Java – propertynotfoundexception when using JSTL with Boolean value

• Java

I have a filebean that renames Boolean variables It has the following code

public class FileBean {

    private boolean renamed;

    public boolean isRenamed() {
        return renamed;
    }

    public void setRenamed(boolean isRenamed) {
        this.renamed = isRenamed;
    }   
}

I have passed its object to JSP using the request object (consider filedetail is the name of the request attribute) My JSP contains the following code

<tr>
  <td>${fileDetail.isRenamed}</td>
</tr>

Using this, I get lower than runtime exceptions on JSP

org.apache.jasper.JasperException: javax.el.PropertyNotFoundException: Property 'isRenamed' not found on type <mypackage>.FileBean  
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:549)
        org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:470)
        org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:390)
        org.apache.jasper.servlet.JspServlet.service(JspServlet.java:334)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:722)

Please suggest a solution

Thank you in advance

Solution

You need to use the attribute name / field name If it is a boolean type, JSTL looks for isrenamed () based on the POJO convention

Example:

<td>${fileDetail.renamed}</td>
