Is it possible to turn off "save as XLS" in Viewer

[Mange]

Hi,

 

I'm very new (started 2 days ago) with JasperReports. Great product!

 

I did one tutorial (very simple) and added the following:

JasperViewer.viewReport(jasperPrint);

 

When tried to save in XLS format I got an error:

java.lang.NoClassDefFoundError: org/apache/poi/hssf/usermodel/HSSFCellStyle

 

I tried to open the jakarta-site so I can get the jar-file, but no luck. I will try later again.

 

I do wonder though, is it possible to remove some "Files of Type", like XLS, in the "Save As" ?

 

TIA
