Thanks for the input - your suggestion revealed an elegant solution. The
framework seems to automatically call validation methods with names of the
form validateActionName. Here's an example from my application. The entry in
struts.xml looks like this:
<action name="dataEntry*" method="dataEntry{1}"
class="com.x.y.action.Request">
<result name="input">/jsp/Request.jsp</result>
<result>
...
</result>
</action>
The action methods in the Request class are defined like this:
public String dataEntrySave() throws Exception {
// save the data
// ...
return SUCCESS;
}
public String dataEntrySubmit() throws Exception {
// submit the data for further processing
// ...
return SUCCESS;
}
and I also have validation methods, which are automatically called by the
framework before the corresponding action method:
public void validateDataEntrySave() {
// validation done before dataEntrySave() is called
}
public void validateDataEntrySubmit() {
// validation done before dataEntrySubmit() is called
}
