Hosting a Java TCP/IP Sever

Hello, I have been doing some research and the more I read the more I get confused about this topic. Also I'm not sure if I put this in the right topic, so I'm sorry if this is the wrong topic.
I would like to professionally host a Server application very similar to the sample Knock-Knock Server on Sun's Site http://java.sun.com/docs/books/tutorial/networking/sockets/clientServer.html.
I was looking at using Tomcat, but I am not sure this is what it was designed to do. Reading about Servlets I seem to get the idea that it is only meant for dynamically generating web content.
My system looks something like this
-Multiple Clients
-Multi-thread TCP/IP server being hosted by some professional hosting service
-SQL data base
I was originally looking at using Servlet technology because I would like to make some modifications to my database using a web form, but I think I could also do this using PHP instead, unless there is a clean way to a Servlet to my TCP/IP server on the same machine.
So my question is, what kind of tool would I use to professionally host my TCP/IP server? I have read about Tomcat and JBOSS a little bit so far, but the more I read the more confused I get about the subject. I am new to the hosting realm and need a little direction :)
P.S. Duke reward points for anyone who can answer quickly and thouroghly if you want them!

Ok, Maybe I'm finally starting to answer my own question. So let me know if I'm on the right track.
I can use some sort of Java hosting solution, lets say for this example I want to use http://s43.eatj.com/
I then need to create a WAR file which from what I have read so far is similar to a plain old JAR file. Then I should be able to upload my WARed application and let it run?
If that's right are there any good tutorials with good explanations of WAR files for newbies?
Thanks!

Problem has been occured on java v1.7.0_65 and v1.8.0_40, MacOS 10.10.2. On previous version MacOS 10.9.5 it works well.
What's going on? How it is possible that host is reachable by curl and unreachable from java.
Also, I've tried to play around -Djava.net.preferIPv6Addresses=true and -Djava.net.preferIPv4Stack=false and it couldn't help.

Using the code you supplied I was able to reproduce your errors. I've adjusted it accordingly and can connect to one of my 10.2 test databases.
import java.sql.*;
import oracle.jdbc.*;
import oracle.jdbc.pool.*;
class Conn {
public static void main (String args []) throws SQLException
    Connection conn = null;
    OracleDataSource ods = new OracleDataSource();
    // ods.setURL(" jdbc:oracle:thin:@localhost:1521:TEST");
    // conn = ods.getConnection("scott", "tiger");
    ods.setURL("jdbc:oracle:thin:@localhost:1521:TEST");
    conn = ods.getConnection("scott", "tiger");
    Statement stmt = conn.createStatement();
    ResultSet rset = stmt.executeQuery("select BANNER from SYS.V_$VERSION");
    while (rset.next())
        System.out.println (rset.getString(1));   // Print col 1
    stmt.close();
}There are several different ways to configure OracleDataSources:

So, hopefully it's just a mismatch config.

SAPehp tool does not know the host for Java stack

I am running SAPehp tool to apply enhp2 to a dual stack with
ABAP and JAVA on seperated Windows boxes.
I started SAPehp at the ABAP box.
Because there is no way to tell where is the Java host, how do I apply
the enhp2 to the Java side? How to make ABAP and Java in sync?
Please help.
Thanks!

Hi Christy,
I consider that both of your ABAP and Java system has separate database. If this is the case then you have to upgrade both system separately and run EHPI installer on both system. You can upgrade the system in same way as you are doing for your ABAP system only difference is the support packages and rest of the main things are same.
I will recommend you to study upgrade guides for ABAP and Java system.
If your ABAP and Java system has different SID but share same database (i.e. MCOD system) then run EHPI installer for upgrade once a time. It means that when you will upgrade the ABAP stack then don't run EHPI tool to upgrade Java stack at same time. Once ABAP system upgrade finished then upgrade Java system. And vice-versa.
Thanks

Java TCP/UDP

In java tutorial, it was said when using TCP, connection based connection, the port number will be automatically assigned. Is there any method that the port can be manually assigned?
Regards
Alpha

I know that i no need to assign a port.
But i don't why : when the program start to run in the first time, e.g. automatically assigned port 2000, then i run it 1 more time(the 2nd time), a warning message said couldn't open local port 2001, when i run it in 3rd time, it success again, the message shows it is using port 2002. Then i tried again(the 4th), it automatic assign port 2003 for me, the warning message said couldn't create local port : 2003, At last, i tried the 5th times, it was success again, it is using the port 2004.
Why have this phenomenon ? How can i solve it?
Regards

How to control tcp connection with java tcp socket programing ??

Hi,
I am connecting a server as using java socket programming.
When server close the connection (socket object) as using close() method ,
I can not detect this and My program continue sending data as if there is a connection with server.
How to catch the closing connection ( socket ) with java socket programming.
My Client program is as following :
import java.io.PrintWriter;
import java.net.Socket;
public class client
public client()
   * @param args
public static void main(String[] args)
    Socket socket=null;
    PrintWriter pw=null;
    try
                      socket = new Socket("localhost",5555);
                      pw = new PrintWriter(socket.getOutputStream(),true);
                      int i=0;
                      while (true)
                        i++;
                        pw.println(i+". message is being send.");
                        Thread.sleep(5000);
    } catch (Exception ex)
                      ex.printStackTrace();
    } finally
                      try
                        if(pw!=null)pw.close();
                        if(socket!=null)socket.close();
                      } catch (Exception ex)
                        ex.printStackTrace();
                      } finally
}

I changed the code as following. But I couldn't catch the EOFException when I read from the socket. How can I catch this exception ?

