Re: Windows Authentication: Issue 49318 vs 47679
On Mon, Mar 28, 2011 at 7:26 AM, Stefan Mayr ste...@mayr-stefan.de wrote: Hello everybody, as many others before we wanted to do single-sign-on for intranet web applications using integrated windows authentication (negotiate because IE sometimes tries NTLM instead of using plain kerberos - breaking all our kerberos-only experiments). We thought that IIS would be the best choice for integrated windows authentication and we could pass the user via AJP (using mod_jk) to our tomcat instances. Our setup: - Windows 2008 R2 using IIS 7.5 (64bit) - mod_jk 1.2.31 - Oracle Java 1.6 U24 - Tomcat 6.0.32 At first glance using tomcatAuthentication=false worked as expected. We got the remote user and started deploying an application. End of happiness - the application complained about a missing user-agent. That header was not passed to tomcat when authentication was enabled on IIS. Some research revealed Bug 47679 - Not all headers get passed to Tomcat server from isapi_redirect.dll (https://issues.apache.org/bugzilla/show_bug.cgi?id=47679) Today I've found Bug 49318 - add a Negotiate (Kerberos/NTLM) authenticator / integrate Waffle (https://issues.apache.org/bugzilla/show_bug.cgi?id=49318). The last comment links a new Windows Authentication How-To from Mark Thomas. Looks like we have already tried almost all proposed solutions: - IIS + mod_jk: tried but stuck in Bug 47679. Also tried ARR to pass the user name as a request header from IIS to Tomcat without success - Apache mod_ntlm: used it and we replaced it by the much more stable mod_auth_ntlm_winbind. NTLMv1 is also disabled on Windows 7 (default) - Apache mod_auth_ntlm: in heavy use but stuck to Apache 2.0 and 32bit plattform - we couldn't get stability problems solved on Apache 2.2 and 64bit Linux. No ongoing development. - Apache mod_auth_sspi: till now in internal use for a very small project (works just fine), not sure about the future. Although there seems to be some new activity on 1.0.5 beta - Waffle: found it on thursday and it is on my our todo-list for testing it next week Any chances to get Bug 47679 solved?

Re: Tomcat 7 Startup Problems
Long explanation: 1) the Windows installer, for some unfathomable reason, does not contain all the files. The 64-bit zip file does. 2) a standard java JVM does not have the plumbing to run well as a Windows Service (for example, it does not react to Windows Service Events). That's why some smart people created a service wrapper which does have such plumbing, and this wrapper in turn will run the JVM which runs tomcat. This wrapper is what you get as tomcat7.exe. 3) this wrapper takes its parameters from the Windows registry (for example, which JVM to run). Another Windows program, distributed as tomcat7w.exe, is the GUI editor which allows to view/modify these parameters. Normally, all this should be set up properly by the tomcat exe installer. But it looks like in your case, something did not happen correctly. Under Windows 7, it may be because you did not get rid of UAC, or did not run the installer as an administrator, or who knows what else.

[Cluster] context question
Hi,
/Tomcat 7.0.10, OSX 10.6.5, jk 1.2.31, and httpd 2.2.17/
Without any explicit parameters in server.xml, just by setting the jvmRoute
attribute in the Engine element and enabling Clustering, session failover
worked if I shut down one or the other tomcat instance or the one httpd that
was not the reverse proxy.
However when I just stopped the example webapp in one tomcat, the session did
not failover and I received a 404 http error instead of the expected session
page from the other tomcat.
Based upon the instructions found in the book:
http://proquest.safaribooksonline.com/9780596101060/tomcat_6_clustering_implementation?sessionid=reader=htmlimagepage=
explicitely:

