macOS Java and FTP help!

[jtalerico]

Hey guys I am trying to get my Java code to connect via FTP to my site, and upload a file. Not sure how this will work. This is what i have so far!

            String wsave = JOptionPane.showInputDialog(null, "File Saved! Would you like to upload it?");
            if(wsave.equals("yes") || wsave.equals("y")) {
                URL site = new URL("ftp://MYUSER:*******@ftp://69.68.181.132/Sites/txt/; type=i");
                URLConnection conn = site.openConnection();
                File output = new File("ftp://69.68.181.132/Sites/txt/");
                Writer saveSite = new BufferedWriter(new FileWriter(output+input));
                saveSite.write(text);
                save.close();
                conn = null;
            }
        }

And i am catching the exception, so i am always getting File could not be written... Is there a way to "upload" or BufferedWriter the file on the server? Thanks!

Opening a connection via the site.openConnection does not have any effect on other classes. So you cannot do that then expect that creating a File with the same address will work. It won't. You will need to do something directly with the URLConnection. What I don't know: I haven't read the documentation.

These are the errors i am getting now...


2006-02-04 16:13:23.048 java[4201] CFLog (0): CFMessagePort: bootstrap_register(): failed 1103 (0x44f), port = 0x11f03, name = 'java.ServiceProvider'
See /usr/include/servers/bootstrap_defs.h for the error codes.
2006-02-04 16:13:23.051 java[4201] CFLog (99): CFMessagePortCreateLocal(): failed to name Mach port (java.ServiceProvider)

Here is the new code...

            if(wsave.equals("yes") || wsave.equals("y")) {
                System.out.println("end");
                URL site = new URL("ftp://xxxxx:xxxxxx@ftp://192.168.0.22/Sites/txt/; type=i");
                URLConnection conn = site.openConnection();
                File output = new File(input);
                BufferedOutputStream os = new BufferedOutputStream(conn.getOutputStream());
                System.out.println("end");
                FileOutputStream in = new FileOutputStream(input);
                os.close();

hey joe -- you forgot to X out your username and password in your second example.

 

[jtalerico]

Fixed thanks. just changed it

Damn what a day... And thoughts on what is wrong?

 

[zimv20]

thoughts on what is wrong?

nah, i haven't done java in 6 years and even then i never messed with connecting to an ftp server. however, a quick google search for java and ftp found this promising page.

I'd suggest using Apache Commons Net

Then give a looksy at this source for an example..

 

[jtalerico]

Is there somewhere that will tell me how to use this? Install it...

Well, first put the commons-net-1.4.1.jar file somewhere in the classpath. Then look at the Javadoc or the source link I provided...

 

[jtalerico]

i have put the .jar file into my classpath and i still cannot get the thing to compile with this line....

import org.apache.commons.net.*;

import org.apache.commons.net.*;

Then it's not in the classpath. How are you trying to compile?

Also, did you extract the .jar file from the .zip file you downloaded from Apache?

 

[jtalerico]

yes, i extracted the jar file from the tar.gz...

I put the file into the /System/Lib.../Framework/JavaVM..../1.4.2/Classes/

That should be the classpath...

BTW Thanks for the help!

 

[jeremy.king]

I would NOT suggest putting jar files there, instead learn to use the -classpath flag of the javac command. If you are using an IDE, they usually have a similar way to setup the classpath. For example, in Eclipse you can add .jar files as Libraries to a project's build path which for compilation purposes will include the .jar when you try to compile.

So again, how are you trying to compile this class(es)?

 

[jtalerico]

Okay, i got all that worked out!! Thanks guys! Once again you guys are the greatest!!

But one more question!!!

Say i have a password field, and they are entering it in a JOptionPane.. I would like it to be **** instead of the plane text.. How do I do so? Thanks again guys!
