Re: InstantDB: InstantDB table access from CMP EJB


Peter --

Further follow-up....
If I create and populate the table using ScriptTool, and then try to use
the servlet to do the same (the servlet first attempts to drop the
table), I get the following stack trace:

Cannot get connection: java.sql.SQLException: IO problem:
java.sql.SQLException: Internal error header recLength=3 
Computed record length should be 419
Table: NE$db$Cols
