Hi Pankaj Tiwari,
you are building against java 6, and unfortunately this is not yet
supported.

Point your JAVA_HOME to a java 1.5 JDK and it will build correctly.
Please note that this does not mean that OpenJPA does not RUN under java
6, simply it will not build against a JDK 1.6.

That is because OpenJPA subclasses some JDBC classes, JDK 6 comes with
new JDBC 4, but at the same time the JPA standard does not yet define
any support for new JDBC 4 types, so current subclasses of OpenJPA are
stuck to JDBC 3. Since JDBC 4 declares new methods and types in
DataSource, PreparedStatement and many other interfaces, it results that
OpenJPA implementations are not complete for JDBC 4 and those errors are
reported.

Bug OPENJPA-5 has a quite extensive discussion on this problem and
possible solutions.

Hope this helps,
Simone
