java.io.IOException: read past EOF

[John Gilbert]

I am trying to write an Ejb3Directory. It seems to work for index writing but 
not for searching.
I get the EOF exception. I assume this means that either my OutputStream or 
InputStream is doing
something wrong. It fails because the CSInputStream has a length of zero when 
it reads the .fnm section 
of the .cfs file.

Does anyone have any suggestions? 
Thanks!

Here is more background info:
