How to get an session BackingBean out of the FacesContext

Hi,
I want to make my appliction userdependent (each user only see's his own data).
There fore I created a UserBackingBean with a session scope.
An attribute of my other backingbeans is the User object. In my UserBackingBean I want to create a static method that returns the current user. Only I don't know how to get the UserBackingBean from a FacesContext.
Please help?
Romano

... and if you decide there MAY be several users logged in simultaneously, you can get the user associated with the current session by doing :
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
Map sessionMap = externalContext.getSessionMap();
UserBackingBean userBackingBean = (UserBackingBean)sessionMap.get("userBackingBean");assuming you labeled your UserBackingBean managed bean "userBackingBean" in your faces-config.xml

Hi
The session time out value for CRM WEBUI is controled by parameter RDISP/PLUGIN_AUTO_LOGOUT.
Its value is got by BSP.
Please check in SE80 BSP application CRMCMP_IC_FRAME view hideenview.htm.
If you want to know the session time out value for portal, I am afraid that you need to raise questions in EP's forum.

How to get a Connection Matrix out of the FireSight?

Hi All,
did someone have a useful hint how i can get a usefull connection matrix out of the FireSight Management to create a Ruleset for the ASA, which is at the moment on pemit any .... Focus should be a list of source and destination IP with port and maybe a counter - did some investigation on the connection events - but it is too much information and too much same events - and i have only events from the last 2 days ... i would like to get the result maybe from one or two weeks - is there a way to do this?
Thank You in advance
Helmut

You can generate reports based on connection events and connection workflows. You could create a custom workflow with something like Initiator IP, Responder, IP, dst port, count. That would give you the count of connections between a src/dst IP on a given dst port.
As for connection history that's a tough one depending on the amount of traffic going through your device. The default connection limit is 1M connections. You can raise that in the System Policy database setting but be careful as bumping this up too high can cause it to take a long time to process connection event queries. A week is really all we can ever hope for and even that is often too long (too many connections).

How to get a mini disc out of the drive?

Hi all. I have just made the stupid mistake of putting a mini disc inside my G4 and i cant get it out by ejecting. It is not even detected by the system. People have recomended restarting the system and holding down the mouse button, but that did not help. Others have recomended sliding a business card into the slot, however I'm reluctant to try that due to fear of damaging my system. Is there any safe way to professionally remove this disc? Any help is much appreciated.

The absolute safe pro way is to pull the drive and open the top. Sorry a pain I know.
There are other ways, some more dangerous than others

I bought an iphone of my friend and used my blackberry sim in it, it say i have signal on 3g but imessage and twitter does not work when not connected to wifi, and i dont know how to get it to work out of the house?

The phone is not stolen but it does not work out side of the house

if it doesnt match that means your iPhone is not provisioned for the carrier you are trying to use. Your iPhone would need to be unlocked in order to use on other carriers. You will need to contact your carrier to see if this iPhone is unlocked py providing them the IMEI. If the iPhone is not unlocked you will need to contact the carrier that the iPhone is locked to to see if they will unlock the device to use on another carrier.

HOW TO GET A REVERSED RECEIPT OUT OF THE AVAILABLE FOR RECONCILIATION

Hi All,
We have reversed 3 receipts in Ar as it gave error while posting. Now we are getting these entries in Bank reconciliation report.
Please suggest.
Thanks in Advance,
Ajit

Hello Ajit,
Remember there are different types of Receipt Reversal. The two you're probably interested in are:
Reverse Payment; and
Non-sufficient Funds
You would use 'Non-sufficient Funds' in situations where both a credit and debit appear on the bank statement - e.g. A customer cheque that bouces due to insufficient funds. This will be available for reconciliation to a bank statement debit item.
You would use 'Reverse Payment' when the original receipt was entered in error. This will not be available for reconciliation to a bank statement debit item.
If you have reconciled a credit to a receipt which you later realise was entered in error it is important that you unreconcile the credit before reversing the receipt with 'Reverse Payment' (as the money has been incorrectly reconciled - and you'll be left with an accounting headache if you don't).

{code}Sure, if you have other data that you haven't mentioned yet, then you need other columns, and maybe even other tables, to store that data.
Talking about this would be a lot easier if you described what you were trying to model in these tables, and what the different entities are.

