javabeans

I am trying to iterate through a 2d array of integers and represent them in a grid using the <table> tag. The catch is that I am not allowed to use any java-script. I know it is something to the effect of the below code, but more complicated. And boardArray returns a 2d integer array. So how would I extract the value at each cell? There is a predetermined size of the array as well. <c:forEach var="array" items="${bean.boardArray}"> <tr> <td>${print out contents of a row}</td> </tr> </c:forEach> You can't do that with plain HTML. You've mentioned HTML in the original question title, but since

As mentioned below I have made changes to the code which looks like following example, but it doesn't show firstname and lastname in JSP: Servlet code: //.... HttpSession session = request.getSession(); Person person = (Person) session.getAttribute("person"); if (person == null) { person = new Person(); } person.setNewId(newId); person.setFirstName(firstName); person.setLastName(lastName); session.setAttribute("person", person); RequestDispatcher rd = request.getRequestDispatcher("jsp Address"); rd.forward(request, response); Person Bean code: private int newId; private String firstName;

I have a question regarding declaration of classes in applicationContext.xml In applicationContext.xml do we need to specify all the classes from the application? E.g. In my small web application I have a Entity class, Service class and DAO class. So currently it is defined as <!-- Beans Declaration --> <bean id="Employees" class="net.test.model.Employees" /> <!-- User Service Declaration --> <bean id=" EmployeeService" class="net.test.employees.service.EmployeeService"> <property name="employeesDAO" ref="EmployeeDAOImpl" /> </bean> <!-- User DAO Declaration --> <bean id="EmployeeDAO" class=

@BeanProperty generates simple get / set methods. Is there a way to automatically generate such methods with support for firing property change events (e.g. I want to use it with JFace Databinding?) I've had the same question, and have been keeping a close eye out for possible answers. I think I've just stumbled across one (although I haven't tried it yet). Scala 2.9 has a feature for handling dynamic calls (meant for integration with dynamic languages, I suspect). Essentially, calls to methods which don't exist are routed to a method called applyDynamic. An implementation of that method could

I have spring web application. I have defined the controller bean which takes the bean of service as property. Also service bean takes the Dao. Dao is tested and working fine. Now the problem with service. Actually i'd make sure about the setters there ! so what is the problem ? Controller Bean : <bean id="listTypeController" class="me.web.servlet.controller.ListTypeController"> <property name="typeService" ref="typeService" /> </bean> Service Bean : <bean id="typeService"class="me.general.service.impl.TypeServiceImpl"> <property name="genericDao" ref="genericDao" /> <property name="typeDao"

Defining data members in a class that can be publicly accessed/modified var _foo: Int = _ def foo_(foo: Int) = _foo = foo // setter function def foo = _foo // getter function Is it a good practice to convert this using annotation @BeanProperty ? import scala.reflect.BeanProperty @BeanProperty var foo: Int = _ and when to use this annotation and when not to? There's some redundancy in your first example, since defining a var already results in the generation of getters and setters. For example, if we compile this class: class Foo { var foo: Int = _ } Then javap -private Foo shows the following:

I would like to understand whether I should clean prototype-beans from memory manually by myself. In the Spring documentation you can see: "The client code must clean up prototype-scoped objects and release expensive resources that the prototype bean(s) are holding." So from this it seems that you should clean prototype-beans by yourself. However. I'm using VisualVM memory profiler . I have created a number of prototype-beans. You can see 51 instances of them. Then you can see the situation when the garbage collector clean the memory - all prototype-beans were cleared . So can anyone clarify

I have a JSP page with checkboxes inside an HTML form as below Now while editing user Skill I want to take the comma separated values from the table and populate the checkboxes in JSP. The following code brings the CSV Skills from the database table. List<UserDetails> Skills = new ArrayList<UserDetails>(); pstmt = (PreparedStatement) conn.prepareStatement(strSQL); rs = pstmt.executeQuery(); String strSkills = rs.getString("Skills"); List<String> items = Arrays.asList(strSkills.split("\\s*,\\s*")); objUserDetails.setSkills(items.toArray(new String[0])); Skills.add(objUserDetails); return Skills

Why does Spring automatically choose the superclass types during autowiring? For instance, if I have @Component public class Foo {} @Component public class Bar extends Foo {} and someone autowires @Autowired private Foo foo; How come Spring always chooses the supertype Foo ? Shouldn't this be an " ambiguous " mapping (and cause Spring to throw an error)? Don't you technically have two Foo candidates? (e.g., Bar gets automatically picked when @Component is removed from Foo...) That might be because the autowiring is done by name, not type. If I setup my bean using xml like this: <bean id="foo1"
