The Essence of EJMs
EJMs (Enterprise JavaBeans Modules) are a key component of Java EE (Enterprise Edition), providing a standardized way to develop and deploy enterprise applications. They offer several advantages that have made them popular among Java developers:
- Improved Reusability: EJMs can be easily reused across multiple applications, reducing development and maintenance costs.
- Statelessness: EJMs are inherently stateless, ensuring that different clients can access the same EJM instance without interfering with each other.
- Declarative Configuration: EJMs use a declarative approach to configuration, allowing developers to define business logic and application behavior in XML files.
- Transaction Management: EJMs provide built-in transaction management capabilities, ensuring data integrity and consistency across multiple EJB interactions.
EJMs are classified into two main types:
| Type of EJM | Features |
|---|---|
| Session Bean | Maintains state during a single user session and is typically used for UI interactions. |
| Entity Bean | Represents persistent data in the database and is used for managing business objects. |
Adding Details for Substance
### Basic Shading
Begin by establishing the basic shadow areas. Use a soft pencil to lightly shade areas where the light source is blocked. Gradually increase the pressure to create darker shadows. Pay attention to where the shadows fall naturally, considering the shape and angle of the object.
### Varying Line Weight
Alter the thickness of the lines to emphasize certain features. Thicker lines can create a sense of depth or highlight important contours. Use thinner lines for more subtle details or distant objects. Experiment with different line weights to achieve a balance between visual interest and clarity.
### Adding Texture
Incorporate textures to add interest and realism. Use short, parallel lines to represent fabrics, or small dots to create a stippled effect. Cross-hatching or blending different shades can create the illusion of depth and surface variation. Experiment with various techniques to achieve the desired texture.
| Texture | Technique | Example |
|---|---|---|
| Fabric | Short, parallel lines | Clothing, curtains |
| Stipple | Small dots | Skin, grass |
| Cross-hatching | Intersecting lines | Wood, metal |
| Blending | Combining different shades | Clouds, smoke |
Facial Expressions: Conveying Emotion
1. Smiling
A smile is a universal expression of happiness and contentment. It involves the upward turn of the mouth corners and the crinkling of the eyes. A genuine smile also engages the muscles around the eyes, creating “crow’s feet” lines.
2. Frowning
A frown is the opposite of a smile and conveys sadness, disappointment, or disapproval. It involves the downward turn of the mouth corners and the creasing of the forehead.
3. Anger
Anger is expressed through a clenched jaw, narrowed eyes, and a flared nose. The eyebrows are often drawn together, and the mouth may be set in a snarl or a grimace.
4. Surprise
Surprise is indicated by a wide-open mouth, raised eyebrows, and bulging eyes. The hands may be raised to the face, covering the mouth or eyes in astonishment.
5. Complex Emotions
Many emotions are not easily categorized as positive or negative. These more complex emotions often require a combination of facial expressions to accurately convey the feeling.
| Emotion | Facial Expression |
|---|---|
| Sadness mixed with Anger | Downward turn of the mouth, narrowed eyes, furrowed brow |
| Happiness mixed with Surprise | Upward turn of the mouth, raised eyebrows, slightly widened eyes |
| Fear mixed with Anger | Wide-open eyes, raised eyebrows, flared nostrils, clenched jaw |
Color Theory: Bringing EJMs to Life
Fundamentals of Color Theory
Color theory is the study of how colors interact and affect each other. It helps artists understand how to create harmonious and visually appealing compositions. Understanding the basics of color theory is essential for creating believable and realistic EJMs.
Color Wheel
The color wheel is a circular representation of the colors of the spectrum. It is divided into three primary colors (red, yellow, and blue), three secondary colors (green, orange, and purple), and six tertiary colors (e.g., red-violet, yellow-green). The color wheel helps artists identify complementary colors, which are colors that are opposite each other on the wheel and create high contrast when used together.
Color Harmony
Color harmony refers to the pleasing arrangement of colors in an image. There are several different color harmonies, including monochromatic (shades of the same color), complementary (colors opposite each other on the wheel), and analogous (colors adjacent to each other on the wheel).
