连接DB2驱动的问题

Mubai

我的服务器用TOMCAT 4.1,现在JSP页面中连接DB2数据库.

我先把DB2的驱动db2java.zip解开成COM目录,然后用jar cvf db2java.jar COM打包,然后把db2java.jar放到TOMCAT的common/lib目录下.

可是JSP中:
Class.forName("COM.ibm.db2.jdbc.app.DB2Driver";
这句老出问题:
java.lang.NoClassDefFoundError
        at java.lang.Class.forName0(Native Method)
        at java.lang.Class.forName(Class.java:141)
        at org.apache.jsp.db_jsp._jspService(db_jsp.java:46)
        at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:92)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:809)

        at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:187)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:809)
为什么老LOAD不上啊?请高人指点.急死人了.

直接把db2java.zip改成db2java.jar
