To create the JAR file, we are going to use an Ant task called, appropriately, <jar>. We have dedicated a whole chapter, chapter 6, to this and the other tasks used in the packaging process. For this introductory tour of Ant we use the task at its simplest, when it can be configured to make a named JAR file out of a directory tree:

The SQL error is caught by Hibernate and converted into an optimistic locking exception you can then handle in application code. Other options for the check attribute are as follows:

If you enable check="count", Hibernate checks the number of modified rows using the plain JDBC API. This is the default and used when you write dynamic SQL without stored procedures. If you enable check="param", Hibernate reserves an OUT parameter to get the return value of the stored procedure call. You need to add an additional question mark to your call and, in your stored procedure, return the row count of your DML operation on this (first) OUT parameter. Hibernate then validates the number of modified rows for you.

This shows the advantage of placing intermediate code into the build directory: you can build a JAR file from it without having to list what files are included, because all files in the directory tree should go in, which, conveniently, is the default behavior of the <jar> task. With the destination directories defined, we now have completed the directory structure of the project, which looks like the illustration in figure 2.2. When the build is executed, a hierarchy of folders will be created in the class directory to match the source tree, but as these are automatically created we are not worrying about them.

Mappings for insertion and deletion are similar; all of these must declare how optimistic lock checking is performed. You can copy a template from the Hibernate startup log to get the correct order and number of parameters. Finally, you can also map stored functions in Hibernate. They have slightly different semantics and use cases. Mapping stored functions A stored function only has input parameters no output parameters. However, it can return a value. For example, a stored function can return the rank of a user:

Figure 2.2 The directory layout for our project: a source tree separate from the build and distribution output. The shaded directories and files created by Ant during the build.

<database-object> <create> create or replace function GET_USER_RANK (IN_USER_ID int) return int is RANK int; begin select RANKING into RANK from USERS where USER_ID = IN_USER_ID; return RANK; end; </create> <drop> drop function GET_USER_RANK </drop> </database-object>

Creating the build file Now that we have the files in the right places, and we know what we want to do, the build file needs to be rewritten. Rather than glue all the tasks together in one long list of actions, we have broken the separate stages directory creation, compilation, packaging, and cleanup into four separate targets inside the build file.

This function returns a scalar number. The primary use case for stored functions that return scalars is embedding a call in regular SQL or HQL queries. For example, you can retrieve all users who have a higher rank than a given user:

String q = "from User u where u.ranking > get_user_rank(:userId)"; List result = session.createQuery(q) .setParameter("userId", 123) .list();

< xml version="1.0" > <project name="structured" default="archive" > <target name="init"> <mkdir dir="build/classes" /> <mkdir dir="dist" /> </target>

This query is in HQL; thanks to the pass-through functionality for function calls in the WHERE clause (not in any other clause though), you can call any stored function in your database directly. The return type of the function should match the

<target name="compile" depends="init" > <javac srcdir="src" destdir="build/classes" Compiles into the /> output directories </target> <target name="archive" depends="compile" > <jar destfile="dist/project.jar" basedir="build/classes" /> </target> <target name="clean" depends="init"> <delete dir="build" /> <delete dir="dist" /> </target> </project>
