Re: Please help me
I'm guessing the snippet below is from your struts-config.xml file. I tried to make that work and couldn't even on a straight forward textbook example. It was much easier to define the datasource in the [context].xml file in conf/Catalina/localhost, use the DBCP db pool, and then write my own db access code. Besides, I think I saw something to the effect that the feature you're using below might be removed from future Struts releases. I'm sure there are people on the list who can confirm or deny that suspicion. --David Rajesh wrote: This is Rajesh. I am working on webApplication project.The project Environment is in Struts1.1 Framework with jdk1.4.2_01,WebServer as Tomcat5 on O.S Linux connecting back-end Mysql. I am trouble shooting a problem. I have properly closed each and every connection whenever I open a connection.So the db connection is properly maintained.And the Session too is properly maintained.In struts1.1 struts-config.xml just for connection pooling I've coded data-source tag like data-sources data-source type=org.apache.commons.dbcp.BasicDataSource set-property property=driverClassName value=com.mysql.jdbc.Driver/ set-property property=url value=jdbc:mysql://ip address/contextname/ set-property property=username value=/ set-property property=password value=/ set-property property=removeAbandoned value=true/ set-property property=removeAbandonedTimeout value=60/ /data-source /data-sources So for every 60 seconds the connection pool is checked to freeze-out the unwanted Connection. Every thing works fine on first day but on the consecutive day it troubles. MAIN PROBLEM STATEMENT IS On the next day when I try to login to my site it is not letting me login. I am sure there is no problem in my coding, because the whole day the site is working perfectly well. Only for a period of time the db access is not working.

To use servlets you will need a servlet container/webserver like Tomcat. To compile servlets some .jar files from Tomcat are necessary.

Hi all,
I can't find an answer to this question. Plese help me.
I have an apache-tomcat(4.0.3) system installed. I use a connection
DataSource with a Oracle database (I have a resource in server.xml with
type=javax.sql.DataSource). --- Instruction in the JNDI Resources
HOW-TO section of Tomcat 4.0.x.
My question is this. If Oracle DB crashes and it has to been restarted,
does my web application,that uses DataSource, have to be restarted?
I have a class with this static block:
static {
try {
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup(java:comp/env);
DataSource ds = (DataSource) envCtx.lookup(dbName);
con = ds.getConnection();
if (con == null)
System.out.println([ERROR] Connection null);
} catch (Exception ex) {
System.out.println([ERROR] Errore = + ex.toString() + \n
+ ex.getMessage());
con = null;
}
}
and I have a method:
protected synchronized Connection getConnection() {
while (conFree == false) {
try {
wait();
} catch (InterruptedException e) {
System.out.println([ERROR] Exception getConnection() =
+ e.toString());
}
}
conFree = false;
notify();
return con;
}
In the servlets of my web application I call getConnection() to take
the connection: if db is restarted what happen?
Thanks for your help

Re: Please help me!!
Well I use the default pool DataSource of tomcat 4.0.3.
I get a initial connection (--- static block) and then I return that
with getConnection() method.
I suppose that when the db is restarted my connection becomes null, but
I'm not sure.
I'm planning to use DBCP: is it possible using it with Tomcat 4.0.3?
How can I install it?
Does DBCP resolve the problem of the DB restart?
Thanks

RE: Please help me!!
You may want to look into these two classes from oracle.
oracle.jdbc.oci.OracleOCIConnection
oracle.jdbc.pool.OracleOCIConnectionPool
They should be in the classes12.jar.
This will preclude you from using the thin driver, but probably provide more
stability in connection pooling.
Read Oracle documentation here.

Re: Please help me... URGENT
Hi, If you need to get it up and running fast, just use Tomcat with SSL. You can always add Apache later if you think it will boost performance. Setting up an Apache+SSL+Tomcat server can be tricky if you are a newbie (and even if you aren't). A lot of this depends on what you are running and how heavy the demands on the server will be. If you have a lot of static pages (and maybe even if you don't) Apache with SSL and Tomcat may be faster. In that setup you use Apache to do the SSL, which is theoretically faster because it is a binary on the server. In reality the extra overhead of the transfer from Apache to Tomcat of dynamic pages may nullify any speed advantages. - Original Message - Please help me .

I would assume that the use of SSL implies sensitive data being handled by the Win 2k server. Why risk compromising that data by using IIS?

