Poi's Upload problem: RecordFormatException

[Baseet Ahmed]

Salaam/Hi,

All:
Please help us out in the below problem while uploading excel file through POI's api.

The java program throws following exception while reaching at this line POIFSFileSystem fs = new POIFSFileSystem(item.getInputStream());
//item is FileItem object

Exception message:
org.apache.poi.hssf.record.RecordFormatException: Unable to construct record instance, the following exception occured: null

& In tomcat's catalina window:
java.lang.reflect.InvocationTargetException
at sun.reflect.GeneratedConstructorAccessor28.newInstance(Unknown Source)
at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27)
at java.lang.reflect.Constructor.newInstance(Constructor.java:274)
at org.apache.poi.hssf.record.RecordFactory.createRecord(RecordFactory.java:224)

at org.apache.poi.hssf.usermodel.HSSFWorkbook.<init>(HSSFWorkbook.java:163)
at org.apache.poi.hssf.usermodel.HSSFWorkbook.<init>HSSFWorkbook.java:1

NB:The excel file is having four sheets with tabular formatted data.


Thank you.

Regards
Baseet Ahmed

Is the uploaded file byte by byte identical to the source file? That is to say, are you sure it didn't get corrupted? Try to open it with Excel to see if that works.

Yes Ulf,
Am able to open it in MS Excel without any problem.
But causing the problem while doing upload using POI.

Please suggest any other action to be taken.

Just to make sure: can you open the file you uploaded after the upload - the copy that's now on the server? Have you made sure that it is byte for byte identical to the original file? Can you open the original file with POI?

We have checked the uploaded file(on temp area of tomcat) with our original file. Both are looking same.Probably this is causing problem with particular excel file. Because other excel files are working fine.
