Multi-Level Object Validation

[Ratzzak]

I'm currently using JSR-303 Bean Validation API for validating the bean.

I did a small program wh just primitive types.
Book.java

public class Book
{
	@NotEmpty
	private String name;

	@Size(min=1, max=50)
	private String description;

	// Getters and setters here
}

form.jsp

<form:form method="post" action="book.html" commandName="book">
	<table>
		<tr>
			<td>Name:</td> <td><form:input path="name" /></td> <td><form:errors path="name" /></td>
		</tr>
		<tr>
			<td>Description:</td><td><form:textarea path="description"/></td> <td><form:errors path="description" /></td>
		</tr>
		</table>
	<input type="submit" value="Create" />
</form:form>

Everything was working fine.

Then I introduced an object Author inside book.
Book.Java

Public Class Book{
	@NotEmpty
	private String name;
	@Size(min=1, max=50)
	private String description;
	private Author author;
	//Getters and Setters
}

Author.java

Public Class Author{
	@NotEmpty
	private String authorName;
	//Getters and Setters
}

Now I get an error:

javax.validation.UnexpectedTypeException: No validator could be found for type: com.ratzzak.form.Author

What is the right way to do the validation?

I suggest referring to the JSR 330 spec and/or documentation for your provider, but I believe adding @Valid to your author property on your parent bean is required. I'd research when that error you got can be thrown.
