The JVM includes support
for Java stored procedures, methods, triggers, Enterprise JavaBeans?„? (EJBs),
CORBA, IIOP, and HTTP.
The inclusion of Java within the Oracle database allows Java developers to leverage
their skills as Oracle applications developers. Java applications can be deployed in
the client, Application Server, or database, depending on what is most appropriate.
Oracle Database 11g includes a just-in-time Java compiler that is enabled by default.
We briefly discuss some aspects of Java development in Chapter 14.
Oracle and web services
As of Oracle Database 11g, the database can serve as a web services provider implemented
through XML DB in the database. Web services enable SQL or XQuery to
submit queries and receive results as XML, or invoke PL/SQL functions or package
functions and to receive results. XQuery in Oracle Database 11g provides support for
the emerging JSR-225 standard and includes a number of performance enhancements.
Large objects
Interest in the use of large objects (LOBs) is growing, particularly for the storage of
nontraditional datatypes such as images.
