Answer 1

You need to put the Oracle driver jar onto your classpath.

If you are using an older JDBC driver then you may wish to download a newer one from here

http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc_111060.html

They're generally backwards compatible.

Also check that your driver class has been loaded and is correct.

Class.forName("oracle.jdbc.driver.OracleDriver");

See for a code example http://w2.syronex.com/jmr/edu/db/oracle-and-java
