In your servlet just look up the resource. should I initialise the connection in the Init method? how and when should I close the connection? You should close the connection immediately when you are done with it. Best not to pass references of them around. You would close them as a you would in a driver managed connection, that is Connection.close() ; and wat entries in the web.xml file will effect connection pooling?

Hi Patrick,
You use should use the servlet name you specified rather than the

Do you need the servlet-mapping as well ?

Re: How to release connections in connection pool during reload?
You need to release connections when you are done with them, con.close() ; This is similar to using a direct connection to the jdbc except this time the only difference is where you got the connection object from. Calling con.close() ; will release the driver back to the connection pool. Lucie Chan wrote: Hi, I'm using Tomcat's connection pooling feature which is implemented with Jakarta's DBCP to manage database access, and I just noticed that each time when I do a reload (either via Ant or Tomcat manager), a database connection is added to the database server. Though this isn't a big problem in the production environment, but it's a bit annoying during development when I'm interactively developing and reloading the application. Currently, I will run reload till all the database connections have been exhausted, and then restart Tomcat server. There must a better way to do this. How do I destroy or reuse the connections in the pool?

The second connection is painfully slow and task manager only reports a 50% CPU utilization. After doing some reading on SMP/native threads and windows, I wrote a test java application that spawns n infinite loop threads from a single JVM with a delay between each creation. Sure enough one cpu (task manager reporting 50%) and then the other cpu are consumed (task manager reporting 100%). This test tells me that Java is capable of using both CPU's via native threading and some black magic in the windows dll's but that this scenario isn't happening in tomcat. Is it possible for tomcat to use more than one CPU or is there a critical flaw in my logic? -Dan - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: trouble with servelts
You are missing the servlet.jar file, which contains the neccesary
classes for your servlet to compile.
Just make sure your compiler can find the jar file in your classpath. If
you have a IDE like netbeans
than you have it easy, just mount the jar file, and you will be able to
compile without problems.

Re: Servlets with JDBC connectivity
But this means I still have to get a connection, create a statement, and execute a query or update on the statement in every servlet where I want to use the connection. Yes, it locates the connection details (i.e., the JDBC connection method, the database name, user and password) somewhere centrally so that I don't have to keep coding it, but all of the connection overhead still has to be dealt with in every servlet in a webapp. The datasource solution that a few people in the list (including me :) ) have been asking you to look at provides a connection pool to your web application. In your code where you ask for a connection from JNDI, you are actually getting a connection from the pool, which is already setup. When you call the close() method of this connection, it is not actually destoryed but returned to the connection pool, ready to be used.

The first point is to use a singleton to set up the database connection - or more correctly the connection pool. This way you can request a connection and return it to the pool easily. Of course every time you use one you will have to use try-catch blocks. Sorry no way around that. Both Tomcat and J2EE specification support javax.sql.DataSource objects over JNDI. That is how we handle it elegantly. A DataSource object is specified by the administrator and created by the container. Container then deploys it under specified JNDI name. A servlet (or EJB) can then lookup this object and use it, something like this: import java.sql.*; import javax.sql.*; import javax.naming.*; InitialContext ic = new InitialContext(); DataSource ds = (DataSource)ic.lookup( java:comp/env/jdbc/MyDataSource ); Connection conn = ds.getConnection(); At least, I think that's what it's doing. Am I missing something? Here's what I want. In every servlet in my webapp, I'm only going to be using one of a very few database connections. I'd like to be able to do something like: Test.executeQuery(SQL) without doing any setup because the Test class handles all the setup, initializes the connection the first time it's called, etc. Basically, it's a singleton class that never gets an instance created because if I create an instance, I'd have to pass it around to all the servlets in the webapp, which would kill the convenience of having it be available with minimal overhead. Oo, oo, oo... As I've been sitting here writing this, I had a brainstorm. What if I create an abstract class that has all the database connectivity built into it as static methods, but is just waiting for a connection method, a username, and a password. Then creating a new JDBC connection which is visible to all my servlets is just a matter of making a concrete subclass that defines those three variables and inherits all the functionality from its abstract parent class. Any reason this is a horrible idea?

