Fwd: Tomcat Thread Log

[Mukundaraman Valakumaresan]

Hi

I have deployed an application in Apache tomcat 7.59.

When I copy the war to webapps folder and start tomcat. Tomcat hangs and I
coudln't see the admin screen as well for the first 30 minutes. Without
this war, tomcat starts fine shows the admin screen immediately.

Through google, I check a posts, which asked me to take a thread dump. I
use Sprint, Hibernate and Mysql. From the thread dump, I could see that and
could also see that the problem with the connectivity to MySQL.

But I am not sure where exactly the problem lies and what needs to be
fixed. Any help is appreciated!! Thanks

RE: Rendering JSP files through Apache

[Leggio, Andrew]

This contains both HTML and JSP.  I would like the HTML to be handled through 
Apache and JSP pages to be handled by TOMCAT.  How do I accomplish this?

This is a Linux environment with Apache version 2.4.6 and Tomcat version 7.

Thanks

That is a funny way of putting it.
What the above does - if everything else is installed and configured correctly 
- is proxying *all* HTTP requests originally directed to Apache httpd 
(including requests for any JSP page), toward a Tomcat supposedly running on 
the same host, and supposedly listening on port 8009.
Now whether this is actually what is happening or not, is anyone's guess so far.
Chances are that this is not happening though, since otherwise you probably 
would not be asking what's wrong.

The question is also : if you are going to proxy all requests from Apache httpd 
to Tomcat anyway, then why do you think that you need Apache httpd ?

External xml problem on Tomcat 6.0.41

[Claudio Weiler]

Hi,

I use a Debian Squeeze distro, with official Tomcat releases. Recently I
update to Tomcat 6.0.41 and a (not modified) application stopped to load.

I dig and found that on Tomcat 6.0.40 the context attribute
"xmlBlockExternal" was changed default value from false to true, then I
modified this attribute in context.xml.

Now, the application do not work, with the exception:

This stacktrace leads me to "fragment scanner" that is exactly what broke
my app on first place. What I use is a xml injection in web.xml as follow:

and:
&certisign;

So, I tested to remove this reference and place the fragment inside web.xml
and this solved the exception and the application back to work.

I searched more infos but none so far. So my questions:

1. What additional modification on Tomcat could be the reason to a working
config stops to work?

2. There is any other context attribute (that I

That's ROOT (case sensitive), also known as the default webapp.

That's not correct - you need to rename your .war file to ROOT.war and place it 
in the webapps directory.  You should end up with just this:

/opt/apache-tomcat-8-perfs/webapps/ROOT.war

Andrew, you are really not providing enough information for anyone to be able 
to help.
Your inline image did not make it to the forum, so we have really no idea what result you 
are trying to show us.
Nor do we know if your Apache httpd configuration is correct.  The configuration lines 
above are not all that you need to do in order to properly load and run the mod_proxy_ajp 
connector module in Apache httpd.
I don't know exactly on which kind of OS platform you are running this, but it kinda looks 
like RedHat or similar.  For a start, as user root, try entering the command "a2enmod" and 
paste here what it displays.

Also tell us what is the content of the Tomcat webapps/ROOT/ directory.

I have the following being used in my conf file:

RE: Configure Tomcat 7 using Apache 2.4.6

Andy,
Thank you for responding.  I changed the mod_proxy_ajp.c to 
mod_proxy_ajp.so which is the module that is being loaded.  Now my html pages 
are rendering fine; however, when I go the jsp pages it's not even putting an 
entry in the tomcat access log.
 Any ideas?

Did you actually load the mod_proxy_ajp module?
Given the directory structure of the configuration files you're likely using a 
distribution bundled apache httpd.  Given that you'd probably get a bit more 
help from the resources for that distribution.  But it's most likely that you 
need to ensure that the module is loaded.

What is the stack trace for TaskQuery.take()? I've never heard of
"TaskQuery"; is that some component you wrote yourselves?

You are using the default protocol ("HTTP/1.1") which will auto-select
the implementation based upon whether APR/native is available or not.
Can you tell us which connector is actually being used?

