Problem on distributed computing with java..?

My problem is:
I have one server and three clients.Firstly 3 clients sends data simultaneously to the server and should be accessed by the server at the same instant.
Server does some calculations using this data and should broadcast the results to clients.The clients after sending the data to server are engaged with their own work.After the completion of their work they should receive the data sent by the server.
Please suggest the solution.
And also which package/methods should I use for broadcasting Data to clients....

Sockets and threads?

There is no API for this you'd have to run an external command using Process.exec.

Problem while distribute software via Java Web Start

Hi,
I use JWS to distribute my software to the clients. I use apache 2.2 as webserver.
My Problem:
When i put a update a jar on the webserver, the clients have to start JWS twice to get the new file.
First i thought it is a problem with the webserver. So i have restarted the apache after i�ve put the new jar. ... without success.
Are there any settings in JWS which take affect?
Any ideas?
Tom

The default behavior is to timeout if checking for an update takes too much time.
You can add the jnlp element:
<update check="always"/>
and updates will always happen on the forst launch (when client is using Java Web Start 1.6.0 or later, update element will be ignored by earlier versions)

Problem installing program running with Java

When i start to run a program appear a window witj following message: "preparing to run java virtual machine"..after that appear next small window with installshield wizard. When make a transition between this small windows to start to install the program, nothing happens it is he does not make this transition.
I already download the new version without results.
Do have any ideia what could be the problem.?
Thanks
Jorge

Which JRE is bundle inside your application ?
Is it International or US only ??
I have a reason to believe that US version is
throwing NullPointerException when installing it
on windows 2000 server
When you starting the installer, The installer is unpacking the JRE - so check which directory it expanded and than Try running java.exe from the JRE that was installed.
Maybe its currupted, You dont need to run any code
even if your run java.exe without anything the
exception is thrown
If exception is thrown try the international version of JRE

Problems using deployJava.js with Java 7

I found problems which vary by browser to the following script in an HTML page on Windows 7:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
Launch me!!!
<script src="http://www.java.com/js/deployJava.js"></script>
<script>
deployJava.setInstallerType("kernel");
deployJava.createWebStartLaunchButton("yourAppHere.jnlp", '1.7.0');
</script>
</body>
</html>
The problem shows itself when Java 7 is not yet installed. Note: There is no need to have an actual "yourAppHere.jnlp", since the problems surface prior that being a requirement.
Firefox 8.0:
When the Launch button is clicked on Firefox, a brief dialog with a progress bar appear showing a small download. At completion, a Security Warning dialog appears:
"This Java installer did not come from Sun...". The publisher is shown as Oracle America, Inc.
The install proceeds as normal if the user overides the warning (though eventually missing a real jnlp will catch up with you). I do not know for sure but suspect the problem is with deployJava.js. One fixing this might also want to consider the implications MacOSX port when it is up and ready.
IE 9.0.3:
This browser is a total failure. The initial download dialog progresses to the end, then remains & the session is hung. The dialog is modal, so the only escape other than the power button is killing it via Task Manager.
I am pretty sure these are bugs, but thought would see if others can reproduce Just save html to a file on desktop & double-click. Have these already been reported? Are there other tests that would be good? It has been years since I reported a Java bug, are there directions?

Before un-installing anything except the 1.7.0 JRE from a previous test, I did a search deployJava1.dll, I found 5. All show File Version 6.0.290.11 on the details tab of the properties dialog. That is not to say they are all the same file. I installed a 64 bit JDK, and apparently a 32 bit JRE. I do not remember exactly how I did that. Using the Process Explorer & clicking on the binoculars to find deployJava.dll, it shows that one being used is in C:\Windows\SysWOW64. I am really starting to hate having a JRE built into a JDK. Here is the list:
1- 513KB 11/7/2011 C:\Program Files\Java\jre6\bin
2- 513KB 11/7/2011 C:\Window\System32
3- 513KB 11/7/2011 C:\Program Files\Java\jdk1.6.0_29\jre\bin
4- 461KB 10/3/2011 C:\Program Files (x86)\Java\jre6\bin
5- 461KB 10/3/2011 C:\Windows\SysWOW64
FYI, checks for npDeployJava1.dll were consistent with above, though some were in a new_plugin sub dir. Also, FireFox is x86, not amd64.
Removing the JDK6 Update 29 (64-bit) knocked out #3.
Removing Java(TM) 6 Update 29 (64-bit) knocked out #1.
Removing Java(TM) 6 Update 29 knocked out # 4.
That leaves 2 & 5 still in place (Did not find any let over npDeployJava1.dll's). Nuked them manaully.
Still found a references to deployJava1.dll in registry, which were ripped out @
HKEY_CLASSES_ROOT\CLSID\{CAFEEFAC-DEC7-0000-0000-ABCDEFFEDCBA}\InprocServer32
HKEY_CLASSES_ROOT\CLSID\{CAFEEFAC-DEC7-0000-0001-ABCDEFFEDCBA}\InprocServer32
This registry pattern seemed to be repeated, just kept deleting.
Have a clean system, and am now retrying the tests, BUT IT TRIES TO RUN jre-6u29-windows-i586-iftw-k.exe INSTEAD! I actually followed through for IE & 1.6 is what gets installed NOT 1.7. This is by far the worst. The other stuff might just be because of that stupid JRE instead the JDK. Double checked both the html & JNLP they are still asking for 1.7. Is this a bug or somehow intentional?

