現在、JAXP、SAX、DOM、StAX、XPath、およびXSLTを学習しています。 StAXの動作を確認するためにテストしていたのですが、エラーが発生しました。FileReaderが同じフォルダ内のXMLファイルを見つけることができません
Exception in thread "main" java.io.FileNotFoundException: test.xml (The system cannot find the file specified)
at java.io.FileInputStream.open0(Native Method)
at java.io.FileInputStream.open(FileInputStream.java:195)
at java.io.FileInputStream.<init>(FileInputStream.java:138)
at java.io.FileInputStream.<init>(FileInputStream.java:93)
at java.io.FileReader.<init>(FileReader.java:58)
at xmltest.XMLTest.main(XMLTest.java:16)
それは古典的な誤りだ、と私はそれが何を意味するか知っている、問題がある、「のtest.xml」と「XMLTest.java」は、同じフォルダ内にあるので、私はなぜそれが現れてされるかわかりません/パッケージ。ここで
は、以下のコードです:
XMLTest.java -
package xmltest;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.Reader;
import javax.xml.stream.XMLInputFactory;
import javax.xml.stream.XMLStreamException;
import javax.xml.stream.XMLStreamReader;
public class XMLTest {
public static void main(String[] args) throws FileNotFoundException, XMLStreamException {
XMLInputFactory xmlif = XMLInputFactory.newFactory();
Reader reader = new FileReader("test.xml");
XMLStreamReader xmlsr = xmlif.createXMLStreamReader(reader);
while (xmlsr.hasNext()) {
switch (xmlsr.next()) {
case XMLStreamReader.START_ELEMENT:
System.out.println("START_ELEMENT");
System.out.println(" Qname = " + xmlsr.getName());
break;
case XMLStreamReader.END_ELEMENT:
System.out.println("END_ELEMENT");
System.out.println(" Qname = " + xmlsr.getName());
}
}
}
}

ありがとうございます。 :)
EDIT 私は、ファイルへの絶対パスを入れると、それは完璧に動作しますが、私はハードコードにこれをしたくない...
を使用して、あなたのファイルの絶対パスを提供することができますか? – bradimus
XMLTest.javaとtest.xmlは同じディレクトリにある可能性があります... XMLTest.classとは? –
私はNetbeansを使用して、私が前にやったすべてのようにプログラムを実行します... 過去にFileReading、ファイル管理などを多用していましたが、なぜこれが今起こっているのか分かりません:( –
