我正在教程中培训wso2中代理的创建：https://docs.wso2.com/display/ESB490/Sending+a+Simple+Message+Through+the+ESB 并且在第2遍的“构建和部署SimpleStockQuoteService”中遇到了一些问题，当我尝试运行wso2server.bat时，我收到了以下消息：
"Starting Sample Axis2 Server ..."
Using AXIS2_HOME: C:\Oxaguia spk\Trabalhos\Coach IT\Piramidal\Servers\wso2ei-6.1.1\samples\axis2Server
Using JAVA_HOME: C:\Program Files\Java\jdk1.8.0_121
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0
Server could not start due to class loading issue java.lang.NoSuchMethodException: samples.util.SampleAxis2Server.startServer([Ljava.lang.String;)
我在互联网上看到，这是因为我的jdk版本，我尝试了1.7.0_45和1.6.0_45。在这种情况下，我有这样的信息：
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/tools/ant/launch/Launcher : Unsupported major.minor version 52.0

AXIS2_HOME也是这样创建的：'C：\ Oxaguia spk \ Trabalhos \ Coach IT \ Piramidal \ Servers \ wso2ei-6.1.1 \ samples \ axis2Server'
我真的不知道发生了什么。如果有人能帮助我，我会非常感激。
ps：在尝试了584的教程后，为了更改axis2server.bat，在git hub中，我收到了这条消息：
