How to ignore the angle braces from being removed.

When a text field input contains the symbols <> together and submitted,it gets saved.

But,when the requested JSP page that must contain the field with <> together is loaded,it does not get displayed.The following example will make it easy to understand.
Suppose if a form text field input is <trial> and submitted,it gets saved.
But,when that JSP page is requested,it does not get displayed.Can I know the reason?

The reason is invalid markup. The characters need to be html-escaped. Using the <c:out> tag to emit the value will automatically escape any such characters.

The reply is not clear.

The form contains a ProductName field.

<td   >ProductName</td>
<td> 
<input type="text" name="productName" value="" class="smallData">
<br>

Text in the form given as "<text>" and saved.

When another JSP is called,which requests for the ProductName,it returns nothing.So,kindly provide clarity on where this <c:out> tag should be used.
