--------------------------------------------
Hi Tilman,Hi Tilman,
I create PDPageContentStream in generateTransactionReceiptPDFPage() and pass
that to called methods downstream. In the code we call beginText() many times
before we enter quesAnsRightAlign() where we got nullpointer.
This is how we create PDPageContentStream object. receiptDetail.setTexty(800f);
PDRectangle rec = new PDRectangle(218, 808); PDPage page = new PDPage(rec);
contentStream = new PDPageContentStream(document, page);
Code snippet where we call quesAnsRightAlign(). You can see we call beginText()
method before entering to that method and it worked fine. Thats why I dont
understand why it fails randomly. It is like once in 500 transaction it fails.
contentStream.beginText(); contentStream.setFont(PDType1Font.HELVETICA,
fontSize); receiptDetail.setTexty(receiptDetail.getTexty()-lineSpacing);
contentStream.newLineAtOffset(textx+10, receiptDetail.getTexty());
contentStream.showText("Sold by: "+" "+soldby); contentStream.endText(); //DDF
if(RetailUtils.isNotNull(devicesDetail.getSku()) &&
RetailConstants.GIVEBACK.equalsIgnoreCase(devicesDetail.getSku())) \{
if(RetailUtils.isListNotNull(devicesDetail.getQestionAnsDetailsList())) {
if(receiptDetail.getTexty() <10) { contentStream = newPage(contentStream,
document, receiptDetail); } contentStream.beginText();
contentStream.setFont(PDType1Font.HELVETICA_BOLD, fontSize);
receiptDetail.setTexty(receiptDetail.getTexty()-lineSpacing);
contentStream.newLineAtOffset(textx, receiptDetail.getTexty());
contentStream.showText("Device Evaluation:"); contentStream.endText();
for(QestionAnsDetails qna : devicesDetail.getQestionAnsDetailsList()) \{
receiptDetail.setTexty(receiptDetail.getTexty()-lineSpacing);
quesAnsRightAlign( qna.getQuest(), qna.getAnswer(), receiptDetail,
contentStream, document); } } }
public PDPageContentStream quesAnsRightAlign(String txtRight, String txtLeft,
RmsReceiptDetail receiptDetail, PDPageContentStream contentStream, PDDocument
document) \{ RetailLogger.enterScope(TRACE_TAG + " quesAnsRightAlign()"); try {
if(receiptDetail.getTexty() <10) { contentStream = newPage(contentStream,
document, receiptDetail); } contentStream.beginText();
contentStream.setFont(PDType1Font.HELVETICA, fontSize); //float text_width1 =
(PDType1Font.HELVETICA.getStringWidth(txtRight) / 1000.0f) * fontSize;
contentStream.newLineAtOffset(textx+75, receiptDetail.getTexty());
contentStream.showText(txtRight); contentStream.endText();
contentStream.beginText(); contentStream.setFont(PDType1Font.HELVETICA,
fontSize); float text_width = (PDType1Font.HELVETICA.getStringWidth(txtLeft) /
1000.0f) * fontSize; contentStream.newLineAtOffset(receiptWidth - (text_width+
textx), receiptDetail.getTexty());//Migrating to PDF Print fix
contentStream.showText(txtLeft); contentStream.endText(); }catch(Exception e)\{
RetailLogger.error("Exception in "+ TRACE_TAG+" quesAnsRightAlign() --> " +
e.getMessage(), e); } RetailLogger.exitScope(TRACE_TAG + "
quesAnsRightAlign()"); return contentStream; }
In the next sample log I got, it happened at a different place. So its random.
