Default Recover old links

I have old version of jdownloader, version which buged itself when trying to update.

*Where I can read JD version (UEdit,Whex literate)
*Backup files are in backup directory; links.linkbackup and database.zip
*Old backup files are renamed with rule database_1237662824000.zip
*Current version is 0.9.421
*Two versions are on different lan connected PC
*Is there some REG data to reveal version?
*Is there portable version of JD, orginaly portable, not Thinstalled, or citrix or nill modified..?

How to revive old links, becouse i used JD as link collector and download manager till fatal error.

If it is possible, is there way to start old version JD on new java version (maybe that was problem)

Cool

Many questions..I'll try to answer those that I understand.

The jD version can be checked with ? -> About jDownloader (don't use Ctrl+F1 because that gives the Change Log)

jD is portable, you can just move your jD folder to any folder, disk, USB stick or PC you want.

For updating issue, exit jD and start jdupdate.jar in your jD folder.

For making a backup, use File -> Save -> Backup. jD stores its backups in the backup directory of the jD folder. The database.zip is the current backup. The database_NNNNNNNNNNNNN.zip files are older backups. When you extract a backup file in the config folder you get the settings and links of the backup.
Please, exit jD before you do the extraction. The extraction will overwrite the current files in the config directory. If you want to keep the current config files, please make a backup of those files first.

Default Explanation...

Maybe I was not clear...

*I can not start old version of JD to know what version it is.
*I have old version files in JD directories and subdirectories.
*It can be started , as it is portable, but i did not check reg write or relaying of JD on that data in reg , or my documents subdir...so i am not sure of portability.
*old and current version of JD seems to have different backup definition...

you can download new version, let it update and then copy the config folder of your old jd (if its not too old) to new jd...i think (but cant say for sure) that update from 0.6(not sure)/0.7/0.8 to 0.9 is possible.

If you cannot start an older version it might be because it's already started but not showing its GUI because of a blockage of your firewall or anti-virus software. Please look in your Task Manager for java(w).exe process and kill it if you're sure it's jD

You can always try to migrate slowly to newer versions if the old backup formats are no longer compatible. This might be a slow process though. Here are some older versions :- hXXp://www.mediafire.com/?sharekey=440d0e65dc3b9b1019747bd91027d4ddaed3c187eb65c611

disabling web/http scanning will not get you in more danger, because all files are still get scanned when they are on your disk. only difference is that they are scanned when on disk and not while downloading (which causes speeddrops, issues and more space needed for extra check)

First of all, you should now find out what caused jD's (i.e. Java's) crash.

It might be a virus program. Allow java.exe and javaw.exe in your firewall and virus software. Also disable html/web scanner in your virus software. Also move your jD folder to the c:\jdownloader folder and remove all write protections if you're running Vista/W7.

If you've solved that problem I would recommend you to make regular backups of your links. You'll find jD's backup functions in the File -> Save menu.

Besides that I keep my links, sources, additional info and passwords in a separate text file. I never lost anything, because I version that file and it's included in my daily, incremental backup of my disks.

I lost mi download list when I installed new version of JRE. There are 76 backups in my backup folder. In JDownloader I'm missing a tool to recover links from a backup zip.
I'm stuck. :-(

Exit jD and extract your most recent backup file over jD's config folder.

If you upgraded to java 1.6.0_26 then you need to read "Attention very important when upgrading to Java 1.6.0_26".

Are you joking?
I simply can't imagine an application that would delete data after 3rd party component update.
And I can't presume that JRE update will delete data in my computer. That's TRAGIC!!! There must be a way how to import download list from a backup ZIP file.

It's the first time I see this happen.

Quote:
The problem was caused by an internal change in the 1.6.26 update which was made for security reasons (apparently there was some hole in the logic used to handle the ImageIcon class and the manner in which it was changed made it incompatible with versions of the user and system icon archives created with earlier versions of Java).
You see to what an ImageIcon class security hole can lead.

You've only one way to go and that's downgrading. Remove all your java and install the 32 bits version of JRE 1.6 update 21. See "**External links are only visible to Support Staff**.

I'm affraid there's something wrong with JDownloader. I have restored my system to June 15th but I'm still missing my download list. JRE on my PC is 6 Update 24.

Downgrade to Java 6 21 did it! Thank you very much for your help.

They (java developers) made some changes to the newest JRE and then application created with older versions of JRE are being incompatible?
So we can't upgrade to newest 6u26 JRE (we can't install security patches with this release) because jD will loose download list.
Very nice Oracle...

I don't know, but maybe jD developers should report it to Oracle as BIG bug in 6u26 and there are any other possibilities (when you have thousands links - finishing them and then upgrade is no real, quick solution) to resolve this problem.
Or maybe jD developers can create somekind of export/import (to XML? of course there would be still problems with DLC links) to help migrate links before and after java update?

I thought the problem only exists for the database files, not .dlc nor .jdc files.

If people first completely download their downloading links, remove the downloaded links and use the Save Linklist function, they'll only lose their configuration settings.

remi: by DLC I mean links created via DLC container and already in database.

Loosing config settings is not such a big problem - it can be really quick restored (premium setting, jD settings etc).
The new (future) jD already keeps it's configuration in separate (json or encrypted ejs) files, so I think it's immune for such "improvements" in java core.
The problem are the links stored in database - when their number is small - the solution given by jD developers is ok, but when you're storing many links for future downloads or for checking if you already downloaded some files - there is a real problem.
So the best solution would be not simple database backup (links + config) but rather export/import feature (maybe only links - some work is already done because we can export links to XML using jD's web interface).
This would help if Oracle again messes sth with their java updates (I wonder what would happen if they make something similar with their databases: database created with older version missing records after updating database core... - the clients would eat them alive!

I wrote that the File -> Save Linklist function might do just what you want. Use that function before you upgrade, do the JRE upgrade and then load the .jdc container.

The config settings aren't that important for most people (like me), because they probably use the default settings, but some people pay for downloading or use the JD Unrar extension and have many passwords. The .rar passwords can be copied to a text file, but the accounts can't. Also reconnect scripts can be copied.

Orakel have always had database export/import utilities for their database systems.

Note that I would also prefer XML export/import because then I could do many more things with my links, but it doesn't exist in the stable version.
