How to design a Java-basedNetworkLayoutTool for specifying networktopology?

hi,
i had given a project which is a webbased project where the user can design their whole network topolgy.
the technolgy is ultimately java only because it is web based.
technologies are java,swing,xml.
The GUI or front end should be designed in such a way that clients or end users can specify their whole network technology and can simulate it.
The GUI components are:-
1)Menu
2)Dockable or Movable tool bar
3)Tool bar should contain elements or components like(WAN,NODE,VR(virtua router),Frame Relay,UNI Directional,Bi Directional Links)
4)A drawable area where the user can draw whole network using elements of the toolbar.
5)designing property pages for all the elements like(for node(ipaddress,port),for Wan(some properties))
i have to do this in just a few days.iam not getting any idea how to approach?so please any body give me a suggestion of how to approach?
please also suggest me if i get any source code or samples or atleast articles on all related topics??
please help me..
regards
varma

Hehehe, it is nice with school assignments.
Well, it is not easily solvable as a webproject since the interaction demanded is higher than could easily be provided by a webbrowser.
Recomendations:
Assess the requirements on your system. What you probably will find that to achive that sort of interaction, you will have to switch to one of the following technologies: DHTM+javascript, Flash or deratives or java applet/webstart. All have advantages and drawbacks. Since you are posting here, I presume you are planning to go for the applet/webstart approach.
For the application:
1) Go through the swing tutorial to familiarise yourself to the swing components.
2) Read extra on LayoutManagers as you probably will be doing one of them if you want extra points. Otherwise a null-layout is usuable as well for your assignment.
3) For your different sorts of nodes and their definitions, for extra points, read about visual-proxies on javaworld ( http://www.javaworld.com/javaworld/jw-07-1999/jw-07-toolbox.html ).
4) Run to the store and buy anything that contains caffiene, guaruana or any other revitilasing content.
5) Design the application in a nice CASE tool. Don't do any of the normally important sequence diagram because of the time constraints.
6) Define a nice XML interface to be used by your application, based upon the requirements.
7) Draw your initial UI design on paper. And, yes, I do mean paper. If you can't draw it roughly, you will never be able to implement it. Also, since drawing is a pain, the UI usually seem to end up being simplier and more understandably by the users.
8) Code! I would start with the GUI and applet. The communication back to the webserver should be straigth enough and will not take so much time.
9) Test! Why did you think you where finished already, you must have missed something.
10) Deliver product, reap rewards.

How do i clear java caches for Mac OS X, version 10.6.8?

how do i clear java caches for Mac OS X, version 10.6.8?

Sarah2565 wrote:

Yes. Always keep the default settings unless you have a specific reason not to.
If you are a heavy user of Java programs or applets, you may need to clear the cache files after Java updates because the old caches may interfere.

How to design channel select VI for Agilent34970A

Hello Guys,
I want to design a temperature data acquisition system by using 34970A,but now i have a problem that i don't know how to design a channels selecting vi?
My idea is to select any channel from multiple channels to scan,pls help me for explaining how to do,because my labviw knowledge and experience is so poor.

Thanks for the response. In order to incorporate the sampling information (sampling frequency) into my data ( 160 X 512 2-D Array), I use "Build Waveform.vi." However, for the input argument "Y," I can only use a 1-D array. I try with my 2-D array, but it gives me a connection error. So, my first thought was to stick the Build Waveform.vi into a for loop with a shift register. I use an indexing tunnel node when guiding my data array into the loop. I then connect the 1-D array to the build waveform.vi, and send the output to a "Build Array.vi" where the output goes to the shift register, and the other input comes from the first shift register. What prevents this from working i.e., creating a 2-D waveform array, is that the option to uncheck the "Concatenate Inputs" is not available when i right click on the Build Array.vi. I notice that I do have the option to uncheck it when i'm just using 2 waveforms without the shift register. Would you have any suggestions? I want keep it running as efficient as possible, so i figured that I might want to avoid doing the filtering 160*13 times, manually.
would there be any advantage to using the Digital IIR Filter.vi over the Butterworth Filter.vi ? The input for the former is a waveform while for the latter is a plain ol' array, but i notice that i can send a waveform into it and i don't get an error.

Okay, first suggestion is to never create database connections in JSP/Servlet. SInce you mentioned MVC, JSP is the View, and a servlet can be the controller to process requests and redirect accordingly.
This piece of code should be in a class invoked from the model layer (business logic components) preferably with some abstraction. Maybe you should search around for DAO pattern. That might give you an idea.

How to Enable Custom Java Scripts for forms in Planning 11.1.2.2

I am working on Planning 11.1.2.2 right now.
Planning admin guide says, there is no explicit requirement to enable java Script for planning forms.
I set simple alert to see text "Hello World" in function validateForm() function in custom/validateData.js file - to see and test that alert when I save data for my selected application/form.
Closed javascript file and workspace, and planning application web page. Since I have not to do anything new to enable this java script alert, I opened that form and saved data to see if I can see my alert.. I got no alert, except "data are saved".
Has anything changed since last version? Am I missing something? Or, do I need to recycle services to get this alert?
thanks in advance.

