About EntityManager and queries

Hi. I'm just getting started with EJB 3 and JSF. I have noticed that, in our session beans when we want to make a query, we use an EntityManager, which invokes a method which I think is createQuery. This method returns a Collection of Entity objects, but I have noticed that our queries are set like "from EntityBean where...", which means that I can't find any "SELECT"!!!. Is this normal? Is there any way that I can use a normal query, such as "SELECT Name from Table WHERE..."? I hope that I can get some help, thanks in advance!

You do not need to explicitly destroy anything unless threads
are spawned in a non standard way by Java or C code that you are

A question about objects and queries

I just started using COM objects in ColdFusion. I am mostly
using CreateObject, but occasionaly use <CFOBJECT>
My question is; Do I have to destroy these object variables
when I am done? I know in a lot of other languages I work in, you
have to "clean up'" after yourself and destroy some variables when
you are done to avoid memory leaks. How does CF handle this?
While I am asking, what about queries? Do hey have to be
destroyed as well? What about queries made with QueryNew?
Thank you for the help.

Control multiple updates and queries within one transaction in JPA

Hi,
I have a question regarding control multiple updates and queries within one transaction. We are using EclipseLink 2.3.1. With below code, will I be able to:
- have all insert, update, select queries committed in one transaction;
- queryGetBalance will return the latest OrgBalance after update;
- if one fails, everything rolls back.
Thanks!
Jeffrey
PS: I realized that I cannot use em.getTransaction().begin() and em.getTransaction().commit(), since I am using JTA.
=============
@PersistenceContext(unitName="Test")
EntityManager em;
em.setFlushMode(FlushModeType.COMMIT);
newTransaction.setAmount(1000);
newTransaction.setType("check");
em.persist(newTransaction);
orgAudit.setUpdateUser("Joe")
orgAudit.setupUpdateTime(time);
em.merge(orgAudit);
Query queryUpdateBalance = em.createQuery("update OrgBalance o set o.balance = o.balance + :amount where orgId = :myOrgId");
queryUpdateBalance.setParameter("amount", 1000);
queryUpdateBalance.setParameter("myOrgId", 1234);
Query queryGetBalance = em.createQuery("select OrgBalance o where o.orgId = :myOrgId");
queryGetBalance.setHint("javax.persistence.cache.storeMode", CacheStoreMode.REFRESH);
queryGetBalance.setHint("javax.persistence.cache.retrieveMode", CacheRetrieveMode.BYPASS);
queryGetBalance.getResultList();
em.flush();

Yes, the operation will be in a single transaction, assuming you are using a JTA managed SessionBean and the code is part of a SessionBean method.

Roles and queries Technical content cube

Dear Experts,
Is anyone aware of any technical content cube that has information about roles and which queries those roles have access to?
ie. I need Roles - Query mapping
I have already looked in to AGR_1251 table but here the direct value is not present. I will have to evaluate the S_RS_COMP and
S_RS_COMp1 authorization objects. Iam looking for another method. So please dont suggest AGR_1251 table.
Thanks,
Kris

Hi Kris,
The way that is there to find out the query - mapping details is already known to you which is the best possible way. But apart from that if you would like to know the roles present in your system then you can simply use the Metadata Repository that is already there and is easily accessible.
1) Just go to the RSA1-> Left hand side bottom -> Metadata Repository -> Click on it or use tcode RSORMDR.
2) You will get list for all the Activated objects in your production system.
3) Locate the Role object from Right hand side.
4) On clicking the Role you will get all the roles that have been created in your system.
If you want the role related to a query then you can simply select the Query object from the metadata repository, you will get list of all queries & further clicking on the query will give you entire details about the query like roles etc.
Also you can use your own method.
You will need to write your own abap to get the details by writing logic which compares the data from both the tables and displays the data accordingly else the best option that is always there is using Metadata Repository.
Thanks

