"Problems in database writing"

Hi,
I am trying to write my result in Access database.But I couldn't able to write even though  ODBC Bridge is available in my RM.I am getting the following error
"No suitable driver found for C:\Documents and Settings\ADMIN\Desktop The JDBC driver has thrown an SQLException. This may because of a lack of privileges, wrong table name or url and similar problems. Please note that some databases are case sensitive. Details are given in the message."


Here I am attaching my process.
<operator name="Root" class="Process" expanded="yes">
    <operator name="TextInput" class="TextInput" expanded="yes">
        <list key="texts">
          <parameter key="bmerge" value="C:\Documents and Settings\ADMIN\Desktop\mm"/>
