Iam trying to connect hiberante with oracle 10g
Iam using Oracle 10g express edition.

<hibernate-configuration>

<session-factory>

<!-- Database connection settings -->
<property name="connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="connection.url">jdbcracle:thin:@localhost:1525:xe</property>
<property name="connection.username">user</property>
<property name="connection.password">password</property>

<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>

<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.OracleDialect</property>

<!-- Disable the second-level cache -->
<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>

<!-- Drop and re-create the database schema on startup -->
<property name="hbm2ddl.auto">create</property>

<mapping class="org.hibernate.example.dto.EmployeeDetails"/>

</session-factory>

</hibernate-configuration>


I can able to connect to database separately.while connecting using hiberate,iam getting " java.sql.SQLException: Io exception: The Network Adapter could not establish the connection" error.Please help.

did you correctly check your JDBC URL?
the proper use in my case is: jdbc:oracle:thin:@localhost:1521:test

[code][/code]

<property name="connection.url">jdbc:oracle:thin:@localhost:1525:xe</property>

This is the URL i used.I am getting the error.
