All confused about versions!!

Hello,
I'm sorry if this has already been explained in parts else where, but I need a totally fresh clear picture of what is going on. This is my problem, although I would say I am fairly comfortable with Java programming; and I go enjoy it alot, I am only just about comming to grips with all the different versions and the ways in which it is organised. This is where my problem lays.
I am using jdk1.3.1, and Forte version 2. I take it this is J2SE. Now I want to start programming Secure Sockets (am working on client server architecture), however from searching through the different classes available I found that I don't have javax.net.ssl. So I think.. lets just download J2EE. But from the looks of it all the specifications required do not list Windows 98 which is what I am (still?!) using. I am stuck... can I just download classes?! I don't know what to do.
Somebody please help a confussed DOS C/C++ programmer :-)
-thanks

javax.net.ssl is a standard part of the 1.4 API, the easiest way of using it could be upgrading to 1.4.1 or 1.4.2 Beta.
But maybe you can still download it from http://java.sun.com/products/jsse/ ...
Forget about the EE stuff, it's not what you need :)

Live Update confused about versions installed?

I have a MSI Neo4 Platinum and first I installed the Marvell LAN Drivers via Live Update (Version 7.14.1.3). This driver did however seem to be very unstable (the network connection dropped after a few minutes of use), so I went to Windows Update and picked the Marvell Driver there. It shows up under the Driver Tab as version 7.29.4.3". This driver seems very stable and my dropped connection problem is gone. I had this problem on two different installations of this board.
When I now run Live Driver, it incorrectly reports that my current version is 7.14.1.3 (not 7.29.4.3). It is obviously confused about shich version I'm running.
Anyone else seen this problem?

olavt,
Do not bother with Live Update. If you want to update anything, do it manually. Also for Mobo Drivers, usenVidia nForce Drivers
Take Care,

I am confused about Icloud. I have a 5 year old Macbook, a 2 year old macbook and a 5 year old mac mini. What exactly do I need to do to get all this connected via Icloud. I also have an Iphone 3G. Help please!

I am confused about Icloud. I have a 5 year old Macbook, a 2 year old macbook and a 5 year old mac mini. What exactly do I need to do to get all this connected via Icloud. I also have an Iphone 3G. Help please! Also, I still don't understand exactly what the benefits are. At the moment it seems a lot of hassle to change a system that's been working perfectly well and that I'm very happy with. I'm not at all sure whether the mac mini (1.66 GHz INtel Core Duo) can be brought up to the relevant spec to run ICloud. Any thoughts?

There are two aspects to iCloud. One is simply getting an account, or migrating a mobileme account to iCloud. The second part is using the various features of iCloud to sync contacts, calendars, use music match or photo sharing, and store iWorks documents.
First to get an iCloud account:
If you have a mobileme account, you can migrate by simply logging onto www.icloud.com (ignore any references to Lion and just click through to complete the migration). If you have OS X Lion or an iOS 5 mobile device, you can create an iCloud account on that device using any valid AppleID.
Once you have an account, you can use JUST the mail account if you wishi - it is a standard IMAP account so you would set it up like any other IMAP email account you have, in whatever client program you use to read email.
To use the OTHER feautes of iCloud, your computers will have to be running OS X Lion (10.7). Your iPhone 3G will never be able to use iCloud as it cannot run iOS 5 (you need a min. of an iPhone 3GS to run iOS 5).
The requirements for OS X Lion are here - http://www.apple.com/macosx/specs.html You need a min. of a Core 2 duo processor so you mini is not capable of running Lion.
So, in your case, the single reasons for iCloud would be if you have a mobileme account, then use the online www.icloud.com to migrate your account so you do not lose your @me.com email address. You can use iCloud email (without using any other iCloud features) by setting it up as IMAP mail with these settings - http://support.apple.com/kb/HT4864
If you want an iCloud account and do NOT already have a mobileme account, you will need to upgrade one machine at least to Lion in order to be able to create an iCloud account.

I am so confused about iCloud. My husband says he never set it up but all is information is on both his iPad and iPhone. How can that be and do I have to have iTunes Match?

I am so confused about iCloud. My husband says he never set it up but all is information is on both his iPad and iPhone. How can that be and do I have to have iTunes Match?

"All his information" may or may not include things customarily stored in iCloud. Perhaps all the information is on both devices because they were both recently synced using the same iTunes sync.
Do you have to have iTunes Match? No. Many folks do not have iTunes Match. The music purchased from iTunes is always available to the purchaser. Other music is stored in iTunes on the person's computer.