Re: Servlets with JDBC connectivity
I think this link over here, might give you a hand. http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html There are samples there for databases like mysql, but I think you should be ok. Todd O'Bryan wrote: This may not be the right place to ask this, but if you can direct me to the right place, I'd appreciate it. I'm looking for a design pattern that someone must have already thought through so that my head can stop hurting. Here's the problem: I'm designing a webapp that has several servlets that all access a database (or a couple of databases, actually) to either update or retrieve information. Rather than initializing these connections multiple times, dealing with SQLExceptions in every class that uses JDBC queries, and generally doing things multiple times, I thought I'd put all the database stuff into a single class. I created a setUp() method that initialized the database connection and then used static methods so I could do something like SQLUtils.executeQuery(a SQL statement); SQLUtils.executeUpdate(another one); anywhere in my webapp. If the database connection had not been created, it got created before executing the SQL statement. If it was already created, it just got done. I handled all the nastiest exceptions in the SQLUtils class, so I didn't have to deal with them elsewhere. You can probably guess the next part. I've discovered I need to connect to more than one database, and this design does not support that. Creating instances of a SQLUtil class would be a big pain, because then I have to pass those around between my servlets and I lose one of the huge advantages of this approach, namely a single, globally visible interface to the database. I thought about multiple classes, one for each database I'm connecting to, but I know that can't be right on so many levels. Meanwhile, I'm a little stumped. How do people handle this elegantly?

MySql times out idle connections. If your pool implementation doesn't
take care of weeding out dead connections you need to add

Re: Problem with ConnectionPool on Linux
Actually I took the nightly build of DBCP a week before it went into
release, built it on my own and replaced the one that shipped with
tomcat (since I couldn't find a pre-built binary). I think you do need
to change commons-pool as well. You also probably need testOnBorrow as
well for this to work.
With the dbcp that shipped with tomcat, if my db connections in the pool
timed out (being idle), dbcp wasn't able to handle it.

I have searched the email archives and I don't see anything that explains
this problem. Any help would be appreciated.

Billy, the second line implies that you did not include the classpath to

with javax.servlet.ServletException.

Re: innocuous Servlet kills Tomcat
The digester error actually provides you more info than you think : org.xml.sax.SAXParseException: The content of element type web-app must match (icon?,display-name?,description?,distributable?,context-param*,filter*, filter-mapping*,listener*,servlet*,servlet-mapping*,session-config?,mime-mapping*, welcome-file-list?,error-page*,taglib*,resource-env-ref*,resource-ref*, security-constraint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-local-ref*). See , servlet definitions come first. Define them first, then the associated mapping if needed. The order in which you define the servlets themselves do not matter, what matters is that servlet defiinitions come first before the mapping. You can have a look at the full dtd here : http://java.sun.com/dtd/web-app_2_3.dtd Paul Wallace wrote: Hi, I located the problem.

This would seem logical but for the fact that the mapped Servlet preceded the Servlet mapping?

Re: ClassPath with Tomcat 4.1

[OT]Re: Mobile phone on serial port - Howto send sms?
Another option is available to you John-Paul, specifically, http://www.kannel.org which is a wap and sms gateway. This gateway is based on linux although you can use cygwin to compile and run it, far from ideal but it does work and is usable enough for testing. The gateway does support most GSM modems and supports other major protocols like SMPP, CIMD... for connecting to telcos. Once you set it up you can send sms through it's http interface. So from your servlet or business logic class, just make a http call to the gateway with the correct parameters and your sms will be sent of. A library like commons http-client will be quite useful in this case. FYI : kannel is open source.

In the servlet or jsp you could do :
String text = request.getParameter(subject) ;
Then do whatever you want with it.

