我无法写入文件
我使用 tomcat5.32 + cpanel 。
我的代码是：
<%
String path = application.getRealPath("");
path +="/as.txt" ;
FileOutputStream fos = new FileOutputStream(path);
fos.write("this is test ?".getBytes());
fos.flush();
fos.close();
%>
当请求时出现此错误：
java.io.FileNotFoundException: /home/domainname/public_html/ROOT/as.txt (Permission denied)
java.io.FileOutputStream.open(Native Method)
java.io.FileOutputStream.<init>(FileOutputStream.java:179)
java.io.FileOutputStream.<init>(FileOutputStream.java:70)
org.apache.jsp.newjsp2_jsp._jspService(newjsp2_jsp.java:61)
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:98)
javax.servlet.http.HttpServlet.service(HttpServlet.java:729)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:369)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:308)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:259)
javax.servlet.http.HttpServlet.service(HttpServlet.java:729)
权限是0644，但我的程序无法写入自己的文件。
请帮我

该错误非常明显，您没有对该文件具有写入权限。
您的许可，
0644仅向拥有该文件的用户添加读/写权限。任何一个让您的 Tomcat 用户成为所有者，或将该用户包含到文件组中并应用权限
0664。The error is quite clear, you don't have write permissions to the file.
Your permission,
0644addsRead/Writerights only to the user owning the file. Eithermake your Tomcat user the owner, or include the user to the files group and apply the permission
0664.1) 确保尝试写入此文件的“用户”实际上具有权限。写入磁盘的 JVM 可能不会使用与启动 JVM 的用户相同的权限。
2) 在尝试写入文件之前，确保该目录路径的所有步骤均实际存在。
1) Ensure that the 'user' that is attempting to write to this file actually has permissions. JVM writing to the disk may not use the same Permissions as the User who launched the JVM.
2) Ensure all steps of that dir path actually exist prior to attempting to write to a file.
