Can object transfer over the network without serialization?

Hi all,
Can we send the objects over the network (from clent to server)
without seraializing it?
Thanks in advance

Yes. By sending its values by any other means, like as XML.

Need to send object instances over the network

I found no other way to implement a switch case to cast objects on both sides to solve my problem.
Basically I need to send objects over a network protocol based on XML, the object is sent inside XML
converted in base64, overall encoding of XML is utf-8.
Let's suppose in my network there are 2 peers connected via socket.
I have multiple instances of different types on both peers but I want to keep these instances
synchronized. If something changes on side A, side B must receive that instance and replace
it in the correct place (just one way, from A to B).
When I receive such instance on B I want to cast it to it's proper instance
of it's proper type and I am scratching my head on how could I implement this without some
sort of unique ID table and switch case.
If I had 1 instance per type could it be done easily?
But I need to keep in synch many instances per type.
Is there any dynamic casting that I can trigger based on some type/instanceID information
I could send along the object?

I cannot printany web pages or emails over a wireless home network. My OS is windows 7 and am using an Epson printer. I know I have the home network set up correctly as i can print files over the network.

I cannot print any email or web pages over a wireless home network. I know that I can print my files over this network, just not anything from the web or emails using Firefox. I am using Windows 7 and printing to an Epson.
== This happened ==
Every time Firefox opened
== when I set up the wireless home network.

The most likely reason for this is that the wrong printer is chosen in the File->Print window.
In Firefox, go to File->Print and click the dropdown box with printer names. Ensure that the correct network printer is selected, then try printing again.

Epson Artisan 800 can't scan over the network (wireless)

Hi,
I installed the Artisan 800 all-in-one drivers and software. I can print wirelessly. I looked up Epson scanning setup help. When I open Epson Scan Settings.app, click on "Network", but all the buttons are disbled (unclickable). Therefore, I cannot click "Add" and all the subsequent steps. I tried adding the app to the "incoming allowed" list in Firewall, disabled the Firewall entirely, but to no avail. Funny thing is, it was working a couple of months ago when I had the printer new, but since then I have installed a couple of OS X updates (I believe I had 10.5.5 when it was working). In the intervening period, I also messed around with the OS X supplied Printer drivers (deleted a whole bunch of files, not sure if some required files were deleted), and I noted that the recent 10.5.7 update (and possibly 10.5.6 before) did not restore those files. However today I uninstalled all the Epson drivers/files using the A800 supplied CD, and reinstalled everything. I even tried installing the scanner files from Epson's webpage. Nothing worked. Please suggest something!

i had a similar problem -I connected by printer to an iMac via a network cable to a Time Machine 802.111 router. Could print but not scan. I could only get the scan functions working by setting up the wireless connection on the printer. But then I could not print until i reconnected the network cable between the printer and the TIme capsule. Tel support from Epson seemed more confused than me!
Should I have to have the printer networked by cable as well as wireless? That seems silly. I must be missing a step in one of the setups.

SL can't print over the network to Epson AcuLaser CX11NF

I create a bonjour print queue in snow leopard to the Epson AcuLaser CX11NF and it fails to print with with Yellow Triangle Unable to connect ot printer; will try in 30 seconds
Then I get the following error
/Library/Printers/EPSON/LaserPrinter/GD2/filter/pdftoescpage.app/Contents/MacOS/ pdftoescpage failed
On the same network with another MAC running OS X 10.5.x it an print no trouble. Also if I connect to the 10.5.x shared printer I can print from SL.
I just updated to 10.6.1 and it didn't fix a thing.
I can print if I directly connect via a USB cable to the printer.
Why is printing so broken in SL, did they ship it before they completed development and testing ?

This may or may not be of help to Snow Leopard users, but printing to my CX11NF via the USB port on my Airport Extreme (the first n version, not the current one) is problematic but workable from both my Dual G5 and my wife's 15 inch MacBook Pro (late 2008), both running Leopard. There were no issues with Tiger, but Leopard introduced an incompatibility with Epson Status Monitor3. ESM3 crashes or freezes after any print job (or queue of print jobs), and this usually results in having to restart either the Mac or the Airport Extreme. I've found that manually quitting the Epson AL-CX11 driver, then quitting or, more often, force quitting the ESM3 after a print job allows subsequent printing without having to restart. (I do this using Dock menus.) The workaround isn't 100 percent successful, but it comes reasonably close. As this printer has been discontinued for a couple years now, Epson is extremely unlikely to update drivers for it. So far, I'm reluctant to upgrade my wife's MBP to Snow Leopard, as there's no way to know in advance if it will defeat the workaround. If anyone using Snow Leopard has success printing through an Airport Extreme's USB port to the CX11NF, please post it here.

