OK. I used a fresh set of the Tomcat demo files and rebooted the server and now it works. I'd still be interested if anyone's got an idea about what was up though. I don't mind when the code is complicated and things don't work due to my lack of understanding - I can usually figure things out in the end - but it gets frustrating when things are simple and don't work due to something mysterious. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Java EE (J2EE) Programming with Passion!" group.

[java ee programming] Lab 4008 - Tag Files Problem
I'm having a problem with Excercise2.3 when I try to add an fourth

--- begin panel.tag--
<%@ attribute name="color" %>
<%@ attribute name="bgcolor" %>
<%@ attribute name="title" %>
<%@ attribute name="subtitle" %>
${title}: ${subtitle}
--end panel.tag--
The apposite parts of panel.jsp are
%@ taglib prefix="tags" tagdir="/WEB-INF/tags" %>
[code omitted]
First panel.
[code omitted]
When I try to run the page I get this error

[java ee programming] Re: Servlet long processing cancelation when browser closes.
I used threads only to simulate delay in servlet preocessing. Other
than that it all happens in one thread inside the request.How do I
specify the timeout server close on disconnected requests, can I get
some notification in the code to break the loop in request? Would the
timeout affect connections while browser still waiting fro response
but no data is being sent?
Thanks,
Mike

[java ee programming] Re: Servlet long processing cancelation when browser closes.
For timeout configuring, in case of Tomcat, you should look for Connector
configuration. There are connectionTimeout and keepAliveTimeout attributes.
In regards to notifications... I'm not sure there is a straightforward
solution. Maybe it worth lookinag at event listeners?

[java ee programming] Re: Servlet long processing cancelation when browser closes.
If client terminates the connection the server will close it after the
timeout (should be specified in server configuration). Another thing is that
IMHO it is not a good idea to manage threads manually inside of any
component - you should leave it for container, it is container's job to
control threading for you.

[java ee programming] Servlet long processing cancelation when browser closes.
Hi,
I have a servlet which processes a request for a long time. It suppose
to keep doing stuff in the loop inside doPost and send data through
response's out writer. Effectively that continuously appends data in
the clients browser .
But the problems accures when client just closes the browser. Inspite
of the broken connection the response's writer stream in the servlet
never gets closed, thus servlet is unaware of the brocen connection,
and keep dumping data into the writer without any errors. How is that
posssible? And how do I detect and cancel long request processing in
case of browser disconnect?
This is the servlet code which never stops:
protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
HttpSession session = request.getSession();
System.out.println("Session " + session.getId() + " started");
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try
{
while (!out.checkError())
{
try
{
Thread.sleep(1000);
} catch (InterruptedException ex)
{
ex.printStackTrace();
}
Date date = new Date();
// TODO append output to the client browser here
out.println(".");
System.out.println("Session " + session.getId() + "
data sent at: " + date);
out.flush();
//break; // _TEST
}
} finally
{
System.out.println("Session " + session.getId() + " finished");
out.close();
}
}
Thanks,
Mike

Subject: Re: [java ee programming] Clear Console Screen
Hi,
find the os name (with SystemProperties)
if is windows you can use
Runtime.getRuntime().exec("cls");
on linux you can use
Runtime.getRuntime().exec("clear");
But I think if you want to clear the console maybe is the case you need a
desktop application (can be very simple, one JDialog and one JPanel with
JTextArea inside).

[java ee programming] Re: Clear Console Screen
The clue to the problem is in the error message - try putting your code inside
a try/catch clause.
e.g
try {
Runtime.getRuntime().exec("cls");
...
} catch (IOException e) {
e.printStackTrace();
}

[java ee programming] Re: Clear Console Screen
Hi,
you shouldn't do that as you would brake the platform independency of
java. Better try to run a System.out.println(""); for like 30 times in a
loop.
If you really want to execute a operating system command (syscall) do this:
Runtime.getRuntime().exec("cls");
This is just a hint! Look up Runtime class in the Java Docs.

[java ee programming] Re: Question about LAB-4002
Hi Mark, Normally the user is the one who enters the address in his browser (either by keying in or by clicking some link). When working with NetBeans, one can define as one of the project properties, which URL do load for the Run action. For the hello2 project, this has already been defined for you. In the projects that you'll create in the future you'll probably have to define it by yourself. Access this definition from within NetBeans by right clicking the project name (from the Projects view) and selection of Properties. Wait a while (NetBeans is very slow at the beginning) and then select the Run category.

Hi Harmeet ,
Use 'action' in your form tag .
Also you need to define servlets mappings in web.xml if you are submitting to

The first homework instructions say to use Netbeans 6.1. Can I use NetBeans 6.5? Also, if I use Tomcat instead of Glassfish?
