### 4. Regenerate Auto-Generated Java Classes

Fess uses DBFlute's LastaFlute FreeGen to automatically generate Java constants from property files.

Run the regeneration command:

```bash
# Option 1: Using Maven from project root
mvn dbflute:freegen

└── fess_indices/              # OpenSearch index mappings

src/main/webapp/WEB-INF/view/  # JSP templates
```

## DBFlute Code Generation

DBFlute generates type-safe data access code for OpenSearch indices:

```bash
mvn dbflute:freegen
```

Generated code:
- `opensearch/{index}/bsentity/` - Base entities (do not edit)
- `opensearch/{index}/exentity/` - Extended entities (customize here)