You'll also need to add distributed=true to the webapp's Context element.
If there is no Context element declared for it anywhere, you will need to
create one. You can create one by making a
newCATALINA_HOME/conf/[EngineName]/[HostName]/examples.xml context XML fragment
file or by adding one to server.xml.
nyassz
my thought was that the ReplicatedContect was not initiated. Well, I already
learned that I should not add any context into server.xml and there is nothing
in the
bml0066:local administrator$ ls -l tomcat1/conf/Catalina/localhost/
bml0066:local administrator$
directory, so I created a META-INF directory inside the examples directory and
placed a context.xml there with the following content:
bml0066:local administrator$ cat tomcat1/webapps/examples/META-INF/context.xml
?xml version=1.0 encoding=UTF-8?
Context className=org.apache.catalina.ha.context.ReplicatedContext
distributed=true
/Context
I did it on both tomcats and bounced them. Now when I look the log, I see the
following warning just after restart:

So the first question is, should I use the distributed=true property here ?
Is the book right ? I think it is from 2007. I already have the
distributable/ tag in the webapp's web.xml.
The second question is what to do to avoid the 404 message and fail the session
over instead of it, when I just stop the webapp on the tomcat instance? By
default I am using sticky sessions.

Similar server.xml exists for the other machine bml0065 only the jvmRoute and
the ports are different.
Here is a snippet showing the distributable tag in web.xml in the WEB-INF
directory of the examples web app:
nyissz
!--Temporarily the distributable tag goes here --
!--It should be in the given webapp's web.xml --

/web-app
nyassz
I created an examples.xml in the $CATALINA_BASE/conf/Catalina/localhost
directory on both machines and the content of that file is this:
nyissz
bml0066:local administrator$ cat tomcat1/conf/Catalina/localhost/examples.xml
?xml version=1.0 encoding=UTF-8?
Context className=org.apache.catalina.ha.context.ReplicatedContext/
nyassz
Unfortunately if I have just Context
org.apache.catalina.ha.context.ReplicatedContext/ there then I receive these
type of messages:

I did a little test. I opened the URL
http://bml0065.yalepath.org/tc/examples/servlets/servlet/SessionExample on my
machine /bml0041/. The reverse proxy sent the request to itself, then jk sent
it to the tomcat3 instance on the same machine. I can see in the log of
bml0065:

Looking at the tomcat log on the other machine - bml0066 - I can see that the
session is replicated:
nyissz

Then I stop the examples application on the bml0065 machine running the tomcat3
instance.

OT: Versioning in Javascript Files
I'm looking for ideas on how other people are doing versioning in Javascript files. I'm hitting issues if I change my files in an incompatible way, or I upgrade files. For example, if I upgrade from DOJO 1.5 to DOJO 1.6, the user's browsers are not always refreshing the DOJO files, and things don't work. Similarly, if I update a javascript function to take additional arguments, then the browser using the old version throws an error. I've spent a lot of time in the past few days telling users to click on the refresh button of their browser and I'm pretty sick of it. I've thought of versioning my whole scripts directory. IOW, if my app version is 3.4.9, make the scripts directory scripts-3.4.9 to force the browser to get files from the new location. This is kind of a pain for version control reasons but otherwise it's OK. I'm really looking for ideas on how other web developers are handling this problem. -- George Sexton MH Software, Inc. 303 438-9585 www.mhsoftware.com - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

and i try to keep many connections open and for each client connected
return a string each time than other client press go() but the

execute the event.close(); and close my connection
how can i send data to the clients without close the connection or

Two Tomcat 7.0.11 installations in the same Linux instance, running both on port 80, without conflicts?
Hi, I have a Linux instance, on top of which I'm running Tomcat 7.0.11. This Tomcat installation is running two websites, using host virtualization. These websites run both using port 80 and the SSL port. For several reasons, I usually have to restart this Tomcat installation, which takes 30 seconds in the best case scenario. So every time I do that, all the apps are down while it happens. I have a new project, for a web service that must be running all the time. It should never be offline, and if it does, my clients will leave me, so I can not run this app in the same Tomcat installation. I'm considering a parallel Tomcat installation in the same Linux VPS, both running at the same time. I perfectly know that it can be done, but how do I do with the port conflict? How can both Tomcat installations run using the same port 80? Is there a way to configure Linux so Tomcat A will serve some domains AND IP addresses, and Tomcat B will server other domains AND IP addresses? Thanks in advance!
