The implementation 

        STUTTGART UNIVERSITY OF APPLIED 

SCIENCES 

includes  both  data  and  functions.  In  addition,  programmers  can  create  relationships 

between one object and another. For example, objects can inherit characteristics from 

other objects. One simple example  is given as  following,  in this example, the server 

URL as variant was enveloped and transferred. 

      /** Set server s URL */ 

  public void setServerURL(Stringsurl){ 

          this.serverurl=url; 

        } 

        /** Return server s URL */ 

        public String getServerURL(){ 

                return serverurl; 

        }

Example of codes written in OOP method 

But  the  more  OOP  methods  the  developers  use,  the  more  classes  are  created,  that 

means  the  more  storage  and  memory  will  be  occupied  and  used.  Because  of  some 

limitation  as  mentioned  before,  J2ME  enters  in  a  dilemma  embarrassedly.  The 

developer  should  decide  when  OOP  could  or  had  better  to  be  used,  depending  on 

whether  the  variant  declaration  should  be  enveloped,  in  order  to  prevent  the  data 

overflowing and other aspects. 

In this application, the core process has four, 

1.

Records the data what the users create when they edit, add or delete the server list.   

2.

Parse  the  contents  of  XML  file  which  got  from  GetCapabilities  and  GetMap 

functions from WMS and transfer them to the other class.   

3.

Validate the result file from WMS after getMapRequest, justify the image format 

to choose which viewer will be loaded 

4.

Load the SVGT or PNG image from WMS and display on screen.
