Additional Porting and Deployment Considerations
BEA WebLogic Server 7.0 Upgrade Guide 2-29
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 has been replaced by a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.
