DI: Unable to read Excel source

Question

Hi,
We use BusinessObjects Data Services XI 3.1, version 12.1.1 on UNIX Server.We have created BoExcelAdapter to read Excel source and we were not facing any issues in reading the Excel files so far.
Yesterday when we ran the job to read a new excel file, we received the error message 'Could not find worksheet ... in file ..'.
But the excel file has the specified worksheet.
Could you please guide me as to what has caused such an error and how to resolve this.
Thanks,
RaajMahee

Hi RaajMahee
Cause
On Unix, the excel adapter uses the apache poi browser to read the spreadsheet.
When the adapter tries to open the spreadsheet with the poi api, the poi api chokes and gets an exception of ArrayIndexOutofBound.
POI library does not support a feature found in the workbook
Resolution
This problem had already been addressed in the latest poi patch release, poi-3.2-FINAL-20081019.jar.
1. Download the attached file poi-3.7-20101029 and rename it to poi-FINAL-3.7-20101029.jar
2. Copy the poi-FINAL-3.7-20101029.jar file to your $LINK_DIR/lib directory of your Unix/Linux server.
3. Through the Data Services Management Console, stop the excel adapter.
4. Using the Data Services Management console, modify the Excel Adapter's class path and replace the reference to poi-         2.5.1-final-20040804.jar with its full path with poi-FINAL-3.7-20101029.jar with its full path.
5. Save and restart the adapter.
6. Try again processing the Excel file with formulas.
if you want to download the  poi-3.7-20101029 file just follow the link
