使用closeOnCompletion（）时发生异常

Question

Namaskaram,

I am using H2 database for my Java based Desktop POS (Point of Sale) application. I am getting the below exception, when I try to use the method closeOnCompletion() for my Statement and PreparedStatement objects.

Exception in thread "AWT-EventQueue-0" java.lang.AbstractMethodError: org.h2.jdbc.JdbcStatement.closeOnCompletion()V

Please help.

Answer 1

The default H2 jar file is currently not compiled for Java 7. Java 7 compatibility is disabled in the source code currently.

You can enable it yourself by compiling H2 yourself (using ./build.sh jar ).

Please note the current implementation of closeOnCompletion is a no-op.
