Java正在tomcat bin文件夹中创建文件

Question

I have written a java program in which I am creating a file.

BufferedWriter writer = 
    new BufferedWriter(
        new OutputStreamWriter(
            new FileOutputStream("myfile.txt"))

It is creating the file in the current folder (my project folder). Till here everything is perfect. Now I have designed a servlet and call this class. The file is now getting created in the tomcat bin folder. Do I need to make any changes to classpath or server.xml or context.xml in tomcat?

Answer 1

CAUSE:

Your program is creating a new file in the "current working directory".

Since it's a servlet running inside of Tomcat, the "current directory" happens to be Tomcat's "bin" directory.

SUGGESTIONS:

• If possible, use a fully qualified path ( "/tmp/myfile.text" )

• You can also write your file relative to getServletContext() :

• You can use a relative path, and parameterize either that path in a properties file ( WEB-INF\\myprog.properties ) or JVM parameter ( -D filepath=/my/file/path ).
