我正在尝试让 aSmack 在我的项目中工作。在 Eclipse 中创建了一个标准项目,将 jars(smack.jar、smackx-debug.jar、smackx-jingle.jar、smackx.jar)添加到 libs 文件夹。开始使用 XMPP 类,但我不确定是否应该做其他事情来正确设置项目(稍后),因为它不起作用。当我运行应用程序时出现此错误Could not find class 'java.beans.PropertyDescriptor', referenced from method org.jivesoftware.smack.util.PacketParserUtils.parseWithIntrospection
,当我尝试发送消息时出现此错误java.lang.IllegalStateException: Not connected to server.
并且at org.jivesoftware.smack.XMPPConnection.sendPacket(XMPPConnection.java:445)
这是我正在使用的代码

任何人都在您的 XMPP 客户端中遇到过这个问题。是 jar 文件中的问题还是我必须更改代码中的任何内容...
