never just about development From the advent of enterprise Java there has been a strictly defined holistic role concept Component providers, assemblers, system administrators, and server providers have clear and distinct responsibilities, but these have been rarely upheld in the real world Because of politics and organizational structures, often the developer assumes the re‐ sponsibility of all these roles, with the possible exception of system administration and operations The developer’s main goal is development, and the well-intentioned role separation collapses quickly m o c 777 k o o b e w w In the “real world,” a dedicated operations department takes the results of the develop‐ ment cycle and attempts to install, run, and just keep it alive Such an artificially sepa‐ rated model works, but is far away from being optimal Sometimes it gets even worse, and signing off documents becomes more important than software quality w If you are only interested in quick hacks, you will hate Java EE, application servers, and probably this book altogether Packaging, deployment, monitoring, and management sounds like bloat and is bloat, if you are only focusing on development However the “DevOps” movement also considers operations and development as a single unit Who needs beautiful code that cannot be properly installed in a predefined environment? DevOps is nothing groundbreaking; rather, it’s a “back to the roots” movement This book is not just compatible with the “DevOps” ideals; it pragmatically shows how to build a Java EE application from scratch and also patches holes in the Java EE spec Automation of project and archive creation, pragmatic integration of Maven builds into the process, and testing on all levels are deeply explained with concrete code Rather than focusing on best-case scenarios, this book shows you how to test the inconvenient, including examples with SMTP servers or Message Driven Beans Although the tools, libraries, and frameworks introduced in this book were initiated by Red Hat employees, this book will be equally valuable for you if you are not using JBoss vii www.it-ebooks.info WWW.EBOOK777.COM Free ebooks ==> www.ebook777.com or WildFly at all In fact, I used Arquillian, ShrinkWrap, and Forge to test applications on GlassFish and TomEE at the same time Also, in my workshops I use Arquillian to test plug-ins, extensions, and sophisticated dependency injection without deploying mocks to a production archive It was fun to read this book on the flight to JavaOne 2013 in San Francisco; I learned a lot I wish you happy reading—enjoy the lightweight Java EE development lifecycle! —Adam Bien http://adam-bien.com m o c 777 k o o b e w w w viii | Foreword www.it-ebooks.info WWW.EBOOK777.COM Free ebooks ==> www.ebook777.com The default DNS record will be in the format http://appName-domainId.rhcloud.com It’s likely that this isn’t really the name we desire for public consumption, so let’s add our own custom DNS name This is a two-step process: Create a DNS entry with your domain registrar or DNS Management interface to point to http://appName-domainId.rhcloud.com In our case, we’ll opt for a sub‐ domain, which amounts to a CNAME record Consult your domain authority for the specifics of this step, but generally you might be presented with a screen that looks similar to Figure 11-14 Figure 11-14 Add CNAME Add an “alias” in your OpenShift application’s configuration You can this via the web interface shown in Figure 11-15 Figure 11-15 Add alias m o c 777 k o o b e w w w Alternatively, you can acquire the OpenShift client-side command-line tools These rely on a Ruby installation of 1.8.7 or greater on your system, and are obtained by installing a Ruby gem: $> sudo gem install rhc Once the gem is installed, you can add the domain record to OpenShift using the com‐ mand rhc alias add appName alias -l username For instance: $> $ rhc alias add geekseek geekseek.continuousdev.org -l admin@continuousdev.org Password: ***************** Alias 'geekseek.continuousdev.org' has been added Assuming the CNAME is properly set up with your domain registrar, the record has percolated through the network’s DNS tree (which may or may not take some time), and the alias is set up correctly, your application should now be available directly at the provided alias In our case, this is http://geekseek.continuousdev.org/ 226 | Chapter 11: Assembly and Deployment www.it-ebooks.info WWW.EBOOK777.COM Free ebooks ==> www.ebook777.com Removing the Default OpenShift Application Now let’s clear the way for our real application First we’ll clone the OpenShift applica‐ tion repository into our local workspace The Git URL for your application is displayed on the application’s status screen on your OpenShift account The git clone command will look a little like this: $> git clone ssh://(somehash))@geekseek-continuousdev rhcloud.com/~/git/geekseek.git/ Cloning into 'geekseek' The authenticity of host 'geekseek-continuousdev.rhcloud.com (72.44.62.62)' can't be established RSA key fingerprint is cf:ee:77:cb:0e:fc:02:d7:72:7e:ae:80:c0:90:88:a7 Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'geekseek-continuousdev.rhcloud.com,72.44.62.62' (RSA) to the list of known hosts remote: Counting objects: 39, done remote: Compressing objects: 100% (31/31), done remote: Total 39 (delta 1), reused (delta 0) Receiving objects: 100% (39/39), 19.98 KiB, done Resolving deltas: 100% (1/1), done Now we have a full copy of the OpenShift application’s repository on our local disk Because we don’t need the default landing page shown in Figure 11-13, we can safely remove it We can this easily by cd-ing into our repository directory, removing the files in question with git rm, committing the changes, and then pushing the commit to the remote OpenShift repository: m o c 777 k o o b e w w $> cd geekseek geekseek $> git rm -rf pom.xml src/ rm 'pom.xml' rm 'src/main/java/.gitkeep' rm 'src/main/resources/.gitkeep' rm 'src/main/webapp/WEB-INF/web.xml' rm 'src/main/webapp/images/jbosscorp_logo.png' rm 'src/main/webapp/index.html' rm 'src/main/webapp/snoop.jsp' geekseek $> git commit -m 'Remove OpenShift default application structure' geekseek $> git push origin master w When the git push command concludes and the remote build is complete, reloading our application in the web browser should now yield us a blank page, because we’ve deleted the only content in the OpenShift repo We’ll replace that with fresh content from our CI builds Pushing from the CI Build Job to OpenShift The final piece of the automated deployment puzzle lies in deploying artifacts built from our CI server into our runtime environment In our case, this amounts to configuring Pushing to Staging and Production www.it-ebooks.info WWW.EBOOK777.COM | 227 Free ebooks ==> www.ebook777.com the CloudBees Jenkins instance to perform some Git operations against our OpenShift repository We’ll need to allow access for CloudBees Jenkins to interact with the OpenShift repos‐ itory On the Configure screen for our CI job is a section named CloudBees DEV@Cloud Authorization, which contains our public key (see Figure 11-16) Copy this to your OS’s clipboard Figure 11-16 CloudBees SSH public key Then log in to your OpenShift Management Console and select Settings; there will be a dialog to manage the public keys allowed access to our repository (see Figure 11-17) Add the CloudBees Jenkins key by pasting it here m o c 777 k o o b e w w w Figure 11-17 OpenShift public keys Switching back to our Jenkins job configuration screen, toward the bottom is a section where we can add “post-build” steps (see Figure 11-18) Let’s create a shell-based action that will be set to execute only upon successful build 228 | Chapter 11: Assembly and Deployment www.it-ebooks.info WWW.EBOOK777.COM Free ebooks ==> www.ebook777.com Figure 11-18 CloudBees post-build steps The following script will handle the task for us: if [ -d geekseek ]; then cd geekseek if [ -f deployments/ROOT.war ]; then rm -rf deployments/ROOT.war fi git pull origin master else git clone ssh://51abd6c84382ec5c160002e2@geekseek-continuousdev.rhcloud.com/ ~/git/geekseek.git/ cd geekseek fi m o c 777 k o o b e w w cp $WORKSPACE/code/application/application/target/*.war deployments/ROOT.war touch deployments/ROOT.WAR.dodeploy git add -Av COMMIT_MESSAGE='Updated application from ' COMMIT_MESSAGE=$COMMIT_MESSAGE$BUILD_URL git commit -m "$COMMIT_MESSAGE" git push origin master w Let’s see what’s going on here First we have some bash logic to either clone the remote OpenShift repository if this node hasn’t already, or update the existing copy Then we copy the final deployable web application We’ll WAR into the deployments directory of the repository, renaming it to ROOT.war so that this acts as our application servicing requests from the web root Also, we’ll add or update an empty ROOT.war.dodeploy file to let OpenShift know that we want this application deployed when it’s discovered (full documentation on this feature is available on the OpenShift site) Finally, we add our changes to be staged for commit, perform the commit, and then push the changes to our remote OpenShift repository As we’ve seen before, OpenShift will dutifully exercise the remote operations to redeploy our application and make it available for our use Pushing to Staging and Production www.it-ebooks.info WWW.EBOOK777.COM | 229 Free ebooks ==> www.ebook777.com Using the OpenShift client command-line tools, we can tail the server logs for the ap‐ plication to monitor status: $> rhc tail {openshift_appname} -l {openshift_username} If we look closely, we’ll see that the application has deployed, and is ready for use! 2013/06/04 05:38:52,413 INFO

