很明显我已经加入了jasper这个jar包，有哪位大哥玩OSGI的还请问，这个是怎么回事？是因为缺少javax.servlet.jsp这个jar包的引入吗？但是书中的例子中并没有要引入此包，而且就算我在配置文件中引入，又会报别的包，在引入也是有问题，太让人费解了。
--------------------编程问答-------------------- Tomcat 5版本太低了，版本改大点，
或改用Jetty --------------------编程问答-------------------- 请问我这个用的tomcat是spring-dm 1.1.3包中自带的，如何改大 ，我用spring-dm2包是不是就可以了呢？但是官网上不知为何 下载不了2的。 --------------------编程问答-------------------- 改大，具体版本号不确定的时候，可以将版本号去掉，如
org.apache.jasper, org.osgichina.demo.timeservice, --------------------编程问答-------------------- 遇到同样问题！
补充：Java , Java EE
