How to work with the remote file system

Hi all,
I want to know how we can work with the remote file sytem.
Code should be some thing like
File f = new File("//10.22.33.122/images")
images is share name..
i want the file names of all the images in that shared folder...
Thanks in advance,
Srinivas N

try this one:
File f = new File("//10.22.33.122/images")
File[] files = f.listFiles(new FilenameFilter() {
public boolean accept(File dir, String name)
// Specify the extentions of files to be included.
return name.endsWith(".bmp") || name.endsWith(".gif");
// get names of the files
String[] fileNamesArray = null;
for (int indx = 0; indx < files.length(); indx++)
fileNamesArray[indx] = files[indx].getName();
return fileNamesArray;

How to work with folios from external systems?

I need to group a content into a hierarchical structure using folios. I need to add document to the particular slot in the folio. Documents are generated by the external application and checking-in thru the SOAP interface. There is no services regarding folios for SOAP in UCM. Is there any solution to resolve this problem? It is possible to use workflow processes to route documents to particular slots during the SOAP check in action?

The services exist to do what you want, but they are not documented. I suggest logging a service request with support in order to request an Enhancement Request to prompt the documentation to be created. the more requests that come in the more priority can be given as far as I understand it.
If you know how to customize the CS pretty well you can go look at the Folios component in the CS custom directory (remember not to directly modify it however) and look at the service definitions and that may give you some ideas. If you do not know how to read the service definitions ( and some are not clear since they call Java sub methods that are not exposed clearly) you can look at the Customizing guides in the documentation.

How i can start working with Java?

Right now i am having only 8 months of exp in ABAP. can any one help me out to start working with Java specially for Netweaver Purpose

It is great if you can get yourself familiar with java syntax, as is the case with any new langauage. However, the worst thing you can do is just code java in a top down approach. If you are not familiarizing yourself with OO concepts and best practices, then you are going to miss two important benefits that you will get from using OO programming - Reusability and flexibility in the frameworks that you develop (leveraging design patterns).
These benefits will also be directly obtainable when you use ABAP objects.
I am working in the opposite direction at the moment. I have some java experience, and I am starting to learn ABAP. I have used ABAP objects in my first project, and it was actually much better than I thought it would to be.
Java and OO programming will be an ongoing learning experience. You will not be an expert for quite some time. I do not consider myself to be an expert by any means, and I've be studying OO and java for a few years.
There is a fantastic book that explains OO concepts clearly, in much easier terms than the Gof "Design Patterns" book:
Java Design: Objects, UML, and Process by Kirk Knoernschild
You can read a few chapters at www.kirkk.com. (Use the JOUP link).
Hope this helps you.

How to work with EEWB tool in CRM and how to assign it to PCUI

Hi Friends,
Can any body will suggest me how to work with EEWB tool in CRM to add new fields ,i need to attach the fields to a GUI screen and same to PCUI also,
And how to attach a search help for those fields,is the tool will automatically will create the search helps or it is similar as we do in abap,
So can any body suggest me to get a material on this ,
Thaking you
Regards

Following are the steps involved in general :
1. Select the filter Worklist and enter your name in the input field of the object list selection. Press the enter key. Your object list is displayed.
2. Place your cursor on the highest node(PROJECT BY XXXXXX). Select Create project from the context menu by right-clicking on it. You see the dialog box Create project.
3. Enter a project name, description, packages, and namespaces for each system used. Leave the dialog box by pressing the enter key.
Specify transport requests. The Project is created and appears in the object list.
4. Place your cursor on the new project in the object list and select Create extension in the context menu. You see the dialog box Create extension.
5. Enter a name and description. Define a Business Object and extension type. Press the enter key.The extension is created and appears in the object list below the project.
6. Place your cursor on the new extension in the object list and select Call wizard in the context menu. The wizard for the extension action starts automatically.
7. Fill in the input fields following the notes on screen and end the wizard by clicking on Complete.The extension tasks have been created and appear in the object list.
Project and extension are created !
Also take care that you have the Transport Requests and Save the Project and Extensions against a Development Class !
In general , EEW will automatically puts the fields on the Screen. We donot want to worry abt that !
The generated BADIs can be implemented to do some Checks(for example) !
I hope this helps !
Thanks

SGD4.6 can't work with Java update7.51

SGD4.6 can't work with Java latest version update 7.51. The webtop keeps showing "loading", is there any patch for this issue?
When Java released update 7.21, it also can't work with SGD4.6, then Oracle fixed it by updating a patch, so how about this problem?

