在eclipse下运行runjet来启动项目，报错误:
ERROR - log                        - Failed startup of context org.mortbay.jetty.webapp.WebAppContext@19fe451{/,WebContent}
org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.app.doaImpl.SequenceSqlMapDao] for bean with name 'sequenceDao' defined in class path resource [applicationContext.xml]; nested exception is java.lang.ClassNotFoundException: com.app.doaImpl.SequenceSqlMapDao
at org.springframework.beans.factory.support.AbstractBeanFactory.resolveBeanClass(AbstractBeanFactory.java:1138)
找不到com.app.doaImpl.SequenceSqlMapDao，但该类确实存在，以前采用struts+spring，也是采用同样的配置文件，没报错。

还有个问题，自己编译运行wicket-example，报
ERROR - log                        - failed WicketExamplesMenuApplication
org.apache.wicket.WicketRuntimeException: Application class org.apache.wicket.examples.portlet.menu.WicketExamplesMenuApplication must be a subclass of WebApplication
at org.apache.wicket.protocol.http.ContextParamWebApplicationFactory.createApplication(ContextParamWebApplicationFactory.java:76)
at org.apache.wicket.protocol.http.ContextParamWebApplicationFactory.createApplication(ContextParamWebApplicationFactory.java:49)
。。

第一个问题找到原因了，拼写错误。
第二个问题不知怎么解决了。

居然用runjetty插件就是报第二个错误，采用eclipse server方式，用tomcat作为server，正常运行。
