Answer 1

I wrote parameterType & Map example. It works on my test data.

XML:

<update id="isPublicObject" parameterType="map" statementType="CALLABLE">
    declare
        v_bool BOOLEAN := TRUE;
    begin
        v_bool := PACKNAME.STF$IS_PUBLIC_OBJECT(#{id});
        #{result,jdbcType=VARCHAR,mode=OUT} := CASE WHEN v_bool THEN 'TRUE' ELSE 'FALSE' END;
    end;
</update>

Mapper:

public interface PLSQLMapper {
    public void isPublicObject(Map<String, Object> parameterMap);
}

Main:

PLSQLMapper mapper = session.getMapper(PLSQLMapper.class);

Map<String, Object> parameterMap = new HashMap<String, Object>();
parameterMap.put("id", 1);
mapper.isPublicObject(parameterMap);
System.out.println("result: " + parameterMap.get("result"));

The #{} syntax can only be used for parameter substitution. It is not a variable that gets set after the execution of the PL/SQL. It can only be set before the prepared statement is built.

One way of going forward would be to use stored procedure and use an OUT param to get your result out.
