how to write code for displaying the current time through XHTML page

[pavan.pavankkotturi.kumar.gmail.com]

Hii, Everybody
 
         please any one can give suggestions on displaying the current time by using XHTML page.

Is there an example on seam folder regarding this one.

Any suggestion appreciable.
Thanking You in advance.

Try could try this for example:

• components.xml

<component name="now" scope="event" auto-create="true" class="java.util.Date" />

• using @Factory as alternative to components.xml

@Factory(scope=ScopeType.EVENT, autoCreate=true)
public Date getNow() {
    return new Date();
}

• xhtml

<h:outputText value="#{now}">
    <f:convertDateTime pattern="yyyy-MM-dd HH:mm:ss z" />
</h:outputText>

Hope that helps!

Hai ,
         I am developing the project on PROJECT MANAGEMENT by using seam frame work, on that one what I want is, I wish to enter task starting time and ending time.

         While clicking on those corresponding text boxes it'll accept the current time.

This one really I want.This is urgent to me.

Thanks once again.

OK, I think I know what you want to achieve. Here is simple example (project generated by JBoss Tools) which should help you.

Task Entity

@Entity
public class Task implements Serializable {
    private static final long serialVersionUID = 1L;
     
    private Long id;
    private Integer version;
    private String name;
    private Date startTime;
    private Date endTime;
     
    @Id
    @GeneratedValue
    public Long getId() {
        return id;
    }
// getters and setters

TaskHome

The interesting parts here are the methods startTask and endTask which set the start and end time.

@Name("taskHome")
public class TaskHome extends EntityHome<Task> {
    private static final long serialVersionUID = 1L;
     
    @RequestParameter
    Long taskId;

    @Override
    public Object getId() {
        if (taskId == null) {
         return super.getId();
     } else {
         return taskId;
     }
    }

    @Override
    @Begin
    public void create() {
     super.create();
    }

    public void startTask() {
     this.instance.setStartTime(new Date());
    }
     
    public void endTask() {
        this.instance.setEndTime(new Date());
    }
}

task.xhtml

Look at the a4j:commandButtons startTask and startTask.

<h:form id="taskForm">
    <a4j:outputPanel ajaxRendered="true">
        <rich:panel>
            <f:facet name="header">task</f:facet>
     
            <s:decorate id="nameField" template="layout/edit.xhtml">
                <ui:define name="label">Name</ui:define>
                <h:inputText id="name" required="true"
                    value="#{taskHome.instance.name}"/>
            </s:decorate>
                 
            <s:decorate id="startTimeField" template="layout/edit.xhtml">
                <ui:define name="label">Start Time</ui:define>
                    <h:outputText id="startTime" value="#{taskHome.instance.startTime}">
                        <f:convertDateTime pattern="yyyy-MM-dd HH:mm:ss" />
                    </h:outputText>
            </s:decorate>
                 
            <s:decorate id="endTimeField" template="layout/edit.xhtml">
                <ui:define name="label">End Time</ui:define>
                <h:outputText id="endTime" value="#{taskHome.instance.endTime}">
                    <f:convertDateTime pattern="yyyy-MM-dd HH:mm:ss" /> 
                </h:outputText>
            </s:decorate>
                 
            <div style="clear:both"/>
        </rich:panel>
     
        <div class="actionButtons">
            <a4j:commandButton id="startTask" 
                value="Start Task"
                action="#{taskHome.startTask}"
                disabled="#{not empty taskHome.instance.startTime}" />
            <a4j:commandButton id="endTask" 
                value="End Task"
                action="#{taskHome.endTask}"
                disabled="#{empty taskHome.instance.startTime or not empty taskHome.instance.endTime}" />
                  
        <h:commandButton id="save"
                value="Save"
             action="#{taskHome.persist}"
             rendered="#{not taskHome.managed}"
             disabled="#{empty taskHome.instance.endTime}"/>
        <h:commandButton id="update"
             value="Save"
             action="#{taskHome.update}"
             rendered="#{taskHome.managed}"/>
        <h:commandButton id="delete"
             value="Delete"
             action="#{taskHome.remove}"
             immediate="true"
             rendered="#{taskHome.managed}"/>
        <s:button propagation="end"
             id="cancel"
             value="Cancel"
             view="/taskList.xhtml"/>
        </div>
    </a4j:outputPanel>
</h:form>
