Hi Richard,
I tried to use the java.io.File.exists() method, but doing the following.
try
{
File imageFile = new File("./personnel/mfleshman.jpg");
if(imageFile.exists() ){ %>
file exists.
<table><tr><td>
<img src="personnel/Eid.jpg">
......
......
}catch()....
Above code never finds the file. And now you have mentioned about
ServletContext.getRealPath() method so I am thinking that my path
which I have given for the file is not correct /unrecognized by java .
Could you please give me an example or please explain more about
ServletContext.getRealPath() method.
thanks much
Hassan

Hassan,
Use the java.io.File.exists() method. You will also probably have to use
the ServletContext.getRealPath() method to construct the path to the actual
image file.
As a suggestion, I wouldn't recommend putting the images in the jsp
directory. They should be put in a separate directory. If you want to
hide them from the public, put them under the WEB-INF directory and have
them be returned by a servlet or else store them as BLOBs in the DB.
Regards,
Richard
