Question

i am using this method

<IMG SRC="basic.jsp">

for showing image in img tag this method work fine in tomcat but in weblogic server it is giving following error :

   The image “view-source:https://10.189.65.201:7003/UploadImg/getImage.jsp” cannot be displayed because it contains errors.

i know if i use Servlet with doGet() method instead a JSP psge it will work fine but why it is not working in this way is there any settings issue?

Answer 1

Any whitespace outside <% ... %> in the JSP file will also be printed and sent to the HTTP response.

So if you have e.g.

<% ... %>
<% ... %>
<% ... %>

then effectively 2 newlines will also be sent to the reponse. This corrupts the binary format of the image.

You’d basically need to replace it by

<% ... %><% 
   ... %><% 
   ... %>

to prevent those newlines being printed to the response (and make sure that there’s no trailing newline, either).

Or, better, just use a servlet. JSP is meant to generate text based content like HTML, not binary based content like images. Something with using the right tool for the job.
