How to read a text file from a Restful web service

IamtheWalrus

Hi all,

I am writing a Jersey Restful service to be deployed on Tomcat via a war file.

The service needs to read data in 3 text files. The text files need to exist on the file system or read from the classpath. I have tried to read the data from the file system and classpath but neither are working. I would be happy with either way - it doesn't matter.

If it was to use the following code,can someone tell me where to place the text file specified so that the code picks up the file?

BufferedReader br = new BufferedReader(new InputStreamReader
(this.getClass().getClassLoader().getResourceAsStream("myfile.txt")));

I am getting a null pointer exception.

If I was to read the file from the file system, use the following code, where do I place the files in my Jar?

FileInputStream fs = new FileInputStream("myFile.txt");
DataInputStream is = new DataInputStream(fs);
BufferedReader br = new BufferedReader(new InputStreamReader(is));

I am getting a FileNotFound exception.

Any suggestions are welcome.

First block of code assumes that file.txt is in the WEB-INF/classes folder of your war or it will throw a NPE

Second block of code will look for the file in the current working directory of the java process. You would need to give it an absolute path for it to work if you wanted to take that approach in a war.

Thanks. Yes you are right. I used my build.xml to copy my text file into the classes folder and it worked.
