Re: What can url-pattern accept?
I ended up with something interesting with tomcat. I basically have two security-constraint, in the first one I put url-pattern*.do/url-pattern and in the second one, I put url-pattern/admin/*/url-pattern. Tomcat just did what I want, the user with role matching the first constraint does not have access to anything /admin/*. It works in both Tomcat 5.5 and 6.0. It is probably not the specification complied solution. But good enough for me now.

In this case the servlet path is the request URI minus the context path and the path info is null. Actually, I don't think that Tomcat supports url-pattern//url-pattern (although it clearly should under the very brain-dead wording of the spec here). There seem to be other spec violations in Tomcat here, since if you have a one security-constraint for *.do, and another one for /admin/*, then Tomcat considers both of them for a request to /myapp/admin/foo.do. However, the spec (at least for v2.5) says that only the /admin/* constraint should be considered. And this is where the brain-dead part kicks in :(, since Tomcat's implementation makes more sense than the spec. Hopefully someone will fix this in the Servlet 3.0 spec. - All other strings are used for exact matches only. In other words, /admin/*.do is not a valid way to match what you want, since it will match only /admin/*.do, literally. For 20 years at least, there have been 2 widely-used pattern-matching variations in existence : - the file glob kind of pattern, where * anywhere matches any number of characters and ? anywhere matches one character - regular expressions Why the designers of the servlet API found it useful or necessary to invent yet their own different way of matching wildcards, and a rather brain-dead one at that, is beyond me. But so it seems to be. This being said, it seems that there exists a servlet filter which allows much more flexibility. I have not tried it myself yet, but I have seen a lot of nice things written about it.

tomcat 5.5 unicode issiues!
Hi, I have some files in my site that contain some characters that the tomcat 5.5 dont parse them correctly and thus I get 404 error file not found. For instance the file names are: bbb%e2%80%99s-bbb-.htm ggg-xx-eee’s-car.htm got-it….htm catch-a-f….htm this file ‘to-catch-a-thief….htm’ is being translated to this ‘to-catch-a-thief%E2%80%A6.htm’ by tomcat. Do I need to configure something to the tomcat so I would be able to parse it well. Thanks in advanced

Dual-Independent Tomcat servers, on Single Win32 host sharing IIS server.
Hello, Can anyone guide me in the right direction with my issue. Windows Server 2003, IIS 6.0, tomcat-connector 1.2.8, and Tomcat 5.0.16. I have been tasked to do the following. To get two separate Tomcat server instances running on the same host independent of each other and working off of the same IIS server (compliments of the Tomcat-Connector, and ISAPI-Filter). Getting the two servers up and running together is the easy part, and has already been achieved. They both have unique ports, and IP addresses from each other.. MY issue is the isapi filter. The workers.properties.minimal uses 8009 for ajp13, and 'localhost' worker.list=ajp13w worker.ajp13w.type=ajp13 worker.ajp13w.host=localhost worker.ajp13w.port=8009 There has to be some information out there that will guide you to create a custom workers.properties.minimal file. One of my two Tomcat servers has port 8009 assigned, and the other is using port 8109. I am assuming that I was correct on thinking this port needed to be unique from the other Tomcat server on the host? I tried to do the following, and it did not work. worker.list=ajp13w worker.ajp13w.type=ajp13 worker.ajp13w.host=192.168.0.1 worker.ajp13w.port=8009 worker.list=ajp13w2 worker.ajp13w2.type=ajp13 worker.ajp13w2.host=192.168.0.2 worker.ajp13w2.port=8109 ..and then in my uriworker.properties file /servlets-examples/*=ajp13w /jsp-examples/*=ajp13w2 I thought this would work, but clearly I am looking at this from the wrong angle. Can someone please guide me to where I can get the information to either re-write custom workers.properties.minimal and uriworker.properties files.. or what is it that I am doing wrong here. -thx *d03*

Shahar, what Mark and in a more verbose way Johnny are trying to tell you, is 1) the first problem is to figure out how and why these files arrived on your system's disk with such names, and if possible correct that. They are not normal names for files, and could give you any kind of trouble in the future, such as when you will try to do a backup of your server, or list them in directories, or sort the filenames alphabetically, or access them via DAV or Samba, etc.. etc.. 2) changing the URIEncoding on your server to UTF-8 is also not something you should just do lightly and unilaterally, because you may then have problems with browsers who will *not* send request URI's as UTF-8. By default, most browsers will not, so unless you know and control who is going to access your server with what and from which pages, you are probably creating an even bigger problem for the future.

Re: Custom error page with stacktrace
In your error page, the variable exception is set to the exception
(if any). You can get the error message and stack trace from the
exception like this:
pException message: %= (exception == null) ? :
exception.getMessage() %/p
%
String stStack = ;
if (exception != null) {
java.io.StringWriter sw = new java.io.StringWriter();
exception.printStackTrace(new java.io.PrintWriter(sw));
stStack = sw.toString();
}
%
pStack trace:/p
pre
%= stStack %
/pre
(Note: For clarity I omitted some important stuff like sanitizing the
output to prevent people from stuffing nasty HTML/Javascript into the
error messages.)

