Master-detail applications using EJB

Has anyone tried to develop any? If so, what controls did you use to display the detail records? I have tried with JTable but with no result. I'd appreciate any help.

This question seems off topic for this forum. Perhaps you could post this in a more appropriate forum like the swing or awt forum. Thank you.

Question on "Master Detail page using ADF" sample

I downloaded the "Master Detail page using ADF" sample application. I modified editDepartment.jsp page to include the Commit button as follows:
<html:submit property="event_Commit">Save and Commit</html:submit>
When I go to edit a department record and click on the new "Save and Commit" button, I SQLed the DEPARTMENTS table and noticed that the edits were not commited. I also restarted the embedded OC4J server and still get the same results. For some reason, the department view object contains the modification but the entity object doesn't. Why?

Scott,
My colleague suggested a workaround, which is to explicitly include the detail table's id in the master table's partialTargets list. So, for example, in MasterDetailDP.uix, changing:
<table model="${bindings.DepartmentsView1}"
       id="DepartmentsView111"
       partialRenderMode="multiple"
       partialTargets="_uixState">to:
<table model="${bindings.DepartmentsView1}"
       id="DepartmentsView111"
       partialRenderMode="multiple"
       partialTargets="_uixState EmployeesView312">...will cause the detail table to be updated when sorting the master table.
There is some question about whether sorting a table should actually cause the currently selected row to change - we're still discussing this point.

Lock Master-Detail Application

Hi, I've created a Master-Detail application. I need to do, that after its saved the user cann't insert datas any more. The same application must say it. I need to do that when I do a query with the module, so that; when the user use CTRL + F11, after he cann't insert datas.
My application let to insert a data in the master, several in the detail and after saved it, it shouldn't let to insert datas.
I'm using Designer 10g.
Thanks so much.
Angel

I don't think I understand your requirements completely, but I think you need to add code like set_block_property('<Blockname>', insert_allowed, property_false) where you want to disable the insert.

Master Detail Application

Hi,
We are extending a standard fiori application. It is a master detail screen application. On action of a button in master screen, I need to send the model data to the detail screen.
What is the approach I need to follow to acheive this functionality.
Regards
V

Hi,
As long as you created the Master/Detail pages using the page wizard, the relationships and settings should all be set up for you.
When you create a new Master record, there will be no child records at that point. If you click Create, the Master record is created and the Detail report is refiltered to display any record related to the new Master record - but, as it is new, there are no Detail records, hence the message. If you click the Add button now, you can create new Detail records.

Master-Details Application

Hi,
There are many treads about Master – Detail wizard using two or more details table. I built a demo application on http://htmldb.oracle.com/pls/otn/f?p=26372.
This application is a demonstration using Master Detail wizard, views, and popup pages. “Emp Address Detail” region is based on a view, which is constituted of two tables.
One should build a view according to the business logic.
Click on “Demo for Master-Details” on Navigation menu.
Suppose that there are relations One to Many between one master and two or more details tables.
One can use two regions on a page. First should be a form region for the master table and second one should be a report region with several links.
1.1. Create a view of those two or more details tables. That is one master and one details view.
1.2. Create a Master Details form. The details form should be one of details tables.
1.3. Go to Edit Region (Details Region) and change SQL Query (updatable query) to SQL Query.
The Details form became Details Report.
1.4. Change Report Region Source from details table query to the view query.
1.5. Duplicate columns which are links and reorder them. Replace their header names with “ ” for instance.
1.1. Into Column Attributes/Column Link/Link Text pick an icon.
1.7. Select for Attributes/Column Link/Target “URL” for table Emp_Address and into URL field type:
javascript: popupURL('f?p=&APP_ID.:1003:&SESSION.::NO:1003:P1003_ID:#ID_ADDRESS#','Link','scrollbars=yes,resizable=yes,width=625,height=350,left=25,top=150');
1.8. For Emp_Course table select Attributes/Column Link/Target “Page in …” and type 1004 for instance.
Now the page has one form with Next and Previous buttons for the master table and one report for the Details view with two or more links. Pop-up window with an edit detail table form appears when one click on a link (icon).
Konstantin

I think this is the same problem I am having.
I have 2 pages: page1 is a simple report
page2 is a master-detail form
on Page1 a column is a link to page2
Everything at first seems to be working untill I click
on the create button on the master-detail report to create
a new master record, the master report disappers.

How can I develop a web application using EJB design pattern?

I have searched over the web and found quite a lot of tutorials on how to use the EJB design pattern.
I know that there will be a home interface, EJB object interface and a SessionBean.
But the tutorials often only cover a single class, this made me unable to get a complete picture of how EJB design pattern can be implemented into a whole system.
I am now required to devleop an online shopping web application using EJB and JSP page.
I think I will need to create a lot of classes: Member, ShoppingCart, Product...etc.
What I want to ask is that, do I need to create a home interface, EJB object interface and a SessionBean for each of these classes?
I really need some ideas on how to develop this system using EJB + JSP pages.
Many thanks to you all.

