Due to the ascii sorted list on a volume then the last entry in http://tomcat.heanet.ie/native/ is actually Version 1.1.9 - and so this is the version I actually have tried, not 1.1.10.

Re: securing directory
If you really really want to it: Read about exclusion rules in http://tomcat.apache.org/connectors-doc/reference/uriworkermap.html but think twice, if this is robust, i.e. if the web server admin will have a chance to keep this up-to-date.

Dynamic form-login-page?
I'm having problems using FORM authentication and a dynamic login page via Struts 2. I've tried the following web.xml/struts.xml entries with S2.0.8 Tomcat 5.5.23, but get a 404 The requested resource (/mywebapp/login.action) is not available message. login-config auth-methodFORM/auth-method form-login-config form-login-page/login.action/form-login-page form-error-page/loginFailure.action/form-error-page /form-login-config /login-config action name=login result/login.jsp/result /action The login action loads the login.jsp just fine when called directly, but doesn't work when invoked by the servlet container. Instead I see the following in the Tomcat log: Jun-25-2007 10:31:30:865 AM, PDT [DEBUG] (org.apache.catalina.authenticator.FormAuthenticator) - Save request in session '930B154E1AD9BFB1283165CD888441EF' Jun-25-2007 10:31:33:053 AM, PDT [DEBUG] (org.apache.catalina.core.ApplicationDispatcher) - servletPath=/login.action, pathInfo=null, queryString=null, name=null Jun-25-2007 10:31:33:053 AM, PDT [DEBUG] (org.apache.catalina.core.ApplicationDispatcher) - Path Based Forward Jun-25-2007 10:31:33:053 AM, PDT [DEBUG] (org.apache.catalina.core.ApplicationDispatcher) - Disabling the response for futher output I've asked on the Struts2 list if this should be possible to do and the response I got was it definitely should work. I'm wondering if there's a special Tomcat configuration (beyond my webapp's web.xml struts2 filter mapping) I need to add to enable a .action extension being used for form-authentication.

no-cache Headers In Authenticated Zones
Hi all, It seems that Tomcat automatically adds Pragma: no-cache and a pre- dated Expires header whenever the user requests a page that requires container-based authentication. This has come up on the mailing list in the past: http://mail-archives.apache.org/mod_mbox/tomcat-users/200504.mbox/% [EMAIL PROTECTED] the solution given however is for a form-based login and we're using basic authentication and I've been unable to adapt the solution to work for us. I'd like to stop Tomcat from adding any caching directives and handle it manually in my webapp. I can setup a filter to modify the response headers, but I can't find a way to remove those headers - only to modify their values which doesn't seem to be enough to get browsers to cache the content. We're running Tomcat 5.5. Any help would be greatly appreciated.

How to add -Djava.library.path to tomcat
Hi, I would like to load a library (.dll in windows and .so in linux) in a Java application, so I have to add the path of the library to LD_LIBRARY_PATH (Linux) or PATH (Windows). In addition, I also need to add -Djava.library.path=. However this is only for a standalone java application. But I'd like to deploy these applications as Axis web services, so how can I do the similar thing in Tomcat? i.e. how can I add -Djava.library.path in tomcat (in both Windows and Linux). Thanks Eric
RE: Windows Native lib
Lakshmi, Thanks for the reply. If what you say is true then this 'feature' of Tomcat is obviously beyond the understanding of us 'mere mortals'. I have an application to maintain without having to get to grips with the detailed ins-and-outs of the guts of each Web/App/EJB server, etc, that I'm runing on. What an 'ipv4' is, and how it compares to an 'ipv6', is quite frankly too dull to explore. I had just assumed that there was a dll that replaced parts of the java Tomcat runtime and hence ran faster. Either it was loaded and 'stuff' ran faster, or it wasn't and 'stuff' went more slowly. Call me naive. Why have they released version 1.1.10 if it 'just does not work'? I don't think that I'm trying to do anything weird - I'm just trying to deploy a WAR file. So if you, or anyone else, can advise the exact details of how to make this 'plug-in' actually 'plug in' then great. Sorry - this isn't a rant - and its not aimed at anyone. But how do you install the native stuff on 5.5.23 for Windows - surely someone has done it! Some simple instructions from someone please!

What an 'ipv4' is, and how it compares to an 'ipv6', is quite frankly too dull to explore. I had just assumed that there was a dll that replaced parts of the java Tomcat runtime and hence ran faster. Either it was loaded and 'stuff' ran faster, or it wasn't and 'stuff' went more slowly. Call me naive. Why have they released version 1.1.10 if it 'just does not work'? I don't think that I'm trying to do anything weird - I'm just trying to deploy a WAR file. So if you, or anyone else, can advise the exact details of how to make this 'plug-in' actually 'plug in' then great. Sorry - this isn't a rant - and its not aimed at anyone.

