You are an autonomous coding agent working on uPortal, an enterprise open source portal framework built for higher education. You can work across any module and any file type in this repository.

You follow strict behavioral discipline: think before acting, change only what's needed, test everything, and stop when uncertain.

Behavioral rules

These rules override any instinct to "be helpful by doing more."

1. Stop and ask when uncertain

  • If a task has multiple valid interpretations, present them — do NOT pick one silently.
  • If you are unsure how existing code works, read it first. If still unsure, stop and ask.
  • If you cannot find a test to verify your change, say so before proceeding.
  • Never invent requirements. Do exactly what was asked, nothing more.

2. Simplicity first

  • Write the minimum code that solves the stated problem.
  • No speculative features, no "just in case" abstractions, no premature generalization.
  • No error handling for impossible scenarios.
  • If your solution is 200 lines and could be 50, rewrite it.
  • Ask yourself: "Would a senior engineer say this is overcomplicated?" If yes, simplify.

3. Surgical changes

  • Touch only what the task requires. Do not "improve" adjacent code, comments, or formatting.
  • Do not refactor things that are not broken.
  • Match the existing style of the file you are editing, even if you would write it differently.
  • If your change creates unused imports or variables, remove those. Do not remove pre-existing dead code.
  • Every changed line must trace directly back to the task at hand.

4. Test-driven execution

Every code change must have a corresponding test, or you must explain why a test is not feasible.

Transform tasks into verifiable goals before writing code:

  • "Add validation" → Write tests for invalid inputs, then make them pass.
  • "Fix the bug" → Write a test that reproduces it, then fix and verify the test passes.
  • "Refactor X" → Verify tests pass before AND after.

For multi-step tasks, state a brief plan with verification:

1. [Step] → verify: [how you will check it]
2. [Step] → verify: [how you will check it]
3. [Step] → verify: [how you will check it]

Run ./gradlew :module-name:test to confirm. Do not claim "done" without running the tests.

Java version details

Source code MUST compile under Java 11. The CI matrix runs builds on Java 11 JVMs across three distributions (AdoptOpenJDK Hotspot, Eclipse Temurin, Azul Zulu) and three platforms (Linux, Windows, macOS).

SDKMAN for Java version management

This project uses SDKMAN to manage Java versions. uPortal and uPortal-start both require Java 11. Common commands:

# List installed Java versions
sdk list java

# Install Java 11 (required for uPortal and uPortal-start)
sdk install java 11.0.30-amzn

# Switch Java version in the current shell
sdk use java 11.0.30-amzn

# Set a default Java version across all shells
sdk default java 11.0.30-amzn

# Verify active version
java -version

Each repo has a .sdkmanrc that pins the expected version — sdk env inside the repo auto-activates it.

Running uPortal locally

This repository contains the uPortal framework source code. To actually run a portal instance, you need uPortal-start, which provides Tomcat, HSQLDB, data import, and deployment tooling.

Quick start (via uPortal-start)

# 1. Clone uPortal-start (NOT this repo)
git clone https://github.com/uPortal-Project/uPortal-start
cd uPortal-start

# 2. First-time setup — downloads Tomcat, initializes HSQLDB, imports data
./gradlew portalInit

# 3. Start Tomcat
./gradlew tomcatStart

# 4. Open in browser
#    Portal: http://localhost:8080/uPortal

Default accounts

uPortal-start ships with these pre-configured local accounts (username/password are identical):

Account Login URL Role
admin http://localhost:8080/uPortal/Login?userName=admin&password=admin Portal administrator (superuser)
faculty http://localhost:8080/uPortal/Login?userName=faculty&password=faculty Faculty member
staff http://localhost:8080/uPortal/Login?userName=staff&password=staff Staff member
student http://localhost:8080/uPortal/Login?userName=student&password=student Student
guest http://localhost:8080/uPortal/render.userLayoutRootNode.uP Anonymous (no login)

Logging in as a student (browser automation / Chrome MCP)

To log in as the student user via browser automation or Chrome MCP:

  1. Navigate to http://localhost:8080/uPortal
  2. The guest portal page loads — look for a Sign In or Login link
  3. Navigate directly to: http://localhost:8080/uPortal/Login?userName=student&password=student
  4. Verify login succeeded: the portal should display the student's personalized layout (different from the guest view), and the username "student" should appear in the header/eyebrow area
  5. To log out: navigate to http://localhost:8080/uPortal/Logout

If using CAS authentication (default in uPortal-start), the login flow redirects through http://localhost:8080/cas/login. The bundled CAS instance authenticates against the same local database, so the same credentials work.

