Auto Session Creation and memory usage
Hi Guys, I am working on creating some more scalable tomcat applications. I have addedd a SessionListener and it seems that hitting a jsp page triggers a session to be created. If there are 1000 users and only 10 are signed in, I dont think 1000 sessions need to be created yes. How do I turn off auto session creation, or is this impossible. (Google has not been my friend in this regard, do people not think about this sort of thing?) -jacob - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Tomcat/Mod_jk on Redhat
Hi Guys, We are trying to introduce Java technology in our workplace (all the staff have been recently re-trained in Java). As far as I can tell, our System Administrators are really only resourced to be able to install standard Redhat packages. I initially thought we could install a clean vanilla tomcat, and then install mod_jk or mod_proxy_jk, however I am told by our System Administrators there are no packages for mod_jk, or mod_proxy_jk (I think they mean, that there are no packages that are supported by Redhat). I wonder if one of you more experienced people may be able to recommend a Redhat package or set of packages that we can ask our System Administrators to install? (That you guys are using in production of course).

Tomcat Filter Ordering
Hi, I am trying to separate all work from within one large filter, into two smaller filters. One filter for handling authentication/authorisation and another to handle url redirecting.

Re: servlet init error pages

Do you have an apache front end? If this is true you must configure the error page from within your httpd file. I usually do something like this in my apache virtual host: JkMount /* ajp13_worker JkUnMount /error/* ajp13_worker ErrorDocument 503 /error/TomcatMissing.html Note, this error occurs when tomcat is down, so the error page can not be returned by tomcat! So this configuration says, display the error page from an apache httpd directory instead of trying to display it from tomcat. Hope that helps!

Re: Help with Tomcat IIS

Resource vs Resource-ref
Hi, I am having trouble with something google and the docs cant seem to help. 1) After setting up a connection to a database in the context.xml file using the Resource tag, do you need the resource-ref in the web.xml file. I have tried with and without and it doesn't seem to make a difference. 2) I want to be able to deploy two instances of an application on the same installation of tomcat. (using two separate virtual hosts) with two separate databases. If I simply deploy the application twice, with two different context.xml files, sometimes this works (ie one instance uses the database from one context.xml and the other instance uses the database from the other context.xml) but sometimes it seems they both use the same database!! How do I fix this? The tomcat documentation seems to imply the context.xml file jndi information is local to a single applications context. It appears this is not true if that is what the documentation means.

John It would be better to alter the application (if you can) to not include private information inside url's. But either way, just make the logs read writeable only by tomcat. That way the user has to have access to tomcat before they can read the logs. And if the user has access to tomcat, then they will be able to read your logs no matter wether your logs are encrypted or not. (ie if the user has access to tomcat they can simply monitor all incoming traffic via other means, and get much more confidential information than just urls and ip addresses) Best Regards, Jacob - 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: Changing tomcat version
Hi, I am by no means an expert, however generally I too have had problems running the latest versions of tomcat using Java 1.6.0. I am not sure of the reason but using Java 1.6.0_02 makes most problems go away. (I am guessing the tomcat 6 distro is compiled with java 1.6?) Try this to get a working tomcat 1.6.0 (unix only) - Make an empty directory (i do adduser appserver) - Download and install java 1.6.0 into it - Download and isntall tomcat 6 into it - Edit catalina.sh to force it to use java 1.6.0. - Copy your web apps over. This usually takes me all of 5 minutes on a linux box, and gets me a stable working version of tomcat every time. (Which we have running production). When it comes time to upgrade I just repeat above steps with newer versions in a new directory. The beauty if this is that if there is a problem you can always go back. And not only this but I find that ubuntu and some other distros make some strange changes that cause me problems. (ie, like Ubuntu's predilections to not use Suns Java. I agree with the philosophy, but in reality causes much grief). Best Regards, Jacob Deepa Paranjpe wrote: Hi all, I was using tomcat's version of 4.1 for a long time and it was working fine.

