UI and Application Code?

I've been exposed to Java but without GUI. I've just started to learn swing and event handling. Normally in developing an application, the GUI code and the application code is preferrably separated. Now my question is, how do the application code and GUI are able to interact. How do I connect them? inheritance? i hope to get some sample codes to do this. I've bought books to learn java but none seem to tell me how to...Hope to get some replies soon. Thanks in advance

See that link over at the left that says "Tutorials"? Click on it, it will lead you to a page full of links to guess what. One of those links says "The Swing Tutorial". Need I say more?

WLSS3.0 and application code SNMP trap error

Hi,
I'm trying to generate SNMP traps through application code as described in the documentation at [url http://e-docs.bea.com/wlcp/wlss30/programming/snmptraps.html]. By using an SNMP manager I have verified that WLSS can send traps during startup and shutdown. My application code, however, fails to do so. When my SIP servlet is deployed, I get the following errors.

Hi,
what you show us is not teh servlet mapping but the servlet definition. The servlet mapping maps a configured servlet to a URL. You can use the property editor in JDeveloper for this. Just select the web.xml file and choose "properties" from teh context menu

How old is this machine? If it's less than 90 days old you have 90 days of Free AppleCare coverage, call them! You will find the phone number in your manual. If it's out of AppleCare or you bought it used take it your local Apple Store or AASP to have it looked at. We don't have enough information to know what the problem might be. You can run some tests such as Apple Hardware Test in Extended Mode 2-3x to see if it has any hardware errors. Beyond that it's really tough to say.

Creating exe for application that contains ARINC and MIL Codes

Hi all,
I am not able to create exe for my application that contains ARINC and MIL. To be precise, the ARINC and MIL part is not working in the exe created.
Please tell me how to create an EXE with ARINC and MIL codes.

Did you install the according device drivers on the target machine? And no I don't mean the instrument drivers that you use in LabVIEW but the OS device drivers from NI (resp. AIT), that will access the hardware boards and provide an interface to the LabVIEW application. I would expect them to be part of the AIT SDK kit that comes with the boards.

What is the diffrence between sap events and application events

Hi all,
what is the diffrence between sap events and application events.Can any one tell me with examples.
regards,

Hi,
Look at this,
<b>System Events (Default)</b>
The event is passed to the application server, but does not trigger the PAI. If you have registered an event handler method in your ABAP program for the event (using the SET HANDLER statement), this method is executed on the application server.
Within the event handler method, you can use the static method SET_NEW_OK_CODE of the global class CL_GUI_CFW to set a function code and trigger the PAI event yourself. After the PAI has been processed, the PBO event of the next screen is triggered.
The advantage of using this technique is that the event handler method is executed automatically and there are no conflicts with the automatic input checks associated with the screen. The disadvantage is that the contents of the screen fields are not transported to the program, which means that obsolete values could appear on the next screen. You can work around this by using the SET_NEW_OK_CODE method to trigger field transport and the PAI event after the event handler has finished.
<b>Application Events</b>
The event is passed to the application server, and triggers the PAI. The function code that you pass contains an internal identifier. You do not have to evaluate this in your ABAP program. Instead, if you want to handle the event, you must include a method call in a PAI dialog module for the static method DISPATCH of the global class CL_GUI_CFW. If you have defined an event handler method in your ABAP program for the event (using the SET HANDLER statement), the DISPATCH method calls it. After the event handler has been processed, control returns to the PAI event after the DISPATCH statement and PAI processing continues.
The advantage of this is that you can specify yourself the point at which the event is handled, and the contents of the screen fields are transported to the application server beforehand. The disadvantage is that this kind of event handling can lead to conflicts with the automatic input checks on the screen, causing events to be lost.
Hope u understood.
Thanks&Regards,

Menu bar and application toolbar

is there a way to change item text on menu bar and application toolbar eg in business partner overview(T-Code fmcacov) i want to change text 'Business Partner" to "tax Payer" on both menu bar an application toolbar. i have tried the norma way of going to change the screen but when i am on the GUI status its not going to change mode even sfter entering the access key

Hi ,
Open the program and click on GOTO=>ATTRIBUTES.
Change the text to the heading which you want.
SAVE & ACTIVATE.
Regarding opening in change mode, the steps you have carried out are correct.
You need to comment the existing gui-status by placing cursor on that line & click delete.
Then click on INsert button and add new gui-status.

