Java Project Architecture

can any body give me the project architecture in CMM Level companies?Does they are follwing any specific rules to frame this architecture?

The purpose of the Capability Maturity Model (CMM) is to measure the software development "process" of an organization.
The CMM is used as a guide to determine how mature an organization is in regards to their software process. It is based on process improvement.
It does not measure software development, it measures the "processes" within the organization. Examples of metrics include training, documentation, staff meetings, testing, quality assurance, project management, and contracting procedures.
It is typically used when contracting is involved, and for high-level software systems found in military, airline, automobile, and medical equipment industries.
CMM is dated. The current model is CMMI.
Organizations that produce software are measured using the CMMI model. The measurement is then certified by the SEI.
If an organization has a high CMMI rating, it can advertise it's rating and services and submit bids for contracts.
If an organization has a low CMMI rating, it can use the results of the measurement for improving its processes and identifying problem areas.
CMMI assessments are executed by certified individuals. If you are interested in having your staff certified, you must send them to the training courses at SEI.
If you are interested in having your organization measured with the CMMI, you must contact the SEI and submit a request.

Project Architecture

Hi..
I am now hunting for job in Java..
What does really a project architecture mean, while we are developing a project using JSP,Servlet and Struts . What a project flow diagram. Does both are almost same or different. What should be the answer of the question..(What is the architecture of your project ?) .
Plz help me out !

I guess the answer is something including the next explanations:
- Develop language (Jave, in this case)
- Kind of application (stand alone / web)
If web application:
- Web application server (Tomcat, Websphere, BEA Weblocig, etc.)
- Developing technology: Struts (framework implementing MVC pattern), JSP (View), ActionServlet (Controller), JavaBeans-EJB (Model), etc.
- Persistence: Hibernate (or other object persistence implementation) or DB access with SQL code embedded in Java code.

Project architecture in Oracle SOA Suite.

Hi,
Could any one please provide the info abt " How the Project Architecture is implemented and its steps in realtime in Oracle SOA suite 10g/11g ".
Thanks in advance,

Did you mean Project Structure ?
If yes, take a look at the following chapter in developer's guide.

Project architecture question

hello
iam trying to develop a mobile application using j2me to communicate with linux machine through wireless LAN .
my question is that iam confused about the project architecture.
ihave 2 ways:
1-develope desktop application working as aserver (on the linux machine) and the communication with mobile through streams.
OR
2-make the server is tomcat running my developed servlet and the communication through HTTP.
which way is prefered and why? or any other suggestions?
thanks in advanced.

HTTP is perfered because it is more widely supported.

Web project architecture question, mulitple .wars vs a single .war

I am in the early stage of architecting a web project.
At this point, I've came up with two solutions:
Multiple .wars
Each section would be it's own .war that would be built into an .ear. This would allow a multiple developers to work on the project and if a change would be made, then only the changed .war would need to be built.
However, then I would have mulitple copies of the same library for each .war, so that could slowly become a maintenance nightmare.
Also, I haven't figured out how to communicate between each .war - I don't believe I can cross container context?
Single .war
I wouldn't have to worry about multiple copies of the same library files. Nor would I have to worry about losing session data between applications since I would be running under one container.
But I am unsure of the best way to have more than one developer work on the project? It was suggested that I look at cruise-control at sourceforge.net - an automated build process - thus developers could check in their source code and a build would happen every xx minutes.
What is the best way to approach a project that is made up of multiple applications that need to be under one application suite?
Thanks,
--Todd

Hi,
I would recommend starting with the simple case which is using a single war file. You can use multiple wars, but it can add a bit of complexity and force you to learn a few advanced fetaures to get started. You can also share common libraries among multiple war files inside an ear file, and Java EE has mechanisms to allow that sharing (BluePrints has a document on adding libraries to Java apps at
https://bpcatalog.dev.java.net/nonav/enterprise/portableextensions/frames.html ) but it is does add a bit of complexity for you to learn initially.
A good rule of thumb is to start with one war file, and only split into other war files if really necessary. The most common style is one war file.

Multiple project architecture over one landscape.

