help you fix your problem In Java, import is entirely syntactic sugar. It does not add things to the classpath or load things into the runtime environment. It simply lets you write code without having to include the full classpath every time you mention the class. And when Java is compiled into Java bytecode, all classes are referenced by their full paths.

it fixes the issue You can't import a jar file just by changing the "import". But you can using the class loader. See How to load a jar file at runtime
code :
File file  = new File("C:\\dir\\file.jar");
URL url = file.toURL();  
ClassLoader classLoader = new URLClassLoader( new URL[]{ file.toURL() } );
Class cls = classLoader.loadClass("mypackage.myclass");

Hope this helps Try (change javax.persistence.sql-load-script-source path accordingly):
code :
<properties>
    <property name="hibernate.show_sql" value="true" />
    <property name="javax.persistence.schema-generation.database.action" value="drop-and-create" />
    <property name="javax.persistence.schema-generation.create-source" value="metadata-then-script"/>
    <property name="javax.persistence.sql-load-script-source" value="/import.sql"/>
</properties>

I wish this help you Import has nothing to do with CLASSPATH. It saves you keystrokes, allowing you to use short class names instead of full ones (e.g. ResultSet instead of java.sql.ResultSet) when you type your source code.
CLASSPATH matters at compile time, allowing the compiler to resolve static types, and at runtime when the class loader brings your byte code into the JVM at first reference.

lnramirez:Downloads lnramirez$ scala
Welcome to Scala version 2.11.7 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_65).
Type in expressions to have them evaluated.
Type :help for more information.

Does that help For what it's worth I was able to find a work around.
Drools has a library that tries to convert any excel decision table file into a DRL file. Using this library, I used my excel file's path and then essentially converted the DRL into a string to then add to the KIE session. It ended up looking something like this:
code :
import org.drools.decisiontable.SpreadsheetCompiler;

String rulesExcel = "C:\\my\\path\\file.xls";
InputStream is = null;
try {
  is= new FileInputStream(rulesExcel);
} catch (FileNotFoundException e) {
        e.printStackTrace();
}
SpreadsheetCompiler sc = new SpreadsheetCompiler();
String rules=sc.compile(is, InputType.XLS);
KieSession kieSession = new KieHelper().addContent(rules, ResourceType.DRL).build().newKieSession();
