2 Upgrading WebLogic Server 4.5 and 5.1 to Version 7.0

Web Components

The following tips are for users porting to WebLogic Server 7.0 who used Web components in their previous version of WebLogic Server:

„All Web components in WebLogic Server now use Web Applications as the mechanism for defining how WebLogic Server serves up JSPs, servlets, and static HTML pages. In a new installation of WebLogic Server, the server will configure a default Web Application. Customers upgrading to WebLogic Server 7.0 should not need to perform any registrations because this default Web Application closely approximates the document root, the JSPServlet, and servlet registrations performed using the weblogic.properties file contained in earlier versions.

„Convert your existing weblogic.properties file to XML files using the Administration Console. See the Console Help for more details.

„SSI is no longer supported.

„URL ACLs are deprecated. Use Servlet 2.3 features instead.

„Some information has moved from web.xml to weblogic.xml. This reorganization allows a third-party Web application based strictly on Servlet 2.3 to be deployed without modifications to its J2EE standard deployment descriptor (web.xml). WebLogic Server 5.1 style settings made in the web.xml file using <context-param>elements are supported for backward compatibility, but you should adopt the new way of deploying. The following sets of parameters previously defined in web.xml are now defined in weblogic.xml:

JSP Parameters (keepgenerated, precompile compileCommand, verbose, packagePrefix, pageCheckSeconds, encoding)

HTTP sessionParameters (CookieDomain, CookieComment,

CookieMaxAgeSecs, CookieName, CookiePath, CookiesEnabled,

InvalidationIntervalSecs, PersistentStoreDir,

PersistentStorePool, PersistentStoreType, SwapIntervalSecs,

IDLength, CacheSize, TimeoutSecs, JDBConnectionTimeoutSecs,

URLRewritingEnabled)
