JakartaEE: Transformer: Support updating bean validation constraint mappings.

[nmittles]

Bean Validation can have XML configuration files that reference javax.validation.constraints.* constraint classes. These XML files are references from the main bean validation deployment descriptor named validation.xml.

The transformer tool needs to be updated to:

1. locate the bean validation validation.xml deployment descriptors

• WEB-INF/classes/META-INF/validation.xml (war module location where META-INF/validation.xml is available from the classloader)
• WEB-INF/validation.xml (non-spec, but Liberty supported war module location)
• META-INF/validation.xml (ear and jar location where META-INF/validation.xml is available from the classloader))

2. scan the validation.xml for <constraint-mapping> tags
3. load the xml file(s) referenced by the <constraint-mapping> tag(s)
4. update any references to javax.validation.constraints.* in these xml contraint mapping files

For Testing:
From com.ibm.ws.beanvalidation.v11_fat/fat/src/com/ibm/ws/beanvalidation/fat/basic/BasicValidation_Common.java remove:

        if (JakartaEE9Action.isActive()) {
            beanvalidation_10War.move("/WEB-INF/constraints-house_EE9.xml", "/WEB-INF/constraints-house.xml");
            beanvalidation_11War.move("/WEB-INF/constraints-house_EE9.xml", "/WEB-INF/constraints-house.xml");
        }

From /com.ibm.ws.beanvalidation.v11_fat/fat/src/com/ibm/ws/beanvalidation/fat/ejb/EJBModule_Common.java remove:

        if (JakartaEE9Action.isActive()) {
            jar.move("/META-INF/constraints-house_EE9.xml", "/META-INF/constraints-house.xml");
            jar2.move("/META-INF/constraints-house_EE9.xml", "/META-INF/constraints-house.xml");
        }

Delete the no longer needed constraints-house_EE9.xml files from both applications.

Example validation.xml:

<?xml version="1.0" encoding="UTF-8"?>
<validation-config
    xmlns="http://jboss.org/xml/ns/javax/validation/configuration"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://jboss.org/xml/ns/javax/validation/configuration validation-configuration-1.1.xsd"
    version="1.1">
  <message-interpolator>beanvalidation11.CustomMessageInterpolator</message-interpolator>
  <traversable-resolver>beanvalidation11.CustomTraversableResolver</traversable-resolver>
  <constraint-validator-factory>beanvalidation11.CustomConstraintValidatorFactory</constraint-validator-factory>
  
  <!-- new in Bean Validation 1.1 -->
  <parameter-name-provider>beanvalidation11.CustomParameterNameProvider</parameter-name-provider>
  
  <constraint-mapping>WEB-INF/constraints-house.xml</constraint-mapping>
</validation-config>

Example constraint mapping xml. In this case the file is named constraints-house.xml:

<?xml version="1.0" encoding="UTF-8"?>
<constraint-mappings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://jboss.org/xml/ns/javax/validation/mapping validation-mapping-1.1.xsd"
  xmlns="http://jboss.org/xml/ns/javax/validation/mapping">
  <default-package>beanvalidation11.web.beans</default-package>

  <bean class="AValidationXMLTestBean" ignore-annotations="true">
    <field name="builder">
      <constraint annotation="javax.validation.constraints.NotNull" />
    </field>

    <field name="address">
      <constraint annotation="javax.validation.constraints.NotNull" />

      <constraint annotation="javax.validation.constraints.Size">
        <element name="min">5</element>
        <element name="max">80</element>
      </constraint>
    </field>
  </bean>
  
  <bean class="AValidationMixTestBean" ignore-annotations="false">
    <field name="builder">
      <constraint annotation="javax.validation.constraints.NotNull" />
    </field>

    <field name="address">
      <constraint annotation="javax.validation.constraints.NotNull" />

      <constraint annotation="javax.validation.constraints.Size">
        <element name="min">5</element>
        <element name="max">80</element>
      </constraint>
    </field>
  </bean>
</constraint-mappings>
