RE: Simultaneous request from same IP
Let us apply Occam's Razor here. You probably haven't heard of it so I will
repeat it here and show the application to your situation. Quite simply, it
says that when you have two competing theories to explain something, the
simplest theory is usually the correct one.
So, let's apply this:
Theory 1 proposed by you: Tomcat is horribly broken, and unthread safe. It
has major problems processing more than one simultaneous request to a
servlet and no one but you has noticed this. Hundreds or thousands of
developers and applications have not heretofore brought this to light, but
you have.
Theory 2 (proposed by several people on the list): Your application is not
thread safe, and is broken.
Occam's Razor says that your program is broken, and you need to fix it.

TrafficCop is thread safe because add() is synchronized. Regardless if
trafficcop is thread safe or not the values that I get from
HttpServletRequest should not be the same. If I were to take TrafficCop
out of the servlet, I would get the same results in my servlet. I guess
what I am saying is that TrafficCop should have nothing to do with the
behavior that I am seeing inside the servlet. Right?

But the same trafficCop instance is being used at the same time for 2
differnt requests.
The trafficCop object has a method called add() which (seems to) acts
on instance variables inside of the trafficCop object. This makes the
trafficCop object not thread safe.

Why does that effect the HttpServletRequest object? If you look at

RE: Request/Connection Timeout
As others have said, you need to re-design your app. Personally, I would initiate the computation in a background thread and mail the results to the user as a PDF document. Further, I would use a queue design so that only one computation is running at a time. What will your app do if the user hits back, and keeps re-submitting? What will your app do if Monday morning, 40 managers come in and request a big report? George Sexton MH Software, Inc.

RE: Java returns bunk date!?
If you don't need the time portion, I once wrote a replacement for the calendar that handles just dates. Unlike all of the bizarre manipulations required by a calendar, with mine you can just call object.add(7) to add 7 days to a date. It uses an internal Julian date field. Checking for elapsed number of days is a straight integer subtraction. It pretty closely mimics the date capabilities of xBase variants. Personally, I never use calendars. They are just too obtuse and error prone. If you are interested you can view the Javadocs at: http://www.mhsoftware.com/resources/jar/doc/ The class name is SaneDate.

RE: windows iis machine + linux tomcat machine
You could use SMB to mount the files from the Windows machine to the Linux machine. If you need high performance, this will have a hit. Alternatively, you could write a shell script that will sync the files on Windows over to the Linux machine using ftp. ncftpget is pretty nice for an ftp program that could keep them in synch. If you have to have immediate updates, then SMB is the way to go. If you can live with a delay of a few minutes, then an FTP program is the way to go. -Original Message- From: Jose Antonio Martinez [mailto:lfbbes;yahoo.es] Sent: 12 November, 2002 1:55 PM To: Tomcat Users List Subject: Re: windows iis machine + linux tomcat machine i know.

We don't use it in that way. We have a load balancer in front of our nodes, which has a standby balancer, if the first one goes down. If we want to get your requested behavior, we had to configure this on our load balancer, not on the nodes. This balancer knows nothing about apache, tomcat and mod_jk. So I don't know how to manage it with mod_jk. I don't know how your config should work. Because if N1 routes to all other nodes and N1 goes down, how should your client know, that he had to connect to N2? You need some logic in front of your cluster, that the clients see your cluster as one big server. If you want something like standby or hot standby you must implement this in the front logic, not on the nodes. And I don't know if this is possible with jk1. Why do you limit the balancing to N1? Most of the work is done in your servlets. The balancing is not so hard, that it will bring your node down. If all nodes do balancing its no problem, if one node goes down. But may be I don't understand your scenario. Bernd Alexander Piavka wrote: Bernd thanks for your reply. There is one more question i have. I have 3 nodes N1,N2,N3 each runs apache and tomcat.

On node N2 i want to run lb_worker2 which will start routing all requests between all nodes ONLY then lb_worker1 goes down. I don't know if it is possible to make this configuration in workers.properties file.

And bl_worker1 should have very high lbfactor and bl_worker2 very low: worker.bl_worker.type=lb worker.bl_worker.balanced_workers=bl_worker1,bl_worker2 but this is probably illegal as load balancers don't have lbfactor, and balancers can't have other balancers in their balanced_workers property.

RE: Question regarding long running web applications
You need to take an off-line approach where the servlet places a job request into a job queue, and another application (or perhaps a servicing thread inside tomcat) services the request and mails it to the user.

