Authentication - Best way to implement these requirements?

I'll be developing a J2EE application that will be deployed on OracleAS 10g. Oracle Internet Directory will contain usernames and passwords the be used for authentication, but application specific roles and privileges will be defined in the application database. Only a subset of users in OID will be allowed to access the application.
I'm new to J2EE security, and unsure how to implement this. Will I need to develop a customised LoginModule?
Please provide guidelines on how I should approach this.
Thanks in advance ...
Steve

All JPA strategies require something (like a table or sequence object) be in the database, with table sequencing being the most portable, though EclipseLink does allow custom sequence stratgies where you could use something else, such as the UUID. Sequencing is described here described here http://wiki.eclipse.org/EclipseLink/Examples/JPA/PrimaryKey with a custom UUID example shown here http://wiki.eclipse.org/EclipseLink/Examples/JPA/CustomSequencing .

Displaying Multiple Values on GUI components - best way to implement

Hi,
my program needs to implement a basic function that most commercial programs use very widely: If the program requires that a GUI component (say a JTextField) needs to display multiple values it either goes <blank> or say something more meaningfull like "multiple values". What is the best way of implementing it?
In particular:
My data is a class called "Student" that among other things has a field for the student name, like: protected String name; and the usual accessor methods (getName, setName) for it.
Assuming that the above data (i.e. Student objects) is stored in a ListModel and the user can select multiple "Students", if a JTextField is required to display the user selection (blank for multiple selections, or the student "name" for a single selection), what is the best (OO) way of implementing it? Is there any design pattern (best practice) for this basic piece of functionality? A crude way is to have the JTextField check and compare all the time the user selections one by one, but I'm sure there must be a more OO/better approach.
Any ideas much appreciated.
Kyri.

Ok, I will focus on building a solution on 12c.
right now I have used a USER_DATASTORE with a procedure to glue all the field together in one document.
This works fine for the search.
I have created a dummy table on which the index is created and also has an extra field which contains the key related to all the tables.
So, I have the following tables:
dummy_search
contracts
contract_ref
person_data
nac_data
and some other tables...
the current design is:
the index is on dummy_search.
When we update contracts table a trigger will update dummy_search.
same configuration for the other tables.
Now we see locking issues when having a lot of updates on these tables as the same time.
What is you advice for this situation?
Thanks,
Edward

What is the best way to implement default values stored in a DB table?

[JHeadstart 10.1.3 build 78]
[JDeveloper 10.1.3 SU4]
We are struggling on how to best implement default values that are stored in a DB table. What we have is a database table with (CODE_TYPE, TABLE_NAME, COLUMN_NAME, DEFAULT_VALUE) as columns. This way the application administrator can administer default values himself/herself. Now we need to find the best way to set these table supplied default values in new rows. Globally we are aware of two ways:
- override create() method on VO
- probably create a View Object on top of the database table with default values (we are capable of transposing the table and return exactly one row with a column for each default value) and use JHeadstarts item property 'Default Value'.
We prefer the latter, since this is more declarative, however we struggle with the EL expression needed to indicate the default value.
If we have a VO named "DefaultValues" with a SELECT on a view on top of our database table (transposed) returning exactly one row, let us say:
SELECT orglanguage, orgtype, orgstatus [...]
FROM v_default_values
--> returning exactly one row
and we want an EL expression on an item that needs the value from orglanguage. What will the EL expression be? Something like:
#{data.DefaultValuesPageDef.currentrow.orglanguage.inputValue}? We tried several things but they do not work. A static default value works, but every EL expression so far does not. We know that using "data" can be dangerous, but thought JHeadstart takes care of preparing the other Page Definitions, so it might be possible when you use JHeadstart.
Or is overriding the create() method the preferred way? Or do we have to look at a Managed Bean for our default values that we refer to from EL (let us say MyAppDefaultValuesBean) and in that case: how do you associate a Managed Bean with a VO?
Any help would be appreciated. Apart from these default values, things are going rather well in this first J2EE/JHS project for us!

