jtds blob size

When I try to insert more then 200Mb data into blob field (varbinary) using jtds jdbc-driver I've got an error. Connection is going closed. In fact I cant insert so much data with other tools too (TOAD for MSSQL).Could you try Microsoft JDBC driver for SQLServer 2005? This may work better. In fact we are planning a v 1.1 release this August. This release can handle larger datatypes better.
