The type there is the class of the object. It simply means that the specific bean is of type xxx.yyy.Z.

Hi, 
 
I was reading as below 
 
 

<blockquote>
jsp:useBean as in &nbsp;MVC 
 
AS JSP page should not create the objects 
 
servlet(not JSP page), should create all the data objects. To ensure JSP page will not create 
objects, we should say like below. 
&lt;jsp:useBean ... type=&quot;package.Class&quot; scope=&quot;request&quot; /&gt; 
 
instead of 
 
&lt;jsp:useBean ... class=&quot;package.Class&quot; scope=&quot;request&quot;/&gt; 
 
Note: 
scope is not used in MVC (Model 2) architecture 
 
 
&lt;jsp:useBean id=&quot;...&quot; type=&quot;...&quot; /&gt; 
 
 
 
 
JSP should never modify the objects 
&nbsp; 
&nbsp;So say jsp:getProperty 
but not 
 
jsp:setProperty. 
&nbsp; 
 
 
&nbsp; 
 

</blockquote>
 
 
 
I have not clearly understood what it means. How 'type' and 'class' are different. When to use use which one and advatages, disadvantages of using each one of them. 
 
Please advise. 
 
Any links resources ideas highly appreciated. Thanks in advance

jsp:useBean as in  MVC  compared to standaalone JSP

Java Enterprise Edition (Java EE) is a specification defining a collection of Java-based server and client technologies and how they interoperate. Java EE specifies server and client architectures and uses profiles to define technology sets targeted at specific classes of applications. All Java EE profiles share a set of common features, such as naming and resource injection, packaging rules and security requirements.

Java EE

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.

Java

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