Is this a stock tomcat, one from the ports, or maybe a particularly old one? catalina.out is set at the catalina.sh: $CATALINA_BASE/logs/catalina.out 21 This file is not rateable, as it is jsut a redirection. You are right. Woops, I thought it was a rotatable file. Maybe I restart my Tomcats too often. :) We are thinking in moving this redirection to /dev/null or just remove the redirection. Is it a sense thing to do? To get rid of an ever-growing file, yes. However, you have to make really sure that you still get all the stack traces and whatnot that is in that file, only get them into a rolling file. A. Wait. Now I know why I never run into this. I run my Tomcats in screen using catalina.sh run, so catalina.out is written to the console instead of a file. I do get a nice daily log e.g. catalina. 2008-08-20.log. That would mean it is safe to redirect catalina.out to /dev/null, as long as you have the daily logs. -- Kees Jan http://java-monitor.com/forum/ [EMAIL PROTECTED] 06-51838192 Human beings make life so interesting.

Mod_proxy apache balance to 1 Tomcat app works, fails with another?
I am a newbie to Tomcat. I am tasked with deploying a couple of applications from our software vendor. I am an Oracle DBA, not a software developer, so this question is probably very rudimentary. I have read the 'Tomcat Definitive Guide', and used it to set up load balancing for the 2 applications the software company developed. The applications work fine standalone, but we have 3 application servers I am trying to load balance. I am using apache's mod_proxy to load balance 3 tomcat servers that have 2 different apps on them. One of the applications works fine, but the other one gives a 404 error. To make sure it was load balancing correctly, I installed an instance.txt in the application's directories - webapps/aalTA and aal_pa. When I try the aal_pa application, I see the load balancing is working correctly. When I try the aalTA application instance.txt, again I get the 404 error. I can get to both applications directly, so all is working there. When I go to the aalTA application using the load balancing, the error message from Tomcat is The requested resource (/aalTA/servlet/LayoutMgr%3FLAYOUT=/aal/aalApp1_login/instance.txt) is not available. When I go to http://sisapp4:8080/aal_pa/ directly, the URL does not change. When I go to http://sisapp4:8080/aalTA/ directly, it automatically adds servlet/LayoutMgr?LAYOUT=/aal/aalApp1_login to the end of the URL. Is there something I can do to make this work, or is it just that this application cannot work with Apache load balancing?

Instructions for setting up CGI
I looked at the page for setting up CGI on Tomcat 6, but the paragraph that follows leads to some confusion. Remove the XML comments from around the CGI servlet and servlet-mapping configuration in $CATALINA_BASE/conf/web.xml. Apparently the jar the XML file refers to no longer exists. And it isn't clear where to put my perl scripts, or if I can place them in, say, a cgi-bin directory located where all my web apps can access and use them. Is there a document providing instructions on how to set up CGI that is both complete and correct for Tomcat 6? I would suggest, though, that http://tomcat.apache.org/tomcat-6.0-doc/cgi-howto.html; be ammended to at least say what parts of the cgi stuff in the xml file can safely be ignored because it refers to Tomcat 5.x, and describes what is needed for a globally accessable ci script repository. I find the combination of the xml file referring to an old Tomcat with the above mentioned web page confusing.

Multiple Websites on IIS using SSL
I was looking for some help here. I have 2 websites - unique URLs using SSL using IIS with asp.net with JRun to run servlet code. I need to convert jrun to tomcat. I need to keep IIS and use ISAPI redirect. Using Tomcat with SSL - do I need to run 2 instances of tomcat for each unique URL and have a unique certificate per Tomcat instance? or can I Run one instance of tomcat with one certificate that the 2 URLs can call servlets?

HOW TO install/setup 2 instances of tomcat on same server
I know this question has been asked a lot but I've read different solutions depending on the needs of the problem. I need to have 2 instances of tomcat on the same server for the same application. One would be for production and the other for development (which can be start and stopped whenever without affecting the production one). From my understanding i need to have each instance on different ports and modifying some other files but what I am missing is the technical things. Can any one please guide me on the correct direction so that i don't mess up anything! I've never worked with Tomcat that is why i have no idea on how to do it.

This is at the same time some information for you, the Original Poster (OP), and a question for the others on this list more Tomcat-qualified than I am. But we've got to start somewhere... To the OP (and the others to contradict me if I'm wrong) : You do not necessarily need two separate instances of Tomcat. Under Tomcat, each application can be started and stopped (and even a new version reloaded) without stopping the Tomcat server. You would just need to name your applications differently. (like http://host.mycompany.com/real-app; and http://host.mycompany.com/test-app;). There also exists the possibility to run one Tomcat with different Virtual Hosts, on the same port 80.