Can't scan over the network after clean windows 8 install

My wife's hard drive recently crashed (it was Windows 7 32bit). I replaced the drive and installed Windows 8 64bit, and then upgraded to 8.1. I did the 8.1 update before I installed any software (i.e., canon drivers).
Everything seems to work fine but when we try to scan to her pc via the wireless network we get the error message. We are initiating the scan from the device panel.
MP Navigator EX corresponding to the printer you intend to use, may not be installed correctly. Reinstall MP Navigator EX, and then try again.
I've uninstalled and re-installed several times. Tried running as administrator. There aren't many settings to change in the Navigator software. I'll attach some screen shots. If you need any more information let me know. Any help at all would be great. If we can't get it working we'll probably scrap the thing and get something else.
Thanks!!!

I suggest uninstalling the full feature software from both PCs and re-installing and configuring the software on both.
Are you using the HP Solution center to scan? It is in Dutch, but the images are the same as what you should see in a correctly installed full feature software package.

Sending Connection Object over the Network using RMI

Hi,
How can a Connection object be sent over the network and run on another JVM. I need to hold connection object to execute processes one after other, that require Oracle connection without ever connecting again. I do not have J2EE container or webserver setup to hold connection/connectionpool,but need to run the process on command line. I am using RMI infrastructure to pass parameters/return values but connection object is not serializable and connot be marshalled and failing. Please explain, if there is another way using JDK 1.4
Sudheer

I think that what you want to do is connect to the database on the RMI server object, then use the server object from your remote clients to execute the processes you require to rrun.

I don't believe this is possible. A connection object has a number of associated structures on the operating system, which generally makes it impossible to move. From a fundamental networking level, you also cannot, in general, cause a connection to machine1 to start communicating with machine2-- that would introduce all manner of security problems.
Why don't you want to just create another connection on the other machine?

Can you share a USB hard drive over the network through an Airport Express?

After asking a few individuals at my local Apple Store, I have been consistantly told that I can plug in a usb hard drive into the bottom of my airport express and share it over the network.
However, after making sure my airport express has the latest firmware (6.3) and even donwloading and installing the airport disk utility I still am not having any luck getting my HFS (journaled) usb 2.0 hard drive to be visible on the network.
I have also noticed that when following the instructions on this apple support document (http://docs.info.apple.com/article.html?path=AirportUtility/5.1/en/ap2108.html) that when I get to step 3, the option to click disks is grayed out. I assume this supports my theory that the airport express won't share hard drives, can anyone confirm?
Am I doing something wrong? Or were the reps at my store mistaken and the only hardware that can share a hard drive is the airport extreme not express?
Thanks

Thanks for the swift reply.
Continuing my investigation I started to come to the conclusion you just mentioned. I am surprised none of the staff at my store realized this. However, at least I know now.
The basis for me looking to this is... With leopard on the eve of its release, I wanted to get a large network accessible storage solution that would allow my wife's and I's Macbook pros to use time machine on the network drive when we were at home. Since we rarely use our laptops while sitting at a desk connected to an external drive, I figured this would be a great idea and started to look into various NAS solutions.
Surprisingly, most generic (netgear, western digital) network drives require you use proprietary software to connect to them, and are only compatible with windows xp. After seeing the options the airport extreme opens up in terms of network storage I figured it would be the best bet.
Do you have any other suggestions besides getting an airport extreme? I would rather not have to buy a full blown mac that I have to leave on 24/7 to share the drives. Or do you see any possible pitfalls to this idea? Such as, would time machine forget to use the network drive after a while since it wouldn't always be available to it when away from home?

Never mind, I already found the solution myself.
What I did wrong was:
- not copying the master image to the nbi folder
- selecting the netinstall-restore.dmg image as source to copy to my HD.
The thing is, when you create a netinstall image for 10.5, the image itself is already included in the netinstall image so you don't have to do anything else.
With the 10.4 image however, you also have to copy the master image to the NetBootSP0 directory.
In the *.nbi folder contains an netinstall-restore.dmg file. But that is only to boot you to netrestore, it's not the image itself.
Other alternative is to copy the images to another folder that you share with AFP and adjust the configuration of netrestore like described in this manual:
http://www.shellharbourd.det.nsw.edu.au/pdf/misc/osxrestoringnet.pdf
This manual was also how I figured out that I forgot to copy the image to the NetBootSP0 folder.