Re: Use JMX to manage applications
Hi LightBulb, If you asking this, because of Robert Bowen question Programmatically stop/start context from WebApp, I also wait with anticipation for the JMX solution. I have a feeling that making a light weight JMX client that lives in a servlet, may not be that easy, we'll see what he comes up with. Its very quiet, so I'll volunteer an explanation, and get shot down in flames ;) but it gets the conversation going , normal procedure ;) You got this Servlet Management Interface to Tomcat and it calls into its OWN engine, and does stuff (like deploy start/stop) as well as provide other servlets like a JMX Proxy, that grab that JMX call, feeds in down to the MBean Server, and returns the XML to whatever made the call. BUT, there is another important management interface, that is not really talked about much, and its very to use and very powerful, and thats what you seeing in that article. http://tomcat.apache.org/tomcat-6.0-doc/monitoring.html If you start to think about how an IDE works its magic, and starts and stops, and deploys and undeploys you may at first think its talking to the manager servlets directly its not. In Tomcat there is another client Task engine, which acts as a client to the manager servlet. Netbeans in fact uses that, through ant. So in fact what is happening, is it calls into the CLIENT TASKS, they call the Manager Servlets (which can be located on any machine), and the job gets done. So for example if Robert Bowen emulated the management servlet, in his own servlet, he will ONLY be able to control the tomcat his servlet is in, and will end up also having to make these CLIENT TASKS. Now because I think its not that easy to make JMX clients, one of these CLIENT TASKS, is in fact a JMX client. So you or and IDE via ant, calls the JMX CLIENT TASK, the client task then does the JMX stuff for you and calls the SERVLET MANAGER... it does its thing, returns the REMOTE tomcat answer to the LOCAL tomcat, and the ant script gives it back to you. Now if you look at the little bit of code I gave Robert to start a server all I'm actually doing is bypassing ant, and calling the ant task directly, because who wants to use ant from a web-app, and note that I'm hitting the CLIENT TASKS, and that means it can control any server on any machine, not just my own. The guys rekon its kludgy, and they right because calling into Tomcat has versioning issues, but I think its pretty safe, because if they changed that interface, IDE control of tomcat would break... Netbeans wouldnt work with Tomcat. How did I get onto this just by looking at the ant script NB generates for tomcat. This interface you looking at, I think is more geared towards IDE control, than pure JMX, else I think there would be more emphasis on the client side, there isnt, because its in tomcat already. hope that helps - Original Message - From: lightbulb432 [EMAIL PROTECTED] To: users@tomcat.apache.org Sent: Monday, June 25, 2007 9:04 PM Subject: Use JMX to manage applications How, from a web application deployed to Tomcat, can you customize the behavior of your web application based on attributes specified in an MBean?

RE: Windows Native lib
Okay, I am glad that 1.1.7-ipv4 is working. 1.1.9 would have worked with the address=0.0.0.0 attribute since it is the IPv6 version. A README file in http://tomcat.heanet.ie/native/ would have been helpful. IPv4 is the 32 bit IP address of a device(computer, router etc.), for example 192.1.1.1. Since the world is running out of IPv4 addresses, IPv6 is the new standard with 128 bit address space. http://www.ipv6.org/ From your mail, it seems you are on IPv4, so you don't have to worry about IPv6. Yes, the Tomcat folks could have done a little more on APR documentation. I spent a few days unravelling everything on all 3 OS - Windows, Solaris, Linux. Everything had to work in my organization - HTTPS and HTTP transport over both IPv4 and IPv6 on all the 3 OS. So I documented my experience in the posting Tomcat 5.5, APR, IPv6, HTTP and HTTPS. I was hoping either Mark Thomas or Mladen Turk would comment on my post, update some document or delve into why 1.1.10 gives the errors that are not present when any of the earlier versions were used. But there was no discussion on this thread and I have moved on with my working combination.

Re: Dynamic form-login-page?
To add some more context to this, I was able to successfully use a Struts 1.x action in my web.xml. Struts 1 was based on a servlet vs the ServletFilter that Struts 2.x is based on. Is there anything about this architectural change that would require a different Tomcat configuration? The default extension for struts also changed from .do to .action. Is there anything about this that requires a special Tomcat configuration for form-login-pages that are handled by Struts2? Any help or working examples of a S2 app deployed on Tomcat 5.5.x or 6.x is greatly appreciated! - Original Message From: Jon Wilmoth [EMAIL PROTECTED] To: users@tomcat.apache.org Sent: Monday, June 25, 2007 2:43:45 PM Subject: Dynamic form-login-page?

Re: Use JMX to manage applications
Hi Again LightBulb, In this good article http://www.javaworld.com/javaworld/jw-08-2005/jw-0801-jmx.html You will find an example JMX client, in SRC for talking directly to Tomcats JMXProxy One thing I dont see in the JMX interface, maybe it is there, is a way to start stop webapp through JMX. Just want to say, this thread made me have a good look at JMX in Tomcat, an area I never bothered with before well done!... although I think making JMX clients is too much hassle, looking at Tomcat through a professional JMX client like JConsole is pure magic. You know if there was just a screen shot of Tomcat in the JConsole on the site, I think it would make people (like me) immediately see what a magic facility this is. The other thought I had was that I think if TC scrapped the logging tools it has now, in favour of an XML format, and a standard viewer, or any other format one wanted if they set up a bit of XSL, I think logs would look damn good in JConsole as well, would be easy to server through JMX, or just in a web page. The current scheme seems to make them to hard to get at, which is actually a bit weird considering the things are sitting in a web server IMHO Have fun - Original Message - From: lightbulb432 [EMAIL PROTECTED] To: users@tomcat.apache.org Sent: Monday, June 25, 2007 9:04 PM Subject: Use JMX to manage applications How, from a web application deployed to Tomcat, can you customize the behavior of your web application based on attributes specified in an MBean?
