This software extends enterprise applications to a wide variety of devices with middleware that comprise versions of ibm enterprise software such as db2e, mqe, service management framework, and java runtime environments 該軟件將企業(yè)應(yīng)用程序擴(kuò)展到大量具有中間件的設(shè)備,其包含ibm企業(yè)軟件版本,如db2e、mqe、servicemanagement框架和java運(yùn)行時環(huán)境。
One javaranch discussion started out with the basic question " what should be the maximum heap size setting ? " before delving into the details, let s first go over the basics of memory management in the java runtime 在javaranch上有一次討論就是以“最大堆長度設(shè)置應(yīng)該是怎樣的?”這一基本問題開始的。在深入研究之前,讓我們先復(fù)習(xí)一下java運(yùn)行時中內(nèi)存管理的基礎(chǔ)知識。
Do not accept the default of installing under the program files directory . sun s java runtime environment on the client computer to match the j2sdk . the installation of any java 1.4 jre on a client computer should install the java web start client 如果您想要學(xué)習(xí)如何將j2se客戶端連接到運(yùn)行在ibmwebspherestudio平臺上的web服務(wù)或想學(xué)習(xí)如何使用javawebstart從webspherestudio部署j2se客戶端,您就應(yīng)該學(xué)習(xí)本教程。
It also designs the mechanism of realizing audio / video conference . in java runtime environment, a better method can be taken, this is to say, we expand the conception of jmfs " multiplexior ", getting the " audio mixer " object to manage the audio stream and getting the " video mixer " object and the " token click and preempt " control mechanism object to manage the video stream . at last this solution method gives afford the facts below : the quantities of persons who join the audio collaborate do not been restricted and people do not need a voice authority before they speak 本文還對音頻視頻協(xié)作會議內(nèi)部實(shí)現(xiàn)機(jī)制進(jìn)行了重新設(shè)計改進(jìn),給出一種針對java運(yùn)行環(huán)境的優(yōu)化實(shí)現(xiàn)方法,它對jmf中的復(fù)用器對象的概念進(jìn)行擴(kuò)展,引入“混音器”處理音頻流、視頻復(fù)用器和“令牌控制機(jī)制”處理視頻流,提供了不限用戶數(shù)量和是否擁有發(fā)言權(quán)條件限制的音頻協(xié)作手段,也提供了用戶數(shù)量及發(fā)送權(quán)受限的視頻交流手段。
The ibm software includes the apache derby code without any modification whatsoever and adds a few features you won t find in the apache derby software, such as user-friendly installers that include the java runtime environment, which are helpful for jumpstarting new java developers, and translated manuals 該ibm軟件包括未作任何修改的apachederby代碼,另外還添加了apachederby軟件中所沒有的一些特性,例如用戶友好的安裝程序,包括有助于剛?cè)腴T的java開發(fā)人員提高水平的javaruntimeenvironment(jre)和一些翻譯好的手冊。
This may be one of the reasons for the pervasive belief that object allocation is expensive-earlier jvm implementations did not use copying collectors, and developers are still implicitly assuming allocation cost is similar to other languages, like c, when in fact it may be significantly cheaper in the java runtime 以前的jvm實(shí)現(xiàn)沒有使用復(fù)制收集器這可能是對象分配是昂貴的這一想法是如此普遍的原因之一,開發(fā)人員仍然下意識地假設(shè)分配成本與其他語言(如c)類似,而事實(shí)上在java運(yùn)行時中可能要廉價得多。
To provide these features, workplace client technology consists of two general layers : the jre java runtime environment, which interacts directly with the operating system and provides basic core services, and the extension services layer, which provides user-facing features and services 要提供這些功能,workplaceclienttechnology需要包含兩個一般層:jre(javaruntimeenvironment),其直接與操作系統(tǒng)進(jìn)行交互并提供基本核心服務(wù),另一層是擴(kuò)展服務(wù)層,其提供用戶互動功能和服務(wù)。
