World Wide Web (www) has achieved an important role in communication, information sharing and service delivery now-a-days. World Wide Web consists of millions of web sites and web based applications which are deployed and can be visited all over the world without the limitation of time and geographical boundaries. We discuss web drawing tool for creation of Logic gates ,UML diagrams simple draws. We discuss technical aspects like Mvc, Design Patterns, Demeter Law, Frameworks Persistence , ORM and Databases collecting the prerequisites for creating a web application and developing one. The application is made with Jsf Framework, Glassfish Server, PostgresSQL JavaScript and JPA. We use JPA as ORM tool for the mapping with the database tables and creating and storing Users. JavaScript is used for the stability and reabillty that has in web applications. Is a powerful programming language made for use in WEB applications. The combination of JavaScript makes the application response quick. The Java Persistence API, sometimes referred to as JPA, is a Java programming language framework managing relational data in applications using Java Platform, Standard Edition and Java Platform, Enterprise Edition. PostgresSQL is a the most advanced open source object-relational database server . It has a strong reputation for reliability, data integrity, and correctness. It runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, SGI IRIX, Mac OS X, Solaris, Tru64), and Windows. JavaServer Faces (JSF) is a Java specification for building component-based user interfaces for web applications. It was formalized as a standard through the Java Community Process and is part of the Java Platform, Enterprise Edition. GlassFish is an open-source application server project started by Sun Microsystems for the Java EE platform and now sponsored by Oracle Corporation.
