data_dir = File.dirname(File.dirname(File.dirname(File.dirname(__FILE__)))) + '/data/'
# Open a pdf document.
doc = Rjb::import('com.aspose.pdf.Document').new(data_dir + "input1.pdf")
# Get document information
doc_info = doc.getInfo()
doc_info.setAuthor("Aspose.PDF for java")
doc_info.setCreationDate(Rjb::import('java.util.Date').new)
doc_info.setKeywords("Aspose.PDF, DOM, API")
doc_info.setModDate(Rjb::import('java.util.Date').new)
doc_info.setSubject("PDF Information")
doc_info.setTitle("Setting PDF Document Information")
# save update document with new information
