我有一个使用两个jars axis.jar和axisCognosClient.jar连接到cognos环境的应用程序
Cognos将其版本从cognos 10.1.1升级到了cognos 10.2，我从Cognos 10.2 SDK中提取了一个新的jar文件，并将其包含在我的项目中，一切都成功完成，但是在运行时出现了以下异常。

知道为什么我们会得到这种例外。
最佳答案
检查您的Java版本以了解Cognos安装和您的应用程序使用的Java版本。
对于Cognos 10.1：IBM Cognos BI随附的当前版本是JRE 1.5.0。
对于Cognos 10.2：IBM Cognos BI随附的当前版本是JRE 6.0。
