JBuilder6 EJB with MS Access help me please ?

Hello...
I have some problem .........???
I starting learn about EJB.
i want to make new project about database.
jbuilder6 to create EJB.
database = MS.Access and use ODBC to connect.
I use Jbuilder to generate all of EJB (EJB module,EJB Entity Bean Moduler ,and TestClient)
No error when Complied.
but when write some code in main function(TestClient)
client.create(123,"aaa","bbb"); and then Rebuild again.
This time,HAVE ERROR = no have method !!!
1.what's wrong ???
2.Are MS.Access(ODBC) support with Jbuilder/EJB ??

After That.
I try to do it again.
>>In Test Client<<
public static void main(String[] args) {
BookTestClient1 client = new BookTestClient1();
client.create(3);
//(data type=String)
client.setTitle("JavaBean2");
client.setAuthor("xxx");
//(data type = double)
client.setPrice(58.54);
### Why Error 'only' in the last line And How I can do ???
