Returning false from the handle Event method will cause the JAXB operation to stop, returning true will allow it to continue (if possible).package validation; import LOCATOR LINE NUMBER: 3 COLUMN NUMBER: 25 OFFSET: -1 OBJECT: null NODE: null URL: null EVENT SEVERITY: 1 MESSAGE: cvc-type.3.1.3: The value 'Jane Doe' of element 'name' is not valid.

Practical XML: Parsing So you've built some XML, now what do you do? After all, it doesn't do you much good as a bunch of bytes on a disk.But in this example I used a Java String, which is UTF-16 encoded, without a prologue. The answer is that the parser did not read the string directly.Hi, my JAXB works fine when the input XML conforms with the schema. Do I need to write a custom Event Handler as means of a way out?But sometimes the input XML contains some extra non-business related fields (populated by the client application) that are absent from my schema definitions and cannot be predicted. Ideally I would want the parser to ignore such fields.