My question is being analyzed far too deeply by the diligent developers on this mail list. snip Well, although I agree with other posters that answering your question will not provide you with any useful information, here goes... I am developing a REAL application using Tomcat. Development is on a G3 PowerBook running Mac OS X 10.1.5, Tomcat 4.0.3 standalone, and MySQL something or other (recent, anyway!) with mm.MySQL JDBC driver. Performance is very good. Production will be on some kind of Sun box which also runs Samba (masquerades as an NT server) for local workgroup. Production DB will be Oracle 8i, which will probably slow down the app somewhat, but still confident the car will go fast enough! Now, apart from the information that the Mac is an excellent platform for Java apps, I don't know how this helps you, but hey... :-) Martin -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

YES! You've hit it! I AM asking the question about how fast the car will go. At this time, I DON'T care about the type of car or engine! My question is being analyzed far too deeply by the diligent developers on this mail list. The type of responses I was hoping for would have had developers proudly boasting something like: At my company we are successfully running 17 applications in two TC instances or We are running one TC instance with four apps or We have one app. I am not interested in app type or size or anything like that. Based on the information I have seen, I should be forced to conclude that TC is not being used for any real applications, but I KNOW this can not be true - there are far too many intelligent and competent people monitoring the mail list. Unfortunately (for me), no one has yet proclaimed success. I understand that when it comes time to actually implement TC, the questions regarding OS, JVM, type of apps, etc will become VERY important.

RE: Please help me improve my question skills (number of tomcat a pps)
Jeff - We are using Tomcat to provide a Web front end for a mainframe application -- so at most two or three clients at once hitting the server. The box is Win2K or WinNT 4. The application is a bunch of JSPs and a couple of Java Beans which use TCP/IP to talk to the MF. We are not quite released but the Beta code has been running very nicely in Tomcat 3.3.x and 4.0.x for 3 or 4 months now. Everyone that has seen it has been impressed. Does that help?

Re: Please help me improve my question skills (number of tomcat a pps)
Hi, So the question reduces to:- 1. What are the extra memory requirements for a virtual host/context? 2. How much longer does it take to decide on a servlet/jsp to invoke for an extra virtual host/context? From my (limited) understanding of Tomcat, I would say the answer to both of these questions is negligible compared to the memory/overhead of processing a typical request. So your question reduces to how many requests can be processed by your instance, and that depends very much on your application. The distribution of the requests amongst the applications shouldm't matter. Can somebody more knowledgeable confirm the extra resource requirements for virtual hosts/contexts.

RE: please help me
First thing to do is look at the log. tomcat 4 is much better at logging than version 3. If you did not chnge the logging entry in the server.xml the examples log file will show details about what is happening when your webapp (context as Tomcat4 calls it) is loaded. If you simply see an entry about what is expected in a web.xml the most likely thing is that you have servlet-mapping entries mixed in among your servlet entries. Now all the servlet mapping must appear after all the servlet entries. The parameter icon has changed to become small or large - again look at the log for details. Another thing we noticed in Windows (if that is your platform) was that in Tomcat 3 the WEB-INF directory name could be lower case, Tomcat 4 insists that it must be upper case. hope this helps, Jon G-S -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Janarthanan, Prasanna Sent: 14 April 2002 14:04 To: '[EMAIL PROTECTED]' Subject: please help me we have our web application running with tomcat 3.2.3.

RE: please help me
thanks for the clarifications, i have worked with this tomcat for the past week. it is now giving a strange error for my context added in server.xml file. just i did it like explained in the documentation. But soon after i start the tomcat and see the log files, it is giving error : -- marking context as unavailable due to previous errors. error entering the context /(my context name). i searched the cause of this problem . but u know there are no relevant answers for this in any of the tomcat mailing list. I wonder how come it is so.. All what i think is, the web.xml file of my web application is not able to act for tomcat 4 which was working fine for tomcat 3.2.3. If i see the web.xml file of examples web application in tomcat 4, it has some extra elemts like filters which are not available in my web application. Also there are no proper documentation for configuiring the web.xml file of the web application to work with tomcat 4. Please dicuss about this as i wonder this could be important for tomcat 4.

Put a break point in between and examine Context and its contents. Also
check the spelling/case of datasource lookup name. If you are creating the
Datasource yourself, check for any exceptions during its registration. If
the DS is on an application server, talk to your Server admin.

