How to run jsp using javabean class in tomcat

hello all,
i have bean class placed in classes folder of tomcat and placed jsp and html in root directory. i am not able to run it , if i have do any setting in web.xml, pls let me know from u

No XML required, but you must put the class into a package.
Packages are folders with some files that identify whats in them, so you will end up with something like
yourWebbApp/classes/yourPackage/yourClass

How to run jsp using tomcat server?

hai friends,
i'm using jsp for my application and for that i'm using tomcat server.
i was runing my jsp files like this
http://localhost:8080/examples/jsp/myapp/index.jsp but instead of this
i need to run my jsp files like this
http://localhost:8080/myapp/index.jsp
what r the changes that i should do in tomcat installation to run myapplication in such a way.
thanks in advance

you need to redefine the server root...
for that do the following...
copy all the directory tree rooted at
JAKARTA-HOME/webapps/ROOT/examples/jsp/myapp/ to
JAKARTA-HOME/webapps/ROOT/myapp/
-OR-
in the server.xml, search for "Tomcat Root Context" and un-comment the code defining Root Context...
change the docBase value from "ROOT" to "ROOT/examples/jsp"
that shud help...

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.

The deployment problem in JSP using JavaBean

Hi there,
I followed the descriptions in Writing Enterprise Applications with
Java 2 SDK, Enterprise Edition tutorial to build a set of programs to run JSP with JavaBean, and I also followed the steps in creating new WAR file, but some how it wouldn't work after I deployed them. I run the JSP in IE and got a message like this:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 20 in the jsp file: /1bonus.jsp
Generated servlet error:
c:\j2sdkee1.3.1\repository\orbit\web\JSPRoot\$1bonus$jsp.java:63: Class org.apache.jsp.JBonusBean not found.
JBonusBean jbonus = null;
^
I used the deploytool to create the WAR file, and after I added the 1bonus.jsp, I also added JBonusBean into the WAR file. I found 1bonus.jsp was added into the WAR file, but there's no JBonusBean appeared under the WAR file.
Could you please tell me is there anything wrong?
Thanks for your time.
Regards,
Eric

I think you have not imported 'BonusBean' in your jsp. Code this line in your jsp at the top.
<%@page import="BonusBean" %>

How to run jsp program

is i can able to run my jsp program by using appache server..

To get JSP working in Apache HTTP Server you have to install Apache Tomcat.
You can either choose to run JSP's solely on Apache Tomcat, or to use mod_jk2 to link Apache HTTP Server with Apache Tomcat so that the Apache HTTP Server can forward the JSP requests to the Apache Tomcat engine, because the Apache HTTP Server really doesn't know how to compile/run JSP's.

How to run JSP/Servlet in AIX?

how to run JSP/Servlet in AIX?
I am no ideas about it,
can anyone tell me?
what webserver i should use?
have to install JDK?

The only successful way that I have been able to run servlets in an AIX environment is with the IBM Http Server (specific version of Apache)/WebSphere combination, with WebSphere as the servlet engine. I have tried (unsuccessfully) to use JRun and Apache in AIX environment, but could never get JRun to function properly.

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.