ID is a NUMBER and id.toString() is not a number, for
example it ca be a null reference.
well we tryed also this version :
ps.setLong(1, id.longValue());
moreover the exception wasn't thrown for the value of id :56 but was thrown for the value of id : 88. Hence I think it is a case of something other than my code.

Hi I have a geometry problem.Can anyone help with java code

Hi I have a non simple polygon . My job is to make it a simple. for that First I need to find the intersecting lines say line AB intersects line CD. If so then I must replace AB & CD with AC & BD or AD or BC which ever keeps the polygon closed . So can anyone help me out with this code

Hi I am sorry I could explain you properly . Ok
My program gives me a polygon(as you can see when u
run this program)But the polygon is a non simple
polygon.So to make this polygon we must remove all
the crossings betweeen edges in the polygon.The
algorithm which i gave will remove all the crossings
and make the polygon simple.You did not give an algorithm!
SO my job is to take the
existing code and implement the algorithm for this
program in the Createsimpelpolygon() function. For
this First the program must find whether two edges
cross if they cross then swap the vertices like
replace AB & CD with AC & BD or AD & BC.Which ever
keeps the polygon closed . Still not entirely clear to me. You cannot just go and replace vertexes from a polygon: that way you'll end up with a different polygon.
So as we go on we find the
many crossings and iterate the algorithm on all the
crossings until we get simple polygon.Like I said: I don't really understand what it is you're after. You did not respond to my suggestions, so I gather it is not what you're after?
What about Polygon Tessellation (Google for it)? Perhaps that's what you want.
Also, why do you not create a (or use java.awt's) Point class and a Polygon class which holds a java.util.Set of Point's? Your current code looks rather messy.

Disconnected Distributed Computing in Java

Hi, the organization I work for is heavily into JSP/Servlet applications. However, there are a large number of computers which have very slow network links, so they want to find some technology in which we can develop applications which are disconnected, then do a mass synchronization with a Servlet every hour or evening etc.
Is there a Java technology which:
1. application source is centralized and downloadable to client
2. allow for disconnected use of the application
3. synchronize with the server when the application becomes connected with the server
thanks
Don

Jini, is for application to application communication over hetrogenous networks and object protocols. It does not manage distribution of application or synchronization of application data for limited connection applications.

Problems securing WSRP portlet with Java keystore

Hi.
I am following the tutorial in the webcenter developer guide to secure my WSRP (jsr-168) portlet using WS-security.
I have set-up my Java keystore for the producer and consumer with a trial CA certificate from verisign.
The producer.jks looks like this:
Keystore type: jks
Keystore provider: SUN
Your keystore contains 1 entry
consumer, Apr 19, 2007, trustedCertEntry,
Certificate fingerprint (MD5): 09:0E:0B:B9:62:A7:87:E8:A1:6F:10:A3:2D:75:12:2D
The producer store contains one alias, namely consumer.
I have copied the producer.cer and jks to a sub-dir of the application directory in the embedded Oracle webcenter OC4J server dir:
C:\jdevs\jdev10132\jdev\extensions\oracle.adfp.seededoc4j.10.1.3.2.0\j2ee\home\applications\webcenter-advanced\jks
In the EM console I want to configure the keystore (application-scoped) and signature settings for the WSRP markup service. However, after I specify the right keystore settings and alias for the signature (consumer) and click on ok I get the error message that the alias consumer does not exists in the keystore...
Am I missing a crucial step here or am I doing something wrong.
Hope you can help me
Kind regards
-Tom

Hello
I am not sure to see what could be the issue...
Do you have a simple portlet not secured in the provider ? And does this one works ?
If not you probably have a issue with the Registration URL, is this URL is correct ? Does the Portal middle tier can access the provider server ? (proxy, FW, ... can be installed between the portal and the provider and do not allow the portal to call this provider)

Having problem setting system property with java -D name = value

I want some clarification. Consider the statement below
java -Djava.rmi.server.codebase=file:/c:\public_html\classes/
-Djava.rmi.server.hostname=xyz.com
-Djava.security.policy=java.policy engine.ComputeEngine
1. Is the syntax right for specifying a file directory as codebase?
-Djava.rmi.server.codebase=file:/c:\public_html\classes/
2. What does this hostname property imply? Does this mean that the program which is started can be accesed by xyz.com?
-Djava.rmi.server.hostname=xyz.com

Have a problem using flex ui with Java application

Hi, I have a built a Flex UI for a java project. The UI has
some forms which use a servlet for POST and data populated from
servlet. I have used HTTP service to make the calls. I have built
my application i.e UI in Flex Builder and when I run my application
from flex builder everything works fine i.e data populated
correctly..
But when I open the projects folder and run the html file
generated the Http Service does not happen. Can anybody tell me why
is this so?? . Moreover I want use this UI for my already existing
java project. So what all files (i,e. html, mxml, swf) will be
required to be copied to my java project for the UI to work ..
.Thanks in advance...

Hi,
I have been using SWIG-1.3.29 to Wrap C into Java.I hava interface file ie "example.i" and java File
"main.java". Now i set the path
     JAVA_INCLUE
     C:\Program Files\Java\jdk1.5.0_01\include;
     JAVA_BIN
     C:\Program Files\Java\jdk1.5.0_01\bin;
and set java.library.path=.;D:\........\example.i;%path%;
     1.Now In Command Prompt
          Swig -java -example.i
     2. Swig makes "example.java", "example_wrap.c","exampleJNI.java".
     3.Compile the java file
     4.After Compilation i try to run the java program ,the following exception is occuring.
          java.lang.UnsatisfiedLinkError: no example in java.library.path
