The "set property" rule is still going to expect the property names to
match. One thing you might consider is using a BeanInfo class associated
with your bean so that the standard JDK introspection code will work.
Another approach would be to consider modifying your XML structure to look
like this if you can:
<test>
<mail>[EMAIL PROTECTED]</mail>
</test>
Then, you can use the "call method" rule to process it:
digester.addCallMethod("test/mail", "setEmail", 0);
If you can't do this, you will need to write a custom Rule.
