如何从 java web 应用程序创建 http 可见文件？
如何在 web/myFiles 文件夹中的 java Web 应用程序中创建通过 http 协议可见的文件？
这可能吗？
对于以下代码：
String realPath = getServletContext().getRealPath("/");
System.out.println(realPath);
try {
BufferedWriter out = new BufferedWriter(new FileWriter( realPath + "\\myFiles\\test.txt"));
out.write("aString\nthis is a\nttest");
out.close();
} catch (IOException e) {
System.out.println("Exception " + e);
}
我不断收到错误：
Exception java.io.FileNotFoundException: C:\Documents and Settings\Andrei\My Documents\NetBeansProjects\SemanticCashUpV1.0\build\web\myFiles\test.txt (The system cannot find the path specified)
How can I create files visible by http protocol from java web application in web/myFiles folder ?
Is this even possible ?
for the following code :
String realPath = getServletContext().getRealPath("/");
System.out.println(realPath);
try {
BufferedWriter out = new BufferedWriter(new FileWriter( realPath + "\\myFiles\\test.txt"));
out.write("aString\nthis is a\nttest");
out.close();
} catch (IOException e) {
System.out.println("Exception " + e);
}
i keep getting the error :
Exception java.io.FileNotFoundException: C:\Documents and Settings\Andrei\My Documents\NetBeansProjects\SemanticCashUpV1.0\build\web\myFiles\test.txt (The system cannot find the path specified)
