B Upgrading the Pet Store Application and the Examples Server

„An example of the above-listed config.xml file used for WebLogic Server 7.0 which includes explanations for how to change this script to upgrade the Examples Server toWebLogic Server 7.0.

Note: To upgrade the Pet Store application to WebLogic Server 7.0, it is not necessary to update the DTDs in the weblogic.xml and web.xml files. See weblogic-ejb-jar.xml Document Type Definitions in Programming WebLogic Enterprise JavaBeans for information on WebLogic Server 7.0 DTDs

Fix JSP Parsing Errors

Minor errors that were parsable in earlier versions of WebLogic Server cause errors in WebLogic Server 8.1 because JDK 1.4 does not accept them. The errors corrected in this section are property settings for which the method and setter properties do not agree.

Correcting the errors requires making changes to these source files:

ListTag.java

CartListTag.java

MyListTag.java

ProductItemListTag.java

ProductListTag.java

SearchListTag.java

All of these files are located in the

WL_HOME\samples\petStore\src\petstore\src\com\sun\j2ee\blueprints

\petstore\taglib\list directory (where WL_HOME is the WebLogic Server installation directory)

Use these steps to make the replacement in ListTag.java:

1. In a command console, navigate to

WL_HOME\samples\petStore\src\petstore\src\com\sun\j2ee\blueprin ts\petstore\taglib\list. For example:

C:\> cd

WL_HOME\samples\petStore\src\petstore\src\com\sun\j2ee\blueprin ts\petstore\taglib\list

2. Open ListTag.java in a text editor. For example:

WL_HOME\samples\petStore\src\petstore\src\com\sun\j2ee\blueprin ts\petstore\taglib\list>notepad ListTag.java.
