• Create a Fusion Web Application and prepare model using Departments table of HR Schema




• Create a ViewCriteria in Departments ViewObject (For filtering viewObject using DepartmentId) and apply this viewCritria at Application Module level



To Apply ViewCriteria at AM level- Open ApplicationModule--> Select ViewObject Instance--> Click on edit button at top right side





In new window, Select viewCriteria and shuttle it to selected side. All done :)




• Create a page, drop a button and a popup with dialog in it, Drop Departments ViewObject in dialog as ADF Form




• Set content delivery of popup to lazyUncached and create a popupFetchListener in managed bean




• I have added an inputText on page to allow user input for DepartmentId
  Create a method in ApplicationModule Impl class that sets value of DepartmentId bind variable and filters Departments ViewObject

Code in AMImpl-

/**Method to set bind variable value in Department ViewObject
     * @param deparmentId
     */
publicvoidfilterDepartment(Integer departmentId){
        ViewObject deptVo=this.getDepartments1();
        deptVo.setNamedWhereClauseParam("BindDeptId", departmentId);
        deptVo.executeQuery();
}


Code in Managed Bean to call AM method-


/**
     * Generic Method to call operation binding
     * */
public BindingContainer getBindingsCont(){
return BindingContext.getCurrent().getCurrentBindingsEntry();
}

/**
     * Generic Method to execute operation Binding
     * */
public OperationBinding executeOperation(String operation){
        OperationBinding ob = getBindingsCont().getOperationBinding(operation);
return ob;
}

/**PopUp Fetch Listener , will be called on fetch event of PopUp
     * @param popupFetchEvent
     */
publicvoiddeptPopUpFetchListener(PopupFetchEvent popupFetchEvent){
        OperationBinding ob = executeOperation("filterDepartment");
//inputTextDeptIdBind is component binding of inputText that is used to get value
        ob.getParamsMap().put("departmentId", inputTextDeptIdBind.getValue());
        ob.execute();
}



• Run and check application, put any DepartmentId in inputText and hit open popup button, see popupFetchListener will be called and data will be filtered in popup

package client;

importjava.util.Scanner;

publicclassUserInput{
publicUserInput(){
super();
}

publicstaticvoidmain(String[] args){
        System.out.println("Please Enter your Name-");
        Scanner sc =new Scanner(System.in);
        String name = sc.next();
        System.out.println("Your Name is "+ name);
}

}

• Go to “Application” tab and select “Project Properties” in Jdeveloper Menu




• Go to “Run/Debug profile” and edit default Run Configuration




• Go to “Tool Setting” and check the box “Allow Program Input” and All Done :)







• Now run this program and check an additional input box appears on console

• Prepare Model using Departments table of HR Schema and dropped viewObject as table on page 


  Page structure window -

• Next step is - Create a HashMap and it's acceessors in managed bean



private HashMap reOrderMap =new HashMap();

publicvoidsetReOrderMap(HashMap reOrderMap){
this.reOrderMap= reOrderMap;
}

public HashMap getReOrderMap(){
return reOrderMap;
}



• Now we will use this HashMap as part of expression in DisplayIndex property
  See af:table xml source-






<af:tablevalue="#{bindings.Departments1.collectionModel}"var="row"
rows="#{bindings.Departments1.rangeSize}"
emptyText="#{bindings.Departments1.viewable ? 'No data to display.' : 'Access Denied.'}"
rowBandingInterval="0"
selectedRowKeys="#{bindings.Departments1.collectionModel.selectedRow}"
selectionListener="#{bindings.Departments1.collectionModel.makeCurrent}"
rowSelection="single"fetchSize="#{bindings.Departments1.rangeSize}"id="t1"
partialTriggers="::b1 ::b2">
<af:columnsortProperty="#{bindings.Departments1.hints.DepartmentId.name}"sortable="true"
headerText="#{bindings.Departments1.hints.DepartmentId.label}"id="c1"
displayIndex="#{viewScope.ReOrderTableBean.reOrderMap['DepartmentId']}">
<af:outputTextvalue="#{row.DepartmentId}"
shortDesc="#{bindings.Departments1.hints.DepartmentId.tooltip}"id="ot1">
<af:convertNumbergroupingUsed="false"
pattern="#{bindings.Departments1.hints.DepartmentId.format}"/>
</af:outputText>
</af:column>
<af:columnsortProperty="#{bindings.Departments1.hints.DepartmentName.name}"sortable="true"
headerText="#{bindings.Departments1.hints.DepartmentName.label}"id="c2"
displayIndex="#{viewScope.ReOrderTableBean.reOrderMap['DepartmentName']}"
width="120">
<af:outputTextvalue="#{row.DepartmentName}"
shortDesc="#{bindings.Departments1.hints.DepartmentName.tooltip}"id="ot2"/>
</af:column>
<af:columnsortProperty="#{bindings.Departments1.hints.ManagerId.name}"sortable="true"
headerText="#{bindings.Departments1.hints.ManagerId.label}"id="c3"
displayIndex="#{viewScope.ReOrderTableBean.reOrderMap['ManagerId']}">
<af:outputTextvalue="#{row.ManagerId}"
shortDesc="#{bindings.Departments1.hints.ManagerId.tooltip}"id="ot3">
<af:convertNumbergroupingUsed="false"
pattern="#{bindings.Departments1.hints.ManagerId.format}"/>
</af:outputText>
</af:column>
<af:columnsortProperty="#{bindings.Departments1.hints.LocationId.name}"sortable="true"
headerText="#{bindings.Departments1.hints.LocationId.label}"id="c4"
displayIndex="#{viewScope.ReOrderTableBean.reOrderMap['LocationId']}">
<af:outputTextvalue="#{row.LocationId}"
shortDesc="#{bindings.Departments1.hints.LocationId.tooltip}"id="ot4">
<af:convertNumbergroupingUsed="false"
pattern="#{bindings.Departments1.hints.LocationId.format}"/>
</af:outputText>
</af:column>
</af:table>



