Problem accessing R/3 with SSO ticket from the EP6.0

Hi all,
I have seen this thread: Problem accessing R/3 with SSO ticket from the EP6.0
I know that it is possible to read SSO ticket from the Cookie in WebDynpro application.
Now we are at the first step, we don't know how to read SSO ticket from the Cookie in WebDynpro application with java code.
So anyone can help us?

Hi,
This has been discussed in a previous forum.Check this link.A code snippet is also there to read a cookie in webdynpro with this question

Accessing a DataSource with a userid, password.

I am getting an SQL Exception with trying to create a database connection using a datasource with userid and password, I can log in to the database manually with the credentials but when I try to access via the datasource this is the error returned.
java.sql.SQLException: java.sql.SQLException: User: doug, failed to be authenticated.
<code>
//-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
// start getConnection
//-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
* Creates a new connection to the database
* @return the connection object
public Connection getConnection() throws Exception{
Context context = new InitialContext();
DataSource dataSource = (DataSource) context.lookup("JDBC-GSFP_ResourceTracker");
return(dataSource.getConnection("doug","root"));
} // end getConnection
</code>
Any Ideas,

Hi
When you created DataSource in Weblogic Admin Console, at one point, you will give all the db details like DB Host, port, sid and username/password. You can TEST the connection also right there. If it says success, thats it.
Now, on the java side, you do Initial context and do JNDI Lookup for that DataSource and directly get the DataSource. There is no need to pass again username/password from Java Side. Just use dataSource.getConnection() without any arguments.
public Connection getConnection() throws Exception{
Context context = new InitialContext();
DataSource dataSource = (DataSource) context.lookup("JDBC-GSFP_ResourceTracker");
return(dataSource.getConnection());
} // end getConnection
Thanks

Problems accessing Yahoo email with Mail on iMac

Hi, I can happily access my emails from Yahoo using my iPhone and iPad. However, neither my MacBook Pro or my iMac (both running Mavericks) can access my emails using "Mail". I can use Webmail on Safari ok, but whenever I try to access Yahoo mail with "Mail", I get a message saying I should re-enter my password, or that the Server is unavailable. I have 2 stage authorisation activated, and "Keychain", and I had to enter a special 'Yahoo-generated' password to allow my iOS units to work. However, each time I use my OSX units, an email says an unauthorised attempt to access my mails has been made.
I've tried deleting the account and reinstalling and rebooting etc, to no avail. I think that Yahoo needs to authorise the iMac and Macbook, but I can't work out how to do it.

Ive found the solution to this problem. Its the secondary sign in system used at Yahoo for unauthorised sign-ins. While its possible to authorise an iPad or iPhone using a special one off password, this cannot be done on a desk top. The simple solution is to switch off the secondary security sign-in option.

Problem accessing SQL Developer with user sys

Hi Experts;
I'm working with Oracle 10G, in Solaris 10, The DB apparently is working properly, but I can not access the DB thru SQL Developer. When I try to acccess with user sys, and I enter de password, in oracle role I select sysdba, when I choose connect I get this error message:
ORA-01017: invalid username/password; logon denied
However, I can connect with other user without any problem.
I was connecting directly in the server, with sqlplus /as sysdba and I changed the password for user sys, but still the problem continues.
What is wrong with this. I got the same problem if try to connect thru OEM.
Thanks and regards
Al

Hi Buntoro;
Thank you for answer.
First, I'm completely sure I'm using the correct password, to be sure I changed the password thru sqlplus.
I'm using tns connection, btw, with the same connection, I can connect, but with other user.
I was trying again, however, with the same results previous explained.
But also I have the same problen when I tried to connect to OEM, and I was trying to stop the dbconsole, and found this:
export ORACLE_SID=YAWIDBLAB
emctl status dbconsole
OC4J Configuration issue. /opt/oracle/102/oc4j/j2ee/OC4J_DBConsole_yawi-db-lab01_YAWIBLAB not found.

Connected.

Apparently, there is problem with the tnsnames. When I see the tnsnames in SQL DEVELOPER I see this: YAWIDBLA
So, here is the tnsname, in order you have a better idea, what I have.
YAWIDBLA =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = yawi-db-lab01)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = YAWIDBLAB)
Is the first time I see this kind of problem.
Have an idea of what's happening;

Problem accessing e.book with the adobe log in details

Hi
I bought an ebook. I downloaded it onto a laptop. I had access t
o it no problems. I had a problem with the laptop and I had to change. I am having a problem opening the same book on the new one it is giving me the following error if I log in my Adobe details The vendor account you entered is not associated with the item you are trying to open. Try again.

Did you register ADE on the old laptop with an Abobe ID?
If so, you just need to register the new laptop with that same Adobe ID.
~~~
If not, you may be a bit stuck.
The Adobe DRM infrastructure has some very undesirable features, and you may have hit one.
When you first run ADE it gives you the option to authorize with an AbodeID, or some other option ('Not Yet'?, I forget exactly how they put it).
That second option effectively authorizes with an 'anonymous' ID which has some very undesirable properties.
ADE does give a tiny bit of warning if you make that choice, but not nearly strong enough.
Any DRM books you buy or borrow get associated with a particular ID when you first process the .acsm and download a DRM .epub file.
After that point it is not possible to change the ID with which the book is associated.
You can copy it between devices (up to 6) associated with the ID and all will go fine, but you can't use it on a device associated with a different ID.
You can change the ID associated with a device (remove the old one, ctrl-shift-D for an ADE computer, ctrl-shift-E for a plugged in eReader device, and associate with a new ID),
but you can't change the ID associated with a book.
An implicit/anonymous ID cannot be associated with any other device, and once an anoymous ID is removed (or lost through loss of device), I do not believe that it is possible to recover that same ID.
Therefore it is not possible to regain access ot the book.
~~~
Your best bet may be to try a DRM stripper such as epubee (google it). Do not then sell or give away the DRM stripped book to anyone else as that is not legal.
I'm not sure if that will work except on a device which has authorization for the ID associated with the book; in which case you may still be stuck.

