hi,
i am new to j2ee. i want to install j2ee in linux. i have downloaded
java_ee_sdk-5_05-linux-nojdk.bin. should i download any other
packages? Can anyone guide me through the installation.

I highly recommend you use whatever package manager comes with your
distribution to install the JDK, both SE and EE. This is the path of
least resistance and will cause the least amount of headaches.

For example I use Kubuntu, and Adept is my package manager. There are
multiple JDKs available for download, including Sun's. Being a package,
the package manager handles all of the installation tasks.
