Accessing an object from a different server

Hi,
I am making a program that will access an object from a different server.
I have a program that when I run calls a jsp page running on Server A which in turn should request an object A from Server B.
I am relatively new to Java and jsp. What would my best course of action be.
Thanks in advance,
Brian

Or RMI?OK, sounds good, I will look up some RMi on the site.
Thanks, will prob have more questions for you later.

Trying to use FTP to get data from a different server

Hi Friends,
    I have to use FTP to get data from a different server and upload it on SAP server. Now my problem is when I m trying to do ftp through command line it brings the file but with no data.

Sending an object from client to server always on button press

What I need is to send an object from client to server but I need to make server wait until another object is sent. What I have is the JFrame where you put the wanted name and surname, then you create a User object with these details and on button press you send this object to the server. I just can't hold the connection because when I send the first object, server doesn't wait for another button click and throws EOFexception. Creating the while loop isn't helpfull as well because it keeps sending the same object again and again. The code is here
public class ClientFrame extends JFrame {
    private JButton btnSend;
    private JTextField txfName;
    private JTextField txfSurname;
    public ClientFrame() {
        this.setTitle(".. ");
        Container con = this.getContentPane();
        con.setLayout(new BorderLayout());
        txfName = new JTextField("name");
        txfSurname = new JTextField("surname");
        btnSend = new JButton(new AbstractAction() {
            @Override
            public void actionPerformed(ActionEvent e) {
                SSLSocketFactory f =
                        (SSLSocketFactory) SSLSocketFactory.getDefault();
                try {

Current code fails because it's sending still the same entity again(using while loop)No it's not. You are creating a new User object every time around the loop.
which makes the system freezeWhich means that you are executing network code in the event thread. Don't do that, use a separate thread. At the moment you're doing all that sending inside the constructor for ClientFrame which is an even worse idea: you can never get out of there to the rest of your client program. This is a program design problem, not a networking problem.
and doesn't allow me to set new parameters of the new entityI do not understand.
I need to find a way to keep Server running even when the client doesn't send any data and wait until the client doesnt press the send button again to read a new object.That's exactly what happens. readObject() blocks until data is received.

Accessing java objects from within javascript

Passing a object from browser to server

How can i pass a java object from browser to server, can anybody help me in knowing this?
Rajesh.

You might need to clarify this. What exactly do you need to do? You can't pass anything from a browser except HTML, other than by attachment. If you have a Java object, then I assume that you are using JSP or something that supports Java, in which case you are already using server-side semantics.
If however, you mean Javascript, that's a whole other problem, as it is client side only.
Perhaps if you clarify what you are trying to do someone can give you a good answer.

Is it possible to access a database on a different server?

Hi Folks
Forgive me if this has been asked already. We are in the
process of moving one of our sites to a new server. It will reside
there alone. I have several Access databases that are shared
between two different websites. Now these sites will reside on two
different servers. Is there any way to access one Access database
that resides on one server from another server? The good part is
the second sever will be using the data for read-only outputs.
Thanks in advance for any help you can priocdie.
John

MS Access is not really intended for networking in this
manner, and I would imagine that you would have problems with
locking contention at the very least with two CF servers vying for
access. Also, another major problem with attempting to set up an
Access DSN where the ColdFusion server is on a different machine
from the Access database is file permission. Normally, ColdFusion
is setup on its server under an administrator account, so if you
attempt to connect to an Access database on another server over a
mapped network drive, the admin account on your CF server usually
does not have the appropriate privileges on the machine hosting the
Access database. This usually requires you to install CF under a
user account that has privileges on both machines. (There have been
tech notes on this subject in the past.)
Bottom line, not a good idea at all. I would seriously
consider migrating to anything but Access for these and many other
reasons, the least of which is that Access is usually not suitable
for anything but a development or prototype environment.

Accessing Java objects from C++ client

I have a number of Java CORBA server objects that I have deployed to an 8.1.7 database.
I can invoke these objects from a Java client with no problem, but I also need to access them from a C++ client.
I have used idl2cpp from VisiBroker for C++ (version 4.5) to generate the client stubs, and I've downloaded the interop.tar file from http://technet.oracle.com/products/oracle8i/htdocs/jserver_faq/interop.tar
The problem that I have is that I have not been able to build a client program because login.lib from interop.tar generates conflicts at link time. I've tried everything that I can think of, but I always end up with either missing references or multiply defined symbols. I've tried building using both MS Visual C++ and Borland C++Builder, but with no success.
Has anybody succeeded in building a C++ client? Surely it shouldn't be this difficult?
Thanks,
Tony

Accessing a file on a different server

hi...can you please give me some idea on how to access a file on a remote server?
i just need to open that file on that server and append some data to it everytime someone calls my program?
I just know the ip address of that remote server and the path of that file..
tia
Edited by: hari786 on Aug 5, 2008 12:52 PM

You have to have a program on your computer that connects to the Internet, and sends some data to the other computer. Then you have to place a program on the remote server that will connect to the Internet, listen to it, receive the data from your computer, and then append the data to the remote file. This tutorial shows you how to do that:
[http://java.sun.com/docs/books/tutorial/networking/index.html]
You can't do all of this from your computer only - imagine the results if any computer (yours) could connect to any other computer (mine!!) it wanted to, and then wrote any data it wanted into my computer. That would not be nice.

Unable to access web setup from 4 different Win7 machines with IE9 / FireFox

I Hope someone can help, I suspect this may have something to do with a recent update to Windows or IE since this worked at least a couple of months ago.
I'm unable to access the web setup screen from 4 different windows machines running IE 9 or Firefox (various combinations of wireless, wired, etc.). When I get to the certificate error and hit the "yes, i understand, continue", it comes back with a 'can't be reached' page and looking into the details says the 'connection was dropped'. However If I connect from a MacBook / safari, I'm able to reach the page fine (and admin the router).
Summary:
Using a wrt610n
I am connected to the router, the ip address hasn't changed, the password hasn't changed
I can use the router & connect to the internet
I have the router set to require HTTPS, but switching it to allow HTTP doesn't help.
Both Wired & Wireless Win 7 / IE9 machines can't connect.
Tried setting the router ip address to 'trusted' zone in IE
Tried setting the router ip address to the 'compatibility' mode in IE
Tried using latest version of Firefox with the same results.
Thanks in Advance!
Stephen

Before I suggest you any troubleshooting steps, I would like to ask few question. Like did you try opening the “https://192.168.1.1” in Internet Explorer 8. If not, then try to open the Router Management page in the same manner in Internet Explorer 8 and check whether it opens or not. As it should show up.

thanks in advanced.

Dear Murali,
Try this
a)Start transaction SXI_CACHE.
b)From the context menu XI Runtime Cache select Start Complete Cache Refresh.
If you still face issue try this .
Many actions require to access System Landscape Directory content from the Integration Builder. To optimize performance, this content is loaded into a cache so that the System Landscape Directory does not have to be accessed directly each time that System Landscape Directory content is required.
However, this cache is not automatically updated if changes are made to the content of the System Landscape Directory. For this reason that we delete the System Landscape Directory cache if changes have been made to content in the System Landscape Directory. The cache is then filled each time that the System Landscape Directory is accessed. If we log on to the Integration Builder after we have made a change in the SLD, we do not need to delete the SLD cache.
To clear the SLD cache, from the Integration Builder main menu, choose Environment ® Delete Cache for SLD Data.
Once we have deleted the cache for SLD data, accessing objects in the SLD may take longer than usual initially.