Analogous Harmony
Analogous harmony is created by using three or more colors that are adjacent to each other on the color wheel. This type of harmony creates a sense of unity and flow in an image. For example, a sunset can be depicted using analogous colors such as orange, yellow, and red.
Triadic Harmony
Triadic harmony is created by using three colors that are equally spaced around the color wheel. This type of harmony creates a vibrant and eye-catching effect. For example, a landscape can be depicted using triadic colors such as blue, yellow, and red.
Complementary Harmony
Complementary harmony is created by using two colors that are opposite each other on the color wheel. This type of harmony creates high contrast and visual impact. For example, a city skyline can be depicted using complementary colors such as blue and orange.
Tints and Shades
Tints are created by adding white to a color, while shades are created by adding black to a color. Tints and shades can be used to create subtle variations in color and to create depth and dimension in an image.
| Tone | Definition |
|---|---|
| Tint | Color mixed with white |
| Shade | Color mixed with black |
Background Elements: Setting the Scene
8. Color Gradations and Shadows
Color gradations and shadows add depth and realism to your scene. To create a gradual transition between colors, simply blend the adjacent colors using a blending tool or brush. Use darker shades to create shadows, which can help to define the shapes and forms of your objects.
Tips for creating effective color gradations and shadows:
- Use a soft blending brush to create smooth transitions between colors.
- Start with a light base color and gradually add darker shades to create shadows.
- Consider the direction of the light source when creating shadows.
- Use multiple layers to build up the color and shadows, allowing you to make adjustments as needed.
The following table provides some common color combinations and their corresponding shadow shades:
| Color | Shadow Shade |
|---|---|
| Light Blue | Dark Blue |
| Green | Dark Green |
| Orange | Brown |
| Red | Dark Red |
| Yellow | Brown |
Composition: Crafting a Powerful Image
Elements of Composition
When composing an EJM, consider the following elements:
- Line: The path taken by a point as it moves.
- Shape: A two-dimensional area defined by lines or curves.
- Texture: The surface quality of an object.
- Value: The lightness or darkness of a color.
- Color: A hue with a specific saturation and value.
- Space: The area around or within an object.
- Form: The three-dimensional aspect of an object.
Principles of Composition
To create a compelling EJM, adhere to the following principles:
- Unity: Connecting all elements so that they form a cohesive whole.
- Balance: Distributing elements evenly or placing them in an asymmetrical manner that creates visual stability.
- Contrast: Using differences in value, color, or texture to create visual interest.
- Proportion: Determining the relative sizes of different elements to establish visual harmony.
- Rhythm: Creating a sense of movement through the repetition or variation of elements.
- Emphasis: Drawing attention to specific elements or areas using contrast, color, or other techniques.
- Perspective: Creating the illusion of depth and distance using techniques such as linear perspective or vanishing points.
Common Composition Techniques
Employ the following techniques to enhance your EJM compositions:
- Rule of Thirds: Dividing the canvas into thirds horizontally and vertically and placing key elements along the lines or at the intersections.
- Golden Ratio: Using the mathematical ratio of approximately 1.618 to determine the proportions of elements within the composition.
- Leading Lines: Using lines within the composition to guide the viewer’s eye toward a focal point.
- Negative Space: Utilizing the areas around or within objects to create visual interest and balance.
- Cropping: Positioning elements within the frame to eliminate distractions and focus on the most important aspects.
How to Draw EJMs
EJMs (Enterprise JavaBeans) are a Java-based technology that simplifies the development of enterprise applications. They provide a way to package and deploy business logic in a reusable and scalable manner. Drawing EJMs can be a useful way to visualize the structure and interactions of an enterprise application.
To draw an EJM, you should first create a diagram that represents the overall architecture of your application. This diagram should include the different components of your application, such as the EJBs, the database, and the user interface. Once you have created this diagram, you can start to draw the individual EJMs.
When drawing an EJM, you should use the following symbols:
* A rectangle to represent the EJB
* A circle to represent the EJB’s home interface
* A line to represent the EJB’s remote interface
You should also include the following information on your diagram:
* The name of the EJB
* The type of EJB (session bean, entity bean, or message-driven bean)
* The EJB’s interfaces
* The EJB’s methods
