Redirect System.out, System.err to a file or pipe

By default, stdout redirect is not enabled.

  • System.out and System.err can be redirected separately.
  • Stdout, stderr can be redirected to a disk file or system device such as PRN, NUL, /dev/null etc.
  • Stdout, stderr can be redirected to a pipe, though which the output will be stdin of another program.

Show a splash screen when program is starting up

Show a splash screen even run with JRE earlier than 1.5.

  • Automatically close when first window appears.

Hello,

Is it possible to run Jar2exe on Linux instead of Windows?

I have the following command that is runnng on windows console, we are passing *.j2e file that contains required information to build binary (saved project file). What I need, similar command to be run on linux shell instead of Window, is that supported?

j2ewiz /make myproject_lnx64.j2e

Best Regards,

Ayyoub

It will be supported in future release

Submitted by Sswater Shi on

Yes it is possible. In future release, Jar2Exe itself will be able to run on Linux and Mac. But now there is no exact schedule.

Now, you can use wine

Submitted by Sswater Shi on

Jar2Exe itself runs on Windows right now. You can use wine to start Jar2Exe command line mode, for example, in a script.sh :

wine /usr/local/bin/j2ewiz.exe \
    -o $TARGET \
    -m "$2" \
    -jar "(empty-jar)" \
    -encrypt \
    -keepflat "$FLATJAR" \
    $EMBED \
    -amd64 \
    -platform linux

Is the binary file created by linux system working properly on HP AIX7.1 server environment?

If you are on an HP AIX7.1 server, technical support is required.

Please confirm.

Thank you.

Add Pre and Post Command Line support feature

Submitted by Nasser (not verified) on

Hello Mate,

Your software is doing a really great job! However, It would be brillant if you could had support for pre and post execution command line.

For example, depending of the platform choosen such Window, Mac or Linux, I should be able to execute cmd line before and after my internal jar start (like your splash screen) if I use windows, Same for mac and linux using some script before the jar start.

I just tell, because I deal with complexe stuff, and it would be nice to have this kind of feature.

All the Best
