Beyond JDeveloper 9.0.3 modeling features

Hi, I'm really impressed by the way JDev 9.0.3 enhance productivity while modeling EJB on Class Diagrams and other modeling features alredy present.
Having read the book "Developing Enterprise Java Applications with J2EE and UML" (ISBN: 0201738295) I was wondering if I can see JDeveloper takes the next level on the modeling side to become a complete J2EE Software Development tool.
My wish list follows:
-Use case Diagrams
-Sequence/Collaboration Diagrams
-Component Diagrams
-Deployment Diagrams
-Complete UML support for J2EE (profiles for J2EE)
-Patterns library
Is that direction JDeveloper will follow or it will remain just as a traditional ide?
Is there any timeline for such integration (approx dates)?
I've just tried Rational XDE but the high price tag is a barrier.
Thanks

What version of cvs client are you using? From the warning message it looks like JDeveloper is not compatible with the cvs client you are using, as it cvs is ignoring of the parameters JDeveloper is passing to the cvs client.

That is installed, successfully and Eclipse restarts.
Repeat Step 2 above.
Same Error.

David,
From what you write, it looks like it depends on a quite old version of
Ecore Tools (and so it's not a very active project producing update site
based on recent versions of other projects). It looks like you can fine
the old version of Ecore tools from this page:
https://www.eclipse.org/ecoretools/download.html
You'd need to add that to your "Available update sites" preferences.

Cisco ASA models features

Hi,
I am little confused with different models of Cisco ASA Firewalls. I am trying to understand the real benefit of ASA Next-GEN ASA Firewalls. I understand the next-gen has visibility up to layer 7 but:
- with CX the previous gen of ASA Firewall had same or similar capability?
- Is CX removed from Next-Gen FW?
- Is AVC something apart from CX and new featue in the Next-Gen FW?
- What is the real advantage of upgrading to next-gen FW from older gen ASA Firewalls?
Thanks

Next Generation Firewall (NGFW) is partly a marketing term. Wikipedia has a definition (as does Gartner and a host of others). Typically it's understood to mean something more than a simple stateful firewall that only looks at packets up to the TCP session level.
Cisco ASA has had add-on features for years like IPS modules and the ability to use Identities in access-lists that could arguably called NGFW. More recently they had the CX module (now Approaching End of Sales). It had several NGFW features including AVC, Web Security Essentials (WSE) and IPS.
The current product lineup include the FirePOWER modules with technology acquired from Sourcefire being developed and integrated into the Cisco security portfolio, including ASAs. Those also have AVC (basically the ability to look deep into a flow and determine application-specific (or even "microapplication") information. You leverage that with the addition of IPS, Web filtering and/or Advanced Malware Protection (AMP) licenses on the FirePOWER modules.
The advantage is that you are able to protect your enterprise from modern-day threats. With the vast majority of malware being exploits from web pages (or at least carried over http/https), the traditional firewall with a rule allowing, say, only http from inside clients does nothing to protect against those threats. Client side anti-malware software can help, but it may be too late once the malware has been identified.

Jdeveloper 11g team development model when develpoing ADF JSF application.

We have a application include five nearly 10 screens developed using J dev 11g.
Our application conteins model and view projects.
We want some of our developer develop some of the screen of project and other programmer develop the other screens. Just one developer responsible from Model projects.
We shared responsibility between programmers such as.
Programmer1 --> input.jspx
Programmer2 --> edit.jspx
We gave programmer projects files. They develop the new screens.
But When we want to combine the screen, some of the shared files suchas (databinding.cpx) couses problems.
How can we manage this kinds of situations. We don't want to create a new projects for each screen.
We are using cvs. But shared files couses problems in CVS also.
is there any metodology you recommend ?
Thanks.

Hi,
Many of our users work in this same way - one application, one model project and one view/controller project. As you are using CVS I would suggest the following:
1. Have each developer check out the whole application, not just the project
This is because
a. there are dependencies between the model and VC project
b. many of the files also have dependencies (Java/XML metadata, binding, pagedef....)
2. Make use of Pending Changes
a. use outgoing changes to ensure that you check in all changed files
b. be careful that all your outgoing changes are properly checked in - as CVS does not do atomic commits you can experience the situation where some file dependencies are not check in (for example if a network failure). SVN does do atomic commits, by the way
c. use incoming changes to see changes that have been checked in by other developers - this allows you to do a Compare of files such as DataBindings.cpx to see what changes have been made and, if necessary, to discuss with the other developer prior to doing an update
3. Use JDevelopers Merge Conflict resolution functionality to merge any conflicts in files
4. If you are using Task Flows consider having one developer who is responsible for adding/editing them
a. The information that is shown on the design view is taken from the source XML file - so these will need to be merged if multiple users check in
b. There is a diagram file associated with each task flow (eg adf-config.adfc_diagram) - this holds the x.y postional information of each shape on the diagram. If a diagram is edited by multiple users it can be complicated to decide which positional info should take precedence
Can you give me an example of the problems you are experiencing with the data binding file?

