I tried it again today.
The link works now but when trying to buy an Unix version of the docs, it sends you a useless Windows executable.
ComponentSource has added a "Unix Edition" to all JBoss documentation in the JBoss store.
If you select the Unix Edition when purchasing JBoss documentation, you will not be required to download a Windows executable file as part of the download. You will be able to directly download the documentation .ZIP file.
