Accessing local file from server side using Java Application

[ersachinjain]

Hi

I want to write a code that will access the local file from the server side using Java Application. I have my java code running as a server and I want to access the file located in the local system which is connected with the server where my java code is running.

Thanks

Sachin

What kind of client/server application do you have?
Is it a web application or are you serving a Java application via webstart e.t.c?
Why did you post this in the databases forum?

Hi r035198x

I know I did that by mistake putting this post under database. But I was told that it is related with ODBC so i thought may be this is the best tittle. I have a java program running on my company's server. It is not a client-server model but just a simple java program that has to run 24x7 coz it extracts data from the website. Now i have access a file located in the local system which is connected with this server.

Thanks

How is the client computer connected to the server? Are the two computers on the same network and are able to communicate with each other say, via ssh, ftp?

[ersachinjain]

The two computers are on same network I guess. I can let you know that once i talk to the system admin. But can I coonect to that system by using the IP Address of the system and access those files.

Thanks

Copying a file over the network then? The code has been written lots of times.
Google will point to an assortment.

The thing is that I have to establish a connection with that machine and for that I have written:

url = "jdbc:odbc:10.1.0.207";

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

conn = DriverManager.getConnection (url, "administrator", "meri");

10.1.0.207 being the IP address of that machine.

but it gives me null pointer exception.

I really appreciate your help. Thanks

Why are you using JDBC at all?
You are not trying to get data from the database, you are just trying to copy a file over the network, right?

[ersachinjain]

Yes you are right.

I have made slight changes to my code:

url2 = new URL("http","10.1.0.120","C:/password.txt");

URLC = url2.openConnection();
filein = URLC.getInputStream();

This is what i am using. But it is giving me an exception filenotfound even though the file is there.

Just copy the file as an output stream using a Socket/BufferedOutputStream pair.
Just google "Copying a file over the network Java" and you should get countless examples.
