Runnig multiple JVMs to simulate network via rmi

Hello
We runing rmi client and server from one computer the code files in the same directory
javac *java
rmic FileImpl
start rmiregistry
java -Djava.security.policy=policy.txt FileServerafter that we start a client
java FileClient kuku.txt 127.0.0.1Does we intiate several JVMs by starting client and server if not how to intiate JVM for each client and server?

I want that one of my servers will also act as client so I need run from the same JVM? How can I do that?You can't not do it. Just instantiate your server, then when it does Naming.lookup() or invokes a remote method it is being a client. In the same JVM. In the same object.
But can I create several remote objects on the same JVM? Yes, just create and export them all.

Can multiple Airport Expresses be connected via ethernet to an Airport Extreme to extend a single WiFi Network?

I am a big fan of both the Airport Extreme and Airport Express. In my work environment, I need to create a good quality single wireless network around 2 large aircraft hangars and some offices at the perimeters. We have a good quality wired Cat5e ethernet network extended between the buildings and offices now. Is this possible and does it seem like a good practical solution? I think that 4 or 5 Airport expresses would easily provide good wireless coverage in the needed areas.

Can multiple AirPort Expresses be connected via ethernet to an AirPort Extreme to extend a single WiFi Network?
Yes, this will work just fine as long as any individual Ethernet cable run will not exceed much over 330 feet or about 100 meters.

Will multiple Lan cards cause problems using rmi?

Will multiple Lan cards cause problems using rmi? If a host has two or more network cards (only one of which is Internet-enabled), how does RMI know which IP address to use? There seems to be a problem when such a client registers with an RMI service, and has a client-side callback method invoked by the server.

You can tell RMI the address you want by defining java.rmi.server.hostname at the JVM which exports the remote object.

Singletons across multiple JVMs

I have an EJB application container which is spread across multiple JVMs(something like a clustered EJB container). I am using a Singleton class to hand out 'running serial numbers'. Therefore there is a Singleton class per JVM(which is not very clean but i chose this path in the absence of anything better). Each singleton comes up when it is first invoked within a JVM and reads a starting running number and a pool of numbers from the database. This way multiple Singletons will not step on each other when doling out the serial numbers and there is no need to go back to the database for every request to the 'running serial number'.
Is there some way to do some of the initialization within these Singleton's just ONCE across the multiple instances of the JVM ie. a real Singleton across multiple JVMs?
Thanks

Pranav,
thanks for your suggestions.
the idea of using a Session bean to access a serialized object was one of my design options when i first implemented this, but then i decided against it because of the overhead of having to make an RMI call for every request to the 'running serial number'. The application being written is for a performance benchmark, and the request to the number being done at least once for every transaction, I chose to use Singletons.
It is a clustered EJB container(not like most conatiners), in the sense that a single container is spread across multiple JVMs.
Now if your application is getting clustured
then you have a problem, in that what you can do is
what object you have made put it in JNDI context and
everytime you want to edit it pull it out edit and set
it back. This will act a your singleton object in
clustured environment accross JVM'sI did not fully understand the second part of your solution????

Send a ResultSet object via RMI - won't work.

Hi. I make a user interface to access MySQL database. The access to MySQL server is done from a remote location via RMI. The process to delete/update/create was succeed. The only problem is when I try to get(from the client computer) the ResultSet object, that come from invoking statementObject.executeQuery(myQuery) method, from the server Computer: it won't work. It said that the ResultSet object is not serialized(it is an interface). I need the ResultSet object for my client program since I will use it to set my AbstractTableModel class's object. Last goal is to put the AbstractTableModel object into the JTable constructor so I can see the result from a table.
Is anyone can help me? I can not return the ResultSet object to the client since it is not serialized.

I use the following solution using List. As List is Serlizable I can throw it across the network using RMI... it is also of course easy to access.......
For users objects you need to throw across the network just simply make them implement Serializable
In your ORM class accessing the DB:
public List getSQLResults{
Resultset SQLResults = statement.executeQuery(SQLQuery);
Vector results = new Vector();
while (SQLResults.next()){
// create class object here if needed...
results.add(SQLResults.getStrinf("COL_NAME");
return results;In your GUI class..
JTable theTable = new JTable();
DefaultTableModel theModel = new DefaultTableModel();
theModel.addColumn(SOME_COLUMN);
try{
List resultsData = ORMClass.getSQLResults();
Iterator iterator = List.Iterator();
while(iterator.hasNext()){
iterator.next();
theTableModel.addRow(SOME_OBJECT);
theTable.setModel(theModel);
catch(Exception ex){
// exception rasied...... do something!!!
}

