Answer 1

Try this:

"C:\Program Files (x86)\Java\jdk1.8.0_73\bin\java" -cp %YOUR_CLASSPATH%;%YOUR_CLASSPATH_REPORTS%;%EXTRA_LIB% -Djava.library.path=./dll your.main.class

Before this line you need to set up your YOUR_CLASSPATH your YOUR_CLASSPATH_REPORTS and EXTRA_LIB with = and separating the concurrences with ";" (without the ""). For example:

SET EXTRA_LIB=.\\lib\\mysql-connector-java.jar;.\\lib\\anotherlibrary.jar; etc

Being the "lib" folder the one were you store your libraries, the route doesn't stricly needs to be the one shown on the example just put the one were you store your libraries (if you are using some ofc).

Also keep in mind that if you are going to use this bat in several machines they must have the same jdk installed and on the same route specified or you'll need to change it manually because the application wont launch.
