Re: Tomcat does not unpack WAR file (Tomcat 5.5.20)
It turns out that the problem IS connected to the ROOT.xml file under conf\Catalina\localhost. As soon as I remove ROOT.xml, the ROOT.war unpacks. This is what my ROOT.xml file looks like: Context cookies=false path= debug=1/ There has been some prior discussion around this topic.

Re: Tomcat does not unpack WAR file (Tomcat 5.5.20)
I may be going slightly off-topic for this thread, but I have 2
questions regarding the ROOT.xml ROOT.xml fragment file...
As a test, I removed ROOT.xml and tested the app behavior. Specifically,
I performed these steps to remove the ROOT.xml fragment file:
= I removed ROOT.xml from ...conf\Catalina\localhost.
= I stopped Tomcat, deleted the 'work' folder and started Tomcat again.
= I cleared all cookies from the client machine's web browser.
The ROOT.xml file that I removed looked like this:
Context cookies=false path= debug=1/
What puzzles me is this:
1. In order to map the ROOT web context to the root URI ('/'), I
included the (path=) attribute in ROOT.xml.
However, even after removing the ROOT.xml fragment file, the ROOT web
app is still mapped to the root URI ('/') i.e. when I navigate to the
server's root domain name, the ROOT wabapp is invoked.
Was I mistaken in thinking that the (path=) attribute is required?
2. Similarly, I included the (cookies=false) attribute to enable URL
rewriting for browsers that do not support cookies.
However, even after removing the ROOT.xml fragment file, URL rewriting
takes place - IF the web browser does not support cookies.
Have I missed something - or does the (cookies=false) do something
slightly different to what I thought?
Just to re-iterate, I am runningTomcat 5..5.20
Thanks
Pete

Re: HOW TO install/setup 2 instances of tomcat on same server
Hi edponce so if i understood everything i just need to duplicate the tomcat folder, do i need to rename it or something? Yes, you just need to duplicate it. You can call the duplicate folder whatever you like. Then 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) and how can i check if i've done this correctly? that both instances are running? Yes. Check your logs during startup and shutdown also for any warnings or port binding issues. Thanks for your help... You're welcome.

automatic login
Hi all I'm trying to figure out a way to automatically login a user. It arises when they have created an account, and I don't want to then direct them back to a login page - rather, I want to, in this instance, just log them in. I am using Tomcat's container-managed security. I am using CentOS / JVM 1.6 / apache-tomcat-6.0.14. Does anyone know if the API allows this (and if so, how!)? I guess I could implement my own application-managed security, but I'd like to stick with the tomcat implementation.

Hello Update There seems to be another set of outputs. If I do not run the web first and just start it and then run my ajax app, I execute the call to the webapp, but there is no parameter, even though I check both XMLHttpRequest.open(a,b,c) and XMLHttpRequest.send(query). This is a check right before, I know it the proper url. This sort of explains the initial problem cited below, but not how I loose the parameter. Ideas2?

Re: Struts vs JSF (poll?)
Being as most of what I do today is RIA development, I've personally found that the ideal solution is to use NO framework at all. I use DWR and just treat everything as method calls. The nice thing about that is you wind up with a very clean and plain structure to your application in the sense that you're thinking in terms of classes and methods, like you do in general server-side anyway. It also makes most of your application highly testable (except where session comes into play, but we tend to try and minimize that usage anyway). You design a proper API, and the fact that you're using it behind a web-based application isn't really relevant (and in fact you can truly slap any front-end on you want without much trouble). I've found that my projects drift towards more of a component-based model naturally doing this, and away from the classic page/action-based model of Struts (which is where we were a few years ago). It becomes much more about events, small, focused bits of functionality, and how it's all put together to form a larger whole. The development cycle I find is much faster, much simpler and the results are far more flexible and extensible. It's in some sense a return to a more bare metal mentality, but it's truly made our lives a whole lot better. I've had to mentor some pretty inexperienced teams and I've seen this approach versus the framework-centric approach with something like Struts, and I've observed it to be much easier to get their brains wrapped around this approach, they come up to speed and are effective faster, and they are more effective than in cases where a full, proper framework was used. So, if the question is Struts vs. JSF, I'm in agreement with Johnny to a large degree: neither is the best answer. And in fact, I second the no framework at all opinion. I suppose if you wanted to consider DWR a framework then I'd say DWR, but it's really just a mechanism, not a framework (it could be something else other than DWR, so long as it presented an RPC view of the world it'd be the same basically). But as far as the true frameworks go, as we've come to understand them over the past few years, my personal opinion is that they serve no purpose any longer when talking about developing modern RIAs, and in fact tend to get in the way more than they help in those situations. I completely realize this isn't the popular opinion (yet), and many people actually disagree quite vehemently, but I've had pretty extensive experience building these types of apps for nearly 10 years now, and that's the mindset I've come to at this point.

