Thanks Li Ying,
I got some information from
http://today.java.net/pub/a/today/2006/01/19/webwork-validation.html?page=3#custom-validators
but I do not want to reinvent the wheel (basically avoid coding my
validation logic in java code). If I
could have my <actionClass>-validation.xml structured as
<validators>
*<country name="USA">
* <!-- Field Validators for email field -->
<field name="email">
<field-validator type="required" short-circuit="true">
<message>You must enter a value for email.</message>
</field-validator>
<field-validator type="email" short-circuit="true">
<message>Not a valid e-mail.</message>
</field-validator>
</field>
<!-- Plain Validator 1 -->
<validator type="expression">
<param name="expression">email.equals(email2)</param>
<message>Email not the same as email2</message>
</validator>
*</country>*
*<country name="AUSTRIA">
* <!-- Field Validators for email2 field -->
<field name="email2">
<field-validator type="email">
<message>Not a valid e-mail2.</message>
</field-validator>
</field>
<!-- Plain Validator 2 -->
<validator type="expression" short-circuit="true">
<param name="expression">email.startsWith('mark')</param>
<message>Email does not start with mark</message>
</validator>
*</country>*
</validators>
I am looking for something like a wrapper on existing bundled validators.
Is it possible.
Regards,
JK.
