Unwrap to OracleConnection
提问by mariu
I have this piece of code that used to run properly using JBoss 5.1, Oracle 11, ojdbc6.jar. I was getting the OracleConnection as needed.
我有这段代码，可以使用 JBoss 5.1、Oracle 11、ojdbc6.jar 正常运行。我正在根据需要获取 OracleConnection。
InitialContext ic = new InitialContext();
DataSource ds = ( DataSource ) ic.lookup( "java:/" + dataSource );
Connection con = ds.getConnection();
OracleConnection conn = con.unwrap( OracleConnection.class );
Not anymore using JBoss 7, Oracle 11, ojdbc6.jar. It says like this:
不再使用 JBoss 7、Oracle 11、ojdbc6.jar。它是这样说的：
Connection Not a wrapper class for Oracle Connection
Connection 不是 Oracle Connection 的包装类
If you have any idea, please help.
如果您有任何想法，请帮忙。

I use "oracle.jdbc.pool.OracleConnectionPoolDataSource" as datasouce class in glassfish.
我使用“oracle.jdbc.pool.OracleConnectionPoolDataSource”作为 glassfish 中的数据源类。
Use the class or find jboss class.
使用类或查找 jboss 类。
Edit and Try:
编辑并尝试：
public OracleConnection getOracleConnection(Connection connection) throws SQLException {
OracleConnection oconn = null;
try {
if (connection.isWrapperFor(oracle.jdbc.OracleConnection.class)) {
oconn = (OracleConnection) connection.unwrap(oracle.jdbc.OracleConnection.class)._getPC();
}
} catch (SQLException e) {
throw e;
}
return oconn;
}

Try accessing it as a WrappedConnection, like this
尝试将其作为 WrappedConnection 访问，如下所示
Connection con = ds.getConnection();
WrappedConnection wc = (WrappedConnection) con;
OracleConnection conn = (OracleConnection) wc.getUnderlyingConnection();
