Java 在cPanel godaddy.com中未找到servlet错误
我已经在godaddy.com上注册了一个域名，比如www.example.com，并且有一个cPanel帐户。我已经部署了我的项目的.war文件，并将其上传到cPanel中，然后将其解压缩。当我访问我的域（www.example.com）时，初始index.jsp文件将被加载，所有javascript文件都能正常工作。但当它必须从javascript文件中发出AJAX请求时，它会说“404错误”。找不到Servlet！'。我的servlet和类文件位于Public_html/WEB-INF/classes/com/Fb/FaceBookServlet.java文件夹下，这是我的WEB.xml文件Java 在cPanel godaddy.com中未找到servlet错误,java,web-services,servlets,web,web-hosting,Java,Web Services,Servlets,Web,Web Hosting,我已经在godaddy.com上注册了一个域名，比如www.example.com，并且有一个cPanel帐户。我已经部署了我的项目的.war文件，并将其上传到cPanel中，然后将其解压缩。当我访问我的域（www.example.com）时，初始index.jsp文件将被加载，所有javascript文件都能正常工作。但当它必须从javascript文件中发出AJAX请求时，它会说“404错误”。找不到Servlet！'。我的servlet和类文件位于Public_html/WEB-INF/c

您可能需要使用其他标记，以吸引更多的观众，请在此处阅读FaceBookServlet.java和index.jsp代码“Public\u html/WEB-INF/classes/com/Fb/FaceBookServlet.java文件夹”。在classes目录下有Java源文件吗？这不是编译的吗？我怀疑是打包问题，而不是与源代码直接相关的任何问题…FaceBookServlet.java和FaceBookServlet.class文件都位于同一文件夹下。。。。那么，如果我删除包并将文件放在Public_html/WEB-INF/classes文件夹下，是否可以？您可能需要使用其他标记，以吸引更多的观众。请在此处输入您的FaceBookServlet.java和index.jsp代码。'Public_html/WEB-INF/classes/com/Fb/FaceBookServlet.java文件夹'。在classes目录下有Java源文件吗？这不是编译的吗？我怀疑是打包问题，而不是与源代码直接相关的任何问题…FaceBookServlet.java和FaceBookServlet.class文件都位于同一文件夹下。。。。那么，如果我删除包并将文件放在Public_html/WEB-INF/classes文件夹下是否可以？？？
