Set up environment for configurable form handling data. It is important to note that all DatabaseActions use a common configuration format. This group of actions are unique in that they employ a terciary mapping. There is the Form parameter, the database column, and the type. Each configuration file must use the same format in order to be effective. The name of the root configuration element is irrelevant.
<root> <connection>personnel<connection> <table> <keys> <key param="id" dbcol="id" type="int"/> </keys> <values> <value param="name" dbcol="name" type="string"/> <value param="department" dbcol="department_id" type="int"/> </values> </table> </root>The types recognized by this system are:
Type | Description |
---|---|
ascii | ASCII Input Stream, a CLOB input |
big-decimal | a java.math.BigDecimal value |
binary | Binary Input Stream, a BLOB input |
byte | a Byte |
string | a String |
date | a Date |
double | a Double |
float | a Float |
int | an Integer |
long | a Long |
short | a Short |
time | a Time |
time-stamp | a Timestamp |
now | a Timestamp with the current day/time--the form value is ignored. |
image | a binary image file, we cache the attribute information |
image-width | the width attribute of the cached file attribute. NOTE: param attribute must equal the param for image with a "-width" suffix. |
image-height | the width attribute of the cached file attribute NOTE: param attribute must equal the param for image with a "-height" suffix. |
image-size | the size attribute of the cached file attribute NOTE: param attribute must equal the param for image with a "-size" suffix. |
