5- add content presenter to your page where the content is “content under folder”& template the one created in the step above.

Call a bean method after ajax call

Many requirements asks to call external service using ajax or do some javascript like using js calendars and on user click send the response to the bean to save it in database or to do some business validation.

The way to do that is using serverListener & clientListener .

The serverListener tag is a declarative way to register a server-side listener that should be executed when a custom client event is fired.

while The clientListener tag is a declarative way to register a client-side listener script to be executed when a specific event type is fired.

I have created a small demo application that calls ajax call & jquery to get location & ip and then we will send it to back bean which will be printed in the console.

Lets see the steps

1.create a jspx page and add a button like this

 <af:panelGroupLayout id="pgl1" layout="vertical">
<af:commandButton text="Get My Location" id="cb1">
<af:clientListener type="action" method="callAjaxAndNotifyServer"/>
<af:serverListener type="servListener"
method="#{backingBeanScope.DemoBB.getAjaxCallbackValue}"/>
</af:commandButton>
</af:panelGroupLayout>

2. add af:resource with the code below

 var actionbtn;
 var response_Json
 function callAjaxAndNotifyServer(actionEvent) {
 actionEvent.cancel();
 actionbtn = actionEvent.getSource();//
 alert(actionbtn);
 $.ajax( {
 url : "http://ip-api.com/json/", data : '', type : "GET", error : function (XMLHttpRequest, textStatus, errorThrown) {

 alert('error');
 ajaxError(XMLHttpRequest, textStatus, errorThrown);
 },
 success : function (data) {

 response_Json = JSON.stringify(data);

 console.log(response_Json);
 AdfCustomEvent.queue(actionEvent.getSource(), "servListener",
 {
 fvalue : response_Json
 },true);
 return false;
 },
 error : function (xhr, status, err) {

 console.log('error');
 var err = eval("(" + xhr.responseText + ")");
 alert('' + err.Message);
 console.log('Error in Ajax
 call:' + err.Message);
 }
 });
 }

where
actionEvent.cancel(); is needed if you are using commandbutton without partialsubmit=”true”
and
AdfCustomEvent.queue(actionEvent.getSource(), “servListener”,
{
fvalue : response_Json
},true);
return false;
registers the custom event and set parameter “fvalue” with the json string value

3.create a bean for example backbean demoBB with method name getAjaxCallbackValue 

that you already referenced in your serverListner in step 1 & add the code to this method as follows to print the value

public void getAjaxCallbackValue(ClientEvent clientEvent) {
System.out.println("-----------------------------------------");
System.out.println(clientEvent.getParameters().get("fvalue"));
System.out.println("-----------------------------------------");
}

 

 

Update web.xml in webcenter portal

Sometimes you need to update the web.xml for webcenter portal if you want to disable compression or add servelets or change the session timeout.

As you know the webcenter potal (AKA Spaces before) is already deployed application .

In order to update the web.xml you need to create extension shared library and add web.xml to it with your updates. here are simple steps to do it:

1. download webcenter extensions for jdevloper from here
2. add these extensions to your jdevloper follow this blog
3. create new application “webcenter portal server extension”
4. you will find 2 projects “PortalExtension” & “PortalSharedLibrary”
5. expand PortalSharedLibrary and find the web.xml under WEB-INF
6. update web.xml as you want
7. right click on project > project properties > deployment> edit
8. under web files mark the web.xml to be included in the deployment.
9. ok then ok
10. locate the MANIFEST.MF under the project
11. change the version Implementation-Version & Specification-Version
12. save
13. deploy to the server
14. restart the managed server

Change the webcenter portal language selector task flow to be links instead of popup

The current portal language selector is a popup that shows the available languages to select from .

what if you need to create links or drop down with 2 languages only?!

you can use this code and pass the locale to the parameters

 <af:commandLink styleClass="topNavLinks frlink" rendered="#{facesContext.externalContext.requestLocale eq 'en'}" partialSubmit="false" id="frlink" actionListener="#{o_w_wa_chooseLanguage.changeLanguage}" text="French">
<f:attribute name="wcLangId" value="fr"/>
</af:commandLink>
<af:commandLink styleClass="topNavLinks enlink" rendered="#{facesContext.externalContext.requestLocale eq 'fr'}" partialSubmit="false" id="enlink" actionListener="#{o_w_wa_chooseLanguage.changeLanguage}" text="English">
<f:attribute name="wcLangId" value="en"/>
</af:commandLink>
