java.lang.UnsupportedClassVersionError：偏移量爲6的主要版本不佳

我在我的tomcat的webapps文件夾中部署了WAR file。當我開始我的tomcat，像下面java.lang.UnsupportedClassVersionError：偏移量爲6的主要版本不佳

C:\apache-tomcat-6.0.35\bin>startup.bat 
Using CATALINA_BASE: "C:\apache-tomcat-6.0.35" 
Using CATALINA_HOME: "C:\apache-tomcat-6.0.35" 
Using CATALINA_TMPDIR: "C:\apache-tomcat-6.0.35\temp" 
Using JRE_HOME:  "C:\Program Files (x86)\IBM\RationalSDLC\Common\Java5.0\jre" 
Using CLASSPATH:  "C:\apache-tomcat-6.0.35\bin\bootstrap.jar"

我得到這個下面exception-

這是我的JAVA版本 -

C:\apache-tomcat-6.0.35\bin>java -version 
java version "1.6.0_26" 
Java(TM) SE Runtime Environment (build 1.6.0_26-b03) 
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

誰能提供任何建議爲什麼會發生？
