Answer 1

Look here: http://download.oracle.com/docs/cd/B19306_01/java.102/b14355/oraarr.htm#i1058512

and here is my short example:

1) on database

SQL> create or replace type string_array as table of varchar2(100);
  2  /

Type created.

SQL> create or replace function to_string(p_array in string_array) return varchar2
  2  as
  3     l_string varchar2(32767);
  4     i binary_integer;
  5  begin
  6     i := p_array.first();
  7     while i is not null loop
  8        l_string := l_string || p_array(i) || ';';
  9        i := p_array.next(i);
 10     end loop;
 11     l_string := rtrim(l_string, ';');
 12     return l_string;
 13  end;
 14  /

Function created.

2) in java

public class ArrayTest {
    public static void main(String[] args) throws SQLException {
        DriverManager.registerDriver(new OracleDriver());
        OracleConnection connection = (OracleConnection) DriverManager.getConnection(...);

        String[] elements = {"abc", "def", "geh"};
        ArrayDescriptor descriptor = ArrayDescriptor.createDescriptor("STRING_ARRAY", connection);
        ARRAY array = new ARRAY(descriptor, connection, elements);

        OracleCallableStatement stmt = (OracleCallableStatement) connection.prepareCall("{? = call to_string(?)}");
        stmt.registerOutParameter(1, Types.VARCHAR);
        stmt.setARRAY(2, array);
        stmt.execute();

        String result = stmt.getString(1);
        System.out.println("to_string returned: " + result);
    }
}

seems to work: output says

to_string returned: abc;def;geh