Subject: RE: How to cache the user's input in a jsp page?
Check out JSP's implicit object collection
For example, if you are using user sessions you can put any Object onto
the session, this will then be available whenever the user accesses the
page.
To use the session object simply use
session.setAttribute(identifier, Object);
So to save an Integer (Objects only, not primitives) for example
Integer foo = new integer(10);
session.setAttribute(fooint foo);
To retrieve it next request use
Integer foo2 = (Integer)session.getAttribute(fooint);
There are other implicit Objects including application (the jsp view of
the Servlet context) but this is globally visible so shouldn't be use to
store session type variables (IMHO)
Or you could write your own cache :)

Re: dbtags and tomcat 4.1
If you poke around in the mailling list for the taglib project you will find a mail or two about this, if I remember correctly had something to do with the tag not confrming to the taglib specification that tomcat provides. You could use jstl instead, but from my experience SQL in the jsp is more trouble then it is worth and causes imense headaches when you want to do something complicated. Just a suggestion but it could be a good time for you to have a look at migrating to Struts or some other framework which suits your needs :D Mickael Cappozzo wrote: Hello, We wanted to migrate from tomcat 4.0 to tomcat 4.1.24, but we encoutered the following problem: When a query return nothing, the query's body is displayed on the JSP page if the page contains another query returning something. example: In the table Users, we don't have user with username toto and with have a user with username test if we write the following in a jsp page: sql:statement id=getUserTest conn=myConn %-- THIS QUERY RETURNS THE UserID --% sql:query SELECT UserID FROM Users WHERE username = 'test' /sql:query sql:resultSet id=getUserIDTest sql:getNumber position=1 to=userIDTest/ /sql:resultSet /sql:statement sql:statement id=getUserToto conn=myConn %-- THIS QUERY IS EMPTY --% sql:query SELECT UserID FROM Users WHERE username = 'toto' /sql:query sql:resultSet id=getUserIDToto sql:getNumber position=1 to=userIDToto/ /sql:resultSet /sql:statement On the page we saw: SELECT UserID FROM Users WHERE username = 'toto' We noticed the following: if we add an attribute: loop, scope or another existing attribute in the resultSet tag in the empty query, the query is not displayed on the JSP page.

Re: Folder Permissions taken over by Tomcat 4
Is there a specific need to make that directory a smb share directory ? Hertenstein Alain wrote: Hello, We have a Red Hat Linux 7.2 Server with Tomcat v4.0.3 installed, and a web application configured, let's say myApps. In this webapps/myApps folder, there are folders which we have shared through SMB so that Windows users can access them, and we have also changed the folder's permissions, so that these users can modify their contents. Everything works fine. The problem here is when we have to restart Tomcat 4, all permissions under that webapps/myApps folder are restored this way - User : Tomcat 4, Group : Tomcat 4. So this means that all our permissions settings are cleared ! And we have to set them back again each time we restart Tomcat 4 (in case of a server reboot, or major application change, etc), which is quite annoying. Is there a way to avoid this ?

Re: Tomcat 4.1 DefaultContext Bug?
Specifically what problems do you have when running the app as a war file ? Peter Harrison wrote: I have spent the last three days trying everything to move from 4.0 to 4.1.

The problem however is that a Context that is specified will block unpacking of a war. There are some issues with using the war directly without unpacking - so I need to define the datasource in the DefaultContext. However this isn't working.

I'm trying to get Tomcat to handle a lot of traffic (4-5 million hits per day) and bumping up against a problem I for life of me can't figure out. So, I'm hoping someone else on this list has run into this problem and can help me out! Basically, I can't set maxProcessors higher than 384. If I do, Tomcat ends up choking (it doesn't crash, it just stops creating more request processors) and I get the following in catalina.out: Aug 18, 2003 5:05:02 AM org.apache.coyote.http11.Http11Protocol start INFO: Starting Coyote HTTP/1.1 on port 80 Aug 18, 2003 5:05:05 AM org.apache.tomcat.util.threads.ThreadPool$ControlRunnable run SEVERE: Caught exception executing [EMAIL PROTECTED], terminating thread java.lang.OutOfMemoryError: JVMCI015:OutOfMemoryError, cannot create anymore threads due to memory or resource constraints at java.lang.Thread.start(Native Method) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.init(Thread Pool . java:582) at org.apache.tomcat.util.threads.ThreadPool.openThreads(ThreadPool.java:4 60) at org.apache.tomcat.util.threads.ThreadPool.runIt(ThreadPool.java:293) at org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoint.java:5 36) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPoo l.ja v a:619) at java.lang.Thread.run(Thread.java:568) Now, I know that the JVM has plenty of memory left that it can be allocated and the system has plenty of free memory, so I'm not sure it's really a memory issue. As I said, Tomcat still runs and the memory allocated to the JVM increases, it just doesn't have nearly enough request processors created at the point this error happens to deal with all of the traffic. I've tried playing around with ulimit settings, but those didn't have any impact. I've also tried the Sun JVM and it did the same thing. Has anyone run into this problem or something like it before?

