I have tried this multiple times, so there has to be something wrong here. Basically, I have downloaded and compiled the source for Jboss AS 4.0.4GA. Now, I am trying to install JBoss Portal on top of it. I am still trying out RC1 due to some issues with forums I have been told in the later versions. Well, when I download the source, the entire "thirdparty" directory is missing, unlike in the documentation. Well, when I try "build datasource" I get an error that the target isn't defined. If I do a "build deploy" from the build directory, it downloads the thirdparty and other directories, but the "build datasource" from the core directory still doesn't work. Why is there such an ambiguous documentation? Is there a nice helpful HOWTO/tutorial book out there? Thanks for the help!
