Hibernate version: 3.02
Mapping documents:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping SYSTEM "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="com.playlogix.traventure.ContentType" table="CONTENTTYPE">
<id name="id" column="uid" type="long">
<generator class="increment"/>
</id>
<property name="description" type="string" unique="true" not-null="true"/>
</class>
</hibernate-mapping>
The error occurs when I execute :
Code:
<%
InitialContext ctx = new InitialContext();
SessionFactory factory = (SessionFactory)ctx.lookup("java:/hibernate/SessionFactory");
Session hsession = factory.openSession();
try {
ContentType contentType = new ContentType();
contentType.setDescription("Article");
hsession.save(contentType);
contentType = new ContentType();
contentType.setDescription("News");
hsession.save(contentType);
contentType = new ContentType();
contentType.setDescription("Advert");
hsession.save(contentType);
}catch (Exception e){
e.printStackTrace();
} finally {
hsession.close();
} %>
inside a jsp file.
If I execute the following outside of JBoss, it works and the rows are inserted :
Code:
ContentType contentType = new ContentType();
contentType.setDescription("Article14");
session.save(contentType);
contentType = new ContentType();
contentType.setDescription("News14");
session.save(contentType);
contentType = new ContentType();
contentType.setDescription("Advert14");
session.save(contentType);
