You can still do this (by using 4.1.7 at least) by declaring all the resources under global resources with different names and then providing a ResourceLink in each context with the generic name you are using to each the appropriate resource.

Why does doSomething() need to be called? For a servlet there are three methods that you can use to perform processing service(), doPost() and doGet. Normally, you would not deal with service() but simply define an appropriate doPost or doGet method to do your processing. Both of these take as parameters the request and response objects. You should be aware of this as you have a working app. How does your webapp work? Do the users access a JSP and then that JSP performs all processing and displayes the results or is a servlet called when a user accesses a url and that servlet performs all the processing and forwards to a JSP to display the results? These are the two most common models. If you can let us know how your app works then we can help you. I can assure you that what you are trying to do is not outrageous.

Re: Big problem 2, the Mission!
Hi,
Let me see if I understand your problem. You have a JSP that creates
business objects, the business object internally used some DAO objects,
each DAO object when it performs it's processing calls DAO.getConnection
(this happens to take some parameters which I assume are hardwired into
DAOMain).
Because you have a lot of JSP's your easiest (but not the simplest!)
solution is to use JNDI. You could use parameters but then you would have to
modify every single JSP.
To each context add an environment entry of the following type:
Context ...
..
Environment name=db.url type=java.lang.String
value=jdbc:postgres://localhost/mydb /
/Context
To read this value you need code of the following form (courtesy Will
Hartung), you can add it anywhere, in your DAOMain, business object, etc.
You probably want to add it to the function that initialises your database
parameters.
import javax.naming.*;
InitialContext ctx = new InitialContext();
String dbUrl= (String)ctx.lookup(java:comp/env/db.url);
I have tested this Tomcat 4.1.7.
Regards.

Subject: Big problem 2, the Mission!
First I would like to thank all of you for ur patience with me...
my problem is I HATE reading documentation and references. I'm a
trial-and-error developer... sometimes that's good, and sometimes (like
today) it is not.
I will now try to explain my problem with some code to be sure I won't get
missunderstood.
But before anything... I don't have ANY Servlets here... I was totally
tripping... I tought a Servlet was the solution, but it is not.
I only have JSPs (which I know are Servlets) and Beans.
let's go:
I have a webapp with lots of JSPs and classes... in my JSPs I have something
like this:
%@page import=SomeBusinessObject%
%
SomeBusinessObject sbo = new SomeBusinessObject();
sbo.setParameters( request.getParameter(id1),
request.getParameter(id2) );
sbo.getSomeAttribute();
sbo.setSomeAttribute();
sbo.update(); sbo.delete()... etc.. etc...
... lots of other code...
%
this SomeBusinessObject will have a reference to a DAOSomeBusinessObject
where all the queries (insert, delete, update, select) resides... and that
setParameters() method is only for it to know which row of the database
we're handling with, the parameters match with the table keys of course. But
that is irrelevant here.
I have also a class called DAO which provides all of the other DAO*s with a
Connection... this is done internally within each DAO*.
the method bellow is in DAO, which all the other DAO*s call to get the
Connection.
public static synchronized Connection getConnection(String usr, String pwd,
String url, String driver) {
Connection con = null;
// some code here to make some checks... irrelevant
try {
Class.forName( driver );
con = DriverManager.getConnection(url, usr, pwd);
} catch(ClassNotFoundException cnf) {
System.out.println (*** Erro: driver nao encontrado!
+cnf.getMessage());
} catch(SQLException sql) {
String detalhes = URL = +url+\nUSER = +usr+\nPWD = +pwd;
System.out.println(*** Erro ao obter conexão!
+sql.getMessage()+\n+detalhes );
}
// a little bit more code
return con;
}
now the problem - I'll try to be very clear (my english SUX, please be
patient with me).
the webapp points to a specific db URL... this URL is in the DAOMain... if I
want to change the db, I'll have to change DAOMain, recompile it, and
overwrite it... nothing weird so far. Right?
The big thing is: this webapp gets replicated... so I copy the ENTIRE dir...
classes, JSPs, jars... everything... and I know how stupid this is... and
that's the problem...
- in each of these webapps, the only thing that changes is the JSPs, and
maybe the DB url...
WHAT I WANT IS: I want to put our classes, jars and the oracle driver in the
$TOMCAT_HOME\common dir, because they don't change from one webapp to
another BUT since DAOMain holds the URL this is not possible (each
webapp must have its own DAOMain)... I wanna create a CLASS that will
receive a request from DAO or DAOMain (residing in \common) and provide a
Connection based on the Context of the JSP that used SomeBusinessObject -
DAOSomeBusinessObject - DAO.
or maybe DAO could do that... let's say I would write some code in
getConnection() to find out where (Context) it is (well... actually DAO is
always in the same place.. but the JSP that uses it, and calls it, is not)
to provide the right Connection... BUT without ANY change of parameters to
getConnection(), since that would snowball into a mega change of method's
signatures that would end in the JSPs...
(I'm tired...)
well... that's it... I don't think I can be clearer than that... my english
stops here... :)

The compiler is correct, what happens if an exception is raised. It goes to
your catch block and writes the debug but then there is no return after
that. Maybe you should be re-raising the exception again.

