Export to Excel not Working

[chetan raj]

Hi all,
I am using displaytags in my reports.
when I click csv export link it is working fine but when
i click excel export link it is giving
the following error

servlet failed with exception java.lang.NULLPOINTER Exception
at org.displaytag.export.ExportViewFactory.getView(ExportViewFactory.java:161)

1)Can anybody tell where i am going wrong. How can i make my Excel Export work.

I have displaytag1.1 .jar,displaytag-export-poi1.1.jar in
my classpath.

2)If anybody can give clear steps to be followed
while using displaytags will be helpful.
3) If I want only Excel export link on report but not CSV export link.
where and what changes i have to do for this to effect.

thanks in advance