Thanks guys, for your quick replies..!
Not sure what I missed, but I still have a hard time finding my "Hello World" alert.
What I did, is here.
a. Cleared all cookies and temp files from IE.
b. Updated validateData.js file from ear / war files using 7-zip program at given path from your link.
c. Stopped EPM services
d. Dropped tmp folder.
e. Started EPM services and let system deploy ear file (with my java script code).
All services are up. I can see EAR file deployed and java script file ValidateData.js has all my changes in new tmp folder now.
I am able to open my application and form.
But, my "Hello World" alert is still not appearing. Form is saved and saw message as usual.
One exception I noticed in my path. I have ....user_projects\domains\EPMSystem\servers\EPMServer0\.... in place of ....user_projects\domains\EPMSystem\servers\Planning_0\.... in my path. Planning_0 is replaced by EPMServer0 in this version. Rest is all same.
Any clue? thanks in advance,

How to design insertion and report for customers

I develop a web application in which I provide a web interface for inserting a customer. I model this customer as a class and provide its attributes. I have functions like addCustomer that inserts a customer's details in DB and getDetails() that returns a customer's attributes as an array. I have designed this for dealing with a single customer.
Now I want to list all customers from DB. I think another class should be created with a listing function that has multiple references(multiplicity) for the customer class. It is a easy task to retrieve all customer using a query and display it. But I don't know how to model this. I don't want to create one object for all available customers and display the details of each customer. Then How to model this and how to implement this using classes.
Can U tell me a resource or article that handles similar task.
Thanks.

Hi,
Create a POJO called customer ( plain java object which represent the persistant data ) and a Customer manager which is reponsible for retrieving a list of customer.
So the Customer manager will deal with retrieving the customer list.

How to design a wcf service for specific requirement

i have 2 question on wcf.
1) suppose some one develop a bus booking service using wcf and expose the same service over 2 different endpoint like tcp and http but i like to know what would be the advantage of having 2 or more endpoint for single service ? in what kind of situation
people use this trick? discuss in details.
2) how can i offer some extra functionality for tcp client. suppose my service has 5 function but http client can call only 2 and tcp client can call all. how do i design wcf service in this way. any idea would be appreciated. thanks

Hi Mou_kolkata,
>> 1)what would be the advantage of having 2 or more endpoint for single service ? in what kind of situation people use this trick? discuss in details.
In my mind the advantage of providing different endpoints for a single service is that each endpoint could use different binding and we would use different endpoints for logical grouping by function, we could also apply different levels of security
in the binding for each endpoint. For example you can expose an interoperable endpoint for Java, PHP, ... clients and a proprietary binary endpoint which could be faster but only for .NET clients.
Besides, please also try to check this similar thread:
http://stackoverflow.com/questions/6033788/when-why-would-i-use-multiple-endpoints-vs-a-single-endpoint-in-a-wcf-service .
>> 2) how can i offer some extra functionality for tcp client. suppose my service has 5 function but http client can call only 2 and tcp client can call all. how do i design wcf service in this way. any idea would be appreciated.
An esay way is to create two services. One service is for http client with 2 functions and the other service is for tcp client with 5 functions.
Or maybe you need do some authentication, for more information, please try to refer to:
http://stackoverflow.com/questions/11566182/how-do-i-restrict-access-to-some-methods-in-wcf .

To give a brief of how to develop UI using JS you can use ScriptUI to develop your UI, it is a fast and OS independent approach to UI development. The UI created using JS is native in look. You can refer the following link for some help on ScriptUI
http://www.kahrel.plus.com/indesign/scriptui.html
I don't have much info regarding development in CS SDK, but i can point you to one more direction of dev called as hybrid plugins wherein the UI is created in CS SDK, and appropriate methods are exposed from the C++ plugin(enhancing the script object model) to be called up by the CS code for too and fro communication between these two modules of code.

[Solved] How to use Oracle Java 6 for specific applications

I use an IDE called PyCharm. On its download page, it recommends using Java 6 instead of OpenJDK. I currently have jdk7-openjdk installed, and from what I had read in the Arch Wiki on Java, it should be possible to install Oracle Java 6 along side OpenJDK 7.
However, after installing jdk6-compat and jre6-compat, I still see that I am running OpenJDK 7 when I run the following:
% java -version
java version "1.7.0_09"
OpenJDK Runtime Environment (IcedTea7 2.3.3) (ArchLinux build 7.u9_2.3.3-1-x86_64)
OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)
...even after I have set JAVA_HOME and added /opt/java6/bin to my path.
How can I get PyCharm (or other applications) to use Oracle Java 6 instead of OpenJDK?
Thanks, and apologies if I've posted in the wrong place.
Other information that might be helpful:
Running zsh as default shell
Using Gnome 3 as DE
Last edited by Nikorasu (2012-11-17 20:54:33)

I found the solution.
For Pycharm, I just needed to add an environment variable PYCHARM_JDK. For running specific applications, I asked this question on the Unix / Linux StackExchange and got an answer there.
Also, after running PyCharm in Java 6... I would not recommend it. OpenJDK works fine