Re: Cannot Solve jdbc is not bound is this Context problem
If you copy the DB2 driver into $CATALINA_HOME/common/lib , then it
should be a jar rather than a zip or a tar file.
I think you should also change driverName to url.
Alan Nesbitt wrote:
We have been trying for over a week to solve this problem. It doesn't help
that we haven't used tomcat before, but our application works fine on
WebSphere. So I guess that it some configuration that we are missing.
We are trying to configure tomcat (4.1.24) to do a jndi lookup of a
DataSource which is a db2 jdbc app driver.
The Tomcat server.xml had a sample jdbc configuration which was modified to
the following...
Resource name=jdbc/SURESWIT auth=Container
type=javax.sql.DataSource/
ResourceParams name=jdbc/SURESWIT
parameternameuser/namevalue/value/parameter
parameternamepassword/namevalue/value/parameter
parameternamedriverClassName/name
valueCOM.ibm.db2.jdbc.app.DB2Driver/value/parameter
parameternamedriverName/name
valuejdbc:db2:SWPPDB2/value/parameter
/ResourceParams
The web.xml includes
resource-ref
res-ref-namejdbc/SURESWIT/res-ref-name
res-typejavax.sql.DataSource/res-type
res-authContainer/res-auth
/resource-ref
The Java code performs the following :-
if (ds == null)
{
try {
Context ctx = new InitialContext();
ds = (javax.sql.DataSource) ctx.lookup((jdbc/SURESWIT);
ctx.close();
}
catch (Exception e)
{
logger.text( IRecordType.TYPE_ERROR_EXC,
className,
init(ServletConfig),
Naming service exception: + e.toString());
}
}
When the above code runs it throws the following exception
init(ServletConfig) Naming service
exception:javax.naming.NameNotFoundException:

I have copied the DB2 jdbc driver file to $CATALINA_HOME/common/lib (I
copied it both as .zip and .tar as some web resources suggested tomcat would
only recognise it as .tar)
ANY and I mean ANY help would be greatly appreciated. Even if it's to say it
doesn't work with tomcat.

When you are guaranteed the thread will terminate either because of an error or because the assigned task has been completed.

Re: how to create servlet?
.java is the source file, the one you use to compose your program. It is like any other text file, you can use any text editor to create a .java source file. The .class file is a compiled version of the .java file, ready for execution by the servlet container. For your second question, you only need to define the servlet name, as you have already earlier declared the servlet name like this: servlet servlet-name SomeName/servlet-name servlet-classcom.company.name.Servlet/servlet-name /servlet So when you do the servlet mapping you use the servlet name instead. Your servlets should be located in $CATALINA_HOME/webapps/$WEBAPP/WEB-INF/lib/$JARFILE if you pack them up as a jar or in $CATALINA_HOME/webapps/$WEBAPP/WEB-INF/classes if you did not pack them up in a jar file. kitty winslet wrote: In WEB-INF\classes\ I always find 2 kind of file SendMailServlet.java and SendMailServlet.class, what is the difference btw *.java and *.class ?

Re: stalling servlets/jsps with wait/notify?
Why would the client stall in the first place ? If you can figure out that problem, the webapp could probably scale higher than 5 clients. Richard Heintze wrote: I had an interview with a prospective client today who has problems with a current web application (written in lotus notes?). He knows from his present implementation that he can have no more than 5 simultaneous web clients accessing a certain resource that resides on a machine different from his tomcat server. Any additional clients must stall until the others are done. Hmmm Well on page 40 of Jason Hunter's Servlet programming book it explains that static variables are shared among multiple servlet instances. Hmmm... well JSPs are servlets, I wonder if I could create a static variable in a scriptlet (just for testing, of course) and use wait and notify to stall web client #6 until one of the other finish.