Re: Custom error page with stacktrace
Dear All,
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
You can make this even more readable by using the individual stack
trace elements instead of the string writer. That way you can give
those lines that have your own classes a different colour. What I do
is show my own classes in bold red in the stack trace. That way I know
what code to check faster.
Check out

Re: override 100-continue response in servlet
Dear Craig, I'm writing a servlet to allow large-file uploads (with ranges and resume). One issue I noticed was that if the range is invalid (I do the checks in doPut), and I return a 416, the client (curl in this case) continues to upload the body (possibly gigabytes of data that will be discarded) because tomcat already sent the 100-continue. Ah. Rebuilding FTP? :-) Maybe I could just force the connection to close somehow, but I'd like to respond with the 416 instead of tomcat's immediate 100- continue. Is there a way to override the 100-continue behaviour so I can perform the checks and return 100 or 416 myself? You could use a servlet-filter to do the checks earlier? Other that that, you're looking at hacking Tomcat itself. If not, how could I force the connection to close immediately? response.getOutputStream().close() ? -- Kees Jan http://java-monitor.com/forum/ [EMAIL PROTECTED] 06-51838192 The secret of success lies in the stability of the goal. -- Benjamin Disraeli - 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: Tomcat does not unpack WAR file (Tomcat 5.5.20)
Peter wrote:
I may be going slightly off-topic for this thread, but I have 2
questions regarding the ROOT.xml ROOT.xml fragment file...
As a test, I removed ROOT.xml and tested the app behavior.
Specifically, I performed these steps to remove the ROOT.xml fragment
file:
= I removed ROOT.xml from ...conf\Catalina\localhost.
= I stopped Tomcat, deleted the 'work' folder and started Tomcat again.
= I cleared all cookies from the client machine's web browser.
The ROOT.xml file that I removed looked like this:
Context cookies=false path= debug=1/
What puzzles me is this:
1. In order to map the ROOT web context to the root URI ('/'), I
included the (path=) attribute in ROOT.xml.
However, even after removing the ROOT.xml fragment file, the ROOT web
app is still mapped to the root URI ('/') i.e. when I navigate to the
server's root domain name, the ROOT wabapp is invoked.
Was I mistaken in thinking that the (path=) attribute is required?
2. Similarly, I included the (cookies=false) attribute to enable URL
rewriting for browsers that do not support cookies.
However, even after removing the ROOT.xml fragment file, URL rewriting
takes place - IF the web browser does not support cookies.
Have I missed something - or does the (cookies=false) do something
slightly different to what I thought?
I think so. cookies=true determines if you want cookies to be used for
session identifier. If set to true, I believe that Tomcat will
automatically use URL rewrite if a browser does not accept cookies.
Just to re-iterate, I am runningTomcat 5..5.20

Subject: Tomcat does not unpack WAR file (Tomcat 5.5.20)
Hi
When I drop a WAR file into the webapps folder on my dev machine -
running Tomcat 6.0.16 - Tomcat unpacks it on startup.
When I do the same on the production box - running Tomcat 5.5.20 -
nothing happens.
The WAR file that I am deploying is ROOT.war; there is a
corresponding ROOT.xml under conf\Catalina\localhost. (I'm not sure
if those details have any bearing on the problem - according to one
archived post, there may be a connection.)
On both machines, the host tags look identical:
Host name=localhost appBase=webapps
unpackWARs=true autoDeploy=true
xmlValidation=false xmlNamespaceAware=false
Any assistance would be appreciated. :)

