starting 2nd RCP from first [message #435421]

We developed 2 RCP applications which were exported as products.
Using the first RCP, we modify the startup ini file from the second RCP.
If we manually start the 2nd RCP, the changes in the ini file will then take
effect.
However, we would like to invoke this 2nd RCP from our first RCP.
Normally one would do this with:

sorry, my MS mail client decided to post this message before I was ready
typing.
Anyway, where was I, oh yeah, starting an external program in java.
one way of starting an external program:

new CmdExec("my2ndRCP.exe");

or

Process p = Runtime.getRuntime().exec("my2ndRCP.exe");
p.waitFor();

However, this is a bit nasty since we deploy our RCP for several platforms.
Is there a nice way of starting the 2nd RCP? We know the location of the 2nd
RCP
during runtime of the first RCP.

If not having a splash screen is not a problem, and if the startup ini
file you are referring to is config.ini or <eclipse>.ini then you can
run java.exe -jar startup.jar
Otherwise you would have to know the platform you are running and do the
ugly if case :-)

You mean something like,

if(myApplicationStartupCommand.indexOf(".exe")>-1){

run MS command

}else{

the rest

}

Interesting, but hey, if it works, we don't care ;-), thanks, we will test
it

OK we've found it:

Program.launch(String fileName);

Class Program in which the launch method is static.
Api documentation of this class can be found here:
