Had you paid attention and done your own homework on those previous assignments you'd have known how to do that already.

When starting SAP client always ask about license server

Dear Users,
from few days every user who is loggin into SAP 8.8 PL16 is asking about license server address.
After typing license server address everything works fine until next start of the SAP client - prompt for license server shows again and again.

The same situation - names are resolved propertly. This issue occurs only on that customer installtion from few days.
I have even upgraded 8.8 from PL14 to PL16 believed that it helps, but helped not...

Asking about Content Server web service

                 I have studied Adobe Content Server 4 in evaluation version. I already have finished to setup ACS4 and it
                 can work with sample shop. But now, my company already have own shop for e-commerce purpose. In order to
                 integrate my shop to ACS4, I must use web service to get some information from ACS4 for inventory system.
                 So I have read document many times but still not clear yet. Now I investigate DRM work flow from
                 "Web Service API Inspector" that provide by ACS4. I write own php script for listing all ebook.
                 The following is xml request for listing all book in ACS4 that I copied from "Web Service API Inspector".
                                    http://58.97.41.195:8080/admin/ManageResourceItem
                                    <request action="get" auth="builtin" xmlns="http://ns.adobe.com/adept">
                                      <nonce>RQ4nngAAAAI=</nonce>
                                      <expiration>2010-06-17T09:07:22-00:00</expiration>
                                      <hmac>DP502XxihvqWMDwCezAAVdJBkrA=</hmac>
                                    </request>
                 In the above request I'm very confuse about nonce and hmac value.
                            - What is none created from ? And do you have any sample code to create nonce value
                            - In this case, I understand that hmac is created from the following php function
                                    $request =    '<request action="get" auth="builtin" xmlns="http://ns.adobe.com/adept">' .
                                                       '<nonce>RQ4nngAAAAI=</nonce>' .
                                                       '<expiration>2010-06-17T09:07:22-00:00</expiration>' .
                                                       '</request>';
                                    $key = 'xxxxx' ; // where xxxxx is password for logging in to the ACS4 admin console
                                    hash_hmac('sha1', $request, $key);
                 Am I right ?

Nonce is a contraction of "Number used only once" and is a standard way to prevent message replay. Nonces must be unique until the time specified in expiration. If the nonce is not unique you will get an E_ADEPT_REPLAY error message.
The signature element is the hmac of a particular infoset serialization of the xml. For examples of this in Java see the sample code for UploadTest et al. If you ask support, they can provide sample serialization in php. Hashing the raw bytes of the message as you did is not correct.
An alternative for your development is to turn off authentication by adding the following line into your admin config file:
com.adobe.adept.persist.skipAuthentication=true
The signature element will still be required, but it doesn't matter what the value is other than it being valid base64 encoding, so you could just use aaaa for example.
However if you do turn off authentication then it is up to you make sure the admin service is secure (by restricting access through vpn/firewall rules or whatever other means you choose)

Asking about how server can handle client disconnection

Dear sir/madam,
i'm doing my final year project and it is about a java client/server big2 game.But now i have a difficulties in dealing with the server side.
That is about how to take action on the serverside if the client suddenly disconnected.
I have read many java client/server programming scripts.But all of them doesn't mention this problem.The scrpits only assume the client side never disconnect suddenly.
I hope if you can give me some suggestions on this problem.

For my mud written in java, I used TCP/IP for the connections. When a client connects, he gets his own thread. Those threads are held in a vector in a manager class. each tick of the server does a quick run thru the vector and if the current thread/socket its on is null or !isAlive() its remove from the vector(which in turn removes it from getting any more game updates. This removal can be caused by two things. The clients disconnects by accident(kills his game, locks up has an internet connection hiccup, etc.) or he uses the games "quit" method. The quit method calls a method that does any player saving of data, etc then closes the socket, and sets it to null. thus the manager sees this and removes him frm the vecotr list on the next server tick. Seems to work great form a mud and worked really well in a multiplayer applet game I had up for a while.

Excuse me, but I don't understand How I can contact a ADOBE expert to ask about my problem? I don't found a mail, or chat or other else...is it possible? Only help for Customer is on the Forum?!?!?

