Resources such as JavaScript and CSS files can be compressed before being sent to the browser, improving network efficiencies and application load time in certain case. If you are not using Apache with mod_deflate or nginx in front of your web application, you may need to implement resources compression yourself….
Wait! don’t start writing your own filter to compress files like CSS, html, txt, javascript it is way more difficult than you think to properly handle http response headers and do proper handling of mime type and caching. In one sentence don’t start reinventing the wheel: use ehcache for example.
Ehcache is an open source, standards-based cache used to boost performance, offload the database and simplify scalability. Ehcache is robust, proven and full-featured and this has made it the most widely-used Java-based cache. It can scale from in-process with one or more nodes through to a mixed in-process/out-of-process configuration with terabyte-sized caches. For applications needing a coherent distributed cache, Ehcache uses the open source Terracotta Sever Array.

Here is 3 different way to control the lifetime a local Tomcat 7 container using Apache Maven. A typical scenario would be to start a servlet container prior to running integration tests (Selenium, SAHI or using any other framework you can think of )
With the following examples, you will be able to start an instance of Tomcat 7 running your web application in the pre-integration-test phase and stop the instance in the post-integration-test phase. You can also decide to use an embedded container like Jetty instead.

I will show you in an Apache Maven configuration file how to copy files to server each time the package phase is executed.
Solution with Ant SCP task
This snippet of code is a ready to use code that make use of Apache Ant task scp, Just put this snippet of code in your Maven module where the assembly is executed or anywhere else to push all tar.gz files to a server just run a maven mvn package, you can add as many ant task and push to many server the same file during the reactor build.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
<execution>
<id>server-copy</id>
<goals>
<goal>run</goal>
</goals>
<phase>package</phase>
<configuration>
<target>
<echo message="Push to server/home/"/>
<scp trust="yes"
todir="user:password@server:/home/">
<fileset dir="${basedir}/target">
<include name="**/*.tar.gz"/>
</fileset>
</scp>
</target>
</configuration>
</execution>
</executions>

</plugin>
Solution with maven-deploy-plugin
The maven-deploy-plugin allows you to configure the deploy phase to deploy to a server using scp. There is a page in the documentation that describes how it can be done.
Deploy maven artifact using Maven Wagon SCP
Another alternative would be to use Maven Wagon SCP like described in this post for example

First a big thanks to Packt Publishing for having sent me this book to review! I did enjoy going through this book, while I did not learn a lot of new stuff (I am using Apache Maven daily since 2006!), I found it to be concise and would recommend it anytime to any of my colleagues. But let’s go through my review of this cookbook of over 50 recipes towards optimal Java Software Engineering with Maven 3:
Apache Maven 3 Cookbook is a clear, precise, well-written book that gives readers clear recipes for the release process using Apache Maven 3. The authors give a step-by-step account of expectations and hurdles for software development.
The first few chapters quickly bring you to the point to be comfortable using Maven on straightforward projects, and the later chapters provide even more recipes examples on subjects like running a Repository Manager, Writing Plugins, and details on various techniques. The book also covers numerous real world software delivery issues such as multi-module projects, web/enterprise projects, dependency management, automatic testing and documentation.
To sum up key points from this 224 pages book in a few bullets:
The author Srirangan go into detail in describing each of these themes.
I recommend you this book if
if you want to be able to deliver your software to any target environment, using continuous delivery processes, chances are high that Apache Maven is the right tool for this job, and this book should be part of your technical library, beside also of course the free online book of Sonatype Maven: The Complete Reference
