why does wso2 carbon 4.1.0 contains 2 copies of axiom and axis in the source tree?

Question

I have checked out wso2carbon 4.1.0 source:

svn checkout http://svn.wso2.org/repos/wso2/carbon/kernel/branches/4.1.0 wso2carbon

in the dependencies folder, there is:

axiom\1.2.11-wso2v4
axis\1.6.1-wso2v9

and

orbit\axiom\1.2.11.wso2v4
orbit\axis2\1.6.1.wso2v9

I can see that the first two end with -wso2v4/9 and the other two end with .wso2v4/9

What is the purpose of these different projects with similar names?

Answer 1

in the dependencies folder, there is:

axiom\1.2.11-wso2v4
axis\1.6.1-wso2v9

It contains axis/axiom source files, which are dependencies.

orbit\axiom\1.2.11.wso2v4
orbit\axis2\1.6.1.wso2v9

Here we make osgi bundles out of those dependencies. If you check those orbit/..folders only pom file is present.
