hi Hassan,
Depending on your JVM-Platform new File("./personnel/mfleshman.jpg"); will
be relative to the current working directory, this maybe the bin directory
of your JDK or the bin directory of your app server etc,
ServletContext.getRealPath() is the correct approach for navigating
filesystems in web-app servers but note that it won't work if your running
your app from an un-extracted WAR file.
Try this...
<%String stmp_filelocation = new
String(application.getRealPath("/personnel/Eid.jpg"));
if(stmp_filelocation != null){%>
<table><tr><td>
<img src="personnel/Eid.jpg">
...
...
...
<%}%>
note that application object is the name Tomcat gives your servletContext,
it may be a different name depending on your web-container.
