Update the L2J connector
Replace connector core 2.0.0 and verify the integration after an update
The current L2J connector core is 2.0.0. It targets Java 17 and is published
as portal-connector-core-2.0.0.jar with the required
minimal-json-0.9.5.jar dependency.
Update
Download the current JAR
Open Admin → Game Servers and download the connector core offered for this server.
Stop and replace
Stop the GameServer, remove the previous connector-core JAR, and add the new one. Keep exactly one connector-core version on the classpath.
Recompile
Compile ForgeportIntegration.java and the game server against the new JAR.
This catches public API changes before deployment.
Restart and verify
Start the GameServer, confirm the card reports core 2.0.0, run Connector
check, and perform one real item delivery on a test character.
The handshake field shown internally as adapterVersion is retained for
protocol compatibility. In Admin it is presented as the connector core version.
