Hi all,
I have an application deployed on tomcat. The application is supposed to generate an Image file (myImage.png).

I want to display this image on a JSP page. When i run the application the image file is not generated in any of tomcat folder hierarchy.

The way i have specified the output path for the image is



How do i specify path so that this image is output in my tomcat/webapps/app folder?

Thank you in advance.
Regards,
Gaurav

If the image is not under your webapp's directory structure, you'll need to write a servlet that streams the image to the browser.

This is not difficult.
I have an example app that does this.

Look for SimpleStream.

In that app, I'm using getResourceAsStream to read image files under the webapp's directory structure but hidden from the web under WEB-INF.

In your case, you will have to use java.io.FileReader to read your image files but, otherwise, everything should be the same.
