What does your configuration look like? Are you using Resource in

RE: Destroying resources created with a custom ObjectFactory
Hi,
There seems to be no simple way to destroy jndi resources in tomcat, somebody
had a similar problem here
(http://fogbugz.atomikos.com/default.asp?community.6.2101.7) and was advised to
use tomcat org.apache.catalina.Lifecycle* classes.
What I had first in mind was to register a NamespaceChangeListener into the
context passed to the getObjectInstance() method but, apparently, it does not
implement javax.naming.event.EventContext. This is what I wanted to do:
http://pastebin.com/W7dCafPS (on pastebin to keep the formating).
Is there another (simple) way to destroy my jndi resources?
Thanks,

For some reason, Java code remains tucked-away in the tcnative project but it is no longer used (or shouldn't be). Tomcat includes in its standard distribution everything you need to use tcnative. Did you manually compile the Java portion of tcnative? If so, please remove whatever JAR file you produced from that procedure and re-run your tests. Looks like that in latest version of native library , the addWithTimeout function is missing. The C counterpart indeed is present in the native library. Does it make sense to copy the Poll.java from the tomcat src to native library and build the native library??

Does that mean that Tomcat treats WIA similar to HTTP BASIC (or maybe DIGEST) unless you've approved a particular domain/host? That's interesting. Can you just enter anything you'd like?

That certainly sounds nice: the Microsoft Windows crowd doesn't have to authenticate (explicitly, that is... their credentials are that they are currently logged-into a machine on the network) but everyone else can also get in. If tomcat is setup to work with SPNEGO authentication, then when a new session requires authentication, the server asks the client for a kerberos token. Under IE this will be passed silently. Under FF if you have configured the network.automatic-ntlm-auth.trusted-uris to the url of the server, this will be passed silently. If you setup your *nix machines to login to active directory they will have a kerberos token. If you also make the FF setting change, they to will then be able to silently login by sending through the kerberos token. I think as you configure the server, you can specify what to do it SPNEGO fails. I guess one option would be to fail back to http basic. If you didn't want to get the *nix machines to login to active directory, then I guess that would be a way to go.

Re: Embedded Tomcat how to use addContext for docBase
2013/1/29 Jimmy Johnson eclectic.sou...@gmail.com:
System: Mac OS X 10.8
Tomcat Version: 7.0.30
Language: Java
I'm trying to set up the context in an embedded Tomcat instance to serve
files from a local directory not within the deployed folder.
In the standard server.xml when using the standard Tomcat configuration I
have this:
Context docBase=/MyWebApp/images path=/tmp/images/
reloadable=false/
and it works great.
I have tried different variations on the following tomcat embedded call
without success:
tomcat.addContext(tomcat.getHost(), /MyWebApp/images,
/documents/images/);
I also tried:
tomcat.addContext(/MyWebApp/images, /documents/images/);
It seems that Tomcat does see the external docBase folder I have specified
because if I specify a path that doesn't exist it complains. It also see's
the context mapping because hitting the /MyWebApp/images filters out the
request before it hits the spring security filters I have in place and
reports a 404 file not found.
I am planning on looking at the source this evening and seeing if I can
track down the file path it is looking at, but I thought someone here might
know of a solution.
It looks like this grails question was along the same lines:
http://stackoverflow.com/questions/8332851/grails-add-context-to-embedded-tomcat-in-development
But im not using grails.
Here is the full startup code I am using:
package launch;
import java.io.File;
import org.apache.catalina.startup.Tomcat;
public class Main {
public static void main(String[] args) throws Exception {
String webappDirLocation = /src/main/webapp/;
Tomcat tomcat = new Tomcat();
//The port that we should run on can be set into an environment variable
//Look for that variable and default to 8080 if it isn't there.
String webPort = System.getenv(PORT);
if(webPort == null || webPort.isEmpty()) {
webPort = 8080;
}
tomcat.setPort(Integer.valueOf(webPort));
tomcat.addWebapp(/MyWebApp, new
File(webappDirLocation).getAbsolutePath());
tomcat.addContext(/MyWebApp/images, /tmp/images/);
The above two lines. You already know the addWebapp method, so why
are you trying to use addContext?
tomcat.start();
tomcat.getServer().await();
}
}

