Sun is purchasing the intellectual property of CDC spec phone maker SavaJe. It may be very interesting phone war, we have a couple new big players such as apple and now sun. I think this year may be very interesting for mobile devices. Another point in this war is that Apple don’t support java on his Mac OS X. That means that we all have java 5 update 11 but Mac OS X has java 5 update 7. Now I must review My dreams about MacBook.

News in JDBC 4.0

A new JSR-221 specifies JDBC version 4. A list of changes is not so huge, there’s some minor changes. One of the major changes was addition XML data type support which is mapped to SQLXML java type. Another added data type is RowId interface, SQL ROWID is the fastest way to access data. Another nice enchantment is that you don’t have to call Class.forName and register driver to driver manager. Everything you must do is put JDBC driver into classpath.

There are many minor changes such as adding DatabaseMetaData, adding more methods such as createClob in Connection, free in Array and others, pleas refers to JDBC specification for details, but in my opinion the most change is introduction more implementation of ResultSet and better Exception Handling.

about me

My name is Sebastian Pietrowski. I've finished Warsaw University as Master degree. I started my journey with Java 1.1 with Thread and JDBC programing in 1998 as I worked for merlin.pl. In 1999 I've passed Java Programer Certificate for Java 1.2, and was solution architect of merlin.pl infrastructure when we was moving from pl/sql to J2EE. It was great performance optimization with 10 times more req/sec than in requirements and 85 times faster as original solution.

Currently I work as Expert Software Development Java at F.Hoffmann-La Roche. The company was founded in 1896 and today, Roche employs over 80.000 people. After work I'm involved in activities related to Scala/Lift, Ruby/Rails/Merb, Python/Django. This is because I try to be pragmatic also I'm focused on application performance and tuning with success in my daily work.
