How to assign values to HTML fields (e.g. img src=“” with scriptlets Code Answer

Hello Developer, Hope you guys are doing great. Today at Tutorial Guruji Official website, we are sharing the answer of How to assign values to HTML fields (e.g. img src=“” with scriptlets without wasting too much if your time.

The question is published on by Tutorial Guruji team.

What I’m trying to do is to assign the value of a Scriptlet variable as the source for an image.

Here is the HTML in question:

    <div class="row">
    <div class="tab-content">
            <div class="tab-pane active" id="material">

          <ul class="thumbnails" id="hover-cap-3col">     

          <div id="myCarousel" class="carousel slide" data-interval="false">
              <!-- Carousel items -->
              <div class="carousel-inner">
                  <div class="active item">

                    rs = stmt.executeQuery("SELECT IMG_NAME FROM IMAGES WHERE IMG_NAME LIKE 'Material%'");

                    ResultSetMetaData rsmd = rs.getMetaData();

                    int columnCount = rsmd.getColumnCount();

                    if ( {

                        for (int i = 1; i < columnCount + 1; i++) {


                    for (String name : names) {

                        String url = "http://localhost:8085/assignment/GetImage?name=" + name;


                      <a href="http://localhost:8085/assignment/GetImage">
                      <div class="thumbnail">
                        <div class="caption"><h4>1</h4></div>
// RIGHT HERE ------>   <img src=<%url %> alt="ALT NAME">
                        <div class="caption-btm"><p>Material A</p></div>
                      <% } %>



At the place where I specify the source for the image (shown by the comment), it gives me the following errors:

  • Syntax error, insert “AssignmentOperator Expression” to complete Assignment
  • Syntax error, insert “;” to complete Statement

Obviously, I can’t assign the value to img src=”” in that way. Is there any way for me to use the Scriptlet value or should I just scrap it and move on?


If you want to write the value of an expression to the served page, you must use <%= expr %> construct instead:

<%=url %> 

This is called a JSP expression.
