CRUD application
I have defined a entity and a session bean.
Now I want to maken a enterprise application client or desktop (what is the difference??) which can perform CRUD operations using the session bean.
I can't find anywhere how to do this job.
Please help me out.
thanks,
I think the URL given by Jagan_ayans does it all. You can only change the implementation from strut to Swing. If you guys want a generator, Check out the application CRUD table-like generator that is in NetBean 6.0.
Even with the generation, you will still have to tweak code to suit to case. Using a custom JTable will be best. I am sure to what I just said.
Currently, we are doing a JSF CRUD implementation where everything goes from database -> Entity EAOs -> Session Beans -> Managed Bean -> JSPs and what Jagan_ayans provided in the link is something close to it.
So, it is all possible.
>
There are lots of tools. Unfortunately, it's still not possible to push a button and have an app come out.
Lots of managers would love to have such a thing so they could fire all the programmers and have secretaries or drunken monkeys write enterprise apps, but we're not there yet.
Duffymo, you should know that no matters what modern day code generator generate, they will never suit today's complex business needs. There will always be a need for you (programmers). Think about the SQL, as human like the langauges seems to be, it has never been easy for a non-DBA or non-Developer to speak it.
We will always be in vogue.

How to create CRUD application using bapi in webdynpro java

Thanks in advanceHi,
Hey tell me one thing your BAPI having CURD methods. See you are getting data from BAPI and pull the data in Table in WDJ. So if u can do any action it will comes trough BAPI.
If your BAPI having CURD methods. You can implement CURD methods in WDJAVA also.
@ You said you are getting null values from the database. Please let me know what code you have to wrote for CURD. Please tell me.

Anyone know how to gernerate CRUD applications with flex and coldfusion?
Anyone know how to gernerate CRUD applications with flex and
coldfusion? I am working with a remote coldsfusion installation
with MS SQL and I don't have RDS.You might investigate "squidhead". It is CF based. I'm not
sure if it has any Flex related features.

SAPUI5 CRUD Application using OData
Hi Everyone,
Trying this tutorial here Building a CRUD Application with SAPUI5 Using Odata Model. Just wondering if anyone has tried using SAP's Gateway demo services (SAP Netweaver Gateway Demo System) in this tutorial. Or do we really have to create our own bank service.
Thanks.Hi,
As of now I did not tried POST/PUT on demo service. I did GET earlier.
you can first check if POST/PUT operation can be possible with GW Demo services. try with Demo service ZGWSAMPLE_SRV
As per this document, I guess it should be possible and then find out if bank service is available and then perform CRUD operations.

