JSVC ignores hosts in my server.xml...
Hi! I have the following configuration: Fedora Core 1 JDK 1.5.0 beta 2 Tomcat 5.0.27 I installed jsvc according to tomcats instructions. Heres relevant part of my server.xml: Engine name=Catalina defaultHost=localhost Logger className=org.apache.catalina.logger.FileLogger / Realm className=org.apache.catalina.realm.UserDatabaseRealm resourceName=UserDatabase / Host name=shop.ablogic.org appBase=webapps2 / Host name=localhost appBase=webapps Aliasablogic.net/Alias Aliaswww.ablogic.net/Alias Aliasablogic.org/Alias Aliaswww.ablogic.org/Alias /Host !-- XXX -- Host name=siblumber.com appBase=/home/sibl/web/ deployXML=true Aliaswww.siblumber.com/Alias Aliasshop.siblumber.com/Alias /Host And inside my $CATALINA_HOME/conf/Catalina/siblumber.com/ROOT.xml I have the following: ?xml version=1.0 encoding=UTF-8 ?

If I try to run Tomcat5.sh start as root, however, only my localhost element is parsed. There are no errors inside the log whatsoever, and I have no idea what the hell is wrong. My Tomcat5.sh jsvc configuration is set to switch me to tomcat5 user. On both of my folders (and all their sub-files) /usr/tomcat5 and /home/sibl/web the owner is tomcat5:tomcat5 and privileges are set to ugo=rwx, meaning everybody has unlimited access to all folders, therefore eliminating it as a possible issue. Does anybody know what the hell is the problem with jsvc? Any help is greatly appreciated. Best Regards, Ivan V. Jouikov (206) 228-6670 --- Outgoing mail is certified Virus Free.

Using SSL with different domains on one server
Hi! I have 1 server with multiple IPs. As far as I know, Digital sertificates work per IP per domain. So, how can I configure to make it so that Whenever user requests www.dom1.com, it forwards him to a certain IP (that can be done through my DNS ), and then a specific certificate is used?

YAY YAY YAY! REJOICE! Thanks man! You saved the day! Looks like I was on the right track when thinking that I should save file differently, I just didn't follow my intuition :( And sorry about blaming tomcat - I can't blame myself, now can I? BTW, do you happen to know how to make it so that ALL my files are saved as Unicode? -Original Message- From: Mark Thomas [mailto:[EMAIL PROTECTED] Sent: Monday, July 19, 2004 11:43 AM To: 'Tomcat Users List' Subject: RE: [URGENT] When I type Russian in my .jsps, it displays it as a bunch of squares! Ivan, This isn't a tomcat problem and I would appreciate it if you would refrain from blaming tomcat without foundation. The problem is that your JSP is not saved in UTF-8. Try the following in Eclipse: - Right-click on the .jsp file in the package explorer - Select properties - In the 'text file encoding' section select 'Other' rather than 'Default' - Select 'UTF-8' in the now enabled drop down list - Click 'Apply' - Click 'OK' - Save the file - Redeploy your webapp On XP you can also save JSPs in UTF-8 using Notepad. Select 'Save As...' and select the encoding you require from the drop down list at the bottom of the save file dialog. I have just cut and pasted the example Russian text from your original e- mail into a JSP. Before changing the encoding I saw a series of ?s in the browser. After correcting the JSP file encoding I saw the expected Russian text in IE.

