weblogic 对银联网关支付的问题

总是找不到类 Ensure that the annotations are valid. The error is com.unionpay.acp.demo.consume.Form_6_2_FrontConsume2
stacktrace
Caused By: java.lang.ClassNotFoundException: com.unionpay.acp.demo.consume.Form_6_2_FrontConsume2

在tomcat 一切正常 部署到weblogic 瞄的怎么也不行
已经设置了weblogic.xml

xmlns="http://www.bea.com/ns/weblogic/90"
xmlns:j2ee="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-web-app.xsd">

true

求解决方法,是否是jar包冲突呢?
用的是 spring+hibernate