My phone does not show contact names for country and area code while having in coming calls. Although, I have endorsed the name with numbers. How do I the problem. My one is a iphone 3s device with updated os. Please text to help

My iphone does not recognize saved contact number while having incoming calls due to country and area code as auto prefix. How do i fix the problem. How do i ensure that the phone recognize calls with and without the country and area code. Please text to help.

1) Open the Phone and dial *228. This is a Verizon over-the-air programming number.
2) When the system answer press 1 for "Program or activate your phone"
3) Wait for the call to disconnect. You should get a prompt stating something like, "Settings updated."
4) Open the Task Manager and kill the Phone, Message, and Contacts Applications
5) Wait a few minutes (I waited 3 just to be extra safe)
6) Open the Message App to verify the fix

MVC model in Web systems and applications

MVC model in Web systems and applications
Object-oriented design model is experience, MVC idea is a user interface for the original. This article discusses how the major application areas in the new Web design patterns and the use of MVC framework. The article first introduced the concept of design patterns and characteristics, and MVC architecture design concepts and analysis of the MVC framework contains several key models. Based on the characteristics of Web applications on how to use patterns and MVC framework made some design ideas.??
1. Introduction
1.1 design model
Object-oriented technology and the emergence of software applications has greatly enhanced the trusted and software quality. Object-oriented programming than previous models to various programming simple and efficient, but the object-oriented design methodology than the previous design methods to complex and much more skill, a good design should be both on the issue of gender, but also to take full account of the problems and needs sufficient interoperability. In the past 10 years, people in the object-oriented technology and the practical application of research to explore certain issues in relation to the creation of a number of good solutions, the so-called object-oriented design patterns. Object-oriented technology is one of the purposes of enhancing the software trusted, and to design model, design programmes in important positions from a deeper sense of meaning and essence embodies trusted. There are many people in the design model definition, which cited Christopher Alexander is the largest design model definition : Each design model is a tripartite rule, which expresses a contextual environment (Context), a problem and a solution. Design models generally following basic elements : model name, the purpose solution effect 1995-1998 code and related design models. There are several classifications design patterns can be divided into a model based on the purpose (Creational), structural type (Structural) and the type of behaviour (Behavioral) three. It is mainly used in the creation of a model-based object model-based structure to deal primarily with the category or combination of objects, used to describe behavior-based model is the main target for the category or how stress and how to allocate responsibilities. Design patterns can be divided into categories based on the scope and target mode model type model dealing with the relationship between the categories and sub-categories, these relations through the establishment of succession in Translation moment to be finalized, are static. Model is targeted at addressing the relationship between the moment of change these relations in the operation, more dynamic. Model features : through the experience acquired in a structured format to write down, avoid encountering the same problems on the first design, exist in different abstract level, in continuous improvement, can be trusted artificial product for the design and best practice in the world to be combined to address larger issues.

