V.Narayanan commented on DERBY-2506:
------------------------------------
My derbyall on this patch finished today morning and I had one failure in the
JDBCDriverTest of the compatibility suite.
> There was 1 error:
> 1)
> testJDBCDriver(org.apache.derbyTesting.functionTests.tests.junitTests.compatibility.JDBCDriverTest)java.lang.ClassCastException:
>
> org.apache.derbyTesting.functionTests.tests.junitTests.compatibility.JDBCDriverTest$MyBlob
> cannot be cast to org.apache.derby.client.am.Blob
The error occurred because in the computProtocolAndLengths method of the
NetStatementRequest class I do
else if (((Blob)b).isLocator()){
+ //we are sending locators.
+ //Here the LID local identifier in the FDODSC
+ //FD:OCA descriptor should be initialized as
+ //to contain a BLOB locator.
+ lidAndLengths[i][0] =
+ DRDAConstants.DRDA_TYPE_LOBLOC;
+ lidAndLengths[i][1] = 4;
}
This fails when you use the setObject method of the PreparedStatement class and
pass as parameter a
user implementation of the java.sql.Blob interface. In the JDBCDriverTest
MyBlob extends from java.sql.Blob
and a setObject is done on the MyBlob object.
To overcome this the same method as currently followed for the Layer B
streaming (i.e)
if( b instanceof Blob && ( (Blob) b).willBeLayerBStreamed() )
check to see if the Blob is of type org.apache.derby.client.am.Blob and then
call the isLocator method
should be done.
It is a very small change. I have done this and have restarted the derbyall and
junit tests.
I shall report with these test results tommorrow.
