WSO2 MessageBroker:充当发布者时引发javax.naming.NoInitialContextException错误

我必须访问WSO2主题才能从我的终端发布数据。所以我创建了一个客户机，但在运行时遇到以下异常

这种情况下的问题是什么。我只添加了javax.jms.jar文件作为外部jar。我必须添加WSO2特定罐吗

看起来类路径中可能没有客户端JAR。您可以在/client libHi@RaviU中找到客户机jar。我的java程序中是否需要MB客户端JAR？我只有jms还不够吗？NVM让它开始工作了。是的，问题是我没有所需的库：）看起来类路径中可能没有客户机JAR。您可以在/client libHi@RaviU中找到客户机jar。我的java程序中是否需要MB客户端JAR？我只有jms还不够吗？NVM让它开始工作了。是的，问题是我没有必要的库：）
