Re: Antigen found VBS/SST virus
It's a Windows/Outlook virus, they run the attachments in some cases without you opening the file or anything. I got the same email, but since I don't use Windows or Outlook, it has not gone on to anybody else in my company. (I will avoid a flame fest here with making jokes about MS products :)) Supposedly this virus does no damage - it's just annoying. http://dailynews.yahoo.com/h/nm/20010212/wr/tech_virus_dc_1.html The main concern to me is why the list notices it's a virus and then retransmits it as an attachment on the notification! Seems like a pretty bad idea. Any way to stop the SMTP server from doing that? Anthony Ikeda wrote: > > Whats the story with this? Has anyone else had this distributed through > their company?

Re: Servlet as welcome page?
If you want to have a servlet handle just the initial page, just map the servlet to index.html. One thing is that you might have to actually have an index.html file - it can be empty - to trick Tomcat into serving it up.

I'm sure that will work as long as you don't miss any. :) Generally the idea is to have a 'root jail' or sandbox. The idea is that the server (tomcat) will be able to read and possibly write anything in it's sandbox, but not read or write(especially not write) anything outside of that. This will minimize a security exploit to being able to trash the sandbox in most cases and not effect the rest of the system. To truly implement this, native code would need to be called because these are OS level calls, but you can get a rough approximation with privleges. > On a side note, I found that I was regenerating the > Windows registry settings for redirecting IIS every > time I started up Tomcat. > > > This doesn't have to be 'nobody' though.

That's probably a pretty good idea. This would allow you to limit the ability of apache to read the 'raw' files that are intended to be served by tomcat so that people couldn't snoop at your stuff (if you care about that). > > And if you want it to be owned by root, that's fine, > > just use the group permissions to set the write > > access. > > Do you mean something like: > > 1 -r--rw-r-- 1 root nobody 1024 foo That's fine, but giving root write access won't hurt anything (if someone has root privs, they can change the write privs anyway). -- --- Geoff Lane <[EMAIL PROTECTED]> - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Re: Running Tomcat as non-root
/usr/local/tomcat doesn't necessarily have to be owned by root. The only thing you need to so is make sure that whichever user you run tomcat as has write permissions to the logs, conf and work directories (those are the only ones Tomcat writes to I think). This doesn't have to be 'nobody' though. You could create a tomcat or www user for example. And if you want it to be owned by root, that's fine, just use the group permissions to set the write access.

Re: Automatic reloading of modified .jar/.class files
Yes it does, but it is a significant performance impact to enable it (it's enabled by default).

Re: starting Tomcat at boot time on Linux
try appending an '&' to the end of your start line. That will fork the process to the background. Sometimes when you don't do that and you log out, the process will stop. Worth a shot . . .

Re: JDK 1.3 - Tomcat 3.2
I use the IBM 1.3 JDK on Linux and the Sun 1.3 JDK on Solaris. Both of them work well with no Tomcat specific issues. You'll need to make other code changes to get up to date with any deprecated APIs, but that's not too difficult. The only issue that I found was the Sun JDK on Solaris was not getting a default encoding, so it was not handlin non-ASCII characters in a Cipher method that we have. This was fixed by setting LANG=en_US before starting Tomcat. But this was specific to this JDK/OS and had nothing to do with Tomcat actually.

Re: running as non-root/auto mode?
I wrote a shell script that sets environment variables and then called the tomcat start script. This works well. Then you just need to put it in /etc/init.d/ and make the symbolic links from the appropriate run levels. You can make tomcat run as a non-root user, but only if you want to have it listen on ports above 1024. It has to run as root to bind to port 80 and doesn't have the ability (like Apache) to change user after the binding takes place. You can do something like: su - www -c '' to get it to run as a non-root user in a startup script (with GNU su at least, I don't think the BSD version has the -c switch).

HTTPS to HTTP proxying
Ok, so I have a situation where we are doing an HTTPS to HTTP proxy. Essentially a proxy recieves the HTTPS request, makes an HTTP request to the server with Tomcat running standalone and then the response is returned through the proxy back to the user. So, I access something like: https://somehost/index.html and there is a redirect in it like: out.sendRedirect( "nextpage.html" ); Tomcat in this case will return the user to http://somehost/nextpage.html (notice no https). This makes some sense because Tomcat sees the scheme as HTTP not HTTPS. The odd part though is that this same setup worked with Java Web Server. Anyone know how to handle this other than rewriting all of the redirects to absolute URLs?

Re: Odd error
Oh yeah forgot about ping being ICMP. :) I'm going to look into exactly what the 'heartbeat' is. I think it opens a connection and then doesn't send a request - but that's speculation. I agree that the more robust method would be to actually do a GET and see the results (maybe to a specific file and it can look for a keyword or something). I'll avoid the 'fork' route if at all possible cause I'm lazy and don't want to maintain a patch that won't get included in the main distro. :) Thanks for the thoughts . . . "Craig R.

Re: Odd error
Reply to myself. :) So after some more digging, I find out that it's caused by a 'heartbeat' monitor that we have on our servers to check the status. It pings port 80 to check if the webserver is alive. Apache does not log this in it's error logs as a Connection reset, but running Tomcat standalone does. Is this a bug? No request is actually being made, just a ping to port 80 . . .