HI Aryan,
No need to create FM on your own. You can copy the FM from Function Group RSAX.
The procedure to create FM extractor is as follows:
1) Create an extract structure.
2) Go to SE80. Select Function Group RSAX , right click and then copy.
3) Give your own name to the function group to copy.
4) Select one appropriate FM from the list of FMs provided. eg FM RSAX_BIW_GET_DATA_SIMPLE.
5)Specify the name of new FM you want to create.
6) Go to SE37 and open the FM you have created by copying from Function Group RSAX.
7) no need to change the import tab.
8) On tables tab, for paramerter name E_T_DATA under asociate name specify the name of extract structure you hav created.
9) Under source code tab make the changes in the source code only to customise it to your requirement. eg: declare the database table you are using, make changes where datasource is in picture, etc.
I have created a generic DataSource with the help of above procedure.. I hope you will find it helpful...

My homepage will load about 30% and then i'm dead in the water. when i close firefox it appears to close but when i try to reopen it tells me that it's already running. started with beta 6 i deleated and loaded ver 5 no change

when i start firefox, everything starts normal then my homepage (igoogle) starts to load, gets to about 30% and stops. from there i can click on links or bookmark and a new tab will open but no page will load. i can't get anywhere. then when i close firefox it appears to close normally but when i try to reopen firefox i get a message that firefox is still running but not responding and the only way to shut it down is to reboot. when it first occured i was running beta 6 (since it became available, i also used beta 4 & beta 5) i then uninstalled beta 6 and downloaded and installed ver 5 same problem. i then did a system restore to a time before the problem.. no luck. i'm not sure what to try next. IE & chrome both work fine

I'm in exactly the same boat - dead at blue screen, only option is to salvage using target mode.
I don't currently have access to another Mac to do target mode. I was planning to buy a new Mac this fall anyway, though. 2 questions in preparation for that purchase:
1) Is there anything I can do before buying a new Mac to make the salvage process more successful? ie, should I spend the time and money going to the genius bar to have them help me get from totally crippled to partially crippled? (As for expertise, I'm a proficient consumer-grade user, but Apple Support walked me through the safe-boot process, etc.)
2) Is Apple going to provide 10.5 once it is released to people who buy a new Mac in these 6 weeks pre-release?
Thanks for your help,
Bailey

Firefox will open 4 or 5 tabs fine, but then will not load any further websites after those first 4 or 5, or allow you to refresh one of those first tabs -- including about:config and the addon page

Firefox 5 worked fine. I installed Firefox 7, and when I ran it, tabs would just say "connecting to..." and hang. Restarting did not help. Websites open fine in IE and Chrome. Disabled all firewalls and antivirus, did not help. Uninstalled and reinstalled Firefox 5, everything worked fine again. This was using Vista 64-bit.
Upgraded to Windows 7, uninstalled Firefox 5, installed Firefox 7, had same problem. Uninstalled Firefox 7 completely (including the profile information, I saved that information in another folder), restarted computer, and installed Firefox 7 using a completely clean profile. Did not install any add-ons, checked to make sure all plug-ins were up-to-date, and updated plugins.
Now when I start Firefox, I can load 3 or 4 or 5 tabs fine -- after those first few tabs are open, I cannot open or refresh any other tabs -- including about:config and the add-on manager -- I have to restart Firefox. The hangup doesn't appear to be related to what websites I am attempting to open, but it looks like the number is the problem. I have run through all of the FAQ procedures, including changing the max number of network connections to 48, and the problem does not seem to go away.
As a side note, I had this same problem when I tried to go from version 5 to version 6 as well. Version 5 is the most recent version that worked on my system.

Can you try Aurora - download it from http://www.mozilla.org/en-US/firefox/channel/
And let us know how it works.

Each time I open my computer, I get a full screen about Firefox and a toolbar that needs a yes or no answer. How do I get rid of this?

I used to be able to press 1 button to get to my Google Home page, but now that I have downloaded the latest version of Mozilla Firefox, the "home page" is now information about Firefox and at the top of my computer, there is a question about security that needs me to say 'no' each time. I do not want to go through these steps every time I start my system.

