Anybody knows how to decompile IBM J9 jxe file(PQ MIB2 nav)? - Connected Car

Hello guys
I'm working on the Technisat PQ MIB2 system reverse engineering.
I want to remove the component protection.
Now I know the HMI program is written in Java, and compiled (packed) as jxe file.
jxe file is made by IBM J9 JDK tools jar2jxe.
But IBM J9 JDK is not open download
I searched all the internet and not found where to download IBM J9 JDK
Does anybody know where to download it? Or how to decompile the jxe file or the .classes file in jxe package?

Some progress?

built ffmpeg dlls for windows mobile are available

In the past, I get many helps from here.
I met lots of troubles while building ffmpeg for winCE. But I'm lucky to build them out finaly. I know some ones prefer to get the dlls directly rather than build it by themselves. So I upload them here: http://www.mediafire.com/?jc4w8mex9mw
Just feel free to get them if you need it.
ok, it may sound a silly question, but what app is suposed to take benefit of that ?
RTSP
Great job! Thanks
Did you build it with rtsp support? I can 't manage opening an rtsp stream: "File not found error"
rtsp.h files are present
In your begin method, in the name you preceed sample.avi with some strange char's what are they for?
Kind regards
Wim
I have also been trying to compile this for the ARM4 platform, would it be possible for you to build for this platform (ARM4i is only for WM5/6 and Im also developing for WM2003/CE.NET 4.2)
Thanks
sorry, rstp seems not supported defaultly.
the strange chars is diretory name. You could change them to "\\Storage Card\\sample.avi" or any others you like.

Hi,
Been trying to use your FFMPEG.DLL but I need the network capability of FFMPEG, could you recompile with --disable-network removed from your configure?
I have built FFMPEG myself but I keep getting a green screen on any video output, sound works okay. Did you get this? If I switch to your DLL I it works but I can only open local files.
To get libavformat to build I had to change a line in configure (amongst other things) to:
network_extralibs="-lws2"
from:
network_extralibs="-lws2_32"
Thanks!
Hy,
can anybody build ffmpeg with support stream video files from network?
Thanks a lot.
Greatz

Hy,
is anybody out there?
I think the original Youtube app uses ffmpeg - just go to youtube from your mobile, download the cab, install and you'll find ffmpeg.dll in /program files/youtube so you can try use this one...
Hy,
thanks for your answer. I tried this. But ffplay don't work with this dll well.
If have linked in the project below but i dosent work.
I tried to link avcodec, avutil and avformat ... But there is no coming out.
Since you know that it works now i will update this thread.
I have done it. You can see it here: http://forum.xda-developers.com/showthread.php?p=3819157#post3819157
ffmpeg WinCE is now Open Source!
For more informations look at our homepage http://www.ffmpeg-wince.org ...
See you!
Error :"Not a valid Pocket PC application"
hi
I have download the file from here: http://www.mediafire.com/?jc4w8mex9mw extract it and copy the bin, ffmpeg and Sdl directory to my project for wm 6.0
and successfully build the cab file. My cab file has exe and ffmpeg.dll, SDL.dll, swscale.dll files. After installation to my htc device 6.1 device whenever I try to run
file it gives me error message "Not a valid Pocket PC application".
Do have any idea why it is giving such error message.
Thank you.
Hello, I have also downloaded the files and am building testmain.exe using visual studio 2005. The exe is building and is running within the emulator. However on a windows mobile 6.1 classic PDA I am getting the error "testmain" is not a valid Pocket PC application.
Could anyone help me discover what the problem is?
I ran dumpbin /headers on the DLLs and the exe and saw that the header values are different and am wondering could this be causing the problems I have?

[Q] Question about apps_compressed.bin

Hi,
Is there any tool to compress apps compressed.bin and also for editing the file?
I know wave remaker can decompress and winhex is used for reading the bin, but are there any other tools
What exactly you expect to do?
Their are no Pictures to extract or to replace...
If you know what ELF, Binary, IDA and HEX Editor is and you have some ARM knowledge...
Then you have all incredients.
Only Compression Algo is missing...
Best Regards

Decompiling EXE

I am looking to decompile an exe written in C. The exe is the only file in the program and I'm looking to obtain the source so that I can recompile it with ARM support. The name of the application is SkiFree, and I'm only looking to do this so that I can run a version of it on Surface RT.

I don't know the original version, but would this be of any help?

Decompiling exe files is a minefield. I'd give up on that idea before even getting started. You're likely to get either something that doesn't rebuild or pure assembly language.

How to Repack appxbundle and xap files

Please tell me how can I repack an appx or xap app?
yes you can . by using makeappx.exe ( included in windows 10 sdk ) for re packaging appx or appxbundle files or repack any patched xap (it means copying installed xap from phone then) first making it a zip file then rename extension of the file to .xap then again deploy it windows phone 8.1 deployment tool to use it ...

Oh! So that's how it works!!
I have seen that some appx files have appx files inside, which is the reason they call appxbundle. Will it be possible to make appxbundle files by using makeappx.exe?
Like suppose I extracted Groove Music.appxbundle which contains appx of arm, x86 and x64. I modified each of them then packed each of them with makeappx.exe. Then what will I do to repack all of them to one appxbundle file? Should i use makeappx.exe on all of them?? Will that work??

yes you can repack appx packages into appxbundle by using this method
There are two ways
By using directory tree or by using mapping file ( i recommend you to use directory tree method once you have makeappx.exe running . you can repack your grove music (moded appx). make a folder (c:\APPX) paste all of your appx in that folder now use this command
MakeAppx bundle /d c:\APPX /p c:\gmusic.appxbundle use this for making any type of appxbundle this method is easy to understand and use
(you can change filepath.appxbundle to gmusic.appxbundle or whatever you what)
on windows 10 makeappx is used for packaging apps for ARM , X86 , AMD64 )
(for education only always support the developers by downloading apps from the app store )
