plz help me out
thanks

I am just use that ...But it works...!!
MySQL is Runing good ...
the problem is that you must reset the defaultDS,
to be Mysql.
So,Jboss must have only one DefaultDS,
In My Setup...
1.standardjaws.xml
<?xml version="1.0" encoding="UTF-8"?>
<jaws>
<datasource>java:/mySQL</datasource>
2.jboss.jcml (must changed as followed)

OpenOffice Base - MySQL with JDBC connection

I was using MySQL with ODBC connection, but cannot do all MySQL queries. In OO Forum says dev version does with JDBC.
http://www.oooforum.org/forum/viewtopic.phtml?t=41301
I am now using OpenOffice dev version. I am a bit lost when asked to install MySQL JDBC Driver Class:
com.mysql.jdbc.Driver
Is the driver a part of jre package or to be installed from somewhere?

I downloaded, but don't know where and how to install or use it. Took a look at the documentation, seems it requires only to untar but something has to be pointed. I think its something simple but I am overlooking.

This thread tells how to do...

Problems with SSH: Connection Refused

Greetings fellow Arch users,
I have hit a bit of a snag that I could really use some extra help getting around. I've tried everything I can think of (and everything that Google thought might work) and I have my back rather against a wall, so I thought I'd come here to see if anyone can offer some advice.
To make a long story short, I am a college student and am attempting to set up an ssh server on a desktop at my house so I can access it remotely from the college. I have the computer set up and the server running, however I am having difficulty making connections to it from my laptop. I know that the server is running, because I can log into it both from the server itself (sshing into local host) and from my laptop when I use the internal IP address.
The server is on a static IP address within the network(192.168.0.75), and my router is configured to forward TCP port 1500 to it (I'm using 1500 as the port for my ssh server). However, when I attempt to log into the ssh server using my network's external IP address, the connection is refused. I used nmap to scan my network and found that, even though the proper ports are forwarded to the proper place as far as my Router's configuration interface is concerned, port 1500 is not listed as one of the open TCP ports. I also, to test it, temporarily disabled the firewalls on both the server and the client. That didn't help. The command that I am running is:
ssh -p 1500 douglas@[external ip address
As I am really not sure what is causing this problem, I don't know what information to provide. So here is everything that my inexperienced mind sees as likely being important. If you need anything more, let me know and I will do my best to provide it.
Here is the sshd_config file from my server.

Thank you guys ahead of time. Getting this server operational is hardly critical, it is just a side project of mine, but I would really like to see it working.

Okay, so I finally have the opportunity to try and log in from a remote network. And. . . it doesn't work. Which is just my luck because I now need to wait an entire week, at least, before I can touch the server again. Anyway, running ssh with the maximum verbosity I get this output:
douglas ~ $ ssh -vvv -p 2000 address
OpenSSH_6.3, OpenSSL 1.0.1e 11 Feb 2013
debug1: Reading configuration data /home/douglas/.ssh/config

debug1: Connecting to address [address] port 2000.
debug1: connect to address address port 2000: Connection timed out
ssh: connect to host address port 2000: Connection timed out
It takes a minute or two for the command to finish with the connection timeout, as one would expect. And yes, I am reasonably sure that the address that I am using is my home network's external IP. It is dynamic, but I checked it before I left which was just over an hour ago. I guess that it may have changed. I'll know that for sure in the morning, when my server sends me an automatic email with the network's current address. In the meantime I am operating under the assumption that the address I am using is correct. What else could be the problem?

ADF Mobile App integration with webservices, connection refused error

I created an ADF application for department search with business components and exposed this as a webservice. I can access the WSDL locally from a browser. Then created an ADF mobile application and deployed it to android emulator. I am able to deploy the application to emulator and I can see the app on Android emulator. When I try to search for any department, I am getting "cannot connect to localhost on port 7101 : connection refused". My server is started already and the port number is also correct. Did any one came across this issue before? Even the WSDL URL is not accessible from the browser of android emulator.
Edited by: adf_forum on Nov 16, 2012 2:16 PM

Hi,
One more thing to keep in mind is that Android emulator is itself a network host, and localhost will likely loop back into itself, i.e. emulator. Please try to set up the WLS to listen on an actual IP address for your development machine, create your WS DC using this real IP address, and then try to deploy/run the app.
If you need to retrofit your app with an new IP address, please keep in mind there are several places you would need to manually fix up, including the connections.xml file.
In general, if the device emulator's browser cannot hit a web service, then the ADF Mobile app will also not be able to hit a web service.
The most reliable way is to treat the emulator like an actual device, then work out your application's connection accordingly.
Thanks,
Joe Huang

How to send a file without getting Connection Refused??

