Re: favicon when serving non-html
Why would you?
FavIcon is meant as attributes of pages, more specifically pages of whole
sites.
You can potentially have different FavIcons for different parts of your web
site, but that is not common. Resources, which PDF is, have no reason for
having a favourite icon. It would be the same as asking can my GIFs have
favicon. No, they cannot. Nor should they.

Subject: favicon when serving non-html
Hi,
When I serve up, say, a PDF file, how do I control the favicon?
Here's my code:
response.reset();
response.setContentType(IOUtilities.gMIMEType(fn));
response.setHeader(Content-disposition, inline; filename= +
file.getName());
OutputStream outStream = response.getOutputStream();
synchronized(response.getOutputStream()){
outStream.write(IOUtilities.gFile2Bytes(file.getAbsolutePath()));
}
response.flushBuffer();

Re: Windwos Integrated Authentication using AD and Tomcat (no prompt to the users)
Just to make the picture complete, it can also be done with Apache + mod_auth_kerb + mod_jk. It does require some steps and the most tricky one is getting a proper Kerberos Service key from MS ADS. We've done it, so it is not really a big deal. However, people tend to state that TC is as good at serving static content as Apache and that eliminating one link in the server chain reduces complexity. Which is true. And which is why we need a proper Kerberos realm for these setups. Nix.

Re: Right way to close database connection pool
Why exactly would you want connection pool to be closed by TC? I understand your point of view - you have that one web application and it is using the pool and you are seeing something that looks like a leak. Take a look from Tomcat's perspective. It has a JNDI bound resource, DataSource in this case. TC has no way of knowing that that particular resource is being exclusively used by just that one application. It can be used by several applications. So, why close it? On the other hand, even if it knew that the DS is being exclusively used by your web application, which has been undeployed at some point, why should it close (and then re-open) the DS? DataSource pool is managing a pool of connections, it is opening, closing and recycling connections as needed. When the container (TC) goes down, I would expect it to close the entire pool, but I don't see the need for closing it while TC is up and running. Nix.

Re: Tomcat 6.0.18 on Win32 - Enabling Security Manager
I must say that the nature of your questions leaves me with some concern
about the content of your guide...
Hmmm, I wont bite but I will provide a little more information on what I am
doing.
The guide is specifically being written for Tomcat on Windows, which in my
searching of the web there is very few resources available, and even fewer that
provide collated recommendations.
As you may have guessed (and is eluded to in the response below) I am not an
expert at Tomcat or Java however I need to put together a guide that can be
delivered to infrastructure managers whose primary goal is to 'get it working'
without considering security.
So as part of the information security team I have to provide recommendations
to those Infrastructure managers on how to secure the infrastructure (as well
as every other application and piece of infrastructure that is being deployed).
The majority of the guide is focused on management of the Tomcat server. Things
like running tomcat as an unprivileged user (and getting the appropriate
Windows permissions to allow that to work properly), Separation of tomcat
directories from program files, segregation of duties for Wep-app content and
Infrastructure admins, removing or limiting access to default or manager
applications, limiting access to sensitive (or dangerous) Windows files and
folders, etc, etc, etc.
Noble cause.
Note one thing, that has nothing to do with Windows, but Java Security. When
you enable it, almost all activities directed outside JVM, and even some
directed inside it, will require particular permissions. See the supplied
security policy for some details, but I will add one that is always present and
not covered in that file (for obvious reasons): connection to a DB.
If you wish to use any DB server, you will need a TCP/IP connection, via JDBC,
to that DB. I am not counting in in-memory DBs, like HSQL. To make the
connection, or rather to let JDBC driver make the connection, you must add an
appropriate permisssion to your JDBC driver classes. Something like:
grant codeBase file:${catalina.home}/psa-webapps/mydomain.com/myapplication/ {
permission java.net.SocketPermission localhost,resolve;
permission java.net.SocketPermission localhost:3306,connect,resolve;
};
I'm not sure this works, though, just picked it up on Google, but that is how
it generally should look. Though, I'd use class name, not file location for
targeting the JDBC driver.
This applies to all aspects of your application, like web services, RMI, disk
access,...
So, turning secure mode on can require additional work. Not that I consider it
a bad idea, but just have in mind that it is not just adding a couple of
switches. You should tailor security policy for your application's needs. And
it can be a lot of work, plus, it will require testing to see if you've missed
something.

