线程“main”中的异常java.lang.UnsupportedClassVersionError：org/apache/axis2/transport/SimpleAxis2Server（不支持的major.minor版本49.0

Question

我在 64 位 Solaris 9 操作系统上部署 Axis2 v1.5.3 时遇到问题，我想知道应该怎么做才能使用 JDK 6 成功运行此 Axis2 实例？

在这个操作系统中安装了多个Java JDK版本，但我已经设置了环境。 var 指向 1.6 二进制文件。

突然我意识到我总是可以打开 setenv.sh 文件，然后手动对其进行硬编码以获得更安全的选择，

export AXIS2_HOME="/opt/local/sys/axis2-1.5.3"
export JAVA_HOME="/usr/java1.6/bin/java"
export AXIS2_CLASSPATH="$AXIS2_CLASSPATH"

这是历史日志：

尝试在 ~/.profile 和 ~/.bashrc 中为要运行此命令的用户添加此位。

export JAVA_HOME=/usr/java1.6
export PATH=$PATH:$JAVA_HOME/bin 

重新启动控制台会话并确保在运行 java -showversion 命令时获得 java 6 版本
