Subject: Re: [iText-questions] Problem about using JSP to report PDF
withJapanese font
Dear Bruno Lowagie,
I am very glad when it can show Japanese Text but now I have more problems:
1) When I include files in JSP file that have report PDF using iText.
ex: <%@ include file="tools.jsp"%>
OR
When I change the following code :
<%@
page import="java.io.*,
com.lowagie.text.pdf.PdfWriter"
%><%
// steps to output pdf file using iText
%>
to
<%@
page import="java.io.*,
com.lowagie.text.pdf.PdfWriter"
%>
<%
// steps to output pdf file using iText
%>
It always get errors:
org.apache.jasper.JasperException: getOutputStream() has already been called
for this response
Now you know why you shouldn't use JSP to generate PDFs. The construct:
<%@
page import="java.io.*,
com.lowagie.text.pdf.PdfWriter"
%>
<%
// steps to output pdf file using iText
%>
will introduce an extra CRLF in the response stream. It's very easy to
introduce unwanted CRLF and spaces in JSP that don't matter in HTML but are
deadly in PDF.
2) When I write directly Japanese text into JSP file. It always show wrong
font!
But In Java application, It is OK.
ex:
document.add(new Paragraph("\u8ab0\u3082\u77e5\u3089\u306a\u3044",
font));
-> It is OK.
document.add(new Paragraph("Hello by Japanese
(こにちわ！). ",
font));
-> It is not OK.
My project is using encoding: Shift_JIS (MS932)
JSP are compiled into servlets using some default encoding in the appication
server. You'll have to set an explicit encoding in your application server
if it's not MS932, that is, in every application server where the JSP is
deployed. This problem doesn't occur in servlets because they are compiled
in your development environment and will work everywhere.
Please help me how can I solve that problems.
Use servlets instead of JSP.
Paulo
Best regards,
Bang

I'm glad it works now.
I easily lose my patience with people
that forget to set the CLASSPATH.
It's in my nature...

When were taught how to write JSP files,
I hope you were told that JSP is to be
used to produce HTML or TXT files, and
that you shouldn't use JSP to produce
binary files such as JPG, PDF, GIF,...
This advice is given so that you can avoid
the many troubles that are inherent to JSP
and the *preservation of non-ASCII bytes*.
If you like stress or if you're a JSP guru,
you can ignore this advice. It's up to you ;-)
best regards,
Bruno