• Added a button on page to change dispaly index (to set value in HashMap), see managed bean code



/**Method to change display order of af:table
     * @param actionEvent
     */
publicvoidchangeOrderAction(ActionEvent actionEvent){
        reOrderMap.put("DepartmentId",2);
        reOrderMap.put("DepartmentName",4);
        reOrderMap.put("ManagerId",1);
        reOrderMap.put("LocationId",3);

}



• Run and check application, by default column ordering is this


       On click of Change Order button-



• Now again to reset columns ordering set DisplaIndex to -1 for all columns



/**Method to reset display order of af:table by setting all values to -1
     * @param actionEvent
     */
publicvoidresetOrderAction(ActionEvent actionEvent){
        reOrderMap.put("DepartmentId",-1);
        reOrderMap.put("DepartmentName",-1);
        reOrderMap.put("ManagerId",-1);
        reOrderMap.put("LocationId",-1);

}

importorg.apache.commons.net.whois.WhoisClient;

/**Method to get domain WhoIs information using Apache Commons Net API
     * @param domainName
     * @return
     */
public String getWhoisDomainInformation(String domainName){
        StringBuilder info =new StringBuilder("");
        WhoisClient whois =new WhoisClient();
try{
            whois.connect(WhoisClient.DEFAULT_HOST);
            String data = whois.query("="+ domainName);
            info.append(data);
            whois.disconnect();

}catch(SocketException e){
            e.printStackTrace();
}catch(IOException e){
            e.printStackTrace();
}
return info.toString();
}

• Now created an ADF Application and a page in viewController project
• Added library (commons-net jar file) in viewController project




• Here i am using one button and two input text, first one to enter domain name and second one is to show fetched WHOIS information


• On button click i have called above method and passed domain name (To get domain name use component binding of inputText) and to show fetched information a String variable is mapped with second inputText

See Managed Bean code and Page XML Source (How it is mapped) -



//String to store domain information and to show on page in second inputText
private String domainInfoDet;
//First Input Text component binding to get domain name in managed bean
private RichInputText domainNameBind;

publicvoidsetDomainInfoDet(String domainInfoDet){
this.domainInfoDet= domainInfoDet;
}

public String getDomainInfoDet(){
return domainInfoDet;
}

publicvoidsetDomainNameBind(RichInputText domainNameBind){
this.domainNameBind= domainNameBind;
}

public RichInputText getDomainNameBind(){
return domainNameBind;
}

/**Action Listener to execute method on button click
     * @param actionEvent
     */
publicvoidgetDomainInfoAction(ActionEvent actionEvent){
//domainNameBind is component binding of first inputText
if(domainNameBind.getValue()!=null){
            String domainName =(String) domainNameBind.getValue();
//Set WHOIS info in string to show on page (Second InputText)
            domainInfoDet = getWhoisDomainInformation(domainName);
}
}

• All Done :) , Run and check application

Next Step is create and configure Google Sheet -

importjava.io.IOException;

importjava.net.URL;

importcom.google.gdata.client.spreadsheet.SpreadsheetService;
importcom.google.gdata.data.spreadsheet.CustomElementCollection;
importcom.google.gdata.data.spreadsheet.ListEntry;

importcom.google.gdata.util.ServiceException;

publicclassPrintSpreadsheet{
publicstaticvoidmain(String[] args){
        SpreadsheetService service =new SpreadsheetService("Sheet1");
try{
            String sheetUrl =
"https://spreadsheets.google.com/feeds/list/1G3VABou70MUbRzY4vHgiDME5JW5rfo7lrAr_hZyEawU/default/public/values";