Flex 3 missing Coldfusion CRUD
I just installed Flex 3, and I get RDS working fine. I was
going to quickly build an app to test using the Coldfusion CRUD
Wizard, but it appears to be non-existent in Flex 3?
Help! Where did it go? Am I missing something? The only thing
I found was a CFC wizard on the the RDS Dataview tab, but I need
the entire CRUD application wizard, not just a few CFCs.
Thanks!This appears to be a bug in the Windows Vista x64
functionality with Flex 3 (even when the program is run as
Administrator). I have posted a bug report and the work-around I
discovered here at Adobe's Flex Bug and Issue Management System:
https://bugs.adobe.com/jira/browse/FB-12276
In case the link above becomes invalid, the problem is that
NONE of the Wizard Folder expand to show and of the wizards
available in the Wizard Selection window when you click to expand
any folder and show its contents. The work-around is to type part
of the name of the particular wizard you want to run in the search
field above the wizard folder listings. This will cause the folder
to expand and reveal the wizards matching what the user has typed.
In my case I had to install Flex 3 on my Windows XP system to know
the names of what I was searching for, and typing "cold" brought up
the ColdFusion CRUD wizard below the folder. -
New to programming. Should I use Flash Builder 4.6 to create CRUD interface to MySQL?
Having just acquired Creative Cloud subscription, I see that I have access to Flash Builder 4.6 Premium. I haven't figured out yet if I will eventually have access to Flash Builder 4.6 for PHP when / if it is released.
I am relatively new to programming. I want to create a desktop application, perhaps a web application, to manage a MySQL database. I am not, at this time, concerned with mobile applications. I'm primarily interested in just managing the MySQL data -- CRUD (create, read, update, delete) operations.
Hopefully I've provided enough context. My question concerns whether learning Flash Builder 4.6 and Flex programming is an appropriate choice. Alternatively, I could just focus on learning basic PHP programming or perhaps learning to use one of the PHP frameworks (CakePHP, CodeIgniter, or Zend). It seems like learning these frameworks will take time as well, so I don't know where I should begin.
I would really value your perspective. Are the Flash Builder related technologies here to stay? Is Flash Builder primarily suitable for mobile applications (rather than desktop or web)? Would it be more or less difficult to learn Flash Builder and Flex than PHP and one of the PHP frameworks with a view to building a MySQL CRUD application?
Thank you, so very much -- for your time and expertise.
KevinKevin,
I am a big fan of Flash Builder. You can build great desktop web applications as well desktop applications that run on AIR (installs locally to the desktop).
I found it easier to pick up Flex (now Flash Builder) primarily due to the resources (Learn Flex in a week video tutorials http://www.adobe.com/devnet/flex/videotraining.html ) as well as a big developer community that posts a lot of how to's and walk throughs. In my personal opinion, I think the power of Flash Builder/Flex framework is the ability to create what traditionally was seen as desktop apps within your web browser. If you're looking to create a basic crud interface, skipping Flash Builder and just doing it in PHP may be the way to go. If you're looking to add visualizations (ie graphs, charts) or highly interactive user interface to it then Flash Builder would be a good way to go (though keep in mind that you will still need PHP (or some other server side application layer like coldfusion) to interface with your mysql database but Flash Builder's dataservices creates some sample php classes for you to handle CRUD using Zend). There's lots of amazing things you can do with Flash Builder. I'd recommend checking out some of the samples from Tour de Flex to get a sense of what can be done with Flash Builder.
A couple of notes though - You can build and package native mobile apps with Flash Builder but if you're looking to create web apps for devices like iphone and ipads, Flash Builder isn't the solution since it compiles web based apps to Flash and we all know how idevices don't play nicely with Flash. -
ADF Bindings CRUD with either JDBC or Hibernate
Does anyone know of an example CRUD application that uses ADF Bindings and either Hibernate or JDBC.
The site...
http://technology.amis.nl/blog/index.php?p=765
uses ADF Bindings and Hibernate, but does not update a database.
I have attempted to do this myself, but when my add/edit page loads, all of my af:inputtext controls display labels instead of input boxes.
There are several ADF Biding examples for both Toplink and ADF BC, but if anyone can point me in the direction of examples for JDBC and/or Hibernate, I would appreciate it.I have created the target datacontrol for ADF Binding.
In my DataContorls.dcx file, my datacontrol (a JavaBeanDataControl, not an AdapterDataControl) has its SupportsUpdates attribute = "false".
When I create a form, the #{bindings.<my_property>.updateable} expression returns false, making it so my af:inputText controls cannot take input data. If I manually set SupportUpdates="true", my #{bindings.<my_property>.updateable} expression still returns false.
If anyone knows how to set it so I can make it so I can update my java objects, I think I will be set.
Any help would be appreciated. -

Are there any tutorials on how to build a CRUD application

Thanks!Neither. The Remote Authentication screen refers to hard-coded credentials in the CF server configuration as described here:

Warning this is very long code but i need help to see if I am on right trac
I have done all the following code myself and it is the buisiness layer for my application. I have tried to follow recommendations on previous posts and I would like to be told where I can clean up my code and how? This is not complete and it looks very long to me but I need help in order to be better. There are 4 button vlivks and I have not completed them all. The criteria for application is that phonebook will accept new entries if they have names surnames and phone numbers that are not longer than 10 characters for display purposes but can change this. No duplicates are allowed. No editing of a existing entry must lead to a duplicate entry either. No new entry or edit may result in a new contact having no phone numbers.
Many thanks for your time in advance,.....

