# Eo / Web / Webview / Aca001sf

## Overview

The `ACA001SF` package is a JavaServer Faces (JSF) webview subpackage within the `eo.web` module. It provides the backing bean and view logic classes used to serve an ACA001-related JSP view in the application. The classes defined here are wired into the JSF lifecycle through `faces-config.xml` and referenced by multiple XML config files and JSP views.

## Key Classes and Interfaces

### ACA001SFBean

**Source:** [`ACA001SFBean.java`](full-fixture-codebase/src/java/eo/web/webview/ACA001SF/ACA001SFBean.java)

`ACA001SFBean` is a standard JSF backing bean (managed bean). It follows the classic JavaBeans pattern with a single field:

- **Field:** `private String value` — a simple string property.
- **Getter:** `getValue()` — returns the `value` field. This is the only accessor exposed, which means the JSP/view can bind to `#{aca001sfBean.value}` to display or read this property.

There is no setter, meaning the value is intended to be set internally (or via logic) and read by the view, rather than bound bidirectionally by user input.

This bean is referenced by:
- `faces-config.xml` (managed bean registration)
- `WEBGAMEN_FULL_ACA001.xml`
- `WEBGAMEN_ACA001010PJP.xml`
- `x33S_ACA001.xml`
- `FULL_ACA001010PJP.jsp` (view binding)

### ACA001SFLogic

**Source (full-fixture):** [`ACA001SFLogic.java`](full-fixture-codebase/src/java/eo/web/webview/ACA001SF/ACA001SFLogic.java)  
**Source (xml-unresolved-fqn):** [`ACA001SFLogic.java`](xml-unresolved-fqn/src/java/eo/web/webview/ACA001SF/ACA001SFLogic.java)

`ACA001SFLogic` is a view logic class with a single public method:

- **Method:** `execute()` — returns `void`. The method body is currently empty in both codebase variants. The full-fixture version includes a Javadoc comment: `/** ACA001SFLogic — Futurity view logic */`, which indicates this class serves as the controller/backing logic for a "Futurity" view associated with the ACA001 flow.

This class is referenced by:
- `WEBGAMEN_FULL_ACA001.xml`
- `WEBGAMEN_ACA001010PJP.xml`
- `x33S_ACA001.xml`
- `FULL_ACA001010PJP.jsp`
- `external-refs.xml`

## How It Works

This module follows the standard JSF / MVC pattern:

1. **Request arrives** — A JSP view (e.g., `FULL_ACA001010PJP.jsp`) requests the ACA001SF page.
2. **Bean lookup** — The JSF framework resolves `ACA001SFBean` via its registration in `faces-config.xml` or via XML config files like `WEBGAMEN_FULL_ACA001.xml`.
3. **Logic execution** — `ACA001SFLogic.execute()` is called as the view's logic entry point. In the current implementation, the method body is empty, suggesting it is a scaffold or placeholder for business logic yet to be added.
4. **View rendering** — The JSP reads properties from `ACA001SFBean` (e.g., `getValue()`) to render the page.

The fact that the same logical module appears in two source trees (`full-fixture-codebase` and `xml-unresolved-fqn`) with slightly different Javadoc coverage suggests one is the canonical definition and the other is a mirror or resolution target used by a build or documentation pipeline.

## Data Model

This module has a minimal data model:

| Class | Property | Type | Description |
|-------|----------|------|-------------|
| `ACA001SFBean` | `value` | `String` | A single string property exposed via `getValue()`. Likely used to pass a display value to the JSP view. |

No entities, DTOs, or additional data structures are defined within this package.

## Dependencies and Integration

### Outbound package dependencies
This package declares no internal package dependencies — it does not import or reference any other classes from within the `eo.web` hierarchy.

### Inbound dependencies (who uses this module)

| Consumer | Referenced Classes |
|----------|-------------------|
| `WEBGAMEN_FULL_ACA001.xml` | `ACA001SFBean`, `ACA001SFLogic` |
| `WEBGAMEN_ACA001010PJP.xml` | `ACA001SFBean`, `ACA001SFLogic` |
| `x33S_ACA001.xml` | `ACA001SFBean`, `ACA001SFLogic` |
| `FULL_ACA001010PJP.jsp` | `ACA001SFBean`, `ACA001SFLogic` |
| `faces-config.xml` | `ACA001SFBean` |
| `external-refs.xml` | `ACA001SFLogic` |

The module is a leaf in the `eo.web.webview` package hierarchy with no child subpackages.

## Notes for Developers

- **Empty logic method:** `ACA001SFLogic.execute()` currently has an empty body. If you are extending this module, this is the method where view-side business logic should be implemented.
- **Immutable bean property:** `ACA001SFBean` exposes only a getter for `value` — there is no setter. If you need to set the value from outside, add a corresponding setter method.
- **JSF naming convention:** The bean name likely maps to a JSF expression like `#{aca001sfBean}` (lowercase first letter, camelCase). This convention is controlled by the JSF configuration in `faces-config.xml`.
- **Multiple source tree presence:** The class `ACA001SFLogic` exists in both `full-fixture-codebase` and `xml-unresolved-fqn`. These may be synchronized artifacts from different build configurations. Be aware of which source tree you are editing and whether changes need to be propagated.
