4.add html taglib

<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="h" %>

5. Add a form tag to JSP using tag lib

< action=" " onsubmit=" ">
< property="name">
< value="OK">
< / html:form>

6.Create New StrutsActionForm
*important: superclass should be org.apache.struts.validator.ValidatorForm

7. Make getters and setters for text field in JSP

(if u create a propety called 'name' you dont need to do this, bcoz
Netbeans defaultly create for String 'name and int 'number'
8.Create New StrutsAction
*important: Action path should be same as JSP forms action
(the Action path you give here can give in JSP)

9.edit validation.xml

< name="NameForm">
< property="name" depends="required">
< key="NameForm.name">
< /field>

< /form>

10.add 'NameForm.name' to properties file

11.Add these to JSP page
< formname="NameForm">
< /head>

< action="name" onsubmit="return validatenameForm(this);">

"Shared Library" functionality in NetBeans 6.1 beta

In new NetBeans 6.1-beta When creating a project you now get the offer to enable "sharable

libraries".
When enabling this feature you are asked to specify the location where the libraries should be

saved. By default it will suggest ..\libraries, which is a bit strange considering that it is

Setting up a JDBC Connection Pool

In order to specify how the web server allows an application to communicate with the database, we need to set up a database connection pool. A database connection pool is basically a group of reusable connections that a server maintains for a specific database. Web applications requesting a connection to a database obtain that connection from the pool. When an application closes a connection, the connection is returned to the pool.

In order to set up a connection pool on the server, a JDBC resource (also called a data source) must first be created. A JDBC resource provides applications with a connection to a database. Depending on whether you're using Tomcat or SJSAS, do the following:
