Hi,
** We are doing the following:
We are generating a PDF which contains a table with
column width 100.
But the data(extracted from the Database) to be
inserted in that column contains more than 2000
characters.
As a result, we get an "Out of Memory Exception - Java
Heap Space".
i)But if we insert small amount of data in the same
column(width remaining same) , it works fine.
ii)Also, when we increase the width of the column to
150(no. of characters being same) , it too works fine.
We have attached the XML file (PDFTableView.xml) and
the code(PDFTableView.java) where we are getting the
above mentioned exception.
** How are we doing it ?
1) Draw a table with column width given in
xml(NSWidthBinding).
2) for(noOfRows)
{
for(noOfColumns)
{
Create a dataObject for each Column;
Fetch data (from column of the table in
Database)
in dataString;
Insert dataString in dataCell;
Add dataCell to dataTable;
}
}
I feel that the dataString.length() is very large and
does not fit in the dataCell -- as a result we are
getting the "Out Of Memory Exception!!"
I came to this conclusion because if the
dataString.length() is SMALL OR the column width is
LARGE , then it works fine..
So, I feel the exception has something to do with the
size constraint of the Cell(width of the column).
Please let us know if we need to follow any guidelines
for setting up the fonts & column widths of the cell
or do let us know if there is any generic fix for the
above issue for all font types, styles and sizes
Thanks & Regards,
Vijay.
