Spring boot server and exe building

@rohitpatidar001

Having worked with Java and J2EE technologies for over 9 years, I have gained a deep understanding of the Spring Boot framework and how to build robust RESTful APIs. Specifically, I've honed my skills in handling distributed systems, designing clean data access patterns, ensuring APIs' security and validating them through automated testing. These capabilities make me a perfect fit for your project. Moreover, my experience with Docker, CI/CD pipelines, and AWS-based deployments uniquely position me to handle the server administration component of your project as well. I'll ensure that the external server is efficiently provisioned for your API's needs while maintaining its reliability and scalability. Additionally, I bring to the table extensive experience in integrating AI tools with backend services. This helps me optimize code quality, generate unit tests more effortlessly, and enhance developer productivity. Given this project's reliance on interdependent systems, such expertise guarantees precise executions and task deliveries. Partnering with me will properly align your vision with my skillset to get your Spring boot Jar to the expected external server format and an identical exe built just as you need it.

✋ Hi there. I can build your Spring Boot server that hits an external endpoint and returns the expected format, plus recreate your EXE with matching behaviour. ✔️ I have built ten mock servers in Spring Boot for API testing and also reversed engineered three EXE tools to replicate their exact logic and output. ✔️ I will code a Spring Boot REST controller that accepts calls from your jar, forwards requests to the external server, then reformats the response, and separately I will rebuild your EXE with the same inputs and outputs using C++ or C#. Let’s chat so you can share the API spec from your jar and a sample of what the existing EXE does. Mykhaylo

Hi, As per my understanding: You have two requirements: first, to build an external server that your Spring Boot JAR will call, which must return responses in the exact format expected; second, you want to replicate an existing EXE so it behaves the same for your use case. Implementation approach: For the first part, I will analyze the API requests from your Spring Boot app (endpoints, payloads, headers) and build a lightweight server (Node.js or Python/FastAPI) that mimics the external system, returning precise response formats and handling edge cases. It will be configurable and easy to deploy locally or on a VPS. For the second part, directly cloning an EXE is not always feasible without source access, but I can reverse-engineer its behavior (inputs/outputs, workflow) and rebuild an equivalent application that performs the same functions reliably. A few quick questions: 1. Do you have API request/response samples or logs? 2. Preferred language for the external server? 3. What exactly does the EXE do (inputs/outputs)? 4. Do you have permission/source details for the EXE? 5. Should the server handle authentication or just mock responses?

Hi I have checked the requirements and I want a bit more clarification. It would be good if we can discuss further about it. Best

@nadeemkhan7

Hi, The project hinges on two deliverables: a Spring Boot jar that proxies API calls to an external server and reformats responses exactly as expected, plus recreating an existing exe with identical behavior. Precision in request/response mapping and deterministic exe output are critical. Lets connect in chat so that we discuss further. Regards, Mohd Nadeem Khan

Hi, I’m a Java backend developer with strong experience in Spring Boot, API integrations, and system replication tasks, and I can handle both parts of your requirement. ✅ Relevant Expertise ✅ Java (8–21) & Spring Boot ✅ REST API development & mock/external server setup ✅ API request/response mapping ✅ Reverse engineering & replication logic ✅ Windows application understanding (EXE behavior analysis) ? How I Can Help Part 1: External Server (API Simulation) • Build a Spring Boot-based mock/external server • Replicate the expected request/response format • Ensure seamless communication with your existing JAR Part 2: EXE Replication • Analyze the existing EXE behavior • Recreate the same functionality in Java (or suitable approach) • Ensure it works exactly as required ✔ Deliverables ✔ External server with required API responses ✔ Working replica of EXE functionality ✔ Clean, maintainable code I focus on accurate integration, clean implementation, and reliable results. Ready to review your files and start immediately. Best regards, Abhay

@sanjaykumargupta

Hi, I can start working immediately on creating stub server to handle springboot request hit. We can discuss in detail. Regards Sanjay

@fizaa170

I’d set up a custom mock/external server to mirror the exact API contract your Spring Boot jar expects, plus analyze and recreate the EXE’s functionality so you get the same behavior in a controlled, scalable way. Can you share the API request/response format your jar sends and expects back? What does the EXE currently do step by step, and do you need it rebuilt or just replicated behavior? Best regards, Muzammil

@saadhey

Hi! I understand both parts of your project. For part one I'll build the external server that receives API calls from your Spring Boot jar and returns responses in exactly the format your application expects. For part two I'll need to see the original EXE to understand its functionality and replicate it properly. Share the API request and response format details and the EXE file and I can give you a precise timeline. Ready to start immediately!

@indreshpnk

Hello, I understand you need a Spring Boot based backend system where a Spring Boot JAR calls an external API server, and we also need to build a custom external server that returns data in the required format, along with a working EXE application with similar functionality. The goal is to deliver a reliable, well-structured, and scalable integration solution. Here’s what I can provide: • Development of external REST API server to handle incoming requests and return formatted responses as required • Proper request/response transformation layer to ensure compatibility with your Spring Boot JAR workflow • Creation of EXE application with packaged, standalone execution and same functional behavior I bring over 4+ years of experience in Java, Spring Boot, REST APIs, microservices, and backend architecture, with strong focus on performance, reliability, and clean system design across enterprise-level applications. Just to clarify a few things: • What exact response format is expected from the external server? • For the EXE, do you prefer Java-based packaging or another technology like C#/C++? Please come to the chat box to discuss more about your project. Best regards Indresh Kushwaha

Hi there, I can deliver both parts of your project efficiently. I have a strong background in backend architecture and API development, making this a perfect fit for my skill set. Part 1: The External Server (API Responder) Building a server to receive requests from your Spring Boot jar and return specifically formatted payloads is exactly the kind of backend work I do daily. I have extensive experience building scalable REST APIs and microservices using Java and Spring Boot. I can quickly set up this external server to process the incoming requests and return the exact JSON/XML formats your main application expects to keep your system running smoothly. Part 2: Replicating the .exe I understand you need an existing .exe replicated to perform the exact same functions. With my proficiency in C/C++ and Core Java, I can analyze the behavior, inputs, and outputs of your current executable. I will rebuild that core logic and compile it into a fresh, standalone .exe file that works perfectly for your use case. I am available to start immediately and my rate fits comfortably within your ₹750–₹1,250 INR/hour budget. Please feel free to message me so I can review the required API payload formats and take a look at the existing .exe file to get started. Best regards, Chhavi

@onenarendra

I can help you fix it but only if you can help me understand it clearly. I am sorry to say but whatever you explained here doesn't make sense. I have 8+ years exp in Java/Spring Boot, mostly building and fixing production APIs. I’ve handled broken REST endpoints, bad data flows, and legacy issues like this. Can quickly trace the root cause and stabilize your GET/POST calls. Happy to start with the first set and move fast.
