在应用程序中获取java库错误

我有一个部署在WebSphere上的web应用程序，它使用一个java库生成excel格式的文件，但是我在WebSphere中遇到了以下错误，但是它可以与TOMCAT服务器一起正常工作

有什么问题吗

错误是：-

错误500:java.lang.LinkageError:LinkageError在定义类时：

无法定义jxl.format.CellFormat，原因是：（jxl/format/CellFormat）偏移量为6的主版本错误这通常是由于在类加载器层次结构中的多个位置定义了一个类造成的。其他潜在原因包括针对具有不兼容的方法签名的较旧或较新版本的类进行编译。转储当前上下文类加载器层次结构：==>表示定义类加载器==>[0]com.ibm.ws.classloader。CompoundClassLoader@50c450c4本地类路径：C:\Program
