Hi, I noticed u use the jdbc-odbc bridge, which does have multi-theading problems, (the odbc part). Try synchronising the part through which data is updated on the database, so that only one thread uses it at a time.

Hi - Just use the synchronized modifier on any classes that access the JDBC connection. Over to you
