Hi
I'm using these componentes (tFileExcelWorkbook) to generate medium-heavy excel files because the standard FileOutputExcel from Talend always crash by memory issues.
With tFileExcelWoorkbook I have two problems:
1. I have a template which I copy every time I want to generate the report. This template has a little header with a summary of the content (count of rows and total of a numeric colum). Under this data there are the column headers.
| TOTAL ROWS | TOTAL $ |
| 549.660 | 400,000,00 |
|
| COLUMN 1 | COLUMN 2 | COLUMN 3 |
| ###### | ###### | ###### |
| ###### | ###### | ###### |
| ###### | ###### | ###### |
I want to fill the two top cells (Total Rows and Total $). However, when i try to do it I configure tFileExcelSeetOutput with
Row start index (starts with 1) = 2 (to fill the second row's cells). But appears this error:
Exception in component tFileExcelSheetOutput_2
java.lang.IllegalArgumentException: Attempting to write a row in the range that is already written to disk.
On the template these cells are empty and there is not any value, what can I do with it?
2. I want to generate an excel with 75.000 rows aprox (xlsx - 2007) and 27 columns (two of them have a lot of text). The job begins ok but suddenly an error stop the process: JAVA HEAP MEMORY. I've modify the configuration file
Talend-Studio-win32-x86.ini to change the params Xms and Xmx but if I modify it with any value, Talend doesn't launch and appears a JVM error. What can we do? I'm using a 32bits machine and this configuration:
-vmargs
-Xms64m
-Xmx1000m
-XX:MaxPermSize=512m
-Dfile.encoding=UTF-8
Cheers and thanks.
