运行环境报错,该如何解决??
程序开发环境: TOMCAT 5.0 + JDK1.5
移植到运行环境:Resin 3.0 +JDK 1.5
运行时报错:
class file has wrong version 49.0, should be 48.0
Please remove or make sure it appears in the correct subdirectory of the
classpath.
当换成 JDK 1.4 编译后 放到 运行环境:Resin 3.0 +JDK 1.5
运行时报错 Unsupported major.minor version 49.0
请问该如何解决?谢谢
