ClassCastException error during setting ArrayDesc

Question

We are using the following code to call pl/sql API passing Arrays as parameters. Following code is working fine in Weblogic 8.1 but throwing a ClassCastException in Weblogic 10.3. Could somebody help to resolve the following issue.
public Object doBaseInConnection(Connection connection) throws SQLException
                    OracleCallableStatement callableStatement = (OracleCallableStatement)connection.prepareCall(DBUtils.createPreparedStatementFunctionString("bbvoice_customer_discovery_ng", "validate_3", 8));//BBT Comapanion refresh
     callableStatement.registerOutParameter(1, Types.INTEGER);
     callableStatement.setString(2, identifier);
     callableStatement.setString(3, password);
     if (productSearchList != null)
          ArrayDescriptor arrayDesc = ArrayDescriptor.createDescriptor(configurationService.getConfigurationItem("database.schema.name") + ".PRODUCT_NAME_ARRAY", connection);          ARRAY ocbsArray = new ARRAY(arrayDesc, connection, productSearchList);
          callableStatement.setARRAY(4, ocbsArray);
     else
          callableStatement.setNull(4, Types.ARRAY);
Error Message:
java.lang.ClassCastException: $Proxy428 cannot be cast to oracle.jdbc.OracleConnection
at oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java:155)

Answer 1

Windows requires the Windows ECHO service to be installed when using Coherence via the default Windows Firewall, which is probably not the case by default in corporate environments.
To do so, go to Control Panel, Turn Windows features on or off, Install “Simple TCPIP services”. (Make sure the service is started by default).
This should solve the problem.