MVC was first used in a user interface Smalltalk-80 China. M representative models Model, representatives maps View V, C representatives controller Controller. MVC trusted code with the aim of increasing the rate of data reduction expressed, the data describing the operation and application coupled degrees. Also makes software Keweihuxing, restorative, expansionary, flexibility and packaging of greatly enhanced. Single-user applications are usually incident-driven user interface to the organizational structure. Staff development tool with an interface painting of a user interface interface code based on user input and then prepare to implement the corresponding moves, many interactive development environment encouraged to do so, because it emphasizes first and then a functional interface. Some software design model is the strategy that will be fixed before the code into the regular system of the final. Result is that the procedures and organizations around the user interface elements in the user interface elements of those moves, data storage, applications and functions of the code is used to indicate the way intertwined. In single-user system code structure can be so, because the system will not demand frequent changes. But for a large system such as large Web systems, or e-commerce systems to be applied. Model by incorporating data from a variety of access and control data can be separated to improve distributed system design. MVC design pattern is composed of three parts. Model is the application object, no user interface. Type in the screen showing that it represents the flow of data users. Controller user interface definition response to user input, the users responsible for the action against the Model into operation. Model View data updated to reflect the adoption of data changes.
2. MVC design pattern,
An MVC framework for the design of the system includes many models, but with MVC is most closely related to the following three models : Observer, Cambridge and Strategy.
2.1 Observer models
MVC through the use of purchase / notification form and the separation of the Model View. View to ensure that their content accurately reflected Model and state. Once Model content changes, there must be a mechanism to allow notification to the relevant Model View, View can be made relevant at the appropriate time updating of data. This design is also more general problems can be solved, the target separation, making a change to the target audience affect others, which targets those who do not know the details of the object being affected. This is described as Observer in the design model. Model type : Observer model is the object-oriented model, it is behaviour-based model. Model purposes : definition of hierarchical dependence relations between objects, or when a target value of the state change, all its dependent relationship with the object are notified and automatically updated. There are a variety of data may show a way, in different ways and may also show. When a way through a changed data, then the other should be able to show immediately that the data change and do accordingly.
Effect :
1. Abstract coupling. I only know that it has a target audience of some observers, the observers met each abstract Observer category simple interface, does not know their specific affiliation categories. This makes the coupling between goals and observers smallest and abstract.
2. Support radio communications. Needless to notify designated observers goals, how to deal with the observer informed decisions.
3. Possible accidents updated. We update logic, avoiding mistakes updated.
2.2 Faculty model
MVC is an important feature of View can nest. Nest can be used for any type of combination of local maps available, but also management of type nest. This thinking reflects the type and mix of components will be equal treatment design. This object-oriented design ideas in the area of Cambridge has been described as a design model. Model types : Cambridge model is the object-oriented model, it is also the structure type model. Model purpose : to target portfolio into tree structures to express "part-whole" level structure. Prepared for the use and combination of individual target audiences with the use of consistency.
Effect :
1. Definition of a target portfolio includes simple objects and the structure of the category level. Simple objects may be complex combinations of objects, and can be targeted portfolio mix. This customer-code used in the target areas can use simple combinations target.
2. Simplify customer-code. Needless to know their customers - a mix of target audiences is a simple target or can use these items in a consistent manner.
3. Easier to add new types of components. New components can easily be changed to a combination of customer-targeted codes.
2.3 Strategy model
Another important characteristic is the MVC can not change the View of changes View response to user input. This often requires a change in response to the logic of the system is very important. MVC to respond to the logic involved in the Controller. Controller of a category level structure could easily change to the original Controller appropriate, a new Controller. View Controller son used to achieve a specific example of such a response strategy. To achieve different response strategy, as long as examples of the use of different types of replacement will Controller. Also in the running time by changing the View Controller for users to change View of response strategies. This View-Controller relationship was described as an example of Strategy design pattern. Model types : Strategy model is the object-oriented model, it is behaviour-based model. Model purposes : definition of a series of algorithms, and their packaging, and ensure that they can replace each other, making algorithms can independently use its customer-change.
Effect :
1. Strategy category levels for Context definition of the relevant algorithms can be trusted or behaviour.
2. Alternative methods of succession. If the direct successor Context, with different acts will be added Context act, the realization of which would algorithm mixed up with Context, Context hard to preserve and expand, but can not dynamically changing algorithms. Will be enclosed in a separate Strategy category algorithms to enable algorithm independent Context change easily cut over expansion.
3. Can provide the same acts different date.
4. Strategy-must understand what customers between different.
5. Context and Strategy communications between costs.
6. An increase in the number of targets.
3. MVC in Web application system
Now some of the distributed systems such as Web-based B2B e-commerce system, suitable for use MVC framework. Through analysis from the perspective of high-level applications can be a target divided into three categories. Category is shown for the target audience consists of a group of commercial rules and data, there is a category that is receiving requests to control commercial target to complete the request. These applications often need to change is shown, such as web style, color, but also need to demonstrate the contents of the display. And the business rules and data to be relatively stable. Therefore, said that the frequent need to change the View objects that the business rules and data model to be relatively stable target, and that the control of the Controller is the most stable. When the system is usually issued after the View objects by artists, designers or HTML/JSP system managers to manage. Controller target applications development personnel from the development and implementation of rules for commercial and business development personnel from the target data, database managers and experts in the field of common completed. Show in Web?? or customers - control logic can be Servlet or JSP, dynamically generated Html. Generally used Servlet better than using JSP. JSP will be better with the Html code of separate codes for page designers and developers of separation efficiency. Servlet and JSP can complete all complete functions, actually JSP eventually converted into a Servlet. And control of the target system exists in every level, the coordination of cross-layer moves. Contain business rules and data objects exist in the EJB layer (EJB-centred model) or Web?? (Web-centred model).
3.1 View in the Web application system
View of the system shows that it fully exist in Web??. General by JSP, Java Bean and Custom Tag. JSP can generate dynamic web content using Java Custom Tag easier Bean, but it can show the logic of packaging, and more conducive to modular trusted. Some well-designed in a number of JSP Custom Tag can even be used in different system duplication. Model for control of JSP and Java Bean objects. JSP through Java Bean objects to retrieve the data model, the Model and Controller object is responsible for updating the data on Java Bean. In general, can we devise all possible screen that users can see all the elements of the system. Based on these elements, to identify the public part of passive components and dynamics. Can consider the use of templates means to separate the content generated JSP public, also need to change their generation Html or JSP from a JSP templates to dynamically introduce these different parts (include methods). Another issue to consider is screen option, when dealing with End users request template automatically available to show that the concern that users must know what is the screen components. So can consider all screens on the definition of a centralized document, such as a document or text document java. Taking into account the possibility of changes in future document definition screens, the best use of text documents such as a XML document, so future changes to the recompilation. According to the URL and user input parameters to shine upon the results of a screen, of course, likely to be made on the basis of the outcome of the implementation of actions to choose different results screen. Therefore, the need for a request for matching resources with document (XML), if a URL request several different results, it must specify in the document need to control the flow (a controller object), as well as the corresponding screen different flows.
3.2 Model in the Web application system
Model objects represent business rules and business data exist in EJB layer and Web??. In J2EE norms, the system needs some data stored in the database, such as user account information (account model), the company's data (company model), some not recorded in the database. If a user browsing the current catalogue (catalog model), the contents of his shopping (shopping cart model). Which one of these models exist in the data according to their life cycle and scope to decide. In Web?? a HttpSession and ServletContext and Java Bean objects to store data in the EJB layer is a data storage and logic EJB to. Web?? the Java Bean objects stored in the model layer model of the EJB object data copy. Because there are many different EJB tier model targets, so Web?? through a ModelManager to control the EJB layer object model in ModelManger background model can be used for packaging methods. In the EJB layer and the rules have all the data into EJB model is inappropriate. If the database can visit the Dao object model into objects. Dao can be encapsulated and the specific details of the database in the world, if we can write a different table, a number of databases, or even multiple databases. If the orders can be a model for OrderDAO, it may have to deal with Order table, table and OrderItemLines OrderStatus table. Value can also consider the use of targets. Value can be a target of securing long-range targets, because every time the remote object attributes could be a long-range redeployment process will consume network resources. EJB objects in the distance can be used instead target. In the distance, one-time items to be targeted instead of the value of all attributes.
3.3 Controller in Web application system
Coordination with the Model View Controller object to the request of users into the system to identify incidents. In Web?? generally a MainServlet (or Main.jsp), and receiving all requests, it can use screen flow management devices (ScreenFlowManger) decided next screen. There is a general request processors RequestProcessor contains all requests are needed to be done to deal with logic, such as the request translated into system events (RequestToEvent). Acting processors usually also includes a request for ClientControlWebImpl, it is logical to deal with the EJB layer in Web?? Acting. In EJB layer, a layer for EJB tier Web ClientController provide the CD visit. Another StateMachine used to create and delete ejb handle Web?? sent to the incident. Controller Another important function is synchronous View and Model data. ModelManger contained in a ModelUpdateManger, it puts events into a Model System assembly that all the needs of synchronous Model, and then notify Listeners do synchronous operation.
4. Concluding remarks
In recent years, with the Internet technology development and the emergence of new business models, the Web is based on a large number of applications. On how to design these systems architecture, and gradually there has been some convergence of opinion, the most important point is that its structure should be rational in the open. Demand than ever faster development of technology and design concepts, systems for the future, the cost of upgrading the smallest, research software systems architecture still very useful and necessary.

Bravo. And your point is?

Oracle.jbo.NoDefException: JBO-29114 ADFContext is not setup to process messages for this exception. Use the exception stack trace and error code to investigate the root cause of this exception. Root cause error code is JBO-25058. Error message parameters

Dear Guru's,
I am not able to solve the above issue for last couple of days.
I am newbie to the webservice
My Issue...
I am using Jdeveloper 11.1.2.4.0 Release 2
1. Using Jdev I built one small Web Service with two methods.
        While testing the Webservice...
               I passed User Id as Parameter and it successfully return the values (user id, user name and description) from fnd_user table
2. I created another application to consume the web service i created.
               1. I added the webservice SOAP and added the method.
               2. Created a jsf page and drag and drop the parameter and return values to the jsf page.
3. While executing the created jsf page I received the error message as below
"oracle.jbo.NoDefException: JBO-29114 ADFContext is not setup to process messages for this exception. Use the exception stack trace and error code to investigate the root cause of this exception. Root cause error code is JBO-25058. Error message parameters are {0=Attribute, 1=UserName, 2=UserName}"
Even I know that this issue is repeated one in our forum, I was not able to solve this issue.
Can anybody help to solve this issue.
Thanks and Regards,

How to find out what are the interfaces used for Job and Job Codes

HI All,
I just wanted to know how do we find out what are the interfaces used for Job and Job codes .
Thanks In Advance
Sunny

