Coming back from JBoss Two

03-06-12 Jevang
Spent a whole day at JBoss conference, which was just across the street of JavaOne venue, it is my first time with jboss event but it’s no doubt to me that it is better than any Java sessions I have attended before in past years( just one exception, its Floyd Marinescu’s presentation about j2EE pattern two years back)

Though I am not good at articulating things but I do want to share some interesting things in this JBoss event with folks here.

Impression on Marc Fleury
“Flamboyant”. That’s what I heard about him, my first look at him reminded me about Hitler, actually there is no facial similarity between them but probably his semi skin head let me think of Nazi. But when he opened his month, his image became the God Father of Italian mafia, the tone he spoke, the gestures used, of course he was speaking English with little bit French accent. Don’t get me worry, he is very good, quite a techi and business savvy person. He gave the first speech on JBoss open source and cool stuffs in JBoss4.0, did a fantastic job to elaborate how AOP is done in Jboss4, he even claimed JBoss is on the side with .NET vs. other J2EE vendors on the other side in term of simplicity, quite a few time he acknowledge .NET for it useful/practical approaches on metadata and declarative nature and easy of use. ( This does not mean .NET is ahead of game, jdk1.5 tiger is on the way remotely, at present, JBoss is standing out )

Follow up his introduction is a show up of JBoss start team members, it’s nice to see them all, but I just don’t want to say too much here.

Then two JBoss partners went on to introduce their integrated products with JBoss, a distributed JMS product and a JMX based JBoss specific performance monitor, I actually missed the most of the second part, as I stayed outside to chat with the CTO Dave and chief architect Mark from that JMS vendor about distribution transaction implementation and webservice. Actually there is a story behind to get me into it this topic:
http://www.jdon.com/jive/thread.jsp?forum=121&thread=7427

Next speech is from CTO of Intellij, my favoriate IDE, he gave some inside info about IDEA4.0 and another product which in the category to compete with BEA workshop or WASD, maybe English is not his native language, sometime I feel hard to concentrate on what he said, but it did show good stuffs are piled up for next version. Such as AOP support.

To me, the customer panel session is just marketing campaign, about 7 customers share their experience of using Jboss(good) vs. other vendors( not that good of course). During the break, I did find a chance to speak with Marc in person to thank him and JBoss for providing such as wonderful product which I can used in my project.

The AOP panel, IMHO, was the most delighting session in the day, Bill, CTO of Jboss , a guy from IBM and a professor from Japan gave individual speech about their view about AOP and their idea about declaration of Aspect and implementation, sometime they don’t see eye to eye with each other, mixed with different voices from the audiences, the session was quickly turned into a debate forum, Marc was like hosting a talk show, quite entertaining actually.
AOP is still new, personally I am quite happy to use it in logging, XML parsing, and I have been thinking to implement security cross cut using aspectJ, but the extensiveness of using AOP really make me mouth wide open for a while: tracing, security, transactional, caching( clustered) and persistence etc, Bill gave a live demo and I am convinced.

The end session is about JBoss Group, a professional organization and it’s about how JBoss make money, I like their business model to leverage service to keep the company running and get core developed paid so they can work on full scale. This further valid my concern about pure open source: A legitimate/long term business has to be self sustainable; it can’t be free for everything. Customer also looking for paid service to get better support.

I have been thinking all the way home about the upcoming JBoss server, the concept of POJO( plain old java object, which is going to be popular in jboss community soon),AOP and clustering JMS/Caching, comparing those technologies with my own development suite Topas, though they are still vague, for sure there are lots of territories to be explored with what I have learned today. Today, I just stop here.

Cheers

JBoss认为他们的目的和微软一样,用复杂的理念AOP把Jboss 4.0做好,使用者却比以往更方便的使用J2EE.

Marc 说, AOP是一次Travel,写aspect是复杂的,但是用却是简单的,应用系统的开发者不应该关心J2EE系统,他们只要建立针对实际应用的系统。

我认为这个口号喊了一段时间,目前比较接近了,我本人一直基于Jboss 3.0 + MySQL开发了几个成熟的J2EE项目,包括这个论坛也是运行在Jboss+Tomcat的平台中,每日刷新率是非常高的,可以参考页面下的统计,这种访问量足以相当一个中型系统的负荷,也就是说,在Jboss平台上,J道平台已经7/24稳定运行了一年。

这次Java大会上,Marc他们一直在强调 “OpenSource is Safe”, 我的经验证明,OpenSource has no problem! WonderFull, 我们为什么要花那么多银子给IBM和BEA买自己都感到惧怕的一个陌生体系?

