[Help] Editing .Class file


Question

Posted

from my l2jserver.jar i took a few .class files I wanted to edit/change. So I copied them and opened them with Dj Java decompiler. After making the changes I wanted it resaved the file as Filename.java (txt file) and Filename.JAD .

Im looking for some help to resave the files into .Class so i can reput them into the jar file. Unless im completely wrong how to edit and change files in my l2jserver.jar to make changes to my server.

You cant compile decompiled files from Dj Java decompiler ... it is only for if you want to look te class files without downloading source files . If You want to add your changes into core you must :

 

1. Download source files ( . java files )

2. Aplly your changes/patch

3. Compile it using Eclipse or Maven

 

Btw . Use search button ... read sticked topic's about compiling ...

Eclipse or Maven?o.O well he dont speak about l2jfree.. so its simple done with the ant build oO

    • ## [1.5.1] - 2026-01-30   ### 🐛 Bug Fixes - **Top Voters**: Top voters list now loads correctly for inactive servers (previously showed "Server not found"). - **View Counter**: Server info page view count now records correctly for inactive servers.   ### 🔄 Improvements - **My Servers – Hide/Active**: The hide/active toggle now works correctly and is only shown when the server is approved (active) by an admin. Owner hide/show is separate from admin status. Toggling no longer causes a full page refresh. - **Accessibility**: Form fields on the server info edit form, add server form, and related pages now have proper labels and IDs for screen readers and autofill.
    • LIVE VERIFICATION? SUMSUB? “IMPOSSIBLE”? ▪ Spoiler: it is possible — if you know who to work with. A client came in with a task to pass **live verification** on **WantToPay**, a Telegram virtual card service. On the platform side — **Sumsub**: liveness check, SMS, manual review. “Fast” and “by eye” simply don’t work here. › What was done: → analyzed the verification scenario and Sumsub requirements → built the correct flow: phone number, email, timing → **completed live verification remotely, without account handover** → handled SMS and confirmation codes → brought the process to final approval ▪ Result: → verification passed → access granted → no flags or repeat requests ▪ Live verification is not luck. It’s scenario-based preparation — not hope. › TG: @mustang_service ( https:// t.me/ mustang_service ) › Channel: Mustang Service ( https:// t.me/ +6RAKokIn5ItmYjEx ) *All data is published with the client’s consent.* #verification #sumsub #livecheck #kyc #case
    • IMPORTANT INFO: In a few days, I will switch to completely new code, written from scratch with a new download system, patch building and management system. The Updater will become true 2026 code with "foolproof systems". I'm going to create a Discord server for customers to request new ideas and features. FIRST CUSTOMERS ARE ALREADY USING THE NEW UPDATER ON LIVE SERVERS! Watch this topic for upcoming info because the new updater is around the corner! Yes, you can still use self-update on the previous updater! No, the new updater won't be compatible with the old patch system! A new build is required, but players who already have game files won't have to download the entire patch again! New templates and updates to existing templates are coming soon! Sneak peek:
