How to establish a trusted connection with JDBC for SQL SERVER 2000

Hi!I am using jdk 1.4 and eclipse 3.3.
I create a servlet in eclipse with in-build tomcat.
When I run it ,it was working perfectlly has it was suppose to work.
In this servlet I connect to a sql 2000 database using jdbc-odbc bridge driver.
But when I tried to deploy the servlet on tomcat 5.5 manully on the same machine ,it gave me error saying
[Microsoft][SQLServer JDBC Driver][SQLServer]Login failed
for user 'sa'
I searched around some post and found that ok ,I need trusted connection
But I have 2 Questions
1). Why was in eclipse I was able to connect to the SQL server and why not in the servlet which I deployed manully on tomcat.
2). How do I create a trusted connection with JDBC for SQL server 2000
Thnaks for your help in advance.

Hi! duffymo ,QussayNajjar ,dvohra09 .
Thank for help.
The ideas are really great.
I am trying generate reports for my company.
When I used eclipse the code worked perfectly.
below is code which I used
out.println("Calling For Class Name<br>");
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
out.println("Calling For Class Name success Now calling database <br>");
1). jdbcConnection = DriverManager.getConnection("jdbc:odbc:SQLJasper");
2). jdbcConnection = DriverManager.getConnection("jdbc:odbc:Driver={SQL Server};Server=ServerName;Database=tempdb");
3). jdbcConnection = DriverManager.getConnection("jdbc:odbc:Driver={SQL Server};Server=ServerName;Database=tempdb","UID=UserName","Password=Password");
out.println("connecting to database success<br>");
I had tried to connect the database using this three way.
In 1st I tried using DSN name .
Next 2 self explainer for expert like you.
I used to 2nd variant to connect in eclipse and it worked fine.
I not an expert in java ,I just doing some research on jasperReport.
My best guest is that eclipse is using some library files of which I have no clue.
Thank's for your help,I appretiate it.
Once again thank a billion.
Sorry for the messy righting.

Connection with remote computer

I want to write a program that checks the status of remote machines continuously whether they are on or off. Which method i should use

@Ian: I agree. You could easily implement a multi-cast (or similar) heartbeat solution if you control the machines and can ensure the heartbeat is running via a scheduler or other means.
But if you simply want to write a standalone program to check other machines without installing software on them, I could see that being more problematic. You might be able to come up with an O/S specific solution or assume certain programs are always installed. But there are problems in each of those methodologies, IMO.

Establishing a socket connection between a .swf file and a socket-test program (TCP/IP builder - Windows), in AS3.

I have an issue with a college project I'm working on.
Using Actionscript 3, I made a simple .swf program, an animated, interactive smiley, that 'reacts' to number inputs in a input-box.
For the sake of the project, I now need to make the framework for establishing a socket connection with the smiley .swf, and another program.
This is where I encounter issues. I have very little knowledge of AS3 programming, so I'm not certain how to establish the connection - what's required code-wise for it, that is.
To test the connection, I'm attempting to use the "TCP/IP builder" program from windows, which lets me set up a server socket. I need to program the .swf file into a client - to recognize it, connect to it, then be able to receive data (so that the data can then be used to have the smiley 'react' to it - like how it does now with the input-box, only 'automatically' as it gets the data rather than by manual input).
My attempts at coding it are as follows, using a tutorial (linked HERE):
//SOCKET STUFF GOES HERE
    var socket:XMLSocket;
    stage.addEventListener(MouseEvent.CLICK, doConnect);
// This one connects to local, port 9001, and applies event listeners
    function doConnect(evt:MouseEvent):void
    stage.removeEventListener(MouseEvent.CLICK, doConnect);
    socket = new XMLSocket("127.0.0.1", 9001);
    socket.addEventListener(Event.CONNECT, onConnect);
    socket.addEventListener(IOErrorEvent.IO_ERROR, onError);
// This traces the connection (lets us see it happened, or failed)
    function onConnect(evt:Event):void
        trace("Connected");
        socket.removeEventListener(Event.CONNECT, onConnect);
        socket.removeEventListener(IOErrorEvent.IO_ERROR, onError);
        socket.addEventListener(DataEvent.DATA, onDataReceived);
        socket.addEventListener(Event.CLOSE, onSocketClose);
        stage.addEventListener(KeyboardEvent.KEY_UP, keyUp);
    function onError(evt:IOErrorEvent):void
        trace("Connect failed");
        socket.removeEventListener(Event.CONNECT, onConnect);
        socket.removeEventListener(IOErrorEvent.IO_ERROR, onError);
        stage.addEventListener(MouseEvent.CLICK, doConnect);
// Here, the flash tracks what keyboard button is pressed.
// If 'q' is pressed, the connection ends.
        function keyUp(evt:KeyboardEvent):void
        if (evt.keyCode == 81) // the key code for q is 81
            socket.send("exit");
        else
            socket.send(evt.keyCode);
// This one should handle the data we get from the server.
        function onDataReceived(evt:DataEvent):void
        try {
            trace("From Server:", evt.data );
        catch (e:Error) {
            trace('error');
    function onSocketClose(evt:Event):void
        trace("Connection Closed");
        stage.removeEventListener(KeyboardEvent.KEY_UP, keyUp);
        socket.removeEventListener(Event.CLOSE, onSocketClose);
        socket.removeEventListener(DataEvent.DATA, onDataReceived);
Trying to connect to the socket gives me either no result (other than a 'connection failed' message when I click the .swf), or the following error:
Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: file:///C|/Users/Marko/Desktop/Završni/Flash%20documents/Smiley%5FTCP%5FIP%5Fv4.swf cannot load data from 127.0.0.1:9001.
    at Smiley_TCP_IP_v4_fla::MainTimeline/doConnect()[Smiley_TCP_IP_v4_fla.MainTimeline::frame1:12]

