最近工作中遇到不少问题。总结一下。这段代码主要功能是将一个生成JSP页面转发成PDF输出到页面 需要利用ITEXT String html = ServletUtils. forward(request,response, "/WEB-INF/jsp/depot/print/jhd.jsp"); //转发请求到jsp，返回解析之后的内容而不是输出到浏览器 //System.out.println(html); byte[] pdf = PDFUtils. html2pdf(html); response.setContentType( "application/pdf"); response.setHeader( "Content-Length",String. valueOf(pdf. length)); response.setHeader( "Connection", "keep-alive"); response.setHeader( "Accept-Ranges", "none"); response.setHeader( "X-Frame-Options", "DENY"); OutputStream out = response.getOutputStream(); out.write(pdf); out.flush(); public class

Exception referring # START NON-TRANSLATABLE while working with java itext and IBM i RPG ILE

问题 working with java itext library, with a very simple test. Code passes but when closing document, it fails due to null pointer exception with java.lang.String.compareToIgnoreCase. It happens while embedding itext java code into IBM i RPGIV code. Not sure yet if it is a JNI/RPGIV conversion problem (utf8 should be converted to EBCDIC native charset) or a proper itext issue. It would help if any itext developer could confirm me if it could be a typical itext issue or not sounds like that,
