I made a minor change to the stock demo to see it at a faster speed:

public long computeNextWaitTime() {
long millis;
/**do {
millis = (long) gaussian(mean, stddev);
} while (millis <= 0);
millis = 100;
return millis;

I copied the resulting classes to Lightstreamer/adapters/Demo/stocklist/classes
I removed the demos jar files from Lightstreamer/adapters/Demo/stocklist/lib
When I start lightstreamer it produces an error message :
Error while loading the Adapters: stocklist_demoadpaters.SockQuotesDataAdapter

I didn't think I needed to produce jar files since 'hello world' tutorial used only the class files and no jar files.

What steps do I need to take to use my modified files as the data adapter?
