Insert multiple values into one field

Hello,
I am trying to insert a list/menu box with multiple user selected values into a single oracle field. I am using Dreamweaver to generate the jsp pages for me. One of the field options is multiple. When I select this option I am able to select more than one value by holding down the control key, but only one value is being inserted into the database field. How do I insert more than one value?

thanks

<tr valign="baseline">
<td nowrap align="right">DEPLOYSELECTFILES:</td>
<td><select name="DEPLOYSELECTFILES" size="10" multiple>
<option value="test1">test1</option>
<option value="test2">test2</option>
<option value="test2">test3</option>
<option value="test2">test4</option>
<option value="test2">test5</option>
</select>
</td>
</tr>
