java - ejb-jar.xml 环境条目枚举

Question

这是我的 ejb-jar.xml:

<?xml version="1.0" encoding="UTF-8"?>

<ejb-jar xmlns = "http://java.sun.com/xml/ns/javaee" 
         version = "3.0" 
         xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" 
         xsi:schemaLocation = "http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd">

    <enterprise-beans>
        <session>
            <ejb-name>EmailEjb</ejb-name>
            <env-entry>
                <env-entry-name>java:app/env/smtp.host</env-entry-name>
                <env-entry-type>java.lang.String</env-entry-type>
                <env-entry-value>smtp.mandrillapp.com</env-entry-value>
            </env-entry>
            <env-entry>
                <env-entry-name>java:app/env/smtp.port</env-entry-name>
                <env-entry-type>java.lang.Integer</env-entry-type>
                <env-entry-value>587</env-entry-value>
            </env-entry>
            <env-entry>
                <env-entry-name>java:app/env/smtp.transportStrategy</env-entry-name>
                <env-entry-type>org.codemonkey.simplejavamail.TransportStrategy</env-entry-type>
                <env-entry-value>SMTP_TLS</env-entry-value>
            </env-entry>
            <env-entry>
                <env-entry-name>java:app/env/smtp.username</env-entry-name>
                <env-entry-type>java.lang.String</env-entry-type>
                <env-entry-value>user@example.com</env-entry-value>
            </env-entry>
            <env-entry>
                <env-entry-name>java:app/env/smtp.password</env-entry-name>
                <env-entry-type>java.lang.String</env-entry-type>
                <env-entry-value>foobar</env-entry-value>
            </env-entry>
        </session>
    </enterprise-beans>
</ejb-jar>

部署后，我收到此异常:

org.xml.sax.SAXParseException; lineNumber: 23; columnNumber: 85; Deployment descriptor file WEB-INF/ejb-jar.xml in archive [localgp-web-1.0-SNAPSHOT]. cvc-enumeration-valid: Value 'org.codemonkey.simplejavamail.TransportStrategy' is not facet-valid with respect to enumeration '[java.lang.Boolean, java.lang.Byte, java.lang.Character, java.lang.String, java.lang.Short, java.lang.Integer, java.lang.Long, java.lang.Float, java.lang.Double]'. It must be a value from the enumeration.

这似乎表明，尽管 the documentation ，不允许使用枚举。或者是否发生了其他我可能错过的事情？

NetBeans 7.2.1(目前最新版本)为 EJB 规范 3.0 版生成 ejb-jar.xml，该规范不将枚举识别为 env-entry-type。将其更改为版本 3.1 可以解决问题并且资源可以正确注入(inject)。

<ejb-jar xmlns = "http://java.sun.com/xml/ns/javaee" 
         version = "3.1" 
         xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance" 
         xsi:schemaLocation = "http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd">

    <!-- Stuff goes here. -->

</ejb-jar>
