How to compile a JavaBean?


I'm learning JavaBeans and it's application I'm creating my first ever Bean, I use an IDE called JCreator(free) which I have been using so far for the the compilation process of Servlets and I transfer the .class file to the local Apache server.

In my lecture notes it states that I need to store the JavaBeans I create in a package, which according to my understanding should reside inside the JDK version I use, am I right? The notes talk about the following command to line method for this

javac -d. newBean.java

I use a local folder in my E: drive to store all the Java files I create and compile them there, obviously I move the class files in to the classes folder in my WEB-INF in my Apache which is located in local C:


Solution

  • One way to solve the assignment requirements.

    Assuming a directory structure as follows:

    C:\projects\stackoverflow\3748425>dir /s
     Volume in drive C is WINVISTA
     Volume Serial Number is 3079-C372
    
     Directory of C:\projects\stackoverflow\3748425
    
    09/19/2010  07:55 PM              .
    09/19/2010  07:55 PM              ..
    09/19/2010  07:56 PM              beans
                   0 File(s)              0 bytes
    
     Directory of C:\projects\stackoverflow\3748425\beans
    
    09/19/2010  07:56 PM              .
    09/19/2010  07:56 PM              ..
    09/19/2010  07:58 PM               540 Bean1.class
    09/19/2010  07:57 PM               357 Bean1.java
                   2 File(s)            897 bytes
    
         Total Files Listed:
                   2 File(s)            897 bytes
                   5 Dir(s)  170,347,962,368 bytes free
    
    
    

    And a Java source code file...

    
    package beans;
    
    public class Bean1 implements java.io.Serializable {
    
      private String a;
      private String b;
    
      public Bean1(){}
    
      public void setA(String a){
        this.a = a;
      }
    
      public void setB(String b){
        this.b = b;
      }
    
      public String getA(){
        return this.a;
      }
    
      public String getB(){
        return this.b;
      }
    
    }
    

    You can compile it with this command:

    javac -d . beans\Bean1.java