I am mentioning the above two possibilities because, you knowing not much about Tomcat to start witj, either one of the above is probably easier to set up than two separate Tomcat instances. The difference between the above solutions and two really separate Tomcat instances would be if the test application could really crash the whole server, in which case you may not like one of the above solutions.

Another confused person trying to get jconsole to monitor tomcat.
I've been through the docs. I've been through Google. I can't seem to figure this out. Server: Tomcat 6.0.18, JDK: 1.6.0_07, Redhat Server 5.2 Client: jconsole from JDK 1.6.0_07 on Windows XP I've got all of these in $CATALINA_OPTS and they do show up in the java command line when I run ps: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false The Redhat server is running iptables and disallows most things that aren't 80/443. Any other ports that are needed are generally opened up only to specific IP's. I've opened up the JMX port specified above on the Linux firewall: iptables -A INPUT -s myClientsIp -p tcp -m tcp --dport 12345 -j ACCEPT I run jconsole: C:\PathToJava\binjconsole myServer.myDomain.com:12345 It can't make the connection. I've got a feeling it's something to do with the firewall. I've seen some stuff that suggests that there's another unspecified port opened up but it didn't really make sense to me. Note that the server and the client are at different facilities connected over the internet which is why I eventually want to get it going with authentication and SSL but I can't even get this simple insecure version of the connection to work. - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

A test Tomcat does not necessarily need a big server, and your average clunky PC running Linux would probably do fine. (It does need some RAM though). That would be a lot easier to install, because you could have on each just a Tomcat out-of-the-box.

Tomcat can't see a new function

In one jar library, I can create new functions, rebuild the library, and when I put them up in Tomcat 5.5 WEB-INF, it recognizes them. However, I have another library jar file that use to work, but now I can't seem to add any functions to any of the files and have them seen by tomcat. They work fine in the Borland debugger, but I get this error in the log file from Tomcat. I tried creating a simple 10 line program and trying to call a new function in any of the files in the jar library file, and it doesn't see them. However, tomcat does recognize the original functions that each file originally had in them, and they work fine. It's only new fuctions that don't work. Any ideas? This one is a real bugger.

Receiving duplicate requests when code that processes the initial request blocks for a long time ...
Hi,
I am not sure if this is a bug, feature, or whatever but I definitely need
some answers here. I ran into some issues when sending a request to a
servlet that executes native code that takes a long time to terminate (I am
talking 10s of seconds here). I am consistently getting a second, sometimes
a third, duplicate request about 6-8 seconds into the execution of the
initial request. After alittle investigation I realized I could replicate
this issue by replacing the code that executes the native code with an
infinitely blocking loop ... while(true). As I said before sometimes I even
get a second duplicate request which has me thinking that this is
unexpected/unintended behavior. Here is a small snippet of code that should
allow you to replicate the issue:
public void doPost(HttpServletRequest request, HttpServletResponse response)
{
System.out.println(request);
while(true);
}
In the interest of full disclosure I have a lot more code than what you see
in the provided snippet and I have not tested the aforementioned code
snippet. I have replicated the issue on a dedicated server and a local VM,
both running CentOS 4.5, Java SE 1.6.0, and Tomcat 6. If this is a feature
is there a way to turn it off? If this is a bug is there a workaround?

Mashama

Re: HOW TO install/setup 2 instances of tomcat on same server
edponce wrote: I know this question has been asked a lot but I've read different solutions depending on the needs of the problem. I need to have 2 instances of tomcat on the same server for the same application. One would be for production and the other for development (which can be start and stopped whenever without affecting the production one). From my understanding i need to have each instance on different ports and modifying some other files but what I am missing is the technical things. Can any one please guide me on the correct direction so that i don't mess up anything! I've never worked with Tomcat that is why i have no idea on how to do it.

Each one of these virtual hosts would have a different DNS name (like realserver.mycompany.com and testserver.mycompany.com) and could have a different directory where the applications reside, but the application itself would be named the same way. The difference between the above solutions and two really separate Tomcat instances would be if the test application could really crash the whole server, in which case you may not like one of the above solutions. Comments anyone ? When I was new to tomcat (arguably when compared with some members of this list, I could still be considered new), I found it conceptually easier to work with two instances, as you don't need to switch context names etc when you want to deploy live. Whilst a little cumbersome, and inefficient from a resource usage standpoint, when you're learning, being able to restart tomcat as you shop and change the server.xml file etc can be useful, without fear of breaking the production service. It can also be useful for evaluating a new version before you unleash it to production. edponce: If you want to run two instances, the easiest way, to my mind, is to duplicate the tomcat directory. On the duplicated tomcat directory, you need to edit the server.xml file so that the second server.xml as unique ports for the shutdown port, the interface port (eg 8080 could become 8081 etc). Once you have made these changes, you should be able to start each of them up by running their respective startup scripts. You could achieve the same using links and a few other sharing techniques, but for simplicity's sake, I think this approach to two instances using duplicated directories is the most robust. Tom
