So I finished coding my application to rotate TIFF images which required JAI to manipulate the TIFFs.
It works fine when working under Eclipse, but whenever I build a fat jar for the library and then create one implementing that (per http://fjep.sourceforge.net/fjeptutorial.html), when I do the java -jar Push.jar \path\to\dir, it runs up until it hits the part where it is compressing and saving:
TIFFImageWriterSpi tiffspi = new TIFFImageWriterSpi();
ImageWriter writer = tiffspi.createWriterInstance();
//Iterator<ImageWriter> iter = ImageIO.getImageWritersByFormatName("TIFF");
//ImageWriter writer = iter.next();
ImageWriteParam param2 = writer.getDefaultWriteParam();
param2.setCompressionMode(ImageWriteParam.MODE_EXPLICIT);
param2.setCompressionType("LZW");
param2.setCompressionQuality(0.0f);
File fOutputFile = workArea[i];
ImageOutputStream ios = ImageIO.createImageOutputStream(fOutputFile);
writer.setOutput(ios);
if (frontPage == 1)
{
writer.write(null, new IIOImage(pg1, null, null), param2);
writer.writeInsert(-1, new IIOImage(pg2, null, null), param2);
}
else if (frontPage == 2)
{
writer.write(null, new IIOImage(pg2, null, null), param2);
writer.writeInsert(-1, new IIOImage(pg1, null, null), param2);
}
remaining = remaining - 1;
if (remaining > 0)
System.out.println(remaining + " remaining.");
else
System.out.println("Done.");
It blows up on the first line of that section with the message:
Exception in thread "main" java.lang.IllegalArgumentException: vendorName == null!
....rest of stack trace.
