<% //String servletPath=request.getServletPath();// int end =servletPath.lastIndexOf('/')+1;
//System.out.println(end);
//String photoPath=servletPath.substring(0,end);
String path=request.getRequestURI();
//System.out.println(path);
int end =path.lastIndexOf('/')+1;
String photoPath=path.substring(0,end);
System.out.println(photoPath);
%>
<script language="javascript">
function showPic(obj) {
var o = document.getElementById("showimg");
var b = document.getElementById("photoPath");
var i=obj.value.lastIndexOf('s')+2;
var j=obj.value.length;
//var a = document.image.value;
//var int j=a.length;
//var i=a.lastIndexOf('s')+2;
var filename=obj.value.substring(i,j);
o.src=b.value+"images/"+filename;
o.style.display="";
o.border=1;
}
</script>