我最近一直收到关于Webpshere培训的垃圾广告,我觉得真是可笑,websphere和weblogic对于我来说就相当于欧洲的贵族一样,如果你有点小资,那么无疑你是这类商品文化的牺牲者。

自己动手,J2EE没有什么秘密,只不过被一些人搞得太玄。

除了JBoss 4.0 和AOP的突然来到眼前比较让人吃惊外,这次Java大会其它亮点都是之前已经有过讨论:

EJB 3.0将更加容易使用,一个简单的HelloWorld Stateless Session bean包括所有必须的方法,以及home和remote接口,以及部署文件等。这些所有的将在EJB3.0中被5行??? 代替。

J2SE 1.5 猛虎要下山,相比微软Windows平台不断漏洞百出的安全问题,Java成熟应用到那么多领域,很少有类似事情发生,J2SE1.5继承这个良好的特性 继续在security上迈步向前,关于安全问题,国内很多人一直不足够重视,那么因为在他们思维的框架底部,没有互联网 TCP/IP这个概念,他们的思维和决定还是构造在封闭的隔绝的内部网,这种思维方式决定了他们大捧bill gates的臭脚。

最近在程序员杂志上看到一个不知什么公司的老总小捧自己:我很早就想有个语言能在虚拟机中运行,Java果然诞生了,我又想能编译在本地语言,C来了,还是Bill高明阿。我让进我公司的人,不论以前做什么,都改为.NET(我看到它公司的都是大学毕业生,重新开始学.NET)。

整个谈话中,没看到他肯定Java,唯一肯定的一句话是:我们软件产品是把.Net的东西放到Java上运行,为什么说这句话肯定Java? 因为他的潜台词是说:放在Java运行让我放心,而且安全成熟,言外之意是.NET做了那么多年平台,在企业应用的安全成熟上是失败的。

很可笑的一个人让他掩没在Java大会沸腾的欢庆声中吧!

程序员上面的那篇文章,我也看了。那家伙确实有点信口雌黄。

我有个问题,我没有用过JBoss,但是好像它和标准的J2ee有点区别,这样以前写的EJB组件是不是要修改啊!!我是看上他运行速度快了,向把Weblogic下面的转移过去试试

在JBoss上部署J2EE很简单,把.ear .war ejb-jar放到deploy目录就可以了,前提是你没有使用container的服务,例如data source,jndi等等。如果有,把原来的weblogic.xml用相应的jboss-service.xml替代就可以了。

Sun没有给jboss颁发j2ee兼容认证,但是原因可能不是技术上的。

我是《程序员》杂志记者闫辉

那篇《Java/.Net时代的选择》是我组织的。

我觉得各位说话有些偏颇,廖恒毅是国内最早的资深程序员,中文之星2.0就是他开发的,他曾经是微软的软件开发工具推广的部门经理。虽然他一直是在微软的平台上,但不能因为这个就否认其开发能力,佳软开发的ERP核心就是他用.NET开发的,各位想想,你们有没有用.net开发过一套能够在全国多家大公司实施的产品。(有些项目数千万)

我认为,各位不能就凭借一篇文章中的说法就否定一个人或者对其进行攻击。毕竟李维老师写过书,而胥国栋先生也担任公司CEO多年,而廖恒毅只是一心投入开发的环境中。

希望和各位进行探讨,谢谢!

是闫辉,我今天刚才你那儿串门回来,才发现你也来我们这儿串门来了,呵呵,欢迎啊。

有点请你能理解,咱们讨论是对事不对人,咱们本来准备是撇开具体人谈这事,谁知有人插嘴指名道姓了,这是不好,我替他们道歉。

这三位都是中国程序员的资深人员,组织他们的对话是非常有益的,下次再组织对话也从我们这里挑个人去,这样代表各方技术,是不是?呵呵。

我觉得banq兄对微软好像有很大的偏见,虽然我也是Java Fans,也不是很喜欢微软的东东,但是我认为现在网上普遍对微软的批评有点过了,或许在这里帮微软说话有遭版砖的危险,但是我还是认为微软仍然是值得尊敬的公司。我们做项目只从满足用户需求出发,不管使用何种技术、何种架构,能够尽可能满足用户需要、解决用户问题的系统就是好的,毕竟大家都不想做出系统孤芳自赏吧

我是当代天才的作曲家,贝多芬的音乐我早就想过了,果然贝多芬写了。

我是当代天才的画家,类似凡高的画我早就想画了,一看凡高那厮早画了。

我是廖天才,类似Java的技术及C#技术的思想我早就有了,果然SUN及不争气的微软作出来了,气愤呀气愤,我未公开的思想被别人盗用了。

我是天才的数学家,现在宣布歌德巴赫猜想我已想好如何证了,任何证出的人都是盗用了我的证明。要问我的证明在哪? 保密:)

我们为什么用jboss不用weblogic?
因为jboss免费,而jboss的人又想靠jboss赚钱。对我们来说不是个好消息。
另外,banq你说jdon是jboss+tomcat做的, 但是tomcat的性能好象不太好,你是怎么做到的?怎么配置的? 用的是什么硬件?谢谢。