Re: What is Tomcat 6 status?
It is not as simple as Michael implies, It is my understanding that tomcat 6 makes many improvements over tomcat 5. If this is correct then it makes choosing between 5 and 6 more complicated than you suggest. (And to someone who does not know what the JSP/servlet specs are, this is even more unclear). My guess at the best answer is to use 6 even if you dont need all of the features of 6, as 5 is bound to become unsupported long before 6.

At tomcat.apache.org, you see that under production quality releases, version 6.0.13 is listed as well as 5.5.23.

So I guess I am asking how do you actually get a stack/heap dump of some sort out of tomcat? I am new to this sort of thing and Google doesn't tell me much except use some fancy gui tool.

Tomcat 6 Manager App question (Memory usage)
Hi, The manager application status page reports the following regarding memory usage: Free memory: 0.86 MB Total memory: 9.35 MB Max memory: 63.56 MB I am confused about what this means. What is the difference between total memory and max memory. Is the free memory what is left of total memory, or maximum memory?

Re: UserDatabase security
As far as I am aware you cannot resolve this problem except by switching
to LDAP for your authentication. (Although I would be happy to be
corrected!)
For any larger scale hosting, LDAP provides a more secure solution.
(However it does add an extra point of failure). Any hosting solution
where users share the same instance of tomcat is dubious because anyone
can read anyones files!
Which gets me thinking, what is to stop anyone writing an application
that simply deletes the tomcat installation?

Hi,
I have a question regarding Tomcat server UserDatabase
on Linux.
When choosing a MemoryUserDatabase, tomcat users and
passwords are declared in a tomcat-users.xml file. The
tomcat user running the server must have read
permission on this file.
At the same time, all webapps running in tomcat are
running under the same Linux user ('tomcat'). So any
webapp can access this file and display its content.
My app is hosted on a shared Linux server. With the
present configuration, I can retrieve this file and
display every user login/password, then if I wanted
to, I could go into somebody else' webapp manager and
undeploy it.
I am a bit worried that somebody would do that to
me...
Is there a way to ensure that only the root user can
read this file ?

In this case, which user would be authenticated in LDAP ? If th user connecting to LDAP is 'tomcat', the issue remains no ? Not quite. You reconfigure tomcat to use LDAP to lookup passwords, instead of reading a text file. LDAP is a server that listens on a port on a server. So the passwords are no longer stored and owned by the tomcat user, but by the LDAP server, which can have its own file permissions and so on. Make sense? Lookup Tomcat LDAP in google.

I think this would be cleaner than a cgi-bin-Tomcat hack. What is your environment? Perhaps we can come up with a better solution. Its a system where we have no permission on any files except user home directories and the cgi-bin directory. So we can run tomcat as a non-unprivileged user on a high port, but we need the ability to allow files to be served through the apache web server on port 80. So it has to be something we can install in the cgi-bin directory. In the past we have had a perl script to simply make a connection to an app server and pass the data through.

Re: How to set global variable in Tomcat 5.5.17
Instead of attaching information to a session context you can attach information to an application context, whats more, instead of loading the config each time a session is created, you can create what is called a Lifecycle listener which will load the configuraiton file once, when the application is loaded into the web server! Look up lifecycle listener in google. I can send sample code if you need it.

In my web application, when a user session created, I call these Java classes to parse these configuration files and save the linked lists into the session. So, every user sessions contain the same set of linked list and, as a result, it reads these files every time when session created (so many I/O access, if many session created as the same time, it will slow down the server). Now, I want to save these linked lists as a global variables in Tomcat so that each JSP and Servlet can access these global variables and reduce I/O access and memory usage.

