1 Upgrading WebLogic Server 6.x to Version 7.0

Deployment

WebLogic Server 7.0 provides a new two-phase deployment model. For more information on this deployment model and other 7.0 deployment features, see WebLogic Server Deployment. By default, statically configured applications use the 6.x deployment model. Deployments initiated through the console or the new weblogic.Deployer command line utility use the new two-phase deployment model.

WebLogic Server 7.0 will not deploy an application that has any errors in its deployment descriptor. Previous versions of WebLogic Server would deploy an application that had errors in its deployment descriptor. For example, if your 6.x application was missing a reference description stanza in the deployment descriptor, the application will not deploy in the 7.0 server until you add that stanza. A typical stanza looks like:

<ejb-reference-description> <ejb-ref-name>ejb/acc/Acc</ejb-ref-name> <jndi-name>estore/account</jndi-name> </ejb-reference-description>

Using WebLogic Server 7.0, you can no longer deploy through the console using the 6.x protocol. As a result, you must use the new deployment APIs. If your application is previously deployed in 6.x and you’re just starting your server, the applications will get deployed with one-phase deployment. The weblogic.deploy and weblogic.refresh command line utilities and the

weblogic.management.tools.WebAppComponentRefreshTool are deprecated in 7.0.

See “Deprecated APIs and Features” on page 1-34 for information on deprecated MBean attributes and operations.

The applications in the applications directory in development mode on the Administration Server are now staged. In 6.x, they were not. For more information see Application Staging in the section called Two-PhaseDeploymentin Developing WebLogic Server Applications.

7 specifications

BEA 7, a significant product from BEA Systems, represents a cornerstone in enterprise application integration and service-oriented architecture. As a comprehensive solution for developing, deploying, and maintaining enterprise-level applications, it brings a host of features that cater to the needs of businesses seeking agility and reliability in their IT infrastructure.

One of the standout characteristics of BEA 7 is its robust support for service-oriented architecture (SOA). This enables businesses to create applications as loosely coupled services, facilitating easier integration and scalability. The platform's emphasis on middleware technologies allows organizations to streamline their IT operations, enhance interoperability, and reduce time to market for new applications.

BEA 7 includes a powerful application server that provides a reliable runtime environment for managing applications. Offering high availability and scalability, it can successfully handle the demands of high-volume transactions while ensuring optimal performance. The built-in clustering capability ensures that applications can remain operational even in the event of server failures, which is critical for mission-critical applications.

Another notable feature of BEA 7 is its capabilities for web services. With support for industry standards such as XML, SOAP, and WSDL, users can easily expose and consume services across diverse platforms. This allows businesses to take full advantage of an interconnected ecosystem and simplifies the process of integrating various applications and data sources.

Security is a paramount consideration in BEA 7, which includes strong authentication, authorization, and encryption mechanisms to protect sensitive data. The platform's comprehensive security features ensure compliance with regulatory requirements and protect against potential threats, which is particularly important for sectors handling sensitive information, such as finance and healthcare.

BEA 7 also embraces innovative technologies such as the Java EE platform, facilitating the development of cross-platform applications. The integrated development environment (IDE) offers numerous tools for developers, making it easier to design, debug, and deploy applications. Developers benefit from built-in support for commonly used frameworks and libraries, improving productivity and enabling rapid application development.

In summary, BEA 7 stands out as a powerful enterprise solution, distinguished by its support for SOA, robust application server capabilities, web services integration, strong security features, and a developer-friendly environment. These attributes make BEA 7 an essential tool for organizations aiming to enhance their operational efficiency and adapt to the increasingly dynamic business landscape.
