Just a few notes:
1. WSDL2Java and Java2WSDL are in org.apache.axis.wsdl package and should be in axis.jar that comes with your Axis2 download (at least with 1.5). You can find numerous examples of invoking these classes directly or via
Ant.
2. This page (as you probably know) lists the tools:
http://ws.apache.org/axis2/tools/index.html
3. All of the tools are compatible with Axis2 1.4 but not 1.5. You can try to use them with 1.5, but you will run into issues sooner or later
4. Yes, most of the links are broken, unfortunately. So instead of clicking on
ftp://apache.cs.utah.edu/apache.org/ws/axis2/tools/1_4/axis2-eclipse-codegen-wizard-1.4.zip, you can try going into it one directory at a time. So first go here:
ftp://apache.cs.utah.edu/apache.org/ws/axis2/ - this way I am guessing you will have a good chance of success

And you will also notice that the directory paths have changed, e.g. its not 1_4 but 1_4_1. But its there.