Confused about DATA CLIENT version

Dear Concern,
We have data services Version 12.2.0.0 and SAP BO Enterprise
X1 Version Product: 12.1.0. We have tried to work with the
data client 3.1 as well as 3.2 which you have provided during
the installation process. When we are
trying to create Repository with data client version 3.1 we
are getting the message like ''Data Services Repository
'REPO' version-12.1 is incompatible with the version-12.2.
(BODI-3015002)".
with data client 3.2 we also get the error message like" PM
Cannot run version <12.2.0.0> of the product against the
newer version 12.2.2.0000> of the repository. Please upgrade
the 6802 2101081632 REP-100105 1/30/2012
12:36:36 PM product to version <V12.2.0.0000> or later.
I am confused which version of client is actually perfect my
environment. Would you please suggest us?
Thanking you,
Shawkat

What i understand from your message is that you have a version conflict with the client and repository. As far as i know, you need to have both with same versions to avoid this.
If you have a SAP id, you can get both with same versions.

PSE 7 confusion about folder location, help needed

Here's some background: I'm using PhotoShop Elements 7 on Win XP. I have an external firewire hard drive I use for overflow/backups. Originally, this showed up as a K: drive on my system.
I added a RAID controller and two more drives to stripe as a single drive for temp space rendering movies. This ended up as a K: drive and the external moved to L: However, when I did this there were some pictures from my catalog that I had on the external drive. I have used File > reconnect missing files to handle the moves, but PSE is still confused (very).
PSE has started to mix up the RAID (K:) and external (L:) content. If I move a set of pictures (e.g. a folder of them) onto the external drive (L:) via drag and drop in the folder location view, the folder will show up empty on the L: heirarchy, but will show up as a gray folder icon in the K: RAID drive hierarchy. If I open up windows explorer, the RAID drive will appear empty. In other cases (I'm not sure when/how yet), pictures physically end up on the RAID drive itself instead of the external. I have uninstalled both the external drive and the RAID drive and reinstalled them both, but they are still getting confused in the folder view by PSE. I've also tried moving content outside of PSE and just reconnecting missing files, but it still wants to put things under the K: RAID drive instead of the external L:.
I've searched everywhere I can think of for a description of what gray folder icons in the folder location view means and can find none. I'm not sure how to convince PSE that there's nothing on the RAID K: drive and it shouldn't try to connect the two. Any suggestions?
Thanks,
Jim

Thank you! I ran psedbtool and the output shows the catalog has the wrong drive letter for the L: drive.
Is there a way to make PSE forget about the K: and L: drives that it is so confused about so that it can relearn of their existence? If I use the drive letter reassignment to fix PSE, it will break other apps that are now dependent on the current drive letter assignments. I've tried removing all files from the L: drive, but it's still remembered as part of the catalog.
Thanks,
Jim

Confused about conversation grouping Lion vs. Snow Leopard

Hello All,
I just upgraded. Literally just finished. I was checking out mail, and I am confused about how Mail 5 groups messages for conversations. In SL I had Mail group related messages as well, and it's a feature I really enjoy. Conversations just makes it that much better. But, I notice that Lion groups message differently than both SL and iOS. Now, it is no longer grouping emails that are all from various people but are part of the same thread. It is grouping multiple messages from the same sender, even if they have nothing to do with each other, or are only loosely connected.
It used to be (and still is on my iPhone) for example, that all the emails eminating from a single thread topic on one of my class forums would all group together. They have the same subject line and formatting. It was heaven. Will there be no way of doing this?
Also, now all the emails from the teacher of that class, regardless of the relevancy or subject line, group together in one conversation. It's annoying in a way, but I think I can get used to that. Does anyone know if these will be able to be changed in the future?
Thanks

As a Mac power user - LION IS A DISAPPOINTMENT
Apple needs to seriously consider briniging back
• SPACES: the capability to move up as well as down to access applications
     AND have applications stay in a desgnated space makes it much easier
     to run multiple applicatioins - especially in a multi-monitor environment
• SAVE AS: Saving various versions of a file is difficult with Lion.
    If I want a 3 versions of a document - with different pictures, it takes too many "clicks" to accomplish
     this task. LET ME CHOOSE HOW I STORE FILES
• COPY COMMAND: Snow Leaopard allowed me to copy files to a storage device AND if the file
     was already written to the device - the option to NOT REPLACE the file existed. This made it
     easy to backup work on a portable drive.
     LION ONLY has two options - copy all or make an addition copy of the file, causing storage bloat
APPLE NEEDS TO SERIOUSLY CONSIDER PUTTING THESE FEATURES BACK INTO THEIR OS FOR THE BUSINESS AND POWER USER

