Java Net Programming

Hello there,
I am recently writting an Client/Server program for my final year project. At the begining i just only think aboout single client access into server. And it works perfectly. Now the requirements changing and ask me to make it multi-client.
Iam using thread to control multi-client and it also work. But when the client1 send information then client2 then back to client1. And so on then socket is closed and data is corrupted because the server doesnot know which client is it talking to. I know that i am using thread not properly. Actually i don't really much understand thread so that why my program doesnot work properly.
I know this is too general question. But from your experience could you suggest me some resource from internet to look up more information about thread. And when using thread to control the connection for client and how do we control the input and output from client and server. Some suggestions please
My programs is based on GUIs and if so should i put thread on the button or menuitem something.
Thanks alot

I think i should use thread because i should enable multiple clients access to my server.
Actually what am i doing is :
I have a server running and client access in make a request to server then feedback the files or whatsoever data that server make and send back to client.
when i run another client. the data send to Server is corrupted because server doesnot know which one is for client 1 or client 2 as i said. If i use thread to control the connections only or control the action between the server and client. Iam not really good at thread so that my server disconnect the client.
What strategy would you use if you doing this. Just in generally
Thanks

MySQL and Java - getting program to work

I am setting up mysql to run sql from a Java program on my pc at home and probably biting off more than I can chew. I get these messages when executing the java program ExecuteSQL.java:

This is what I did.
I created a folder on my C: drive named MySQL.
I downloaded these two zip files form the MySQL website
     * mysql-connector-java-3.0.11-stable
     * mysql-4.0.18-win.zip
Installed both of these in folder MySQL.
I modified this line in the program ("ExecuteSQL" 1st pgm in chapter 17) I got from "Java Examples In a Nutshell" and compiled it into directory jwork.
String driver = "com.mysql.jdbc.driver", url = "jdbc:mysql://", user = "", password = "";
The readme file talks about putting a jar file in $JAVA_HOME/jre/lib/ext.
the word "Java_Home" (I now know) is not literally the name but represents the
name of the folder where the JDK to be used exists. So I put a copy of
mysql-connector-java-3.0.11-stable-bin.jar in folder C:\JDK14/jre/lib/ext.
Then I get a ClassNotFoundException error com.mysql.jdbc.driver.
After finding
http://forum.java.sun.com/thread.jsp?forum=31&thread=439796
and
http://forum.java.sun.com/thread.jsp?forum=31&thread=499888
and others, I copied (a second copy) the jar file to the directory where I am create my java objects.
Then I unzipped it to that directory, creating three folders that hold the unzipped objects.
I tried executing the program again. I get the messages at the top of this post.
The Manifest file is in one of the three folders unzipped to my java work directory.
In the second of the two above threads, jsalonen says:
the problem can be solved by mentioning mysql.jar in the Class-Path attribute
in the manifest of the jar file:
In this "manifest" file, there are only three lines and I added a fourth and it looks like this
(there are two, one in directory MySQL\META-INF and one in directory jwork\META-INF:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.1
Created-By: 1.4.0_01-b03 (Sun Microsystems Inc.)
Main-Class:jwork\ExecuteSQL
How do I "mention" mysql.jar in the class path attribute?
In the index.list file (in the directory with the manifest file, do I need to add anything to refer that "com.mysql.jdbc.driver" is the driver?
Do I need index.list in MySQL\META-INF ?

Inputting an excel file to the java servlet program

Hi,
How can I input an excel file into the java servlet program? I am using POI HSSF programming to read the content of that excel file.I have created a form that will accept the path from the user and in the servlet program, I have called a post method to retrieve the path of the file. I am getting the path of the file as a string.Then I have to access the file to read the data. But it is not working. What should I do?.Please help me.
I have created an html file to create a form that will ask the path of the file to be loaded into the servlet program.Please give me a solution,thanks in advance. The servlet program that receives the file is shown below. It just only take the name of the file and prints if that is ok.

Java Concurrent Program issue

Hello,
I am fairly new the Java Concurrent Programs concept. I was just trying a simple Hello World example but I cannot seem to run it from the operating system. Here is my Hello World java program I created using Jdeveloper:
package oracle.apps.fnd.cp.request;
public class Hello implements JavaConcurrentProgram {
public static final String RCS_ID = "$Header$";
public void runProgram(CpContext ctx) {
ctx.getLogFile().writeln("-- Hello World! --", 0);
ctx.getOutFile().writeln("-- Hello World! --");
ctx.getReqCompletion().setCompletion(ReqCompletion.NORMAL, "");
It compiles fine in Jdev generating the class file. Here is what I did :
1) Created directory under $JAVA_TOP as follows :
mkdir $JAVA_TOP/oracle/apps/fnd/cp/sample
2) moved the Hello.java file there under sample directory
3) compiled java file using avac $JAVA_TOP/oracle/apps/fnd/cp/sample/Hello.java ( It compiles fine generating the class file )
4) Now I wanted to test running it : I tried using jre command first as I saw in other posts but this is not working :
jre -Ddbcfile=$FND_TOP/secure/k021kp-6180_r115dev1.dbc -Drequest.outfile=/export/home/sqadri/outfile oracle.apps.fnd.cp.request.Run oracle.apps.fnd.cp.sample.Hello
Error :
ksh: jre: not found
Then I tried using the other way I saw on posts which is using the java command :
java -cp $AF_CLASSPATH -Ddbcfile=$FND_TOP/secure/k021kp-6180_r115dev1.dbc -Drequest.outfile=/export/home/sqadri/outfile oracle.apps.fnd.cp.request.Run oracle.apps.fnd.cp.sample.Hello
This gives me the following error :

