[code]import embedded.EmbeddedTomcatLauncher;

public class MyTomcatLauncher extends EmbeddedTomcatLauncher {
public static void main(String[] args) {
//开始运行嵌入式Tomcat，狠简单，就new一下当前类然后startTomcat()就行
new MyTomcatLauncher().startTomcat();
}

//这里返回你要加载的项目的绝对地Ö返ÄString数组
@Override
protected String[] getContextsAbsolutePath() {
return new String[] {
"/home/hongliang/workspace/scaffold/webapp"
};
}

//这里返回你上面写的项目要映射后的路径，跟上面的数组一一对应
@Override
protected String[] getContextsMappingPath() {
return new String[] {"/scaffold"};
}

//这里返回你embedded tomcat的地址
@Override
protected String getTomcatPath() {
return "/home/hongliang/libraries/tomcat/apache-tomcat-5.5.15-embed";