Best avenue to file complaints about bill and have them resolved

I have been a customer since before 2005 and went with Ntelos in November, I called the night I was at Ntelos to ask Verizon what my contract buy outs were and I was given the prices. The representative tried to offer me whatever promotions she could offer (there wasn't many) and I declined service (there she should have took the initiative to ask about disconnecting). Since my bf opted to keep his number his phone disconnected automatically. I was told my Verizon phone would cycle off within 24 - 48 hours by the Ntelos rep. That was not the case so I called verizon to ensure my phone would disconnect and they told it would at the end of the billing cycle (december 20) which makes sense. I understand I would be responsible for the November - December. Anyways, December 20th rolls around and mind you I've called already to ensure it will take place and it doesn't. I phone in and come to find out the person who took my orders didn't complete the disconnection and now I have to wait until January 20th for it to cycle off and I can finally pay my bill! Well get this in my November - December bill they've charged me $51 for Monthly access (I have a work discount) and $49.99 for insurance and smartphone access for 12/21 - 1/20 and won't refund my $51 as they say that I called out on the phone. I turned the phone on and had voicemails that I think I checked around the time period that they are mentioning (1 day) and that data was used (1 day) I had no outbound calls after December 11th my birthday. Because there are no comments in my account (that I specifically asked them to make) my phone should have been disconnected when I had called in the first of December... really!?! The phone should have been turned off regardless and it was one day out of 30 seriously? I mean the phone has been turned off this whole time and literally only checked to make sure Verizon did their job. I CAN'T HELP IT YOU DON'T KNOW HOW TO DO YOUR JOB, I PUT THE EFFORT IN MULTIPLE TIMES TO LET YOU KNOW MY PHONE NEEDED TO BE DISCONNECTED YOU SHOULD HAVE KEPT RECORD OF IT!!! What really heats me up is that I was told a supervisor would give me a call back after they got out of a meeting and I have not rec'd a call back yet. VERIZON Reps/Supervisors your customers are the reason why you have get a paycheck, I suggest you start treating them a little better. You can't seriously tell me giving me back my $51 for service I DID NOT USE (except according to you for one day you can't even give me details about?) is really going to hurt your pockets. I've been jerked around by your reps for the last 2 months as one told me my contracts were up in January and I shouldn't' be charged for disconnection fees at all, she credited me those termination fees but they later got rejected (after she said her supervisor approved while I was on hold) and NO ONE HAD THE COURTESY TO NOTIFY ME!
I've worked in customer service before and I'll be first to tell you that your reps are not trained very well and you have horrible ethic! You should not charge your customers for an error that was your fault; especially since it was your reps that I asked specifically to note my account and didn't (this isn't my first rodeo with you all, it should be standard procedure to give your reps time to comment before throwing them into another phone call). I'm not doing this for my health here, that $51 could buy diapers and baby food for my daughter and you are crazy if you think I'm going to let it slip through my fingers to line your pockets. I will keep escalating it until you do something about it and I don't care that you already gave me an inconvenience credit I deserve that and my $51 so don't try to justify it that way! This has been way more than an inconvenience, so don't worry I'll inconvenience you as well!

