Q. How do I upgrade my Workshop applications to use one of the new Java 2 SDKs that are installed with the latest service pack?
A. You have a choice of two methods.
Note: To ensure that your Workshop applications have access to the latest updates and bug fixes for the basic Workshop domain, we recommend the second approach.
JAVA_HOME environment variable in your domain's setDomainEnv script (setDomainEnv.cmd or setDomainEnv.sh) so it points to the root directory of the SDK installed with the current service pack. For example: Q. Which feature changes in WebLogic Workshop 8.1 affect the upgrade process?
A. For a list of feature changes that affect the upgrade process, see "New Features in WebLogic Workshop" in "Upgrading Workshop Applications" in the WebLogic Workshop Help at http://download.oracle.com/docs/cd/E13226_01/workshop/docs81/doc/en/workshop/guide/migration/
conMigratingWorkshopApplications.html.
Q. How do I upgrade WebLogic Workshop applications to 8.1 from 7.0?
A. To upgrade your applications to WebLogic Workshop 8.1:
com.bea.jws.WebService interface.java.io.Serializable interface.WEB-INF/lib directory for your project, consider moving them to the APP-INF/lib directory in your upgraded application..java files or Java classes in the WEB-INF/classes directory for your project, consider moving them to the APP-INF/classes directory in your upgraded application.For more information about using the jwsUpgrade command, see "jwsUpgrade Command" in the WebLogic Workshop Help at http://download.oracle.com/docs/cd/E13226_01/workshop/docs81/doc/en/workshop/reference/commands/cmdJwsUpgrade.html.
For more detailed instructions on upgrading to WebLogic Workshop 8.1, see "Upgrading Workshop Applications" in the WebLogic Workshop Help at http://download.oracle.com/docs/cd/E13226_01/workshop/docs81/doc/en/workshop/guide/migration/conMigratingWorkshopApplications.html.
Q. How has the control model changed for WebLogic Workshop 8.1?
A. WebLogic Workshop 8.1 introduces a new, extensible model for controls. As in WebLogic Workshop 7.0, you can connect to enterprise resources using the built-in controls provided. In addition, with WebLogic Workshop 8.1, you can create your own reusable custom controls, making it easy to encapsulate business logic within your application.
When you create a control in WebLogic Workshop 8.1, the filename for your new control includes a JCX extension. The filename for a control created in WebLogic Workshop 7.0 includes a CTRL extension.
Q. What is the upgrade method for controls for WebLogic Workshop 8.1?
A. WebLogic Workshop 8.1 continues to support controls built using WebLogic Workshop 7.0. However, we recommend that you upgrade your existing controls to the new control model to take advantage of its greater flexibility.
com.bea.Control.ControlExtension interface. You may need to modify the control file in Source View in WebLogic Workshop to extend the interface.@jc prefix, rather than @jws, which is supported for 7.0.@common:control, rather than @jws:control, which is supported for 7.0.The following table summarizes the differences between the annotation style used in version 7.0 and that used in version 8.1 of WebLogic Workshop.
To find out more about specific annotation changes, open WebLogic Workshop, put the cursor on the annotation currently displayed in Source view, and press F1. Context-sensitive help for the designated annotation will be displayed.
For more information about upgrading databases, Web services, and JMS controls, see "Upgrade Controls" in "Migrating Your Existing Application" in "Upgrading Workshop Applications" in the WebLogic Workshop Help at http://download.oracle.com/docs/cd/E13226_01/workshop/docs81/doc/en/workshop/guide/migration/conMigratingWorkshopApplications.html#migrating.
Q. How do I upgrade WebLogic Portal applications to 8.1 SP5 from pre-SP5 releases of 8.1?
A. For complete details about upgrading your WebLogic Portal applications, see the following topics in the WebLogic Portal 8.1 Upgrade Guide:
Q. How do I upgrade WebLogic Portal applications to 8.1 from 7.0 SP2?
A. Choose either of the following methods to upgrade your portal Web application created with WebLogic Portal from 7.0 SP2 to 8.1:
For details, see the WebLogic Portal 8.1 Upgrade Guide at http://download.oracle.com/docs/cd/E13218_01/wlp/docs81/upgrade/index.html.