Pete, nothing comes to mind, you seem to have the bases covered...
One possibility is that the existing ROOT web ap is busy...
Maybe a thread running or something... TC will not start up the new
guy, if the old one cant let go..
possibly from the manager console /manager/html tell the old one to
undeploy first maybe...
Also just make sure from you dev environment that the ROOT context
path is
really empty and not root which it maybe doing... wild guess ;)

Re: DWR [Slightly off topic -- Was Struts vs JSF (poll?)]
Frank, This may be too far off-list; if so please suggest another channel. However, there may be other developers lurking on the list who would also be interested. I've downloaded DWR and performed a cursory look through the examples, and it looks promising (I've done a chunk of very bare-metal ajax, and a chunk of GWT). I've also read your blog entry on the subject and am quite convinced about the desirability of an RPC-like framework. What I don't have a feel for is the mix between ordinary html and javascript that might be forced on you by DWR. The item making me hesitant about sticking my big toe in the icy cold water is this: I'm looking at a couple of legacy struts 1.8 apps which need to have some more powerful mini-apps dropped into the pages without completely throwing out the existing pages: think souped-up puzzles, or souped up local database query or souped-up wizard-like expert diagnostic action. I'd hope to be able to at least preserve the tiles-based layout, and even the fundamental struts-control (constraining as I feel about that), just to cut down on the extent of rework. I wonder if you would comment on this. Thanks in advance, Ken On Aug 24, 2008, at 4:10 PM, Frank W.

I've found that my projects drift towards more of a component-based model naturally doing this, and away from the classic page/action-based model of Struts (which is where we were a few years ago). It becomes much more about events, small, focused bits of functionality, and how it's all put together to form a larger whole. The development cycle I find is much faster, much simpler and the results are far more flexible and extensible. It's in some sense a return to a more bare metal mentality, but it's truly made our lives a whole lot better. I've had to mentor some pretty inexperienced teams and I've seen this approach versus the framework-centric approach with something like Struts, and I've observed it to be much easier to get their brains wrapped around this approach, they come up to speed and are effective faster, and they are more effective than in cases where a full, proper framework was used. So, if the question is Struts vs. JSF, I'm in agreement with Johnny to a large degree: neither is the best answer. And in fact, I second the no framework at all opinion. I suppose if you wanted to consider DWR a framework then I'd say DWR, but it's really just a mechanism, not a framework (it could be something else other than DWR, so long as it presented an RPC view of the world it'd be the same basically). But as far as the true frameworks go, as we've come to understand them over the past few years, my personal opinion is that they serve no purpose any longer when talking about developing modern RIAs, and in fact tend to get in the way more than they help in those situations. I completely realize this isn't the popular opinion (yet), and many people actually disagree quite vehemently, but I've had pretty extensive experience building these types of apps for nearly 10 years now, and that's the mindset I've come to at this point. (I tend not to say this often, because it's usually annoying to me when people do it, but what the hell... I actually blogged about this a little while back: http://www.zammetti.com/blog) Frank Yes, exactly... the closer you get to the plain TC MVC model (its a technique not a framework), the smaller, cleaner, faster, and easier to understand... the code becomes. Then what you'll find is that if you need Ajax, you may give DWR a go, or anything else... and then if your client comes back and says, we need a special wiki with a search engine... you not going to panic because its not in the framework... you going dig around in Apache, find some cool stuff like lucene... and just do it. Its a model... and once you get it, you'll actually start to see it in all these other tools... I actually think there is no short cut to just trying to understand all the core technologies...

I classify him as damn dangerous ;) Have fun... --- HARBOR : http://www.kewlstuff.co.za/index.htm The most powerful application server on earth. The only real POJO Application Server.