Re: AJP vs HTTP connectors?
Hi all. Jumping in a bit late, but... You have 3 options for plugging TC into Apache's URL space: 1. mod_proxy + mod_proxy_http 2. mod_proxy + mod_proxy_ajp 3. mod_jk Solution 1 is a simple proxy, works like a charm, except for one thing - it WILL NOT give you the identity of authenticated user. So, if you are using Apache for some fancy (or less fancy) authentication, TC will know nothing about it. The connection will be from Apache web server, as far as TC can say. Options 2 and 3 WILL pass the information about authenticated user (if any), so you will be able to issue request.getRemoteUser() and get user identifier, whatever it is. Option 2 is prefered, as of late, for it's setup simplicity, but I'm not sure where it stands in regard to balancing. mod_jk is relatively more complex to setup, but it gives a bit more control. Do you need the control is questionable. I've seen both 2 and 3 work OK. Nix.

JSF and JSTL's forEach which is apparently supported in JSP2.1 (2.0) and
Tomcat 6.
I have the version number in web.xml set to 2.5 and the faces-config.xml
file set to 1.2 (see below).
I checked the version of JARS included in the WAR file and they are :
standard.jar : Implementation-Version: 1.1.2
jstl.jar : Implementation-Version: 1.1.2
jsf-impl.jar : Implementation-Version: 1.2_04-b20-p03
jsf-api.jar : Implementation-Version: 1.2_04-b20-p03
Below are the configuration files included with my WAR. I am using Tomcat
apache-tomcat-6.0.16. I have found some older examples where I got this
working, however I can't see why it doesn't work for me anymore.
Any suggestions on this would really help me out a lot.

Balancing solution which allows graceful partial node migrations
Hi all. This is just a question out of curiousity. Is there a balancer solution that can allow for controlled migration/upgrade of nodes? To explain, suppose you have Apache/mod_jk and you have N Tomcats in balance over that setup, same web application on all of them. Now, suppose you would like to upgrade the application without disrupting the service. Suppose you have fixed a bug. It would be nice if one of the nodes in cluster could be brought out of the cluster, but gracefully. By gracefully I refer to stopping new requests to the node and letting existing requests drain out. When all requests are over, it can be brought down and upgraded. Then it would obviously need to be brought back in. Let us suppose that the new web application is not in semantical inbalanace with the old nodes. Of course, this brings into question what is draining out existing requests? Does that mean open HTTP sessions or just rrunning requests. I suppose, in case of session, we could turn to sticky sessions, right? So, what are your thoughts on the subject? Ever seen something like that in the wild? Or at least in the lab? A balancer that can be reconfigured (almost) online and one that allows for requests to the node being evicted to finish, first. Nix.

First of all, this is entirely client side stuff, so it should not make any

Tomcat related in any way.

Why would you use `src=${imageUrl}` and then use the clumsy

The answer is simple, imageUrl is calculated in the controller/servlet for
each request. com.libris4youDATA_PHOTO_HEIGHT is a constant embedded in
the Java code, where it belongs. And, here is another one: in your example
DATA_PHOTO_HEIGHT is the name of the variable. In my example, I have already
made THAT name a constant in the Java class.

code. It could be that my quest is futile, but I wanted to pursue it and see

not create a Constant object called PHOTO or something. make the

Then you can use the following in your jsp page

width=${PHOTO.WIDTH}/
Alas this is not what I'm looking for.
My desire was to avoid code duplication and I spotted it in the fact that I had
photoHeight (as a String) in two places:
1. in controller, which bound the value under that name
2. in JSPF which used that name in EL

How to write this elegantly in JSP/EL
Hi all.
This is not really TC related, but more JSP and EL question, but I thought I'd
ask.
I would like to have an elegant way of using constants from Java classes in EL.
This is a relatively good illustration of what I am talking about. Take, for
instance, a Spring controller. It has a method where the programmer can bind
objects to model-and-view, which basically binds it to a request or session
scope. It is very similar to a plain Servlet doing request.setAttribute(
name, value ).
public class SomeController extends SimpleFormController {
public static final String DATA_PHOTO_WIDTH = photoWidth;
public static final String DATA_PHOTO_HEIGHT = photoHeight;
...
protected referenceData( ... ) {
...
modelAndView.put( DATA_PHOTO_WIDTH, photoWidth );
modelAndView.put( DATA_PHOTO_HEIGHT, photoHeight );
...
}
...
}
And then in JSPF or JSP:
img src=${imageUrl} alt=Author photo height=${photoHeight}
width=${photoWidth} /
Notice that the EL variable name is the same as that constant. So, I have 2
places to keep in synch. If I wrote that in a scriptlet, it would be correct,
from the point of do not duplicate code:
%= request.getAttribute(
com.libris4you.books.maintenancepanel.AuthorTabController.DATA_PHOTO_WIDTH ) %
Now, how could I do the same in EL?
Something like (tongue in cheek):
width=${=com.libris4you.books.maintenancepanel.AuthorTabController.DATA_PHOTO_WIDTH}
Did I miss something crucial in EL?
Nix.

