看了一下Java API，应该是初始化的时候，哪儿有问题，但是又查不出来。

错误提示全文如下：
java.lang.ExceptionInInitializerError
all.HibUtil.(HibUtil.java:27)
com.mytest.struts.action.AdduserAction.execute(AdduserAction.java:49)
org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:419)
org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:224)
org.apache.struts.action.ActionServlet.process(ActionServlet.java:1194)
org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414)
javax.servlet.http.HttpServlet.service(HttpServlet.java:743)
javax.servlet.http.HttpServlet.service(HttpServlet.java:856)


源代码如下：
