Embedding Java Code(URGENT)

Question

Hello,
I'm trying to do the following, I'm trying to embed Java code into my BPEL process, I have read the tutorial that explains how to embed a java code into BPEL(http://www.oracle.com/technology/products/ias/bpel/pdf/orabpel-Training-Segment10.pdf) but unfortunately the tutorial discusses only how to call the Entity Bean but doesnt mention where in folders(directory) should the bean itself be placed, where are the imports.
I'm going to start with a simple example, a class called Multiplier that has function square, Here is the code for the class:
//Java Multiplier class
public class Multiplier{
public Multiplier(){}
public int square(int x){
return x*x; }
this is code that will be placed in the EXEC(Java code snippet):
//Java Code Snippet goes here...
try{
Object input= getVariableData
("input","payload","/JavaCode");
String parser= input.toString();
int in= Integer.parseInt(parser);
Multiplier obj1= new Multiplier();
int result= obj1.square(in);
addAuditTrailEntry("The square of the input is:"+result);
catch(Exception en){
addAuditTrailEntry(en);
Where should the multiplier class be located(in which folder in the ecplise)or how will the BPEL refer to it ?
Shouldnt I import the Multiplier class in the EXEC(snippet) where should that line go?
Thanks in advance

After going through the Forum I saw I question similar to mine, and I found out there's an example similar to what I am trying to do at C:\orabpel\samples\references\JavaExec
I tried to make an example almost exactly like JavaExec and I edited my build.xml to be similar to build.xml of the example but I keep getting this error:
BUILD FAILED: C:\eclipse-SDK-3.0-win32\eclipse\workspace\Calc\build.xml:28: ORABPEL-00017
Java compilation failed.
Failed to compile file(s) "Calc.bpel".
Exception reported is: Calc.bpel:44: ';' expected.
Multiplier mult= new Multiplier();

Please verify that file Calc.bpel is valid java file or if all required libraries are included in your classpath.
classpath: C:\eclipse-SDK-3.0-win32\eclipse\startup.jar;C:\eclipse-SDK-3.0-win32\eclipse\startup.jar;C:\eclipse-SDK-3.0-win32\eclipse;c:\eclipse-SDK-3.0-win32\eclipse\plugins\bpelz_0.9.10\lib\orabpel-ant.jar;c:\eclipse-SDK-3.0-win32\eclipse\plugins\bpelz_0.9.10\lib\orabpel-boot.jar;c:\eclipse-SDK-3.0-win32\eclipse\plugins\bpelz_0.9.10\lib\orabpel-common.jar;c:\eclipse-SDK-3.0-win32\eclipse\plugins\bpelz_0.9.10\lib\orabpel-thirdparty.jar;c:\eclipse-SDK-3.0-win32\eclipse\plugins\bpelz_0.9.10\lib\orabpel.jar;C:\DOCUME~1\temp_ps\LOCALS~1\Temp\bpelc40446.tmp\BPEL-INF\classes
Here's the java code in the EXEC(snippet):
// Java code snippet goes here ...
com.otn.samples.javaexec.Multiplier
Multiplier mult= new Multiplier();
Object obj1= getVariableData("input","payload","/Calc");
String str= obj1.toString();
int in= Integer.parseInt(str);
int result= mult.square(in);
addAuditTrailEntry("The result is: "+result);
Finally here's the my build.xml:
<?xml version="1.0"?>
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