Re: Embedded Tomcat how to use addContext for docBase
Ah, Okay, so I should use the addWebapp method to add a path to an external
folder?
e.g tomcat.addWebapp(/MyWebApp/images, /tmp/images);
Thanks,
Jimmy

2013/1/29 Jimmy Johnson eclectic.sou...@gmail.com:
System: Mac OS X 10.8
Tomcat Version: 7.0.30
Language: Java
I'm trying to set up the context in an embedded Tomcat instance to serve
files from a local directory not within the deployed folder.
In the standard server.xml when using the standard Tomcat configuration I
have this:
Context docBase=/MyWebApp/images path=/tmp/images/
reloadable=false/
and it works great.
I have tried different variations on the following tomcat embedded call
without success:
tomcat.addContext(tomcat.getHost(), /MyWebApp/images,
/documents/images/);
I also tried:
tomcat.addContext(/MyWebApp/images, /documents/images/);
It seems that Tomcat does see the external docBase folder I have
specified
because if I specify a path that doesn't exist it complains. It also
see's
the context mapping because hitting the /MyWebApp/images filters out
the
request before it hits the spring security filters I have in place and
reports a 404 file not found.
I am planning on looking at the source this evening and seeing if I can
track down the file path it is looking at, but I thought someone here
might
know of a solution.
It looks like this grails question was along the same lines:
http://stackoverflow.com/questions/8332851/grails-add-context-to-embedded-tomcat-in-development
But im not using grails.
Here is the full startup code I am using:
package launch;
import java.io.File;
import org.apache.catalina.startup.Tomcat;
public class Main {
public static void main(String[] args) throws Exception {
String webappDirLocation = /src/main/webapp/;
Tomcat tomcat = new Tomcat();
//The port that we should run on can be set into an environment variable
//Look for that variable and default to 8080 if it isn't there.
String webPort = System.getenv(PORT);
if(webPort == null || webPort.isEmpty()) {
webPort = 8080;
}
tomcat.setPort(Integer.valueOf(webPort));
tomcat.addWebapp(/MyWebApp, new
File(webappDirLocation).getAbsolutePath());
tomcat.addContext(/MyWebApp/images, /tmp/images/);
The above two lines. You already know the addWebapp method, so why
are you trying to use addContext?
tomcat.start();
tomcat.getServer().await();
}
}

Without looking at the Atmosphere code, it's really impossible to tell. Understood about TomEE not supported on this list. Prior to using latest Atmosphere version (1.0.9) along with latest version of TomEE, I reached out to Jeanfrancois, and he confirmed that Atmosphere 1.0.10 is targeted for PrimeFaces Push users (like myself), and from what I understand, 1.0.9 fixed a simple software/typo mistake in 1.0.8, and I'm assuming that 1.0.9 should not be used to replace 1.0.8 by PrimeFaces Push users like myself. for now, i have reverted to Atmosphere 1.0.6, which was the recommended (and most applicable/appropriate version), weeks ago, to use with my PrimeFaces web app. I informed the tomee list that I will monitor this behavior for the meanwhile, and I'm looking forward to using/testing Atmosphere 1.0.10 when it is released.