Hello everyone!
I'm developing a FTP (Client and Server) program as a project and I have 2 main problems:

How does FTP work normally? Well in most cases you are talking to a server that is on the internet. This server has been configured to be behind or on a network where the routers are not blocking requests to connect to FTP ports (among other services). So nothing different other than it is configured correctly.
I do suspect your program may have some bugs as well. For example when you talk about it dropping the connection after one transfer. That doesn't sound too great.when i checked the program...no
in the test...yes
so the server has no blocking ports, but what about a client with a router?..how do the programs pass the client blocking?
when i checked the program with a friend (i have a modem and i was the server) all the data was perfectly transfered (moving among folders, deleting files, creation of folders-->all these actions on the server..sending codes, strings and stuff), but when i tried to transfer a file it did connection refused :S
i can bring a link to the file that do the transfer and if you have patience to read

Jdeveloper 11g TP4: Connection refused error for Embedded Oc4j

Hi,
I am getting following error whenever trying to deploy any application in embedded oc4j or whenever try to connect with embedded server on Resource palette.
Error while getting remote MBeanServer for url: ormi://127.0.0.1:23891/default:
Error reading application-client descriptor: Error communicating with server: Connection refused: connect; nested exception is:
     javax.naming.CommunicationException: Connection refused: connect [Root exception is java.net.ConnectException
I am using Jdeveloper 11g TP 4 on windows XP.
I have checked other links too related to above error and have checked following:
Proper host name entry in host file
No spaces in Jdveleoper installed directory name
Proxy setting in Jdeveloper: excluded localhost and ip address
Will be very thankful if anyone can help me to resolve this issue.
Thanks in advance

Don't spend to much time on this. JDev 11g is production and there will be no OC4J 11g!

JBoss connection -- EJB3

I am implemented a entity bean and a session bean.
I am writing a client to test my session bean.
Also, I am using JBoss.
in my cleint class I am trying to connect to my database (local host) but I am having problems with JBoss connection.
I am using SQL server 2005. Any Help would be great so I can get this program to run.
When I start JBoss .. it says that SQL is not bound.
this is the error .. how can I fix that ..
Also, does this mean that I am missing some Jar files.
--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: persistence.units:jar=Demo.jar,unitName=DemoPU
State: FAILED
Reason: javax.naming.NameNotFoundException: SQL not bound
I Depend On:

Depends On Me:
jboss.j2ee:jar=Demo.jar,name=CustomerBean,service=EJB3
jboss.j2ee:jar=Demo.jar,name=KBSessionBean,service=EJB3
Also this is the code I am trying to run..
public class Client {
/** Creates a new instance of Client */
public static void main(String[] args) throws Exception
Connection conn;
// Step 1: Load the JDBC driver.
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

// Step 2: Establish the connection to the database.
String url = "jdbc:sqlserver://localhost:1433;database=jdocxpt";
conn = DriverManager.getConnection(url, "sa", "");
System.out.println("Got Connection.");
Context ctx = getInitialContext();
CustomerRemote c = (CustomerRemote) ctx.lookup("CustomerBean/remote");
TempCustomer first = new TempCustomer();
TempCustomer second = new TempCustomer();
first.setId(15);
first.setName("roro");
second.setId(9);
second.setName("jojo");
c.addCustomer(first);
c.addCustomer(second);
conn.close();
Thanks for your help in advance.

I don't think I totally understand what you are trying to do. If you are testing your session bean why do you get a database connection from your client isn't that the responsibility of the server side?
Anyway, to get JBoss to connect to a database you have to put your jdbc/connector driver in JBoss' server lib directory, (jboss/server/default/lib for example). Then you have to add a configuration file for your datasource in the deploy directory. Have a look here: http://www.onjava.com/pub/a/onjava/2004/02/25/jbossjdbc.html
I hope that is any help!

Connection refused, but works on diff computer

Ok, i'm opening a connection to a web server using ssl (jsse) and this WAS working great. But now when I try to run the same code that was working on this computer (and still works upstairs) i get:
java.net.ConnectException: Connection refused: connect
at java.net.PlainSocketImpl.socketConnect(Native Method)
at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:305)
at ..............
The line of code that is causing this problem is
OutputStream outputStream = null;
outputStream = conn.getOutputStream(); <- RIGHT HERE
the conn was setup and is not null because I can getURL() on it and it's context has been setup, so everything seems to be ok with the connection but once I try to get an output stream it blows with that connection refused exception. I have set doOutput to true aswell:
conn.setDoOutput(true);
Like I said, this code works on a different computer now and used to work on this one. If anyone knows what could have happened to this machine I could appreciate any help.
(used to work but now it doesn't box)
JDK 1.4.1
Intel processor
Windows 2000
(still works box)
JRE 1.4.1 (no jdk)
Intel processor
Windows NT
Thanks a bunch
-Dave

And can you ping the other computer from the one that doesn't work?