{code}What do checkseq and checkdate represent? What is the realtionship between them? If there is another row with checkseq=3, will it necessarily have checkdate=01/01/2011? If there is another row with checkdate=01/01/2011, will it necessarily have checkseq=3?
Shouldn't I need to have the extra seq(PK), then use check seq to group the data report to meet users' target format ? Please adviseIt depends on what your entities are. If you explain that, then perhaps I can give some advice about how to model them.
In general, every type of entity requires a separate table. It looks like xcert represents one kind of entity, uniquely identified by certno. I assume there is some other kind of entity, uniquely identified by checkno, and that you have a table for that which you haven't needed to show in this thread.
Are you saying that there's some other entity, that is uniquely identified by checkseq? If so, it probably needs a table of it's own.
Every table should have a primary key. I had assumed that checkseq only served as the primary key of the xcheck table. If it serves some other purpose, then yes, you would need another column.
Many-to-many relationships usually require a separate table. I was guessing that xcheck was intended to record a many-to-many realtionship between xcert and some other table. Guessing is not always the best way to solve problems. I think it would be better if you explained what you want to do, rather than have me guess at it.
So far, what you've shown is analagous to an order entry system. One kind of entity is customer, another is supplier. Say you're running a company that sells products from many suppliers to many customers. There is a many-to-many relationship between customers and suppliers. Any customer may buy from many suppliers; any supllier may sell to many cutomers. You may have an orders table that keeps track of that many-to-many relationship. You may also have another entity, salesman, that also has many-to-many relationships with customers and suppliers. Depending on what exactly you consider an "order", there are lots of different ways to model this. Can a single order involve many customers? Can a single order involve many suppliers? Can a single order involve many salesmen? If an order always involves one customer buying from one supplier using one salesman, then you may only need four tables. If the situation is more complicated, then you may need more tables.

How to get transacted session in direct mode with jmsra adapter

Hi,
I use MQ 4.4u1 release with GF in EMBEDDED mode. I configured several connection factories with NoTransaction/LocalTransaction/XATransaction support. In my app I get a connection factory from JNDI tree, create connection/session/producer and send several messages to queue. Everything works fine when I don't use transactions. But, when I want to send messages in one transaction, the connection always provided to me non-transacted session. The session created via
Session session = connection.createSession(true, Session.SESSION_TRANSACTED);
request. I check the session transacted state and acknowledge mode right after i get it:
log.fine("Session: " + session + "; transacted: " + session.getTransacted() + "; ackMode: " + session.getAcknowledgeMode());
The log shows me that the session is not transacted and ackMode is 0 (DUPS_OK_ACKNOWLEDGE). If I try to commit the session after messages were sent I get the correct exception:
javax.jms.IllegalStateException: MQJMSRA_DS4001: commit():Illegal for a non-transacted Session:sessionId=3361979872663370240
Does anyone know how to get transactional session in direct mode?
Thanks, Denis.

I mentioned LOCAL because I misread your post and thought you were suggesting that LOCAL mode behaved differently.
If you want to send messages in a transaction from within a Servlet then I think you're expected to use a UserTransaction: Here's an example that worked for me:
        Connection connection = outboundConnectionFactory.createConnection();
        Session session = connection.createSession(true, Session.SESSION_TRANSACTED);
        userTransaction.begin();
        MessageProducer producer = session.createProducer(outboundQueue);
        int numberOfMessages = 10;
        for (int i = 0; i<numberOfMessages; i++) {
            Message message = session.createTextMessage("Hello world");
            producer.send(message);
        userTransaction.commit();
        connection.close();I obtained the UserTransaction with this resource declaration:
    @Resource(name = "java:comp/UserTransaction")
    private UserTransaction userTransaction;The EJB spec explicitly states that local transactions aren't supported in EJBs; I haven't found such an explicit statement for Servlets but suspect that JMSRA is taking the same approach.
As for imq.jmsra.direct.disableCM property - this appears to disable connection pooling and from your post changes other behaviour as well. How did you find out about it (other than by examining the code)? As far as I can see this is not a documented feature and is not necessarily tested or supported.