Can anyone tell me what I am doing wrong ? I have tried everything even tried ftp the class file from my local but I get the same error. Any help would be appreciated.
Thanks

Ajay,
Yes you are right. I did not register my java program yet in the concurrent programs.
I thought I could test it out from the operating system command line before registering it. But looking at your document you sent me it seems I have to do all the steps i.e. define concurrent program etc before I can test it from the operating system. If that's the case then what's the use of trying to test it via operating system using
java -cp $AF_CLASSPATH -Ddbcfile=$FND_TOP/secure/k021kp-6180_r115dev1.dbc -Drequest.outfile=/export/home/sqadri/outfile oracle.apps.fnd.cp.request.Run oracle.apps.fnd.cp.sample.Hello
Thanks

How to integrate a class with template.java - Java Concurrent Program. 11i

Hello, I have a java class I got from a vendor. This java class needs to run through as concurrent program. As per metalink note *How To Create a Java Concurrent Program?

Java Concurrent Program - connecting to MS SQL Server

Hi,
I hope this is correct forum to post this question.
I am writing a JCP which will connect to a MS SQL Server DB, pull data from a table and populate this data into a custome table in EBS (R12.1.1) database. But I am facing some issues.
When I run run this concurrent program from EBS, I get following exception message:
Wed Aug 08 01:18:04 GMT 2012: In openConection()
Wed Aug 08 01:18:04 GMT 2012: Before Loading Driver com.microsoft.jdbc.sqlserver.SQLServerDriver
Wed Aug 08 01:18:04 GMT 2012: openConection() ClassNotFoundException: java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver
Wed Aug 08 01:18:04 GMT 2012: Before Calling processPrintMachineRecords()
Wed Aug 08 01:18:04 GMT 2012: Exception:: java.lang.NullPointerException
Wed Aug 08 01:18:04 GMT 2012: In closeSQLServerConnection().......closing JDBC Connection
Wed Aug 08 01:18:04 GMT 2012: Connection object was null, hence skipping close
Wed Aug 08 01:18:04 GMT 2012: After Calling processPrintMachineRecords()
The I read somewhere on internet that I should set CLASSPATH in options field of concurrent program definition. So I provided classpath as follows:
-cp /rs01/u02/applmgr/utyeb02/apps/apps_st/appl/au/12.0.0/appsborg.zip:/rs01/u02/applmgr/utyeb02/apps/apps_st/comn/java/classes/apps.zip:/rs01/u02/applmgr/utyeb02/apps/apps_st/comn/java/classes/sqljdbc_4.0/enu/sqljdbc.jar
In this classpath sqljdbc.jar contains the classes for connecting to MS SQL Server DB. However after giving classpath like this I started getting different error:
Exception in thread "main" java.lang.NoClassDefFoundError: oracle/apps/fnd/cp/request/Run
Caused by: java.lang.ClassNotFoundException: oracle.apps.fnd.cp.request.Run
     at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
     at java.security.AccessController.doPrivileged(Native Method)
     at java.net.URLClassLoader.findClass(URLClassLoader.java:188)

     at java.lang.ClassLoader.loadClass(ClassLoader.java:251)
     at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)
It appears from the error message that after giving this CLASSPATH, program was not able to find the "Run" method itself. In otherwords, CLASSPATH screwed it further.
Can anybody please point out what am I doing wrong here?

who know how to resolve the problem, thank you in advance:)

I do always use the ip adress/port
You can find it by
try {
     ipLocal = InetAddress.getLocalHost();
     catch(Exception e) {
          new PopUpMessage("ERROR","Error in searching IP", true);
system.out.println("Your IP address is " + ipLocal.getHostAddress());

�� I have a java applet program (yanhua.java) need help!!!