With my new provider I am only using the chat function to settle anything with them so I can save the conversations I've had with them (not that I've had any issues thus far). It should be standard procedure for them to comment your account while they are on the phone with you before hanging up. I should have been annoying and asked them to read back their comments (hindsight ugh!). I'm sorry that you are having to deal with this as well, just know you are not the only one receiving horrible customer service. I'll share with you what I wrote on their Facebook page. They really should take some accountability for their actions and have better follow up on resolving issues (or train their representatives better). I can't stand having to talk to another person time and time again explaining the same thing i just explained to 3 people before them.
Almost immediately, I received some attention after posting this:
Dear Verizon,
I am appalled, especially after reading your credo, that you are refusing to credit back money that is owed to me because your representatives didn't take the necessary time that they should have to comment (after I specifically asked) in my account after I diligently called in multiple times to ensure that my disconnection took place when it was scheduled to and was told that it would (an ongoing issue since the beginning of December). Come to find out that the representatives I spoke with prior to December 20th didn't do their jobs correctly by not entering the disconnection orders in. "Verizon Credo- a set of principles that describes our culture of integrity, respect, performance excellence and accountability. The Credo is a blueprint that directs us to live up to the highest standards possible when serving our customers, shareowners, communities and each other." Let me school you on something here because it appears that you just put that mission statement up on your website 'cause it sounds good, you certainly do not follow through! Accountability: Noun - the quality or state of being accountable; especially an obligation or willingness to accept responsibility or to account for one's actions (i.e. public officials lacking accountability). It doesn't matter that you cannot find any proof in my statements it doesn't change the fact that it happened and I am not a liar. I seriously wouldn't exhaust this must effort had I been lying. I'll take this a step further and reference your statement "we focus outward on the customer, not inward. We make it easy for customers to do business with us, by listening, anticipating and responding to their needs." First of all, when I made my initial call to you all asking what my contract buyout prices were and your rep tried to offer me promotions (or lack there of) to keep me as a customer and I declined she should have "anticipated" my need for disconnection. I shouldn't have had to jump through so many hoops to get my service disconnected from you all and pay my final bill. It's not my fault that your representatives weren't trained well enough to correctly put through disconnection orders. Based on my interactions with your customer service I could see where people would disconnect their services regularly!!!!! You are not making it easy for me to severe ties with you and conduct BUSINESS and you are not responding to my NEEDS. I think you forget that I could be a potential customer in the future. If it's one thing I learned from my Communications Degree is that negative feedback will reach more consumers vs. positive feedback of a company and how they handle their business. I have 1,000 plus facebook friends and twitter followers so I'm pretty sure my negative experience could reach quite a few people! You say you have integrity? How is it moral uprightness to charge me for a whole month of service (regardless if the phone was turned on once) for a billing period that shouldn't have existed if your customer service reps did their job correctly? I suggest that you all take a good look at the way you are treating your current customers because we are the reason you get a paycheck! You should make your customers a priority especially if they've been with you for 10 + years regardless if they are disconnecting service or not! How about following through, taking ACCOUNTABILITY and having that supervisor representative call me back from my phone conversation last night like I am a priority (how every customer should be treated) and helping me get the money that I am owed, regardless if the phone had been turned on for a short period (your rep couldn't even tell me what numbers I supposedly called - exactly the phone has been off since December 20th if not before unless turned on to confirm disconnection)! Oh but let me guess did you all forget to put that in my account comments as well? Probably like there is no mention of the formal complaint I filed against some of your representatives that there was supposedly no ticket number for. I thought I was going to regret leaving Verizon for another provider but it turns out that I only wish I would have left sooner and actually gone to a authorized dealer/ Verizon Store to process my disconnection because your customer service line is a joke!

We have always used one iTunes account and I want to crate a new account for my daughter. What is the best way to go about this and will she need to download free apps again?

Not going to happen the way you want it to.
When you add a gift card balance to the Apple ID, it's available for the Apple ID.
Probably best to create unique Apple ID's for each... this will also make things easier in the future as purchases are eternally tied to the Apple ID they were purchased with.

Hi, I've just purchased and installed an upgrade from Lightroom 4 to 5. It doesn't seem to handle raw files authored with a new Nikon D750 camera. I spoke to the sales rep about this and he gave me a link to the 8.6 DNG converter page with instructions to download. 8.6 only works with Mac OS 10.7-10.9, according to the page. I'm running Yosemite, Mac 10.10. Please can you tell me my options? Lightroom 4 worked beautifully with my older cameras' raw files so I would like to continue using the application. What should I do? How soon will Lightroom 5 be able to deal with raw files from a D750. Many thanks, Adam.

Until the next version of Lightroom is released, you need to use the DNG Converter version 8.7RC to convert your RAW photos to DNG and then import the DNGs into Lightroom.