Macintosh transfer over the presets and preferences WITHOUT transferring the ENTIRE HD with "target disc mode

I'm picking up the new 2014 MBP tomorrow so should be installing over the weekend / next week.
I've been currently using a 2011 MBP with OS 10.7.5, using the "home" folder, which I will NOT be doing on the new one MBP with Mavericks.
What is the best way to transfer over the presets and preferences I want, WITHOUT transferring the ENTIRE HD with "target disc mode" or something similar? I am FRESH installing all APPLICATIONS.
Mainly it's the presets and preferences I want to transfer.
Thanks in advance.

Is there a way to keep my Mac Pro On the network without sleeping???

i'll try to explain this the best way I can. I often wish to access my Mac Pro over the network either for file sharing, or for use with Apple Remote Desktop. The problem is after about 20-30 minutes, the Mac Pro sleeps and disappears from the network. Is there a way to keep it on the network without turnig off sleep mode? I really don't want the hard drives working 24/7 if possible....
Thanks in advance!
JPT
P.S. I'm sure it doesn't matter, but just in case..I'm using the new Apple Airport Extreme base station.

In the Energy Saver pane of System Preferences, check the 'Wake for Ethernet network administrator access' checkbox under the Options tab, and then use an application such as this one to send it the signal.

I have created a book in Photo Essay that is extra large (10 by 13") and I just realized that I want a 8 1/2"by 11" book. Can I transfer all the pages to the smaller sized book. If so, how? Thanks so much for your help.

I have created an extra large (10"-13") Photo Essay style iBook in Aperture and just realized that all my other iBooks are 8.5"-11". How can I transfer all the formatted pages to the smaller book size without having to start over? Thanks so much for your help.
Apple Phan

Apple Phan,
that will require some extra work. If you change the book size, some of your edits will probably be lost, because texts and photos that will not fit the smaller layout will be removed. The best you can do will be to save your current book, so you can compare. Try the following:
Create a PDF preview of the current version of the book and save the PDF, see: iPhoto, Aperture: Previewing an order in iPhoto or Aperture
Duplicate the book: File > Duplicate
Then change the Book Sizeof the copy (from the Theme Button) and compare, what is missing, hopefully not to much.

HP Software finds the printer, but then "the printer was unable to be installed over the network"

I have tried to search for a similar issue, but haven't had any success yet. I doubt I'm the first with this problem!
The computer is XP SP3, the printer is Deskjet 3050A, and it's a WPA-PSK WiFi.
The printer confirms that it is connected to the WiFi.
When I run the setup tool on the computer, at the Network Check point, the setup software finds the printer at the correct IP address. It is the only thing it discovers.
I click next, ànd after a minute or two, I get the error "the printer was unable to be installed over the wireless network" Click Retry to try installing the printer over the network again, or click Cancel to return to the connection options.
This just cycles with no progress. I have turned off the Windows Firewall and also disabled the AV. No change.
I can browse to the web interface of the printer - but still can't install the printer. It is listed in the Printers and Faxes as being Offline.
I'll try once again removing it, and re-adding it - but has anyone come across this problem before, please?
This question was solved.
View Solution.

I am having a similar problem as well. The printer is recognized (most of the time) when I run the HP Network DIagnostic Utility. However, when I run the Add a Device setup program to install my wireless printer, it is NEVER recognized. I have even tried to use the advvanced serach to locate it using the IP listed in the Diagnostic Utility without any luck. As an aside, I was able to add the printer through windows just fine and am currently able to print to it, but would really like to add it using the HP installation so that I can configure the "scan to" settings again.
To make matters worse, I no longer have the USB cord that came with the printer because the device has been connected wirelessly for over a year now with minimal issues. Any help getting this brick back online and connected to my network would be much appreciated!

Send BufferedImage over the network

I have already successfully setup a client/server connection. The issue, is when I send the BufferedImage over the network, it says:
"Caused by: java.io.NotSerializableException: java.awt.image.BufferedImage"
Can someone please tell me how to fix this?

Like the exception say, BufferedImage is not serializable. You cannot serialize it. The problem will go away if you don't try to serialize it. Of course, that doesn't answer the question you really meant to ask... which I'll leave for somebody else.

Can object transfer over the network without serialization?
