RE: Documentation ... : Your Advices please

[Sue Roe]

I think most people would probably use later versions of both Java and
Tomcat if they were going to set an environment up from scratch now. So I
would suggest it better for you to upgrade now and document for later
releases.

Hello All,
I am thinking of writing a document of how to set up. Apache +
tomcat + mod_jk with Apache using SSL. for free.
I am using Apache 1.3.* and Tomcat 4.1 and this works very nicely
 I have this running on my linux box for 2 years + now. 

I need your advice if I create a document of how to setup this will
it be use full. I am thinking that tomcat now being 5.5.* and 
apache 2.0.* will it be worth my time for the peoplpe or do you
think I should upgrade as well 

Regards
Guru

Merlia driver error

[Sue Roe]

Hello

We have a system set up with Tomcat 4.1 and SQL Server 7. We use a Merlia
jdbc driver to communicate with SQL Server via a connection pool.

Occasionally users get the following error when they first access a servlet
that needs to call a stored procedure...

***
EmployeeDAO_Pool: com.inet.tds.SQLException: java.net.SocketException:
Connection reset
***

.. and they are thrown out.

I am trying to find out exactly why this error is thrown, then I can find a
way to sort the access failures out.

Has anyone experienced the same thing?

Thanks

I am running Tomcat 5.5 with SQL Server on a separate machine.

I am getting the following error at random times:

Java.lang.Exception: java.sql.SQLException: [Microsoft][SQLServer 2000

I have been unable to determine a trigger for this error - it just seems
to happen randomly.  When it occurs, no user can then log in to the

to be made for subsequent logins.

Has anyone seen this and can point me to a solution?

RE: Tomcat 5.5 and SQL Server

[Sue Roe]

Ok. I haven't any experience with that, but I can say we were having similar
sporadic errors here with a Driver from Inet software (Merlia.jar),and
having upgraded it recently, the issue seems to have been resolved. I was
told that it was something to do with SQL Server throwing the connections
out, occasionally. 

So possibly it's a driver bug, not maintaining your connections. That's as
much as I know!

Good luck...

IIS, Tomcat and NTLM Authentication

[Sue Roe]

Hi

 

We have just upgraded our server software, running a Java application, as
follows:

 

From:

IIS 4, Tomcat 4.1 - both running on same server - NT4

To:

IIS 5, Tomcat 4.1 - both running on same server - Windows 2000

 

 The application is to be available to all staff, either over the Intranet
or the Internet.

 

An issue has arisen with NTLM authentication. We extract a users
domain\username details using NTLM Authentication, the code is listed at the
bottom of this e-mail. This mechanism worked 100% on the old configuration.
Unfortunately with the IIS server upgrade and change in OS the
authentication details do not seem to be being picked up in two scenarios. 

 

1.  IE 6, unless Enable Integrated Windows Authentication is disabled.
We don't really want Browser settings to affect access.
2.  IE 5! (We are trying to force client sites to upgrade to IE6, but
still why does the NTLM Authentication break down here?)

 

The IIS settings are as follow:

Default Web Site: 

Anonymous Access - OFF

Basic Authentication - ON

Integrated Windows Authentication - ON

Jakarta Virtual Directory:

Anonymous Access - ON

Basic Authentication - ON

Integrated Windows Authentication - ON

 

If anyone has had any similar experiences or knows of any other mechanism to
retrieve domain/username, it would be great to hear.

 

Thanks

Sue

 

 

Code to Extract domain/user Details


***

String auth = request.getHeader("Authorization");

if (auth == null) {

response.setStatus(response.SC_UNAUTHORIZED);

response.setHeader("WWW-Authenticate", "NTLM");

return;

}

String domain = "";

String username = "";

if (auth.startsWith("NTLM ")) {

byte[] msg = new
sun.misc.BASE64Decoder().decodeBuffer(auth.substring(5));

int off = 0, length, offset;

if (msg[8] == 1){

byte z = 0;

byte[] msg1 = {(byte)'N', (byte)'T', (byte)'L',
(byte)'M', (byte)'S', (byte)'S', (byte)'P',

z,(byte)2, z, z, z, z, z, z, z,(byte)40, z, z, z,

(byte)1, (byte)130, z, z,z, (byte)2, (byte)2,

(byte)2, z, z, z, z, z, z, z, z, z, z, z, z};

response.setHeader("WWW-Authenticate", "NTLM " +

new sun.misc.BASE64Encoder().encodeBuffer(msg1));

response.sendError(response.SC_UNAUTHORIZED);

return;

} else if (msg[8] == 3) {

off = 30;

length = msg[off+17]*256 + msg[off+16];

offset = msg[off+19]*256 + msg[off+18];

String remoteHost = new String(msg, offset, length);

length = msg[off+1]*256 + msg[off];

offset = msg[off+3]*256 + msg[off+2];

domain = new String(msg, offset, length);

length = msg[off+9]*256 + msg[off+8];

offset = msg[off+11]*256 + msg[off+10];

username = new String(msg, offset, length);

String employeeNTLogin = domain + "\\" + username;

context.log("User NT Login: "+ employeeNTLogin + ":: " +
new Date(System.currentTimeMillis()));

session.setAttribute (Constants.DATABASE,
context.getAttribute(Constants.DATABASE));

Employee userEmployee=null;

// 1. Get Employee Object for NT Login of User & Roles

try {

userEmployee =
myEmployeeDAO_Pool.getDetailsByNTLogin(employeeNTLogin);

} catch (DAOException daoex){

}

session.setAttribute(Constants.USER_EMPLOYEE,
userEmployee);

etc etc

RE: IIS, Tomcat and NTLM Authentication

[Sue Roe]

Thanks Allistair. 

Your blog was very interesting I had in fact already found it. I think we
should probably upgrade here so I will be sure to read it when we do.

Since posting this query I have in fact found a fix, typical! I explored the
contents of the Authorisation header and noted that rather than the auth
String starting with 'NTLM' it starts with 'Negotiate' in the scenarios that
didn't work! The encoded Domain and Username where still there, so I just
retrieved them as well.

Thanks for your reply

Regards
Sue

ISAPI redirector HELP ME!

[Sue Roe]

Hi

 

I am having a bit of a nightmare and hoping someone may be able to help. I
have Tomcat 4.1 / IIS 5 on Windows 2000 Server.

 

Basically all was working swimmingly until someone deleted the 'conf'
directory under Tomcat 4.1 installation, then re-started our server...
Tomcat obviously wouldn't start. I have restored the 'conf' directory that
we found on a backup. Tomcat starts fine again, but the redirection is now
not working...

 

Any ideas gratefully received!!! I have reinstalled Tomcat, and set the
filter up again in IIS but its now redirecting. This is a live system and I
will kill the person who deleted the conf file if I can find them ;-)

 

Many thanks
