Exception in Using CachedRowSet while populating the Resultset

[amarshi mohanty]

Hi All,

stmt = conn.prepareStatement(sqlStr.toString());
rs = stmt.executeQuery();
crs.populate(rs);

Due To last line i am getting an exception as:
java.sql.SQLException: Invalid column display size. Cannot be less than zero


but if i just execute teh resultset and iterate it ,all works fine.
m using PostGreSQL 8.1.
is there some pblm with postgresql when accessing from CachedRowSet.

Thanks
