This is a follow-up to Executing native query with Hibernate 4.1

I've tried the options in the listed answer but we get errors and are unable to unwrap the proxied connection into the native connection which Oracle needs

Option 2 code

public void execute(Connection connection) throws SQLException {
    OracleConnection oracleConnection = connection.unwrap( OracleConnection.class );
    ...
}

Error

java.lang.reflect.UndeclaredThrowableException
ERROR [stderr] (http-localhost/127.0.0.1:8080-3) at $Proxy64.unwrap(Unknown Source)

Option 3 code

public void execute(Connection connection) throws SQLException {
    Connection unproxiedConnection = ( (JdbcWrapper<Connection>) connection ).getWrappedObject();
    ...
}

Error

java.lang.ClassCastException: org.jboss.jca.adapters.jdbc.jdk6.WrappedConnectionJDK6 cannot be cast to oracle.jdbc.OracleConnection

any suggestions?

I've also tried this option SessionFactory.openSession(Connection) in Hibernate 4 but that class does not get instantiated at all

Update:

Option 2 code works correctly. The problem was we had 2 versions of ojbc.jar - one as a Jboss module and one within the EAR, hence the Exception.

尝试以下

我遇到了同样的问题。我们使用的是 spring，它有一个名为 NativeJdbcExtractor 的类。它有许多实现，以下一个适用于 TomCat。Jboss 有一个特定的实现，称为 JBossNativeJdbcExtractor

<bean id="jdbcExtractor" class="org.springframework.jdbc.support.nativejdbc.CommonsDbcpNativeJdbcExtractor"></bean>

在您的 DAO 中，您可以注入 bean 并使用以下方法

protected NativeJdbcExtractor jdbcExtractor;
Connection conn=jdbcExtractor.getNativeConnection(oracleConnection);

选项 2 代码正常工作。

IE。

OracleConnection oracleConnection = connection.unwrap( OracleConnection.class );

问题是我们有 2 个版本的 ojbc.jar - 一个作为 Jboss 模块，一个在 EAR 中，因此是 ClassCastException。

如评论中所述，此代码也有效

oracle.jdbc.driver.OracleConnection oc = (oracle.jdbc.driver.OracleConnection) connection.getMetaData().getConnection();
