Is there any OSLC service equivalent jars available in Spring boot application to communicate with IBM CLM & PLM applications?

I am not aware. You could try to look into the Eclipse Lyo project, if that could be reused.

To integrate with IBM CLM (Collaborative Lifecycle Management) and PLM (Product Lifecycle Management) applications using OSLC (Open Services for Lifecycle Collaboration) in a Spring Boot application, there are several options you can consider. While there may not be specific "OSLC service equivalent jars" tailored exclusively for Spring Boot, you can utilize existing libraries and frameworks that support OSLC. One notable option is the Eclipse Lyo project, which provides SDKs for OSLC. This project includes consumer and provider SDKs primarily for Java, which can be integrated into your Spring Boot application. You can find these resources on the Eclipse Lyo GitHub page or their official website. Additionally, you might want to explore other open-source projects that facilitate OSLC integration, as they can offer valuable tools and examples for your implementation. If you're upgrading from a Java application, it would be beneficial to check the compatibility of existing libraries with Spring Boot and potentially adapt your current codebase to leverage Spring's features, such as dependency injection and RESTful services. While there may not be direct equivalents to the jars you used previously, adapting your application using available OSLC resources should enable effective communication with IBM CLM and PLM applications.
