hi,
i am facing a critical problem using WebPDFReports 1.0.
i used to generate quite a number of pdf daily, for each
generation,
it
may contain up to 80 pages. for the first generation, it always
works, but
if i continue to generate the pdf , it just gives No Instance
error.
Once
it occurs, i need to restart the webobject instance.
Sounds like the application is running out of memory. Check the
logs
for "OutOfMemory".
the other modules are working except the pdf component. is it
because
the
number of pages generated is too big ?
The problem is at least related to that. I can see from your code
below that the response is getting saved in the page cache, that
means
it will hang around consuming memory for quite some time. You will
need to return it in some other manner or override
Session.savePage()
to avoid this going into the page cache. I would also suggest
creating an EC on the PDF page and discarding it after use.
Chuck
please advice.
rgds,
koksiong
ps: the following are the code
public WOActionResults goPrintAction()
{
generateVehicleDeliveryListPDF nextPage =
(generateVehicleDeliveryListPDF)pageWithName
("generateVehicleDeliveryL
istPDF");
nextPage.setEc(ec);
nextPage.setATransactionArray(aTransactionArray.mutableClone());
PDFPage pdfPage = (PDFPage)pageWithName
("PDFPage");
HTML2PDFConvertor pdfConvertor = new
HTML2PDFConvertor();
pdfConvertor.createDocument("US
Letter",HTML2PDFConvertor.LandscapeOrientation);
pdfConvertor.setPaperSize(new PaperSize
(792,612));
pdfConvertor.setTopMargin(5);
pdfConvertor.setLeftMargin(5);
pdfConvertor.setRightMargin(5);
pdfConvertor.setBottomMargin(5);
pdfConvertor.setPrintsVerticallyCentered(false);
pdfPage.setConvertor(pdfConvertor);
pdfPage.appendComponent(nextPage);
return pdfPage;
}
