How to run servlet without using Web.xml?But Tomcat now uses a web.xml for its global server-wide configuration.
If you'd like to invoke a servlet with:
http://host/servlet/ServletName
you have to enable the invoker servlet.

How to run exception using JSP?

How to run exception using JSP?

Why would you need the <%%> between the if else blocks? Even if you attempt to write some data within the blocks in java, you will still get an error. For example, this is illegal:
if(done)
System.out.println(true);
System.out.println("Hello World");
else
System.out.println(false);
}The compiler is expecting the 'else' to be directly after the body of the if. If it encounters anything else, it will complain. So you cannot do this in jsp either, regardless if it's a different technology, it's the same compiler.

How to run java program from website?

Hello
I'd like to know how to run java program from my web page.
I'd like to push some button in this web page so java program that would be on my server
would pop-up. Can it be done automaticaly upon running this web site? (without any buttons - I just enter website and program pops up).
Cheers

I rather thought about RMI. But I could try servlets. So how it would look like?.
I would make http request in browser (enter address) and program would show up in its window?. And I would not have to change anything in my program?. This program would run then on both boxes?. One remotely and one not?.
But I would have to learn some basics, I've never worked with servlets. Could you suggest some good sites about it?. With ready examples so I could tweak them to my purpose.

How to run VI using bolean control?

How to run VI using bolean control? Do I need to use invoke node or something else?
Thank you in advance.

You cannot start running a vi using a boolean on the front panel of that same VI. Detecting the state of the control requires the VI to be running.
Maybe you can clarify WHY you need to do this. The run button is for VI development. Once you have a final application, it should be set to "run when opened". The actual code could start out in a wait loop (or wait event) such that pressing a certain button will trigger execution of the main code as needed.

How to run java program created in Sun Java Studio

Hi All,
sorry for easy question. I'm new in java.
I have created Swing/AWT application with Sun Java Studio. I can run it using Sun Java Studio and it works properly. How to run this application in DOS-promt using "java ....."? I think, I shall define all classpathes but I dont know exactly.
Enviroment:
WinXP
Sun Java Studio (C:\Sun\studio5u1_se)
SDK (C:\Sun\j2sdk1.4.2_04)
Application files (C:\Sun\My)
Thanks.

change this to yours
set path=c:\j2sdk1.4.1_01\bin;c:\j2sdk1.4.1_01\jre\bin;%path%
set classpath=c:\j2sdk1.4.1_01\lib;c:\jdk1.4.1_01\jre\lib;%classpath%
go to directory where code is
javac CLASSNAME.java
then to run it
java CLASSNAME
note also look at executable jar files

Has anybody noticed how much RAM Java uses?

Hi Everyone,
I have been playing around a little with Java programs, and far out the RAM in my computer gets strained!!! I don't know how many times a Java application has completely locked down my 667MHz, 320Mb computer. My brothers 1.2GHz, 256Mb runs Java a little better, but really to play "hard ball" Java style you would need a 2.4GHz Pentium 4 with between 512 and 1024MB of RAM.
Obviously Sun Microsystems have looked to the future with Java. They have played their cards very well by creating a programming language that is a little hard for current computer hardware to run.
In ten years time when we are talking about computer hardware, we will have hard drives with terabytes of space sitting on our home PC, don't worry about clock speeds, there won't be any, the Quantum computer has already taken care of that (for all those novice Quantum Guru's out there - information exchange takes place in no time, that is not faster than the speed of light... the messages simply takes place in no Time.). Technology moves so fast that it is hard to keep pace, unless of course you are addicted to Reading!!
At the moment we obviously do not have the hardware to run massive Java applications. So instead we have garbage collection. How effective is garbage collection, and what can be done to improve it?
I have read a little about garbage collection, but it sounds quite haphazard, possibly unreliable. Obviously object orientated code takes up a lot of memory, by learning garbage collection techniques I hope to improve my coding. If anybody who reads this thread can contribute anything of personal experience related to garbage collection, it will be greatly appreciated. Code is always good, but I am also looking for peoples ideas about improving garbage collection, even if those ideas are not viable in the current version of the JDK.
Thanks for your comments and I hope that you enjoyed reading this thread.
David

Hi,
if it was meant as a joke, I enjoyed it - but if your opinion is really that of java, you have posted, I would suggest to read some of the documentations provided by Sun and you will find out, how java uses memory and you will also find out, that garbage collection is not the point, you have to worry about, because it is automatically done by the JVM. Also javac has parameters, where you can manipulate the memory usage of the JVM. So, please start reading in the case this was not just a joke :)
greetings Marsian

This is confused and confusing probably because my english is not my language, and because i am not sure how a Java application works.
For running JSP on my local server, it is was easy, and I did need to know how it really works. I installed Tomcat server and Java SDK.
To run my application, i jsut need to type http://localhost:8080/myPage.jsp.
That description is not exact.
The server is running Tomcat with your application.
Your browser (not the application) connects to the server (tomcat) and the server (tomcat) runs your application and returns the result to the browser.
If i want to run the same myPage.jsp on my distant server, i would need probably to install something on my server?
www.mywebsite.com/myPage.jsp will not work just like that of course.
You need to install a number of things. At a minimum Tomcat and your application (the thing that runs inside Tomcat.) There is likely to be other requirements as well such as java and patches and perhaps a database server (if your application uses a database.)
So what do i need exactly to install on my server to run a JSP?
In fact, i am afraid if i install Tomcat on my server, the other applications will not work.What "other" applications?
Is Tomcat already installed on the server? Is there already other applications running on that server? Then yes you must install your application into Tomcat (not the server) such that it will not stop the other applications (in Tomcat) from running.
