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：

Richfaces 3.3

因EAP 7的servlet版本是3.1，fileUpload组件不能使用，需要使用getParts方法重写MultipartRequest实现。

    }
}

另外，Richfaces 3.3.4.Final fileupload组件页面显示有中文乱码问题，需要修改FileUploadRendererBase的initLabels方法，删除value = dumpingWriter.toString();这一行。

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：

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

修改persistence.xml

    org.hibernate.ejb.HibernatePersistence
    java:jboss/datasources/scheduleDatasource
    ...
    
        
        
        ...
    

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：

...

 
    
     
  

...

更改为：

 ...
 
 ...

security
如不启用security，增加如下配置：

 
 ...

Dependency

org.apache.activemq
artemis-jms-client
provided


org.jboss.spec.javax.jms
jboss-jms-api_2.0_spec
provided


org.jboss.spec.javax.json
jboss-json-api_1.0_spec
provided

org.apache.activemq.artemis module取代org.hornetq 客户端代码
EAP 7，默认connector从remote改为http-remoting，使用undertow default http-listener、http端口，这也是推荐的方式：

...


...

...

   
   
   ...

...

客户端代码要做以下修改：remote connection port从4447改为8080，PROVIDER_URL从remote://localhost:4447改为http-remoting://localhost:8080。INITIAL_CONTEXT_FACTORY从org.jboss.naming.remote.client.InitialContextFactory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

EJB Connector
EAP 7，默认connector从remote改为http-remoting，使用undertow default http-listener、http端口。

EAP 7:

java.naming.factory.initial=org.wildfly.naming.client.WildFlyInitialContextFactory
java.naming.provider.url=http-remoting://localhost:8080

Standalone Client
EAP 7.1引入新的配置文件wildfly-config.xml，统一了所有客户端的配置，在standalone client中推荐使用这种方式。wildfly-config.xml放在classpath或META-INF目录下，也可用-Dwildfly.config.url指定路径（优先级：wildfly.config.url > classpath > META-INF）。
wildfly-config.xml:

使用wildfly-config.xml时的Java代码：

Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, WildFlyInitialContextFactory.class.getName());
properties.put(Context.PROVIDER_URL, http-remoting://localhost:8080);
Context context = new InitialContext(properties);
Object theRemote = context.lookup(jndiName);
...

代码很简单，多个PROVIDER_URL时用逗号分隔。注意运行之前要添加ApplicationRealm用户：

add-user.sh -a -u quickuser -p quick-123

Server-to-Server
利用remote-outbound-connection，在standalone.xml中增加如下配置：
增加security-realm，密码需经Base64编码

    
        
            
        
    
    ...

...

配置remote-outbound-connection

配置Socket

...

    

在war的WEB-INF或ear的META-INF中新建文件jboss-ejb-client.xml：

Java代码

Properties props = new Properties();  
props.put(Context.URL_PKG_PREFIXES, org.jboss.ejb.client.naming);  
Context context = new javax.naming.InitialContext(props);  
Object theRemote = context.lookup(jndiName);

Seam 2.2.2.Final

seam 2.2可以运行在Jboss EAP 7，同在EAP 6中一样，需修改org.jboss.seam.transaction.Transaction：

protected javax.transaction.UserTransaction getUserTransaction() throws NamingException
{
  InitialContext context = Naming.getInitialContext();
  try
  {
     return (javax.transaction.UserTransaction) context.lookup(java:comp/UserTransaction);
  }
  catch (NamingException ne)
  {
     try
     {
        //Embedded JBoss has no java:comp/UserTransaction
        javax.transaction.UserTransaction ut = (javax.transaction.UserTransaction) context.lookup(UserTransaction);
        ut.getStatus(); //for glassfish, which can return an unusable UT
        return ut;
     }
     catch (NamingException nnfe2) {
         // Try the other JBoss location in JBoss AS7
         return (javax.transaction.UserTransaction) context.lookup(java:jboss/UserTransaction);
     }
     catch (Exception e)
     {
        throw ne;
     }
  }
}

如使用了seam-resteasy，需排除jaxrs子系统，使用EAP 6中的resteasy版本即可。

    
        
    
    ...

PicketLink 配置Subsystem

EAP 7默认是不支持picketlink的，需要配置picketlink subsystem。
增加extension

...

...

配置subsystem

...

...

配置security-domain

将EAP 6中相应配置迁移过来即可。

配置jboss-deployment-structure

    
        ...
        
    

注意：必须要添加services="import"。

配置Federation

EAP 7，valve不再使用：

sp

    org.picketlink.identity.federation.bindings.tomcat.sp.ServiceProviderAuthenticator
    
        characterEncoding
        UTF-8
    

idp
idp-sig

    org.picketlink.identity.federation.bindings.tomcat.idp.IDPWebBrowserSSOValve

删除valve，参数需迁移到web.xml中：

org.picketlink.federation.saml.CHARACTER_ENCODING
UTF-8

web.xml中必须配置login-config

...

FORM

注意：idp、sp都要配置auth-method
picketlink.xml sample:

    http://localhost:8080/idp-sig/
    https://localhost:8443/sso/
    
        
        
        
        
        
    


    
    
        
        
    
    
    
    

注意：

如果升级到EAP 7.1.2后使用picketlink可能会报如下错误：
Error during the logout.: java.lang.NullPointerException
at org.picketlink.identity.federation.bindings.wildfly.sp.SPFormAuthenticationMechanism.lambda$authenticate$0(SPFormAuthenticationMechanism.java:275)
建议7.1.3发布后再升级。 Undertow Servlet Container有一属性proactive-authentication，默认为true，会拦截所有含有SAMLResponse参数的请求。当项目中使用了其他custom portal时，将其设为"false";

Patching EAP

使用CLI应用、回滚、清除Patch

Applying a Patch

patch apply /path/to/downloaded-patch.zip --override-all
shutdown --restart=true

Rolling Backe a Patch

先使用patch history查询出patch id，然后调用rollback命令：

patch history
patch rollback --patch-id=PATCH_ID --reset-configuration=TRUE
shutdown --restart=true

Clearing Patch History

多次打Patch后会占用磁盘空间，可进行清理，但当前应用的Patch是不能删除的。

/core-service=patching:ageout-history