While it is possible you have a faulty unit I'd agree that the menu system took a step backwards with the itunes store centric take 2.0+ software. I think I'm in the minority here though. Apart from the 2.0+ top level interface being butt ugly and confusing to navigate, it simply isn't as responsive as 1.0/1.1 and I think most of this is to do with displaying a combined sync/stream menu. if you sync stuff try setting 'show only synced items' in the AppleTv device tabs in iTunes and see if it makes the issue go away - easy to revert back.
Huge libraries (number of files not actual size of the files) can also be problematic given AppleTV's modest hardware specs but that's more exception than the rule.
With streaming/syncing combined I also think any network deficiencies show up more than they used to.

Trying to produce a java chat server

Would like produce a working client/server chat system, as basic as possible but able to listen and talk to each other. Any chat servers how-to examples I've come across never seem to work.
Would like to understand why applets don't work when I open the web page but do work when I view using the appletviewer. I use Internet Explorer 4 i think, java version 1.3.0_02
would you understand at least part of this error which appears when I run a chat server

(the error is all one line no spaces)
the following code is one of the programs I've been working on and I receive the above error, appletviewer doesn't work so i think that means something is wrong with the code, client side as the server side works well, it listens etc

Need info about RH Server 6 and reports

I'm interisted in RH Server 6 but I'm unable to locate much
practical info about it on the Web site, and a call to sales didn't
help. I need to know what I'm getting us into before I contribute
our $2,000. Can anyone provide this information or point me to its
location on the site:
--I have system requirements from the Adobe site, but what is
the "server" and what does installation and setup entail? About how
how long does it take, or how difficult, to achieve operability?
--According to a piece by John Daigle, the server component
should be installed on a Windows server running IIS 5+. Is IIS a
separate software or standart part of Windows server? If separate,
what preparation should that server have before the installation in
addition to installation of IIS?
--I know nothing about security/firewall protocols. We will
have our own and our customer firewalls to navigate. Are the server
setup instructions adequate for setting all that up? Or are
purchasers expected to have sys admins knowledgeable to set that
up? Is that applied to the RH server or the Windows server? if RH
server, how can I get a copy of instructions for my system people
to review?
--Have users found the RH server/RoboEngine reliable, once
it's operable?
--Is it true that the usage reports aren't customizable? Can
additional usage data be specified in the RH server?
--These report summaries are vague--Areas Requiing Help,
Frequently Viewed Content--stating only that repoorts show the
suchandsuch done "most frequently" or "most often." Does that mean
the top 3, 5, 10 or what? Is there a way to track all of that
activity from most to least?
--The summaries of the reports Unanswered Questions and
Frequently Asked Questions say that terms entered in the Search
field are identified. Questions and terms aren't the same in my
book--am I right that it captures anything entered? Can it do the
same for the Index field?
--I saw no RH server under downloads, or maybe missed it.
Correct in guessing that a demo version is not available?
--Is RH server user doc available on the web site? I found
the Getting Started gude, which isn't much use in evaluating the
product.
I have additional questions, but if you can answer these
questions or direct me to answers some of those may be covered.
Thanks,
Mike
Access database.

Hey, Mike!
I found a few things for you. I'm in a hurry, so I'll list
them quickly.
For the Trial, go to the Adobe downloads page
http://www.adobe.com/downloads/
Then select RoboHelp Server 6 from the dropdown list. You
will be asked to register (free) if you haven't already. When you
arrive at the download page make sure you note the Trial Serial #
To make it easier for you, its:
1336-1033-2628-5062-0993-4570
You can also find a RoboHelp Server 6 Getting Started Guide
here
http://www.adobe.com/support/robohelp/downloads/getting_started_rh6_server.pdf
You were asking about IIS. Yes. As Colum says, this comes
with virtually any version of Windows Server (or Windows XP
Professional). However, you must install and configure it. I am not
an IT or web administrator so it took me a while to learn, but
amazingly I got it to work if you're patient and follow the steps.
(I'm speaking of both IIS and Robohelp Server) Clearly IIS
configuration is not a trivial thing and it is assumed that an
author would have help and cooperation from the IT or Web Admin
folks.
As for customizing reports. At present, the existing reports
are the only ones offered. Since these reports are generated from a
database (Access, SQL Server or Oracle) I would think (haven't done
it myself) that someone familiar with database adminstration could
open the DB (after a backup that is) and be more creative with
generating customized reports.
You are right that the "Question" does in fact mean any
search term or phrase that an end user puts in the search field.
This is the string that is stored and reported as a question. In
discussing this with the Adobe team at STC last month, they agreed
that this was definitely a holdover from the legacy software and is
due for a change sometime in the future.
To answer your other question, text entered in the Index
field is not stored in the database, only the search term field.
Since taking on the old legacy product from eHelp and
Macromedia, Adobe is focusing most of its attention on beefing up
the client authoring app for the next version (Adobe RoboHelp 7).
My assumption is that they are keen on improving the RoboHelp
Server as well. I have passed along many feature requests along the
lines you seem to suggest and hopefully the server will evolve
along with the client app.
Even with its limitations, my clients tell me RoboHelp Server
provides very useful feedback to help them improve their knowledge
base content to make it more helpful and responsive to users needs.
They also like the searchability of PDF, Word, PPT and Excel as
well...something which plain WebHelp without the RoboHelp Server
does not do.
I probably didn't get to everything, but hope this helps.

HT4913 Trying to add new macbook air to itunes match. process starts but never succeeds. works for a while then give error about itunes server.

Trying to add my new Macbook Air to iTunes match. Process starts but goes nowhere. After some time I get error about iTunes server losing connection. Help! I want to access all my music.

Hi Rob- I'm guessing it has something to do with all the update stuff Apple keeps doing (with Yosemite, etc.,) extremely frustrating - also whenever I load up iTunes on any of my devices- I am asked to enter my passcode- which I will do- then I am asked to do it 2 or 3 more times - right after the other- crazy how annoying something like that can be- I have looked online for solutions- i.e. close out of the account, reset the passcode- all of it- nothing seems to fix that situation either- what I have discovered (playing around) is on my iPhone 6+ if I go to settings and turn OFF iTunes match- then turn it back ON- suddenly all the music that wasn't loaded shows up magically- but I had to do that each time I'd update songs in my playlist on the iMac- then go to the iPhone and turn off the match- then turn it back on- almost like it is resetting things-

Need some help on JAVA CHAT SERVER

High availability for Lync 2013 persistent chat server and office web app server

I have 1500 users, need HA in primary data center and DR also. looking for HA and DR solution for persistent chat server and office web app server.
is below correct?
1. 2 persistent chat server in a pool of primary data center and 1 in DR. can this be reduced or any changes?
2. 2 Office web app server in a pool of primary data center and 1 in DR. can this be reduced or any changes?
also do i need HLB for both roles?

1) In Lync Server 2013, there are improvements in both high availability and disaster recovery:
High availability improvements: SQL Server mirroring is used to provide high availability for the Persistent Chat Server content database and Persistent Chat compliance database within a data center (in-site).
Disaster recovery improvements: Persistent Chat Server supports a stretched pool architecture that enables a single Persistent Chat Server pool to be stretched across two sites (that is, a single logical pool in the topology, with servers in the pool physically
located across two sites). SQL Server Log Shipping is used for cross-site disaster recovery.
For more information about high availability and disaster recovery, see
Configuring Persistent Chat Server for High Availability and Disaster Recovery in the Deployment documentation.
2) for HA & DR, you can 2 Office web app server in a pool of primary data center and 1 in DR. and You will need HLB for office web app servers

I have few questions to ask about the Expert Series and Valet Series

Hello.
I have few questions to ask about the Expert Series and Valet Series.
1. I see there aren't any print server/bridge/access point for these two new series. Do I have to use previous ones? Or the new ones are in planned in near future?
2. Do I "HAVE TO USE CONNECT SOFTWARE"? Can I just use web interface to do every setting that these routers features?
3. Does expert series routers support guest network and parental control?
4. When I look into informations of these router, some router doesn't give information about backward compatible to older standards. Do I have to consider that as they are backward compatible with older standards?
Ok, that's all for now.
If I need to ask more questions I will do that in this thread as reply

With the New Expert or the Valet Series Router, you still can use the Print Server / Bridge and Access Points.
Well with the Expert and Valet Series router, you have an option to User Cisco Connect Software or you can User Web Interface of the Router. But with the Cisco Connect Software you have an Advantage of creating a Guest Account and using Parental Control , which is not available using the Web Interface.
These both the routers are backward compatible and they can connect to your G Series Product.

