Performance Flexibility, MAKE A BALANCE!80-20 principle: 20% of the code uses 80% resource.20% of the code executes 80% of the time.KISS law: Keep It Simple & Small!Use independent resources like poolsReduce unnecessary distribution and transactionsPush the multiple SQL statement operation to the DB level.

Premature Object CreationDefine objects in the scope that needs them. Allocation, and construction use cycles, and, may require garbage collection to do extra work. Reconstruction is the absolute worst situation! Dont fall back on C/C++ techniques.

void f() {int i;Date x = new Date(); // Date x is constructed... // ...outside the scope where...// ... it is used...if (...) { .... // Date object x only used here }...}void f() {int i;...if (...) { Date x = new Date();// Date x is constructed...// ...inside the scope where...//... it is used ...// Date object x only used here }...}

Dont Initialize more than oncepublic class X { // member v is initd twice private Vector v = new Vector( ); public X( ) { v = new Vector ( ) }}public class Y { // member v is initd once private Vector v = new Vector( ); public Y( ) { }}

Time to construct 100,000 objects

Buffered I/OWhich is more efficient? - Given -PrintWriter pw = new PrintWriter( new BufferedWriter( new FileWriter(junk.out)));

printWriter.print(one + i);-or-printWriter.print(one );printWriter.print(i);

String & StringBufferMany hidden pitfalls exist for the novice to intermediate programmers.

String s = new String();long start = System.currentTimeMillis();for (int i = 0; i

Sockets vs RMI No time limit No Disqualifications! Sockets The assembly language of distributed programming. RMI Easier, but at what price?milliseconds

BEA WEBLOGIC SERVER Thank You

In addition to the applications rich business functionality, there are these critical infrastructure requirements that customers expect application server to provideNow lets look more closely at the WebLogic Enterprise Platform. The WebLogic Enterprise Platform is built on the latest release industrys leading application server, WebLogic Server 8.1, providing a robust, industrial-strength foundation for the platform. WebLogic Server also includes JRockit, the industrys first JVM designed specifically to address the unique requirements of server-side Java applications.

The WebLogic Enterprise Platform also includes WebLogic Integration for application and process integration. WebLogic Integration is a robust application integration framework for accessing, integrating, and exchanging information between packaged applications, legacy and custom applications, and multiple corporate data sources, and a full featured process engine to manage multi-step, long-lived business processes (including human workflow tasks) into one seamless flow that matches the business.

Liquid Data for WebLogic provides the data integration capabilities needed for improved business visibility with simplified access and aggregation of distributed business information.

For user integration, that is connecting people to processes and extending user access to business applications and processes on the WebLogic Enterprise Platform, WebLogic Portal provides an enterprise portal that simplifies, personalizes, and lowers the cost of customer, partner and employee access to information, applications and business processes.

And finally, development across the platform is unified with the simplified development model provided by WebLogic Workshop 8.1, with its integrated development environment and application framework framework that makes it incredibly easy for any developer not just J2EE experts to build, test, and deploy applications on the BEA WebLogic Enterprise Platform. On ant-driven tools: they provide high and low granularity access to Web Services generation utilities in order to allow both step-by-step or complete generation of Web Services. Low level tasks could generate the client proxy (including possible asynch invocations), test harness, SOAP router, custom user type proxy, WSDL file, Java proxy for a Web Service, or the complete Web Services package ready for deployment. In the future releases these tools will be accessible through centralized application building interfaces.Develop and extend applications quicker and easierAccess- Directly access native data sources to retrieve and aggregate dataUse- Developers can rapidly utilize unified views of information across multiple projects and deploy new applications quicklyDeliver- The complexity of getting data is now transparent, developers save time and costs by using a single API to access all enterprise data, regardless of where it residesData Services as part of a Service Oriented Architecture (SOA)Easily create composite views or data services as part of a Service Oriented Architecture (SOA) to design and assemble applications from services components Published once, data views can be reused and shared many times across multiple applications, thereby improving data consistency De-couple your business logic from enterprise data accessFlexibility to adapt to change Data is tagged and organized as metadata, so its easier to incorporate changes without the complexity of knowing each underlying data sourceThe Java Web Service Container generates:Stateless session beans to manage the requests to the application 1 per web serviceEntity beans to manage conversation state 1 per conversationMessage-driven beans to pull requests from message buffers and the JMS transport 1 per web service.

The container:Compiles the sourcePackages up the EAR fileGenerates the deployment descriptorDeploys the J2EE application to a running instance of WebLogic ServerGenerates a test harness application and traces the SOAP messagesGenerates the WSDL for the Web Service, and for its clients if there are client callbacksGenerates code for a Java proxy to the Web Service that can be used by development teams building clients in Java.

The web application generated for the Web Service by the container also exposes the WebLogic Server administration console to allow monitoring and management of the J2EE components generated to support the application.Extensible administration and management interface Administration console can be extended to report on application-specific set of metrics. WebLogic Server management can be integrated with the industry leading administration and management solutions. Through the same open API, your WLS-based application can be programmatically controlled from another application, or a batch. One more very important point administration service compatibility with prior and future releases. This means you can rollout a new release of WLS in phases, or just mix and match different releases in your environment while managing them from a single administration console.Extensible administration and management interface Administration console can be extended to report on application-specific set of metrics.

However, you can also find a wide range of classes on J2EE, Web Services, and other related technology both from BEA, and from other education vendors (like the Middleware company, who by the way us WebLogic Server as their education platform and to power their web site as well).Another good source of WebLogic-related information for developers is WebLogic Developer JournalAnd of course, no other J2EE product is so well represented in books as WebLogic Server. These books do a great job of a real deep drill down into development, administration, and other issues.
