Bonjour,
J’utilise hibernate spatial (la version trunk des sources) avec Oracle Database 11g Release 2, Hibernate 3.6, Spring 3.04

Dans les traces hibernate je vois que la connection Oracle se coupe brutalement durant l’itération sur le ResultSet.
Parfois cette coupure correspond au fetch size JDBC.
La première requête de la journée fonctionne bien.
Je fais mes test avec Junit.

Cette erreur survient lors de requête hql et seulement si un critère spatial est ajouté.

J'ai cette erreur :
0 ERROR org.hibernate.util.JDBCExceptionReporter:234 - No more data to read from socket

Ou celle ci :
"234 - ORA-22060: argument [2] is an invalid or uninitialized number
ORA-06512: at "MDSYS.SDO_3GL", line 4
ORA-06512: at "MDSYS.SDO_3GL", line 28
ORA-06512: at "MDSYS.MD2", line 642
ORA-06512: at "MDSYS.SDO_GEOM", line 936
ORA-06512: at "MDSYS.SDO_GEOM", line 977
ORA-06512: at "MDSYS.ST_GEOMETRY", line 89
ORA-06512: at "MDSYS.OGC_WITHIN", line 6"

hibernate settings (via spring ) :
---------------------------------------

<property name="hibernateProperties">
<value>
connection.provider_class=org.hibernatespatial.oracle.DefaultConnectionFinder
<!-- SPATIAL SQL oracle dialect -->
hibernate.dialect=org.hibernatespatial.oracle.OracleSpatial10gDialect
hibernate.current_session_context_class=thread
hibernate.transaction.factory_class= org.hibernate.transaction.JDBCTransactionFactory
hibernate.test.validateDataCleanup=false
<!-- hibernate.connection.release_mode=on_close-->
<!-- hibernate.jdbc.use_scrollable_resultset=true-->
</value>


org.hibernatespatial.oracle.OracleSpatial10gDialect.properties File :
---------------------------------------
OGC_STRICT=true
CONNECTION-FINDER=org.hibernatespatial.oracle.DefaultConnectionFinder


hibernate-spatial.cfg.xml
---------------------------------------
<?xml version="1.0" encoding="UTF-8"?>
<hibernate-spatial>
<default_dialect>org.hibernatespatial.oracle.OracleSpatial10gDialect</default_dialect>
<dialect>org.hibernatespatial.oracle.OracleSpatial10gDialect</dialect>
<precision_model>FIXED</precision_model>
<precision_model_scale>5</precision_model_scale>
</hibernate-spatial>

<bean id="dataSource" class="oracle.jdbc.pool.OracleDataSource" destroy-method="close">
<property name="connectionCachingEnabled" value="true" />
<property name="URL" value="jdbc:oracle:thin:@server:1521:SID"/>
<property name="user" value="USER"/>
<property name="password" value="PASS"/>
<property name="connectionCacheProperties">
<props merge="default">
<prop key="MinLimit">3</prop>
<prop key="MaxLimit">20</prop>
</props>
</property>
</bean>



Toute idée est la bienvenue, d'avance merci.


Jean-Marc