Retrieveing Unicode stuff from MySQL 4.1.x ?
Hey!
Im trying to make it so that
my clients could use different languages when entering stuff into my froms. What I am doing right now is:
All my pages have %@ page language=java contentType=text/html; charset=UTF-8 at the top
When I retrieve parameters I use the
following procedure:
String text = request.getParameter(text);
text = new String(text.getBytes(8859_1),UTF8);
This seems to work perfectly for throwing
parameters from page to page. Also, it
seems to work fine to ENTER stuff into MySQL (I look at mysql through GUI
client, and I can see all my Unicode stuff correctly).
However, what is troubling me, is that when I retrieve that Unicode stuff from DB and
try to display it, I get a whole bunch of junk on my page. Heres how I retrieve it:
/**
* Returns a list
containing GuestBookEntry's ordered by date.
* @param page from
which page (page 1: entries 1 thru 5)
* @return a list
containing GuestBookEntry's ordered by date, empty list if none.
*/
public static List getEntries(
int page ) throws SQLException
{
Connection con = null;
PreparedStatement st = null;
ResultSet rs = null;
List entries = new LinkedList();
if ( page 1 )
throw new IllegalArgumentException(Page must be 1 or above!);
int startIndex =
(page-1)*offset;
try
{
con =
Manager.getInstance().getConnection();
st =
con.prepareStatement(SELECT name,email,date,IP,message FROM GuestBook
ORDER BY date DESC LIMIT ?,?);
st.setInt(1,startIndex);
st.setInt(2,offset);
rs =
st.executeQuery();
while ( rs.next() )
{
String name = rs.getString(1);
String email = rs.getString(2);
String IP = rs.getString(4);
String message = rs.getString(5);
Timestamp date = rs.getTimestamp(3);
GuestBookEntry
e = new GuestBookEntry(name,email,IP,message,date);
entries.add(e);
}
}
finally
{
try{ if ( con != null ) con.close(); } catch(SQLException e){ Logger.getLogger(problem).error(Can't
close Connection!,e); }
}
return entries;
}
And in my JSP page I simply display name and message
from the list returned by this function
Does anyone know how to make my JSP page display my
stuff correctly? I also tried doing:
%= new String(message.getBytes(8859_1),UTF8) %
But that
just gives me a whole bunch of boxes instead of text.
Any help is
greatly appreciated.
Best Regards,
Ivan V. Jouikov

When they compiled the latest stable Tomcat, did they bother to test it before
putting it out?
I looke through the entire google, and through this entire list, and I found lots of
people having this problem. Yet, I didnt find any solutions (that worked for me
that is).
Basically, heres what I have:

will ROOT (/) context, folder hello interfere with context (hello) ?
Something just popped in my mind. If you have a ROOT context which has a folder named hello, And you have a context named hello When you request localhost:8080/hello/ Which one are you gonna get? The ROOT context or the hello context? I will try this out tomorrow, but I wonder how tomcat handles this? Best Regards, Ivan V. Jouikov (206) 228-6670 --- Outgoing mail is certified Virus Free.

RE: I've officially decided that JSTL is one of the worstthingsto ever happen
What the hell are you talking about? I am all for java. Java is my #1 language.
Oh for crying out loud Ivan! You challanged my assertion that Java is the
number one language asking for the source of the stats and I give them
to you but you just go on whining. Please take your trolling somewhere
else. Get A LIFE. and as to C++?
My trolling? I don't even know what that means. And I do have a life.
Huge file sizes
I wonder what compiler, and linking options are you using? I do not have
a problem with my executables being huge at all. Then again, I don't
use frameworks that are inefficeint hogs. Sounds like the programmer.
Huge file sizes was said about C++ COMPARATIVELY to C. Any program in C++
will be much bigger than exactly same program in C.
100% guaranteed memory leaks
Sounds like the programmer. My code doesn't have memory leaks! Then
again, I know how to write disciplined code, something that quick and
dirty programmers can't understand. I also know how to use tools that
track memory leaks.
Looks like you've never written a 600MB program.
And lo The Heavenly Father doth rest. And whilst He rest, His hand
accidentally brushed the keyboard and somehow keyed in the following code.
Troller ivan = new Troller();
ivan.setIrrational(true);
ivan.setOverEmotional(true);
ivan.setLife(null);
ivan.setClue(null);
ivan.setThinkingStyle(Psychosis.THINKING_STYLE_BLACK_AND_WHITE);

Source of this statistic?
I assumed that this was fairly common knowledge. I remember when it
surpassed C++ in Febuary of 2000 (I thought at the time in development
hours). Having been a Java programmer since 1997, this was a pretty big
deal for me. I even remembered the month/year it happened (which made
it
easire for me to find this report). So here is the original report, a
Bloor Research study from Febuary of 2000. It even has a cute little
graph that plots the various languages-- http://www.bloor-
research.com/research_library.php?pid=282
Now that I look back at it I see that this is when the *demand* for java
skills surpassed that of C++ skills. It looks like it was just March of
last year
(http://www.sun.com/aboutsun/media/presskits/edge2003/factsheet.pdf)
that
that Java actually surpassed C++ in development hours. This was of
course
the eventual outcome of it's demand surpassing all other skills. The
data