Have a look at this Thread:

How to Work with Composite Primary Key

Hi All,
I'm working with Toplink JPA. Here I have A problem with inserting into database table which have composite Primary Key.
What I'm doing is, I have two tables. to maintain many to many relation between these two tables I created another intermediate table which consists of foreign Keys (reference) of above two tables.
Now these two foreign Keys in the Intermediate table made as composite Primary Keys.
When I'm trying to the data in the Intermediate table I'm getting the foreign Keys values are null..
could anyone suggest me how to work with composite Primary Keys
Thanks,
Satish

I have the same problem, I have 3 tables with a join table joining them all. I have created an intermediate table entity. When I go to create a an entry, it says that I cannot enter null into "ID". Here is the SQl toplink generates:
INSERT INTO Z_AUTH_USER_AUTHORIZATION (CONTEXT_ID, AUTHORIZATION_ID, USER_ID) VALUES (?, ?, ?)
bind => [null, null, null]
Here are the classes:

I have tried to create the new entity several ways. I have tried to create one with the default constructor then set this entity on each of the other entities, I have also tried to pass in the entities to the join entity and set them there, but this doesn't work. Any help would be very appreciated!
Thanks,
Bill

What is Object Orientation?
Object orientation (OO), or to be more precise, object-oriented programming, is a problem-solving method in which the software solution reflects objects in the real world.
A comprehensive introduction to object orientation as a whole would go far beyond the limits of this introduction to ABAP Objects. This documentation introduces a selection of terms that are used universally in object orientation and also occur in ABAP Objects. In subsequent sections, it goes on to discuss in more detail how these terms are used in ABAP Objects. The end of this section contains a list of further reading, with a selection of titles about object orientation.
Objects
An object is a section of source code that contains data and provides services. The data forms the attributes of the object. The services are known as methods (also known as operations or functions). Typically, methods operate on private data (the attributes, or state of the object), which is only visible to the methods of the object. Thus the attributes of an object cannot be changed directly by the user, but only by the methods of the object. This guarantees the internal consistency of the object.
Classes
Classes describe objects. From a technical point of view, objects are runtime instances of a class. In theory, you can create any number of objects based on a single class. Each instance (object) of a class has a unique identity and its own set of values for its attributes.
Object References
In a program, you identify and address objects using unique object references. Object references allow you to access the attributes and methods of an object.
In object-oriented programming, objects usually have the following properties:
Encapsulation
Objects restrict the visibility of their resources (attributes and methods) to other users. Every object has an interface, which determines how other objects can interact with it. The implementation of the object is encapsulated, that is, invisible outside the object itself.
Polymorphism
Identical (identically-named) methods behave differently in different classes. Object-oriented programming contains constructions called interfaces. They enable you to address methods with the same name in different objects. Although the form of address is always the same, the implementation of the method is specific to a particular class.
Inheritance
You can use an existing class to derive a new class. Derived classes inherit the data and methods of the superclass. However, they can overwrite existing methods, and also add new ones.
Uses of Object Orientation
Below are some of the advantages of object-oriented programming:
Complex software systems become easier to understand, since object-oriented structuring provides a closer representation of reality than other programming techniques.
In a well-designed object-oriented system, it should be possible to implement changes at class level, without having to make alterations at other points in the system. This reduces the overall amount of maintenance required.
Through polymorphism and inheritance, object-oriented programming allows you to reuse individual components.
In an object-oriented system, the amount of work involved in revising and maintaining the system is reduced, since many problems can be detected and corrected in the design phase.
Achieving these goals requires:
Object-oriented programming languages
Object-oriented programming techniques do not necessarily depend on object-oriented programming languages. However, the efficiency of object-oriented programming depends directly on how object-oriented language techniques are implemented in the system kernel.
Object-oriented tools
Object-oriented tools allow you to create object-oriented programs in object-oriented languages. They allow you to model and store development objects and the relationships between them.
Object-oriented modeling
The object-orientation modeling of a software system is the most important, most time-consuming, and most difficult requirement for attaining the above goals. Object-oriented design involves more than just object-oriented programming, and provides logical advantages that are independent of the actual implementation

How to work with DTR and CBS?

Hi
I have designed one web dynpro application. Now I want to work on this application through DTR. Means i want to do versioning and all. How to work with DTR..? I have gone through lot of blogs and help available in SDN but i am unable to understand how to work with it.
One more thing how to work with CBS. How to configure CBS. I have NWDS latest version 7.0.7. In window perspective i am unable to find JDI. can any one please explain me if u have worked on this with example
If possible can any one send me the screen shots how to work with these ?
Best Regards
Ravi Shankar B

Hi Ravi
For you to work with DTR and CBS, firstly u will have to configure JDI on server.
To configure the NWDI, please go through the links given below:
http://help.sap.com/saphelp_nw2004s/helpdata/en/07/f6bc3d42f46c33e10000000a11405a/frameset.htm
http://help.sap.com/saphelp_nw2004s/helpdata/en/71/0369404c65587ee10000000a155106/frameset.htm
http://help.sap.com/saphelp_nw2004s/helpdata/en/43/26b84d6c823f66e10000000a11466f/frameset.htm
In Nutshell, following steps will be performed:
1) logon to Portal Devinf.
2) click on CMS
3) Go to landscape configurator
4) create domain
5) create tracks and add Software components in that track
6) runtime systems ( dev/qa etc are configured
7) in the transport studio, all the files listed are checked in through check - in tab.
8) they move to developement tab.
Once all these things are done, in your NWDS:
1) Setting the devbox host name and server port in Window -> Preferences -> SAP
J2EE Engine
2) Setting Portal URL in Window -> Preferences -> JDI -> DC Pool and ping server,
to check whether server is getting accessed from NWDS.
3) Once server is set, login to DTR and go to DTR perspective. Create a client there, by doing a right click and filling up the required details.
4) In the DC perspective, in the Local DCs view, perform import configuration.
5) the dev track is not configured
6) Under this, after logging into DTR, now you can create your project, check them in and create new versions.
Thanks & regards,
Anupreet

