# Eo / Web / Webview

## Overview

`eo.web.webview` appears to be a small web-view integration area that connects presentation state, screen logic, and framework configuration. The child documentation for `ACA001SF` suggests this package is less about rich domain behavior and more about wiring a view flow together: a bean carries data into the UI, a logic class provides the lifecycle entry point, and XML/JSP resources bind the pieces into a runnable screen.

Because there are no indexed source files, classes, or dependencies at the package level, the best evidence comes from the child module documentation and its referenced configuration files. Taken together, they show a configuration-driven webview area where the important behavior is defined by how components are linked rather than by complex Java code.

## Sub-module Guide

### `ACA001SF`

`ACA001SF` is the only documented child module under `eo.web.webview`, and it seems to represent a single screen or view flow.

From the child page, the module contains:

- `ACA001SFBean` — a minimal data holder with a single `value` property.
- `ACA001SFLogic` — an empty execution hook used by the screen lifecycle.
- Supporting XML and JSP resources that reference those classes.

The relationship between those parts is the key to understanding the module:

- The **bean** is the state carrier that presentation code can read.
- The **logic** class is the framework hook that gets invoked during screen execution.
- The **XML files** appear to wire the bean and logic together for one or more runtime scenarios.
- The **JSP** consumes the bean, which suggests the UI is the final consumer of the state exposed by the Java layer.

So `ACA001SF` is not a self-contained business-service module; it appears to be a webview fixture or screen implementation that demonstrates how the framework binds data and lifecycle logic together.

## Key Patterns and Architecture

### Configuration-driven screen wiring

The child documentation points to a pattern where runtime behavior is defined mostly in XML rather than in code. The logic class has an empty `execute()` method, which suggests the framework expects the class to exist and be callable even when it currently does nothing.

### Thin model, thin logic

The bean exposes only a single `String` value, and the logic class contains no business rules. This appears to indicate a deliberately lightweight screen model where the primary concern is integration shape, not computation.

### View contract over implementation detail

The package seems to function as a contract between configuration and presentation:

- XML resolves the bean and logic types.
- The JSP reads the bean state.
- The Java code keeps the API surface small and stable.

## Dependencies and Integration

At the package level, no external dependencies were resolved in the index. The integration points are instead the child module’s surrounding resources and framework conventions.

### Documented integration points from `ACA001SF`

The child page references these resources as consumers of the module’s classes:

- `WEBGAMEN_FULL_ACA001.xml`
- `WEBGAMEN_ACA001010PJP.xml`
- `x33S_ACA001.xml`
- `faces-config.xml`
- `FULL_ACA001010PJP.jsp`
- `external-refs.xml`

This suggests the module participates in a larger web application where:

- XML configuration selects the implementation classes.
- Faces or similar view configuration exposes the bean.
- The JSP renders the final UI.
- At least one external reference file is used to validate or resolve class wiring.

## Notes for Developers

- This module appears to be intentionally minimal, so changes should focus on preserving wiring compatibility rather than adding logic for its own sake.
- `ACA001SFBean` is likely part of the view contract. Even small API changes may ripple through XML and JSP references.
- The existence of two `ACA001SFLogic` source variants in the child documentation suggests the package may be used in resolution tests or fixture scenarios. That means naming and fully qualified class references matter.
- If you extend this area, keep in mind that the current shape looks framework-oriented: the important behavior may live in XML configuration and view resources rather than in Java methods.
