JAR executable and parameters

in Integration and Hardware • 1 month ago

Hi.
I use Processing 1.5.1 in Windows to produce some PNG images and then call exit() as last command in setup().
The sketch is then compiled as applet and executed from command line with
> java -jar sketch_name.jar
This works.

What if I want to read some command line arguments to specify PNG's parameters (such as filename, size, etc) inside the sketch? I saw that args[] is always long 1 and contains the jar filename. Extra arguments are lost...

I would like to be able to call the applet with
> java -jar sketch_name.jar param1=value1 param2=value2

I tried -Dproperty=value but system property values don't look like working with this syntax in Processing.
Any hint?

Thank you in advance
Alex

H:\PhiLhoSoft\Processing\Bah\application.windows32\lib
> java -cp core.jar;Bah.jar Bah foo bar
user.dir: H:\PhiLhoSoft\Processing\Bah\application.windows32\lib
sketchPath: H:\PhiLhoSoft\Processing\Bah\application.windows32\lib
[0] "foo"
[1] "bar"

With sketch:

Copy code

void setup()
{
println("user.dir: " + System.getProperty("user.dir"));
println("sketchPath: " + sketchPath);
println(args);
exit();
}

Hi PhiLho.
That's definitely strange: I don't get your result.
I tried using Processing 1.5.1 and 2.0b7, both exporting as applet and application.windows.
In all 4 cases I can only read a single parameter and this is the sketch name. No arguments.
Executed in IDE I get of course more parameters such as --external, --display=1, etc.
I executed it in Windows 7 and Windows 8. Same result.

By the way: I am using Command Prompt and set manually Java path as c:\Processing1.5.1 [2.0b7]\java\bin.

Copy code

C:\Users\alex\Desktop\sketch_sep19a\application.windows\lib>java -cp core.jar;sketch_sep19a.jar sketch_sep19a abc def
user.dir: C:\Users\alex\Desktop\sketch_sep19a\application.windows\lib
sketchPath: C:\Users\alex\Desktop\sketch_sep19a\application.windows\lib
[0] "sketch_sep19a"

Looks like I'm missing something important here.
Thank you anyway for your help.
Alex

Got this result with Processing 2.0.0, on Windows 7, with Java 7.
