Abstract: Apparatus, methods, and computer program products are disclosed for constructing and transmitting an executable software module on a personal information server to a remote computer. The software module is constructed such that once received by a browser displaying a form, it is executed and user data is automatically inserted into an electronic form. The software module contains field names from a downloaded form and matching data items which are inserted into the form on the remote user computer. A method for constructing a shippable software module on a personal information server suitable for execution on a remote computer for inserting data strings into an electronic form is described. A form mapping containing a set of associations between fields in the electronic form (“non-standard fields”) and pre-named fields (“standard fields”) on the personal information server is retrieved. Each mapping is associated with a registered electronic form.