Urgent help:send image over network using rmi

hi all,
i have few question about send image using rmi.
1) should i use ByteArrayOutputStream to convert image into byte array before i send over network or just use fileinputstream to convert image into byte array like what i have done as below?
public class RemoteServerImpl extends UnicastRemoteObject implements RemoteServer
public RemoteServerImpl() throws RemoteException
public byte[] getimage() throws RemoteException
 try{
 // capture the whole screen
 BufferedImage screencapture = new Robot().createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()) );
 // Save as JPEG
 File file = new File("screencapture.jpg");
 ImageIO.write(screencapture, "jpg", file);
 byte[] fileByteContent = null;
 fileByteContent = getImageStream("screencapture.jpg");
 return fileByteContent;
 catch(IOException ex)
public byte[] getImageStream(String fname) // local method
 String fileName = fname;
 FileInputStream fileInputStream = null;
 byte[] fileByteContent = null;
 try
 int count = 0;
 fileInputStream = new FileInputStream(fileName); // Obtains input bytes from a file.
 fileByteContent = new byte[fileInputStream.available()]; // Assign size to byte array.
 while (fileInputStream.available()>0) // Correcting file content bytes, and put them into the byte array.
 fileByteContent[count]=(byte)fileInputStream.read();
 count++;
 catch (IOException fnfe)
 return fileByteContent;
}2)if what i done is wrong,can somebody give me guide?else if correct ,then how can i rebuild the image from the byte array and put it in a JLable?i now must use FileOuputStream but how?can anyone answer me or simple code?
thanks in advance..

Hi! well a had the same problem sending an image trough RMI.. To solve this i just read the image file into a byte Array and send the array to the client, and then the client creates an imegeIcon from the byte Array containing the image.. Below is the example function ton read the file to a byte Array (on the server) and the function to convert it to a an imageIcon (on the client).
// Returns the contents of the file in a byte array.
 public static byte[] getBytesFromFile(File file) throws IOException {
 InputStream is = new FileInputStream(file);
 // Get the size of the file
 long length = file.length();
 // You cannot create an array using a long type.
 // It needs to be an int type.
 // Before converting to an int type, check
 // to ensure that file is not larger than Integer.MAX_VALUE.
 if (length > Integer.MAX_VALUE) {
 // File is too large
 // Create the byte array to hold the data
 byte[] bytes = new byte[(int)length];
 // Read in the bytes
 int offset = 0;
 int numRead = 0;
 while (offset < bytes.length
 && (numRead=is.read(bytes, offset, bytes.length-offset)) >= 0) {
 offset += numRead;
 // Ensure all the bytes have been read in
 if (offset < bytes.length) {
 throw new IOException("Could not completely read file "+file.getName());
 // Close the input stream and return bytes
 is.close();
 return bytes;
 }to use this function simply use something like this
public byte[] getImage(){
byte[] imageData;
 File file = new File("pic.jpg");
 // Change pic.jpg for the name of your file (duh)
 try{
 imageData = getBytesFromFile(file);
 // Send to client via RMI
 return imageData;
 }catch(IOException ioe){
 // Handle exception
 return null; // or whatever you want..
}and then on the client you could call a function like this
public ImageIcon getImageFromServer(){
 try{
 // get the image from the RMI server
 byte[] imgBytes = myServerObject.getImage();
 // Create an imageIcon from the Array of bytes
 ImageIcon ii = new ImageIcon(imgBytes);
 return ii;
 }catch(Exception e){
 // Handle some error..
 // If yo get here probably something went wrong with the server
 // like File Not Found or something like that..
 e.printStackTrace();
 return null;
}Hope it helps you..

Can I share one iTunes Library with multiple computers on a network?

Can I share one iTunes Library with multiple computers on a network?
note: one library universally shared, not Home Sharing (one library each, shared to each.)
I want to share one library stores on my server and access it through various local computers. When I buy a song from a computer (non-server), I want it to be added to the library (stored on server). I want it to auto copy to my server, for organization. I want to be able to sync my phone from any computer.
Most of this I can do, if i figure out how to use one universal library for all my computers.
Any ideas how I can do this?

eyeinit,
You can authorize your iTunes account on up to 5 computers at a time.
However, purchased music is downloaded to the first machine to download it, but these articles have more information on moving your music between authorized computers:

This one is for moving all your music using an iPod as a storage drive

Apple TV Gen 2.. Terribly Slow Streaming From Wired Home Network via itunes Windows 7. Please Help

