I need to transfer one XML file to other FTP server on same network.

Please suggest me best method to do it.

I was thinking about sockets but in that case i need to put one programme on server machine also, right ?

If right then I dont want to do this.

Please suggest some better way.

Thanks and Regards,

using this command :

javac -classpath "C:\Program Files\Apache Software Foundation\apache-tomcat-6.0.13\lib\servlet-api.jar":classes:. -d classes src\com\

Errors I am getting like this:

e.g. :

src\com\ package javax.servlet does not exist
import javax.servlet.*;

As far as I know everything is correct in path. I have installed new tomcat and servlet-api.jar is there in lib.

Please suggest a solution.

sorry for late reply.

after including quotes i was getting 5 errors:

One of them:
F:\project1>javac -classpath "C:/Program Files/Apache Software Foundation/Tomcat
4.1/common/lib/servlet-api.jar" -d classes src/
src\ package javax.servlet does not exist
import javax.servlet.*;


Then I changed sevlet-api.jar to servlet.jar(this one is ther ein lib directory) and now it is working

Thanks to all you people for replying.