Steven,
Thanks for the reply. Unfortunately whatever we try, we cannot get it to work. We started looking at the second option (since we do need default values also in table lay-out new rows). We created a DefaultValues ViewObject, added it to the Application Module, added an EL expressiona to the Default Display Value property (replacing your ending ")" with a "}" offcourse ;-)), ran the JAG so that a page definition was generated for DefaultValues and we managed to get it prepared when loading for example the Organisation's jspx page. However no default value appears in a new row (not in Form, not in Table layout).
I then created a quick application on top of the HR schema, added a DefaultValues ViewObject using one calculated attribute (set Salary fixed to 1000), added the EL expression to the Salary Default Display Value property in the Employees Group, made sure the DefaultValuesPageDef is prepared by adding it to the parameter section and I see it getting prepared. I also see a managed Bean is created in the Employees-bean.xml.
In the Embedded OC4J log we see:
16:01:01 DEBUG (JhsPageLifecycle) -executing onCreate
16:01:01 DEBUG (JhsPageLifecycle) -CreateEmployeesDefaultValues bean found, applying default values to new row
2006-08-02 16:01:01.825 WARNING [ADFc] Warning: No Method onCreateEmployees and no actionBinding CreateEmployees found.
Is it this warning we should be worried about? Since no default value is created.

We do not understand what is wrong and why the default values do not get created in the new rows (and it is taking us far too much time). Any chance the EL expression is still wrong? It is a shame that any syntax errors in EL expressions are not visible in some logfile. It looks like when EL expressions are wrong, they are ignored instead of raising an error...

Does Adobe Reader for iOS have the ability to open inbedded links to additional PDF docs? If not, then what would be the best way to use these already created PDF's?

Does Adobe Reader for iOS have the ability to open inbedded links created with Acrobat Standard to additional PDF docs? If not, then what would be the best way to use these already created PDF's on an I Pad?

driddy61,
As of June 2014, none of the Adobe Reader mobile products support the hyperlink action for opening a separate PDF document.
Adobe Reader for iOS
Adobe Reader for Android
Adobe Reader Touch for Windows 8
In addition, the Reader mobile products do not open multiple windows/documents simultaneously, which would make the navigation between PDF documents nearly impossible. (Once a hyperlink takes you to a different PDF document, you have no way to go back to the original PDF document.)
The only Adobe Reader product that fulfills your department's requirements is Adobe Reader XI (mostly for Windows/Mac desktop/laptop computers). Acrobat Pro and Standard are paid products.
Because you are in search of a less expensive device for your department, you could get a Windows tablet instead of a Windows desktop/laptop computer. Microsoft Surface Pro (that you've mentioned in your previous reply) is just one example. You can also find other less expensive Windows tablets.
Tablets
However, please keep in mind that there are two different types of Windows tablets running two different operating systems.
(a) A Windows tablet with an Intel-based processor running Windows 8.1 Pro
Example: Surface Pro 3
You can install and run traditional desktop apps (e.g. Adobe Reader XI) and new Windows Store apps ("Modern" or "Metro-style" apps).
(b) A Windows tablet with an ARM-based processor running Windows RT 8.1
Example: Surface 2
You can only install and run Windows Store apps (e.g. Adobe Reader Touch) but not traditional desktop apps like Adobe Reader XI.
In general, type (b) tablets are more affordable than type (a) tablets. However, if you want to run Adobe Reader XI, you do need to check the technical specification of each tablet and make sure the following conditions are met.
Processor: Intel
Operating system: Windows 8/8.1 or Windows 8/8.1 Pro, not RT
Hope this helps you choose the right device for your department. Please let us know if you have any questions about system requirements or supported features in the Adobe Reader products.

What is the best way to implement Carousel i.e. web part in a site page on office 365 site?

We can implement the Carousel web part in many ways like content By Query Web Part , jquery (nivo) plugin or content search web part etc. But among these which one is the best way to implement to get best performance of the page?
Thanks

content search web part always provides best performance because it uses the search. only consideration you need to take is, it does not display the changes immediately and you need to wait for the incremental crawl to happen.

Event Structures-best way to implement this UI?

