Abstract Mobile proxy server implementation is a mobile solution for registering complaints online for computerized customer care and servicing unit. New approach is used for this process to minimize the workload of database server. Here Java RMI concept was used to locate the remote server for particular customer ID authentication and registers complaints to the remote server corresponding to location of the customer registered the complaint.

Hardware Requirements Operating System: Windows 2000 and above Pentium III or IV 128 MB RAM Mobile phone with GPRS Connected with local area network.

Software Requirements Web Server Apache Tomcat Server 5.0 Browser Internet Explorer 4.0 Tools J2ME Wireless Tool Kit Server side scripting JSP, Java Servlets Database MS Access Language J2EE, J2ME