Did you actually load the mod_proxy_ajp module?
Given the directory structure of the configuration files you're likely 
using a distribution bundled apache httpd.  Given that you'd probably 
get a bit more help from the resources for that distribution.  But it's 
most likely that you need to ensure that the module is loaded.

1. Use the BackupManager rather than the DeltaManager. It also scales
better.

Re: Multiple login/home pages within a tomcat app

[Neill Lima]

Andre,

Excellent reply given the context.

I would add the following:

Given a webapp paradigm why would you need two different login pages to
different resources? Usually what is done is change what the logged user
sees/is able to see. For example:

Scenario 1:

WHEN a administrator logs in to the app XYZ /login URL
THEN the basic option menu is displayed
AND the "Manage users" option is displayed.

WHEN a administrator goes to app XYZ /manage-users URL
THEN "Manage users" page is dislayed

Scenario 2:

WHEN a regular user logs in to the app XYZ /login URL
WHEN the basic option menu is displayed
AND the "Manage users" option is hidden.

WHEN a regular user goes to app XYZ /manage-users URL
THEN "Access not allowed" page is displayed

Of course there is a bit of servlet and security under hood, but I just
wanted to show how the "ACL" would change based on the user-role, not the
URL in question.

Hello Guys,

Hi.
Since you claim to be a newbie at this, I'll try to provide a "learning answer".

1) the simple answer to your question would be : no (or at least not when using the 
standard built-in authentication mechanisms).
But do not be too disappointed, because a more complete answer might be "perhaps, but it 
depends on the circumstances and on what you want to achieve exactly".


2) a basic and generic explanation of how WWW authentication works :

a) the browser sends a request to the server, for some server resource (e.g. a specific 
HTML page)
b) the server receives this request, and checks in its configuration, if this resource is 
"protected" and requires some form of authentication/permission.

If not, the server returns the requested page and things stop here.
So the rest below, is in the case where the requested resource is protected.
c) the server then checks if the browser request already contained some form of user 
authentication. (This can be various things, and i will not elaborate at this stage).
If the request contained such an authentication, the server verifies it, and if it is ok, 
the server returns the requested resource (e.g. the desired HTML page), and things again 
stop here.
d) if the request did not contain ditto valid authentication, instead of returning the 
requested resource, the server sends back something, to let the browser/user know that an 
authentication is required.  This can also be various things, and I will again not 
elaborate, but let's suppose that in your case what is returned is a login page.
e) the user/browser gets and sees the login page.  The user fills it in, with user-id and 
password, and sends this info back to the server.
f) the server verifies the submitted user-id/password, and if it is ok, returns the 
desired resource to the browser/user.  At the same time as sending that requested page, 
the server also sends some "token" to the browser (for example a cookie), containing the 
proof that this browser/user is now authenticated.
g) for subsequent requests to the same server, the browser now always sends this token 
along with the next requests.  This will fulfill the check that happens at (c) above, so 
that for these following requests, the server will be happy and will return the requested 
pages, without asking again for authentication.


There are many variations possible in the details, but in rough terms, all forms of WWW 
authentication follow more or less the above scheme.


Your question relates to step (d) above.
The server has to return a login page, but you say that it should return a specific one 
among several possible login pages.

The question thus becomes : how does the server know /which/ login page to 
return ?
(The user is not yet known/authenticated, so the server cannot use the user-id or any 
other user-related information in order to choose.)

So what other criteria can the server use then ?

Possibilities would be :
- the login page changes depending on the time of day (that's kind of unusual, but it is 
just to illustrate the point)

- the login page changes depending on the user's IP address
- the login page changes depending on something else which the browser sends along with 
the initial request


So, what is your use case precisely, and what are you trying to achieve ?

The cipher-mismatch was probably solved by something you changed in
your configuration. Re-generating the TLS certificate might have ended
some of the warnings about certs with a SHA-1 signature, but the
cipher-mismatch is a different beast and probably more important.

I just tested Firefox connecting to server that serves SHA-1 
certificates, and Firefox issues no warning (except in a web console), 
let alone to refuse the connection.