At times one or more end-user's request may take several minutes possibly up to an hour to complete.I am attempting to plan for a worst case scenario that has all end-users making requests that take up to an hour to complete. From my understanding of Tomcat it is possible to configure how many requests can be processed at one time and how many can be on a queue waiting. In my scenario, it is possible that all requests processing could be waiting on data from the mainframe, yet Tomcat and the Web server itself would have cycles to process requests queued waiting. I'm wondering whether there is a way with Tomcat/Servlets that I might set up my own worker queue and thread pool to process requests; keep the connection with the end user (client) active and free up tomcat requests for additional processing?

String secretCode = secret;
if(paramPassword != secretCode)

There is a bug in IE dealing with re-directs and SSL. I forget how it works but it went something like this: Login page invalidates session. User enters user ID and password. Login page re-directs to target page IE Generates spurious additional request to login page which again invalidates the session. If you have pages that invalidate the session, you might want to take a look at them.

RequestDispatcher dispatcher =

There are a couple of issues here. - if ServerName in httpd.conf is 127.0.0.1, then that is what you put in the URL - 127.0.0.1 = localhost, on every computer in the world, it's a standard - do you have a hosts file or some other DNS setting that is resolving jk.mshome.net to 127.0.0.1? Basically, things have to match. If jk.mshome.net = 127.0.0.1, then jk.mshome.net should be your ServerName in httpd.conf. My advice is to reinstall Apache, and don't answer _anything_ when asked for hostname, IP address, or anything else. Let the installer figure that stuff out on its own. You can't just type hostnames willy-nilly, they have to resolve correctly for services that are looking for them to work correctly. Since jk.mshome.net does not resolve publicly, either set up DNS on your LAN or a local hosts file on your PC to resolve the name. Otherwise, don't use it anywhere, in any configuration, because it won't work. Typing ping localhost should return an IP address of 127.0.0.1. Typing ping jk.mshome.net should return nothing. Apache should be set to defaults, across the board (localhost).

Subject: Symlinks
Hi All,
Is there any way to tell Tomcat to not follow symlinks?
If not how
can I protect my server against malicious symlinks? Is the
java.io.FilePermissions smart enough to figure these out?
For example if I give read access only to directory foo through the
java.io.FilePermissions, but inside of foo, there is a symlink that
points to a file bar, which really exists outside of the directory
foo. Is the Security Manager smart enough to catch this.
I have also found that while I can't see a WEB-INF directory from the
browser using a URL like so:
http://myserver:8080/myapp/WEB-INF/,
I can create a symlink in $CATALINA_HOME/webapp/myapp/ which
points to a
WEB-INF directory, then I can see that directory as plane as day. How
can you protect your server from these sort of things.
Thanks,
Denny

In the included servlet i added the following lines after the /HTML tag

try {

RE: problem using sendRedirect() in a servlet jsp:include'd into a jsp page
A couple of things: 1) Generally, you cannot do a send redirect if you have already written something to the output stream. 2) Unlike ASP, sendRedirect() does not terminate processing of the current servlet, or JSP Page. You need to explicitly put a RETURN statement in. In your case, since you are doing the send re-direct from the servlet, what you should do is set an attribute on the request, and have the JSP page check for the attribute. If the attribute is present, signalling a redirect, the JSP page should similarly execute a return statement. George Sexton MH Software, Inc.

RE: Where should i put dynamically generated graphics
It depends. One way I have done it is to have the generator servlet save it on the session, and have the page the generator servlet writes make a request to a simple servlet that returns the graphic, and then deletes it from the session. Another way would be to write it to the temp dir. From the Servlet API Spec: SRV.3.7.1 Temporary Working Directories A temporary storage directory is required for each servlet context. Servlet containers must provide a private temporary directory per servlet context, and make it available via the javax.servlet.context.tempdir context attribute. The objects associated with the attribute must be of type java.io.File. Then, using a servlet mapping request the generated image and have the servlet retrieve the temporary image. I guess that you could make another dir writable to the server, and store the image in their natively. George Sexton MH Software, Inc.

Is it possible to configure the Statement so that the Insert row in the Result Set gets updated when the insert takes place and the 'id' gets generated? There are two ways of doing this. The first one is to use a stored procedure to do the insert/update and have it return the value. The second , and I haven't tried this would be to pass a compound statement insert into ...; select @@IDENTITY. I will give you one final warning about @@IDENTITY. If your statement invokes another statement (trigger, etc) that performs an insert into a table that contains an identity, you will receive the value of the last created identity, which probably is not the one you expect.

