Confusion about stream API

I am just starting doing client-server programming, and I/O streams and such, but I was following a tutorial that used a DataOutputStream and a DataInputStream. The client server in that case was just passing text back and forth. But the API says that this stream class was for java primitive types. First off I didn't know String was a java primitive type (char yes, but not char). Second it seems like this would be a bad choice to use - perhaps InputStreamReader would be better.
This may just be an esoteric question, but I just want to understand streams more...and some of the API documentation I don't know if I'm really understanding correctly.

I am following the minimal client/server code from this site:
http://www.cs.unc.edu/Courses/jbs/lessons/java/java_client_server1/
as a primer to learning about it. I guess I'm just questioning the input and output stream they are using because I really dont' know that much about streams in general and why I would use one over the other in what cirumstance. After reading more about streams, it seems like a inputStreamReader and inputStreamWriter woudl be more appropriate but I don't know if I am just misunderstanding the API.

Confused about SOAP

Hi all,
As far as I know, SOAP is initially designed to be an XML based
RPC protocol.
But Java API for XML Messaging (JAXM), which is actually a
messaging API (and not RPC), is also based on SOAP.
How do they fit to each other?
In a few words, what does actually SOAP define?
I am confused about that, can you help me?
Any idea will be appreciated.
Thank you

In a few words -- no. Try here:

[SOLVED] Confused about Mobility Radeon HD 3200

I've always found hard to find good information about this card - some sources, even, contradict themselves. All what I know is that it is an integrated graphics card and that it features the RS780M chipset. These are some tips I've got from the system logs:

I also found good (?) information, or at least a clearly-explained article, here. After reading it, UVD appears as the AMD's counterpart of NVIDIA's VDPAU for video acceleration.
What I'm not sure about, is:
- Does it support video acceleration? I'd like to offload video processing to the GPU, but am not sure if my card and the open-source drivers support it or not. Wikipedia's article about VDPAU states it comes from NVIDIA, but then it says it has an open-source implementation.
- What has gallium to do with it? What gallium drivers should I enable in mesa? And what about DRI drivers?
I configured mesa as follows:
./configure --prefix=/usr \
--sysconfdir=/etc \
--with-dri-driverdir=/usr/lib/xorg/modules/dri \
--with-gallium-drivers=r600 \
--with-dri-drivers=radeon \
--with-llvm-shared-libs \
--enable-gallium-llvm \
--enable-egl \
--enable-gallium-egl \
--with-egl-platforms=x11,drm \
--enable-shared-glapi \
--enable-gbm \
--enable-glx-tls \
--enable-dri \
--enable-glx \
--enable-osmesa \
--enable-texture-float \
--enable-xa \
--enable-vdpau
Not sure if I missed something, though.
I am very confused about how Linux manages graphics, and what all those layers are for. DRM, DRI, VDPAU, VA-API, gl, gl3, xv, xvmc... it's a mess!
Thanks in advance.

The feature matrix might help. The easy part to answer is that the 3D driver is split into two parts: DRM which is part of the kernel and DRI which is in userspace and comes from the mesa package.
Xv is an Xserver extension supported by pretty much all drivers. Found in the DDX (xf86-video-*), it uses features of the card to speed up the display of video (but not decoding). It can either do this by using the "video overlay" or creating a shader.
Now if you want to use Xv but also offload decoding to the card, you need a video acceleration API. The ones to choose from are XvMC, VA-API, VDAPU in increasing order of feature support. They were developed by Xorg, Intel, Nvidia respectively but anyone is free to implement them. I don't think it's correct to call UVD a counterpart of VDPAU. UVD is a bunch of registers on newer AMD cards. And if you sent bits to those registers in the right way, you can implement VDPAU.
The other way to implement VDPAU (say if the documentation for UVD registers was not released) is to use gallium. There is a gallium state tracker which can still do it at the expense of being slower. It is a hack whereby you convert video frames to polygon textures and make the OpenGL part of the card think that it's calculating part of a 3D scene when really it's decoding video.

Confusion about TreeMap

Hi,
I'm currently studying for SCJP exam and am confused about the following code.
     public static void main(String[] args) {
     TreeMap myMap = new TreeMap();
     myMap.put("ab", 10);
     myMap.put("cd", 5);
     myMap.put("ca", 30);
     myMap.put("az",20);
     NavigableMap myMap2 = myMap.headMap("cd", true);
     myMap.put("bl",100);
     myMap.put("hi",100);
     myMap2.put("bi", 100);
     System.out.println(myMap.size() + " " + myMap2.size());
     }When I run it, it outputs 7 6.
What I'm confused about is how when after the line NavigableMap myMap2 = myMap.headMap("cd", true);and values are being entered into the myMap object, that it is still possible for them to be entered in the NavigableMap object? Are the 2 entities not seen seperately? Is it to do with the "inclusive" field of the headMap method.
The solution states that the myMap contains the objects "ab","cd","ca","az","b1","h1","bi"
and myMap2 "ab","cd","ca","az","b1","bi".
But how when adding key-value pairs do both objects (myMap,myMap2) get considered for putting into?
Thanks.