I am trying to write a VI to control & read data from 4 different "channels" (each measuring a DUT) at once. I have written all the VI's for initializing instruments, communicating with the devices (VISA, GPIB), setting bias, reading data, etc...that has all completed. I just need to write the overall program with the user interface to allow the user to control these 4 channels & display the measured data.....as it turns out, this is the tricky part! My head is spinning from trying to figure out how to handle all the possible events.
Basically for each channel, I want the user to be able to
-enable/disable it for measurement (e.g. if there is no device loaded in Ch.3, we don't want to measure Ch.3..maybe disable/grey everything)
-set bias conditions (only if channel enabled). Allow user to change bias "in real-time" by increment/decrementing (e.g. incrementing from 5.00 V to 5.01 V, for example).
-turn biasing on/off (again, only if channel is enabled)
Also, I want each channel to display its measured data (e.g current, temperature reading)..every second or so. No graphs or anything fancy (for now! ), just numeric indicator.
Honestly, this all sounds so simple but I'm having trouble figuring out the best way to implement this, due to the fact that 1) there are multiple channels needing to be monitored for events 2) large number of user events that could occur (seems like at least 4 per channel - enabling/disabling, turning bias on/off, incrementing/decrementing bias values, etc ), Also the if a channel IS enabled, i want to be continously reading/displaying the data. What is the best way to handle this? Should i have 4 separate while loops, each with an event structure to handle events for that particular channel..or will that give me grief somewhre?
Also, I have another nagging question. Pretty much all the examples I see re: Event Structures and booleans involve latched booleans, eg. buttons that are just pressed once and pop back up...e.g. buttons you press to tell it to complete a task (e.g. "Acquire Data" or "Stop") , and once it's pressed it's over and reset. In my case, some of the booleans would not be latched...e.g. the "Enable Ch.2" button would be 'TRUE" as long as i want Ch. 2 to be read....does that make sense? Then, say hours later, if i did want to disable that channel, i would change it to "FALSE" and while that would be an "value change", the new value would not be "TRUE"..does that make sense? So not sure if that would be dealt with the same way in an Event Structure.
Hope this all makes sense and many thanks in advance for any help!!!

You're halfway there. I'd say the best solution is a producer/consumer structure, the event structure is used to generate queued commands to the consumer loop.
All data is handled in the consumer loop, where you among other things have an array of clusters of channel/instrument settings. (I usually have several cluster, one for test data, one for instrument settings, one for general settings and so on)
The event structure can have a 1 sec timeout, in which you queue up a Measure command.
In the consumer, in the measure state you loop through your instruments and if enabled you measure them and update their indicators.
The general (smart) way to setup the queue is with a cluster containing 2 elements, a typedef'd Command and a variant.
This way you can send data with the command in any form which is then interpreted in the consumer.
If, e.g. you press the Enable button on a channel, you can enqueue Enable and the channel number.

Display Server Name on the title of the WINDOW : Best Way to Implement

our weblogic is deployed in a clustered environment(group of weblogic instances)(say for eg) Server01,Server02,Server03). Every time the request will go to any one of the weblogic instances. Now i need to display the server name on the title of the IE window.
Web Application : - Server02(request 1)
Web Application : - Server03(request 2)
For that i've followed the following approach.
<filter>
<filter-name>AppFilter</filter-name>
<filter-class>com.src.app.AppFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>AppFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
All request will go thro' the filter.
In filter, dofilter method of AppFilter, set the server name as below.
request.setAttribute("HOSTNAME", (" " + InetAddress.getLocalHost().getHostName()));
In all jsp title,do the following.
<title>WEB Application <%= request.getAttribute("HOSTNAME") %></title>
This is working fine. I would like to know, if there's any better way of doing this?

Thanks for all your replies
user13118480,
We have one admin server and 3 managed servers.
3 managed servers are in different machines(sprd01,sprd02,sprd03).
we have a big ip configured against these managed servers. we expose only the big ip to the end user.
Based on load, the admin server will route the request to any one of the managed servers.
Reason for displaying the server name on window
The reason for displaying the Server Name (m/c name where managed server is running) on the window , is to help the developers to find out
the current logs.
log (app.log - logger file - log4j ) will go to sprd01,sprd02,sprd03.
now if we display the servername on the window, then we can direct go the machine and look for the logs.
otherwise,developer has to search for all in all the boxes.(sprd01,sprd02,sprd03)
Questions:
--Now i would like here more abt the Host HTTP header.
*1. is my approach to retreive the host machine name is good? is there any other simple way to get the host name?*
*2. as per your answer, are you asking me to get the host name from httpheader. request.getRemoteHost()?*
*3. is there any way i can set the title of the browser window from filter itself instead of setting requestAttribute in filter and reading the same in*
all the jsp's?
4. Is there any better way to implement this requirement?
baftos,
Reason for using a filter.
Tomorrow if i dont want to display the machine name in the window,
then all i need to do , is to change the filter statement as follows, instead of changing all the jsp's.
request.setAttribute("HOSTNAME", "");

Best way to implement m to n relation?