RE: Arabic content
I have done Hebrew before, and it's pretty much the same problem. The major issue is that you have content that is Right to left, and content that is left to right. Since it is a single-byte language, you don't have to use Unicode, you just have to set the code-page to the right value. RTL support is getting better. Last I checked (a few months ago), IE was the only one that supported it fully. Mozilla does support it, but when you have LTR text embedded inside the page (Company names, English Names, Numerals, etc), the rendering engine doesn't handle it. So, you are pretty much going to be limited to IE as a client. If you are using graphics, particularly things like pointy arrows, they will be pointing the wrong way when you set the DIR=RTL attribute for the body.

CATALINA_OPTS=-server -Xms1024m -Xmx3072m Should give me a range of 1-3 gigs. When I restart Tomcat, however, this doesn't appear to affect anything. I'm running a simple memory servlet, as suggested by Yoav Shapira, to simply create a whole bunch of memory, but it still caps out as if it were using the defaults. Couple questions: 1) Must I restart the machine for the CATALINA_OPTS to take effect (or, what is wrong with my environment variable)? In my experience this has not been necessary, only restart the application/process. (Maybe this is a WinNT4 quirk or something similar). 2) Tomcat's configuration files most likely support what I'm trying to do. Is there an appropriate/recommended place I define this envirnoment variable? Quick config rundown: JDK 1.4, WinNT4 (or 2K), Tomcat 4.0.4.

I really doubt it. I seem to recall that for Windows 32 bit applications the maximum address space of an application is 2GB.

RE: Resend: Tomcat Connection Management/Performance
Just out of curiosity, does your test bed do HTTP 1.0 requests, or HTTP 1.1 requests?

RE: Resend: Tomcat Connection Management/Performance
This would be worth verifying. I just used telnet to play with the HTTP connector. HTTP 1.0 requests are closed immediately after the data is sent. HTTP 1.1 requests are not closed until 60 seconds have elapsed. The HTTP connector also seems to ignore the Connection: Close directive. You can verify this behavior by using telnet to connect to the specified port and doing some manual requests: GET /your_servlet_URL HTTP/1.1 Host: yourhostname.com and press enter twice. -Original Message- From: Marinko, Jeff [mailto:[EMAIL PROTECTED]] Sent: 14 August, 2002 3:57 PM To: 'Tomcat Users List' Subject: RE: Resend: Tomcat Connection Management/Performance I'm fairly certain they are 1.0 requests. -Original Message- From: Sexton, George [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 14, 2002 2:49 PM To: Tomcat Users List Subject: RE: Resend: Tomcat Connection Management/Performance Just out of curiosity, does your test bed do HTTP 1.0 requests, or HTTP 1.1 requests?

RE: Resend: Tomcat Connection Management/Performance
My personal theory is that you are making 1.1 requests, and the background thread isn't getting around to closing the connections. You could specify: Connection: close as a header so that tomcat will immediately close the connections. The lower case version does seem to be honored. -Original Message- From: Marinko, Jeff [mailto:[EMAIL PROTECTED]] Sent: 14 August, 2002 4:29 PM To: 'Tomcat Users List' Subject: RE: Resend: Tomcat Connection Management/Performance I've verified the behavior. The connection is closed roughly 5 seconds after I request it (my timeout is set to 5 seconds, so that makes sense). Although that makes sense, since we specified a 1.1 request...

RE: Writing files from a class
From the servlet 2.3 Specification: SRV.3.7.1 Temporary Working Directories A temporary storage directory is required for each servlet context.

The objects associated with the attribute must be of type java.io.File. -Original Message- From: Stephen Bacon [mailto:[EMAIL PROTECTED]] Sent: 13 August, 2002 5:20 PM To: [EMAIL PROTECTED] Subject: Writing files from a class Hello, I'm trying to migrate from Tomcat 3 to Catalina (under Linux) and I've hit a snag. Several of my custom classes which I use from JSPs (e.g. ConnectionPool) print messages to debug files which I access via: snip pwDebug = new PrintWriter(new FileOutputStream(m_sDebugFileName, true)); pwDebug.println(m_sdf.format(new java.util.Date()) + + sparMsg); snip Previously, it would create / append to the file in the location that Tomcat was started from (so I had made sure it was always done from a logs directory - a kludge yes, but it worked) Well, Tomcat 4 seems to have added security which is blocking this. I made a modification to pull the debug file name from the web.xml file and made sure the target directory specified (/var/tomcat4/webapps/appname/logs) was owned by the user tomcat4, and had the write flags turned on. No go - still no debug file (it writes an init message so there should be something) This of course is a big problem because my classes have now all become black boxes and I'm unable to debug problems. Is this something to do with security under T4? Is there a proper means by which messages should be logged? Have I configured something wrong? The app seems to be running OK, but I have no way to be sure without the ability to print debug messages.
