How to find a JNDI resource inside a hibernatetool Ant task

Question

I want to generate my database schema using Ant. I am using the hbm2ddl task.

I am using Hibernate with JNDI. My hibernate.cfg.xml looks like this:

<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Database connection settings --> <property name="connection.datasource">java:comp/env/jdbc/my_app</property> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <property name="current_session_context_class">thread</property> <!-- Mapping --> </session-factory> </hibernate-configuration> 

My $ CATALINA_HOME / webapps / myapp / META-INF / context.xml looks like this:

 <Context> <Resource name="jdbc/my_app" global="jdbc/my_app" auth="Container" type="javax.sql.DataSource" username="userA" password="userA123" driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/myapp?autoReconnect=true" maxActive="8" maxIdle="4"/> </Context> 

And inside $ CATALINA_HOME / webapps / myapp / WEB-INF / web.xml I have:

  <resource-ref> <description>DB Connection</description> <res-ref-name>jdbc/my_app</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> 

Inside build.xml I have the following goal.

 <target name="schema" description="Generate DB schema from the O/R mapping files"> <hibernatetool destdir="${basedir}"> <classpath path="${java.src.home}"> <fileset dir="${java.src.home}"> <include name="**/*.hbm.xml"/> </fileset> </classpath> <configuration configurationfile="${java.src.home}/hibernate.cfg.xml"/> <hbm2ddl drop="true" create="true" export="true" outputfilename="myapp-ddl.sql" delimiter=";" format="true"/> </hibernatetool> </target> 

The problem is that ant cannot find the Resource element stored in context.xml.

 [hibernatetool] Error #1: org.hibernate.HibernateException: Could not find datasource 

I tried without success to add a nex fragment inside the classpath element.

  <fileset dir="${web.home}/META-INF"> <include name="context.xml"/> </fileset> 

How can I tell ant to search for a Resource defined in context.xml?

I am posting a complete stacktrace error.
