the executable war with embedded jetty

The project is created by Eclipse Indigo
Project name : jettyExam
Environment requirment : Maven 3.0.4

The main function is defined in "jettyExam/src/main/java/Runner.java". It is responsible to create a Jetty Server.
The servlet app is in "jettyExam/src/main/java/hello/app/HelloWorldServlet.java".
The map which is to communicate url and servlet app is defined in "jettyExam/src/main/webapp/WEB-INF/web.xml".

The example dosen't support JSP, because some jar file is not included.
The main effort is to maintain "jettyExam/pom.xml":
In order to source code is compiled successfully, the dependency is key point.

            <dependency>  
              <groupId>org.eclipse.jetty</groupId>  
              <artifactId>jetty-server</artifactId>  
              <version>${jettyVersion}</version>  
              <scope>provided</scope>  
            </dependency>  
            <dependency>  
              <groupId>org.eclipse.jetty</groupId>  
              <artifactId>jetty-webapp</artifactId>  
              <version>${jettyVersion}</version>  
              <scope>provided</scope>  
            </dependency>

Meanwhile, "provided" can avoid these jar files to be packaged into war file.

If JSP need be supported, the following dependency should be contained:

           <dependency>
             <groupId>org.eclipse.jetty.orbit</groupId>
             <artifactId>org.apache.jasper.glassfish</artifactId>
             <version>2.2.2.v201112011158</version>
             <scope>provided</scope>
           </dependency>
           <dependency>
             <groupId>org.eclipse.jetty.orbit</groupId>
             <artifactId>javax.el</artifactId>
             <version>2.2.0.v201108011116</version>
             <scope>provided</scope>
           </dependency>

The war file would increase 800KB size, if JSP dependency is contained.
So it suggest to comment the JSP dependency.

In addition, some plugins are essential.
maven-war-plugin will define "main" class in MANIFEST.MF.
maven-antrun-plugin will move the "main" class to the root path of war file.
maven-dependency-plugin will decompress the dependency jar files.

After perform "run"->"run as"->"maven install" in Eclipse, the jettyExam.war can be found in the target fold.
now we can run java -jar -Dport=10080 jettyExam.war and check the result via browsing http://localhost:10080/ and http://localhost:10080/helloworld