RE: Tomcat 5 Context problem
When you simply copy WAR file into $CATALINA_HOME/webapps directory like Lomboz does, you don't need to configure a context to describe a path, Tomcat will automatically make it available as localhost:8080/FolderName Where FolderName is the name of the folder inside /webapps/ where you application is. IF you do want to configure a separate context, you would want to do it inside server.xml. It's described very well at Jakarta.apache.org documentation. You can also toy around with /META-INF/context.xml (located similar to /WEB-INF/web.xml), and there specify the context like you would in server.xml. But I'd be very careful, because Tomcat seems to be very buggy when it comes to the second approach. -Original Message- From: Koon Yue Lam [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 07, 2004 8:12 PM To: [EMAIL PROTECTED] Subject: Tomcat 5 Context problem Hi, it really not a problem because I got everything work.

Java is King, there are really no ifs, ands or butts about it.
As to your performance issues, I don't have them so I can only sugest that
you can examine your environement, your compiler options (are you using
hotspot?) and your getters. All of my bottlenecks are in my DB calls. I
have done performance analysis and never came up in my EL. As I sugested
earlier, maybe you can run hprof and see where the bottleneck really is?
Also, I considered myself a fairly hardcode C++ developer (having done it
from '95 to 2002). If I am ever in a situation where my memory usage is
critical, I'm almost certainly in C or C++. If performance is important,
I consider C or C++. But IPC, threading, and networking is so
phenominally better on Java not to mention the benefits of garbage
collection and all of it's other features that I am hard pressed to leave
it or go JNI. I did need JNI recently for some file system stuff that I
wanted tweaked (traversing file systems with 100s of thousands of files).

RE: I've officially decided that JSTL is one of the worst things to ever happen
See below for my replies
What should we use instead? Welcome to the front page of JSP
manual:
% if( yourmoma ) { %
Do some things
% } %
To me, it seems EASIER than this:
c:set var=yourmoma value=%=yourMomaFromCode%/
c:if test=${yourmoma}
Do some things
/c:if
What happened to the good old idea of using JAVA, with all its
beautiful
features, in the JSPs themselves?
Understandable output? Do you really think you can find one
designer who
would understand a simple calendar written in tags? Hell no. And for
me,
as a programmer, understanding good old java code inside % % is MUCH
MUCH
easier than understanding all the tag BS. Besides, old java tags % % do
very good job of presenting understandable layout. %=% and ${} are
both equally to understand to me.
A key phrases in that example is To me, it seems EASIER... And for me, as
a
programmer... both equally to understand to me
But that is you, a programmer with experience using various programming
languages.
Why not use scriplets? Because of the development worlds experiences with
ASP and CF where pages were riddled with code and vew developers (not
designers) hard a hard time maitaining these view components.
View developers in large teams have their respective discipline and it
becomes more difficult for them to maintain thier tier. JSTL allows them
to
use familar syntax and structures from SGML/HTML and all those other
markup
languages, hence making it easier for them to display data, not
processing
it. Or would a company rather employ a perfectly good server side
developer
writing view code? If they have no usability skills it will be a waist of
the company resources.
The key phrase is display data, not processing it, which is what I agree
with. However, that's not what JSTL agrees with. Tags like c:if and c:foreach shift
XML from data to logic, which is NOT what XML is for. Didn't I say that before?
But you're missing the point, again: the (major) reason JavaScript is
NOT
server-side, is because of its sloppy syntax which is like a warm oven
for
bacteria - bugs just GROW in it. EL is making the same mistake over
again.
Valid point for JavaScript, but again treat JSTL-EL as a view helper
component not as a pure processing solution. Also did not mean to mention
EJB it had no place in this arguement.
That's one of the things that EL might be actually useful for:
printing
stuff out and escaping XML.
Exactly...
But again, you're forgetting that taglibs actually FORCES you not to use % %
code inside tags (when you make tag files). And tags like c:if and c:foreach have no
place in this world, I think we have a consensus on this.
But still, what if TModel might return a null value? Then you're in for
a
nice 2 hour debugging ride with your EL syntax, or a 5 second adding if
statement ride, if you used Java.
The null values should be handled in the Model or in a heavy Controller...
if those values are missing or a failure occurs send them to the
appropriate
view.
There are a lot of java classes that return nulls as part of normal operation.
For instance - sets. Set.get(someobj) returns null if object is not there. And when
you do ${my.set.blah.wee} and blah wasn't found, and you get some crazy EL error,
you'll remember my words.