WWW.EBOOK777.COM Free ebooks ==> www.ebook777.com CHAPTER 12 Epilogue Now this is not the end It is not even the beginning of the end But it is, perhaps, the end of the beginning — Winston Churchill Enterprise Java is, as technologies go, not a highly opinionated landscape; it does not prescribe only one way of accomplishing a task Although Java EE provides a suite of APIs, we’ve seen in our GeekSeek example that it may be appropriate to look outside the platform and integrate with external frameworks This freedom carries with it a burden of choice: developers new and seasoned alike may find that bringing together a working application at all layers may carry complexity m o c 777 k o o b e w w w We’ve set out to show one cohesive application, but this is not a book of best practices We’ve taken one approach of many, and it fit our requirements What we intend to underscore is the importance the role of testing takes in respon‐ sible development The applications we deploy into production are composed of much more than what we write on our own; we need to be sure that all components are working in concert Additionally, it’s helpful to isolate business logic where we can, and further ensure that everything is connected properly when integrated The Arquillian project in particular has been a wonderful means for us to explore the bounds of how simple we can make testing of even the most complex use cases, and its community has been instrumental in pushing the limits of testability in a landscape that has historically been cumbersome to manipulate We hope that the techniques outlined here, on the companion source repository, and running proof in production on http://geekseek.continuousdev.org are beneficial to your own path in building reliable applications in

primarily responsible for development of the company’s EJB 3.x implementation He was an early adopter of Java EE technologies and is an active contributor in the tech community Aslak Knutsen, the project lead of Arquillian, is a senior software engineer at JBoss, by Red Hat He’s involved in projects such as Arquillian, ShrinkWrap, Weld, and Seam and is one of the founders of the JBoss Testing initiative, as well as a speaker at major industry conferences including Devoxx, JavaOne, Jazoon, JFokus, and Geecon Colophon The animal on the cover of Continuous Enterprise Development in Java is a Violet Turaco (Musophaga violacea), also known as a Plantain Eater, a large bird inhabiting West Africa in tropical savannas, wetlands, woodlands, and forests Its plumage is a glossy violet color except for its thick orange bill, yellow forehead, and crimson crown The main flight feathers on the wings are also crimson in color However, despite these bright colors, the birds are often quite indistinguishable in the dense canopy of their forest home m o c 777 Like all turacos, the Violet Turaco is an important disperser of seeds When flying in search of fruit, rounded wings and a long, widespread tail give the turaco great agility when maneuvering through the dense treetops Its flight is characterized by irregular, flapping wing beats interspersed with gliding To cross an open space, they fly single file k o o b e w w w Their diet consists of fruit, and they are quite partial to figs, but they will also eat leaves, buds, flowers, insects, snails, and slugs For savanna species, the widespread destruction of gallery forest and riverine woodlands is a big threat However, because of its wide distribution and great numbers, the Violet Turaco is not in imminent peril For the same reason, it’s not in danger from trapping for the pet trade, though local people hunt them for their ostentatious red feathers The cover image is from Wood’s Animate Creation The cover fonts are URW Typewriter and Guardian Sans The text font is Adobe Minion Pro; the heading font is Adobe Myriad Condensed; and the code font is Dalton Maag’s Ubuntu Mono www.it-ebooks.info WWW.EBOOK777.COM