Itunes not working with 64 bit operating system

Does anybody know how 2 or when itunes will work or can work with a 64 bit system. I had no problems when I first downloaded itunes on my computer about 4 months ago. Then I updated itunes and it doesnt install properly. On the disclaimer it says it will only work with a 32 bit or less. I've lost my entire itunes library. atleast its still in my ipod but i cant burn any songs either. Does anybody know how 2 fix this?

If you are referring to Vista Support, It may be after the new year before it fully supports vista. I have not upgraded to vista yet but I was thinking about it!

Question on how networking works with new Macbook Pro

Hi,
I have a question about how networking works with my new Macbook Pro. This is my first laptop so am new to mobile computing. I am about to configure it to replace my desktop which uses a wired DSL connection. Once I have my Macbook Pro configured to run off the DSL modem, what happens when I take this computer to a location that has ethernet? Will just plugging in the ethernet cable be enough to get on line? Or is there further configuration work that needs to be done?
I used a Windows laptop from work and all I had to do was plug it in to a hotel ethernet cable to get on line. However, this laptop was never configured to run on my DSL network so I am not certain if that makes things more complicated.
Thanks for your help!

Hi
Your MacBook Pro should just work when plugged into an ethernet connection.
Just check something, Open Network Preferences, you can select it from the Airport icon in the menu bar.
In the left-hand pane click on Ethernet and just check that it is set to configure using DHCP in the right-hand pane, that's it.
So when you plug in the ethernet cable it will ask the router for an IP address and off you go.
I assume that any system you plug into will use DHCP rather than static IP addresses. If it is a static IP address, you will need to manually configure the ethernet settings by inputting the IP address and subnet mask info plus DNS servers.
Usually it is done with DHCP and you don't have to do a thing and likewise your home DSL is DHCP?
If not then you will have to change your settings, make a 'Hotel' setting which you can use when in hotels and keep your 'Home' set-up for when you are at home. In the pull down menu select Edit Locations to add new ones.

Who works with java?

A friend of mine was telling me how just about every app the isp he works for is designing lately, they've been doing in java. Now this got me curious because I havent' seen much on java for the past year. I'm just curious, if you work with java, what kind of apps do you tend to create with it?

Java is pretty much the top language for server side applications, I think because of its high quality threading (it can serve many clients easily). It also seems to be the language of choice for all business applications lately. But that's just because some idiots in a suit heard the name 'java' and decided it was cool, IMNSHO.
You probably haven't heard much about it because a) Its not overly popular for desktop programs yet b) the apps that use it just use it without bragging about it and c) its not overly popular in open source. But it seems to be getting bigger.
To answer your question about what kind of apps I personally create, check the signature.

JSR 296 - How to work with arguments?

Hi Everyone,
I am developing an application by using a JSR 296 Swing Application Framework but I don�t make any idea about how I could manage a line-command arguments.
Should I try through Application.getInstance().getContext().getResourceMap() or something like that?
My intention is to get access to arguments within the method startup(). However, note that they are not directly available for use unless I create a array member and explicitly assign them to this new member (I suppose it must have a suitable way for doing this instead of I mentioned):
I am using Netbeans 6.0 beta 1 to create this application, under the option File < New Project < Java Desktop Application
See below a snippet. As you can see, I would like to get a value of the first argument passed by user from line command.
    * Main method launching the application.
    public static void main(String[] args) {
        launch(MyApplication.class, args);
    @Override protected void startup() {
        // here I would like to access the arguments
        String firstArg = ?
        // show main frame
        show(new MyApplicationView(this));
    }Does anyone know how to make it possible?

How to work with 360 video?

I am new to AE and am trying to work with a 360 equirectangular video I shot with a Freedom 360 and 6 go pros.
Are there any tutorials on how to work with 360 spherical videos? Do I need to download additional plugins?
Thank you,
Phil

Phil,
Of course, the image needs to be big for this, but the plugin you would use is CC Sphere.
Drop your movie into a composition and apply CC Sphere to the video.
Then set the Render option in the effect to "Inside".
Under Shading set Ambient to 100% and Diffuse to 0%.
Then scale inside the effect until the image fills the screen.
Then you'll be able to use the Rotate Y controls in CC Sphere to spin around inside your video!
You can also add Optics Compensation and Reverse the Lens Distortion to straighten out your image.
Let me know if you have any questions!
