Oracle收购BEA——如何看待J2EE中间件的价值

Oracle终于收购了BEA了
http://www.oracle.com/bea/index.html
http://biz.yahoo.com/ap/080116/oracle_bea.html

新一轮收购,其实最值得关注的是WebLogic/Tuxedo两个拳头产品,而作为一直缺乏中间件领头产品的Oracle公司,这一次又重新开始瓜分市场,微软/IBM/SAP都会面临直接的强有力的挑战。

整个事件中,对于所有JavaEE开发者,无疑是WebLogic。
如果说,Oracle是最优秀的数据库产品,我觉得,WebLogic绝对是铁定最优秀的J2EE中间件服务器(对WAS6.1,用户普遍认为还是WebLogic 9/10更强大)。
有很多人认为WebSphere会是一个挑战者,这里面含有较多的商业因素,从技术含量上,从稳定性,可靠性和关键企业用户覆盖上,WebLogic的价值远胜于WebSphere。在中国,WebLogic关键企业用户要远胜于WebSphere。
Oracle的中间件定义范畴非常广,这次的收购,在J2EE的领域,将会是新一场中间件标准的全面对抗,如果考虑到Oracle数据库曾经完胜了IBM的DB2一回,这一次,在J2EE中间件上,Oracle又一次是IBM抛离在脑后了。

在JavaEE中间件标准上,现在,Oracle有了Sibel,PeopleSoft,  BEA,在SOA Solution的完整性上,完全可以PK IBM了。

大部分人关注,现在的IT企业,架构越来越复杂,甚至SOA,曾经一度成为我们未来最重要的IT新概念,而J2EE本身,中间件本身,有些人甚至认为不再重要了,因为SOA是面向服务的,本身并不依赖于特定的J2EE中间件。
其实,明眼人还是能看出,所有的IT概念背后,IT的基础设施仍然是IT生态链中的关键组成部分,实施一个SOA的项目,你必须购买主机硬件,购买OS,购买中间件,然后最后才在其上开发你的SOA架构。
现在,SOA对抗,虚一点看,好像是IT战略的范畴,实一点看(从技术、资金),无非是平台之争。这一次Oracle收购BEA,足以让国人重新审视J2EE中间件的巨大价值和重要地位,WebLogic,目前,一个被IT500强公认为最优秀的J2EE中间件服务器,将会收购事件背后的其中一个主要的推动因素。无论SOA是如何成为第三波IT产业革命的重要推动力,J2EE中间件平台之争就犹豫当年的OS、浏览器之争那样激烈,是每个企业决策层实施SOA的时候必定考虑到的因素。

关于Weblogic GBK/GB2312/UTF-8乱码的问题

最近,频繁听到很多关于Weblogic乱码的问题,
其实,都是一些个人认为比较容易避免的问题。

1,如果是开发阶段的乱码,比如从屏幕上看到了一堆乱七八糟的编码
尝试在weblogic.xml文件的<jsp-descriptor>部分加入下面的描述:

  <jsp-descriptor>
       <jsp-param>
             <param-name>compilerSupportsEncoding</param-name>
             <param-value>true</param-value>
         </jsp-param>
         <jsp-param>
             <param-name>encoding</param-name>
               <param-value>GBK</param-value>
         </jsp-param>
  </jsp-descriptor>

这样,起码会告诉Weblogic容器你的应用含有中文,比如JSP页面,而它会善待你的JSP中的中文。


2,如果你是在Windows上面开发,然后部署到其他平台,比如IBM AIX上,则你要注意encoding的问题,
即文件的Encoding。比如,通常来说,各位都是Eclipse之徒,默认Eclipse上面的文件格式是基于本地的字符集,
即GBK,你是用GBK存储这些文件,甚至打包后想放到AIX上运行是不行的,解决方法太简单了,
JAVA_OPTIONS=-Dfile.encoding=GBK
告诉AIX上的Weblogic上的IBM JVM,默认文件encoding不是utf-8,是GBK, 即可。

上面两种方法,前者是针对中文编码的识别问题,后者是针对文件编码的识别问题,两者是不一样的。
在Java中,任何的内容都是以Unicode存在的,看Java程序中的内存,全部String都是Unicode,另外一个问题是,
假定这些String存储成文件,则要考虑Unicode如何写入到文件中,通常用的都是utf-8编码来存储。

关于Weblogic 10下开发WebService的配置问题

在Weblogic 10下面,weblogic.jar被拆分了,其中包括一些javax的接口被分解到api.jar去
所以,你发现自己的WebService无法解释下面这些引用,请务必加入api.jar。
import javax.jws.Oneway;
import javax.jws.WebMethod;
import javax.jws.WebResult;
import javax.jws.WebParam;
import javax.jws.WebService;

