Create Bootstrap template to be used on all JSP pages of your Java app, implementing only the "content / content"

You can also use taglibs, just add in the WEB-INF folder a folder for the content you want to create and then add small files with the tags themselves:

• Create the WEB-INF / tags folder:
• Inside it creates a file called header.tag

Add the code you want to use, for example:

<%@ attribute name="urlImage" required="true"%>
<nav class="navbar navbar-default">
   <div class="container-fluid">
      <div class="navbar-header">
         <a class="navbar-brand" href="#">
           <img alt="Brand" src="${urlImage}">
         </a>
      </div>
   </div>
</nav>

And in your jsp use it as follows:

<%@ taglib tagdir="/WEB-INF/tags" prefix="tag"%>
<tag:header urlImage="url/da/imagem"/>

And for others it's the same process.

I solved the problem as follows:

1: The excerpts that would not change, for example the Menu, created a file called menu.jsp, and left only the menu code in the file.

On the home.jsp page, I imported the menu.jsp page.

menu.jsp: (Generate a blank file and just write the code of your menu), as it will be assigned to home.jsp.

home.jsp: (Here you should have the full header of a JSP)

Inside the body tag:

jsp:include page="template/menu.jsp"