Tried adding that particular integer code, ended up with either errors ("use of unspecified variable" and "implicit coercion") , or no effect whatsoever (despite tracing it).
Noticed as well that the earlier socket code had the following for byte reading:
"sock.bytesAvailable > 0" (reads any positive number)
...rather than your new:
"sock.bytesAvailable != 0" (reads any negative/positive number)
Any difference as far as stability/avoiding bugs goes?
So then, I tried something different: Have the program turn the "msg" string variable, into a "sentnumber" number variable. This seemed to work nicely, tracing a NaN for text (expected), or tracing the number of an actual number.
I also did a few alterations to the input box - it now no longer needs the 'enter' key to do the calculation, it updates the animation after any key release.
With all this considered and the requirements of the project, I now have a few goals I want to achieve for the client, in the following order of priority:
1) Have the "sentnumber" number variable be recognized by the inputbox layer, so that it puts it into the input box. So in effect, it goes: Connect -> Send data that is number (NaN's ignored) -> number put into input box -> key press on client makes animation react. I optionally might need a way to limit the number of digits that the animation reacts to (right now it uses 1-3 digit numbers, so if I get sent a huge number, it might cause issues).
- If the NaN can't be ignored (breaks the math/calculus code or some other crash), I need some way of 'restricting' the data it reads to not include NaN's that might be sent.
- Or for simplicity, should I just detect the traced "NaN" output, reacting by setting the number variable to be "0" in such cases?
2) After achieving 1), I'll need to have the process be automatic - not requiring a keyboard presses from the client, but happening instantly once the data is sent during a working connection.
- Can this be done by copying the huge amounts of math/calculus code from the inputbox layer, into the socket layer, right under where I create the "sentnumber" variable, and modifying it delicately?
3) The connection still has some usability and user issues - since the connection happens only once, on frame 1, it only connects if I already have a listening server when I run the client, and client can't re-connect if the server socket doesn't restart itself.
I believe to do this, I need to make the connection happen on demand, rather than once at the start.
For the project's requirement, I also need to allow client users to define the IP / port it's going to connect to (since the only alternative so far is editing the client in flash pro).
In other words, I need to make a "Connect" button and two textboxes (for IP and port, respectively), which do the following:
- On pressing "Connect", the button sets whatever is in the text boxes as the address of the IP and port the socket will connect to, then connects to that address without issues (or with a error message if it can't due to wrong IP/port).
- The connection needs to work for non-local addresses. Not sure if it can yet.
- On re-pressing connect, the previous socket is closed, then creates a new socket (with new IP/port, if that was altered)
It seems like making the button should be as simple as putting the existing socket code under the function of a button, but it also seems like it's going to cause issues similar to the 'looping frames' error.
4) Optional addition: Have a scrolling textbox like the AIR server has, to track what the connection is doing on-the-fly.
The end result would be a client that allows user to input IP/Port, connects on button press (optionally tracking/display what the socket is doing via scrollbox), automatically alters the smiley based on what numbers are sent whilst the connection lasts, and on subsequent button presses, makes a new connection after closing off the previous one.
Dropbox link to new client version:
https://www.dropbox.com/s/ybaa8zi4i6d7u6a/Smiley_TCP_IP_v7.fla?dl=0
So, starting from 1), can I, and how can I, get the number variable recognized by "inputbox" layer's code? It keeps giving me 'unrecognized variable' errors.

Can't establish a sftp connection with the finder

Hi, I'm trying to establish a sftp connection with the finder (using the "Connect to server" feature) between my (recently purchased) Mac Mini (mid 2011: i5, 2.3 GHz, 2 GB, running 10.7.3) and a Debian Testing box and I can't, I get the following error:
'There was a problem connecting to the server "ip.address"
This file server will not allow any additional users to log on. Try to connect again later.'
However if I try establishing a connection from the terminal (either ssh or sftp) it works flawlessly:

Connected to ip.address.
sftp>
I've searched for a fix or alternative on the internet and I haven't found one that works; The one that keeps coming up is to try: "ftps" as the protocol instead of "sftp" with the remaining information the same (it doesn't work, it gets the same error message afterwards).
The IP address and login information works (corroborated by the fact that I can log in from the terminal from the Mac Mini) so the only issue is with the finder capabilities for establishing the connection. I have looked for apple related documentation or How Tos but I haven't found anything useful.
I don't want to use any third party app or tweak because of the sensitive information that is going to be transfered, I would like to be using strictly the tools from the OS.
If you need any more information please let me know, any help is deeply appreciated.

