Hello,
Thanks for the sample code, I got it, now I have started running into
problems.
I used the HelloWorld.jsp page in my application server to test. generating
a PDF from jsp page. Though u mentioned the problems associated with use of
JSP page. I have to use it because of limitations of the application and
technology we are using. I cannot use servlets -not possible.
I am copying my code below, I tried to compile my JSP page and I see that
the client browser my browser is IE.6.0 and FireFox 1.0.7 (both are failing)
to generate a PDF. In IE I see that the client is calling Acrobat Reader but
I get a blank screen and the following message
* File name does not begin with %PDF-*
But in FireFox its just a blank screen.
Sometimes when I tried to modify small pieces of code to test. I also got
java.io exception and said *document does not have pages*. I used the same
logic as tutorial hello world code.
My JSP is located in Oracle Apps and its powered by Oracle Apache server. I
would appreciate if you can give me an approach or point me to an
example, to resolve this issue. I have to generate a PDF of some data
available to me in the session. I am even ok with the approach of creating a
temp.pdf on the server for every user , I can open a file to display it to
the user, delete it when he closes the pdf, if so how do i do? any examples
available? i tried searching the archives could not come across the one i
need. Thanks for your help in advance. I need to get through the first step,
and I am sure everything else will be easy after, I wanna generate a pdf
from Helloworld.jsp.
Here is my code -- helloworld.jsp- same as what is available in the itext
tutorial
<%@ page import="java.io.*"%>
<%@ page import="com.lowagie.text.*"%>
<%@ page import="com.lowagie.text.pdf.*"%>
<%
try{
response.setContentType("application/pdf");
Document doc = new Document();
java.io.ByteArrayOutputStream  .html>java.io.ByteArrayOutputStream java.io.ByteArrayOutputStream .java.html>' border=0> buffer = new java.io.ByteArrayOutputStream .html>java.io.ByteArrayOutputStream java.io.ByteArrayOutputStream .java.html>' border=0>();
PdfWriter.getInstance(doc, buffer);
doc.open();
doc.add(new Paragraph("Hello World"));
java.io.DataOutput ot = new java.io.DataOutput Stream(
response.getOutputStream());
byte[] bytes = buffer.toByteArray();
response.setContentLength(bytes.length + 100);
for( int i = 0; i < bytes.length; i++ ) {ot.writeByte( bytes[i] ); }
doc.close();
}
catch(Exception e){
e.printStackTrace();
}
