我想写一些文件,像这样:

FileWriter fw = new FileWriter("somefile.txt", true);

它由单个进程启动时正常工作.像这样:

java -jar XXXXXXX.jar

但是当由另一个进程调用它时,将抛出IOException.例:

java.io.FileNotFoundException: 'somefile.txt' (No such file or directory)
    at java.io.FileOutputStream.openAppend(Native Method)                      
    at java.io.FileOutputStream.<init>(FileOutputStream.java:192)              
    at java.io.FileOutputStream.<init>(FileOutputStream.java:116)             
    at java.io.FileWriter.<init>(FileWriter.java:61)
