sqlldrコマンドを実行するJSFアクションBeanにメソッドを書きましたが、 「プロセス」でjava.io.IOException：プログラム "sqlldr"を実行できません：CreateProcessエラー= 2、指定されたファイルが見つかりません
しかし、私がスタンドアロンのJavaプログラムとして試したときに、同じコードがうまく動作し、テーブルにデータをロードします。
注：OracleとJavaのパスも....
に設定されている... :(
以下を助ける必要が私のコードです：どのアクション豆で
方法ボタンのクリック時に呼び出されます
public String executeControlFile() {
try {
Runtime rt = Runtime.getRuntime();
Process pr = rt.exec("sqlldr userid=system/root control=d:\\emp\\emp.ctl log=d:\\emp\\empNew2.log");
BufferedReader input = new BufferedReader(new InputStreamReader(pr.getInputStream()));
String line=null;
while((line=input.readLine()) != null) {
System.out.println(line);
}
int exitVal = pr.waitFor();
System.out.println("Exited with error code "+exitVal);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
