Javaone: Evolution of JSF-Ajax has arrived

 

Recently, I have been paying close attention to Java One. The coming of ejb3 is naturally a top priority, but it is not necessary to worry about its applications. Today I saw a report on JSF, which is worth mentioning.
Let's take a look at JSF's latest Ajax-based API, which has simply encapsulated ajax to the end:
1. Automatically fill in the table column

Code:
<UI: AutoComplete size = "40" maxlength = "100" id = "cityfield" completionmethod = "# applicationbean. completecity} "value =" # {sessionbean. city} "required =" true "ondisplay =" function (item) {return extractcity (item);} "onchoose =" function (item) {return choosecity (item );} "/>

2. Google Map

Code:
 <ui:mapViewer id="mapViewerx" center="#{MapBean.mapPoint}" info="#MapBean.mapMarker}"
     markers="#{MapBean.locations}" style="height: 500px; width: 700px"/>

3. input box for selecting values

4. Document Editor

5. Yahoo-like scoring buttons

Code:
<UI: rating id = "rating" maxgrade = "5" comment denotinterested = "true" comment declear = "true"
Hovertexts = "# {ratingbean. ratingtext}" notinterestedhovertext = "not interested"
Clearhovertext = "Clear rating" grade = "# {ratingbean. Grade}"/>

6. Calendar

7. Form Verification

Code:
<UI: ajaxvalidator messageid = "input1" eventhook = "onkeypress">
<H: inputtext>
<F: validatelength minimum = "3"/>
</H: inputtext>
</UI: ajaxvalidator>

8. upload tool

Code:
<ui:FileUploadTag id="TestFileuploadForm0" enctype="multipart/form-data"
      retFunction="testRetFunction" retMimeType="text/xml" postProcessingMethod="#{FileUploadProcessing.postProcessingMethod}"
        progressBarDivId="progress" progressBarSubmitId="submit1x" progressBarSize="40">
            <input type="file" size="40" name="fileToUpload0" id="fileToUpload0Id"/><br>
            <input type="file" size="40" name="fileToUpload1" id="fileToUpload1Id"/><br>
            <input type="file" size="40" name="fileToUpload2" id="fileToUpload2Id"/><br>
            <input type="submit" name="submit1x" value="Submit"/>
      <div id="progress"></div><br/>
</ui:FileUploadTag>

Currently, this Ajax component is still in blueprint and cannot be directly downloaded and used. You can install it for trial using sun's Java creator. I think the idea of JSF is from. net, so there is no good ide support to write the program, it is very difficult.
