About this task
Each typed data field must define its required syntactic
validation in the dsetype.xml file.
You can also use the validation
process in the startup sequence by passing data through the request
to the CSEstablishSessionServlet. The startup operation may define
its typed data elements with the same validators.
For an example
of how data field validation works on a data field with the "Amount"
data type, see the following in the HTML Sample Application:
- accountTransferData.amount data field in accountTransferOp.xml
- Amount type in dsetype.xml
- com.ibm.btt.poc.util.AmountValidator class
- <dse:text dataName="amount" error="yes" size="10" maxLength="10"/> in
transfer.jsp
- <dse:error dataName="amount"/> in transfer.jsp