What am I doing wrong? The embedded OC4J library is added to the project. I've tried to use the javac compiler. It looks like the OC4J instance cannot make a connection to the db.
Thanks,
Martin

Hello
I've added the connection to the web.xml, but still get the same error.
When I go to embedded OC4J preferences and change the JNDI-names of the datasources (global and current-workspace) to the same name (this was default), i get this error message:

Performance with MySQL and Database connectivity toolbox

Hi!
I'm having quite some problems with the performance of MySQL and Database connectivity toolbox. However, I'm very happy with the ease of using database connectivity toolbox. The background is:
I have 61 variables (ints and floats) which I would like to save in the MySQL-database. This is no problem, however, the loop time increases from 8ms to 50ms when using the database. I have concluded that it has to do with the DB Tools Insert Data.vi and I think that I have some kind of performance issue with this VI. The CPU never reach more the 15% of its maximum performance. I use a default setup and connect through ODBC.
My questions are:
1. I would like to save 61 variables each 8-10ms, is this impossible using this solution?
2. Is there any way of increasing the performance of the DB Tools Insert Data.vi or use any other VI?
3. Is there any way of adjusting the MySQL setup to achieve better performance?
Thank you very much for your time.
Regards,
Mattias

First of all, thank you very much for your time. All of you have been really good support to me.
>> Is your database on a different computer? Does your loop execute 61 times?
Database is on the same computer as the MySQL server.
The loop saves 61 values at once to the database, in one SQL-statement.
I have now added the front panel and block diagram for my test-VI. I have implemented the queue system and separate loops for producer and consumer. However, since the queue is building up faster then the consumer loop consumes values, the queue is building up quite fast and the disc starts working.
The test database table that I add data to is created by a simple:
create table test(aa int, bb char(15));
...I'm sure that this can be improved in some way.
I always open and close the connection to the database "outside the loop". However, it still takes some 40-50 ms to save the data to the database table - so, unfortunatly no progress to far. I currently just want to save the data.
Any more advise will be gratefully accepted.
Regards,
Mattias

Error while deploying module with iasdeploy : Exception while createXmlDocument() : connection refused

Hi to you all,
I work with iAS 6.0 sp2 on Solaris.
For 1 day, I get that exception when trying to deploy or remove my modules (servlets + JSP) with the iasdeploy tool :
Exception while createXmlDocument()
java.net.ConnectException: Connection refused
at java.net.PlainSocketImpl.socketConnect(Native method)
at com.netscape.server.deployment.WebbAppReg.run(compiled code)
at com.netscape.server.deployment.WebbAppReg.main(Unknown source)
The war archive is put in the JAR directory, unpacked in the APPS/modules directory, but the servlets of the module have the null GUID in the registry ({000000 000000 000000}. And so, I have the GX error when trying to invoke them.
What appends ? Is it a iAS process which is unable ?
Please help !
Paul-Emile

I think you have not put the xml files in the war file.
You need to put them under WEB-INF/ directory. Manually generate the guids using kguidgen script and try to deploy the war module. It should work fine. If it doesnot work please send me the file. So that I can further investigate and find out where exactly the problem is.Other wise you can use the deploytool.
Please let me know if this works fine.
Thanks for visiting our web forum.

Perhaps a stupid question: is MySQL running and listening on port 3306? The problem is not always in the webapp. Perhaps you can create a small test class that uses Driver to make a connection to your database.

Connection refused with java, but not javaw

I have a ServerSocket based program...listening on a port. It is really a very simple program. And I can run it with javaw. Then I can use another problem, for example, telnet to connect to that port, just to prove I can connect to that port. Everything is fine.
Now if I run the exactly the same ServerSocket program with java, then I got the connection refused error.
It is weird.
Do you know why? Do you know a good socket troubleshooting tool on Windows? I am afraid of the viruses, so I haven't downloaded any free tools yet.

You're right.
The Norton personal firewall does not handle localhost to localhost correctly. I do all the tests on the same machine. The netstat -an shows the port is listening in either case. But now I know the firewall blocks one of them silently. No rule prompt was triggered. Worse, no logging produced for that particular access.
Thanks. You've been very helpful.
