You can use a servlet that print the photo on your page.
Here is the needed code:
<li class="info">
<Admin:label styleClass="desc" key="user.photo"/>
<img src="<c:url value="/admin/userPhoto?id=${user.id}"/>"
height="150" width="150"/>
</li>
For the servlet:
try {
userId = Long.parseLong(_userId);
UserPhoto userPhoto =
userPhotoManager.getUserPhotoByUserId(userId);
_userPhoto = userPhoto.getPhoto();
// flush it in the response
httpServletResponse.setHeader("Cache-Control", "no-store");
httpServletResponse.setHeader("Pragma", "no-cache");
httpServletResponse.setDateHeader("Expires", 0);
httpServletResponse.setContentType("image/jpeg");
ServletOutputStream responseOutputStream =
httpServletResponse.getOutputStream();
responseOutputStream.write(_userPhoto);
responseOutputStream.flush();
responseOutputStream.close();
} catch (NumberFormatException nfe) {
}
So your userPhotoManager can fetch the photo either from a database or from
a filesystem.
Hope this helps !
