BLOB Error with JDBC driver 8.1.5

Question

Hello.
I tried to run the sample code that I got from OTN, but
I couldn't run it because of some errors.
Would you please help me?
*** The sample code that I tried to run ***
I got it from "SQLJ & JDBC Advanced Samples" in OTN.
Sampl code Name: LOBSample
*** Erroe Message ***
Error in retrieving and drawing map for selected airport
java.sql.SQLException: ORA-06550: line 1, column 22:
PLS-00302: component 'GETCHUNKSIZE' must be declared
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
This error occurred when p_blob.getBinaryStream() was called.
(p_blob was an BLOB object)
*** Environment ***
OS: Windows NT 4.0 SP3
RDBMS: Oracle 8 R8.0.5
JDBC: Oracle JDBC Thin Driver v8.1.5

Hi,
The method getBytes() does not work, and produce the following
error, when the size is big.
java.sql.SQLException: ORA-21560: argument 2 is null, invalid, or
out of range
ORA-06512: at "SYS.DBMS_LOB", line 458
ORA-06512: at line 1
Since getchunksize() will also produces the same error as
getBinaryStream() ('GETCHUNKSIZE' must be declared) therefore, I
have no idea how to find the best value to chop the data to
retrieve it, except try and error. The example I am working on
32000 bytes seems to be the ideal size, and it causes error when
the size get bigger. I am currently working on a NT server. I
guess the ideal size can differ from server to server. Does
anyone has better suggestion to get the ideal size?
