For these reasons, we do not encourage its use in normal situations. Certainly using the <arg line> option for specifying arguments is risky. The argument-by-argument specification is more detailed, providing more information about the type of arguments to Ant, and to readers. The final option, path, takes a path parameter, generating a single argument from the comma- or colon-separated file path elements passed in

This query returns the largest bids in the database. Where clause subselects are often combined with quantification. The following query is equivalent:

As with other paths in Ant, relative locations are resolved and Unix or MS-DOS directory and path separators can be used. The invoked program will receive a path as a single argument containing resolved file names with the directory and path separators appropriate to the platform. 5.2.4 Defining system properties System properties are those definitions passed to the Java command line as -Dproperty=value arguments. The nested <sysproperty> element lets you define properties to pass in. At its simplest, it can be used as a more verbose equivalent of the command line declaration, such as when defining the socks server and port used to get through a firewall:

select * from BID b where b.AMOUNT >= all(select c.AMOUNT from BID c)

<sysproperty key="socksProxyHost" value="socks-server"/> <sysproperty key="socksProxyPort" value="1080"/>

An SQL restriction criterion is expressed in a sophisticated expression language that supports mathematical expressions, function calls, string matching, and perhaps even more sophisticated features such as full-text search:

There are two alternate options instead of the value parameter: file and path. Just as with arguments, the file attribute lets you name a file; Ant resolves relative references to pass in an absolute file name, and convert file separators to the native platform. The path attribute is similar, except that you can list multiple files

select * from ITEM i where lower(i.DESCRIPTION) like '%gc%' or lower(i.DESCRIPTION) like '%excellent%'

Many Hibernate books list all possible XML mapping elements and mapping annotations in an appendix. The usefulness of doing so is questionable. First, this information is already available in a convenient form; you only need to know how to get it. Second, any reference we might add here would be outdated in a matter of months, maybe even weeks. The core Hibernate mapping strategies don t change that often, but little details, options, and attributes are always modified in the process of improving Hibernate. And isn t the main reason you want a mapping reference so you have an upto-date list of all options

<sysproperty key="configuration.file" file="./config.properties"/> <sysproperty key="searchpath" path="build/classes:lib/j2ee.jar" />

You can get a list of all XML mapping elements and attributes bundled with Hibernate in hibernate-mapping-3.0.dtd. Open this file in any text editor, and you ll see that it s fully documented and very readable. You can print it out as a quick reference if you work with XML mapping files. If the syntax of the DTD bothers you, do a few quick search/replace operations on a copy of this file to replace the DTD tags with something you prefer in your printed output. You can get a list of all mapping annotations by reading the Javadoc for the javax.persistence and org.hibernate.annotations packages. The Javadoc is bundled with the Hibernate Annotations package. For example, to get a clickable, up-to-date reference for all Hibernate extension annotations, open api/org/hibernate/annotations/package-summary.html.

Running the program in a new JVM As we stated at the beginning of section 5.1, the <java> task runs the program inside the current JVM unless the fork attribute is set to true. This can reduce the startup time of the program. As an experiment, we can run the search in a new JVM:
