hi

i am new to JAVA.

I am writing code for a project which requires me to convert an image to grayscale. For which i am using this code

public static BufferedImage convertToGrayscale(BufferedImage source) {
     BufferedImageOp op = new ColorConvertOp(
      ColorSpace.getInstance(ColorSpace.CS_GRAY), null);
     return op.filter(source, null);
}


It works well so long as i am in development mode (using netbeans), but when i build and try to run the .jar, i get the error that PYCC.pf can't load.

From what i ahve read around apparently this file is delibrately not included in JRE although its there in the JDK.

Q: How to i include this file for distribution with my 'compiled' .jar ?

Which version of java are you using? There was a bug with this in java 1.4:

In 1.6 the file is in the jre.

Usually applications state system requirements in the readme file.

You can also check the version of java at application start in the main method and if the version is not 1.6 display instructions on how to download 1.6 or how to fix the missing jar bug.
