# Eo / Web / Webview

## Overview

`eo.web.webview` appears to be the web-view integration area for the Eo application. Based on the child documentation available in this area, it is responsible for wiring a screen-level bean and a screen logic class into the surrounding web framework and JSP view layer.

This module does not expose a broad service or domain API. Instead, it seems to represent a small, framework-driven presentation slice: request handling enters through configuration, logic is invoked through a screen action, and a bean supplies the view state that the JSP renders.

## Sub-module Guide

### [`ACA001SF`](.codewiki/eo/web/webview/ACA001SF.md)

`ACA001SF` is the only documented child module under `eo.web.webview`. It looks like a thin screen implementation with two internal parts:

- `ACA001SFBean` supplies a simple string value to the UI.
- `ACA001SFLogic` provides the `execute()` entry point used by the framework.

The relationship between them is not that one calls the other directly, but that they work together through the web framework and view wiring. The bean carries renderable state, while the logic class acts as the action hook that prepares or advances the screen flow. The child documentation also shows that both classes are referenced from the JSP and XML configuration, which suggests the module is assembled through external wiring rather than internal orchestration code.

## Key Patterns and Architecture

The architecture in this area appears to follow a classic screen-module pattern:

1. A web request is routed by XML configuration.
2. The framework invokes a logic class as the screen action.
3. A bean object provides the data exposed to the JSP.
4. The JSP reads the bean and renders the screen.

This pattern keeps the view model separate from the executable hook. The code shown in the child module is intentionally sparse, so the important design decision is not algorithmic complexity but separation of responsibilities:

- **Bean** for presentation state
- **Logic** for lifecycle entry point
- **XML and JSP** for integration and rendering

This appears to be a framework-oriented design where the module's behavior is defined as much by configuration as by Java source.

## Dependencies and Integration

The indexed evidence for this parent module shows no direct package dependencies, no captured source files, and no resolved cross-module relationships at the package level. That means the integration surface is mostly external and implicit.

From the child documentation, the important integration points are:

- [`WEBGAMEN_FULL_ACA001.xml`](WEBGAMEN_FULL_ACA001.xml) — configuration that wires the bean and logic class into the web flow
- [`FULL_ACA001010PJP.jsp`](FULL_ACA001010PJP.jsp) — the JSP view that consumes the screen state

So while `eo.web.webview` itself is small, it connects the broader web application by acting as the package that hosts screen-specific wiring artifacts.

## Notes for Developers

- This area appears to be screen-oriented rather than domain-oriented. Changes here should be checked against the JSP and XML wiring, not just the Java classes.
- The documented child module is very minimal, so framework conventions likely matter more than local implementation details.
- `ACA001SFLogic.execute()` currently has no visible behavior, so if this screen needs to do real work, that behavior will need to be added deliberately.
- `ACA001SFBean` exposes a read-only value in the documented source, so look for framework binding or construction paths if you need to understand where its state comes from.
- Because the parent package has no other documented children, this module currently reads as a narrow integration surface rather than a reusable subsystem.
