Hi all, this post is in relation with this one viewtopic.php?f=81&t=29075 about change raise clan fee.

I want to ask you if there's some way to use the l2jserver.jar that I've build with "Ant build.." in my current version??
Because the full build folder have config files and much more. (If I replace all that config files everything in my server will be change) I mean, it exists some way to implement the new compiled l2j with modified code in my current version?? (I do not know if I've explained well, sorry =( )

(I tried replacing l2jserver.jar and server do not start, it crashes).

Thank you =)

if you dont have the source code of your jar file, you got 2 options:
1) Decompile it and rebuild from scratch
2) Intercept bytecode loader and inject your code directly in process virtual space

Iii.. dont think both options are so easy to make by his side

Actually .. I think we all didn't understand the question.

What I think the thread creator wants is to know a way to upgrade his server without having to upgrade everything else in the server-folder (that's a wild guess, of course).

If so, I think there is.

Replacing the l2jserver.jar is only part of the work.

After you've replaced that, you should copy and overwrite libraries inside the server/libs folder, following by a selective copying of datapack content into the appropriate folders.

That's why the devs on the L2 shard I am working on have created a separate project, which contains all of our scripts as well as classes, that we want to replace due to our own server modification. This way the core stays as clean from changes as possible while still being flexible.

Your best bet would be to find all of your changes (possibly using SVN and/or WinMerge), save them (as well as your configs) and then create a new server with the revision you want and manually merge the configs and files. I know it's cumbersome, but in your case (I suppose you don't have your own SVN and don't exactly know all of your changes) it's probably the best.

(sorry if I misunderstood you, but my guess is you've got exceptions after modifying a class - and thus you want to update everything - hence my poem )
