Problem passing oracle.sql.ARRAY to Oracle

Question

I am having ClassCastException when I try to pass a oracle.sql.ARRAY to a Oracle Package.
Here is my code:
PreparedStatement stmt = null;
String strArray[] = { "1,2,3,4,5" };
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
//encounter Exception on the line below.
ARRAY array_to_pass = new ARRAY( descriptor, dbConnection, strArray );
String queryStr = "begin TEST_PAC_1.TEST_PROC_2(?); end;";
stmt = dbConnection.prepareStatement(queryStr);
stmt.setArray( 1, array_to_pass );
stmt.execute();
I understand that oracle.sql.ARRAY has been replaced by weblogic.jdbc.vendor.oracle.OracleArray in Weblogic.
MY QUESTION IS: HOW DO I INSERT MY STRING ARRAY INTO THE OracleArray and pass it to the plsql.
Really frustrated searching through the forums for the whole day,
Thanks,

Try this if you are at weblogic 8.1:
Connection con = getConnectionFromDataSource();
Connection vendorConnection = ((WLConnection)con).getVendorConnection();
// use direct oracle connection.
ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor( "TEST_PAC_1.TEST_COLL_2", dbConnection );
vendorConnection.close();
Beware that you should be very careful as you are going to use a direct vendor
connection.
The better aproach is to pass the string array as a delimited string to your storad
procedure and parse it in the SP - then you don't have to mess up with vendor-specific
handling.
Hope this helps.