Confused about usage of usage types (NW2004s vs. NW 7.1 vs. NW mobile 7.1)

Hello all
I'm confused about the different combination possibilities / restrictions when it comes to compare NW2004s, NW PI 7.1 PI and NW Mobile 7.1. I already consulted the Master Guides and technical installation guides but am still confused. So if someone could shed some more light on it it would be great!
We plan to implement our interfaces, whether internal (system to system) or external (customers, suppliers) using XI (now called PI, right?). But we also intend to develop and run mobile apps (occasionally conected ones). So my questions around it are:
1) Do we need to install at least two separate servers for this? I mean:
- 1 server for SAP Netweaver PI 7.1
- 1 server for SAP Netweaver Mobile 7.1
2) Or is possible to have all this on one single server using SAP Netweaver 2004s with usage types AS ABAP, PI and Mobile.
3) Is usage type AS JAVA required when choosing usage type Mobile?
4) What would you recommend for production environments (note: I'm aware of the sizing / scaling question but I'm only interested in some kind of best practices advices in terms of maintenance, patching, etc.).
Thanks anyone for some input on it
BR
Renaud

Thanks Russell and Larissa for your clarifications.
Re-checked the master guide for NW 2004s (7.0) and now found the relevant text in chapter 3.3.1 on pages 30 + 31. Must have overlooked it the 1st time.
Other questions:
a) What is the difference between a installation of NW 7.0 with usage type AS ABAP and PI compared to NW PI 7.1 ?!?
b) What is the difference between an installation of NW 7.0 with usage type AS ABAP and Mobile compared to NW Mobile 7.1 ?!?
Do the 7.1 versions contain real newer releases or is it just another packaging of same components? What are the advanteges of the 7.1 versions?
Thanks again in advance for some more clarification!

Udev: confusion about identifier ATTRS{idProduct}

Hi,
i'm confused about how exactly udev identifies a device, imho the idProduct identifier is (in this specific case) inconsistent.
Short story:
'lsusb' and 'udeadm info' indentify the devices idProduct as "1002", but to get udev rules working i have to use ATTRS{idProduct}=="1001" though.
Long story:
I have this usb-to-midi device (midisport 2x2), which needs to load firmware to work (midisport-firmware). This is the udev rule to load the firmware:
#/etc/udev/rules.d/42-midisport-firmware.rules
# MidiSport 2x2
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="0763", ATTRS{idProduct}=="1001", RUN+="/sbin/fxload -s /usr/share/usb/maudio/MidiSportLoader.ihx -I /usr/share/usb/maudio/MidiSport2x2.ihx -D %N"
This rule ("idProduct=1001") works!
Changing "idProduct" to "1002" does not work.
However, here's the output of
~# lsusb
Bus 003 Device 007: ID 0763:1002 Midiman MidiSport 2x2
and

which both indicate, the correct idProduct would be "1002"!?
The midisport box is the only device where this inconsistence appears, all other usb-devices (hdds, sticks, sound card, dvb-t stick, mp3 player) get identified as expected.
I want to know, if anybody can explain this/ if anybody has had similar experiences!

Looking at the udevadm info output, it shows ATTR{idproduct}=="1002" and ATTRS{idproduct}=="0001" and your rule uses ATTRS{idproduct}=="1001".
Have you tried with just ATTR{idproduct}=="1002" (note no S)? Looking at the output of info, I would still not expect ATTRS{idproduct}=="1001" to work, but udev's changed a fair bit in the last few years and the old bible for rules is way out of date.

Confused about the new Creative Cloud

Dear all,
Since I read adout the new Creative Cloud I am confused about what is going to happen to my license for Adobe Lightroom. Are they going to still maintain the desktop applications as well or will I have to pay for a yearly license if I want to use the new versions of Lightroom?
I am a casual photographer and I love using Lighroom for my pictures but I don't think that paying for a yearly license because I am not spending a lot of time editing pictures.
Can someone clarify this for me?
Many thanks,
Lucian

The CC is geared towards Pro users, schools etc. LR spans both Pro and casual users. So from what I can garner Lightroom will stay as it is for the next iteration at least. I quoted that bit as my opinion is that that is the very reason why Lightroom will be available outside the cloud with a cloud version available with intergration features with the rest of the CC suite.

