JAVA - Out Of Memory Error while writing Excel Cells in jxl

Question

I am using JXL to write an excel file of 50000 rows and 30 columns. My code looks like this:

for (int j = 0; j < countOfRows; j++) {

myWritableShe         


        

Answer 1

Is raising the memory available to the VM (with -Xms and -Xmx) not an option?

Answer 2

The JExcel FAQ has a couple of suggestions including Curtis' idea above.

If you don't mind the performance hit, you could use a temporary file instead of doing it all in memory.

WorkbookSettings s = new WorkbookSettings();  
s.setUseTemporaryFileDuringWrite(true);  
WritableWorkbook ws = Workbook.createWorkbook(new File("someFile.xls"),s);
