In JavaServer Pages (JSP) technology, a scriptlet is a piece of Java-code embedded in the HTML-like JSP code.

The scriptlet is everything inside the <% %> tags. Between these the user can add any valid Scriplet i.e. any valid Java Code.

Scriptlets are executed at request time, when the JSP engine processes the client request. If the scriptlet produces output, the output is stored in the out object, from which you can display it.

What is the difference between script and scriptlet?

"script" is an HTML tag used to include JavaScript on a web page. Example: &lt;HTML&gt; &lt;body&gt; &lt;script type="text/javascript"&gt; document.write("hi there"); // javascript interpreted by the browser &lt;/script&gt; &lt;/body&gt; &lt;/HTML&gt; "Scriptlet" is a JSP construct used to include Java in a JSP page. Example: &lt;HTML&gt; &lt;body&gt; &lt;% // this is a scriptlet response.getWriter().write("hi there"); // Java executed on the server %&gt; &lt;/body&gt; &lt;/HTML&gt; Here the result (an HTML document with the text "hi there") is the same in both cases, but the mechanisms are different - Javascript runs in the browser (any browser), while the JSP scriptlet is executed on the server and needs a server with JSP support.

How do you call javascript function from scriplet?

To call a JavaScript function from a JSP (JavaServer Pages) scriptlet, you can use the &lt;script&gt; tag within the scriptlet code. For example: &lt;% out.println(&quot;&lt;script&gt;myJavaScriptFunction();&lt;/script&gt;&quot;); %&gt; This code dynamically generates a &lt;script&gt; tag that calls the specified JavaScript function when the JSP is rendered in the browser. Ensure that the JavaScript function is defined and accessible in the client-side context.
