第一个设计模式非常简单。一个公司和雇员的entity bean和
下面给出的entity bean的代码片断是类似的。它们是由jbuilder4的
entitybean模版生成的。所有的字段都声明为public的cmp字段。
code snippet for company entity bean
public class companybean implements entitybean {
entitycontext entitycontext;
public integer comid; //the primary key
public string comname; //the company name
public string comdescription //basic description
public timestamp mutationdate //explained later
public integer ejbcreate(<params>) throws
createexception {
return null;
}
//various get() and set() for every column/field
// which are exposed in the remote interface as well
code snippet for employee entity bean
public class employeebean implements entitybean {
entitycontext entitycontext;
public integer empid; //the primary key
public integer comid; //the company foreign key
public string empfirstname; //the employee firstname
public string emplastname // the employee lastname
public timestamp mutationdate //explained later
public integer ejbcreate(<params>) throws
createexception {
return null;
}