Re: Defining loggers best approach?
But as Mark's loggers are 'static', don't they have the same
semantics WRT serialization as 'instance transient' ?
Should be. After deserialization, all static fields should be (re-)initialized,
thus, leading to logger being present, class-wide.
If so, Mark's would seem more efficient to me (though I could be
wrong) due to reduced object instantiations.
Static avoids one if per method call.
Indeed, singleton design pattern seams much more efficient with static
initialization, than if (singleton == null) { init() } pattern.

Re: [OT] Re: PUT or POST?
Apparently our fat client can issue either a POST or a PUT request. The client developer has a slight preference for PUT. I must admit to not being familiar with HTTP PUTs - are there any downside to using PUTs (aside from having to override doPut())? I don't think your code will not be any different -- aside from having to override the doPut() method in your servlet. However, the HTTP spec has rules that are most strict when using PUT; you have to respect all of the content-* headers among other things, and are required to return a 501 NOT IMPLEMENTED if you do not support such options. The bottom line is that HTTP PUT appears to have a more robust set of options, but you really should implement them properly. HTTP POST will allow you to be a bit lazier in your implementation. It is also a question of semantics. If the technical side is the same, then let us communicate our intentions clearly. GET - request which will not change the state of the server side (a.k.a. idempotent method). Used for querying server side. POST - request that will change the state of the server side. Used for submitting data to the server side. PUT - request that will create an object on the server side, accessible via the given URL. Used for object upload. DELETE - delete an an object from the server URL space. So, one could argue that POST and PUT have similar semantics. They both send data to the server and expect the state of the server side to change. However, PUT is more oriented to the pre-web app era and more inclined to notions of manipulating static content. POST is more inclined to web applications and to notions of submitting data to be processed. If you expect that crash data will create an object, real or virtual, that will be accessible via the URL you will provide for PUT method, then PUT seams like a good choice. If you are submitting data and some other object may come to exist (like crash report) or not, as a result of that data submission, then POST is a more proper choice.

I set mod_jk to log level debug, and saw it was telling apache 2No.Host.matches.server.name. This simply means that Apache is accepting a request for one Virtual Host an that host is not configured in TC. This issue can be as trivial as not defining the actual hostname as a Host element in your TC server.xml Read TC docs, pay attention to the Host tag. It is used to define as many virtual hosts as you like. The thing is, the virtual host in Apache, *which is going to forward requests to TC*, MUST exist in TC, as well. It is as simple as that.

Re: Intermediate write in JSP
I had a similar issue in the past that I overcome by having the servlet start a separate thread that was producing the report, And a jsp page refreshing every 10 seconds or so checking for completion. That is, of course, the asynchronous application design. Sometimes it is necessary, but it does bring a question. What is being so slow? Sending the amount of data you're sending is not slower than it can be. My guess is that DB is taking a rather long time to complete the query. I would not blame the network, because the Net connection between DB and TC should be at least as fast as the one between TC and your client. So, the original poster might wanna take a look at the DB for speeding it up. It might not be possible, though.

Re: Flash and Javascript
I currently have a Flash file which uses the ExternalInterface.call function to call some JavaScript functions I have on a JSP page running in Jetspeed 2. When I publish the file to an HTML in Flash and just view it on my computer it works great, but I have tried making a JSP page out of it and putting it up on my server and when I am clicking the buttons that should be calling these functions, nothing is happening. I really do not know if it is a Flash problem or a Tomcat problem, but I haven't been able to find anything on Flash messageboards about it. [ ANSWER ] OK, this is not strictly a proper place, but I can think of no other, so here goes. Your question is a bit vague. If I understand correctly, you have one JSP page, which could even be a plain HTML, as far as your problem goes. That page embeds a Flash, which calls a JavaScript, also present on thet page. This all is a client-side stuff, none of it is taking place on the server, right? If this is the case, no wonder nobody responded :-) This looks like a HTML problem, take a look at the source of the page and figure out what's wrong. From your description, it should be tottaly irrelevant whether the page is HTML or JSP (unless that JSP is doing something on the server-side, like querying DB). It should also be totally irrelevant if it is on your local machine or an the web server - in case of HTML. JSP would require JSP engine, like Jetty or Tomcat. My advice to you is, make it work in pure HTML first, both on your local machine and on any web server (to rule out wrong links and similar gotchas). Then embody it in a JSP page.