Q. Which WebLogic Portal 7.0 SP2 features work in the new 8.1 framework?
A. Which features work in the 8.1 framework depends on which method you choose for your upgrade.
Q. How do I use the Compatibility method to upgrade WebLogic Portal applications to 8.1 from 7.0 SP2?
A. WebLogic Portal 8.1 supports a Compatibility Domain to enable you to host upgraded WebLogic Portal 7.0 SP2 portal applications on versions of WebLogic Portal 8.1 through SP2. For more information about creating a Compatibility Domain and the steps required to upgrade an existing portal application to run in the domain, see "Version 8.1 Compatibility Domain" in the WebLogic Portal 8.1 Upgrade Guide at http://download.oracle.com/docs/cd/E13218_01/wlp/docs81/upgrade/chapter2.html.
Q. How do I use the Upgrade method to upgrade WebLogic Portal applications to 8.1 from 7.0 SP2?
A. To run a portal Web application developed on WebLogic Portal 7.0 SP2 in a WebLogic Portal 8.1 domain, perform the following steps:
Q. How do I upgrade portal and portal XML definitions from WebLogic Portal 7.0 SP2 to 8.1?
A. For instructions, see "Upgrading Database and Metadata Files from 7.0 to 8.1" in "Upgrading to WebLogic Portal 8.1" in the WebLogic Portal 8.1 Upgrade Guide at http://download.oracle.com/docs/cd/E13218_01/wlp/docs81/upgrade/chapter3.html.
Q. How do I upgrade portlets created in WebLogic Portal 7.0 SP2 to 8.1?
A. Depending on the complexity of the portlet, you may decide to copy the portlet resources (content JSPs and backing files) into the new application and re-create the .portlet file. Review the following topics for information on upgrading JSP, WebFlow, and Web Service portlets:
Drag the JSP file into a placeholder in a portal; the portlet is generated automatically. WebLogic Workshop identifies the JSP tags defined in the file that need to be replaced. For a summary of changes to the JSP tags, see "Framework Reference for Portal Upgrades from 7.0 to 8.1" in the WebLogic Portal 8.1 Upgrade Guide at http://download.oracle.com/docs/cd/E13218_01/wlp/docs81/upgrade/appendix.html.
For the 8.1 release, Web services are accessed using a Web Service control that you create using WebLogic Workshop. Once you create a page flow containing a control of this type, drag the .jpf file into a placeholder in a portal. Your Web service portlet will be created automatically.
Note: The Portlet Wizard no longer automates the creation of portlets that call Web services directly.
Q: How do I upgrade portal data from a WebLogic Portal 7.0 SP2 application to an 8.1 application?
A: For instructions, see "Upgrading Database and Metadata Files from 7.0 to 8.1" in "Upgrading to WebLogic Portal 8.1" in the WebLogic Portal 8.1 Upgrade Guide at http://download.oracle.com/docs/cd/E13218_01/wlp/docs81/upgrade/chapter3.html.
Q: How do I upgrade WebLogic Portal 7.0 SP2 skins to Look and Feels?
A: WebLogic Portal 7.0 SP2 skins and user interface (UI) components can be re-hosted to Look and Feels and the appropriate components in the 8.1 release. To find out how the presentation framework is used, and how you can create skins, layouts, and look and feels for use in the new framework, see "Creating Look & Feels" in the WebLogic Workshop Help at the following URL:
http://download.oracle.com/docs/cd/E13226_01/workshop/docs81/doc/en/portal/buildportals/ifLF.html
Q: How has anonymous user tracking changed?
A: When you create anonymous user profiles with WebLogic Portal 7.0 SP2, the data about an unregistered user that is collected during a single session is persisted only if the user registers. With WebLogic Portal 8.1, you can track unregistered users over multiple visits, which means you can present personalized content to anonymous users.
Q. How do I upgrade WebLogic Integration applications to 8.1 SP5 from an earlier release of 8.1?
A. Before you start upgrading your WebLogic Integration applications to SP5, make sure you have already upgraded them to SP4.