�� I have a java applet program (yanhua.java) that use mouse click a area show a fireworks, the applet program that a java fan mail me. Now i find some bug in the program, can you help me? thank in advance!
The backdrop of the question: The yanhua.java applet program works well. But one day, i install j2re 1.4.1 plugin for my microsfot Internet Explorer, i run the yanhua.java applet program again, it show difficult(i move my mouse in the area, slowness), the fireworks is not fluent. Then i try my best to find the cause , i get some information, the following: yanhua.java run in j2re 1.4.1 plugin,it will deplete 100% cpu; else yanhua.java does not run in j2re 1.4.1 plugin, it will deplete 90%--95% cpu too; but my computer c3 1G cpu and 256MB memory, without running other program at that time. So i can have the assurance to say that the yanhua.java have some bug or error. can you help me to find all bug in yanhua.java? thank you very much!!!
i want to solve the question: finding all bug in yanhua.java
NOTE:
1��fireworks show specially good effect(a yanhua.java applet) you can look at:

Facing error wen running Java Concurrent Program to insert data into table

I compiled the program and in the java_top/oracle/apps/../.. (in the pkg given). Now the class files and java files are in the said location. I created an executable of type "java concurent Prog" and location same as Package name.
Created a Program and assigned it to the responsibility. Having done this when i run the CP I find it ends with an error msg. The log files show the below exceptions: "java.lang.ClassNotFound Exception".
We are doing it in R12.0.6 and in Unix server. Pls help me where I am missing it. It turned to be an urgent requirement frm my end.
Thanks,

Java chat programs

hi..am looking for sample java programs where a server can communicate to multiple clients and viseversa....could anyone by any chance have done similar programs or knows a link to such programs?
thanks
ps:i already checked in the forum and found a number of incomplete codes..so i'm looking for something complete.

It doesn't follow any naming convention as i wrote it a long time back when ( I didn't know what coding conventions were then). However it will give you a basic idea

Calling Dot Net program From oracle Database

Hi
is there any way to call DOT NET program Like C# from oracle database, i mean is there way to call it from pl-sql stored procedure or trigger ..etc
I read that is possible with java , C, C++, but is it possible with C#
Best Regards

If your Oracle database is running on Windows and is a reasonably recent version (I believe 10.1 or later), it has the ability to create .Net stored procedures just like you have the ability to create Java stored procedures. That tends not to be a particularly commonly used feature but it's an option. If you compile your .Net application to a DLL, you could also call it as an external procedure.
More commonly, however, if you're talking about a .Net program that is deployed on a middle tier server, however, would be for the .Net application to expose an API (say, a web service API) that the database could invoke (via UTL_DBWS or UTL_HTTP).

MAC OS 10.5.7 FireWall & Java Socket programing

Hi everyone,
I am fighting for few days with a simple problem in vain.
I am programming a simple java client-server application based on TCP sockets but I do not manage to open any socket at all due to a "connection refused" problem:
In the previous versions of MAC OS X Leopard it was possible to open communication port easily. The latest version of leopard no longer support this functionality. Now you can grant permission only to applications (not to java programs).
I tried the following:
Creating a script that starts my application and uses the firewall setup program to grant permission to that script: Impossible only application can be managed neither script nor JAR files are accepted.
Modifying low level firewall parameters using IPFW: useless the MAC firewall works at a lower level. changing local firewall rules does change anything.
I am thinking about modifying the /library/Java/Home/lib/java.security file but I think that it works only for Applets.
I try to grant permissions to the java executable file using the firewall configuration panel but the problem is still present.
I am sure that lots of programers had this problem.. Anyone have a simple solution ?
Thx for your time.
PS: here a simple code example of what I am doing.
try
socket = new Socket(InetAddress.getLocalHost(),port);
catch (UnknownHostException e)
e.printStackTrace();
and the output is:
java.net.ConnectException: Connection refused

I finally got around to rearranging and backing up partitions. Updated to 10.5.7 on a non live partition and then booted into it. Don't have any problems with CS3 ID, IL or PS. And no problem with CS4 ID, IL, PS. Does appear to have fixed the OpenGL problems with the NVIDIA GeForce 8800 GT video card and PSCS4. I will say on the main workstations I have not updated a live booted partition in years. Seems like there are nothing but problem trying to update a live partition.
As to the monitor profile being introduced into the RGB print flow from ID PS3 and 4. Problem still there and still not fixed. But of course you can use Print as Bitmap or if your running a Canon printer with selectable Fast Graphic Process in the driver you can print correct output this way.

Java Card program execution on Eclipse

Hi Dears,
I am new to Java Card. I did setup to run Java Card programs on eclipse using http://eclipse-jcde.sourceforge.net/.
This is my simple program below
import javacard.security.RandomData;
public class Main {
     public void main() {
          RandomData rd = RandomData.getInstance(RandomData.ALG_SECURE_RANDOM);
          short outLen = 10;
          byte buffer[] = new byte[outLen];
          short outOffset = 0;
          rd.generateData(buffer, outOffset, outLen);
Compilation is successful but when I run the program I get the following error.
Error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/String
This is very annoying. I think my run time environment is not ok for running java card programs. I am able to run Java programs but not java card programs. Any one can help please?
Thanks,
Regards,
Naveed

please post code with {code} tags
