Should one use PL/SQL or Java to code procedures and triggers?

Both PL/SQL and Java can be used to create Oracle stored procedures and triggers. This often leads to questions like "Which of the two is the best?" and "Will Oracle ever desupport PL/SQL in favour of Java?". Many Oracle applications are based on PL/SQL and it would be difficult of Oracle to ever desupport PL/SQL. In fact, all indications are that PL/SQL still has a bright future ahead of it. Many enhancements are still being made to PL/SQL. For example, Oracle 9i supports native compilation of Pl/SQL code to binaries. Not to mention the numerous PL/SQL enhancements made in Oracle 10g and 11g.
