Image inside war not displayed on JSP

Question

I know, that there are already several of similar questions but none of them fix my problem. I have a simple JSP

<!DOCTYPE html>
<html>
   <head>
      <meta charset="UTF-8">
      <title>Home Page</title>
   </head>
   <body>    
      <jsp:include page="_menu.jsp"></jsp:include>    
      <h3>Home Page</h3>   
      <table>
            <tr>
               <td>aha</td>
            </tr>
         </table>
         ${data.image}      
         <img src="images/wappen.jpg"/>   
         <img src="/images/wappen.jpg"/>   
         <img src="../images/wappen.jpg" alt=""/>   
   </body>
</html>

none of the images is displayed. JSP is located in war in WEB-INF/views jpg is located in war in folder images.

Directory structure:

-WebContent
 - images (here are my jpgs)
 - META-INF 
 - WEB-INF 
   - lib 
   - views (here are my jsps located)

The jsp is called via webServlet:

RequestDispatcher dispatcher = this.getServletContext().getRequestDispatcher("/WEB-INF/views/homeView.jsp");
dispatcher.forward(request, response);

Maybe [this](https://stackoverflow.com/questions/23195317/accessing-resources-from-jsp-inside-web-inf) and also [here](https://stackoverflow.com/questions/30321952/read-the-file-from-webcontent-images-instead-of-web-inf) might help you . — Swati, Apr 15 '19 at 13:46

I don't know if it's the correct way, but at least I found a solution:

create a webservlet to handle the context Images:

retrieve the requested image
build the absolute filename of the image
load the image from disk
return as response

import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.FileInputStream; import java.io.IOException; import java.lang.invoke.MethodHandles;

import javax.servlet.ServletException; import javax.servlet.ServletOutputStream; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;

import org.slf4j.ext.XLogger; import org.slf4j.ext.XLoggerFactory;

@WebServlet(urlPatterns = { "/Images/*" }) public class DisplayImageServlet extends HttpServlet { /** holds the logger */ final XLogger logger = XLoggerFactory.getXLogger(MethodHandles.lookup().lookupClass());
```
private static final long serialVersionUID = 1L;
```
public DisplayImageServlet() { super(); }

@Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { HttpServletRequest req = (HttpServletRequest) request;
```
  String realRootPath = request.getServletContext().getRealPath("");
    String servletPath = req.getServletPath();
    String image = req.getRequestURI();
    String pathInfo = request.getPathInfo();

    logger.debug("realRootPath = " + realRootPath);
    logger.debug("servletPath = " + servletPath);
    logger.debug("image = " + image);
    logger.debug("pathInfo = " + pathInfo);
    String imageRealPath = realRootPath +servletPath+pathInfo;

    logger.debug("imageRealPath = " + imageRealPath);
    response.setContentType("image/jpeg");  
    ServletOutputStream out;  
    out = response.getOutputStream();  
    FileInputStream fin = new FileInputStream(imageRealPath);  

    BufferedInputStream bin = new BufferedInputStream(fin);  
    BufferedOutputStream bout = new BufferedOutputStream(out);  
    int ch =0; ;  
    while((ch=bin.read())!=-1)  
    {  
        bout.write(ch);  
    }  

    bin.close();  
    fin.close();  
    bout.close();  
    out.close();  
```
}

@Override protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { logger.debug("doPost"); doGet(request, response); }

}
