FTP Connection Through JAVA

I am writing a java code to transfer a file from local machine to a server on another machine.
While uploading i am encountering with an exception which is showing as
java.net.ConnectException: Connection refused: connect
The file is getting transferred sucessfully if i am transferring it through command prompt instead of java code.
Please help me out.

Hi Kali,
I have worked on similar issues sending you the code.. hope it should work. I had written a TelnetInterface class where I did all operation inside the constructor.

     private boolean isConnected ;

     public TelnetInterface(HttpServletRequest request) {
               HttpSession session = request.getSession();
               PropertyReader propReader = (PropertyReader)session.getAttribute("propReader");

Problem with socket connection through Java Embedding...

We are trying to create a simple socket connection to a socket server through BPEL PM using the Java Embedding component.
BPEL Process : Client makes an asynchronous request. Passes an input variable. The input variable is sent to the Server Program through a socket connection through the Java embedding component.
Server: We are running a simple Socket Server program from command prompt.
The code below works fine as long as we do not try to receive a response from the server (Commented Code).
If we uncomment the code and try to receive a response, it refuses to create an instance for the BPEL Process. And sometimes restarts the BPEL Server.
Client Code:
String msg="NONE";
try{
org.w3c.dom.Element input = (org.w3c.dom.Element) getVariableData("inputVariable","payload","/client:clientProcessRequest/client:input");
msg = input.getNodeValue();
Socket clientsoc=new Socket("ServerIP",1000);
PrintWriter out1=new PrintWriter(clientsoc.getOutputStream());
out1.write(msg);
out1.flush();
BufferedReader cin1=new BufferedReader(new InputStreamReader(clientsoc.getInputStream()));
msg=cin1.readLine();
setVariableData("outputVariable","payload","/client:result",new String(msg));
clientsoc.close();
catch(UnknownHostException e)
System.err.println("Don't know about host: dev.");
System.exit(1);
catch (IOException e)
System.err.println("Couldn't get I/O for "+ "the connection to: dev.");
System.exit(1);
}

How do I get SQL Agent to perform an FTP connection through a SSIS package?

I have created a number of SSIS packages that I am running through SQL Agent in various jobs. I have set up a Credential / Proxy for the job steps and for the most part everything runs no problem. The issue I have is with the step where I make
a connection to a FTP server and download files. In BIDS the step works fine but in SQL Agent the step times out. I presume that it has to do with the account that it is being run under but that is what I thought the Credential / Proxy was supposed
to handle (as it does for all the other steps). I am running on SQL Server 2008 R2. I have created a test job that has only one step which is to connect to the FTP server and download some text files. I have tried utilizing package configuration
files and have tried various ProtectionLevels to no avail.
Anyone have any thoughts or direction for me to take? Will continue to research and will post if I resolve this.
Thanks, Andrew

On the dev environment the ProtectionLevel is set to EncryptSensitiveWithUserKey and that is what I tried first on the prod server. Subsequently I also tried utilizing a package config file (with ProtectionLevel then of DontSaveSensitive) and have
also tried working with the ServerStorage.
For deployment I copied the relevant dtsx files to a solution on the prod server. I verified that the packages all had tested connections in the Connection Manager. I have run all the packages in the BIDS on the prod server and they all worked.
I have created a test package from scratch on the prod server to test the ftp connection. This test package runs from BIDS fine. I have set the SQL Agent file to access through the file system (no luck) and have saved the package to the SSIS Packages
and had the job step access from there (no luck either).

Background scheduling of FTP Connection through R/3

Hello Friends,
I have done FTP connection by using Z-pgm which uses function FTP_CONNECT. This is working fine in Foreground mode.
But in background scheduling of the z-pgm, i am getting the <b>error as 'RFC to program SAPFTP failed'.</b>
I checked RFC destination SAPFTP in SM59. There Activation type is 'Start on Front End Work Station'. I tested the connection also. Its alright.
How to do FTP processing in Background?
Cheers,
Seema

Hello,
you could try to use RFC destination 'SAPFTPA' - it's ftp on the application server. Since SAPFTP is 'Start on Front End Work Station' and in background there is no front end work station, it can't work.

