2 Upgrading WebLogic Server 4.5 and 5.1 to Version 7.0
2-14 BEA WebLogic Server 7.0 Upgrade Guide
See weblogic.xml Deployment Descriptor Elements in Assembling and Configuring
Web Applications.
JavaServer Pages (JSPs) and Servlets
This section contains information specific to JSPs and servlets that may be pertinent to
your applications.
Some changes will be necessary in code (both Java and HTML) where the code
refers to URLs that may be different when servlets and JSPs are deployed in a
Web Application other than the default Web Application. See Administration
and Configuration in Programming WebLogic Server HTTP Servlets for more
information. If relative URLs are used and all components are contained in the
same Web Application, these changes are not necessary.
Only serializable objects may be stored in a session if your application is
intended to be distributable.
You must convert your weblogic.properties file to XML attributes in
web.xml and\or weblogic.xml. For additional information on this process, see
the conversion section of the Console Help.
Access control by an ACL has been replaced with security-constraint based
access control in the web application deployment descriptor.
Server-side-includes are not supported. You must use JSP to achieve this
functionality.
WebLogic Server 7.0 is fully compliant with the Servlet 2.3 specification.
Update your web.xml file so that it uses the following new classes:
weblogic.servlet.proxy.HttpClusterServlet
instead of
weblogic.servlet.internal.HttpClusterServlet
and
weblogic.servlet.proxy.HttpProxyServlet
instead of
weblogic.t3.srvr.HttpProxyServlet