安装测试Apache Proxy For Weblogic Cluster笔记

请在下面的配置文档中置换以下三个字符串

BEA_HOME=D:\bea
APACHE_HOME=D:\Apache2
WEBLOGIC_CLUSTER=192.168.102.3:8001,192.168.102.4:8001,192.168.102.4:8003
 
 
配置文档:
1,Download Apache 2.0
http://httpd.apache.org/download.cgi

2,安装Apache 2.0, 使用默认的80默认端口
Copy Weblogic的so到Apache目录
源位置在:%BEA_HOME%\weblogic81\server\bin\mod_wl_20.so
目标位置在:%APACHE_HOME%\modules

注意改so文件已经包含了LoadBalence算法,可以通过Weblogic的Cluster去提供权重参数反馈给mod_wl_20.so,
这样, Apache知道如何Balance Request到Cluster中处理能力更强的服务器。

修改httpd.conf配置文件(%APACHE_HOME%\conf\httpd.conf),让apache加载weblogic提供的For Apache的Plugin——
LoadModule weblogic_module mod_wl_20.so
 
3,配置Apache指向Weblogic集群
让Apache遇到任何请求,都转发给Weblogic
<IfModule mod_weblogic.c> 
WebLogicCluster %WEBLOGIC_CLUSTER% 
MatchExpression *.*
</IfModule>

4,集群测试
在weblogic集群上部署defaultWebApp
直接访问http://localhost/defaultWebApp
Apache即可重订向用户到Weblogic集群去。

建议:对于静态资源,我们可以配置让Apache去读取并解析,无须Proxy到Weblogic集群去。

BEA Systems' Guardian Offers Pre-emptive Support -- eChannelLine.com
December 22, 2006 -- BEA Systems Inc. plans to release its BEA Guardian evaluation version followed by a general availability release. Guardian represents a departure from the traditional support model employed by the enterprise software industry and is designed to reduce the cost of reactive and proactive support services for organizations, officials said. Stuart Charlton, head enterprise architect for BEA Systems Canada, said his company is offering pre-emptive support as a means of analyzing the customer's computing environment and comparing it to BEA's knowledge base. The end result is Guardian is designed to detect problems before they occur and in turn help lower daily IT operational costs.

BEA Systems' Guardian Offers Pre-Emptive Support -- eChannelLine.ca
December 22, 2006 -- BEA Systems Inc. plans to release its BEA Guardian evaluation version followed by a general availability release. Guardian takes support services from a traditional break-fix model to a pre-emptive model, designed to help customers running business critical applications, given high availability is no longer a strategic goal but a tactical necessity in the modern world. "We're seeing a drive to reduce the diagnosis and time to resolution costs in the enterprise data centre," said Stuart Charlton, head enterprise architect for BEA Systems Canada. "This is another way of capturing knowledge in a machine-readable form and help resolve issues before they become problems."

Red Hat 3Q Profit Drops But Beats Wall Street Expectations -- San Jose Mercury News.com
December 22, 2006 -- Stock-compensation expenses cut into profits for the second consecutive quarter for Red Hat Inc., but the company again exceeded analysts' expectations. The company's second-quarter profit dropped 34 percent on stock-compensation expenses. But company shares surged nearly 14 percent in after-hours trading Thursday. "Our brand and our reputation is world-recognized," Red Hat Chairman Matthew Szulik said after markets closed. "The continued innovation in the next quarter will allow us to compete successfully."

Red Hat Earnings Shrug Off Oracle Threat -- ZDNet.com
December 21, 2006 -- Red Hat's net income subsided in its most recent quarter, but revenue increased as the Linux seller shrugged off the arrival of Oracle as a direct competitor. For the quarter ended November 30, the company's net income was $15.5 million, down 37 percent compared with the same period a year ago. But its revenue increased 45 percent to $105.8 million. The net income of 14 cents per share, excluding various charges like stock option expenses, beat the average expectation of 12 cents per share predicted by analysts surveyed by First Call. "It looks like the world is not coming to an end for you guys after all," said Merrill Lynch analyst Kash Rangan shortly afterward.

Customer Backlash Against Oracle's Buggy Linux Product? -- SeekingAlpha.com
December 22, 2006 -- Mark Murphy, an analyst for First Albany, asked "So, I guess the question is, is it realistic to think that Oracle is just going to ride this experiment into the ground, or would you expect them to possibly withdraw their offering from the marketplace?" Matthew Szulik, CEO Red Hat, responded "we're focused on the success of our customers. We are focused on expanding the opportunity for open source software through initiatives like OLPC with RHEL 5, RHN 2.0, the expanding JBoss middleware stack, and I have to be frank with you, I don't spend a whole lot of time thinking about the operational issues and the Oracle operating system product."

SAP Fills Out 2007 Agenda -- InternetNews.com
December 22, 2006 -- At the top of SAP's agenda is the SOA initiative, its new Duet software for Microsoft Office users, and an enterprise search service still in development. SAP's answer is to provide a standard platform based on its NetWeaver software on which to allow customers, ISVs, and others innovate. While most platform vendors let customers innovate to some degree, analyst Joshua Greenbaum credits SAP for running more forcefully with the idea. "Some of SAP's competitors are known for predatory partnerships, where you also have to compete with them, and I think SAP used to be more like that too," Greenbaum, who is with Enterprise Applications Consulting, told internetnews.com.

