I need to call a remote website from my code and get the html data onto a string variable.

How do I do this using Java ?

I need help in writing queries in EJB 3.0. I am used to normal select statements in plain java. But I hear that in EJB 3.0, the syntax of writing a custom query is different.

Please help.

Hi.

I am trying to understand this code:

Hi there.

I am just beginning to learn some C++ programming. It is quite interesting and flexible. I think it is a good habit to understand algorithms through implementing them in code. I studied some ways to represent graph in the computer. It seems to me that adjacency matrix is most simplest.

I have heard that they take a lot of space. My question is, how do I use adjacency list to reduce this memory consumption? Do I have to allocate the array size dynamically during runtime? How do I do it?

Is there any simpler way to manage adjacency list?

Hi,

Thank you for reading my post. I am making a simple IDE for C++.  I have a compiler installed. I created a IDE like text editor where I can type my code and save it. Now I want a button which can compile the code on click and output the result. How do I do it? Is there anything as simple as system() in C++? I have googled for system() in java. But not much of a success.

Thanks again.

Hi.

I am a student of CSE. I am doing some project using open CV. I need to load a image and save each of the regions predefined in the program, as a separate image. How do i do it in C++?

For example, suppose I have a form with 8 fields, I shall give the pixels from where to crop and the lengths along with it.

The program should crop the image according to the location.

Hi,

In EJB, there a several bean types in the Session Bean Type category.

They are stateless and stateful. Which type should I choose for a new EJB project?

Hi,

I recently built a Robotic Arm to move objects by human Control. The model was fine and effective. So my new partner who is an Image Processing expert wants to work as a team to expand it.

The problem is, he is on Linux. I don’t know much of Linux. So is there any way I can interface the controller with a PC running Linux, using C++?

The current design uses a small keypad, having 12 keys to control the arm(8) to move (4) to up/down/hold/leave . Each of them generating a 8 bit signal. All I need is to generate the signal from a PC rather than a Controller pad.

I have two servers running Linux. A website is on one and the database with an EJB module on the other. I need to access the remote EJB methods from the web project. How do I get about it?