Hi,
Here is an idea for your request.
Basically you can create a simple query on multiprovider 0TCT_MC01.
Filter: you can use a variable for restriction of time ( calday, or calmonth) since you should be interested for a time period.
Choose following characters into your objects:
InfoProvider ( 0TCTIFPROV ) - you can create a variable for choosing infoprovider before query runs.
*Tp.[Type of BI Application Object] 0TCTBISOTYP = filter this with 'QUERY' or whatever your need is.
*BI Application Object 0TCTBISBOBJ, ( this will give you the name of the queries)
In key figures choose, Count for BI Appl. (0TCTWTCOUNT).
(number for query run)
Create a condition , for top 20.
Hope this helps.

OS X and classic creator and type codes

Is there anyway, within the native os to change type and creator codes?
Why would I want to? Here's an example:
I get a .zip from a customer. Because I have Stuffit installed it takes ownership of the archive. That would be fine except I've noticed different results using stuffit vs. BomaArchive helper. As in they don't unzip with the same amount of files.
I used to use Super Get info to change them, but that's not a possiblity now. And if Apple didn't hide Boma so deep in the OS I might be able to just make an alias and drop them on it. Won't find on a search for "Boma", both visible and invisible.
Thanks for any help. I'm just trying to find another way to make my OS do what I want it to, not what some app develper or OS creator deems should happen.
Remember... think different?

You can easily change any document's default application by selecting the document icon, press COMMAND-I to open the Get Info window. In the section labeled Open With select the desired default app from the drop down menu. If you want all similar documents opened by the default app, then click on the Change All button.
Alternatively download the freeware preference pane RCDefaultApp from www.versiontracker.com.
BTW, not pointing a finger at you, but keep in mind that even morons "think different."
Thanks for your ideas, and more, thanks for the jab at the slogan Apple used to use to differentiate itself, and it's consumers from other, less user friendly OS's.
But your solution doesn't help me. I'm well aware of changing the assigned app through the get info window, and that there are other utilities as, if not more adept at this function. My problem is that, if I have to solve my problem this way, instead of gaining knowledge about what effect type and creator codes have in OS X and how to change and deal with them, I find it hard to impossible to track down the location of the app BomaArchiveHelper. It never appears in the "Open with" pop up, and therefore I need to know the location in order to navigate to it to tell OS X to use it. And being that I see different results when unzipping depending on which app was used to create the zip, I don't want to set it as default.
So, my questions stand.
How do you view and alter type and creator codes in OS X, and where exactly is BomaArchiveHelper located.

New Note 790189.1 - Oracle Clusterware and Application Failover Management

Hi all,
please, note the newly created Metalink Note 790189.1 - Oracle Clusterware and Application Failover Management if you want to use Oracle Clusterware as a general purpose cluster solution. The note intends to clarify and to explain the current situation in regards to the supportability of applications managed by Oracle Clusterware.
In environments not including Oracle RAC, Oracle Clusterware still provides the level of high availability that is commonly known to be achievable for applications and databases managed in (failover) cluster environments. These environments can include Oracle Single Instance Databases, Oracle Application Servers, Oracle Enterprise Manager components, third party databases, or any other kind of application. (For more information on Oracle Clusterware 11g in general, please, refer to [Oracle Clusterware homepage|http://otn.oracle.com/clusterware].)
Metalink Note 790189.1 - Oracle Clusterware and Application Failover Management is tightly integrated with the information on application failover management available on the [Oracle Clusterware homepage|http://otn.oracle.com/clusterware] and discusses typical questions like
* Terminology
* Script supportability and preconfigured agents
* How to prove that action scripts work outside of Oracle Clusterware
* Supportability of the Oracle Database Single Instance example scripts
* How do I know whether a certain script is supported as a preconfigured agent?
Metalink Note 790189.1, however, does not change the level of support that has been introduced for these kind of configurations as of Oracle Database 10g Release 2: "Generally, Oracle does not support action scripts in the strict terms of supporting individual code fragments. Oracle fully supports the integration of individual action scripts proven to run outside of Oracle Clusterware into the Oracle Clusterware management stack. Supported operations therefore typically involve crs_* commands such as crs_profile, crs_register, crs_setperm, crs_getperm, crs_start, crs_stop, and crs_relocate invoked on custom resources. If actions scripts are used as part of a preconfigured agent, Oracle or the application provider who provides the agent will support the integration of this agent, while only the application provider will provide support for the individual action scripts."
Just for your information. Thanks,
Markus
