Jboss 3.2.7 seems like a patch. Should install 3.2.6 before apply it.
jboss-3.2.7 certainly is not a patch.
The package (jboss-3.2.7_jdk13.zip) I downloaded is only 8MB.
This is what the snippet of the readme coming with the package
The jboss-3.2.7 release for the J2EE? 1.3 codebase is a bug fix and minor feature enhancement release. A jboss-3.2.x getting started guide that is based on contents of the J2EE? 1.3 tutorial can be found on the JBoss web site documentation section, 3.2 Getting Started Guide.
