JSF 1.2

EAP 7不支持JSF 1.2，可从EAP 6将JSF 1.2 Module(包含javax.faces.api，com.sun.jsf-impl，org.jboss.as.jsf-injection)迁移过来，module.xml内容无需更改，建议修改一下module版本urn:jboss:module:1.5
如部署使用的ear包，在jboss-deployment-structure.xml中增加如下配置：

<jboss-deployment-structure>
<deployment>
    <exclusions>
        <module name="javax.faces.api"/>
        <module name="com.sun.jsf-impl"/>
        <module name="org.jboss.as.jsf-injection"/>
    </exclusions>
    <dependencies>
        <module name="javax.faces.api" slot="1.2" export="true"/>
        <module name="com.sun.jsf-impl" slot="1.2" export="true"/>
        <module name="org.jboss.as.jsf-injection" slot="1.2" export="true"/>
    </dependencies>
</deployment>
<sub-deployment name="ejb.jar">
    <exclusions>
        <module name="javax.faces.api"/>
        <module name="com.sun.jsf-impl"/>
        <module name="org.jboss.as.jsf-injection"/>
    </exclusions>
    <dependencies>
        <module name="javax.faces.api" slot="1.2"/>
        <module name="com.sun.jsf-impl" slot="1.2"/>
        <module name="org.jboss.as.jsf-injection" slot="1.2"/>
    </dependencies>
</sub-deployment>
<sub-deployment name="web.war">
    <exclusions>
        <module name="javax.faces.api"/>
        <module name="com.sun.jsf-impl"/>
        <module name="org.jboss.as.jsf-injection"/>
    </exclusions>
    <dependencies>
        <module name="javax.faces.api" slot="1.2"/>
        <module name="com.sun.jsf-impl" slot="1.2"/>
        <module name="org.jboss.as.jsf-injection" slot="1.2"/>
    </dependencies>
</sub-deployment>
</jboss-deployment-structure>

Hibernate 3.5

强烈建议升级到Hibernate 5，如确实不能升级，需创建一个3.5 module，放入依赖包，module配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.5" name="org.hibernate" slot="3.5">
<properties>
    <property name="jboss.api" value="unsupported"/>
</properties>

<resources>
    <resource-root path="hibernate-core-3.5.6-Final.jar"/>
    <resource-root path="hibernate-entitymanager-3.5.6-Final.jar"/>
    <resource-root path="hibernate-annotations-3.5.6-Final.jar"/>
    <resource-root path="hibernate-commons-annotations-3.2.0.Final.jar"/>
    <resource-root path="hibernate-validator-3.1.0.GA.jar"/>
    <resource-root path="cglib-2.2.jar"/>
</resources>

<dependencies>
    <module name="javax.api"/>
    <module name="javax.annotation.api"/>
    <module name="javax.enterprise.api"/>
    <module name="javax.persistence.api"/>
    <module name="javax.transaction.api"/>
    <module name="javax.validation.api"/>
    <module name="javax.xml.bind.api"/>
    <module name="org.antlr"/>
    <module name="org.apache.commons.collections"/>
    <module name="org.dom4j"/>
    <module name="org.javassist" export="true"/>
    <module name="org.jboss.as.jpa.spi"/>
    <module name="org.jboss.jandex"/>
    <module name="org.jboss.logging"/>
    <module name="org.jboss.vfs"/>
    <module name="org.slf4j"/>      
</dependencies>
</module>

jboss-deployment-structure.xml中排除org.hibernate，引入3.5

<jboss-deployment-structure>
<deployment>
    <exclusions>
        <module name="org.hibernate"/>
    </exclusions>
    <dependencies>
        <module name="org.hibernate" slot="3.5" export="true"/>
        <module name="org.antlr" export="true"/>
        <module name="org.javassist" export="true"/>
    </dependencies>
</deployment>
<sub-deployment name="ejb.jar">
    <exclusions>
        <module name="org.hibernate"/>
    </exclusions>
    <dependencies>
        <module name="org.hibernate" slot="3.5"/>
        <module name="org.javassist"/>
    </dependencies>
</sub-deployment>
</jboss-deployment-structure>

修改persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0">
<persistence-unit name="schedule">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>java:jboss/datasources/scheduleDatasource</jta-data-source>
    <class>...</class>
    <properties>
        <property name="jboss.as.jpa.providerModule" value="org.hibernate:3.5"/>
                    <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
        ...
    </properties>
</persistence-unit>
</persistence>

HornetQ

EAP 7 使用了ActiveMQ Artemis取代了HornetQ，原Message-Driven Bean不需更改，需更改配置和客户端调用代码。

jms-destinations
EAP 6中jms-destinations配置如下：

<hornetq-server>
...
<jms-destinations>
 <jms-queue name="testQueue">
    <entry name="queue/test"/>
     <entry name="java:jboss/exported/jms/queue/test"/>
  </jms-queue>
</jms-destinations>
...
</hornetq-server>

更改为：

<server name="default">
...
<jms-queue name="testQueue" entries="queue/test java:jboss/exported/jms/queue/test"/>
...
</server>

security
如不启用security，增加如下配置：

<server name="default">
<security enabled="false"/>
...
</server>

org.apache.activemq.artemis module取代org.hornetq
修改客户端代码
EAP 7，默认connector从remote改为http-remoting，默认remote connection port从4447改为8080，PROVIDER_URL要从remote://localhost:4447修改为http-remoting://localhost:8080。INITIAL_CONTEXT_FACTORY从org.jboss.naming.remote.client.InitialContextFactory修改为org.wildfly.naming.client.WildFlyInitialContextFactory。
EAP 6:
```
java.naming.factory.initial=org.jboss.naming.remote.client.InitialContextFactory
java.naming.provider.url=remote://localhost:4447
```
EAP 7:
```
java.naming.factory.initial=org.wildfly.naming.client.WildFlyInitialContextFactory
java.naming.provider.url=http-remoting://localhost:8080
```