Confused about the default schema

Hi,
I am a little bit confused about the schema concept.
I want to create a new schema called APP and then create several users and roles based on the schema APP. The default schema for the users should be APP achema.
How can I make the schema APP the default schema for the new users that I am creating?
I feel that there are some schema design concepts that I have to learn. Is there any resource on the internet that I can read and learn more about oracle schema design best practices?
Any help would be appreciated,
Ali

A schema holds object definitions, and in the case of table & index objects the schema also holds the data.
A user owns the schema.
Therefore the user 'owns the definitions (including any functions, procedures, sequences, tabels, etc.)
Other users may be granted access to some, or all, of the objects in a schema. This is done through the 'GRANT ...' command. For example, consider the following steps:
1) create user app_owner
2) create table object test owned by the app_owwner
3) create user app_user
4) grant select, update, insert and delete on app_owner's test table to app_user
5) add synonyms to avoid needing to qualify the table's schema name.
done as follows:

Confused about word processing on macs - do i need to buy extra software?

Hi, am about to buy a new macbook (first mac- am switching over) but am very confused about the word processing facilities which come with. do i need to buy microsoft office for mac to use word etc or can i use something similar which comes with OS X (is it text edit?)? is this compatible with a word environment at work? thanks!
macbook Mac OS X (10.4.7)

I've personally always hated Microsoft Word, but have it because that's the "standard," and at the time I bought my MacBook, the Intel Mac version of NeoOffice (which is free) wasn't out yet. NeoOffice is now out for Intel-based Macs, and it seems to be every bit as powerful as Microsoft Office (and quite compatible).
However, for most things I do, I've found I actually like Pages the best. It's very easy to use, though if you do any special things in word processing it might not meet all your needs. It will open Word documents, and if you have to send something as a Word document, you can export it in Word format.
I would recommend that you try out the Pages trial that came with your Mac, and download NeoOffice for free. Try them both - go with what you like and what works best for you. I use Pages the most, NeoOffice for things Pages won't do, and Word if I'm forced to. (And I always have my old WordPerfect that I've used for years that I can run in Windows.)

Confuse about the injecting entity in EJB 3.0?

Hi all,
I have an customersBean which is inherit from customersRemote and my problem is i' am little confuse about injecting the entity(customer).
Where can you apply the EntityManagerFactory is it outside on EJB or Inside the EJB? means outside EJB is use the web application or java application. i have and example.
this is inside on EJB...............
public class CustomersBean implements com.savingsaccount.session.CustomersRemote {
@PersistenceContext(unitName="SavingAccounts")
EntityManagerFactory emf;
EntityManager em;
/** Creates a new instance of CustomersBean */
public CustomersBean() {
public void create(int id, String name, String address, String telno, String mobileno)
try{
//This is the entity.
Customer _customer = new Customer();
_customer.setId(id);
_customer.setName(name.toString());
_customer.setAddress(address.toString());
_customer.setTelno(telno.toString());
_customer.setMobileno(mobileno.toString());
em = emf.createEntityManager();
em.persist(_customer);
emf.close();
}catch(Exception ex){
throw new EJBException(ex.toString());
in web application, i'm using the @EJB in customer servlets.
public class CustomerProcessServlet extends HttpServlet {
@EJB
private CustomersRemote customerBean;
blah blah inject directly coming request field from jsp.
}

Confused about transaction, checkpoint, normal recovery.

After reading the documentation pdf, I start getting confused about it's description.
Rephrased from the paragraph on the transaction pdf:
"When database records are created, modified, or deleted, the modifications are represented in the BTree's leaf nodes. Beyond leaf node changes, database record modifications can also cause changes to other BTree nodes and structures"
"if your writes are transaction-protected, then every time a transaction is committed the leaf nodes(and only leaf nodes) modified by that transaction are written to JE logfiles on disk."
"Normal recovery, then is the process of recreating the entire BTree from the information available in the leaf nodes."
According to the above description, I have following concerns:
1. if I open a new environment and db, insert/modify/delete several million records, and without reopen the environment, then normal recovery is not run. That means, so far, the BTree is not complete? Will that affact the query efficiency? Or even worse, will that output incorrect results?
2. if my above thinking is correct, then every time I finish commiting transactions, I need to let the checkpoint to run in order to recreate the whole BTree. If my above thinking is not correct, then, that means that, I don't need to care about anything, just call transaction.commit(), or db.sync(), and let je to care about all the details.(I hope this is true :>)

http://www.oracle.com/technology/documentation/berkeley-db/je/TransactionGettingStarted/chkpoint.html
Checkpoints are normally performed by the checkpointer background thread, which is always running. Like all background threads, it is managed using the je.properties file. Currently, the only checkpointer property that you may want to manage is je.checkpointer.bytesInterval. This property identifies how much JE's log files can grow before a checkpoint is run. Its value is specified in bytes. Decreasing this value causes the checkpointer thread to run checkpoints more frequently. This will improve the time that it takes to run recovery, but it also increases the system resources (notably, I/O) required by JE.
