问题
I am trying to connect XPagesJDBC.nsf to a simple MS Access database, it connects Successfully and i am able to perform the @JdbcInsert , Update, Delete. also able to execute SQL Query operations.
But i am facing an issue while trying to showing data in ViewPanel control with JDBC Query datasource type.
It give bellow error
Error while reading the relational data
Invalid Fetch Size
and a long StackTrace, i am copying some part of stack trace bellow;
I think this error is specific to MS Access, because i could find some successful implementation with other RDBMS also it work fine with "durby" at my end.

回答1:
The tongue-in-cheek-answer: get a database :-) The problem seems to be well known and plagues others too to quite some extend. The batch-size parameter (first link) might work. You also could revisit your requirements. Would DECS do the trick?
