Code Identification

In all source files (namely in the groupIds of the POMs), replace GXX with your group identifier. The group identifier consists of either A or T followed by the group number - always two digits. This change is important for code dependency management, to ensure your code runs using the correct components and not someone else's.

Getting Started

The overall system is made up of several modules. The main server is the DistLedgerServer. The clients are the User and the Admin. The definition of messages and services is in the Contract. The future naming server is the NamingServer.

See the Project Statement for a complete domain and system description.

Prerequisites

The Project is configured with Java 17 (which is only compatible with Maven >= 3.8), but if you want to use Java 11 you can too -- just downgrade the version in the POMs.

To confirm that you have them installed and which versions they are, run in the terminal:

javac -version
mvn -version

Installation

To compile and install all modules:

mvn clean install

How to run the project

1. Open namingServer in its directory

mvn compile exec:java

2. Open both server in different terminals

mvn compile exec:java -Dexec.args="2001 A"
mvn compile exec:java -Dexec.args="2002 B"   

3. Open Admin and User in the corresponding directories

mvn compile exec:java

Debug

To compile and execute with debug:

mvn clean compile exec:java -Ddebug
