simple custom generator

[Yingfang Tian <yi...@gmail.com>]

Hi, I am new to Cocoon. I try to write a cusom generator and follow
the guide described in
http://cocoon.apache.org/2.1/tutorial/tutorial-generator.html#Simple+Example.
When I compile the HelloWorldGenerator.java, the following errors
showed up.Could you give me any suggestion? Thank you very much.

(HelloWorldGenerator.java is copied from the above website, I put
cocoon-2.0.4.jar and xml-apis.jar in the c:\cocopractice\lib.
My environment is : j2sdk1.4.2_06;  jakarta-tomcat-4.1.31;  cocoon-2.0.4)

C:\CoCoPractice\test>javac -classpath
c:\cocopractice\lib\cocoon-2.0.4.jar;c:\cocopractice\lib\xml-apis.jar
HelloWorldGenerator.java

1) you need the avalon / excalibur libraries in order to compile. Have a 
look in WEB-INF/lib of your cocoon installation for these.
2) Just FYI, development of the cocoon 2.0.X branch stopped about 2 
years ago. Current active branch is 2.1.X