Lets leave yourmoma out of this... lol

RE: I've officially decided that JSTL is one of the worst things to ever happen to mankind
1) Yes %=% was 10 times as fast. But Anything of simple complexity like
using a model object request %=% to get ugly real fast with many getters
and explict casts. There is a massive tradeoff in simplicity when you have
the following:
${myObect.myGetter.aValue}
Ahh must I repeat this again? First of all, it's not all that easy. You're
gonna have to do
c:set var=myObject value=%=myObjectFromCode%/ prior to using that.
Now, what if myObject.myGetter returns null? You're in for some fun hour-long
debugging session. I'd rather stick with
%
Set set = my.set();
Object value = set.get(weee);
If ( value == null || !(object instanceof MySuperClass) )
Return;
MySuperClass msc = (MySuperClass)object;
String myString = msc.aValue();
%
%=myString%
I'd trade these 10 lines of code for that 1 line of code IN A FLASH, because I
know, in the future, when there's a bug that's crashing my server, and my manager is
yelling at me cuz the clients r calling bank and telling them to refund their
accounts, because some variable was null and it says Thank you for your purchase.
Null has been shipped. I KNOW I will spend at most an hour locating the bug in my
Java code, whereas I'd spend days, if not weeks, if not re-write the entire
application, just to fix bug dug inside the EL code.
2) I get massive headaches reading all the extra %% in code. Add any
type
of loops of block and it gets even worse. JSTL is simpler to read if you
have good people writing consitent styles.
Yes I agree, JSTL is simpler to read. How about this, your write a calendar
using JSTL, considering all the loops and triggers you'd have to use. And then you
tell me how much easier JSTL is to read, ok?
3) XML is for what you want it to be. But as for using xml as the syntax
for
JSTL, it does make things simpler for other tool sets to integrate. It
also
is an easier trasitition from things like cold fusion and such.
True that XML is what you want it to be. Why don't we start programming in
Microsoft word? I mean, it is a text editor isn't it?
4) This arguement is the blanket arguement against any loose typed
languages.
I shall ignore it.
5) This sounds like people having configuration and training issue.
6) All my developers have switched to JSTL. They love it and the code is
much
easier to write and *more important* review.
Good luck with your developers. Can I have the name of your company plz?
I'll make sure never to buy anything from it.
7) This is just plain old trolling.

Hello, it seems I have missed a good conversation! Now for my two
pence/cents:
4. EL encourages sloppy syntax. It doesnt even have data types
(well it has on the bottom level, but not on the surface).
Remember JavaScript? Did you know that at first, it was
supposed
to be server-side scripting language? You know the reason it
didnt make it (one of the major ones)? Because of its sloppy
syntax and the amount of errors it caused. Why bring it back?
I agree that % code % is clearer, especially for debugging but I think
that using % % excessively leads to poor page design.
This is the most ridiculous thing I've ever heard. I think HAVING poor
designs leads to poor design. Using % % might make it look ugly, but it won't
affect the design itself (I am not speaking of graphical design here, I am speaking of
program design)
Embedding Java
code directly into a presentation page leans towards placing business
logic in the presentation tier, which is BAD design.
Isn't that EXACTLY what c:foreach and c:if tags encourage? Having logic
inside presentation? Embedding java code doesn't necessarily mean logic. % for (
Iterator I = collection.iterator(); i.hasNext(); ) { %
Do stuff
% } %
Seems much better than:
c:set var=myCollection value=%=collectionFromCode%/
c:for item=${myCollection} test=%=somecmplicated test here%
Do stuff
c:for
Again, it's not what u use (JSTL or java) that makes a bad design, its a bad
designer that makes a bad design.
If you have to
process your data objects on the presentation page you have a problem.
It is better to construct a bean that contains all the information
required for the page, embed it in the session when you serve the JSP
and just pull data out of the bean. Need to loop? Use iterators in the
bean. Need to construct a new object in the page? Why? This is
presentation!
Customer isn't worth the trouble? Maybe that theory of thought is the
reason why you're using Japanese mail server?
Good luck with your developers. Can I have the name of your
company
plz? I'll make sure never to buy anything from it

