FIX: Java OLE DB Simple Provider Does Not Work Reliably

ID: Q225047

The information in this article applies to:

Microsoft Visual J++, version 6.0
OLE DB Simple Provider Toolkit, version 2.0
Microsoft Data Access SDK, versions 2.0, 2.01, 2.1
Microsoft Data Access Components version 2.1 (GA)

SYMPTOMS

An OLE DB Provider created using the Visual J++ 6.0 and the OLE DB Simple Provider Toolkit does not work reliably. When attempting to use such a provider from ActiveX Data Object (ADO) via the Recordset.Open() method, the following error occurs:

-2147217865 (0x80040E37) Description unavailable.

The following application error may occur when using the provider from a Visual J++ or Visual Basic client:

The instruction at '0x7c00ba36' referenced memory at '0x00000004'. The memory could not be 'read'.

The following application error may occur when using the provider from a Visual C++ client:

Unhandled exception in <program.exe> (MSJAVA.DLL): 0xC000005: Access Violation

CAUSE

The Microsoft OLE DB Simple Provider component (Msdaosp.dll) does not properly implement COM reference counting. This causes erratic results with any client of the provider, because the provider may release itself when its real reference count is greater than zero.

RESOLUTION

This problem has been fixed with Microsoft Data Access Components (MDAC) 2.1 Service Pack 2 (SP2). You can download MDAC 2.1 SP2 from the following Microsoft Universal Data Access Web site:

http://www.microsoft.com/data/download.htm

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

The new release of MDAC also fixes a problem in the Java OLE DB Simple Provider, which causes access violation errors when using the Recordset.Delete() method.
