java.io.IOException: read past EOF
|
|
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:
- Using version 1.4.3
- Stack trace