Re: PHP Servlet Fails in Tomcat 5.5.15-SOLVED
Hi all. Just one opinion, if it hasn't been said before. Do not mix Java and PHP. PHP is inherently thread un-safe. Basically the PHP code itself is, AFAIK, OK (thread safe), but all those myriads of 3rd-party libraries providing needed functionality to the myriads of PHP extensions can, and some are thread un-safe. In case you haven't noticed, most decent Linux distros disable multi-threaded MPMs in Apache, if you enable PHP in them. Well, if Apache feels unsafe with PHP around, how should you feel in Tomcat? I can understand why you would want to run PHP, a lot of freeware projects out there were written in PHP. Or, should I be more precise, in PHP+MySQL glued together. Perhaps you cannot afford to rewrite it all. But sometimes, it is worth it. Decision remains yours, but I would run PHP separately from TC, if at all possible. Nix. __ Do You Yahoo!? Tired of spam?

It is definitely generated in the JNI method, so you'd have to look in there. I then altered the servlet class to include some debugging info just prior to its invocation of the send method: send(request.getMethod(), request.getQueryString(), request.getRequestURI(), contextPath, request.getContentType(), request.getContentLength(), request.getRemoteUser(), display_source_mode ); Here is the result: request.getMethod() = GET request.getQueryString()= null request.getRequestURI()= /test.php contextPath = /home/gsl/tomcat/apache-tomcat-5.5.15/webapps/ROOT/test.php request.getContentType() = null request.getContentLength()= -1 request.getRemoteUser()= null display_source_mode = false This looks fine.

The error would have been much different, in case of a signature mismatch. Alternatively, does anyone have any further ideas on what I could do to debug this further? A few other individuals posted this null IOException on the net, but no resolution was provided. Being such a generic error, their problem might not even be related to what I am experiencing. Well,... As I have said above, the exception is thrown in the native method, so you could go into the source of that method and see where it could throw an exception.

Re: Tomcat - Hibernate
--- Giorgio Clavelli [EMAIL PROTECTED] wrote:
Hi,
I'm not an exper at all, but I try to put my 2 cents.
The fact that your app can connect successfully after the server restart,
suggests that you should have your app's context.xml (or whatever it is
called) not in the server.xml but in the correct location inside your app
directories. I seem to have read, the correct location being under the
META-INF directory and that Tomcat tries first to look for context in this
dir and then use that one under server.xml.
I hope expert user, will comfirm in one way or the other this understanding
of your problem.
As of TC 5.0 the prefered way of configuring a context (web application) is to
use a XML context fragment file. That file will either be placed in
${CATALINA_HOME}/conf/${HOSTNAME}/${CONTEXT_NAME}.xml, if you're deploying from
a directory or in ./META-INF/${CONTEXT_NAME}.xml, if it is a WAR file.
That way, deploying of an app can be free from editing the server.xml.
As for the original problem, that is NOT it. The fact that TC's restart picks
up everything suggests that the config is OK. Or at least relatively OK. I
think that TC will create a XML fragment for the app and it could be that
*that* fragment is interfering with the deployment process.
Since I can see nothing wrong with the config, I would advise the original
poster to go the correct route. Create the config fragment, pack it into your
WAR, clean up server.xml and try to deploy/undeploy/redeploy. It will have no
effect on TC 4.x, if you're warried that you might be forced to use it some
day, TC4 ignores that file (one question to the authoritative guys: will that
dir be accessable? - a potential security hole).

You would have to override some of Struts functionality, locate where it loads config files and add a hook for decryption. Not a trivial task, but should not be impossible. The biggest issue with this is that by doing so, you're creating your own Struts port/branch and you would have to maintain it plus all upgrades. Switching over to a newer release of Struts would require you to build your Struts again, with the your changes. Not something I would recomend. And again, it is not impossible to crack. In my oppinion, it is not worth the time, unless your securtity requirements are really high. But then, the machine's security is probably more important than encrypting config files.

Re: css and images (stupid question?)

Hi all;
playing around with tomcat in order to both learn using the package and
create a small web site there, I'm currently left with a problem which,
though probably being small (and not really related to tomcat), keeps
bugging me:
I'm trying to do the visual stuff of my jsp using a css style file,
which is good, so far. Within the css file, I'm using images for
backgrounds etc like that:
background: #fff url(/images/bg_header_blau.jpg) no-repeat top left;
My problem, right now, is where to put the images within the web
application so they're actually found when displaying the page.
Initially, I created a folder images within my web application and
referred to the images using url(images/...) with relative path names,
which didn't work. Also tried to place the images folder inside
$CATALINA_HOME/webapps and then using absolute image urls (/image/...),
which also didn't work.
So, where's the magic? I've always been through some tougher moments
with css and images while dynamically generating content, but right now
I feel really helpless about that. Can someone enlighten me?
Well, your basic problem is that relative paths will not work, since
pages can be in different directories. Absolute path has one problem,
your application can be deployed under different paths. That problem is
easy to solve, HttpServletRequest.getContextPath() will give you the
deployment path. Just paste it on your desired CSS location, like this:
css.jsp
---
...
background: #fff url(%= request.getContextPath() %/images/bg_header_blau.jpg)
no-repeat top left;
or, if you're using JSP 2.0
background: #fff url(${request.contextPath}/images/bg_header_blau.jpg)
no-repeat top left;
...

Re: Use of JSF view in welcome file list
Tim Dean wrote: Hello, I am trying to configure a welcome file list in my Tomcat-deployed web app so that a Java Server Faces (JSF) view is used as the welcome file. My web.xml file contains the following: welcome-file-list welcome-filemain.faces/welcome-file /welcome-file-list As well as the following JSF servlet configurations: servlet servlet-nameFacesServlet/servlet-name servlet-classjavax.faces.webapp.FacesServlet/servlet-class /servlet servlet-mapping servlet-nameFacesServlet/servlet-name url-pattern*.faces/url-pattern /servlet-mapping I have been unable to get this working no matter what I have tried. Whenever I request a directory within the web application's context, Tomcat shows a directory listing instead of the JSF view I've identified in the welcome file list. Well, the problem is in the fact that a list of welcome files is just that, a list of FILES. So, when a URL is requested which is a directory, a list of welcome files will be looked up in that dir, in the given order. What you gave was an incomplete Servlet URL mapping and that simply will not do for a welcome file list. Perhaps you could try to setup a different mapping, like servlet-mapping servlet-nameFacesServlet/servlet-name url-pattern*//url-pattern /servlet-mapping This might clash with directory URL mapping, which should be more internal to TC. Or is it handled by the Default Servlet? In that case, it would be OK, since this mapping is less general than *. Also, note that FacesServlet might not handle this properly, expecting the URL to point to some file/path/identifier (I know how Struts would see it...) and this might require additional setup in JSF config file (mapping that URL to appropriate component).

Re: Unix socket communications on Tomcat 5.5
Bill Barker wrote: Currently mod_jk doesn't support unix sockets (ditto for mod_proxy_ajp :). To use unix sockets currently, you must use (the currently unsupported) mod_jk2. However, there is some intial support for them in the new APR Connector. It's not complete (and so not usable :), but it's possible that some future version of mod_jk/Tomcat will support this. I'm sad to hear that. The story of mod_jk/mod_jk2 succession was that all nifty features of mod_jk2 will be ported to mod_jk. I must say I have UNIX socket on mod_jk2 in a Mandrake 9.1 Linux Apache 2.0, TC 4.1.24 and it is working without a glitch. I haven't stress tested it, though. Can anyone comment on the need for a UNIX socket? The basic idea was that UNIX socket is faster, but with the advance of kernels, is net socket communication that burdening? OK, on a busy server, it could profitable to lay off as much traffic off the network stack, as possible. Can someone give insight? Currently, I have mod_jk2 in a good working condition and I have access to both mod_jk2 and mod_jk. I'm not about to switch to mod_jk, just for switching's sake. On the other hand, I'm not going to stick to obsoleted softrware, either. So, I'm waiting (patiently) for expert opinion.

Re: Unix socket communications on Tomcat 5.5

I've been trying to find some decent documentation on setting up
Tomcat to communicate with mod_jk2 and Apache over unix sockets. So
far what I've found suggests I only need to alter jk2.properties with
details of the socket, and workers2.properties with the same details.
I've done this and restarted Tomcat and it still appears to be
creating the TCP/IP socket on port 8009, but not creating any unix
socket file.
Has anyone got a working Tomcat 5.5 mod_jk2 configuration using Unix
sockets I'd love to know what you did to set it up.
Hmm, well, there are several things to consider.
First, in order to use UNIX socket, you need to have and link JNI
library specially built for your OS. UNIX sockets are not a part of Java
world and to use them you need JNI library which is a part of mod_jk2
source distribution. You'll also need Apache-Dev RPMs or
libapr+libaprutil, if I recall correctly.
Then you need something like this (this is from my 4.1.24)
