You are trying to run your jar file using an older version of the JVM. 您正在尝试使用旧版本的JVM运行jar文件。 You compiled under JDK7 and are trying to run under JDK6 or earlier. 您在JDK7下进行编译，并试图在JDK6或更早版本下运行。 You need to set the target Java version in Netbeans to the version matching your client's environment. 您需要将Netbeans中的目标Java版本设置为与客户端环境匹配的版本。
