最近项目往weblogic上迁移，JApplet不能正常使用，控制台报错：

异常：java.lang.ClassFormatError: Incompatible magic value 1013478509 in class file com/futuresoftware/oa/workflow/define/DesignerApplet

解决方法：
    
     项目部署目录下同web.xml同目录，增加weblogicx.xml文件 配置
<session-descriptor>
<cookie-http-only>false</cookie-http-only>
</session-descriptor>

     贴上weblogic.xml
   

<!DOCTYPE weblogic-web-app PUBLIC "-//BEA Systems, Inc.//DTD Web Application 8.1//EN" "weblogic810-web-jar.dtd"> <weblogic-web-app> <session-descriptor> <cookie-http-only>false</cookie-http-only> </jsp-descriptor> </weblogic-web-app>

重启服务，搞定！
