Hi All!
I run following statement and get error. My question is how I can check if missing class in database or not?
Thanks.

SQL> SET SERVEROUTPUT ON
SQL> CALL DBMS_JAVA.SET_OUTPUT(6000); Call completed.

SQL> DECLARE
  2 in_addr MDSYS.GEOCODE_RECORD_TYPE := MDSYS.GEOCODE_RECORD_TYPE(null, nu;
  3 out_addr MDSYS.GEOCODE_RECORD_ARRAY_TYPE := MDSYS.GEOCODE_RECORD_ARRAY_;
  4 meta MDSYS.GEOCODE_SERVER_PROPERTY_TYPE := MDSYS.GEOCODE_SERVER_PROPERT;
  5 BEGIN

  6     DBMS_OUTPUT.PUT_LINE('Geocoded address: ');
  7     out_addr := intERactive(meta, in_addr);
  8     DBMS_OUTPUT.PUT_LINE(out_addr(1).city);
  9     DBMS_OUTPUT.PUT_LINE(out_addr(1).country_subdivision);
 10     DBMS_OUTPUT.PUT_LINE(out_addr(1).country);

 12     DBMS_OUTPUT.PUT_LINE(out_addr(1).latitude);
 13     DBMS_OUTPUT.PUT_LINE(out_addr(1).longitude);
