Here is my command line options I use to run JBidwatcher-2.99pre5 for Windows.

Hope it is useful for some one.

Just add thise line below to a batch file and save (example jbidwatcher.bat)
There are two important things you should do.
1 Make sure the path for javaw.exe and JBidwatcher are correct
2 -Duser.home=D:\dat\jbidw (change the path and folder name where you want to put Jbidwatcher home directory where it keeps all data.

"C:\pro\jre8x64\bin\javaw.exe" -Xmx256m -Duser.home=D:\dat\jbidw \
-classpath "C:\pro\JBidwatcher\JBidwatcher-2.99pre5.exe;C:\pro\JBidwatcher\lib\annotations.jar; \
