This will not work. As well as getting a warning for the use of the command attribute, the whole line needs to be interpreted by a shell. Instead, you will probably see a usage error from the first program on the line:

class="org.jboss.resource.adapter.jdbc.local.LocalTxDataSource"> <property name="jndiName">java:/HelloWorldDS</property> <!-- HSQLDB --> <property name="driverClass"> org.hsqldb.jdbcDriver </property> <property name="connectionURL"> jdbc:hsqldb:hsql://localhost </property> <property name="userName">sa</property> <property <property <property <property name="minSize">0</property> name="maxSize">10</property> name="blockingTimeout">1000</property> name="idleTimeout">100000</property>

[exec] The command attribute is deprecated. Please use the executable attribute and nested arg elements. [exec] ps: error: Garbage option. [exec] usage: ps -[Unix98 options] [exec] ps [BSD-style options] [exec] ps --[GNU-style long options] [exec] ps --help for a command summary [exec] Result: 1

Again, the XML header and schema declaration aren t important for this example. You set up two beans: The first is a factory that can produce the second type of bean. The LocalTxDataSource is effectively now your database connection pool, and all your connection pool settings are available on this factory. The factory binds a managed datasource under the JNDI name java:/HelloWorldDS. The second bean configuration declares how the registered object named HelloWorldDS should be instantiated, if another service looks it up in the JNDI registry. Your Hello World application asks for the datasource under this name, and the server calls getDatasource() on the LocalTxDataSource factory to obtain it.

You could set vmlauncher="false" to ensure that the program is executed through the Ant support scripts, rather than any launcher code built directly into the Java libraries. This may work. However, the method that really works is to start the shell as the command, and pass in a string containing the parameters. The Unix sh program does let you do this with its -c command but it wants the commands it has to interpret to follow in a quoted string. XML does not permit double quotes inside a double quote delimited literal, so you must use single quotes, or delimit the whole string in the XML file with single quotes:

Also note that we added some line breaks in the property values to make this more readable you shouldn t do this in your real configuration file (unless your database username contains a line break). Configuring the persistence unit Next, you need to change the persistence unit configuration of the Hello World application to access a managed JTA datasource, instead of a resource-local connection pool. Change your WORKDIR/etc/META-INF/persistence.xml file as follows:

<exec executable="sh" failonerror="true"/> <arg line="-c 'ps -ef | grep java > processes.txt'" /> </exec>

<persistence ...> <persistence-unit name="helloworld"> <jta-data-source>java:/HelloWorldDS</jta-data-source> <properties> <property name="hibernate.show_sql" value="true"/> <property name="hibernate.format_sql" value="true"/> <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/> <property name="hibernate.hbm2ddl.auto" value="create"/> </properties> </persistence-unit> </persistence>

You removed many Hibernate configuration options that are no longer relevant, such as the connection pool and database connection settings. Instead, you set a <jta-data-source> property with the name of the datasource as bound in JNDI. Don t forget that you still need to configure the correct SQL dialect and any other Hibernate options that aren t present in default.persistence.properties. The installation and configuration of the environment is now complete, (we ll show you the purpose of the jndi.properties files in a moment) and you can rewrite the application code with EJBs. Writing EJBs There are many ways to design and create an application with managed components. The Hello World application isn t sophisticated enough to show elaborate examples, so we ll introduce only the most basic type of EJB, a stateless session bean. (You ve already seen entity classes annotated plain Java classes that can have persistent instances. Note that the term entity bean only refers to the old EJB 2.1 entity beans; EJB 3.0 and Java Persistence standardize a lightweight programming model for plain entity classes.)

A command that uses both single and double quotes needs to use the " notation instead of the double quote. The simple example shown does not have this problem. The Windows NT command shell CMD behaves moderately the same as the Unix one, except there is no ps command installed by default, so a more contrived example will be used:

Every EJB session bean needs a business interface. This isn t a special interface that needs to implement predefined methods or extend existing ones; it s plain Java. Create the following interface in the WORKDIR/src/hello package:
