Friends,
I installed IBM explorer 7.1 which have server and GUI. Locally I connected the queue using inter process communication. Now I need to connect the server QM from remote machine using java standalone program.
In server I have created a queue, port and server channel. when I trying to connect using host name , unable to get the connection. Is this the right way?. else I have to install client where I tried connect that server.but getting error code 2035 when i run that java program. listener and queue manage is running in remote machine. Some forum i seen that AMQCLCHL.TAB file using for client connection. I had confusion whether i have to use that for client connection. if yes how i can use that?

I'm trying to run selenium/java scripts on remote server using windows remote desktop connection. I'm pretty new to these things.
I got two ideas in my mind one is to use selenium grid and another one is to use sockets for connecting.
I'm running this script for 404 validation over 1000 urls. I have the code that'll run fine in my local machine but due to frequent network issues my organization wants to run on remote server.
I got access for that server on port 3389 and credentials for remote desktop connection.
Now how to do this?
I deployed my app on Heroku. It is a simple app that will throw back the message sent from its client version (running on my PC) back to the client. My server app prints the IP address of the machine it's running on so I can connect to it from my client . I do get to see the IP address of Heroku machine when I deploy and run it. However, I am not able to connect to it from my client version using that IP address(Connection timed out) . I have allowed the port I am using in my firewalls. I don't understand what I am doing wrong .
Pls help me solve it.
If you need to see my code let me know ( the app works fine locally on different terminals so I don't think it has a problem).
Your Heroku dyno (an isolated server) is behind a router. You can't use the IP address to connect to it.
Instead, you the URL https://[appname].herokuapp.com where "[appname]" is the name of your app.
You can also run heroku open from the command line.
At the moment i have an android client app which connects to my java server through socket - serversocket. It sends and receive strings. The java server is connected to a mysql database (actually mariadb) using the jdbc driver.
I succeed to create a jbossas application and upload the code of the java server to openshift, but i didn't find any detailed tutorial on how do i connect to this new uploaded server from my socket client (This one (RMI or socket connection to Java Program on OpenShift) gives some tips but i'm still stucked).
More on this, how do i know that my server runs just fine on openshift and how do i control de calls to the database after i connect it (found this: $ rhc app create MyApp jbossas-7
$ rhc cartridge add mysql-5.5 -a MyApp), using org.mariadb.jdbc.Driver and java.sql is still working ?
Any small guide or tip is highly appreciated. I'm new to these things so please don't be too heavy on comments.
You can only make connections to your OpenShift server on http/https or ws/wss ports. If you want to connect to your java application and pull data from it from an android device, I would suggest using a RESTful api or a servlet, etc.
I had similar problem: My app server originally was running as a ServerSocket listener, and any clients/devices connect to it directly via Socket binding.
To deploy it into OpenShift, my previous initial solution was to change its host:port configuration by following the suggestion as described in this link [Socket connection to Java Program on OpenShift]. It worked nice as far as my app server was successfully up and running. But it did not work well with the port forwarding approach in order to accept remote requests.
So for the final solution, I modified the app server by wrapping my original code with a RESTful webservice around it, and deploy it as a web service.
I use H2 Database as DBMS from a remote computer,so I enabled remote access from a browser as follows:
webAllowOthers=true
but when i try to connect to the server from my java application i get this error from H2:
remote connections to this server are not allowed
screenshot:
And also already looking into the code Analyzer with (Error Code: 90117):
REMOTE_CONNECTION_NOT_ALLOWED = 90117
The error with code 90117 is thrown when trying to connect to a TCP server from another machine, if remote connections are not allowed. To allow remote connections, start the TCP server using the option -tcpAllowOthers as in:
java org.h2.tools.Server -tcp -tcpAllowOthers
Or, when starting the server from an application, use:
Server server = Server.createTcpServer("-tcpAllowOthers");
server.start();
I do not understand how to activate the tcpAllowOthers, it does not exist in .h2.server.properties ?
There are two different server:
the Web Console server that is used to run the H2 Console tool (the GUI tool). It can be accessed by a browser only.
the TCP server that allows to connect an application that uses JDBC, when using the client/server mode (jdbc:h2:tcp://localhost/~/test)
The file .h2.server.properties is only used for the Web Console server. It only supports webAllowOthers=true. This file is not used by the TCP server.
To enable remote access to the TCP server, you need to start the TCP server using the option -tcpAllowOthers. To start both the Web Console server (the H2 Console tool) and the TCP server with remote connections enabled, you would need to use:
java -jar h2*.jar -web -webAllowOthers -tcp -tcpAllowOthers -browser
(this also starts a browser)
I'm testing a client-server based Java application where a specific scenario involves having both the client and server running on the same host (i.e., the client connects to the server running on localhost). This seems to work fine except for when I test this scenario on a virtual machine (running 32bit Windows 7) using VirtualBox.
Note: Everything henceforth is running inside the virtual machine. I start the server and try to connect to it using the client but the connection times out. Surprisingly, I tried connecting to the server using putty and the connection behaved as expected. Both the Java client and putty tried to connect to localhost - the client failed but putty succeeded.
Does anyone have a possible explanation for why this might be happening?
Note: This is not a duplicate of Addressing localhost from a virtualbox virtual machine
How do you connect to the localhost? By connecting to the hostname "localhost"? You could try connecting to the InetAddress returned by getLocalHost()
