Java-John-RSPS is a custom 317 build made for the MoparScape client. It is made for people who want a simple RuneScape private server style setup on Windows. The project keeps the old-school feel and uses a setup that is easy to start from a GitHub page.
This guide shows you how to get the files, open the app, and run it on a Windows PC with no coding knowledge.
Use this page to download the project:
Open Java-John-RSPS download page
- Open the link above in your web browser.
- Look for the green or blue download option on the GitHub page.
- Save the files to a folder you can find again, such as
DownloadsorDesktop. - If the files come in a ZIP folder, keep it in that folder until you are ready to open it.
This app is built for Windows and runs best on a normal desktop or laptop.
You should have:
- Windows 10 or Windows 11
- At least 2 GB of free disk space
- A stable internet connection
- Java installed on your computer
- A mouse and keyboard
For best results, use a standard user account that can open downloaded files and install basic software.
Before you run Java-John-RSPS, make sure you have:
- The downloaded project files
- Java installed on Windows
- A folder ready for the game files
- A web browser like Chrome, Edge, or Firefox
If Windows asks what to do with the file, choose the option that keeps the file or opens it with Java.
Follow these steps in order:
- Open the download page and get the project files.
- Save the files to a known folder.
- If the download is a ZIP file, right-click it and choose Extract All.
- Open the extracted folder.
- Look for a file that starts the client or server, such as a
.jar,.bat, orrunfile. - Double-click the startup file.
- If Windows shows a prompt, choose Run or Allow.
- Wait for the client to load.
- If the game asks for a world, login, or host, use the default setup provided in the folder.
If Java is not already on your PC, install it first.
- Open your browser.
- Search for the latest Windows Java download from a trusted source.
- Download the Windows installer.
- Open the installer and follow the prompts.
- Finish the setup and restart your browser or computer if needed.
After Java is installed, return to the Java-John-RSPS folder and try the startup file again.
Once the files are ready, do this:
- Open the folder where you saved the project.
- Find the file that starts the client.
- Double-click it.
- Wait for the game window to appear.
- If the client does not open, try right-clicking the file and choosing Open.
If you see a black window first, that is normal for many Java game clients. Keep it open while the game starts.
The download may include a few file types:
.jar— a Java app file.bat— a Windows start file.txt— a text file with setup tips.zip— a compressed folder- folders such as
data,cache, orsrc
If you see a .bat file, that is often the easiest way to start the app on Windows.
Java-John-RSPS is built around a classic RSPS setup with a 317-style client. Common parts of this type of build include:
- Old-school RuneScape-style interface
- MoparScape client support
- Basic login and game world setup
- Simple file layout for local use
- Private server build structure
- Support for standard RSPS content
- Easy folder-based startup on Windows
The project name and topics suggest a build meant for people who like older private server clients and want a direct setup without extra steps.
After you extract the files, you may see a structure like this:
client/for the game clientserver/for server filescache/for game dataconfig/for settingsREADME.mdfor basic info
If the folder names differ, look for the file that matches the startup action, such as Run, Start, or Launch.
Try these steps if nothing happens:
- Check that Java is installed.
- Make sure you extracted the ZIP file.
- Try a different startup file in the folder.
- Right-click the file and choose Open.
- Move the project to a simple path like
C:\Java-John-RSPS. - Avoid folder names with special symbols.
If the game still does not start, close other apps and try again.
Keep these simple habits in mind:
- Only use files from the download page you trust.
- Save the files in one folder.
- Do not rename files unless the setup guide says to.
- Do not move parts of the cache or client by themselves.
- Keep a copy of the original ZIP file.
These steps help prevent broken paths and missing files.
