# Eo / Web / Webview

## Overview

`eo.web.webview` appears to be a small view-layer integration package for web screens under the Eo application. Based on the available child documentation, this area is responsible for providing the Java-side types that XML and JSP configuration bind to when a web view is rendered or executed.

The package does not show evidence of business rules, persistence, or rich orchestration of its own. Instead, it seems to act as a compatibility layer between the framework’s configuration files and the screen-specific classes used by the UI.

## Sub-module Guide

### `ACA001SF`

The only documented child module is `ACA001SF`, which appears to represent a single screen or feature slice. It provides two main types:

- `ACA001SFBean` — a minimal backing bean that exposes a `value` property through `getValue()`.
- `ACA001SFLogic` — a logic entry point with an `execute()` method that currently does nothing.

Taken together, these classes look like the screen contract for a simple page flow:

- the logic class gives the framework a named executable hook,
- the bean provides a tiny presentation model,
- XML and JSP files outside this package bind the two into the request/rendering pipeline.

The documentation also shows a second `ACA001SFLogic` source-set variant under `xml-unresolved-fqn`, which suggests this module is also used to validate fully qualified name resolution across source roots. That makes `ACA001SF` more than just a page implementation; it also seems to serve as a configuration wiring test case.

### How the pieces relate

The child module documentation implies a one-way dependency pattern:

- configuration references the logic class by name,
- the framework invokes `execute()`,
- the JSP/view layer reads from `ACA001SFBean`,
- the bean and logic remain intentionally minimal so the surrounding XML can control behavior.

In other words, the module is shaped by external wiring rather than internal composition.

## Key Patterns and Architecture

A few patterns show up consistently in the child documentation:

- **Convention over implementation** — the classes exist primarily so framework configuration can resolve stable names and types.
- **Thin view model** — the bean exposes only a single string property, suggesting the view contract is intentionally narrow.
- **No-op logic hook** — `execute()` is present but empty, which strongly suggests the real behavior is supplied by the framework lifecycle or by configuration-driven flow rather than in-class code.
- **Configuration-centered design** — the important relationships live in XML and JSP files outside this package, not in Java dependencies within it.

### Interaction diagram

    Config["XML configuration"] --> Logic["ACA001SFLogic"]
    Logic --> Execute["execute()"]
    Bean["ACA001SFBean"] --> View["JSP rendering"]
    Config --> Bean
    View --> Config
```

This appears to describe a screen flow where configuration selects the logic class, the logic provides an execution entry point, and the bean carries the display value into the page layer.

## Dependencies and Integration

The code analysis for this package shows no indexed source files, no captured classes, and no resolved package dependencies at the package level. That means the integration story must be inferred from the child documentation rather than from direct code references.

From the child page, the package connects to the wider system through configuration and views:

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

These references suggest that the webview layer is tied into several XML configuration paths and at least one JSP page. The repeated use of the same bean and logic names across multiple files implies shared wiring conventions across the application.

## Notes for Developers

- This package appears to be framework-facing. When changing class names, property names, or method signatures, check every XML and JSP reference first.
- `ACA001SFBean` currently exposes only `getValue()`. If you extend the bean, verify that the surrounding binding framework can populate any added properties.
- `ACA001SFLogic.execute()` is empty, so do not assume behavior belongs here unless you have confirmed it in the calling framework or config.
- The presence of a duplicate `ACA001SFLogic` in another source set suggests this package may also participate in resolution tests. Keep variants aligned unless the divergence is intentional.
- Because this module is small and configuration-driven, changes here can have outsized effects on page wiring even when the Java diff looks minimal.
