Additional Porting and Deployment Considerations

„Based on the inclusion of support for JTA, the JTS JDBC driver (with properties in weblogic.jts.* and URL jdbc:weblogic:jts:..) has been replaced by a JTA JDBC/XA driver. Existing properties are available for backward compatibility, but you should change the class name and properties to reflect the JTS to JTA name change.

Java Database Connectivity (JDBC)

The following changes have been made to JDBC:

„The WebLogic T3 API was deprecated in WebLogic Server 6.1; use the RMI JDBC driver in its place. This also applies to users porting from WebLogic Server 4.5.x.

„The weblogic.jdbc20.* packages are being replaced with weblogic.jdbc.* packages. All WebLogic JDBC drivers are now compliant with JDBC 2.0.

„If you have a current connection and are using a preparedStatement, and the stored procedure gets dropped in the DBMS, use a new name to create the stored procedure. If you recreate the stored procedure with the same name, the preparedStatement will not know how to access the newly created stored procedure—it is essentially a different object with the same name.

JSP

Error Handling

The behavior of the JSP include directive has changed between WebLogic Server 5.1 and the current version. In versions through WebLogic Server 5.1, the JSP include directive logged a Warning-level message if it included a non-existent page. In WebLogic Server 6.0 and later, it reports 500 Internal Server Error in that case.You can avert the error by placing an empty file at the referenced location.
