解压出jetty.jar中的org/mortbay/jetty/webapp/webdefault.xml文件，将这一选项由true改为false，另存到src/main/resources目录，或者其它自选目录。

<init-param> <param-name>useFileMappedBuffer</param-name> <param-value>true</param-value> <!-- change to false --> </init-param>

在pom.xml中加入对这个文件的指向：

<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>maven-jetty-plugin</artifactId>
<configuration>
<webDefaultXml>src/main/resources/webdefault.xml</webDefaultXml>
</configuration>
</plugin>

本人已经验证通过。

问题描述，点这里。

mvn archetype:create -DgroupId=com.mycompany.app -DartifactId=my-webapp -DarchetypeArtifactId=maven-archetype-webapp

创建要注意遵循MAVEN的目录结构，尤其要注意源文件要放在main/java下：



2. POM文件的配置

这里要特别注意对resource一节的配置，因为我的SPRING以及WEB相关的XML是放在WEB-INF目录，为了在unit test的时候也能用，加入了对这些配置文件的引用。相当于加了一个classpath。

这里还有个插曲：不知为何MAVEN2里没有JTA的包，自动下载时会有提示教你如何手工通过命令加入，非常简单。

JETTY的plugin是为后面用它来调试做准备。

DWR也是目前WEB开发一个热选。

另外，为使用JAVA5代来编译，加入了maven-compiler-plugin一节。
