Transaction management in Spring and EJB3

In this speech we will discuss about transaction management in Java Enterprise Application, with Spring and EJB3.0 technologies. Starting with a brief recap of basic properties of transactions (acid, concurrent accesses problems, isolation levels), we will analyze different models for transaction management and we will discuss how Spring and EJB address these different approaches, trying to figure out pros and cons of both. In the end, we will discuss briefly about XA transactions.

From the Semantic Web to the Web of Data: ten years of linking up

More than ten years have passed since Tim Berners Lee's visionary article on Scientific American envisaging a Web that could be understood by machines. Since then a huge effort has been done both in the scientific community and the W3C to build a solid theoretical foundation as well as a wide set of technology specifications for use in a broad range of fields from knowledge representation and data integration to the semantic search. Over the last two years though a new paradigm emerged, the so called Linked Data approach, which has the potential to turn the internet into the Web of Data envisioned by Berners-Lee. Through a series of failures and success stories this talk provides a pragmatic overview on the possibilities offered by these technogies and their Java reference implementations. In particular, we will show how Microformats, RDF, SPARQL, RDFa and the Linked Data paradigm could be used to solve new and exciting challenges on the Web to come.