Re: Need Ideas... big problem! (long)
Or even simpler why not store it as a parameter in the server.xml. You will need to add the parameter to each of your contexts in the server.xml as follows:- Context path=/examples docBase=examples .. Parameter name=db.url value=jdbc:postgres://localhost/mydb override=false/ /Context And then in your servlet code you use the following to retrieve it (from your servlet):- getServletContext().getInitParameter(db.url) Regards. - Original Message - From: Christian J.

(long) I have a huge problem here... and I can't think of a simple solution for it, I'm hoping u guys can give some light. :) Let me first describe the environment here, then the problem. We have here a webapp called FAP (c:\tomcat\fap). It is composed of: /fap/*.jsp (like a hundred of them) /fap/WEB-INF/classes/finep (this package finep has a lot of subpackages) /fap/WEB-INF/classes/finep/DAO.class -- here the problem resides... /fab/lib/OracleDrivers.jar the class DAO provides the Connection to an Oracle database... so far, everything is fine... but here's the thing... this webapp gets replicated... the whole dir, because there are other instances of this system with small changes, and we didn't have the time to create a self-configuring app to allow that... so we copy the whole dir and make the necessary changes... BUT... the classes never change... only the JSPs... AND another thing that may change is the database (and of course DAO)... so how it is done? we have /fap with DAO.class pointing to a specific db URL and; we have (for example) /fap2 with a few JSPs changes and DAO.class pointing to another URL. this of course sux! If we wanna change the database of a specific webapp we have to re-compile DAO and place it there... and if we change a class (any class) we have to update it in ALL the contexts... What I want: I would like to place the package finep and the OracleDrivers in the global context (c:\tomcat\common\classes, \lib), so all would be pretty and centralized; and create something like a Connection Dispatcher (also in the global context) that would receive requests from the JSPs and provide a Connection to the specific URL based in which context that JSP was when the request was made. I don't know if that's possible... I'm just guessing... of course I want do this as painless as possible... cuz we have like 80 classes and more than 150 JSPs... to confuse???

Consider the following simple fill-in form: fif.jsp This doesn't work because c:out will call PageContext.findAttribute() which looks for attributes and not parameters. Section 3.2 of the JSTL spec says of identifiers: searches for the named attribute in page, request, session (if valid), and application scope(s) in order and returns the value associated or null I don't think I should set the attribute at the application or the session levels as they don't seem to belong there. I dont' know how to set attributes in the page context so I had a look at the request level. I need to add attributes to the request before I forward it but the setAttribute() method isn't defined for HttpServletRequest. These methods are inherited from ServletRequest, they're not HttpServletRequest specific. So you can use request.setAttribute and then use pageContext.findAttribute as you intended. Struts would provide much of this and more. But that depends on how you want to structure your application.

Re: Tomcat 4.0.4, jndi, jdbc and postgresql [long]
Hi,
I notice that you are doing the JDBC lookup in the init function. This
doesn't appear to work properly (at least on 4.1.6), move the initialisation
code to the doGet/doPost and see if that helps. This cured my JNDI/JDBC

I've just started to write servlets. Servlets that only do processing,

Context envCtx =
(Context)initCtx.lookup(java:comp/env);
DataSource ds = (DataSource)
envCtx.lookup(jdbc/BookDB);
Connection con = ds.getConnection();
} catch (Exception ex) {
throw new ServletException(Couldn't open
connection
to database: + ex.getMessage());
}
}
public void destroy() {
try {
con.close();
} catch (SQLException ex) {
System.out.println(ex.getMessage());
}
}
public void doGet (HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
HttpSession session = request.getSession();
// set content-type header before accessing the Writer
response.setContentType(text/html);
response.setBufferSize(8192);
PrintWriter out = response.getWriter();
// then write the data of the response
out.println(html +
headtitleDuke's Bookstore/title/head);
}
}

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.