Re: PLEASE HELP ME: JNDI ERROR 1
I think that the context is ok bacause the log file (catalina.out) tells me:
[DEBUG] InitialContext = javax.naming.InitialContext@46110f9b
[DEBUG] lookup java:comp/env = org.apache.naming.NamingContext@3700f9b
[DEBUG] Datasource = Resource reference to a factory for java.sql.Connection
instances that may be used for talking to a particular
database that is configured in the server.xml file.
So ds isn't empty: the exception is thrown when I call:
Connection con = ds.getConnection();
The Datasource is Tomcat's Datasource ( I have followed jndi tutorial)

Re: Please help me on a question about TOMCAT OR APACHE + TOMCAT
Tomcat Standalone is not an enterprise webserver, and will not stand up to the pounding that Apache can take. I think you would find that your response time drops off rather quickly if you are hosting 200 active virtual domains. If you don't serve many concurrent requests, and don't need the power and flexibility of apache, tomcat standalone is fine.

Howdy. I found a very useful document that describes in simple terms how to set up Apache + (n * Tomcat) in load-balancing fashion. That may be something to consider just for flexibility. I currently have mine configured with only one Tomcat, so the load balancer isn't doing much for me, but it's trivial for me to add another internal machine with Tomcat and share the load. http://www.ubeans.com/tomcat/index.html Good luck.

RE: Please help me on NT Authentication
Well, if you create a custom realm you can specify anything your 'lil heart desires in the config.xml file. You have all the right you need to access your NT domain controller if you can log onto the network with your domain username and password. Are you using a 2K domain or an NT domain. Ask your admin if you're not sure. -Original Message- From: Bruno VERNAY [mailto:[EMAIL PROTECTED]] Sent: Thursday, December 20, 2001 9:23 AM To: Tomcat Users List Subject: Re: Please help me on NT Authentication Can't you change the IP adresses and other passwords ?

RE: Please help me on NT Authentication
Well, for Bruno and Group, here is what we did. I don't know if it is going to work
out for you.
And Yes, this is a TC solution not weblogic. Don't be miserable!
We had two implementations since we were in the middle of an exchange upgrade and just
rolled out
a 2K domain. We use exchange and are setup for NT authentication on exchange. Given
this information
Implementation
1) My first realm pop-ed off the exchange server with domain username and pass.
Since the exchange server uses NT authentication that worked. It is/was kinda hackey,
but it did for a few weeks until we rolled out exchange 2K.
to get the roles, the realm then went and looked into a company wide addressbook (an
LDAP server) for a particular attribute
that had been reserved for just such purposes. In there we added roles with ';'
semi-colons as delimiters.
so
if(popOffExchange(username,pass) == GOOD)
{
roles = checkLDAPforRoles(attribute,ssearchbase);
}
We couldn't use the JNDI realm with TC because our LDAP at the time required no
authentication.
2) Win2k domain with Active Directory (AD) and exchange 2k. Similar to above, but with
everything
being one-stop login. Because AD is an LDAP server, and requires domain logon to get
into it,
authenticating against it using the credentials supplied and then going straight to
the user branch
of the LDAp tree was great. Exchange 2K was essential because it adds a field in AD
for customAttributes
which we use for roles. We couldn't use JNDI realm here as we don't have a single user
account to lookup info
and neither our admin nor I knew were (or if) the passwds for NT were in AD.
if you are short on time you can probably buy the bins from my company, but they only
work with exch 2k, and win2k domain
with AD. If you are in that situation then this will just plug in.
Chris

Subject: Please help me on NT Authentication
Hi,
I am building a system for the Intranet. We have a NT network. I wanted to know if
by any means I can use the username and password that is registered in the NT Server,
so that when a user logs in to NT system, he should be automatically logged in to my
application built on Tomcat?
Can anybody guide me on how to go abt it?
Thanks in anticipation

Re: please, help me!
I have a web aplication and this aplication read some system properties and this is funcion corret in tomcat, but now I want to put a copy of this application and I want to read same system properties but with other values that I will define. My question is: Can I define two different shells (enviroment) in tomcat (two context with a shell each one) in ordet to manage two copys of that system properties? I tried with two JVM's differents but I didn't get. Thanks Monica What kind of system properties? The name of apps. is strongly the same? I think you can do this if the apps. names are different.

RE: *** Please help me
It would appear that your Tomcat is not working correctly (looking at the isapi log it determines it should redirect, however the the service() method indicates that its failing. Does Tomcat work on port 8080? I would guess that the Microsoft JVM is causing your problems. Try installing either Sun's JVM or IBM's.
