Connection exception not delivered on the server side

          I have written a standalone java program that acts as a JMS client using asyn listener
          to receive the message from a jms server. Inside the program, I have set a connection
          exception listener that will do a re-connection whenever the onException() method
          is called. This works fine and JMSException is delivered whenever the weblogic
          server hosting the jms service crashes. However, when I port this program into
          a different weblogic server, i.e. wrapping it inside a servlet init() method.
          The JMSException is no longer delivered when the weblogic server that is hosting
          the jms service crashes. Is it normal?

Just escalate internally.

Error getting the server-side naming service functionality

Hi all,
we are currently setting up the CTS+ activity based transport scenario. Everything seems to be working fine, however, we have to import each transport twice...
Before I go into detail in the error we get I will first describe our landscape. All the configuration we did was done in debate with SAP.
We use the SAP Solution manager (ehp1 SP 4) as the CTS+ server as recommended by SAP and have an NWDI system of which we only use the components DTR and CBS (since CMS is not used anymore in the activity based transport). We have defined three logical ports/RFCs. CTSCONFIG points to the NWDI system. CTSDEPLOY is running on the java stack of the solution manager and is only used for portal content (=epa) transports. CTSDEPLOY_DI is pointing to the NWDI system and is used for all NWDI (=dip) changes. The NWDI is running ehp1 SP3.
In STMS I defined all the non-abap systems (and configured them to use CTSDEPLOY_DI) and created the following transport route:
upload system (IMP) -> DEV -> ACC -> QAS -> PRD
I first attached the used dependencies in a transport request (SAP_BUILDT, EP_BUILDT, etc) these imported just fine. Then I did the SCA files which contain our custom code. I extracted these from the assemble step on our current NWDI system which will be removed as soon as we switch to the new CTS+ environment.
When we import the transport into the runtime systems then we see the DTR and CBS be filled sucesfully for this specific system. However, the transport request itself always fails with errorcode 12 and the error is:
Error during export service registration: Error getting the server-side naming service functionality during getInitialContext opera
tion. com.sap.engine.services.jndi.persistent.exceptions.NamingException: Error getting the server-side naming service functionality during getInitialContext operation.
Error in execution of Web services CTSDEPLOY_DI , exception is cx_cts_file_import_failed
File import canceled
When we then reimport the same transport it will go the second time fine. This is no problem during the setup but will not be workable when we go live ofcourse. Is there anyone who had this issue before as well and have a solution for it?
Kind Regards,
Nico van der Linden...

Hello Nico,
I would need the java trace files to get more info on this issue, but you can start troubleshooting this error with these notes:
#1172252: CTS+, 'attach file': Troubleshooting Guide;
#1003674: Enhancement for non-ABAP systems in CTS;
#1155884: CTS+, configuration 'close coupling': Troubleshooting guide;
Pay special attention to parameter NON_ABAP_WBO_CLIENT, whether it's correctly set on your CTS+ system(s).
Note #1003674 is a must for any CTS+ systems to work properly, as well as having an updated version of the transport programs (tp and R3trans).
Lastly, note #1155884 goes through some JCoException exceptions that commonly take place during CTS+ transports. But again, you need to check the underlying trace files to find the root cause of your issue.
I hope this information helps.
Best regards,
Tomas Black

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.

Catch(Exception exception)
Given Below is the Error.. The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.
Solution:
The error might occur due to following cases.
case 1: when the password is wrong
case 2: when you try to login from some App
case 3: when you try to login from the domain other than your time zone/domain/computer (This
is the case in most of scenarios when sending mail from code)
There is a solution for each
solution for case 1: Enter the correct password.
Recomended: solution for case 2: go to
security settings at the following link https://www.google.com/settings/security/lesssecureapps and
enable less secure apps . So that you will be able to login from all apps.
solution 1 for case 3: (This might be helpful) you need to review the activity. but reviewing the activity will not be helpful due to latest security
standards the link will not be useful. So try the below case.
solution 2 for case 3: If you have hosted your code somewhere on production server and if you have access to the production server, than take remote
desktop connection to the production server and try to login once from the browser of the production server. This will add exception for login to google and you will be allowed to login from code.
But what if you don't have access to the production server. try
the solution 3
solution 3 for case 3: You have to enable
login from other timezone / ip for your google account.
to do this follow the link https://g.co/allowaccess and
allow access by clicking the continue button.
And that's it. Here you go. Now you will be able to login from any of the computer and by any means of app to your google account.

Why the server side behavior of LoadVars() not consistent?

In my server side script for FMS app,there is such code:
var lv = new LoadVars();
var params = new LoadVars();
lv.send("http://mysite.com/registerVideo.php", params, "POST");
The expected behavior is that the request will be as if sent directly from the browser,thus SESSION information is not lost ,which is the exact behavior for my computer.
But it's not the case for my boss --- session information is lost for him.
Why the server side behavior of LoadVars() not consistent?
What do I need to do to make sure session information is not lost @ server side ?