I know this isn't a technical problem, but I was hoping for responses from real developers. I thought it was a simple question, and have always received excellent and quick responses from the tomcat mail list in the past, so the problem must be with me or the way I am asking. Can someone please help me improve myself? Is this a stupid question? Have I perhaps asked it incorrectly? I am open and receptive to any constructive criticism available (I can take it, but maybe you could send a direct response if you want to be extremely brutal?!) All I really want to know is how many applications real developers are putting on one machine in the real world. I am just looking for an abstract number, and I am not worried about system configurations at this time. The problem is that there is no generally useful answer to your question as stated. It depends even more on the nature of the applications you are talking about (when the answer might even be zero for a particular server configuration) as the size of the server (an answer based on a 64-CPU mega-server with 4 gigabytes of main memory isn't going to help you on a small single-CPU Linux box with 64 megs). There are no architectural limits on the number of webapps a single Tomcat instance can support, or the number of Tomcat instances on a single server. It all comes down to what resource bottlenecks you run into first in your application environment. In many webapp environments, the first bottleneck encountered is often database access, followed by the number of simultenaous requests being processed. Neither of those bottlenecks has much directly to do with how many different webapps you are talking about. Thanks! Craig ORIGINAL QUESTION: I am doing some Tomcat cost/benefit projections for my company. I need to determine the maximum number of applications that will run on Tomcat and still provide stable performance. I am not interested in a theoretical number at this time, just seeking information about what real developers are actually doing with real applications. At this time, I am not interested in what machine types, OSs, configurations, versions, are being used. I understand the answer to my questions will depend heavily on these issues as well as on the applications themselves. I just need to come up with a realistic number of instances/apps which are being run on a single machine by real users. I am seeking an answer to the following two questions: Number of Tomcat instances I am running on one machine: Number of individual applications I am running in all instances of Tomcat on one machine: Please feel free to respond to the mail list, or to me directly at [EMAIL PROTECTED] (if we don't want to clog the list with answers to this question). I will post a final resolution message to the mail list when I have come to some sort of conclusion.

Help with JNDI Catalina 4 (May 30 build)
Hi, I am trying to use JNDI to access some resources.I wonder if someone knows how to use the GlobalNamingResources. Here is a snippet from my server.xml GlobalNamingResources !-- the file based cache for all web applications -- Resource name=rohas/filecache auth=Container type=com.rohas.cache.FileCache / ResourceParams name=rohas/filecache parameter namefactory/name valuecom.rohas.cache.FileCacheFactory/value /parameter parameter namecacheDir/name value/tmp/cache/value /parameter /ResourceParams . I have then defined a link to this in my context as follows :- Context path= docBase=www.compuvision.co.uk debug=0 reloadable=true crossContext=false cookies=true ResourceLink name=rohas/filecache global=rohas/filecache type=com.rohas.cache.FileCache / The code to load the resource is defined as follows ::- /* Get the file cache from the context via JNDI */ initCtx = new InitialContext(); envCtx = (Context)initCtx.lookup(java:comp/env); /* retrieve the file cache */ fileCache = (FileCache)envCtx.lookup(rohas/filecache); The resource is loaded as part of the startup for my servlet. When I start catalina I get the following error:- javax.naming.NameNotFoundException: Name rohas is not bound in this Context at org.apache.naming.NamingContext.lookup(Unknown Source) at org.apache.naming.NamingContext.lookup(Unknown Source) at com.rohas.util.MasterServlet.init(MasterServlet.java:76) at javax.servlet.GenericServlet.init(GenericServlet.java:258) at org.apache.catalina.core.StandardWrapper.loadServlet(Unknown Source) at org.apache.catalina.core.StandardWrapper.load(Unknown Source) at org.apache.catalina.core.StandardContext.loadOnStartup(Unknown Source) at org.apache.catalina.core.StandardContext.start(Unknown Source) One answer could be to define the resources in each context, but this is a pain as I am probably going to have about 6/7 contexts each of which use this shared resource. Can anybody help ? Am I using the global resources in completely the wrong way ??? Regards, Arshad
Re: problem..plz help me out
Hi, What is in your server.xml. Have you defined a virtual host for puneet, and how have you defined the Context. Send yout server.xml as an attachment and we should be able to see what the problem is. Do you get a response by trying http://localhost:8080/yourcontext/servlet/abc (replace yourcontext with the name of your context).

Re: How can I redirect only JSP pages to Tomcat?
Ooops, should have read more carefully. The Tomcat-IIS howto contains the appropriate instructions on how to setup IIS to redirect a url to Tomcat. You need to look for this document under Tomcat 3.2.4 (should still be applicable to Tomcat 4 as you are using ajp12)..