Re: Howto share objects between mutiple jsp pages
We run multiple sites on a single machine all that use the same servlets. We put our JARs in the $TOMCAT_HOME/lib directory and it works like a charm. The normal rules apply to Objects, static data is shared among all instances, etc. Is that what you were asking? I think the same thing is accomplished by having a CLASSPATH available to tell tomcat where to find a package. > mall wrote: > > > Can anybody tell me if it is possible for the container(tomcat) to > load an object and to make > that object available to all the pages/servlets contained within the > container?

Re: mod_jk.so
On RedHat (and many Linux distributions) - the apxs and header files are provided in an apache-devel package if you installed it from an RPM or DEB or the like. If you installed from sources you would need to look under the base directory where you installed it, possibly under /usr/local for example. Hope that helps.

Re: How do I assing more memory to Tomcat
I put that in a wrapper script that I use to start and stop tomcat using the script that is shipped with the tomcat stuff. I also set the CLASSPATH, JAVA_HOME, TOMCAT_HOME, etc in that script so that it is really easy to just run the script and not have to worry about setting environment variables.

Re: How do I assing more memory to Tomcat
The TOMCAT_OPTS are really just JVM parameters. e.g.: TOMCAT_OPTS="-Xms16m -Xmx128m -native" or TOMCAT_OPTS="-Xms16m -Xmx128m" Run 'java -X' to get the options that your JVM supports. > Carlos López wrote: > > Hola > > I nedd to assing more memory to Tomcat how do -I do this. > > Where can I find more information about TOMCAT_OPS > > Thanks -- --- Geoff Lane <[EMAIL PROTECTED]> - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

Re: Can't shutdown
On Unix, use ps to see if there are still Java/Tomcat processes running. If so, you'll need to kill them manually before you can restart Tomcat. I included method to kill all the remaining threads in the rc script that I sent to the list yesterday. I've seen this on the IBM 1.3 JDK for Linux.

Re: So can no one help with my Socket Write Error Question ?
Ok, I'll take a shot in the dark. :) Is there a file called 'tomcat-power.gif' in your $TOMCAT_HOME/webapps directory? If so, what is likely happening is that Tomcat is trying to auto configure a context to /tomcat-power.gif - and since it can't expand it or find a WEB-INF/web.xml inside it doesn't know what to do. Just a guess, try moving the file and see if that changes anything.

This will work for both Solaris or Linux. Be sure to edit the
environment variables for your setup.
The process is a bit different for each of them on how to get it to
start on boot. With Red Hat at least, there is a utility called
'chkconfig'. After you copy this file into /etc/init.d - run 'chkconfig
--add tomcat'. Then run 'chkconfig --level 345 tomcat on' to turn it on
for runlevels 3, 4, and 5.
Hope that helps.

Re: oracle blob problem
Eric: I've never experienced that problem exactly, but you might need newer Oracle JDBC drivers. There is a classes12.jar which is what we use. Don't know if that will solve the problem, but it's worth a shot. And for what it's worth, there's a serious bug in the Oracle drivers. NEVER call Statement.setQueryTimeout() - If the query returns within the time set, the thread will go to sleep and become a zombie . .. banged my head against a wall for quite some time before I figured that one out. :) Good luck.

Re: Running Tomcat as non-root user
Kitching - Thanks for the response. I was afraid of that. 'ifconfig' is the utility that lets you see information about the network interfaces, not a firewall. :) Do you run multiple machines with a firewall in front of them to do the redirection (w/ load balancing for example) or do you run the firewall on each machine individually? I asked our operations people about the same thing being done in our load balancer (F5/BigIP) - but apparently it can't be done there. Setting up a redirect on each machine could be a pain - not that I'd have to do it. :) Thanks again.

Running Tomcat as non-root user
In the Tomcat UG under the heading 'Modify and Customize the Batch Files' it says one of the reasons to do so (modify start up scripts) would be: "To switch user from root to some other user using the "su" UNIX command." This is an excellent idea from a security standpoint. But to bind to port 80 (instead of the default high port 8080) root is needed. How many applications do this (Apache for example) is to initially run as root, bind to port 80, and then drop root privileges. Is something like this possible with Tomcat running standalone? Running concurrently with Apache would accomplish this because the AJP connection could be run as any user since it's on a high port.

I've noticed the same thing with mapping a servlet to an index file (in my case I mapped it to index.html).

What I found - and prefer - is to put shared JARs in the $TOMCAT_HOME/lib directory. All of the applications will find them then and share the same ones. They can also be found/loaded if they are set in the CLASSPATH (on Unix I have a wrapper script that sets this before starting Tomcat). One example of something you have to have in the CLASSPATH and not the lib directory is the j2ee.jar if you access it - Tomcat won't start with it in the lib directory (probably because it declares the servlet stuff agina). > Any thoughts will help.

But it is completely optional. I'm exploring Tomcat at work and chose to intentionaly not use webapps so that we would force ourselves to explicitly control the configuration of the application. So, that being said, one thing you could do: in your server.xml file create a context or a virtual host and map it to the directory where the Apache docRoot lives. E.g.: (Forgive any errors, this is from memory) Then under c:/htdocs you'll need your WEB-INF directory with it's web.xml file mapping *.jsp to the JSP engine, etc. I've never done this with JSPs, but it works with static files and servlets so I don't see why it wouldn't with them. Don't know if these are Best Practices, but they're working so far for me. :) -- --- Geoff Lane <[EMAIL PROTECTED]> 'For a list of the ways which technology has failed to improve our quality of life, press 3.' - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