From the API:
headMap
public NavigableMap<K,V> headMap(K toKey,
boolean inclusive)
Description copied from interface: NavigableMap
Returns a view of the portion of this map whose keys are less than (or equal to, if inclusive is true) toKey. The returned map is backed by this map, so changes in the returned map are reflected in this map, and vice-versa. The returned map >supports all optional map operations that this map supports. So myMap2 contains all the elements from myMap that are <= "cd" (which are all except "hi"), and changes in either map are reflected on both, as stated.

Confused about capability of extensions

Hi,
I'm a bit confused about what extensions are used for. I've
never used any, and can't seem to figure out what they're for
besides copy-paste.
I looked at dreamweavers help file about creating extensions,
but all it does is allow you to make a code block that can be
inserted at a click of a button.
Is there a way that you can make extensions that actually ADD
options to dreamweaver menus? Like when a user right clicks
somewhere, or something like that? Like if the user clicks anywhere
a link to go to google.com is on the menu or something, thats
simple.
What I want is to build a window that is an extension. You
can find what I am attempting to accomplish at:
Here
What can you do with extensions? Can you actually add onto
dreamweavers product?

Dreamweaver creates a local copy of menus.xml that overrides

Confused about deleting pics on iphone

I know this probably has been answered in a previous thread and have saw some thing that help, but I am still a bit confused about photo stream and photos.
What is the difference from how photos get saved (on an iphone) in photo stream vs. just being stored as memory?
Do they, photos, get stored in the cloud or physically on my phone?
How come when I go to delete photos on my iphone I get a message that warns it will delete on all my devises to include my mac?
When I deleted a few pics from my iphone they got deleted from my mac. In a nutshell how can I ensure that my mac will permantly store all of my pics regardless if I delete them from my iphone?
Thanks very much

ok ill try to help
photostream stores the pics you take for 30 days. if you delete them from here removes from all devices.
camera roll is the pics you take. can be deleted from device and only device. to save these import to your computer see.
http://support.apple.com/kb/HT4083
your photo library is imported from computer to phone. you can delete these from device they have to be synced off

I am confused about something. How do I read a book on my MacBook Pro? I can't find the iBook app anywhere, which is what I use on my iPad. The book I want to read is in my iTunes but I can't click on it. My iBook library does not show up in iTunes.

I am confused about something. How do I read a book on my MacBook Pro? I can't find the iBook app anywhere, which is what I use on my iPad. The book I want to read is in my iTunes but I can't click on it. Some of my iBooks show up in my iTunes but they are "grayed" out. The only books that respond in iTunes are audiobooks and that's not what I'm looking for. Is this a stupid question?

Nevermind - I answered my own question, which is I CAN"T READ ANY BOOKS I purchased in iBooks on my MacBook Pro. If I want to read on my mac I have to use Kindle or Nook. Which means any book I've already purchased through iBooks has to be read on my iPad. Kind of a drag because there are times when it's more convenient for me to read while I'm sitting with my Mac.

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)

Confused about logical table source

Hi,
I'm confused about logical table source(LTS), there are 'General', 'Column Mapping', 'Content' tabs in
LTS, in General tab ,there are some information,like 'Map to there tables' and 'joins',
just here, we have created relationships in physical layer and BMM layer, so I would like to ask what's the use of the 'joins' here?

Hi Alpha,
Valid query, when you establish a complex join it is always between a logical fact and dimension table.Consider a scenario,
Example:w_person_dx is an extension table not directly joined to a fact but joins to a dimension w_person_d.
When you model the person_d tables in BMM, you ll have a single logical table with w_person_d as source.If you have to pull columns from both w_person_d and w_person_dx tables in a report, you add dx table as inner join to persond table in the general tab.Now when you check your physical query, you can see the inner join fired between the two dimensions.

Java Mapping with Stream API

Hi,
Can you please let me know when java mapping with STAX will be supported in Netweaver XI?
Regards
Sudhir

Hi Sudhir,
STAX is Stream API for XML. It works similar to SAX but is a pull based model. It can also work with multiple XSD's...
XI support of STAX will moslty be supported when XI supports Java EE 5. We can say that this will be supported very soon...
http://www.xml.com/pub/a/2003/09/17/stax.html presents the overview of STAX.
Hope this helps

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 :>)
michael.

