professor what kind of changes do we need to make to the class design to add the profile pictures?
do we need to make any changes to class  for the homework ?

professor i am getting this error
 

HTTP Status 500 - Request processing failed; nested exception is java.lang.ClassCastException: org.springframework.web.multipart.commons.CommonsMultipartFile cannot be cast to java.io.File

my controller looks like this... why am i getting this error? my commons io and file upload dependencies have also been included...

byte[] image = new byte[(int) ((File) file).length()];

try {

FileInputStream fileInputStream = new FileInputStream(file.getName());

fileInputStream.read(image);

fileInputStream.close();

} catch (Exception e) {

e.printStackTrace();

}

professor i am using ImageIO, i am able to retrive the image data via controller/userDao then i use the Image io to convert back to image(jpg in this case)  my question is can i pass the file to jsp to display as image ? currently it only displays image.jpg and not the image as i did a

models.put("outputFile", outputFile);

You can't just "write" an image to a JSP. A JSP is basically an HTML page (with some dynamic content), and the only way to include an image in HTML is to use the <img> tag. The src attribute of <img> should point to some controller that returns the image (like in the file download example).

I don't see what the difficulty is. In your JSP you would have something like <img src="getImage?lawyerId=${lawyer.id}" />.

professor i was wondering for getImage will it be a controller or a method inside lawyer controller?

created a controller servlet it working now... thank u

Professor whats the best way to access/point-to files within the  spring directory?

For the default lawyer image.. i dont know if i am following the right approach but i am putting a default image called
default.jpg on my WEB-INF/image folder and i am trying to read this and convert into byte[] when a lawyer does not upload an image...

the problem here i am facing is that spring is not able to identify the path to read from the folder..
i've tried
String fileLocation = resp.getServletContext().getRealPath("/src/main/webapp/WEB-INF/images/");
which gives me a path/file not  found error

as well as
InputStream in = getClass().getResourceAsStream("/default.jpg");
which gives me a null pointer error

I'd put /image in WebContent instead of WEB-INF, and use a <c:if> in the JSP to either load the user image through a controller or the default image by direct link (e.g. <img src="image/default.jpg">). It's easier to program and gives better performance because the browser can cache the the image for all the lawyers who didn't upload their own images.

In your approach the correct path to getRealPath() is "/WEB-INF/image/default.jpg". getReadPath() converts a path relative to the application context to a path on disk.
