Re: Problems with tutorial Web Application for JDBC access

[Tim McConnell <ti...@gmail.com>]

Hi Tero, I was able to duplicate the error you're seeing. However, you have to be 
a little careful specifying the image location and image name when using the 
Image Upload jsp. More specifically, it wants you to enter the full path + the 
filename + extension in the "Location of the Image(full path)" entry field. The 
"Name of the Image(Unique Name)" entry field then is then used to uniquely 
identify that image in the system database. So in your case you might want to use 
this:

Location of the Image(full path):	c:\app\FILENAME.EXT
Name of the Image(Unique Name):	  FILENAME

If you do that you'll find that it uploads correctly. Then you can use the Image 
Download jsp to view what you've uploaded using the unique name you specified 
above. So in your case you would use: For example:

Name of the Image: 	FILENAME

Try that and let me know how it goes. BTW, I noticed a couple errors in the 
documentation for this tutorial, which you probably noticed as well.  I'll clean 
those up tomorrow. Thanks
