Cannot pass array to stored procedure in oracle

Question

I am getting following error when I pass array to stored procedure.

java.lang.ClassCastException: weblogic.jdbc.wrapper.PoolConnection_oracle_jdbc_driver_T4CConnection cannot be cast to oracle.jdbc.driver.OracleConnection

I am using Spring MVC with oracle 10g on Weblogic 11g server. I do a JNDI look up to connect to database. I also unchecked the Wrap data types check box in my Data sources configuration on weblogic server and restarted server. But still same error.

I am using ojdbc6-11.2.0.3.jar

Following is the like of code where I get the error

ArrayDescriptor arrayDescriptor =  
    ArrayDescriptor.createDescriptor("Frc.Typ_Frc_Varray", 
        (oracle.jdbc.driver.OracleConnection)  dataSource.getConnection());  

I have data source autowired as follows

       @Autowired  
       DataSource dataSource; 

Answer 1

尝试像这样进行转换：

(oracle.jdbc.driver.OracleConnection)  ((WLConnection)dataSource.getConnection()).getVendorConnection()
