2Upgrading WebLogic Server 4.5 and 5.1 to Version 7.0
2-28 BEA WebLogic Server 7.0 Upgrade Guide
FileServlet
In WebLogic Server 6.1 Service Pack 2 and later, the behavior of FileServlet, which is
the default servlet for a Web Application, has changed. FileServlet now includes the
SERVLET_PATH when determining the source filename. This means that it is
possible to explicitly only serve files from specific directories by mapping the
FileServlet to /dir/* etc.
See Setting Up a Default Servlet.
Internationalization (I18N)
Several internationalization and localization changes have been made in this version:
Changes to the log file format affect the way that messages are localized. The
new message format also has additions to the first line: begin marker, machine
name, server name, thread id, user id, tran id, and message id.
A new internationalized logging API enables users to log messages in the server
and clients.
Clients log to their own logfiles, which are in the same format as the server
logfiles, with the exception of the servername and threadid fields.
LogServicesDef is deprecated. Instead, use the internationalized API or
weblogic.logging.NonCatalogLogger (when internationalization is not
required).
For details on internationalization in this version, see the Internationalization Guide.
Java Transaction API (JTA)
JTA has changed as follows:
WebLogic Server 7.0 supports the JTA 1.0.1 specification. Updated JTA
documentation is provided in Programming WebLogic JTA.
