Please help.

I'm using PdfContentByte to position text (which are variables filled from a
list) on my screen. They are basically name plates with two per page.
Problem is only the last page is showing up ... its like the contentbyte is
overwritten... how do i stop this from happening. If I take away the new
page command the loop works fine, just writes on top of itself on one page.
When I have the new page in there it does crazy stuff... like blank pages
and even one page that is set at zoom 4444% or something.

Sample code:

for (int i=0; i < students.size(); i++)

{

//Grab student

StudentPerson student = (StudentPerson) students.get(i);

String lname = student.getLastName();

String fname = student.getFirstName();

String service = student.getServiceComponent()

String borderTop= "__ ____ ____ ____ ____ _____";

String borderBottom = "BLABLABAHABLAHABALHABLA";

PdfContentByte cb = writer.getDirectContent();

BaseFont bf = BaseFont.createFont(BaseFont.HELVETICA_BOLD,
BaseFont.CP1252, BaseFont.NOT_EMBEDDED);

cb.beginText();

if(topRecord == true)

{

sealDod.setAbsolutePosition(25, 350);

sealDod.scaleAbsolute(200, 200);

addElement(sealDod);

cb.setFontAndSize(bf, 24);

cb.showTextAligned(PdfContentByte.ALIGN_CENTER, fname,
500, 425, 0);

cb.showTextAligned(PdfContentByte.ALIGN_CENTER, lname,
500, 375, 0);

cb.showTextAligned(PdfContentByte.ALIGN_LEFT, service,
25, 350, 0);

cb.setFontAndSize(bf, 18);

cb.showTextAligned(PdfContentByte.ALIGN_CENTER,
borderTop, 475, 350, 0);

cb.showTextAligned(PdfContentByte.ALIGN_CENTER,
borderBottom, 475, 325, 0);

topRecord = false;

}

else

{

sealDod.setAbsolutePosition(25, 50);

sealDod.scaleAbsolute(200, 200);

addElement(sealDod);

cb.setFontAndSize(bf, 24);

cb.showTextAligned(PdfContentByte.ALIGN_CENTER, fname,
500, 125, 0);

cb.showTextAligned(PdfContentByte.ALIGN_CENTER, lname,
500, 75, 0);

cb.showTextAligned(PdfContentByte.ALIGN_LEFT, service,
25, 50, 0);

cb.setFontAndSize(bf, 18);

cb.showTextAligned(PdfContentByte.ALIGN_CENTER,
borderTop, 475, 50, 0);

cb.showTextAligned(PdfContentByte.ALIGN_CENTER,
borderBottom, 475, 25, 0);

topRecord = true;

}

cb.endText();

//Every 2 records create a new page

if(i % 2 == 1)

{

//Then create new page

//newPage();

}

}
