# Eo / Web

## Overview

`eo.web` appears to be a small web-integration layer whose main responsibility is to connect framework-driven page flow with presentation artifacts such as XML descriptors and JSP views. The available evidence suggests that this package does not contain much standalone business logic of its own. Instead, it serves as a naming and wiring surface where the surrounding web stack expects to find specific classes, beans, and logic hooks.

In practice, this makes `eo.web` a contract area: configuration files, JSP pages, and framework conventions refer to the classes in this package by exact name, and those references determine how pages are resolved and rendered.

## Sub-module Guide

### `webview`

The only documented child area is `webview`, which contains the concrete page-fixture example `ACA001SF`.

`webview` appears to represent the point where view-layer wiring is defined. Its child documentation shows two closely related roles:

- `ACA001SFBean` - a small data carrier that exposes a `value` property for the view layer
- `ACA001SFLogic` - an execution hook with an empty `execute()` method

The relationship between these pieces is configuration-driven. The logic class is the framework entry point that XML configuration can name and invoke, while the bean is the state object that JSP or related presentation files consume. This means the child module is less about business processing and more about demonstrating or supporting how the web framework binds named classes to a page flow.

The child page also mentions a second `ACA001SFLogic` source variant in `xml-unresolved-fqn`, which appears to exist to exercise alternate class-resolution behavior. That suggests `webview` is used not only for normal page wiring but also for testing how XML configuration behaves under different fully qualified name resolution conditions.

### How the child relates to the parent

`eo.web` is the broader package boundary, while `webview` is the concrete example of how that boundary is used. The parent provides the integration area; the child provides the named page components that external configuration and view files reference. In other words, the parent is the contract surface, and the child is one of the contract's implemented fixtures.

## Key Patterns and Architecture

### Configuration-first wiring

This area appears to be organized around external configuration rather than direct Java-to-Java calls:

1. XML config names a logic class.
2. The framework instantiates the class and calls `execute()`.
3. JSP or similar view artifacts consume the bean state.

This pattern makes the module useful as a fixture for framework integration, especially where the important behavior is selection by name rather than computation inside methods.

### Thin logic and thin data objects

The documented classes are intentionally minimal:

- `ACA001SFLogic` contains an empty `execute()` method
- `ACA001SFBean` exposes only a simple property surface

That structure indicates that the technical focus is on binding and resolution, not on algorithmic work. The module appears to verify that the web stack can locate the right class, create the right objects, and hand control to the correct view path.

### Dual-source resolution scenario

The duplicate logic class mentioned in `xml-unresolved-fqn` suggests a deliberate resolution test. One source tree appears to represent the normal fixture, and the alternate tree appears to represent a case where XML lookup does not resolve the fully qualified name in the same way. This makes `eo.web` useful for validating classpath and configuration edge cases as well as ordinary page flow.

## Dependencies and Integration

The evidence for this module shows no resolved package dependencies and no indexed source symbols beyond the documented child page. That points to a very light internal structure and a strong reliance on external integration points.

### External integration surfaces

Based on the child documentation, the main integrations are:

- XML configuration files that name `ACA001SFLogic` and `ACA001SFBean`
- JSP pages that consume `ACA001SFBean`
- framework mechanisms that invoke `execute()` on the configured logic class

The child page specifically references these consumers or related artifacts:

- [WEBGAMEN_FULL_ACA001.xml](full-fixture-codebase/src/java/eo/web/webview/ACA001SF/ACA001SFBean.java)
- [faces-config.xml](full-fixture-codebase/src/java/eo/web/webview/ACA001SF/ACA001SFBean.java)
- [WEBGAMEN_ACA001010PJP.xml](full-fixture-codebase/src/java/eo/web/webview/ACA001SF/ACA001SFBean.java)
- [x33S_ACA001.xml](full-fixture-codebase/src/java/eo/web/webview/ACA001SF/ACA001SFBean.java)
- [FULL_ACA001010PJP.jsp](full-fixture-codebase/src/java/eo/web/webview/ACA001SF/ACA001SFBean.java)
- [external-refs.xml](full-fixture-codebase/src/java/eo/web/webview/ACA001SF/ACA001SFLogic.java)

These links show that the package is meant to be consumed by exact class name, so packaging and naming stability matter more here than internal complexity.

## Notes for Developers

- Treat `eo.web` as a contract boundary. Renaming or relocating classes may break XML or JSP references even if compilation still succeeds.
- `ACA001SFBean` is currently minimal and read-focused. If additional state is needed, verify how the surrounding framework expects beans to be populated before adding behavior.
- `ACA001SFLogic` is empty in the documented fixture. That usually means the framework or configuration carries the real behavior, so inspect the XML and view files before assuming the class should contain logic.
- Because the child documentation includes an alternate `xml-unresolved-fqn` variant, be careful when debugging resolution issues. One source tree may be intended to model normal behavior while the other exists specifically to demonstrate lookup failure or ambiguity.
- When extending this area, prefer keeping the API surface stable and explicit. The surrounding system appears to depend on predictable names rather than on complex class relationships.