For every EJB that you want to create, you will need to code a home and remote interface and a bean class.
You could start getting your ideas here

Master-detail dropdown using selectonechoice

I have a master-detail releationship between 2 views that I want to display as one table (master) with the detail as a selectonechoice dropdown list column in the master table. The example in "Not Yet Documented ADF Sample Applications" no 71 "Dropdown Lists in Table with Different Choices per Row" explains a method for doing this but it involves querying all the detail records and then using the foreign key in the master to filter the rows in memory, which is not efficient for a large detail view.
Is there a better way?
Hugh Nelson

I think you'll need to use an af:foreach inside your dropdown list components to list the details for each master.

Can you create master-detail output using a PDF template?

My starting point is a pre-designed PDF template for producing purchase orders. This has a fixed background containing graphics and text. Over this I have overlaid the required fields and in the PO line section have defined a repeating group.
This works correctly only if the XML input file contains one and only one PO. If I want to produce multiple PO's (and I do) then is there a way to nest the repeating groups so that for each PO a new header is printed followed by the lines, i.e. a standard master-detail report? This is promised in the "XML Publisher Business Applications" powerpoint :-)
I know this can be done using an RTF template, but I have not found a way of fixing the positions of all the boilerplate text/graphics, as required, using Word. (The final section, which contains additional "header" information gets pushed down the page as PO lines are added.)
Any help gratefully received.

That depends.
Are they asking you to put a copy of your actual signature on there or are they asking for a "digital signature"?
They are different things.

Visualize master-detail relationships using SQL Edge 1.2

SQL Edge 1.2 released by Bay Breeze Software (http://www.baybreezesoft.com) is an Eclipse Rich Client application that allows users to execute SQL queries, browse schema information, and visualize master-detail relationships.
With SQL Edge, users can use only one query to retrieve data in a master table, and then browse data in all related detail tables. Users can also insert, edit, and delete table records in the data grids.
SQL Edge has four perspectives. The Query Perspective allows users run any SQL queries, while the Schema Perspective displays table schema information. There are two relationship perspectives. The Relationship Table View displays data in the master-detail style. The Relationship Tree View displays master table records as top-level tree nodes. The nodes can be expanded to reveal any level of related detail records. In addition, clicking any node will display the corresponding data in a detail grid.
The following summarizes SQL Edge's major features:
(1) Support any JDBC compatible databases.
(2) Allow users to specify JDBC drivers at run-time, and provide wizards to help setup JDBC connections. Easy to install, and easy to setup.
(3) SQL editor with syntax highlighting based on currently connected databases.
(4) SQL edtior allows users to execute SQL queries asynchronously. Users can cancel the execution by click the "Cancel" button or just close the SQL Editor.
(5) Schema perspective displays the table schema information, including column definitions, primary key, indexes, and foreign keys.
(6) Relationship table view displays the related data in master-detail style, with master table data shown in the top grid, and all related detail table data in a list of bottom grids.
(7) Relationship tree view displays the master table records as top-level tree nodes, and the related detail records as child nodes. Click any of these tree nodes will display the corresponding record data in a detail grid.
(8) Allow users to insert, edit, and delete records in the master and detail grids of the relationship table view and relationship tree view.
(9) Allow users to define master-detail relationships even between tables in different databases. This enables the relationship table view and relationship tree view to display data relationships between tables in different databases or without pre-defined foreign keys.

Hi, Martin.
Maybe you don't need a master detail relationship. Do you need to do changes in your detail block, or just queries?
If just queries, you can create your second block based on a From-Clause Query, and change the QueryDataSourceName property with a When-List-Changed trigger in your T-List.
I know this is a little vague but, without knowing what you need to do in the second block, I'm afraid to tell you more.
Feel free to mail me directly, if you need some pointers about Forms.

Creating master details application with views!

Hi All,
I have a requirement to create the master details with the views, but when I was trying to create the master details its asking me for Master Table name & detail table name. Here I am giving the master table name in place of detail table name I am using view but its not showing my view in query builder, my view is already there in the database
any idea why its not showing my view?
Thanks,
Suma.

Hi Claudia,
I am so sorry, but I do not check the Oracle forums every day. I am under presser, because have to relocate from Bulgaria to the USA through the end of November.
Shortly, any view could be updatable under many restrictions. I suppose, that is the reason for the errors. I don’t know what kind of connection you have between those two tables.
Under all these circumstances, I’ll offer you to build first a form on the base of the first table which all columns are used. Then you can test, refine, and finish all details about it.
Second, you can Create Page Computation retrieving the column (value, if any) from the second table.
Third, you should Create Page Process on Submit of type “PL/SQL anonymous block”, which will INSERT the calculated (entered) value into second table.
You gain:
1. Full power of ApEx to build automatically forms and reports.
2. Min. manual work.
3. You can use the select statement from the view to build your SQL query.
4. You are able to build and test that part of the application step by step.

How to create Insert & Update on master-detail form JPA/EJB 3.0

Is there any demonstration or tips how to Insert record on master-details form for JPA/EJB 3.0 with ADF binding?

I have master-detail forms (dept-emp). I drag the dept->operations->create method to JSF page. But when I click create button, only dept form is clear and ready for insert. But emp form is not clear. How can I add create method for this?
Can you give some example how to pass the right object to the persist or merge method so that it can save both the two objects (master-detail tables)
Thanks
