It's normal practice to import types from an external xsd file in WSDL like this:
<wsdl:types> <xsd:schema xmlns:xsd="htt... When you use <dynamic-wsdl> and have Commons XMLSchema on the class path, Spring-WS inlines the xsd in the wsdl. But that doesn't happen when you use <static-wsdl> . You can define a SimpleXsdSchema bean to expose the xsd: <?xml version="1.0" encoding="UTF-8"?> <beans x... where the bean id "hello" should match the schemaLocation attribute in the WSDL (without the .xsd suffix). But note that the SimpleXsdSchema does not inline the xsd. It only makes the xsd available via an HTTP URL. Alternatively, you can simply put the xsd file under the content directory of the webapp (just link any CSS or JavaScript). Anyway, that's a lot of manual...

In the bean validation API javadoc, for every constraint annotation, there's a corresponding .List annotation. For example, for @NotNull , there's @NotNull.List , for which JavaDoc says: Defines several @NotNull annotations on the same element What would you accomplish with multiple @NotNull annotations that you cannot accomplish with one @NotNull ? This is a test to reveal some of the facts. Change the Person class to:
package com.example; public class Person { ... Add another JUnit test ( src/test/com/example/TestPersonWithList.java ): package com.example; import java.util.Itera... As the test shows, a Person bean can never be valid because we are requiring that name must begin with Mr and Ms . One might think that the same can be accomplished by simply repeating the @Pattern annotation multiple times,...

Validation groups can be used to control which rules validation rules to run. A validation group can be identified by any Java interface (not class!). Multiple validation groups may be specified when validating.
In this example, I added a validation group named MyValidationGroup ( src/main/java/com/example/MyValidationGroup.java in Maven project):
package com.example;
public interface MyVal...
and added a @Size rule for a person's name, because my database can only store up to 15 characters for a person's name:
package com.example;
import javax.validatio...
Now validate Person with a JUnit test ( src/test/java/com/example/TestPersonWithGroup.java in Maven project):
package com.example;
import java.util.Set;
...
Test with " mvn clean test ". The rules where groups is not specified, which belong to the javax.validation.groups.Default group, are not executed with these tests.

A bean class may also be defined through composition. The validation rules of referenced beans are not automatically called when a composite bean is validated. You need to use the @Valid annotation to trigger cascade validation.
As an example, I create a class named AccountPerson2 , which contains a Person with the addition of an email field ( src/main/java/com/example/AccountPerson2.java in Maven project):
package com.example;
import javax.validatio...
Now validate AccountPerson2 with a JUnit test ( src/test/java/com/example/AccountPerson2Test.java in Maven project):
package com.example;
import java.util.Set;
...
Test with " mvn clean test " and you'll see that the validation rules of the Person class are executed when an AccountPerson2 bean is validated. Without the @Valid annotation, the validation rules of Person will not be called.

When a bean class inherits another class, the validation rules of the parent class is automatically executed when a child class bean is validated.
As an example, I create a class named AccountPerson , which inherits the Person class with the addition of an email field ( src/main/java/com/example/AccountPerson.java in Maven project):
package com.example;
import javax.validatio...
Now validate AccountPerson with a JUnit test ( src/test/java/com/example/AccountPersonTest.java in Maven project):
package com.example;
import java.util.Set;
...
Test with " mvn clean test " and you'll see that the validation rules of the Person class are executed when an AccountPerson bean is validated.
