Help with Array

I have a java application that moves data from our erp platform
(progress) into a Postgres database. One of the fields in progress is
a character array. I haven't had any luck getting this field to
transfer. What I would like to do is something like:

....
preparedStatement.setArray(i,resultSet.getArray(i));
....

however this throws java.lang.UnsupportedOperationException
I have tried several other ways, with no luck.

...
preparedStatement.setObject(i,resultSet.getObject(i));
...
throws
java.sql.SQLException: ERROR: column "so_slspsn" is of type character
varying[] but expression is of type character varying

and

...
preparedStatement.setObject(i,resultSet.getObject(i),2003);
...
throws
org.postgresql.util.PSQLException: Unsupported Types value: 2,003

What am i doing wrong?