Dear SolMan GURUS.
I ma facing the following issue. Aou customer want to create multiple project anvironment over one landscape (one ERP system). The project will be created accordint the the existing SAP modules (MM, SD, PP... etc.). But how can be the transports managed when for example several projects have their PRD transports planned on the same time. For example 12 PM. Will this work. I read, that you can use Cross System Object Locking. Or is there any other way. How we can solve this problem? Thank you for your reply.
Best regards,
Petr

We have used different way...

Determining the project architecture issue

Hi,
I have a architecture designing problem.
First version:
I had all the UI, Business manager and the persistence layer in the client side. So the UI came very heavy weight.
Second version:
I have the User Interface layer and Service Layer(will have the business and persistence layer)
We have the embedded database. Since the persistence layer is present in the service side, i am having the embedded database in the service side.
(it is more meaning full to have the database at the persistence side).
Case 1:
If i want to have the service as a common, for all the customers, then the embedded database will be common for all the customers.
Case 2:
If i give the service to each customers only, i will have unique db for each customers.
But to resolve this problem, if i want to have the database at the client side itself,
then it will not be good because, the persistence layer is only at the service side.
So i have to make the persistence layer at both client and the service side.
My aim is to make the UI as light weight.
I am so much confused.
May i kindly know, how to correct this problem.
Thanks in advance.
NANDAKUMAR.T

Hi PKR,
Thanks for the reply.
My Expectation: To reduce the client(exe) size, as small as posible.
My problem: "The Embedded DB is in the service side". So obviously the client(exe) file will be less in size. But for each customer i have to give the service as a separate copy. Then only they will have their data alone.
I want to achieve my expectation and to overcome, the facing problem.
Is there any way to do it and looking towards it.
Thanks in advance.

How to organize project structure for big application architecture

Hi all:
We prepare to construct a medium erp project using JHeadstart,
so we have some application system like human resource, accounting, inventory, ...
What's the best suite to organize application project architecture ?
we have this issue about application architecture:
1.how to fulfill large scale application and must to share some common view object and entity object in all application, May we to break the application down into multiple BC4J packae in same project or separate each subsystem in each project folder?

You can definitely organize your applications into as many packages as makes sense for your overall design.
You can create and deploye packages of BC4J components in simple *.jar archives and then uses features of JDeveloper to import those shared packaged of components in a read-only mode in projects that need to make use of them.

Complex query using 'sql like' statement.

Given the following basic class structure.
public class Project {
     private String name;
     private Architecture architecture;
     private Resources resources;
     public Architecture getArchitecture();
     public void setArchitecture(Architecture architecture);
     public Resources getResources();
     public void setResources();
     public String getName();
     public void setName(String name);
public Architecture {
     private String name;
     public String getName();
     public void setName(String name);
public Resources {
     private String name;
     public String getName();
     public void setName(String name);
we want to be able to do a query like:
     find all Projects where (Project.name.indexOf("a") > 0) &&
(Project.architecture.name.indexof("b") > 0)
In essence a "like" comparison across String properties of the JDO objects.
Is it supported in KODO?? Anyone tried it out? Also, is it possible to
generate SQL type query in KODO?

Note that this relies on a current bug in Kodo -- we should escape out the
'%' character, but we don't.
Some day, we'll fix that bug. But, before then, we will introduce a proper,
supported mechanism for finding records that have a string field that
contains some substring.

Hope it helps. oh, don't know about the generating sql query.

Question for jschell

Hi Jschell,
I have gone through a lot of posts on jdbc drivers and obviously a lot of them contain your replies. I have a question about JDBC-ODBC bridge and I think you are the right person to answer it with your experience.
My project architecture is as follows. I use Swing at the front end, MS Access 2002 as the database. This is a single user client server application. I am using JDBC-ODBC bridge as the jdbc driver. I have evaluated IDS server Type 3 Jdbc driver and found it no better Sun's Type 1 driver. Moreover this adds the overhead of running the IDS server as the service on the clients machine.
The database calls in the application are not in the high range. This application is not a prototype and it will be going to production soon. In this situation, please suggest me what JDBC driver I have to proceed with.
Thanks in advance
Bhaskar

