I use php with h2 database at resin server that support php.
I have a paging page that has a list af articles and I use a connection pooling for the database.
The page seems to display ok at IE but at the log of resin the error "the object is already closed at org.h2.jdbc.jdbcStatement.CheckClosed.java:812 etc." is displayed.
Maybe the driver try to release this Statement object's database and JDBC resources and find that some object is already close.
As I understant this error is here for a pdo prepared statement.
My code that I see the error is like this
$query="select count(*) as a from c where b=?";
I'm confused, are you using Java or PHP, as the error (org.h2.jdbc.jdbcStatement.CheckClosed.java:812) indicates you're using Java somewhere.
Also, what database system are you using? I'm not aware of a database called "h2".