I have the same issue although i kind of fixed it. I have two admin accounts and one of the account's safari did the same thing as yours, except, it was the startpage and everypage i tried to visit. I reseted safari, as in the erase all data safari in the toolbar, safari-Reset Safari... But safari still didn't work. I logged out and went to my other account and opened safari. Now it works fine on both accounts. This meant safari had to logout before actually working better. I have this a few times these days.

Dynamically create Variant Data Socket items with multiple writers

I want to use variant or cluster items with data socket connection. I want to allow multiple writers.
So far I can create these items dynamically but not set them to allow multiple writers.
For numeric, string, and Boolean items I can set these properties by predefining them in the data socket server manager. I could not predefine a variant or cluster in the manager.
I realize I can flatten to string the item needed but would prefer to do this in the cluster or variant formats.
Any suggestions?

Could you accomplish this using a functional global architecture??
An interesting concept which might work and did just open up a new host of possibilities!
When I get the time I might give this a try. I just did a quick test in another program.
Through VI server I opened a reference to a remote machine. I then created strictly typed reference to a âfunctional global viâ that I knew would be in memory. It reads the functional global just fine!
Thanks for the suggestion.
Here is the work around I used for the data socket program.
Here is the original problem.
I needed to know on the server side when a new value was written to the message cluster, which consisted of a string and a variant. Checking the string portion of the cluster let me know what command to send the device being controlled on the server machine. The variant is used to hold the various parameters that accompanied the command. Since the same command type could be sent several times I needed to reset the string control after the server read the command. This required writing to the data socket from the client & server machine (multiple writers). Also since the client could be any PC in the subnet I needed to allow all these machines to have write access.
I solved this by using a second data socket item for the new message flag. This item is a string value that could be pre-defined and set to allow multiple writers. I then used the cluster item to handle the commands and wrote to the string item a signal that a new command was ready. The server then recognizes a new command is ready, reads the command, and then flags the string message received.
Thanks again for those who took the time to answer this.

Why am I getting an error "Unable to establish a secure connection with (mail server)"? And what can I do?

I'm trying to set up email on my Firefox OS Flame (OS is Boot2Gecko 2.0.0.0-prerelease) and getting an error:
Unable to establish a secure connection with mail.velociraptor.info
I'm on Dreamhost, the certificate belongs to `*.dreamhost.com` but I'm not even sure this is a certificate error, and if it is, how I'd go about fixing it. I found the Certificate Manger, but I don't know how to download the certificate and add it, and I don't know if this is even the problem.

If this is a self-signed certificate or one where the CA is not trusted on FFOS, you will get this error.
There is currently no proper user interface for adding certificates. You could have a look at the method described at this page: http://www.pending.io/add-cacert-root-certificate-to-firefox-os/
There are also several bugs open regarding this problem, e.g. https://bugzilla.mozilla.org/show_bug.cgi?id=874346. They have additional information that could help you to find out, if this is the problem you are seeing.

How can i get my printer to connect with my computer to print?

I have a HP photosmart prem-web C309n-s printer. I have two different computers. One is a 4 year old HP laptop, and I just recently purchased an HP touchsmart 320 PC. I installed the printer when I first got this computer, and the printing worked fine from any computer that was in the house. Now, it seems that my printer is not connected with my computer. With my dad's laptop in the house, he had before installed the printer, and when I look up the network on my printer, the only computer that it shows connection with is his. I need to print things for class, and I'm not sure how to make my desktop "visible" to my printer. Please help!!!!

I wander how to establish Webdispatcher on EP with HTTPS

I wander how to establish Webdispatcher on EP with HTTPS . I
can do it for HTTP. I found releated link in SAP Library:
http://help.sap.com/saphelp_nw04/helpdata/en/d8/a922d7f45f11d5996e00508b5d5211/frameset.htm
but still I do not understand as installation sapwebdisp -bootstap asks me only for HTTP port of mesage server , instance nr for web dispatcher and HTTP port number for SAP webdispatcher.
How to deal with HTTPS?
In library (under SAP Web Dispatcher and SSL ) it is mentioned for HTTPS-HTTPS: icm/server_port_<xx>= ... PROT=HTTPS ...
wdisp/ssl_encrypt=1. Is it in sapwebdisp.pfl? I guess also on EP something should be done(I have a productive system and I would not like to spoil anything)

Is it in sapwebdisp.pfl?
Yes.
I have a productive system and I would not like to spoil anything)
You should setup the QAS environment to support webdispatcher and https first.
Be aware, that there are three different methods for https:
client https> webdispatcher -http-> SAP system
client https> webdispatcher -https-> SAP system (decrypt on webdispatcher and re-encrypt to SAP system)
client https> webdispatcher -https-> SAP system (no decryption on webdispatcher)
Often the first version is sufficient and the simplest one...