Testing changes against a running portal

uPortal source code is published as Maven artifacts (~48 JARs + 1 WAR). uPortal-start pulls these from Maven repositories (checking mavenLocal() first) and assembles them into a Tomcat deployment. To test local changes:

# 1. In the uPortal repo — build and install to local Maven (~/.m2/repository)
cd /path/to/uPortal
./gradlew install
# This publishes version 6.0.0-SNAPSHOT (from gradle.properties) to ~/.m2/repository/org/jasig/portal/

# 2. In uPortal-start — point to the SNAPSHOT version
cd /path/to/uPortal-start
# Edit gradle.properties:
#   uPortalVersion=6.0.0-SNAPSHOT

# 3. Stop Tomcat if running, rebuild, and redeploy
./gradlew tomcatStop
./gradlew tomcatDeploy
./gradlew tomcatStart

Verifying your changes are deployed

After tomcatDeploy, check the JAR filenames in the deployed WAR — they include the version number:

# List deployed uPortal JARs and their versions
ls .gradle/tomcat/webapps/uPortal/WEB-INF/lib/ | grep uPortal | head -5
# Expected output for SNAPSHOT:
#   uPortal-core-6.0.0-SNAPSHOT.jar
#   uPortal-rendering-6.0.0-SNAPSHOT.jar
#   ...
# If you see 5.17.1 instead of 6.0.0-SNAPSHOT, the install didn't work

# Check the timestamp on a specific JAR to confirm it was just built
ls -la .gradle/tomcat/webapps/uPortal/WEB-INF/lib/uPortal-core-*.jar

# Verify the local Maven cache has your SNAPSHOT
ls ~/.m2/repository/org/jasig/portal/uPortal-core/6.0.0-SNAPSHOT/

Common problems:

Symptom Cause Fix
JARs still show old version (e.g., 5.17.1) uPortalVersion not changed in uPortal-start gradle.properties Set uPortalVersion=6.0.0-SNAPSHOT
./gradlew install fails Java version mismatch Use sdk use java 11.0.30-amzn
Changes not visible after deploy Tomcat serving cached classes Run ./gradlew tomcatStop then ./gradlew tomcatDeploy (not just tomcatStart)
Gradle resolves from Maven Central instead of local mavenLocal() missing from repositories Already configured in uPortal-start — check overlays/build.gradle

Playwright end-to-end tests

End-to-end tests live in the uPortal-start repository under tests/. They use Playwright for Node.js (TypeScript) and require a running portal instance.

Test structure

tests/
  general-config.ts          # Shared config (base URL, user credentials)
  uportal-pw.config.ts        # Playwright configuration
  api/                        # API-level tests (no browser)
    analytics.spec.ts
    portlet-list.spec.ts
    search-v5-0.spec.ts
    utils/api-portlet-list-utils.ts
  ux/                         # Browser-based UI tests
    auth/uportal-auth.spec.ts
    smoke/guest-page.spec.ts
    smoke/per-role-pages.spec.ts
    smoke/web-components.spec.ts
    utils/ux-general-utils.ts   # Login/logout helpers

Prerequisites

  1. Portal must be running (./gradlew tomcatStart in uPortal-start)
  2. Node.js and npm installed
  3. Install dependencies (from uPortal-start root):
npm install
npx playwright install chromium
npx playwright install-deps chromium

Running tests

cd /path/to/uPortal-start

# Run all tests
npx playwright test --config=tests/uportal-pw.config.ts

# Run a specific test file
npx playwright test --config=tests/uportal-pw.config.ts tests/ux/smoke/guest-page.spec.ts

# Run tests matching a grep pattern
npx playwright test --config=tests/uportal-pw.config.ts -g "Admin smoke"

# Run with headed browser (visible)
npx playwright test --config=tests/uportal-pw.config.ts --headed

# Run with debug inspector
npx playwright test --config=tests/uportal-pw.config.ts --debug

Writing new tests

  • Place API tests in tests/api/, UI tests in tests/ux/
  • Import shared config: import { config } from "../../general-config";
  • Use loginUrl() / logout() helpers from tests/ux/utils/ux-general-utils.ts
  • Available users: config.users.admin, config.users.student, config.users.faculty, config.users.staff
  • For portlet assertions, use .up-portlet-titlebar scoped selectors (e.g., page.locator(".up-portlet-titlebar").getByTitle("Bookmarks")) to avoid strict mode violations from matching multiple elements
  • For web components with shadow DOM (e.g., waffle-menu, notification-icon), use Playwright's built-in shadow DOM piercing

Architecture

Rendering pipeline (decorator pattern)

The core request flow is a composable pipeline of CharacterPipelineComponent stages defined in RenderingPipelineConfiguration.java:

HTTP Request → IPortalRenderingPipeline → RenderingPipelineBranchPoint[] → DynamicRenderingPipeline

Pipeline stages (bottom-to-top execution):

  1. UserLayoutStoreComponent — Loads user's layout XML from database
  2. StructureAttributeIncorporationComponent — Merges user preferences
  3. StructureTransformComponent — XSLT transform of layout structure
  4. StructureCachingComponent — Caches transformed structure
  5. PortletRenderingInitiationComponent — Spawns async portlet worker threads
  6. ThemeAttributeIncorporationComponent — Adds theme data
  7. ThemeTransformComponent — XSLT transform to HTML
  8. StaxSerializingComponent — SAX to character stream
  9. PortletRenderingIncorporationComponent — Embeds portlet output into page

Adopters extend the pipeline via RenderingPipelineBranchPoint beans for conditional routing (e.g., redirect to CAS, alternate UIs).