Oops,why this feature has always worked like charm for me only??

There was a problem connecting to the server "Time Capsule". The share does not exist on the server. Please check the share name, and then try again.

The following error pop's up as an [OK] dialogue box after logging in the iMac,
There was a problem connecting to the server "Time Capsule".
The share does not exist on the server. Please check the share name, and then try again."
As it happens, a connection to the Time Capsule is established usually, anyway. On occasion it doesn't.
I have a Volume, Data, on the capsule, which similarly, usually mounts, but occassionally doesn't, with access permissions denied.
Any suggestions on how begin to work out how to achieve networking seamlesness?

First, restart the Time Capsule by disconnecting the power adapter and reconnecting it. If other devices on the network can see it, you can skip this step.
From the menu bar, select
 ▹ System Preferences ▹ Network
Click the lock icon in the lower left corner of the window and authenticate to unlock the settings, if necessary. Click the Advanced button, then select the TCP/IP tab in the sheet that drops down. Click Renew DHCP lease.
Try again to back up.
If you still can't, open the Time Machine preference pane and delete the TC from the list of backup destinations. You may have to unlock the settings by clicking the lock icon in order to do this. Then add it back.

Actiance Vantage server duplicates the IM details and both Active Active Vantage servers connection is not established at the same time

Hello
Issue with the Actiance Vantage server.
Env: Lync 2010 Server , Vatage servers - 2 active , 1 passive
Commn: FE contacts HLB to reach Vantage servers
Recently we have added one vantage servers to the lync environment and made two vantage servers as Active.
After adding 3rd vantage servers and made two vantage servers as active , we are seeing the following behaviours:
1) archived messages are duplicated with different transcripts ID
2) Two active servers connections were not established at the same time. Only one is active at all times. There is four front end servers.
Request for suggestions.

Hi,
Did you receive any error message?
Please disable the third Vantage server and test again.
Please check if all services started for all FE servers and Vantage servers.
You can enable logging on FE servers for further troubleshooting.

Can I close the connection after sending immediately on the server?

I have a C/S program. On the server side, the process as following:
1. accept (blocking)
2. //a connection is established
using a new socket to receive request data from client
3. business processing ... (maybe several seconds)
4. send response data to client
5. close socket immediately
6. listening continuely again
The server side is running on linux and writed by Java, and client is running on windows and writed by C++ Builder.
My problem is:
1. if the server is running on windows, everything is OK.
2. if the server is running on linux (that is exprcted), the client can not receive the response data from server, the client program said the connection is unavailable when he read from socket blockingly.
3. if I add some delay, e.g. 500ms, between sending response and close the connection, the client can receive response normally.
why above?
thanks for help.

If I uncomment "Thread.sleep(500);", it means wait some time before close socket, the client can receive all response data.
why?

Where is the photo tab on itunes? My device is not listed on the left side of my screen and there is no photos tab on the right of my screen. I want to delete photo albums that were synced through itunes to my ipad 3.

I synced several photo albums to my iPad 3 from my computer through iTunes. Now, I would like to remove them and have discovered that they cannot be removed except through using iTunes. Instructions that I've read say that once the device is connected to and selected from the list in iTunes, select the Photo Tab and then the folder that contains the photos etc. I never get that far because I do not have a Photo Tab to select in iTunes. How do I find this illusive tab so that I can delete these albums that are merely duplications of other pictures and are just occupying space. I need to get rid of them. Can anyone help me find the photo tab. I cannot move past that step until I do. Also, my device is not listed on the left side as stated in the instructions. It's in the bar on the upper right area of my screen and is automatically selected when connected. I am using the current version 11.1 for iTunes and IOS 7 on my iPad 3, if that helps.

I have the same problem on the latest iTunes software and Windows 7. My window is maximzed and I do not see any tab for photos. Seems related to a recent update (IOS7?) as this was there - at least before the very big change to the interface.

Since upgrading to Yosemite I am getting frequently "safari can't open the page (blank) because the server unexpectedly dropped the connection this sometimes occurs when the server is busy. wait and then try again"

Since upgrading to Yosemite on my iMac I am frequently getting "safari can't open the page (blank) because the server unexpectedly dropped the connection this sometimes occurs when the server is busy. wait and then try again". This is with both a WiFi and Ethernet connection. The server is working fine from other devices using WiFi onto it such as iPhones, iPads, MacBook (which is also on Yosemite) so don't believe its an issue with the server.
I am also noticing page load very slowly when this problem is not occurring.

Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Needs a background webdynpro application running at the server side

Hi All,
We have a requirement wherein we need to have an application running all the time at the server side to capture the response coming from a web application. Based on the response that the application receives, it needs to update some backend R/3 tables.
We are thinking of a webdynpro java application.
Can anyone suggest what kind of application needs to be implemented here?
And what would be the steps required to run the application at the server side without calling the application.
Thanks & Regards,
Anurag

Hi Robin,
Thanks for the detailed explaination.
This may sound silly to you but I've another doubt which is as follows:
As you mentioned that the external web application will be sending requests to our Web service(in SOAP envelopes) and rest of the functionality can be achieved by our web service.
Actually, we are expecting only responses from the external web application. The thing is that we are sending the requests to the external web applications from our custom webdynpro application and in return the web application will be sending us 2 responses.
First response would be back to our WD java application URL(to the browser in which WD java app is running) which would get the response and display some message based on the response.
Second would be to this web service which you have just suggested. We are having two responses so that even if the browser in which the WD java application is running gets accidentally closed, the response from the external web application must get captured somewhere else and should not get lost in any case.
So, now since we are only expecting the response from the web application and we do not want any requests from the web application to our web service; how is this possible?
I am asking the above question because you have mentioned that the external web application has to request our Web service but we want is only this web service to capture the response coming from the Web application.
Or is it like the web application will send us the response string as request string to our Web Service and the web service will capture these response parameters as request parameters from the web application and do the further processing.
But in that case, we do not want any response to be sent by the Web Service to the external web application.
Please suggest if this is possible.
Once again, many thanks for the help so far.
Thanks & Regards,
Anurag

I bought a new imac running Loin and Office 2011. The server we use to access emails runs exchange 2003 and my IT person says the imac is not compatible with the server. The server does not want to let me access using any email software.

I bought a new imac running Loin with Office 2011. I am the only mac in the office and the Server we use to access emails runs exchange 2003 and my IT person says the imac is not compatible with the server. The server does not want to let me access using any email software other than webmail access through our website. It looks as though 2011 is not compatible with 2003 per some searches online, but what are some options I have to gain full access again? I purchased parallels in hopes that this my help and I am able to use remote desktop connection to log on to server but can not drag and drop files I need. There is a shared drive on that Server we all use to exchange files.
The two main issues are gaining access to my email again and ability to drag and drop files from mac to pc. I hope this is enough info to get some solutions.
PS - IT person says my iMac's IP is what his server does not understand so that is why I can not login.

Office 2011 is not compatbile with Exchange 2003.
I suggest you post further Office related questions on Microsoft's own forums for their Mac software:

How can I disable excel addin on the Server side?

Hi, is there any way to disable excel addin on the server side?
We want to disable it so that no one can modify or read data in the cube in the production environment, even if he or she had installed the add in. Instead, we provide the Planning data forms as the only interface for end-users to read and write. we do this because the add in is very easy to install and users can read and write data in the cube at their will.
As we designed to keep the security filters simple, it is not a good idea to controll data access through security filters.
so, what i'm asking is how to disable excel addin on the server side?
Thank you for replying.

Hi,
As Gurus suggested, you will have to restrict viewing of data through dimension level security.
Give access of members to users, only which are relevant to users so that they can't view other user's data/members.
Like give access of members belonging to HR dept only to HR users and give access of Finance dept related members to finance users only.
Hence HR users will view only HR relevant data and won't be able to view (read or write) finance related data and vice-sa-versa.
Hope this helps
Regards
-SM

How to delete the server side sessions

Hi All,
I have a wireless application and it is accessed through ptg/rm gateway from a PDA browser. Oracle wireless AS gives default login page (when the application is accessed through ptg/rm gateway) and when user login, user information session might get stored in server side (I am not sure, if any one can pls clarify me on this also?).
Now i have a requirement, in which my application user should get 'logoff' button in each and every page of my application. When he clicks on this button the user information session should get invalidated, so that even if the user goes back to the application (using back button of the browser) he should not able to enter the application. (This is same as any std. login/logout page logic).
Invalidating the session which resides in client side is easy (By using session.invalide()), but how can i delete the session which resides on the server side??? Whether is it possible??
If yes then how can i do it.
Any help will be very usefull.
Thanks well in adavance.
Shrikant

Shrikant:
Shouldn't it be easy to invalidate the server sided sessions? Right before invalidating the client side session, send a message to the server, which should call its session.invalidate() after it has obtained the current session. If desired, a message can be sent back to the browser informing user that server side session has been deleted.

How to check if a socket is still alive and not closed by the server?

If I create a socket connection in Java, then is there any way to test whether that socket conecction is alive at any point of time. You may assume that the socket connection is never closed from my side ie. the client's end, however it may be closed by the server at any time.

The only way to tell if the socket has been disconnected is to send data over it.
set the timeout on the server side socket and then have the client check in every so often within the timeout so if you set the client to check in every 10 seconds then set the timeout to say 30 seconds on the server socket.
if the server socket times out then you know the connection has been broken.
