BEA WebLogic Server 7.0 Upgrade Guide

The following procedure ports the simple Hello World Servlet that was provided with 
WebLogic 5.1 Server to WebLogic Server 7.0.

1. In WebLogic Server 7.0, create the correct directory structure, as described in 

 in Programming WebLogic Server HTTP 

Servlets. This involves creating a root application directory, such as 

C:\hello

, as 

well as a 

C:\hello\WEB-INF

 directory and a 

C:\hello\WEB-INF\classes

 

directory. Place the 

HelloWorld.Servlet.java

 file inside the 

C:\hello\WEB-INF\classes

 directory. 

2. Create a 

web.xml

 file for this servlet. If you have converted your 

weblogic.properties

 file, a 

web.xml

 file has already been created for you. If 

you registered HelloWorldServlet in your 

weblogic.properties

 file before 

you converted it, the servlet will be properly configured in your new 

web.xml

 

file. An XML file can be created with any text editor. The following is an 
example of a basic 

web.xml

 file that could be used with the HelloWorldServlet.

<!DOCTYPE web-app (View Source for full doctype...)> 
- <web-app> 
- <servlet> 
<servlet-name>HelloWorldServlet</servlet-name> 
<servlet-class>examples.servlets.HelloWorldServlet</servlet-cla
ss> 
</servlet> 
- <servlet-mapping> 
<servlet-name>HelloWorldServlet</servlet-name> 
<url-pattern>/hello/*</url-pattern> 
</servlet-mapping> 
</web-app>

For more information on 

web.xml

 files, see 

 in Assembling and Configuring Web Applications. A 

weblogic.xml

 file is not necessary with such a simple, stand-alone servlet as 

HelloWorld.