Re: DataSource configuration in web.xml instead of server.xml
You can have a context for your application defined in a seperate xml file but not in the web.xml. If you read the dtd for the web.xml you'll see that this is not allowed. Simply copy your context that works and paste into a new xml file, which has the same name as your webapp. So if you had your app as test.war, then create test.xml. Put these two in the webapps directory, it should autodeploy properly without much hassle. It should work. If it doesn't then restart tomcat.

Re: IOException: failed to communicate with MySQL
Write a dbkeep-alive, schedule it to run say every 15 minutes. Works for me. I use jcrontab.sourceforge.net to schedule this.

Thanks for pointing this out. I've read the thread Tomcat problems every morning. However, no solution was suggested in that thread. One can assume the solution implicitly: increase default MySQL timeout from 8 hours to say 48 hours. However, if my application stays idle for 48 hours during holidays, it will disconnect after that. Does anyone else have a suggestion on how to improve on this? Hello, My JSP application very often after night, in the morning stops communicating with MySQL database. I get an exception each morning (the exception body goes below). The application starts to work again after I restart it from the Tomcat Manager. Maybe someone else also had this same problem? My server configuration: Linux Redhat, Tomcat 4.1.24, Java 1.4.1. My assumptions where the problem might be: the MySQL connections are eaten by another application or they are eaten by my application somewhere inside and never closed. Or maybe during the night when no one is working with my application it somehow frozes? Can anyone give me a clue how to start debugging these early morning crashes? Another clue: Connections to the database are made through an SQLManager which is a class written by another programmer. The class is a singleton.

The order of the elements in the web.xml file must be in a specific order.
As the error message states, they must appear in this order:
(icon?,display-name?,description?,distributable?,context-param*,filter*,fil
ter-mapping*,listener*,servlet*,servlet-mapping*,session-config?,mime-mappin
g*,welcome-file-list?,error-page*,taglib*,resource-env-ref*,resource-ref*,se
curity-constraint*,login-config?,security-role*,env-entry*,ejb-ref*,ejb-loca
l-ref
You probably just have your nested elements out of order. Perhaps you have
a servlet or servlet-mapping before your context-param which is
invalid.
If you want to know more about the format of the web.xml file, you can
download the servlet specification from Sun here:
http://java.sun.com/products/servlet/download.html
Here's a link to the 2.3 specification
http://www.jcp.org/aboutJava/communityprocess/final/jsr053/
and refer to chapter 13 - Deployment Descriptor
Once you have that sorted out you can see what next falls out.
I would also recommend that you learn on the latest version of Tomcat
available which is 4.1.24 right now.
http://jakarta.apache.org/tomcat/
http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.1.24/
FYI, If you happen to be using Windows I'd also like to offer this advice:
I used to download the .exe version and install it, but I would now
recommend the .ZIP version as it doesn't fiddle with your configuration.
Sure, getting it to run as a service is a bit trickier, but for development
the less fiddling the better.
As a zip file I start tomcat from the command line with
SET JAVA_HOME=(whichever jvm I want to use)
SET CATALINA_HOME=(Whever I unzipped tomcat to)
%CATALINA_HOME%\bin\startup.bat
Example:
SET JAVA_HOME=C:\j2sdk1.4.1_02
SET CATALINA_HOME=C:\jakarta-tomcat-4.1.24
%CATALINA_HOME%\bin\startup.bat
This way you can also try different JVM's and different tomcat installs
easily.
Good luck.

Actually setting the $CLASSPATH should work. I prefer the 'javac -classpath' method, as you can specify the jars that you want instead of a bunch of directories in the $CLASSPATH variable. Try combining that with a shell script, saves you from typing too many times. Better yet, use ant. Jonathan Michael Nowacki wrote: Holy cow!!! It worked.

