To get a copy of the bat file that Lorenz talks about, you can "Run" a panel from the G&B window and you should get a correctly configured Dot Bat file in your build folder like the following:
"C:\Program Files\Java\jdk1.8.0_74\bin\java.exe" -noverify -classpath ";;C:\StellaToolsV2.04\ModelLocal\Gen\Bld;C:\ProgramData\CA\Plex\6.1\ObJava\Lib\ObRun.jar" ObRun.ObPanel.ObLaunch LocalPNL.ST1cclF Path="C:\ProgramData\CA\Plex\6.1\ObJava"
REM // Provided the jar file contains all the required classes, you can use the jar file in this way:
REM // "c\java.exe" -noverify -classpath ";;C:\StellaToolsV2.04\ModelLocal\Gen\Bld\Local.jar;C:\ProgramData\CA\Plex\6.1\ObJava\Lib\ObRun.jar" ObRun.ObPanel.ObLaunch LocalPNL.ST1cclF Path="C:\ProgramData\CA\Plex\6.1\ObJava"
