passing -D argument with white spaces on UNIX

[wenmang]

Hi,

I try to pass a value to overwrite a value defined in the property
file by using following command on unix:
java -DMYENV="my value here" javaClass...

java cannot interpret it correctly, how can I get around it?

Thanks
WM

It should work just fine like that. The quotation marks aren't even
passed to Java, they're only used by the shell to keep the argument
together.

Exactly how does the received value differ from what you've typed on
the command line?

You should invoke Runtime.exec(String []) instead of Runtime.exec(String).
With the former, you are responsible for parsing the command into
arguments. With the later, Java parses the command into argument.

For example, use

exec(new String[] {"java", "-DMYENV=my value here", "javaClass"});

Have you tried single quotes as in java -DMYENV='my value here' javaClass...