Could you please give me some advice on the best way to implement m-n relations in apex?
Example: I want to store server and database info. A server can have multiple database of course. But in case of a RAC database, the database can be running on multiple servers. So I have tables:
create table SERVERS (id number primary key, name varchar2(30));
create table DATABASES(id number primary key, name varchar2(30))
and an m-to-n table
create table SERV_DB(serv_id number references SERVERS(id), db_id number references DATABASES(id), instance_name varchar2(30))
So the table SERV_DB can tell me e.g. that database PROD is running on server 'prdsrv1' with instance PROD1 and on server 'prdsrv2' with instance name PROD2
How would you design an apex page to maintain this information (adding relations, updating instance names, etc)? I have a solution using checkboxes and 2 for-loops over htmldb_application.g_f40 (to process checkboxes) and g_f41 (to process text fields with instance names) and some delete statements but the logic behind it looks too complex for me. I am convinced that this can be done more simpler. Seems like a common problem to me, so I wonder if there is no out-of-the-box solution in apex for this?
Could you please show me or create a small demo application with the solution that looks most elegant to you?
Thanks,
Geert

Thanks for your reply. You modified the question slightly, but conceptually it is still the same. What you call the instances table corresponds with my serv_db table. I understand the solution you propose using the tabular report. If I see it correctly, you would have an insert button above the tabular report for each new relation (instance - server) you would want to add. This is ok for the case i used (databases, servers, instances) because there are relatively few relations. However I would not like this solution for other cases. E.g.:
case: you have a list of persons and a list of tasks. You want to assign tasks to persons in a way that each person has multiple tasks to do and each task can be assigned to multiple persons.
Suppose you add a new person, and you want to assign 15 tasks to him. The solution above (with the tabular report) would be quite some work because you would have to click 15 times on the insert button and on each click select a task from the select list. In this case it would be more appropriate to, after selecting the new person, see a list of all tasks (e.g. 30 tasks) with a checkbox in front, so you can mark 15 out of the 30 checkboxes and press submit. It gets more complex when you want to assign also an attribute to the relation, i.e. showing the list with all tasks, a checkbox in front and a select list next to each task where you can choose from e.g. "priority high" or "priority low" to indicate that this task is high or low priority for that person. Is there an easy way to implement that?

Best way to implement app wide process

I am working on an application that has a list of art work in an sql report.. I want to be able to add each piece to a collection of items (which is stored in a table), so I added another column to the sql report to store the id of the art work. I am just wondering what is the best way to implement the process to insert the item to the collection of items. Since I want to do this from multiple pages - link from art work sql report; link from the edit page for a particular art work; and on the artists page where there is also an sql report, I thought it may be best to have an application process, to save duplicating the process on multiple pages.. however I don't think there's a way to pass the id of the item to the application process? as I was thinking best to have the application process conditional based on request, and then have the link as a doSubmit().
So is it best just to have the link redirect to the same page, passing the id of the item, and then having a process that runs before header that inserts the item, then assigning the item to NULL?
Thanks in advance,
Trent

Hi
What is the best way to implement this code in labview programming.
I have an analogue input which triggers a boolean light when it reaches a certain voltage. but at the same time i would like it to enable two other outputs one for a set period of time and the other stay on until another statement becomes true.
For example

Set output low
Case 2:
Set output high
If statement 2 is true
then set out put low
if not then repeat until statement is true
Thanks for your help

Hi David,
The code you posted will work, although note that the front panel becomes 'unresponsive' - as changes in the controls are only read once per iteration. The wait function is an example of an execution timing VI, however if we want to do software timing (like a 2 hour wait) - we should use software timing VIs.
Check out the following example (note we can stop execution during run-time):

I have purchases that are free for logged in users. What's the best way to implement a no-payment solution? Would having the payment fields hidden and COD auto-selected if the amount field is 0.00 a good idea? Is there a better way anyone has implemented this? And how about security flaws?

Hi
Here is an article about "no cost" orders
COD payment method will not work for zero value orders , you will need to use the Free payment method described
in this article http://kb.worldsecuresystems.com/893/bc_893.html
Hope this helps!

Best way to implement service in 3-tier webarchitecture

Hi,
What would be the best way to implement a service in the following 3-tier TopLink architecture: no ejb and a webclient (jsp/servlets)?
Currently I have a server session type and a service pojo using a singleton SessionFactory. The service pojo is used by the jsp/servlets.
Should the service pojo be a singleton? Should a SessionManager be used?
In the examples on OTN a clientsession is directly acquired in the jsp/servlets.
Thanks,
Ronald

Ronald,
There are numerous ways to do this. I would recommend using the SessionFactory. The SessionFactory makes use of the SessionManager, which holds onto the singleton Server session. You can then acquire client sessions using the oracle.toplink.sessions.Session interface from the SessionFactory. There is no need to hold the SessionFactory in a singleton yourself and you do not need to reference the ClientSession directly either.
We have introduced this latest approach to simplify coding. It will work in both the web architecture with JSP/Servlets accessing the sessions as well as within an EJB tier (Session/Message Driven beans).
