Getting Started with Java Hosting

Deploy your Java applications on ShardCloud with minimal configuration and maximum performance.
ShardCloud supports Java applications with automatic JAR execution and dependency management.

​
Prerequisites

Before uploading your Java application, ensure you have the following project structure ready.

Required Files

Essential files for deployment

Simple Structure

Clean deployment process

​
Required Files

Your Java application must include these two essential files:

​
1. Entry Point File

  • File: yourapp.jar
  • Purpose: Compiled Java application JAR file
  • Requirements: Must be a valid executable JAR with main class defined

​
2. Manifest Configuration

  • File: MANIFEST.MF
  • Purpose: Defines JAR metadata and dependencies
  • Requirements: Valid manifest format with Main-Class and dependency information

​
3. ShardCloud Configuration

  • File: .shardcloud
  • Purpose: Platform-specific deployment settings
  • Requirements: Plain text configuration file in root directory
.sharcloudd and the entrypoint file are required.

​
ShardCloud Configuration

The .shardcloud file configures your application deployment settings.

​
Configuration Example

DISPLAY_NAME=myfirstjavaproject
DESCRIPTION=a simple java application
MAIN=myapp.jar
MEMORY=1024
VERSION=LATEST
Java applications typically require more memory than interpreted languages. Choose appropriate memory allocation for your application’s needs.

​