How to create a new record using ODataModel?
Hi,
I am new to UI5 and so ODataModel. I have tied one table to an ODataModel.
How would I send request to a server so that I will have a new entry created at server end?
I googled this and I tried following:
1. Called createEntry method on ODataModel as follows:
sap.ui.getCore().byId("maintainRolesTable").getModel().createEntry("DERMASSIGNMENTSet",{
"DeUser":"C5192081",
"SeqNo":"X",
"Childbp":"C5192081",
"ChildbpName":"",
"Id":"2",
"RelationType":"",
"Parentbp":"I0656568",
"ParentbpName":""
2. I called then submitChanges method on the model as follows:
sap.ui.getCore().byId("maintainRolesTable").getModel().submitChanges();
This is giving error as follows:
POST https://lsftdc00.wdf.sap.corp:1443/sap/opu/odata/sap/ZSECENTRAL_SRV/DERMASSIGNMENTSet 403 (Forbidden) datajs.js:17
2014-06-05 16:53:32 The following problem occurred: HTTP request failed403,Forbidden,CSRF token validation failed -
When I try to use ajax call instead of these methods, I get error as follows:
var obj={
"Childbp": "C5192081",
"ChildbpName": "Supriya Kale",
"DeUser": "C5192081",
"Id": "8",
"Parentbp": "I0656568",
"ParentbpName": "",
"RelationType": "RESOURCE MANAGER",
"SeqNo": "1",
"metadata":{
"id":"https://lsftdc00.wdf.sap.corp:1443/sap/opu/odata/sap/ZSECENTRAL_SRV/DERMASSIGNMENTSet(DeUser='C5192081',SeqNo='x')",
"uri":"https://lsftdc00.wdf.sap.corp:1443/sap/opu/odata/sap/ZSECENTRAL_SRV/DERMASSIGNMENTSet(DeUser='C5192081',SeqNo='x')",
"type":"ZSECENTRAL_SRV.DERMASSIGNMENT"
$.ajax({
type: "PUT",
dataType: "json",
url: "https://lsftdc00.wdf.sap.corp:1443/sap/opu/odata/sap/ZSECENTRAL_SRV/DERMASSIGNMENTSet",
data: JSON.stringify(obj)
}).success(function( msg ) {
alert('HI read operation complete....................................');
}).error(function(msg){
alert("error occurred");
I get following error:
PUT https://lsftdc00.wdf.sap.corp:1443/sap/opu/odata/sap/ZSECENTRAL_SRV/DERMASSIGNMENTSet 403 (Forbidden)
Can anyone tell me if I am going wrong in calling methods? Help would be appreciated.
Thanks,
Supriya KaleHi Supriya,
you can take a look at this blog. Building a CRUD Application with SAPUI5 Using Odata Model
Scroll down to Create Operation.
There you can see that the author is also first fetching CSRF and the calling CREATE operation.
For simple example see correct answer in this thread.
HTTP request failed403,Forbidden,CSRF token validation failed

Noob needs help re offline desktop db app - is FB the right tool?
Hi,
Thanks in advance for reading, and being patient with my long-winded-noobiness!
I am a self taught (read as: big gaps in my knowledge!) independent web designer/developer, with experience in developing PHP/mySQL database web-apps - both with DW, and by hand-coding. I've been approached by a potential client asking if I could build a simple CRUD desktop application, and am trying to figure out if I can leverage my existing knowledge in doing so. It's something I know I could develop in a snap for the web, but I'm left realizing I don't know the first thing - or even where to begin learning the first thing! - about desktop software development. I'm hoping Flash Builder might be just the ticket for me (I'm not sure if the client will want to wait around while I learn JAVA!!), since I already own and am familiar with CS5. I've been going over all the documentation, tutorials, etc. that I can get my hands on, but am finding my brain a little overwhelmed and frazzled, so I'm hoping one of you wonderful folk might be able to offer a simple answer!
Can I use Flash Builder / Flex to develop a strictly offline, local desktop CRUD application, but one which connects to a (local) mySQL database (ideally with PHP, since that's what I already know) - without the end-user having to separately install a local server?
If not, any suggestions? As well as Flex, I've been looking into Java (but am finding the learning curve quite steep), and Filemaker Pro 11 Advanced (which allows you to create a runtime - but I'm finding it a bit restrictive, and would rather not have any Filemaker branding on the finished product),
In case you're wondering why I don't just convince the client to create a web-app instead, the data stored would be of a sensitive nature, and the main target demographic is baby-boomers, many of whom are still very wary of the interwebs
Thank you so much for any help you can offer!
Cheers,
DavidActually, I would think that Flex would be ideal using AIR with a SQLite database (the database is built in to AIR apps). However, if you've not done programming with Flex before, I won't trivialize the learning curve you have ahead of you. If you haven't already done so, go through Flex in a Week or get the latest Training from the Source for Flex 4 and get comfortable with the Flex workspace and programming environment. You'll like come to love it but it's a bit different than PHP. It would be an easier transition, I think, if you had a heavy background in JavaScript or Java so that you felt comfortable using OOP programming techniques. If you already structure your PHP programs with OO principles, it'll be an issue of getting used to the language and, if I were guessing, that might take you a month or two. That's my 2 cents worth.

Hello everybody, im a novice on Developpement using Flex.
im working on a project which will be runned on BlackBerry Tablet (PlayBook), im using FlashBuilder Burrito + AIR SDK

and i can't even find an error !! could anyone help me or even give me a solution to read the error report.
thx.so... while no one find the probleme or even give me an answer to it, i search another solution that correspond to my knowledge and i found : As-SQL it's easy to use and while u don't need to manage a lot of data this solution will be helpfull.

Hi,
I have a CRUD application.. Where in the data is fetched, displayed n edited n stored back to db. Also there is a sequential access between pages & the information entered on the first page is needed on the second page & so forth. What would be the best scope & why ?
When to use which scope? What is the life-cycle of each scope.
Also, I couldn't find any good tutorial on scopes. If you are aware of the same, please guide.
Its urgent.

Thanks in advance.You could use ViewScope and parameters to the next view or if using CDI have a look at conversation scope. You should read about them in detail yourself because even if someone chooses one for you it's still you who has to go on to use it correctly.
