Zdravim konferenci,
jiz temer den se trapim s rozchozenim iReport na Hibernate. Pokud
vytvorim novy datasource (typu Hibernate Connection) a zkusim
otestovat pripojeni (tlacitkem test - nahraje se konfigurace
hibernate.cfg.xml, ktera se hleda v classpath), vse probehne ok.
hibernate.cfg.xml:
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd";>
<hibernate-configuration>
<session-factory>
<property name="connection.driver_class">org.postgresql.Driver</property>
<property
name="connection.url">jdbc:postgresql://localhost:5432/MojeDB</property>
<property name="connection.username">postgres</property>
<property name="connection.password">mojeheslo</property>
<property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property
name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>
<property name="show_sql">true</property>
<property name="current_session_context_class">thread</property>
<property name="hbm2ddl.auto">update</property>
<property name="generate_statistics">true</property>
</session-factory>
</hibernate-configuration>
Kompilace reportu probehne v poradku, spusteni (null datasource)
probehne v poradku, ale pri pokusu o provedeni (vyplneni) formulare
dostanu chybovy vystup:

Print not filled. Try to use an EmptyDataSource...!
Pritom mam v iReport nastaveno classpath k PosgreSQL driveru (bez toho
hlasi, ze nemuze PostgreSQL driver najit) a se stejnym nastavenim
hibernate mi bezi business logika aplikace ve springu.
Budu moc vdecny za kazdy napad, ktery by mi pomohl hnout se z mista.
S pozdravem, Petr Gola
