Trying to get hibernate working w/ struts. Followed the instructions here for the plugin:
http://www.hibernate.org/105.html
hibernate.cfg.xml :
Code:
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory name="java:/hibernate/SessionFactory">
<property name="connection.datasource">java:/CummingsDB</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="hbm2ddl.auto">update</property>
<mapping resource="Trailers.hbm.xml"/>
<mapping resource="TrailerSales.hbm.xml"/>
<mapping resource="Customers.hbm.xml"/>
<mapping resource="Makes.hbm.xml"/>
<mapping resource="Provinces.hbm.xml"/>
<mapping resource="Countries.hbm.xml"/>
</session-factory>
</hibernate-configuration>
I'm trying to instantiate like this :
Code:
SessionFactory sf = null;
Session session = null;
Context ctx;
try {
ctx = new InitialContext();
sf = (SessionFactory) ctx.lookup("java:/hibernate/SessionFactory");
session = sf.openSession();
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
I just get null pointer exception:
java.lang.NullPointerException