Hello all, I just signed up for this as i hope to get more results from here than i did waiting 4 hours for a call from apple today.
I recently purchased an Apple TV Gen 2.. installed it on my Samsung 40" HDTV via HDMI cable and also ran a network cable to my basement where my router, (Linksys 5 port router plus Wireless) is mounted on the wall beside the cable modem.
just to rule things out i will give some spec's and details before i get further into this.
My goal is to use my Desktop Homebuilt PC running windows 7 ultimate 64bit to store my Digital Movie Library and stream through itunes all of my digital media to my Apple TV located in another room. Both Apple TV and my desktop windows 7 PC are hard wired NOT WIRELESS.
My internet connection is cable and tested it this evening several times at 58.9 Megabits per second down and 8 Megabits per second down... (yes that is correct 58mb/s down. this equates to about 7.1 megabytes per second download speeds for reference.
Now just to rule out my 2 year old wireless router i went and purchased a brand new router today... Same results.
Now on to the problem details and my findings.
Using my Desktop PC wired to try and stream Itunes movies from the streaming is absurdly slow.. very slow... i have yet to wait to see what happens after 30 minutes of waiting for a Movie to start.. music also takes a long time to load...
Music... i can go to icloud funtion which i paid for today.. and click on the same song in icloud and the song starts almost instantly, so does music videos...
Also previously purchased TV shows starts playing from the cloud almost instantly as well even HD TV shows...
Trying to stream anything through my desktop windows 7 pc just doesnt work right...
I have narrowed this problem down to my desktop.. but can not figure out what the problem is...
using my macbook air 120GB SSD wireless over the same network, which i also have a mirrored copy of my itunes library for testing purposes... there is zero issues with streaming anything from my macbook air over the same network via wifi...
Also using my ipad 2 mirroring works flawlessly, even HD movies plays without a hitch... same goes for my iphone 4s
the only issues i am having are with my desktop and streaming from my itunes libary on it... i do not want to use my macbook air.. as that defeats the purpose of having apple TV.. in the future i plan on ripping my entire DVD / Blueray collection to a 3 TB hard drive and stream to my AppleTV... from my desktop computer storing my entire DVD / Blue Ray library digitally on the 3TB hard drive....
But i can not get this to work... i can see my itunes libary on my desktop.. i can play music and watch movies.. other than anything HD will not play... but everything takes a rediculously long time to load... i can download an entire movie with my 58mb's connection in the time it takes to load something streaming from my itunes libary on my desktop PC...
if anyone has any suggestions.. there may be something i have overlooked or i am missing. any input and or advice will be greatly appriciated.
Thanks,

Ok.. in order to help other users i will post this..
I have resolved the issue... it was rather simple and dumb...
I never use windows media player ever.. i do not like it and can not stand it.. because in my case it was a brand new windows installation this fix will only apply to certain users..
because it was a brand new windows installation.. i had never clicked on windows media player.. apparently streaming settings are embedded into windows media player for the windows 7 OS...    in past installations that i have used for years.. i simply never ever clicked on windows media player, as i never had a reason to.. i use itunes for my ipad, iphone etc.. etc...
by accident and shear luck i decided to click on windows media player.. and of course go through the express settings.... after i did this all of my streaming problems to my apple tv gen2 disapeared... HD movies now start almost instantly... so as i stated above apparently there are media streaming settings embedded into the OS through windows media player... doesnt make any sense to me as i never use the program.. but whatever that fixed my issue..
so for any of you windows 7 people out there using a windows 7 pc as your itunes sync computer and using that itunes library to stream to your apple tv... make sure you have done the initial setup at min.. of windows media player.. i still left itunes as my default player.... everything now works flawlessly... infact for whatever reason.. even in an HD movie my network almost has half the movie synced now accross the bar before the movie starts so now my apple tv is blazing fast....
i have been struggling with this for 2 days now and simply never gave it a thought that windows media player would ever have anything to do with itunes streaming a totally seperate program.. but it did..
i hope this helps other people with similar problems.
good luck

Using the same library with multiple computers over a network Use Aperture

Hi Everyone. I am researching some cataloguing/editing programs to recommend one to my boss, and I was wondering if it was possible to use the same library between multiple computers on a network. Does anyone know if this is possible? This may be what makes or breaks the decision on whether or not to go with Aperture as we need a program that can access a large database of photos on multiple computers.
Thank you.

Welcome to the forum.
You can do it, but...
It's not supported by Apple.
Performance won't be great unless you're running a really fast network.
If more than one person tries to access the Library at one time you're likely to end up with a corrupted database, and there's no code in Aperture to limit access to one person at a time.
The Library must be stored on an HFS+ volume - don't even try putting it on a FAT32-formatted drive.
If you want 'proper' multi-concurrent-user network-enabled cataloguing software you're looking into a whole different level of investment than the low price of Aperture - think more in terms of thousands or even tens of thousands of dollars.

