Global random generator usage (java/Linux)

[Benjamin Inden]

Hi,

I wonder how I can use the global random generator with a Bernoulli 
Distribution.

I am using Swarm 2.1.1 (SuSE RPM) with SuSE Linux 7.3 and java (Kaffe and Sun 
JDK 1.3.1 installed).

Here is what I tried:
BernoulliDistImpl yesOrNo;
yesOrNo = new BernoulliDistImpl();
yesOrNo.setGenerator(Globals.env.randomGenerator);
if(yesOrNo.getSampleWithProbability(synthesisProb)) {...

However, I get the following error at runtime:
*** event raised for error: InvalidArgument
*** function: _i_Object_s__forward__(), file: 
/usr/src/packages/BUILD/swarm-2.1.1/src/defobj/DefObject.m,
line: 626
unable to find Java selector `setGenerator:' in objc:`JavaProxy' 0x8712718 
java: 0x8e30bb0 hash: 21094
*** execution terminating due to error
/usr/src/packages/BUILD/swarm-2.1.1/src/defobj/Symbol.m:173 -[Error(c)

 /usr/lib/kaffe/libexec/Kaffe
'StartTuringCell'
-----------------------
When I comment out the "setGenerator" line, I get the following error:
*** event raised for error: InvalidArgument
*** function: _i_Object_s__forward__(), file: 
/usr/src/packages/BUILD/swarm-2.1.1/src/defobj/DefObject.m,

------------------------------
I also wonder how I can explicitly set the global random generator's initial 
seed to a certain value.
I want just one integer number to determine the whole run.

Any help is appreciated.
Thanks in advance,
