问题描述:

elsewhere eg.[1] it is explained that when you install the java source in

ubuntu, it is put here: /usr/lib/jvm/java-6-sun-1.6.0.20/src.zip

The problem is that it does not contain the javax.activation package

and thus not classes like: javax.activation.DataSource

Why isn't it there?

Must I download the source manually to get that?

[1] Where to find Java JDK Source Code?

网友答案:

The package is javax.activation, not java.activation - and typically, source code for javax... packages isn't included.

网友答案:

The various components of javax use different licenses, so this could be the reason. I've taken the liberty to ask your platform of choice's maintainers here.

I will update this answer as soon as I get an answer.