A tool is a tool. Rather than declare that a tool is worse than useless, it probably would be more effective to explain why you couldn't use it this time. It's a little easier that way to talk about what can be done, what tools could be used instead, where you might still profitably use the recalcitrant tool. Ok, so you're saying that if my task is to dig a hole, and there's a tool whose documentation says used for digging holes efficiently and easy, it automatically means that it's good for that task? You ever thought that good ideas don't necessarily mean good results? What if that tool is a vacuum cleaner? How would you dig a hole with a vacuum cleaner? I mean that's what its documentation says... The point is, some tools are just no good. If the customer or boss is willing to negotiate, positive information will be more useful.

I am not talking about presentation of code, (hell assembler can be presented well!) what I mean is that using JSTL and EL forces you to abstract yourself from the business tier as you have restricted ability to handle the data. WRONG. It forces you to do the OPPOSITE. Logical flow statements like c:if and c:for FORCE you to have business logic embedded in the pages. You ever read JSTL manual? I recal it says something about no need for java at all... By using embedded Java you do not have this restriction (which may be a good thing for performance or clarity) which can lead you to perform operations you shouldn't in a presentation processing. I agree that having a bad designer leads to bad design, but a good design can be poorly implemented. I propose that the use of embedded java can be poor implementation as it is all to easy to perform operations that you shouldn't in a presentation tier. Hmm.

Which means that when your java app is in competition with a native app, youve lost the market. In some very rare situations, maybe. Most software nowadays is waiting for the user 99% of the time. And even, when speed is important, reliability is always more important. In general, Java programs turn out to be much more stable. Furthermore, they are plattform independent.

I am new to this mailing list but I figured I would throw in my two cents:
(Please excuse my e-mail provider it interpreted the characters from
Ivan's
original message in some strange way
Needless to say I was a bit concerned about a few comments...
After getting convinced to try JSTL, I learned the following things:
1. JSTL and EL are inefficient. Tests on similar pages clearly showed
that. (compare - ${name} with %=name%, run in a loop 1 times,
you-?ll see the difference)
Sure it will be slower, it is really java classes under the hood trying to
hide complexity of scriptlet code. Is that a bad thing? Not really, helper
classes a great, we create them to handle business logic, why not more for
view components. The latest hardware is getting less expensive so I do not
feel this argument holds (especially with the new 64 bit processers and
DDR
memory).
You don't feel this argument holds? When you have a poor little tomcat
running 100 different web applications with 10,000 clicks/day on each, it DOES become
an issue. Your choice: get a new server, OR replace all the ${} with %=%. I've
been faced with similar situation many times, and trust me, it drives you nuts.
2. JSTL is cumbersome -? someone told me once that the reason they use
JSTL is because their designers are scared of %=% code, but they have
no
problem throwing around XML statements. Well, what-?s my advice to him:
hire new designers, and fire your high school students.
That is not nice to say about your fellow UI developers. Their specialty
is
usability and content development and if you ask my opinion most server
side
developers do not dedicate time to this discipliine. It is too much to ask
a
designer to learn a server side language when they are busy trying to keep
up with their specialty. The job positing to replace the high schoolers
will
be like all of those other rediculous ones you see on Dice these days
where
companies are looking for a laundry list instead of a solid developer.
I see your point, but you got me wrong. I am not suggesting that designers
should have to learn a whole new language, but I am saying that if a designer is OK
with this: ${name}, but NOT ok with this: %=name%, then it's a retarded designer.
EL syntax sort of encourages designers to be free to throw expressions and tags
around, which could result in SERIOUS logical errors when you pull some important ${}
out of the loop, and as a result, the dev will have to spend two day figuring out why
his code isnt working (this is where CVS is a charm). Bottom line is: designers
are for designing, not for throwing important stuff around.
3. XML is for data flow, not for logic. Whoever the hell thought of
tags
like c:if and c:choose should be murdered in the worst way possible.
With JSTL-?s exporting and importing variables, and all the logical
statements and loops, the whole idea of XML gets destroyed.
What should we use then for content development? HTML is done... no more
updates... It's replacement is an XML application known as XHTML. Looks
like
XML has more uses that just data... Oh did someone mention XSL? XSLT?
XSLT syntax xsl:If ... xsl:choose I wonder where Jakarta developers
got the idea
http://www.w3.org/MarkUp/Activity
What should we use instead? Welcome to the front page of JSP manual:
% if( yourmoma ) { %
Do some things
% } %
To me, it seems EASIER than this:
c:set var=yourmoma value=%=yourMomaFromCode%/
c:if test=${yourmoma}
Do some things
/c:if
What happened to the good old idea of using JAVA, with all its beautiful
features, in the JSPs themselves? IMHO, Java beats tag syntax in all aspects - easier
to write and understand, strict syntax, and more efficient. I don't know WHY would
you want to use XML for logic flow in the first place.
4. EL encourages sloppy syntax. It doesn-?t even have data types
(well it
has on the bottom level, but not on the surface). Remember JavaScript?
Did you know that at first, it was supposed to be server-side scripting
language? You know the reason it didn-?t make it (one of the major
ones)?
Because of its sloppy syntax and the amount of errors it caused. Why
bring it back?
Apples and oranges... Javascript indeed has it's problems, (heck I am
forced
to work with VBScript so I empathize here), but someone was smart enough
to
recognize Javascript's limitation and that is why it is a client side
technology. I believe JSTL uses reflection and if you don't like that you
sure as heck will never like EJB Container

