Hello!
I'm getting a NegativeArraySizeException during the invocation of a package procedure with a CLOB parameter, which is added to the stored proc calling method as a new SqlLobValue:
We are using Spring 3.2.2 and the database is an Oracle 10g installation (10.2).
Using the DefaultLobHandler like this:
we get:
while using the deprecated OracleLobHandler:
everything works.
I debugged the code and I think I tracked the exception rising in an invocation of setCharacterStream() (but as there are no publicly available sources for the Oracle drivers, I'm not 100% sure of that), and I managed to make it work by passing a guessed length as the second parameter of SqlLobValue() constructor.
Since the lob value is a Json string generated by other data, there's no reasonable way to know the lob size in advance (apart from doing not-so-easy precomputations or double-generating the lob to know its size, both of which I'd consider overkill).
Any suggestion?
I'm getting a NegativeArraySizeException during the invocation of a package procedure with a CLOB parameter, which is added to the stored proc calling method as a new SqlLobValue:
Code:
public String executeNativeStoredProcedure(Reader jsonStoreDocumentMessageReader) throws PaxDataException {
try {

SqlLobValue sqlLobValue = new SqlLobValue(jsonStoreDocumentMessageReader, -1, lobHandler);

sqlLobValue.cleanup();
return result.get("OUT") != null ? result.get("OUT").toString() : null;
} catch (Exception e) {
throw new PaxDataException("ArchiviaFiles - " + SPROC_NAME, e);

DefaultLobHandler lh = new DefaultLobHandler();
lh.setStreamAsLob(false);
return lh;
