Try a test bean


Test bean
---------

package demo;

public class Test {
public String cancel() {
System.out.println("cancel() called");
return "startPage";
}

public String save() {
System.out.println("save() called");
return "startPage";
}

private String field1;
private String field2;

public String getField1() {
field1 = readField1FromDatabase(); // read field1 from database
System.out.println("getField1() called; return " + field1);
return field1;
}
private String readField1FromDatabase() {
return "Ponnazhagan";
}

public void setField1(String field1) {
System.out.println("setField1() called with " + field1);
this.field1 = field1;
}
public String getField2() {
field2 = readField2FromDatabase(); // read field2 from database
System.out.println("getField2() called; return " + field2);
return field2;
}
private String readField2FromDatabase() {
return "Sudhakar";
}

public void setField2(String field2) {
System.out.println("setField2() called with " + field2);
this.field2 = field2;
}
}

Test.jsp
