在glassfish 4和wildfly 8 Final上不适用最新的Mojarra 2.2.5
Manfried Riem 说,我已经看到了关于此的多个错误报告,
确定这是一个EL问题,EL实现已经修复以解决这个问题
修复版本说2.2.5,它也在2.2.5的发行说明中说明,我错过了什么？
我曾经遇到过wildfly 8这个问题,但解决了包含$ WILDFLY_HOME/modules/system/layers/base/org/eclipse/persistence/main中的eclipselink.jar并使用资源root更新module.xml
<resource-root path="eclipselink.jar" />
并包括在我的ejb模块的POM.xml上
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>eclipselink</artifactId>
<version>2.6.0</version>
<scope>provided</scope>
</dependency>
这在Wildfly 8中运行良好.*.不幸的是,为Wildfly 9CR1采用相同的技术一直都没有通过以下日志:

假设我们有以下实体。
@Entity(name = "User")
@Table(name = "USERS")
public class User{
@Id
@GeneratedValue
private int id
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="NOTES_ID")
private List<Note> notes;
}
而 Dto 将是
@Mapper
public interface UserDtoMapper{
/** the INSTACE HERE **/
User fromDto(UserDto dto);
UserDto toDto(User user);
}
那么哪个可能是获取所有用户而没有 EJBException 的最佳方法，因为我正在获取他们懒惰？
编辑：解决方案
假设您有以下数据模型
@Entity(name = "User")
@Table(name = "USERS")
public class User{
@Id
@GeneratedValue
private int id
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name="NOTES_ID")
private List<Note> notes;
}
addresses但因为延迟加载（通过休眠或任何其他框架）最终会出现异常。此外，您可以忽略addressesfrom 被映射，如@Mehmet …
我是在Mac OSX上开发Java的新手.我想下载Java 7 EE SDK,以便我可以使用Java进行桌面/移动/企业开发.下载文件.sh(具体java_ee_sdk-7-jdk7-macosx-x64)是我不熟悉的.Java 7 SE SDK是一个.dmg文件,它是我期望的Enterprise Edition而不是.sh文件的格式.
.shvs .dmg).sh
文件？*注意:目前我在Mac上安装的唯一JRE是Apple版本,据我所知已被弃用.
我们有一个Java EE 7应用程序并使用Arquillian来测试东西.现在我们要检查当前登录用户的一些权限.我的问题很基本,如何在测试用例中登录用户？我读过ProgrammaticLogin在arquillian测试和嵌入式Glassfish,安全性和Arquillian问题上都没有用,但是没有明确回答.我目前的做法是这样的:
// Inject services etc.
@Test
public void testLogin(){
UserAccount user = new UserAccount();
user.setUsername("bob");
user.setPassword("bob");
userAccountService.save(user);
ProgrammaticLogin pl = new ProgrammaticLogin();
String realmName = "secureJDBCRealm";
try {
pl.login("bob", "bob".toCharArray(), realmName, true);
} catch (Exception e){
e.printStackTrace();
}
}
现在当我尝试运行它时,得到一个LoginException,声称我没有为"fileRealm"配置LoginModule.但是"fileRealm"不是我正在寻找的领域(我把它放在那里进行第一次测试,但后来我将其改为"secureJDBCRealm",这是我们为GlassFish定制的安全领域).我们arquillian-glassfish-embedded-3.1用于测试.
我在项目中使用JAVA SE 1.7和JAVA EE 7,
哪些是可用的服务器(商业/免费),它们将支持JAVA EE 7 web profile 2.1？(必需组件).我需要使用Servlet 3.1和CDI 1.1 ..etc.
JavaEE的-spec_WebProfile
我尝试使用JBoss EAP 6.1/Jboss 7,但我开始知道它将支持JAVA EE 6 web配置文件.(web-profile1,web-profile2)
我发现JAVA EE 7兼容服务器是GlassFish Server Open Source Edition 4.0,TMAX JEUS 8.
还有其他服务器？
我已将我的应用程序从JSF 1.2迁移到2.2.
它在java.sun.com域 上使用XML命名空间xmlns:f="http://java.sun.com/jsf/core".但是,Oracle的Java EE 7教程正在使用xmlns.jcp.org域名
上的XML命名空间xmlns:f="http://xmlns.jcp.org/jsf/core".
推荐哪一个,为什么会改变？
EclipseLink 2.6.1(final)在GlassFish Server 4.1上部署Java EE应用程序时抛出以下异常.在从2.6.0升级之前没有发生这种情况.

//Here I start a comp.Future without giving an Executor
test = CompletableFuture.supplyAsync(() -> timeConsumingMethod());
//Here I start a parallel stream
mList.paralell().filter(...).collect(Collectors.toList())

我已经使用Java EE 7提供的api实现了一个WebSocket.此外,我已经实现了一个请求我的WebSocket没有任何问题的客户端.为了确保在执行某些代码更改时这仍然有效,我想实现测试,这些测试也可以在构建服务器上运行,例如Jenkins CI,而不仅仅是在本地.我正在使用maven.