Re: LDAP on TOMCAT 7.0.30
chris derham wrote: Does that mean that Tomcat treats WIA similar to HTTP BASIC (or maybe DIGEST) unless you've approved a particular domain/host? That's interesting. Can you just enter anything you'd like? For instance, can I authenticate to a server that is expecting WIA from a Linux workstation just by entering my domain credentials into the dialog? That certainly sounds nice: the Microsoft Windows crowd doesn't have to authenticate (explicitly, that is... their credentials are that they are currently logged-into a machine on the network) but everyone else can also get in. If tomcat is setup to work with SPNEGO authentication, then when a new session requires authentication, the server asks the client for a kerberos token. Under IE this will be passed silently. Under FF if you have configured the network.automatic-ntlm-auth.trusted-uris to the url of the server, this will be passed silently. If you setup your *nix machines to login to active directory they will have a kerberos token. If you also make the FF setting change, they to will then be able to silently login by sending through the kerberos token. I think as you configure the server, you can specify what to do it SPNEGO fails. I guess one option would be to fail back to http basic. If you didn't want to get the *nix machines to login to active directory, then I guess that would be a way to go. Guess that it all depends on the security requirements I believe that you both are close to the correct understanding, but that it helps to clearly distinguish the various parts of the process, and be very clear about the terminology (which unfortunately is quite confusing, because many people are using terms like SPNEGO, GSSAPI, Active Directory authentication, NTLM, Windows Integrated Authentication etc. all over the place without .. really knowing precisely what they are talking about). The first few paragraphs here : http://en.wikipedia.org/wiki/SPNEGO explain what SPNEGO is, and that SPNEGO in itself is not an authentication mechanism. It is kind of the preliminary layer which allow a browser and a server to negociate which real authentication mechanism they both support and are going to use in the real authentication which happens next. And what happens next can be based on /either/ Kerberos or NTLM (or Basic for that matter), which are different mechanisms. I know little about Kerberos, but in the context of workstations belonging to a Windows Domain environment, running web-based applications and desiring to use a Windows-based form of authentication and SSO for these web-based applications, most organisations which I have come in contact with until now (including some large multinational ones) do not use Kerberos as an authentication mechanism; most of them still use NTLM (v2 nowadays). In summary and approximately, this is how WIA/NTLM works : - the browser picks up the user-id which the user used to login onto his Windows workstation when he started Windows - the browser transmits this user-id to the webserver it is communicating with, in some form (it actually takes several coded message exchanges for that) - the webserver verifies this user-id with a back-end Windows Domain Controller - the Windows Domain Controller in turn uses a back-end to check this user-id (this back-end being generally an Active Directory server) - if all of the above works as it should, the webserver accepts this user-id, and makes it available to the web applications that run on this webserver on behalf of that browser, for as long as this browser-server connection persists. (and if a new connection is established, the cycle is repeated) Now as long as the workstation runs Windows, the browser is IE, the webserver is IIS, both the workstation and the webserver are in the same intranet, the IIS webserver has access to a Windows Domain Controller, the user-id is valid etc.. then all of this happens automatically behind the scenes and without the user noticing anything. And if any of these conditions is not true, then you will need to put together alternative pieces of the puzzle to make Windows Integrated Authentication work. The good news is that in most cases these pieces exist. The bad news is that you really need to know where to find the needed pieces, how to set them up, and to know that sometimes the behaviour is a bit different from the basic one above. (Such as the fact that FF by default displays a dialog, where IE does not; and that this FF dialog looks just like a Basic Authentication dialog, but it isn't. The authentication taking place is still NTLM, not Basic; but the popup looks the same). (And just to make things a bit more confusing : in about 50% of the cases that I have come across - either as a conscious decision or as an oversight of the domain admins, if NTLM fails then Basic authentication will take place, both in IE and in FF, and provided the user enters the correct user-id and password, the
Scenario with Tomcat cluster session management
As usual, I am always working with Tomcat to tweak every ounce of oomph out of it and I ran across this scenario in my configuration trials. At present, I have a small 3 server tomcat cluster running 7.0.30 64-bit on CentOS, and jdk6. I want to move the project from having to use kill -9 (for session persistence) during an update and manual intervention, to automated parallel deployment's and war farming. From the testing I have done, if I use the manager to undeploy and then redeploy the context, it seems to call destroySession on all the sessions across the cluster, not just the node that is being worked on. Is this correct or am I missing something? Is there presently a way to undeploy a context WITHOUT tomcat destroying the sessions and not use kill -9? IMO, using kill -9 seems a bit hacky. - Josh
