I am trying to pass an array of Strings to insert into an oracle table in 1 hit.
I have defined types in oracle:

and have written the code:

However I get an error when i try and run it:
Exception in thread "main" java.sql.SQLException: Fail to convert to internal representation: v4
at oracle.jdbc.driver.DatabaseError.throwSqlException(
at oracle.jdbc.driver.DatabaseError.throwSqlException(
at oracle.jdbc.oracore.OracleTypeADT.toDatum(
at oracle.jdbc.oracore.OracleTypeADT.toDatumArray(
at oracle.jdbc.oracore.OracleTypeUPT.toDatumArray(
at oracle.sql.ArrayDescriptor.toOracleArray(
at oracle.sql.ARRAY.<init>(
at TestArray.main(

Anyone got any ideas how to do an insert with an array in oracle?

I don't have much experience with Oracle, so this could be wrong, but shouldn't col1 be of type array_of_persons..?

Thanks folks.
Lorand you were right the columns didnt match.
Anil your example was a great link, I have decided to go the package route for my solution.