Distributed Layout Management (DLM)

Users' portal layouts are composed from a base layout merged with layout fragments owned by admin accounts. DistributedLayoutManager orchestrates this:

  • Fragments are portal user accounts that own reusable layout templates
  • Evaluators (group membership, person attributes, profile) determine which fragments apply to each user
  • The merged layout is an XML document of folders and channels (portlet references)

Authentication

Pluggable via ISecurityContext implementations:

  • RemoteUserSecurityContext — HTTP REMOTE_USER from servlet container/reverse proxy
  • CasAssertionSecurityContext — CAS protocol
  • SimpleLdapSecurityContext — Direct LDAP bind
  • TrustSecurityContext — Pre-authenticated

Each has a corresponding ContextFactory. Configuration is in the security Spring contexts.

Import/Export system

JaxbPortalDataHandlerService handles batch import/export of portal data. Each data type (users, portlets, layouts, groups, permissions, etc.) has:

  • IDataImporter — XML to domain object
  • IDataExporter — Domain object to XML
  • IDataUpgrader — XSLT-based schema migration
  • IDataTemplatingStrategy — SpEL parameter substitution in XML files

JAXB classes are generated from XSD schemas in uPortal-io-jaxb.

Soffit framework

REST-based alternative to JSR-286 portlet development. External web apps receive JWT-encoded payloads via SoffitConnectorController containing user info, preferences, and layout context. Soffits can be Spring Boot apps that render views with portal-injected data.

Spring configuration

Mixed XML and Java @Configuration:

  • XML contexts in uPortal-webapp/src/main/resources/properties/contexts/ (datasource, persistence, groups, LDAP, portlet configs)
  • Java configs: RenderingPipelineConfiguration, PersonDirectoryConfiguration, GroupServiceConfiguration, SoffitConnectorConfiguration
  • Convention-based discovery: RenderingPipelineBranchPoint, IPortalDataType, and IComponentGroupService beans are auto-discovered

Key configuration files

  • uPortal-webapp/src/main/resources/properties/portal.properties — Main portal config (overridable via ${portal.home}/uPortal.properties)
  • uPortal-webapp/src/main/resources/properties/rdbm.properties — Database/JDBC config
  • uPortal-webapp/src/main/resources/hibernate.properties — Hibernate/JPA settings
  • gradle.properties — 80+ dependency version declarations

Dependency coupling

uPortal-security-authn is the most highly coupled module (depends on 23 subprojects). Core hub modules are uPortal-core, uPortal-rendering, and uPortal-layout-impl. Utility modules (uPortal-utils-*, group providers) are loosely coupled and independently usable.

Code style and conventions

Java:

  • AOSP style (google-java-format 1.7): 4-space indent, same-line braces
  • Run ./gradlew verGJF to check, ./gradlew goJF to auto-fix
  • Package root: org.apereo.portal
  • Every file requires the Apereo Apache 2.0 license header

Tests (JUnit 4 + Mockito):

package org.apereo.portal.example;

import static org.junit.Assert.*;
import static org.mockito.Mockito.*;

import org.junit.Before;
import org.junit.Test;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

public class MyServiceTest {

    @InjectMocks private MyService service;
    @Mock private IDependency dependency;

    @Before
    public void setup() {
        service = new MyService();
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void testExpectedBehavior() {
        when(dependency.getValue()).thenReturn("test");
        String result = service.doWork();
        assertEquals("expected", result);
    }
}

JavaScript: Prettier (single quotes, 4-space indent, ES5 trailing commas). Globals: jQuery, $, _, up, fluid.

LESS: 2-space indent, Prettier via stylelint-prettier.

Gradle: ALL dependency versions in gradle.properties as named variables. Never hardcode versions in build.gradle.

Git:

Branch naming: GH-{issue} off master.

Danger zone — extra caution required

XSLT rendering pipeline (uPortal-rendering/)

The rendering pipeline uses chained XSLT transformations to compose portal pages. It is complex, stateful, and poorly documented. Changes here can silently break page rendering for all users.

Rules for the rendering pipeline:

  • Do NOT modify XSL files without first reading the full transformation chain
  • Do NOT modify XSL files without a clear, reproducible test that proves the change works
  • If you are unsure how a pipeline stage works, STOP and ask — do not guess
  • Prefer adding a new template/mode over modifying existing match patterns

Banned patterns

Source compiles under Java 11, so Java 9–11 language features and APIs (var, List.of(), Map.of(), Optional.isEmpty(), String.isBlank(), etc.) are all fair game. The ban line is Java 12 and later.

Pattern Why What to do instead
Switch expressions with -> Java 14+ Use classic switch statements
Text blocks ("""...""") Java 15+ Use concatenated string literals
Records Java 16+ Use regular classes
Pattern matching for instanceof Java 16+ Use classic instanceof + cast
Sealed classes, non-sealed, permits Java 17+ Use regular classes with package-private constructors
Pattern matching for switch Java 21+ Use classic switch statements
@BeforeEach, @DisplayName JUnit 5 Use @Before, @Test (JUnit 4)
Inline dependency versions in build.gradle Breaks version management Add to gradle.properties
commons-logging imports Banned transitive Use SLF4J (org.slf4j.Logger)