JDeveloper 11 - Feature Request

Sorry, I posted this in the wrong forum earlier - please see below - I would appreciate any further information that you may have on this matter - thanks in advance for your help
Will JDeveloper 11 have any additional features/functionality to aid the development of Swing based applications using a drag and drop GUI?
In particular I am interested to know if JDeveloper 11 will have the new/additional swing layout managers available, such as Group Layout, which is now part of Java 6.
The latest version of netbeans allows you to utilise the Group Layout in this manner, which speeds up the development of complicated Swing Frames and Panels. I have managed to find an online demo of this for your reference:
http://www.netbeans.org/files/documents/4/475/matisse.html
I look forward to hearing any further information and your views on this....
Thanks
David
Response from Shay below
Please post JDeveloper 11 related question on the JDeveloper 11 forum.
JDeveloper and OC4J 11g Technology Preview
Specifically for the group layout we are looking into this but it probably won't make it into the first 11 release.
We do have support for the JGoodies layout though today
See this demo:
http://www.oracle.com/technology/products/jdev/tips/muench/screencasts/simplejgoodies/binding_demo.html?_template=/ocom/ocom_item_templates/print
One thing to be careful with Netbeans and Matisse is that it locks your code so you can't code changes to the UI. If you do want to change something it will break your visual editing.
Response from me below
Thanks for this info Shay, I will repost my query in the JDeveloper 11 forum.
Not being a regular user of Netbeans I did not know that it locks your code, one of my colleagues was showing me how easy it was to develop Swing GUI's using group layout within Netbeans earlier and I thought that it would be a nice addition for JDeveloper to have. I will make sure my colleagues are aware of this limitation when I am back in the office tomorrow.
Thanks for the update.
David

David Ferguson,
Such features are currently under consideration for future releases of JDeveloper 11. Thank you for your effort and help. It is this kind of insight that will make JDeveloper the best product possible.

Just got back from odtug, where's the data modeling?

I could just have not been paying attention, but I thought in one of Sue Harper's presentations she demonstrated the data modeling feature that I've seen a little mentioned about on here. Was that just a sneak peak of what to come or am I just looking over it in 1.5.1?

Yep - Sue was giving us a sneak peek at a new feature now under development. She said (with the usual caveats about dates) that she hoped to have something more to show, and maybe to try by the time of Oracle Open World. The modeling feature is not in the current version.
If you need modeling right now, I suggest that you install JDeveloper. Its modeling tools are pretty good, though it stores metadata in XML files, not in a database. A database for metadata is the major advantage that the coming modeling tool for SQL Developer will have.

JDeveloper capabilities for Reverse Engineering existing instances and data

We are experiencing difficulty obtaining the indexes, synonyms, and triggers via reverse-engineering capture of existing 10g DB's. Does JDeveloper have the capabilities for Reverse Engineering all objects from existing DB's ?
Will 10g JDeveloper handle reverse-engineering large 300 table schemas rich with large quantity of indexes, synonyms, & triggers?
And last, how can a listing of the Data Dictionary be extracted /exported in CSV or excel format for review distribution? Via JDeveloper? We have a large distributed development, test, quality, and integration team which prefers to review various elements of schema updates and changes in excel.
Thanx.

Vicki-
Thanks for the additional info. I was thinking you were most concerned with reverse-engineering existing schemas. I did not realize you were designing new schemas.
When you mention ERDs, are you interested in logical ERDs (as compared to physical tables and foreign keys)? If you are interested in doing pure logical ERD modelling, then Designer is the way to go. It has been years since I worked with Designer, but it has ooodles of capabilities to forward and reverse engineer between databases, physical models, and logical models of schemas. It sounds like you might be using Designer today and are hitting some snags. Is this the case? If so, I suggest you see if Oracle Support or the Designer forum can help you get past the specific Designer issues. The forum for Oracle Designer is here: Designer
Sue mention that JDeveloper does support database modelling. Here is a how-to for JDeveloper 11g that shows how it works:
http://www.oracle.com/technology/obe/obe11jdev/11/db_dev/obe_%20databasedevmt.htm
The how-to is pretty complete showing you forward and reverse engineering capabilities.
A few more minor notes:
1.The JDeveloper schema modelling features work on a physical (not logical) level. In other words, they work on tables not entities.
2.The SQL Developer report features certainly work on "DATA". But, the "DATA" they work on can certainly be the data dictionary data. In other words, I can write a report in SQL Developer that queries all of the column names, column data types for a subset of tables. Then I can export that "DATA" into excel and use it for whatever your downstream needs are. The potential capabilities are practically unlimited.
Cheers,

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.
1.2 MVC framework
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?

Problems with database modelling and primary keys

Hi,
I use JDeveloper exclusively for data modelling and generating the sql to build my db.
Its good but i have found a bug that can be rather annoying:
If i change the primary key of a table, the change does not seem to register within the model. So when i try and create a foreign key relationship to another table, the type is of the old type (say i went from varchar2 to number).
The only way around this is to delete the table and create it again. This also causes problems because the db generation wizard will then refuse to open properly (because it does not know that a table has been deleted).
Is this a known issue?
Cheers
Rakesh

Is this forum meant for reporting bugs or not? This issue i have stated is repeatable and in the current version.

Hello, I've downloaded both jDeveloper 10g 10.1.3(J2EE) and
10.1.2, I'm developing for an OAS 9.0.4 and I want to know which version of OC4J they come with.
I want to develop with exactly the same version of the production server.
Maybe I must use the jDeveloper 9.0.5.2 version..
Could anyone give more information about that?
Thanks!

I have verified that the version number of jDeveloper matches with the oc4j that it comes with it.
But i've also realized that the newer versions of jDeveloper comes with new interesting features. So my question now is can I change the OC4J embebed into jDeveloper? That way I could use the jDeveloper J2EE edition with a 9.0.4

Jdeveloper cannot load Use Case Diagram

Hi all,
I have a set of use-case diagrams that I worked on and everything has been coming fine until now. Suddenly, the diagrams cannot load, and I get this error message anytime I try to start jDeveloper:
java.lang.IllegalStateException: Models cannot be loaded until registration is completed

Any help please ?

Hi,
This turns out to have been an interaction between the AspectJ addin and the UML modelers. If you turn of the AspectJ addin the problem goes away. The issue has been logged against the AspectJ addin as:
https://jdeveloperaop.dev.java.net/issues/show_bug.cgi?id=1
There should be a fix avaliable soon,
Gerard