Problem accessing shared folders with SMB from a Windows machine

When I reboot my Macmini, I cant access the shared folders from any Windows machine. On the Windows machine, I'm being prompted for my password, but event re-entering my password does help to get access.
The workaround I found is to go to the MacOSX System Preferences, Sharing, File Sharing, Options, and to uncheck and re-check the checkbox Share file and folders using SMB (Windows). Then I can access again the shared forders from a Windows machine and I'm not re-prompted for my password.
This is quite trooblesome to do that everytime I reboot my Mac. Is anybody experiencing the same pb? Any idea to fix it?
Also, since Lion, I'm experiencing some connection interruption, especially when copying big files from my Mac to a Windows machine.

Yes that is basically the only workaround for this problem. By chance do you have a SSD installed in the Mini?
I had this problem on my MBP when I had a SSD installed. Problem goes away with the original drive or a Seagate XT series drive.
If you don't have a SSD installed the only other option is to Wipe the drive and reinstall and test (Make a TM backup first so you can restore if the problem continues with the clean Re-Install).

Problem accessing j2ee application in oracle 10g AS

Hi,
I have Oracle 10g AS installed on a Linux 4.0 system. I have deployed an ear file in the AS. The problem is while accessing the application, the login screen is showing, but after submitting it says "Page can not be displayed". The control is not passed to the Action class.
Please help me ...
Santosh

Hi Santosh,
This problem does not sound like an OC4J issue (unless this is a set up issue), it sounds more like your code is not passing the control to your Action class. Please check your struts configuration and make sure your mappings are set up correctly.
Hope this helps.

Problems defining the datasource with coldfusion 9

I just upgraded Macromedia MX7 with coldfusion 9. The local host was http://localhost:8500/ows. I am not sure if this address is the same for coldfusion 9. When I try to define the datasource, I still see Macromedia MX7 instead of coldfusion 9 in administor and I cannot proceed to Login because of the URL "http://127.0.0.1:8500/CFIDE/administrator/index.cfm", and a I get a message "the page cannot be displayed" Please HELP. Thanks, Conabre

It sounds to me like you might have done a parallel install rather than an upgrade?
Is there anything in your filesystem that looks like a CF9 install?
What steps did you follow to perform the upgrade?
If it's just a local machine, it might be quicker to not bother to work out what happened, and just install CF9 and migrate your stuff across to it, rather than doing an inline upgrade. I have to concede I had such poor luck trying to upgrade CF in the past I abandoned it as a practice and always did a deinstall / resinstall rather than an upgrade.

Problems accessing iTunes store with Mac OSX 10.4.11

I am trying to access the iTunes store using Mac OSX 10.4.11 but it tells me to download the new version of iTunes. When I try to do that it says that the new version of iTunes is not supported by 10.4.11. What am I doing wrong? Do I actually need to buy the upgrade from 10.4.11 in order to buy stuff from iTunes again.
Thanks

Try using iTunes 9.2.1.

When attempting to log on to my mobile me account the "loading mail" process does not finish and I am unable to use any features of mobile me. There are no problems accessing mobile me with Safari.

As soon as I enter my user name and password for mobile me the process of "loading mail" begins. It never finishes

We are fellow users here on these user-to-user forums, you're not talking to iTunes Support nor Apple.
Is the credit card registered to exactly the same name and address (including format and spacing etc) that you have on your iTunes account, it was issued by a bank in your country and you are currently in that country ? If it is then you could check with the card issuer to see if it's them that are declining it, and if not then try contacting iTunes support and see if they know why it's being declined : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Account Management
Each time that you add or change your card details then a temporary store holding charge may be applied to check that the card details are correct and valid (though that is usually $1 or the approximate local equivalent) : http://support.apple.com/kb/HT3702
Did your daughter owe any amounts to iTunes ? Does anything show on your purchase history : http://support.apple.com/kb/HT2727 ? If they are proper charges which you don't think that you should have then you can contact iTunes Support via this page : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption

TS3408 Safari on my new iPad mini isn't working - says server stopped responding but no problem accessing the web with my old iPod touch. What's going on?

Safari isn't working on my iPad mini - "server stopped responding" but I can access the web on my old ipodtouch. What's up??

All other apps were working. We fixed it by reverting to factory settings and starting over. Thank you!

Safari doesn't let me access a site with my membership data

I have a problem accessing a website with my account login and password. Everytime I enter my login and password safari prompt me to enter the data again, even though both info are correct (no caps lock, of course), and even if store them in the key chain. I tried with Firefox, Camino and even Shiira. I double checked accessing with a pc and it works.
Here is the error that I get:

if it actually works with those other browsers
try to reset asfari