Key Developer Quits Novell Over Microsoft Patent Pact -- eWeek.com
December 21, 2006 -- Jeremy Allison, a leading Samba developer and well-known open-source speaker, has decided to leave Novell because of his objections to the Microsoft/Novell patent agreement. In his public letter of resignation, Allison said, "This has been a very difficult decision, but one I feel I have no choice but to make. My main issue with this deal is I believe that even if it does not violate the letter of the license it violates the intent of the GPL license the Samba code is released under, which is to treat all recipients of the code equally."

Wall Street Beat: The Year Ahead -- InfoWorld.com
December 22, 2006 -- Get set for some surprises. With 12 months of moderate expansion expected in the global IT arena, vendors will have to get creative in 2007 to maintain the kind of growth investors want. Tech companies, however, are under pressure. Worldwide IT spending will increase by 6.6 percent in 2007, according to IDC. This is slightly better than the 2006 increase of 6.3 percent but nowhere near the double-digit levels of the dot-com boom. "You will see major vendors performing unnatural acts," quipped Frank Gens, senior vice president of research at IDC.

Feature Story

The Traditional ESB Gets Weaved Into An SOA Fabric -- SearchWebServices.com
December 21, 2006 -- In a sign of how quickly things change, the "traditional" enterprise service bus is undergoing an evolution to stay current with the demands of the service-oriented architecture, morphing from an integration/messaging tool to an infrastructure offering that includes tools for business process management (BPM) and governance, analysts say.


The introduction this week of webMethods Fabric 7.0 indicates how much the ESB product category has grown from its original integration backbone role.


"The thing that we see in webMethods Fabric 7.0 is a really straightforward development environment for building composite applications in an SOA fashion," said Bill Swanton, vice president of research for AMR Research, Inc. He said the new product integrates all the tools historically linked to integration including the original enterprise application integration (EAI) technology as well as ESB, but now includes BPM, business activity monitoring (BAM), registry/repository and governance capabilities.


Outmoded as EAI may appear to be in an SOA world, it is still important to support the legacy technology, which is still in place in many corporations, said Peter S. Kastner, vice president enterprise integration for the Aberdeen Group.


"We found almost nobody who is willing to abandon their investments in EAI just to buy an ESB to say that they own one," he said. He cited webMethods as an original EAI company that has successfully made the transition into the SOA world while providing a bridge back to old integration technology. His research of IT departments this year disproved his own belief that the old integration vendors were doomed.


"My hypothesis going into the year was that the EAI companies would take it on the chin," Kastner said. "The reality is the vast majority of their customers are fairly easily connecting SOA via adapters to their EAI fabric or infrastructure."


Kastner and Swanton agree that adding the newer technology, especially BPM, is important to the evolution of the ESB technology webMethods is packaging under its Fabric brand.


Swanton said many of the other ESB vendors are still trying to put together a comprehensive toolset that will serve the needs of both business analysts and developers. The overall ESB technology is moving to include BPM so that developers can work with business analysts on the applications for the business processes, he said.


The BPM technology is important, Kastner said, because based on his research big business is embracing it in a big way. "We're seeing at this point that roughly 50 percent of the Global 5000 are actively engaged in business process management development." He noted that webMethods is not alone in integrating BPM into its ESB technology.


"You should note that Tibco has invested heavily in BPM over the last several years," he said. "Fiorano also beefed up their ESB product significantly in the BPM space in the last six months."


ESB evolution requires a new definition and perhaps even a new name, said Marc Breissinger, CTO at webMethods Inc., noting that the industry is beginning to embrace the term "fabric," which his company and some others use in their product branding.


From webMethod's point of view, the CTO said, the definition of ESB has expanded from a set of categorical definitions of features and functionality to a general category of technology that solves business problems.


"The focus of webMethods Fabric 7.0 coming out this week has to do with the evolution of business process management systems in the context of SOA and classic integration scenarios," Breissinger said. "What we have seen is a convergence of the straight-through processing style automated BPM along with the more human-centric approaches to business process management, or what is commonly referred to as workflow, into a coherent whole, along with business activity monitoring that also needs to be delivered by the BPMS, as well as UI development."


The term fabric has become the umbrella for all the added tools and technologies. It is also used by the Burton Group, which uses terms such as middleware fabric and Web services fabric in discussing application integration using the service-oriented approach.


Breissinger said he isn't wild about the fabric terminology, but it appears to be the best way to describe the holistic approach to combining ESB with BPM and other technology for measuring, modeling and implementing SOA.


"In the past before we got into the BPM space, we were talking about integration backbones," the webMethods' CTO said in providing a brief history of terms. "Then we talked about services buses. In a sense the fabric is the same concept taken one step further to include the business process management and the analytics and the composite application development capabilities to give you that full system building infrastructure versus a pure bus or backbone."
