Hello all,
I've been using the iText classes (v0.96) with the JDK1.4 for a week and I
think they're great. I have a question about the cell horizontal alignment
using the above method. I've searched the archives for
the .setDefaultHorizontalAlignment() method but didn't find my answer.
I've written a servlet to stream the results of a query using RtfWriter and
com.lowagie.text.table to the user as an rtf document. The problem I'm having
is the cell alignment of 1 column in the table does not change when I use
setDefaultHorizontalAlignment(). I saw a similar example of this in
Chap0510.java where it changes the cell alignment
using .setDefaultHorizontalAlignment(), but using the code below the cell
alignment for "db_grade" does not become centered, it stays left justified. In
the commented out code section below I found a way to make the cell centered,
but I'm wondering why setDefaultHorizontalAlignment() doesn't work.
Document document = new Document(PageSize.A4.rotate());
try
{
response.setContentType("application/rtf");
response.setHeader("Content-
Disposition","attachment;filename=\""+filename+"\"");
RtfWriter.getInstance(document, response.getOutputStream());
//Find the JDBC driver
Class.forName(sqlDriver); //establish the connection
conn = java.sql.DriverManager.getConnection(sqlURL);
stmt = conn.createStatement();
document.open();
if (reportType.equals("Parent"))
{
String db_student_name = "";
int db_stud_id = 0;
String db_grade = "";
String db_parent = "";
String db_telephone = "";
String db_address = "";
String db_email = "";
String db_relation = "";
HeaderFooter header = new HeaderFooter(new Phrase
(DateFormat.getDateInstance(FULL).format(today)), false);
header.setBorder(Rectangle.NO_BORDER);
document.setHeader(header);
document.add(new Paragraph(""));
document.add(new Paragraph("Teacher: "+teacherName, new Font
(Font.TIMES_NEW_ROMAN, 12,Font.BOLD)));
document.add(new Paragraph(courseName+",
Period "+periodName, new Font(Font.TIMES_NEW_ROMAN, 12,Font.BOLD)));
rs = stmt.executeQuery("SELECT DISTINCT stud_id, count
(stud_id) as count, ASTU_GRADE, ASTU_FIRSTNAME, ASTU_MIDDLENAME, ASTU_LASTNAME,
APRN_FIRSTNAME, APRN_LASTNAME, APRN_MIDDLENAME, STR_APRN_TELEPHONE,