I run OSX10.6.8. Just dwnlded FF8.1 and everytime I go to open it I am asked about the disk image. But if I delete the dmg, the program won't run.

I just downloaded the 8.1 version. It was a 30+mb file. Previously I ran 4.0. So I drag the new Firefox icon into the Apps folder. It does its merge thing with the old version. Problem is when I click to open FF now, it always throws up this window asking me about the disk image of what I just downloaded. I even tried restarting the computer--but the same message pops up. I checked on your website and it says that I need to "eject" the disk image (i.e. I'm guessing that means the 30+ mb file I just down loaded), so since I don't have an eject option that I can find (except for external harddrives and cd/dvd), I just drug it into the trash. I go to empty the trash and I get a message that that dmg file is "in use" even though FF is completely shut down. So again I'm guessing that means that even though I already merged that dmg file with the old 4.0 version file, if I dump the update file it seems that it's going to mess up the actual revised program file still remaining. I just want to be able to click on the icon in my dock like I've always done and have FF open. I don't want to keep being asked about disk image stuff. Somehow this feels like an easy resolution, but I just can't seem to put my finger on how to resolve it. Thanks for you help.

Nope---didn't work. I've owned Macs for about 12 years so although I am brain dead on some things, I do have a working knowledge on most things. I only say that to say this--I did try holding down the mouse and choosing empty trash. It asks if I want to permanently delete what's in there. I say yes--and then I get the same identical message again-----'The operation can't be completed because the item "Firefox 8.0.1.dmg" is in use I can then click stop, or continue.' So apparently that complains the same way it does if I click it up on the menu :)))
As for item owned by---that's not an issue and isn't coming up. User is not a problem either as I am the only user on this system. There is only ONE file in my trash at the moment at that is this dmg file. Nothing Mac. Nothing owned by anyone other than Firefox. The problem seems to be that the dmg file and the original 4.0 FF file are working in tandem with each other--even though I have already drug the new 8.0 globe into the Apps folder and it updated the FF app with the new stuff. If I could force the dmg file to go away, I would do so, but at every turn the system is telling me it can't be done because it seems to think that dmg file is in use---even though everything is shut down and/or ejected. Hey--I'm getting ready to head out and won't be back till evening. I'll check back in this evening. Thank you again for your help.

Hi, I asked about my WiFi modem? Sorry but I don't understand any of the suggestions given to me. We don't have an Apple Store where I live, the rest of it's over my head. I also don't own a PC. Any other suggestions? What's IPS?

What I want to know is why did my WiFi modem work just fine for a whole week, now it doesn't. I can't get any Internet access if it's connected, if it's not I can't download apps from AppStore,as I have no Internet access. I'm tech literate, I don't understand what an IPS is, I don't know about ports and numbers, and there is no Apple store where I live. So now what am I supposed to do? My mum bought me the **** thing, it cost her $150, and it's worked for a week, and then excuse my French, **** itself! Can someone please help me, and in English please? I've only had an iPad since Christmas, I don't have a PC and wouldn't know how to do any of that stuff if I did. Very Frusterating!

You asked about IPS. I believe you mean ISP, or your Internet Service Provider.
Since you don't have a computer, you won't be able to change the router settings.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.

I have an iMac model 4,1 running OSX 10.6.8.   The CD/DVD drive went bad and I have replaced it. However I can not get disks to eject.   I have asked about this before and tried all all the suggestions I have received but I can not eject.

I have an iMac model 4,1 running OSX 10.6.8.   The CD/DVD drive went bad and I have replaced it. However I can not get disks to eject.   I have asked about this before and tried all all the suggestions I have received but I can not eject.
Yesterday I opened up the iMac and reinstalled the drive to make sure that it was not an alignment problem.   I still can not eject.   When I try to eject the drive makes noises like it is ejecting but the disk does not come out.
How do I solve this problem?

Hi again Hal
Link to your other thread > The slot loading CD/DVD drive in my...: Apple Support Communities
You have also tried resetting the PRAM as I suggestion in your other thread...?
See resetting the PRAM > About NVRAM and PRAM
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