RE: Tomcat and hot code deployment

As far as I understand, hot code deployment, is when you modify .class inside /WEB-INF/classes, and tomcat reloads it, correct? If so, is it true, that whenever it reloads it, the OLD instance of static objects, threads, and properties stay alive, that is, tomcat doesnt destroy them? Is that why many developers dont use hot code deployment on production servers? Because Ive been trying to debug my app, and I realized this pattern, and if I am correct, then my application is bug-free. I haven't attempted to verify what you are saying, but it seems to me that if the classes containing static variables exist inside WEB-INF/lib or WEB-INF/classes, they should reflect any changes made to code as the WebappClassLoader is dumped and recreated upon reload. Are you sure you aren't referencing static variables from classes existing in common/lib, common/classes, shared/lib, or shared/classes? Those wouldn't be reloaded.

See, one of my classes has its own static daemon running, and when I update that class's code, a new one gets loaded in, but the old one keeps running. Are you able to shut down the daemon thread at application shutdown? If you can get a handle to the thread, use a servlet context listener contextDestroyed() method to do the shutdown. The classloader can't be destroyed properly when a daemon thread is still running within it. I don't pretend to know the details of the destruction of the WebappClassLoader, so I'll leave the specifics to someone who knows better.

Are you sure you aren't referencing static variables from classes existing in common/lib, common/classes, shared/lib, or shared/classes? Those wouldn't be reloaded.

The context is your application so (context)/META-INF is right beside
your (context)/WEB-INF.
Tomcat will know whch host to use because that's where you deploy it (if
you use the deployer) or you can stick the app in the host's appbase
folder, and it'll work it out. It did with me anyway. Once it's
deployed, have a look in conf\Catalina and you find equivalent
context.xml files in there too.
As Apache acknowledge, they just write software that they give away for
free, and documentation and support are just extras when they get time.
There are a couple of books on Tomcat that go into more detail and
explain how things work. (Again, my experience).

Correct.

To answer your other question: this file is associated with the webapp
because of its location in the context dir or WAR file. That's how the
manager app/Tomcat/etc know what to do with it.
I don't know what's up there now, but this was described on the Tomcat
site when I made the switch to using context.xml many moons ago. ;)
In fact, for Tomcat5 use of context.xml is encouraged.

Can server.xml be reloaded without restart?
If I am hosting a large number of applications on my server, and I add a new application every couple of hours and every application requires having its own DB pool (aka Resource entry in server.xml), how can I make it so that my server.xml gets reloaded automatically? Because if I restart it, I'll loose all the current sessions and have downtime for a few seconds, and that's no good... Any advice? --- Outgoing mail is certified Virus Free.

You can keep the Resource tags with the webapp. See the Tomcat docs for context.xml. The short version is, everything you put under a Context tag, you can put in a separate, per-webapp file. When that webapp is updated, the rest of the container is undisturbed. Icing on the cake: app-specific settings stay with the app, making it more portable within your infrastructure. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --- Incoming mail is certified Virus Free.