Well The issue was somewhere else due to it reading too much of data. It ran but my program is very slow (approx 2-3 hrs).
I am worried about the speed...
is it because of the large amount of data.. 23,355,459 records..?? or there could be some issue in programming probably memory leak etc..??
-> reads db
-> for each record set
-> perform different operation/ writes to file

Hello sir,
I have create 1 java class file which connects to SAP DB through RFC connection.
I have put sapjco3.dll,librfc32.dll,sapjcorfc.dll in to the folder windows\system32.
Its working fine on windowsXP, but not working on Windows Vista and windows server 2003.
its giving error as

its side-by-side configuration is incorrect.
please tell me what configuration i have to do for vista and server 2003.

Hi guys,
please pay attention to the given infos on the JCo download site. It says:
Note: Starting with JCo 2.1.4 and JCo 2.0.11, JCo requires the Visual Studio .NET C/C++ runtime libraries on Windows platforms.
Starting with JCo 3.0.0, it requires the Visual Studio 2005 C/C++ runtime libraries. See SAP note [684106|https://service.sap.com/sap/support/notes/684106] for details on how to install them.
Installing the VC redistributable packages from Microsoft will solve this issue.

FTP connections through Finder not reporting correct file size

Hi,
I have a NAS that running as an FTP server. When I connect to it through Finder it reports the incorrect file size of 2.7GB (the real file size is 61GB)
Its an DMG image file so it obviously fails when I try to image a new IMAC.
FTP through windows reports the correct file size so rules out any problem on the NAS.
Any ideas anybody?
Many thanks.

Mainframe connection through java

Hi,
Is it possible to connect to a mainframe and retrieve the results from it i.e., the data stored are in the form of cards(record types).Is it possible to connect to such set up using JDBC connectivity as we do for the normal RDBMS connection..
Kindly help me in this regards
Wiht thanks in advance
subra

Why on earth should a "mainframe" (you even didn't tell us which OS) be such a magic zone that even Java can't enter it?
How do other programming languages manage to connnect to a DBMS on a mainframe?
How has for example Oracle succeeded to be used on mainframes?
I think you should ask your DBMS' vendor at first.
"Mainframe" is a collective name for certain hardware structures only.

Getting result from a telnet command through Java

Hi,
I've been using a set of classes found here: http://javatelnet.org/
to do telnet through Java in a non-interactive mode.
However I've got a problem when retrieving the result of a command sent to the remote host: the classes read the stream until the prompt is encountered; my problem is I must execute commands on several remote hosts, and the prompt is not necessarily the same on all hosts.
Is there a simple means to establish a telnet connection through Java and retrieve the result of the commands?
Any help would be appreciated.

Thanks again, this is a very good article
I see it is still the same strategy to get the result of a command : wait 'til the prompt is sent. Maybe there is just no other way to get it .
But as I don't know the prompt on the different hosts I have to query, this won't do it.
The article gave me an idea though : I only need to count the files in a directory on the remote host; until now I was trying to send the 'ls | wc -l' command by Telnet.
Maybe I can simply do it by FTP (retrieve the list of files, and then count the lines with JAVA).

finally {

ftpClient.disconnect(true);
catch (Exception e) {

So I know the proxy settings are correct.
The java version I used to compile and run my apps is 1.6.0_06 Does anyone can help figure out what is wrong when I use the Apache commons net FTP client?
Thank you

Is the old AirPort Extreme base station (AEBS)
configured so that the option to distribute IP
addresses is DISABLED? If so, configure the new AEBS
to act as a bridge.
Are you suggesting I use a set-up with TWO AEBSs? Set up a bridge (not sure how) and then use the old AEBS to connect to the DSL modem and broadcast to the new Extreme which will then be the router to the other computers on the network?
Do you have any port mapping or default host enabled
on the old AEBS?
I do not understand, not do I see these options in the Base Station utitlity; perhaps they are in the FTP options--but that, I'm sorry to say, is not obvious to my inspection.
Duane, can you give me a few more basic instructions? Thanks
