1 Upgrading WebLogic Server 6.x to Version 7.0
1-24 BEA WebLogic Server 7.0 Upgrade Guide
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-PhaseDeployment in Developing
WebLogic Server Applications.
