We will take a quick walk through the installation of the Apache
Geronimo Java application server. Geronimo not only runs servlets and JSP,
but it is also, as we shall see in later chapters, a J2EE EJB container, so the
installation part of this chapter is important for using the examples and
technologies covered in the remaining chapters.
Geronimo is a complete application server. It provides a full, production-
ready, J2EE environment. It is the stated goal of the Geronimo project to pass
the Sun J2EE certification tests. Such certification will, in all probability,
quickly make Geronimo one of the most widely used J2EE application servers.
A great deal of Geronimo information can be found on the Geronimo
Web site.

NOTE
As of this writing, the project was just nearing the certification process. Only the
milestone releases were available for downloading. By the time you read this,
however, a fully certified version will likely be production-ready. There may be
slight differences in the download and installation procedures. Be sure to follow
the instructions from the Web site and any readme files for the most up-to-date
information.
First off, you must choose what form of the product to download. The
choice is really between a binary and source distribution. Within that choice,
you can choose between two compression methods,
zip
or
tar
/
gzip
. While the
first is typical for Windows distributions and the second for Linux, you can
choose either, as Linux has utilities for decompressing both. More importantly,
the binaries are Java JAR files so they are not tied to a particular operating sys-
tem. We will download and install a binary. Just click on the
tar.gz
filename
and save the file.
If you haven't read the previous sections because you were going to skip
JBoss and just use Geronimo, please go back and read Section 20.3. It deals
with administration and privileges for setting up your installation, and you'll
want to know that for this chapter's installation discussion, too.
18. As of this writing, there was still a legal hurdle to overcome, since Sun requires derivative
works to be branded and compatible, whereas the Apache license places no such requirements
on its derivative works. This may be resolved by the time you are reading this.
