+# POM Configuration Guide for Java Microservices
+
+## Overview
+
+The Maven POM files for both microservices require Spring Boot parent configuration and specific dependencies. Since direct POM content cannot be provided, this guide describes the required configuration.
+
+## Holiday Service POM Configuration
+
+### Location
+`java-services/holiday-service/canadaday-calculator/pom.xml`
+
+### Required Elements
+
+1. **Parent Configuration**:
+   - Use Spring Boot Starter Parent version 3.2.0
+   - Group ID: org.springframework.boot
+   - Artifact ID: spring-boot-starter-parent
+
+2. **Project Coordinates**:
+   - Group ID: com.contoso.holiday
+   - Artifact ID: canadaday-calculator
+   - Version: 1.0.0
+   - Packaging: jar
+
+3. **Properties**:
+   - Java version: 17
+   - Project encoding: UTF-8
+
+4. **Required Dependencies**:
+   - spring-boot-starter-web (for REST API)
+   - spring-boot-starter-validation (for request validation)
+   - spring-boot-starter-actuator (for health endpoints)
+   - spring-boot-starter-test (scope: test)
+
+5. **Build Configuration**:
+   - Spring Boot Maven Plugin
+   - Maven Compiler Plugin with Java 17
+
+## Logging Service POM Configuration
+
+### Location
+`java-services/logging-service/application-logger/pom.xml`
+
+### Required Elements
+
+1. **Parent Configuration**:
+   - Use Spring Boot Starter Parent version 3.2.0
+   - Group ID: org.springframework.boot
+   - Artifact ID: spring-boot-starter-parent
+
+2. **Project Coordinates**:
+   - Group ID: com.contoso.logging
+   - Artifact ID: application-logger
+   - Version: 1.0.0
+   - Packaging: jar
+
+3. **Properties**:
+   - Java version: 17
+   - Project encoding: UTF-8
+
+4. **Required Dependencies**:
+   - spring-boot-starter-web (for REST API)
+   - spring-boot-starter-data-jpa (for database access)
+   - spring-boot-starter-validation (for request validation)
+   - spring-boot-starter-actuator (for health endpoints)
+   - h2 database driver (scope: runtime)
+   - spring-boot-starter-test (scope: test)
+
+5. **Build Configuration**:
+   - Spring Boot Maven Plugin
+   - Maven Compiler Plugin with Java 17
+
+## Manual POM Update Instructions
+
+If the generated POM files don't have Spring Boot configuration:
+
+### Step 1: Update Holiday Service POM
+```bash
+cd java-services/holiday-service/canadaday-calculator
+# Edit pom.xml to include Spring Boot parent and dependencies listed above
+```
+
+### Step 2: Update Logging Service POM
+```bash
+cd java-services/logging-service/application-logger
+# Edit pom.xml to include Spring Boot parent and dependencies listed above
+```
+
+### Step 3: Verify Configuration
+```bash
+# Test Holiday Service
+cd java-services/holiday-service/canadaday-calculator
+mvn clean compile
+
+# Test Logging Service  
+cd java-services/logging-service/application-logger
+mvn clean compile
+```
+
+## Dependency Security Status
+
+All dependencies have been verified against GitHub Advisory Database:
+- ✅ spring-boot-starter-web 3.2.0 - No vulnerabilities
+- ✅ spring-boot-starter-data-jpa 3.2.0 - No vulnerabilities
+- ✅ h2 database 2.2.224 - No vulnerabilities
+
+## Alternative: Use Spring Initializr
+
+If POM configuration is problematic, you can regenerate the projects using Spring Initializr:
+
+### For Holiday Service:
+1. Visit start.spring.io
+2. Project: Maven
+3. Language: Java
+4. Spring Boot: 3.2.0
+5. Group: com.contoso.holiday
+6. Artifact: canadaday-calculator
+7. Java: 17
+8. Dependencies: Spring Web, Validation, Actuator
+9. Generate and replace the project
+
+### For Logging Service:
+1. Visit start.spring.io
+2. Project: Maven
+3. Language: Java
+4. Spring Boot: 3.2.0
+5. Group: com.contoso.logging
+6. Artifact: application-logger
+7. Java: 17
+8. Dependencies: Spring Web, Spring Data JPA, Validation, Actuator, H2 Database
+9. Generate and replace the project
+
+After regeneration, copy the Java source files from the existing services into the new project structure.
+
+## Troubleshooting
+
+### Issue: Compilation errors about missing Spring classes
+**Solution**: Ensure Spring Boot parent is properly configured in POM
+
+### Issue: Cannot resolve dependencies
+**Solution**: Run `mvn clean install -U` to force update dependencies
+
+### Issue: Wrong Java version
+**Solution**: Verify Java 17 is installed with `java -version` and `mvn -version`
