codemap-jsp 0.4.0

JavaServer Pages (.jsp) indexer plugin for CodeMap (https://github.com/qxbyte/codemap)

codemap-jsp

A JavaServer Pages (.jsp) indexer for CodeMap, distributed as an independent PyPI package. Targets legacy Java web projects that still ship .jsp views.

What it captures

JSP files are HTML containers with embedded Java. The indexer scans five top-level constructs:

JSP construct	Captured as
<%@ page import="..." %>	extra.jsp_imports on the page symbol
<%@ include file="..." %>	extra.jsp_includes on the page symbol
<%! ... %> (declaration block)	Java members parsed by tree-sitter-java; methods → method, fields → variable, nested classes → class
<% ... %> (scriptlet)	Skipped — scriptlet locals are per-request state, not a stable interface
<form action="..." method="..."/> and <a href="...">	extra.http_client_calls on the page symbol — consumed by the host's http_route bridge to link the page to its server controller

Every JSP file produces one page-level pseudo-class symbol plus zero or more member symbols from any <%! ... %> blocks. The page name is derived from the file basename (UserList.jsp → UserList).

Why this matters for AI agents on legacy projects

A typical Spring MVC + JSP project has:

src/main/java/com/example/UserController.java
  @PostMapping("/api/users") void create(User u) { ... }

src/main/webapp/WEB-INF/views/users.jsp
  <form action="/api/users" method="POST"> ... </form>

The http_route bridge ships in codemap-core. Once both files are indexed, the bridge sees:

• the server route (POST, /api/users) exposed by UserController.create
• the client call (POST, /api/users) advertised by users.jsp

…and adds a calls edge from the page to the controller. AI agents can now answer "what JSP pages submit to this controller?" with a single codemap callers query — no grepping HTML for URLs.

Install

pip install codemap-jsp

tree-sitter-java is a hard dependency (used to parse declaration blocks). No tree-sitter-jsp grammar is needed.

SymbolID encoding

scip-jsp . . . src/main/webapp/views/UserList.jsp/UserList#tag().
└──────┘     └──────────────────────────────────────────────────┘
  scheme         path / page pseudo-class / member

Tests

pip install -e ".[dev]"
pytest

Limits / next steps

• Scriptlet (<% ... %>) bodies are not indexed for symbol extraction — they would surface per-request locals as noise. A future v0.2.x could optionally extract control-flow shape from scriptlets to support cross-page navigation.
• JSTL tags (<c:if>, <c:forEach>) and EL expressions (${...}) are not parsed. A codemap-jstl companion plugin could surface declared <c:set var="..."/> variables if there's demand.
• Tag files (.tag / .tagx) are supported on the same code path as pages but their unique <%@ attribute name="..." %> directives are not yet surfaced as individual symbols.