Re: Session timeout during method execution
Christopher Schultz wrote: This was already pointed out (by me, in fact). Sometimes, you can trick the browser into keeping the connection open by sending data back little by little. For instance, I think you might be able to keep the connection open by sending HTML comments like !-- still processing request -- every so often. I've never tried it, but it might work. This does work, but there is a limit to how long you can keep the connection open. I have a report which outputs a line in the html table every 5 seconds, from the users perspective it seems more responsive because they start seeing things straight away, but after about 30 seconds the browser closes the connection. (I don't know the exact times but IE keeps the connection open shorter than firefox). The best strategy for long-running requests is to have the background-processing occur in a separate thread and have the user's browser make regular requests to see if processing is complete. This solves the session timeout problem (just have the browser re-request the update page every 60 seconds or so and the session won't time out) and the browser timeout problem (since you aren't waiting for 10 minutes for data to come back).

Re: timestamp of tomcat startup?
I am no expert, but I thought there was a thing called a LifecycleListener where server.xml can be configured to call some java code upon startup of tomcat, this would do what you want yes?

The message is logged by org/apache/catalina/startup/Catalina.java, but it does not appear to save the time value anywhere. I suppose you could scan the log, looking for that particular message, but that's not exactly an elegant solution. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Deploying to / using context.xml
Hi Guys, I am a bit stuck with something. When I deploy my web app in netbeans 5.5 it puts my app under / (instead of /Appname/) after changing the context.xml When I deploy using the tomcat manager manually to the production site, it goes under /Appname/, why would this be? My context.xml file is: ?xml version=1.0 encoding=UTF-8? Context path=// I have tried with path= and path=/, what am i doing wrong? They are both tomcat 5.5.x Thanks!

Re: timestamp of tomcat startup?
I think either a LifecycleListener or ServletContextListener is what you want, you can detect tomcat startup/shutdown and/or application startup/shutdown http://tomcat.apache.org/tomcat-5.5-doc/catalina/docs/api/org/apache/catalina/LifecycleListener.html Let's write a simple application lifecycle event listener that writes a message to the console of the server when the web application is ready to accept requests and when it is going to be removed. Listing 1 shows the code for a simple application event listener class. http://www.onjava.com/pub/a/onjava/2001/04/12/listeners.html?page=2 cifroes wrote: cifroes wrote: Hi, catalina.out hast the time Tomcat took to startup but I need to know the timestamp [date of when tomcat started] of when tomcat is ready to receive requests. Let me clarify a bit: I need this timestamp to measure downtime of a server, I don't need exactly precision to the ms but at most 0.5second error margin. And the timestamp should be made when tomcat server is ready to receive requests or at least 0.5second error margin between when Tomcat is accepting requests and that timestamp. I hope it's clear now :) Thanks for all the help already, --cifroes - 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: Deploying to / using context.xml
Thanks, let me change my question then (: Given a Host entry with a directory /usr/local/tomcat/webapps3, and the /usr/local/tomcat/conf/Catalina/hostname/manager.xml in place. How do I easily deploy/redeploy war files for the root directory?