Can I use jaxm to build java/tcp based distributed apps?

I�m interested in exploiting the capabilities of messaging providers in a standard tcp-based distributed app. Is it possible or jaxm/soap is http based?

JAXM can be http based if you use the SOAPConnection.

Java TCP/IP Web Applet.

I was wondering if there are any great resources on the internet or otherwise to learn how to program a Java App that will enable people to conect to it thru the internet.

The way you connect to it is by using ServerSocket and Socket (this may be obvious). Those classes are quite easy to use. Your subject said it was an applet; applets can only create a socket back to their originating server. So you should check the tutorial mentioned before for threads, servers, and sockets.

Best Azure service to host scalable java executeable?

We have a system currently in demo mode that is a Web API that uses Process.Start to run a .jar file and read its standard out which is JSON. This is not very scalable because each process can consume hundreds of megs of memory each time it spins up. With
all the various services that Azure offers I am unsure of what the best way to expose this .jar as a scalable service.
I know this is a subjective question, but I don't know where else to go. Thank you.

Hi,
This is a very subjective question indeed, my suggestion would be to use the Cloud Service Web/Worker role to implement your solution.
you can refer to the following links that gives more details on the different services so that you make your decision on the best service that suits your needs.

Help needed !! Java TCP

The server side behaves like as album of images, when clients needs to brows an image, he just send image id over the network. Then server sends this image to client which it is displayed there.
i know i should use ObjectInputStream and objectOutStream to send and receive images as objects
i tried to solve it but i didn't work with me
can any one help me please !!

still not sure what the problem is...
can you do
//on the server:
String path = "c:/some/path/porn.jpg";
File f = new File(path);
HashMap map = new HashMap();
map.put(path, f);
//get some image for the client:
String pathFromClient = getPathFromClient(); //some function that you write
File image = (File)map.get(pathFromClient);
if(image != null){
setImageToClient(image); //some function you write
}

The TCP/IP connection to the host 127.0.0.1 , port 1433 has failed

hi all,
i am using SQL2005 server as my database server. i am trying to connect this server in java (i mean using JDBC). i am using windows authentication to connect my sqlserver.
i have the url connection like this
DriverManager.getConnection("jdbc:sqlserver://127.0.0.1\\SQL2005/database name",username","password");
i am trying to connect the server using the above URL, but i couldn't connect it throws an error as the following.
The TCP/IP connection to the host 127.0.0.1 , port 1433 has failed. Error: "Connection refused: connect. Verify the connection properties, check that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port, and that no firewall is blocking TCP connections to the port.".
could anyone plz help me to make the connection in right way.
i have tried to ping via telnet as well, even telnot not able to connect
plz help me...
thanks

Hi,
Besides Madhu mentioned, please check the TCP/IP port number of the instance of SQL Server.
1. Open SQL Server Configuration Manager, and then expand SQL Server 2005 Network Configuration.
2. Click Protocols for InstanceName, and then make sure TCP/IP is enabled in the right panel and double-click TCP/IP.
3. On the Protocol tab, notice the value of the Listen All item.
4. Click the IP Addresses tab:
If the value of Listen All is yes, the TCP/IP port number for this instance of SQL Server 2005 is the value of the TCP Dynamic Ports item under IPAll.
If the value of Listen All is no, the TCP/IP port number for this instance of SQL Server 2005 is the value of the TCP Dynamic Ports item for a specific IP address.
5. Make sure the TCP Port is 1433.
6. Click OK.
If there are any more questions, please let me know.
Thanks.

CVI RT (Real Time) - HOST TCP/IP Communication

Hi,
I am using CVI 2012 Real Time with PXI hardware. I am using TCP/IP communication b/n RT and Host. RT is server and Host is client. In my application, after TCP connection is established between client and server, client will send a command , take for example "GET_DATA" to RT, RT has to respond to that by sending that data.
I am successful in
Establishing RT-Host TCP communication ( I am able to see that host is reading the welcome message sent by RT).
Host is sending the command "GET_DATA" to RT.
RT is receiving the "GET_DATA" command from Host.
In TCP server call back function, in TCP_DATAREADY event, i am using ServerTCPRead() to read data from Host. After reading the data, i am comparing the data with expected command and based on that i will be sending the data using ServerTCPWrite().
RT is reading the command from Host, but it is not writing the data to client. I am not sure whether I can use ServerTCPWrite() in TCP Server call back function.
I also tried using multithreaded concept, but not getting success.
Please suggest any solution for this.
Thanks,
Haari

Hey Rashid,

Java running host command - moved from PL/SQL forums

Oracle Database 11g Enterprise Edition Release 11.1.0.6.0 - 64bit Production
PL/SQL Release 11.1.0.6.0 - Production

Hi,
I am not familiar with Java setting in Oracle
I have a a stored procedure that call a java program to execute host command like
ssh user1@localhost '/home/user1/someprogram'
if we execute this directly using PuTTY
we can do the following with no problem
su - oracle
ssh user1@localhost '/home/user1/someprogram'
but when we execute the stored procedure,
we have to do
*/usr/bin/ssh* user1@localhost '/home/user1/someprogram'
does anybody where to set the path or environment to make the java know the path correctly.
thanks
ps:. this is happen after we recently upgraded our Oracle from 9.2.0.8 to 11.1.0.6

I tried with:
I Navigated to owb_home/owb/bin/admin; Edited the file jdbcdriver.properties; Replaced driver=thin with driver=oci and Restarted the reposinst. But I did not work.
And Default Configuration for External Procedures is OK.
Any another idea?
Thanks for all!
