Oracle終于收購了BEA了
http://www.oracle.com/bea/index.htmlhttp://biz.yahoo.com/ap/080116/oracle_bea.html新一輪收購，其實(shí)最值得關(guān)注的是WebLogic/Tuxedo兩個(gè)拳頭產(chǎn)品，而作為一直缺乏中間件領(lǐng)頭產(chǎn)品的Oracle公司，這一次又重新開始瓜分市場(chǎng)，微軟/IBM/SAP都會(huì)面臨直接的強(qiáng)有力的挑戰(zhàn)。
整個(gè)事件中，對(duì)于所有JavaEE開發(fā)者，無疑是WebLogic。
如果說，Oracle是最優(yōu)秀的數(shù)據(jù)庫產(chǎn)品，我覺得，WebLogic絕對(duì)是鐵定最優(yōu)秀的J2EE中間件服務(wù)器(對(duì)WAS6.1，用戶普遍認(rèn)為還是WebLogic 9/10更強(qiáng)大)。
有很多人認(rèn)為WebSphere會(huì)是一個(gè)挑戰(zhàn)者，這里面含有較多的商業(yè)因素，從技術(shù)含量上，從穩(wěn)定性，可靠性和關(guān)鍵企業(yè)用戶覆蓋上，WebLogic的價(jià)值遠(yuǎn)勝于WebSphere。在中國，WebLogic關(guān)鍵企業(yè)用戶要遠(yuǎn)勝于WebSphere。
Oracle的中間件定義范疇非常廣，這次的收購，在J2EE的領(lǐng)域，將會(huì)是新一場(chǎng)中間件標(biāo)準(zhǔn)的全面對(duì)抗，如果考慮到Oracle數(shù)據(jù)庫曾經(jīng)完勝了IBM的DB2一回，這一次，在J2EE中間件上，Oracle又一次是IBM拋離在腦后了。
在JavaEE中間件標(biāo)準(zhǔn)上，現(xiàn)在，Oracle有了Sibel，PeopleSoft,?
BEA，在SOA Solution的完整性上，完全可以PK IBM了。
大部分人關(guān)注，現(xiàn)在的IT企業(yè)，架構(gòu)越來越復(fù)雜，甚至SOA，曾經(jīng)一度成為我們未來最重要的IT新概念，而J2EE本身，中間件本身，有些人甚至認(rèn)為不再重要了，因?yàn)镾OA是面向服務(wù)的，本身并不依賴于特定的J2EE中間件。
其實(shí)，明眼人還是能看出，所有的IT概念背后，IT的基礎(chǔ)設(shè)施仍然是IT生態(tài)鏈中的關(guān)鍵組成部分，實(shí)施一個(gè)SOA的項(xiàng)目，你必須購買主機(jī)硬件，購買OS，購買中間件，然后最后才在其上開發(fā)你的SOA架構(gòu)。
現(xiàn)在，SOA對(duì)抗，虛一點(diǎn)看，好像是IT戰(zhàn)略的范疇，實(shí)一點(diǎn)看(從技術(shù)、資金)，無非是平臺(tái)之爭(zhēng)。這一次Oracle收購BEA，足以讓國人重新審視J2EE中間件的巨大價(jià)值和重要地位，WebLogic，目前，一個(gè)被IT500強(qiáng)公認(rèn)為最優(yōu)秀的J2EE中間件服務(wù)器，將會(huì)收購事件背后的其中一個(gè)主要的推動(dòng)因素。無論SOA是如何成為第三波IT產(chǎn)業(yè)革命的重要推動(dòng)力，J2EE中間件平臺(tái)之爭(zhēng)就猶豫當(dāng)年的OS、瀏覽器之爭(zhēng)那樣激烈，是每個(gè)企業(yè)決策層實(shí)施SOA的時(shí)候必定考慮到的因素。
最近，頻繁聽到很多關(guān)于Weblogic亂碼的問題，
其實(shí)，都是一些個(gè)人認(rèn)為比較容易避免的問題。
1，如果是開發(fā)階段的亂碼，比如從屏幕上看到了一堆亂七八糟的編碼
嘗試在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>
這樣，起碼會(huì)告訴Weblogic容器你的應(yīng)用含有中文，比如JSP頁面，而它會(huì)善待你的JSP中的中文。
2，如果你是在Windows上面開發(fā)，然后部署到其他平臺(tái)，比如IBM AIX上，則你要注意encoding的問題，
即文件的Encoding。比如，通常來說，各位都是Eclipse之徒，默認(rèn)Eclipse上面的文件格式是基于本地的字符集，
即GBK，你是用GBK存儲(chǔ)這些文件，甚至打包后想放到AIX上運(yùn)行是不行的，解決方法太簡(jiǎn)單了，
JAVA_OPTIONS=-Dfile.encoding=GBK告訴AIX上的Weblogic上的IBM JVM，默認(rèn)文件encoding不是utf-8，是GBK, 即可。
上面兩種方法，前者是針對(duì)中文編碼的識(shí)別問題，后者是針對(duì)文件編碼的識(shí)別問題，兩者是不一樣的。
在Java中，任何的內(nèi)容都是以Unicode存在的，看Java程序中的內(nèi)存，全部String都是Unicode，另外一個(gè)問題是，
假定這些String存儲(chǔ)成文件，則要考慮Unicode如何寫入到文件中，通常用的都是utf-8編碼來存儲(chǔ)。

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."

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."