They are both tomcat 5.5.x Unless your Context element is in server.xml (strongly discouraged), there should not be a path attribute at all. Tomcat determines the URL path to the app based on the directory (or war file) name of the app if it's under appBase, or the name of the .xml file if that's placed in conf/Catalina/[host]. Look at the doc for the path attribute of Context: http://tomcat.apache.org/tomcat-5.5-doc/config/context.html The value of this field must not be set except when statically defining a Context in server.xml, as it will be infered [sic] from the filenames used for either the .xml context file or the docBase. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Deploying to / using context.xml
Thanks! That makes it all clear (: So it means if you have 5 hosts you need to have 5 applications in netbeans all called ROOT (: Caldarale, Charles R wrote: From: Jacob Rhoden [mailto:[EMAIL PROTECTED] Subject: Re: Deploying to / using context.xml Thanks, let me change my question then (: Given a Host entry with a directory /usr/local/tomcat/webapps3, and the /usr/local/tomcat/conf/Catalina/hostname/manager.xml in place. How do I easily deploy/redeploy war files for the root directory? If by root directory you mean the default app for the Host, it must be named ROOT (case sensitive). If you want it under webapps3, the app should go in either the webapps3/ROOT subdirectory, or webapps3/ROOT.war. If your app is deployed outside of the appBase, then place a ROOT.xml file in conf/Catalina/hostname containing a Context element with the appropriate docBase attribute, and delete any ROOT directory under webapps3. If you really, really want to call your default app something other than ROOT, the simplest solution is to have a dummy app in ROOT that does nothing but redirect or forward to the desired default. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Problem setting server.xml host context field.
Hi Guys, I am new to all this so it could be a stupid question. In my server.xml I have setup a second host entry, to enable mapping of a particuar application to a virtual host in apache (via mod_jk2). The following seems to work ok, except or a possible bug: Host name=fish.org appBase=webapps unpackWARs=true Logger className=org.apache.catalina.logger.FileLogger directory=logs prefix=virtual_log. suffix=.txt timestamp=true/ Context path= docBase=/usr/local/tomcat/webapps/FishApp debug=0 reloadable=true/ /Host The docbase is set to the path to the application i wish to see in my virtual host container. This works when i startup tomcat. However if i undeploy/redeploy the application within the tomcat manager, it no longer works. Its as if the Host entry stops working or disapears when you undeploy, never to return again. Has anyone had this problem? How do you fix it?

Re: Problem setting server.xml host context field.
Thanks for your reply! I was not aware that mod_jk2 was not the best one to use (I assumed 2=apache2). Rather than fixing my mess, how about I ask a different question! I am using the latest version of tomcat, I would like to have a single version of tomcat running on one port, which I can deploy multiple applications. I would like to use virtual hosts so that: mainserver.com:8080/Application1/index.jsp maps to fish.com/index.jsp mainserver.com:8080/Application2/index.jsp maps to apples.com/index.jsp Ignoring the mess i have made, how would i do this? Any help or pointers to documents that might help would be much appreciated!

I have setup a second host entry, to enable mapping of a particuar application to a virtual host in apache (via mod_jk2). You do know that mod_jk2 has been deprecated for almost two years? Pretty much all the useful stuff has been implemented in mod_jk in the interim. The following seems to work ok, except or a possible bug: Host name=fish.org appBase=webapps unpackWARs=true Logger className=org.apache.catalina.logger.FileLogger directory=logs prefix=virtual_log. suffix=.txt timestamp=true/ Context path= docBase=/usr/local/tomcat/webapps/FishApp debug=0 reloadable=true/ /Host You probably don't want the two Host entries to use the same appBase, unless you really want the apps deployed in both of them at the same time. You don't say what level of Tomcat you're using, but with current versions (5.0 and beyond), the above will get the app deployed twice under fish.org, once as the default, once as FishApp. The doc for current levels also recommends quite strongly against putting Context elements inside server.xml. However if i undeploy/redeploy the application within the tomcat manager, it no longer works. You need to have a separate manager app for each Host. In current levels, this would be accomplished by putting a manager.xml file in conf/Catalina/fish.org as well as the usual conf/Catalina/localhost. However, unless the overlap of the deployment directories of the two Hosts is straightened out, I suspect it will never work reliably. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

Re: Problem setting server.xml host context field.
I would like to use virtual hosts so that: mainserver.com:8080/Application1/index.jsp maps to fish.com/index.jsp mainserver.com:8080/Application2/index.jsp maps to apple.com/index.jsp Thanks for your patience, I have one final question I think, Based on previous posts, I have created inside Engine two Host containers for both apple.com and fish.com with paths: /usr/local/webapps /usr/local/webapps2 Each domain is now successfully serving its own apps in the equivalent directory and each app has its own META-INF/Context.xml My question now however is, the manager to manage deployment of war files seems only to work for the first Host container with directory /usr/local/webapps. How do I make it work for both? Do I have to load two copies of the manager somehow? (I dont have much memory on this machine) ie http://fish.com/manager/html/ works but not http://apple.com/manager/html Thanks, Jacob - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