Question for jschellIs that "jschell" thingy like an application? Or a library. Because I haven't heard of either. Maybe something for running a bikini shop on the beach (think about the "schell" part.) Now that would be interesting.
The database calls in the application are not in the high range. This
application is not a prototype and it will be going to production
soon. In this situation, please suggest me what JDBC driver I have to
proceed with.No idea. What does "high range" mean?
I had an application where we were supposed to handle something like 2000 transactions a second on an Oracle server. The Oracle guys just laughed and said that wasn't going to happen. We ended up re-writing the system and using a RAM drive to get close to what we needed. And that was all done in C++ and ProC. So exactly what you mean is important.
If you have a real person as the single user client and there is only one person, then I seriously doubt that you could overload ODBC. Even one of those fast typists that they used to put on TV back in the earlier 80s couldn't keep up with even a cheap windows box.
On the other hand if you are trying to replicate ebay or yahoo then you are dreaming if you try to use MS Access. It will get swamped in the first day if not the first hour. It doesn't matter what driver you use.
If it makes you feel better MS Access was used in a VB application to run the call center help desk 'info' database at the one placed I worked. And that was with 200 users. So it can certainly handle more than one user at a time. And it was also used for merchant (vs bank) tracking of credit card usage at casinos. And those places do quite a bit of volume - if you ever stood at line in Las Vegas for the all you can eat buffets at lunch/dinner then you know what I mean.

JSP 2.1 and JSF 1.2 support?

hi
when can we expect to see JSP 2.1 and JSF 1.2 support in JDeveloper?
br. aspa

Good question Neila!
Shay, thanks for the input.
We urgently need these informations in order to design our strategies for future projects architecturing. For exemple, we are working on new Java projects at my company and are relying on JDev + ADF Faces + EJB 3.0 + OAS 10.1.3, based on the current Oracle implementation. I'm affraid I will have to rewrite code after you release new versions of those. If yes, I'll be personally in a big trouble... :-)

Question about Encapsulation

I have two classes that have a parent-child relationship sort of.
interface IProject{
      void doIt();
class Project implements IProject{
     List architectures;
     public doIt(){
class Architecture {
     Project project;
}The question is how do I identify which project the architecture belongs to properly?
architecture is not a project but it does have a project and sometimes I need to know which project the architecture belongs to. So I return project not as a way to get the project from architecture, but as a way to identify which project the architecture belongs to. But it seems wrong to expose project from within architecture. But at the same time, project does not make up any of architectures behavior except if you call 'belonging' a behavior.
Maybe the answer is if you want to know which project the architecture belongs to you have to ask each project? This bidirectional relationship seems a bit odd. Maybe I can return from architecture a Project id or some kind of identifier but not the actual project?
In fact I dont think the architecture even needs to hold a reference to the project since its not using any behavior from the project. But I do need a sound way to indicate which project the architecture belongs to. preferrably from the architecture.

The question is how do I identify which project the
architecture belongs to properly?
By the way you phrased your question, you want to know what Project a given instance of Architecture belongs to. In this case, Architecture should have a reference to Project. I would do something like:
final public class Architecture {
final transient private Project parent;
public Architecture(final Project parent) {
         super();
         this.parent = parent;
// I am not providing an accessor method, so I have not yet 'exposed' the Project.
architecture is not a project but it does have a
project and sometimes I need to know which project
the architecture belongs to. So I return project not
as a way to get the project from architecture, but as
a way to identify which project the architecture
belongs to. But it seems wrong to expose project
from within architecture. But at the same time,
project does not make up any of architectures
behavior except if you call 'belonging' a behavior.
Belonging behavior indicates a dependency, which in Java is normally achieved by composition (see above).
Maybe the answer is if you want to know which project
the architecture belongs to you have to ask each
project? You lost me there. You went from Project to Architecture back to Project. What way are you navigating?
This bidirectional relationship seems a bit
odd. Maybe I can return from architecture a Project
id or some kind of identifier but not the actual
project?
That is fine. However, the id properly belongs within Project itself. IMO.
In fact I dont think the architecture even needs to
hold a reference to the project since its not using
any behavior from the project. This requirement contradicts:
But I do need a sound
way to indicate which project the architecture
belongs to. preferrably from the architecture.Which is it? Something A cannot both be A and not A at the same time.
