  27. JDBC Connections Import JDBC Packages Register JDBC Driver import java.sql.* ; // for standard JDBC programs DB URL Formation import java.math.* ; // for BigDecimal and BigInteger support Create connection object Close connection JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  28. JDBC Connections Import JDBC Packages Approach I - Class.forName() Register JDBC Driver try { Class.forName("oracle.jdbc.driver.OracleDriver"); } catch(ClassNotFoundException ex) { System.out.println("Error: unable to load driver class!"); System.exit(1); } DB URL Formation Create connection object Close connection JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  29. JDBC Connections Import JDBC Packages Approach II - DriverManager.registerDriver() Register JDBC Driver try { Driver myDriver = new oracle.jdbc.driver.OracleDriver(); DriverManager.registerDriver( myDriver ); } catch(ClassNotFoundException ex) { System.out.println("Error: unable to load driver class!"); System.exit(1); } DB URL Formation Create connection object Close connection JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  30. JDBC Connections Import JDBC Packages getConnection(String url) getConnection(String url, Properties prop) Register JDBC Driver getConnection(String url, String user, String password) RDBMS MYSQL JDBC Driver Name URL DB URL Formation jdbc:mysql://hostname/ databaseName jdbc:sybase:Tds:hostname: port Number/databaseName com.mysql.jdbc.Driver Sybase com.Sybase.jdbc.SybDriver Create connection object DB2 COM.ibm.db2.jdbc.net.DB2Driverjdbc:db2:hostname:port Number/databaseName Oracle jdbc:oracle:thin:@hostname:port Number:databaseName Close connection oracle.jdbc.driver.OracleDriver JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  31. JDBC Connections Import JDBC Packages Register JDBC Driver Using a Database URL with a username and password Using Only a Database URL DB URL Formation Using a Database URL and a Properties Object Create connection object Close connection JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  32. JDBC Connections Import JDBC Packages Register JDBC Driver To ensure that a connection is closed, you could provide a 'finally' block in your code DB URL Formation conn.close(); Create connection object Close connection JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  33. JDBC Statements Statement Callable Statement Prepared Statement JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  34. DEMO

  35. Introduction to Servlets

  36. What are Servlets? Server Client Request Response is sent to client Response is generated at runtime JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  37. What are Servlets? Robust & Scalable Creates Web Application Deployed to create Web Page Provides Interfaces & Classes Responds to any incoming requests Must be implemented to create Servlet JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  38. Servlet Life Cycle Loading & Instantiation Start init() Initialized End of Request thread service() Handling Request destroy() End Stop JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  39. Steps to create a simple servlet Create and compile servlet source code Copy servlet class file & add mappings to web.xml file Start Apache Tomcat Start Web Browser & Request the Servlet JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  40. Session Tracking in Servlets Session tracking is a way to maintain state(data) of an user. 3. Second new request 1. Request(new) 2. Response Client Server JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  41. Hidden form field Cookies Http session URL rewriting JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  42. Cookies in Servlet It is a small piece of information that is persisted between the multiple client requests. 2. Request + Cookies 1. Request 3. Response + Cookies JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  43. Useful Methods of Cookie Class Sets the maximum age of the cookies in seconds public void setMaxAge(int expiry) Returns the name of the cookie. Name cannot be changed after creation public String getName() Returns the value of the cookie public String getValue() Changes the name of the cookie public void setName(String name) Changes the value of the cookie public void setValue(String value) JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  44. Creating & Deleting a Cookie 1.Cookie ck=new Cookie("user",“Edureka");//creating cookie object Creation 2.response.addCookie(ck);//adding cookie in the response 1.Cookie ck=new Cookie("user","");//deleting value of cookie 2.ck.setMaxAge(0);//changing the maximum age to 0 seconds 3.response.addCookie(ck);//adding cookie in the response Deletion JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  45. Pros & Cons of Cookies Useful & Easy Technique to maintain the state Maintained at client side Wont work if cookie is disabled form browser Only textual information can be set in cookie object JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  46. Introduction to jsp

  47. What is JSP? It is used to create web application just like Servlet technology. Also called as extension of servlet Portable Fast Development Powerful Tracking User Flexible Easy to maintain JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  48. Advantages of JSP over Servlets JSP ▪ Extension to Servlet ▪ It is not a extension of JSP ▪ Easy to maintain ▪ Bit complicated ▪ No need to recompile and redeploy ▪ Code needs to be recompiled ▪ Less code than servlet ▪ More code comparatively Servlets Operation JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  49. Life Cycle of JSP Buffer JSP (dynamic content) JSP Translator Servlet Object Servlet (.java File) JRE Compiler Class file JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training

  50. JSP Scripting Elements scriptlet <% java source code %> expression <%= statement %> declaration <%! field or method declaration %> JAVA CERTIFICATION TRAINING www.edureka.co/java-j2ee-soa-training