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.

Confused about extending the Sprite class

Howdy --
I'm learning object oriented programming with ActionScript and am confused about the Sprite class and OO in general.
My understanding is that the Sprite class allows you to group a set of objects together so that you can manipulate all of the objects simultaneously.
I've been exploring the Open Flash Chart code and notice that the main class extends the Sprite class:
public class Base extends Sprite {
What does this enable you to do?
Also, on a related note, how do I draw, say, a line once I've extended it?
Without extending Sprite I could write:
var graphContainer:Sprite = new Sprite();
var newLine:Graphics = graphContainer.graphics;
And it would work fine. Once I extend the Sprite class, I'm lost. How do I modify that code so that it still draws a line? I tried:
var newLine:Graphics = this.graphics;
My understanding is that since I'm extending the Sprite class, I should still be able to call its graphics method (or property? I have no idea). But, it yells at me, saying "1046: Type was not found or was not a compile-time constant: Graphics.

Thanks -- that helped get rid of the error, I really appreciate it.
Alas, I am still confused about the extended Sprite class.
Here's my code so far. I want to draw an x-axis:
package charts {
    import flash.display.Sprite;
    import flash.display.Graphics;
    public class Chart extends Sprite {
        // Attributes
        public var chartName:String;
        // Constructor
        public function Chart(width:Number, height:Number) {
            this.width = width;
            this.height = height;
        // Methods
        public function render() {
            drawAxis();
        public function drawAxis() {
            var newLine:Graphics = this.graphics;
            newLine.lineStyle(1, 0x000000);
            newLine.moveTo(0, 100);
            newLine.lineTo(100, 100);
I instantiate Chart by saying var myChart:Chart = new Chart(); then I say myChart.render(); hoping that it will draw the axis, but nothing happens.
I know I need the addChild method somewhere in here but I can't figure out where or what the parameter is, which goes back to my confusion regarding the extended Sprite class.
I'll get this eventually =)

Confused about standby redo log groups

hi masters,
i am little bit confuse about creating redo log group for standby database,as per document number of standby redo group depends on following equation.
(maximum number of logfiles for each thread + 1) * maximum number of threads
but i dont know where to fing threads? actually i would like to know about thread in deep.
how to find current thread?
thanks and regards
VD

is it really possible that we can install standby and primary on same host??
yes its possible and i have done it many times within the same machine.
For yours confusion about spfile ,i agree document recommend you to use spfile which is for DG broker handling if you go with DG borker in future only.
There is no concern spfile using is an integral step for primary and standby database implementation you can go with pfile but good is use spfile.Anyhow you always keep pfile on that basis you created spfile,i said you make an entry within pfile then mount yours standby database with this pfile or you can create spfile from this pfile after adding these parameter within pfile,i said cause you might be adding this parmeter from SQL prompt.
1. logs are not getting transfered(even i configure listener using net manager)
2.logs are not getting archived at standby diectory.
3.'ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION' NEVER COMPLETE ITS RECOVERY
4. when tried to open database it always note it 'always' said system datafile is not from sufficiently old backup.
5.i tried 'alter database recover managed standby database camncel' also.Read yours alert log file and paste the latest log here..

Confused about passing by reference and passing by valule

Hi,
I am confuse about passing by reference and passing by value. I though objects are always passed by reference. But I find out that its true for java.sql.PreparedStatement but not for java.lang.String. How come when both are objects?
Thanks

Hi,
I am confuse about passing by reference and passing
by value. I though objects are always passed by
reference. But I find out that its true for
java.sql.PreparedStatement but not for
java.lang.String. How come when both are objects?
ThanksPass by value implies that the actual parameter is copied and that copy is used as the formal parameter (that is, the method is operating on a copy of what was passed in)
Pass by reference means that the actual parameter is the formal parameter (that is, the method is operating on the thing which is passed in).
In Java, you never, ever deal with objects - only references to objects. And Java always, always makes a copy of the actual parameter and uses that as the formal parameter, so Java is always, always pass by value using the standard definition of the term. However, since manipulating an object's state via any reference that refers to that object produces the same effect, changes to the object's state via the copied reference are visible to the calling code, which is what leads some folk to think of java as passing objects by reference, even though a) java doesn't pass objects at all and b) java doesn't do pass by reference. It passes object references by value.
I've no idea what you're talking about wrt PreparedStatement, but String is immutable, so you can't change its state at all, so maybe that's what's tripping you up?
Good Luck

PS: I will venture a guess that this is the 3rd reply. Let's see...
Ok, second. Close enough.
Yeah, good on yer mlk, At least I beat Jos.

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
