getImageWritersByFormatName doesn't give proper values

Question

Iterator<ImageWriter> writers = ImageIO.getImageWritersByFormatName(TIFF_FORMAT); 
if (!writers.hasNext()) {
    throw new RuntimeException(JAI_IMAGE_WRITER_MESSAGE);
}

net.sourceforge.tess4j.TesseractException: java.lang.RuntimeException

Need to install JAI Image I/O package. Exception is thrown because of hasNext().

The same web application works in my mac machine, but not on an ubuntu machine. I am using tomcat server. Any help?

Answer 1

Thanks! I figured out the mistake myself.. i had to set the classpath to the jai_imageio.jar file in tomcat/bin/setenv.sh