Setting up Bridge for multiple users on a network

New Bridge user here
Can anyone give me some advice on how to set up Bridge for use by multiple users over a network / server?
We have a large image bank stored on a server and ideally if any one user adds keywords or other metadata to an image I would like the rest of the users to be able to view that data and be able to use it in searches. AS more than one user could add keywords at any time I was wondering is it possible to set up a central keyword file or cache so any updates are available to all users.
Do I set up a shared cache? What happens if it becomes corrupted and has to be rebuilt, do the keywords disappear as well?
Are the keywords associated with that particular cache or are they stored in a separate file?
Thanks,
Hazel

Curt
how do you know if your using the
Central cache all distributed cache ?
and are they both stored in the same place ?

Multiple JVMs foe One WL6.1 instance

Hi,
Is it possible to attach multiple JVMs to an instance of WLS6.1
so that all JVMs will be self sufficient in serving client requests....
If it is possible then any pointers in that direction..???

Each WL server runs in one JVM. If you want to have 4 JVMs, then run 4 WL
servers in one cluster.

Is it possible to attach multiple JVMs to an instance of WLS6.1
so that all JVMs will be self sufficient in serving client
requests....
>>>
If it is possible then any pointers in that direction..???

Multiple JVMs

Hi,
Can I run multiple JVMs on the same machie.
If I can, then what are the repurcussions of this.
Spark

I am happily using several JVM's on my Linux box:
1.1.8
1.2.2
1.3.1
1.4.1
The only thing I have to do when switching from one to the other is to adjust PATH.

Authorization Error While Invoking BPEL Process Via RMI

Hi All,
I have been trying to invoke BPEL Process via RMI client.
I use the following piece of code for BPEL Process Invocation...
public class RMIClient {
public RMIClient() {
public static void main(String[] args){
Hashtable jndi = new Hashtable ();
jndi.put (Context.PROVIDER_URL, "opmn:ormi://host:6010:oc4j_soa/orabpel");
jndi.put (Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
jndi.put (Context.SECURITY_PRINCIPAL,"oc4jadmin"); // username of Bpel Manager
jndi.put (Context.SECURITY_CREDENTIALS,"welcome1"); //password of BPEL Manager
Locator locator=null;
try {
locator = new Locator("default",jndi);
} catch (ServerException e) {
e.printStackTrace();
IDeliveryService deliveryService =
(IDeliveryService)locator.lookupService
(IDeliveryService.SERVICE_NAME );
// construct the normalized message and send to oracle bpel process
NormalizedMessage nm = new NormalizedMessage( );
String xml = "<ns1:MyFirstBPELProjectProcessRequest xmlns:ns1=\"http://xmlns.oracle.com/MyFirstBPELProject\">\n" +
" <ns1:input></ns1:input>\n" +
" </ns1:MyFirstBPELProjectProcessRequest>";
nm.addPart("payload", xml );
NormalizedMessage res=null;
try {
res = deliveryService.request("MyFirstBPELProject", "process", nm);
} catch (ServerException e) {
e.printStackTrace();
} catch (RemoteException e) {
e.printStackTrace();
Map payload = res.getPayload();
When I try to connect to my locally deployed BPEL process Manager and Invoke the same process (MyFirstBPELProjectProcess ) it works fine and creates an Instance on BPEL Process Manager Console.
When I tried Invoking the same BPEL process (MyFirstBPELProjectProcess ) deployed on a Remote machine ,it doesnt create an Instance.
I believe my connections settings are all correct ,since it doesnt give me an connection issue on my standalone client.
I tried looking at the following file default_group~oc4j_soa~default_group~1.log available opmn folder under SOA Suite OAS and there
are no errors.
Could some body point the log files that I need to look at.
I am sort of clueless...

CAn you post the error. HAve you made sure that the remote machine has connection on the port 6010. You can test this with the folloing command from the remote machine
telnet host 6010
obviously replace host with the fully qualified host name of the SOA machine.

MBP no longer connects to network via Airport

today my MBP will not connect to my network via airport. Several other apple devices connect to the network no problem. MBP connects to the network OK via ethernet cable.
When I try to connect it just keep prompting for network password & user password, generates spinning wheel but then returns invalid password dialogue box. Tried several times and no success - occasionally there is an additional dialogue box " Apple80211agent......."
Pass word is fine as 5 other devices connect without any issue. What is going on?
Incidentally, just thought to create another Airport connection and hey presto it connects.
Still confused.

Your local LAN runs through your router.
All your ethernet ports, and your modem and router, should be behind and filtered from excess current. That means a UPS generally. And run input line thru UPS (coax) first, then run RJ45 back through UPS again (there can still be excess surge or current on the line).
Modems and routers can be compromised by surge outage or storm. So can ethernet ports.
You have two ethernet ports and you tried with both also.
What you did not do that I would have added is SMC Reset / Reset NVRAM/PRAM.
This is what I have had for the last year, very nice and stronger signals thruout the house.