Re: Session Replication/Clustering 4.1.x JDK NIO Bug fixes
Just curious Filip, but is any of this going to make it's way into a future version of Tomcat as a standard feature (the clustering and session replication, not the bugs.) ? Filip Hanik wrote: hey ya'all, Running today on Solaris I discovered a bug in the way java.nio is implemented on Solaris 8(Intel) JDK 1.4.1. This problem could exist in other JDK versions as well. The problem is that when a thread reading from a socket channel calls selector.wakeup(); the selector doesn't wakeup from its sleeping state. Hence the replication works exactly once only. I have added in a sleep timeout for the selector (in server.xml the property tcpSelectorTimeout has been added). Play around with this timeout, setting it to small means CPU times goes to waking up the thread. Setting it to high means you can get some delay in your replication. I have defaulted it to 100ms. The new version including updated documentation can be found at http://www.filip.net/tomcat-clustering.html. The same fix has been applied to the Tomcat 5 CVS branch Best regards.

To compile the servlet, get yourself a java jdk (1.2 or higher) and compile the source servlet with javac. I *think* there is a tutorial on Sun's website which tells you how to build your first servlet and how to install your jdk. Check it out.

Re: win 98 :displaying a simple servlet
servlet.jar comes with tomcat which contains the servlet api. You can use this if you wish to compile with your servlet. Jon Schachter wrote: thanks. i have jdk 1.4.but apparently since i downloaded J2SE, and not J2EE, i didn't get javax.servlet and javax.servlet.http. i see where you can just download those from sun. i think that will fix my problem.

Re: ?? Trying Again: Newbie Question about Root Context ??
Send a copy of your server.xml file, I don't see that commented out in mine. I'm pretty sure it isn't though. Tony LaPaso wrote: Hi all, I posted this question over the weekend but nobody really seemed to know the answer. Several people speculated but nobody knew. Altough I'm sincerely hoping for an answer, please, if you don't know for sure, don't guess. :) I just installed TC v4.1.24 on Win 2k. The installation worked right out of the box. I didn't have to make any changes to the server.xml. TC is up and running just fine but I'm seeing something strange I was hoping someone could explain: Here's a quote from the TC documentation: ...you MUST define a Context with a context path equal to a zero-length string. This Context becomes the default web application for this virtual host, and is used to process all requests that do not match any other Context's context path. Okay, that's fine, but when I look at conf/server.xml I see this: !-- Tomcat Root Context -- !-- Context path= docBase=ROOT debug=0/ -- Why is this commented out? According to the documentation cited above there must be a context path equal to a zero-length string. The quote I cited seems to contradict what I'm seeing in server.xml. As I said, even though this is commented out everything seems to work fine. In other words, if I browse to localhost:8080 TC does indeed serve up webapps/ROOT/index.jsp. Is the docBase named ROOT the default? If so, then the documentation seems out of date. I believe in past versions of TC it was definitely necessary to have a context path equal to a zero-length string. If anybody knows (for sure), I would really appreciate an explanation.

Re: status 404 when migrating from 4.0.4 to 4.1.24
If you put this : servlet-mapping servlet-nameinvoker/servlet-name url-pattern/servlet/*/url-pattern /servlet-mapping in your web.xml then you can use this to load your own servlets without defining them. If remember correctly ; then the class that would be loaded in this example : http://localhost/myapp/servlet/stuff would be stuff.class. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: status 404 when migrating from 4.0.4 to 4.1.24
The servlet invoker lets you call your servlet in the webapp without actually mapping one in the web.xml So you can do this in the browser: http://localhost/myapp/servlet/stuff You're not really missing much. Don't know if the other containers do that. Sven Köhler wrote: servlet-mapping servlet-nameinvoker/servlet-name url-pattern/servlet/*/url-pattern /servlet-mapping one stupid question, what does the invoker-servlet do? i always write my own servlets without using it, and my mapping them directly using web.xml. i wonder, if i'm missing a great feature. is the invoker servlet supported by all servlet containers? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: MYSQL and TOMCAT
java.sql.SQLException: Update failed, possible duplicate entry Let's see you have a table info with one field and that field is a primary key right? If I remember correctly, primary keys in a table have to be unique, so maybe you are calling your method with the same data again and again ? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
