Servlet giving error java.lang.NoClassDefFoundError

Question

I am using the following code in a servlet of my app

java.awt.Image awtImg = java.awt.Toolkit.getDefaultToolkit().createImage(str1);

When I run

Answer 1

To use AWT classes in a server side application, I believe you need to run in "headless" mode. Change your servlet container's startup to include:

-Djava.awt.headless=true

(Or set the system property within your own code if you really have to.)

You might also want to consider using an alternative imaging library - either a third-party one or the javax.imageio package.