// Use this String as url
            URL url =new URL(sheetUrl);

// Get Feed of Spreadsheet url
            ListFeed lf = service.getFeed(url, ListFeed.class);

//Iterate over feed to get cell value
for(ListEntry le : lf.getEntries()){
                CustomElementCollection cec = le.getCustomElements();
//Pass column name to access it's cell values
                String val = cec.getValue("Cell1");
                System.out.println(val);
                String val2 = cec.getValue("Cell2");
                System.out.println(val2);
}
}catch(IOException e){
            e.printStackTrace();
}catch(ServiceException e){
            e.printStackTrace();
}
}
}

• Created a Fusion Web Application using Departments and Employees table of HR Schema




• Open Application Module and Web Service tab, there is a separate tab for SOAP , click on green plus icon





• In Step 1 we can set Web Service Name and Target Namespace, Also enable option to generate asynchronous methods, by default it supports synchronous service methods .
  Read in detail check this - Creating SOAP Web Services with Application Modules




• In Step 2 we can expose some built in methods and in Step 3 if we have any custom methods defined in Application Module then we can expose these methods to service interface.
  Here i have created a simple method in AMImpl to get department name from it's id and exposed this method in service




/**Method to get Department Name from Department Id
     * @param deptId
     * @return
     */
public String getDeptName(Integer deptId){
        String deptName ="Department not found";
        ViewObject deptVo =this.getDepartments1();
        Row[] filteredRows = deptVo.getFilteredRows("DepartmentId", deptId);
if(filteredRows.length>0){
            deptName = filteredRows[0].getAttribute("DepartmentName").toString();
}
return deptName;
}






• In Step 4 select viewObject that we want to expose and their methods , i have selected both Departments and Employees viewObject and enabled operation for both
  For Departments ViewObject -


 For Employee ViewObject-




• Click on Finish to create service interface and all required files 




• Now to run and check web service , Expand Application Module root and there is a  service implementation java class SoapWebServServiceImpl.java  , Right click on this and choose Run




• On running you'll see an URL in weblogic log tab, click on that url it will open HTTP Analyzer tool and there you'll see list of all operation , here i have selected GetByKey operation of Departments viewObject


          Here i passed depatmentId as key parameter and you can see web service response


• Again i selected create operation for Departments viewObject and provided all parameters and click Send Request button



                  and result in database table




• This time i am checking custom method defined in application module to get Department Name

• Created a Fusion Web Application using Departments table of HR Schema


• Open Application Module and click on Web Service tab, there is a separate tab for REST, Click on green plus icon- It show an error dialog that asks to define a version




• We have to define release version and name in adf-config.xml to create REST Web Service




• Again go back to Application Module and click on green plus icon of REST tab, a dialog appears to create REST Resource - Provide resource name and select release version




• On click of OK and IDE generates a separate project for REST Web Service and a REST Resource file under Application Module to configure custom methods , viewObjects and attributes etc.
  
  
  
  REST Resource file -
  
• Now to run and check web service ,Right click on RESTWebService project and choose Run




• On running you'll see an URL in weblogic log tab, click on that url, it will open HTTP Analyzer tool




• Now to access REST Resource we have to add version name and Resource Name in above url like this- http://127.0.0.1:7101/RestWebServApp-RESTWebService-context-root/rest/Jdev12.2.1/Department , select GET in method and  click on Send Request button and you can check response in right panel
  
  
• We can also pass Department Id as parameter in url to get specific department detail

• Create a Fusion Web Application using Employees table of HR Schema


• Create a page and drop Employees viewObject as pieChart on page




• Select pieChart in structure window and in property inspector set DataSelection property to single and create a Selection Listener in managed bean




• Copy value property of pieChart, it'll be like this- #{bindings.Employees1.collectionModel} Now see code in selection listener that sets selected row as current row and then from iterator we can get current row and from that row we can get all attributes




importjavax.el.ELContext;

importjavax.el.ExpressionFactory;

importjavax.el.MethodExpression;
importjavax.el.ValueExpression;

publicstatic Object invokeEL(String el, Class[] paramTypes, Object[] params){
        FacesContext facesContext = FacesContext.getCurrentInstance();
        ELContext elContext = facesContext.getELContext();
        ExpressionFactory expressionFactory = facesContext.getApplication().getExpressionFactory();
        MethodExpression exp = expressionFactory.createMethodExpression(elContext, el, Object.class, paramTypes);

return exp.invoke(elContext, params);
}

/**

        FacesContext facesContext = FacesContext.getCurrentInstance();
        ELContext elContext = facesContext.getELContext();
        ExpressionFactory expressionFactory = facesContext.getApplication().getExpressionFactory();
        ValueExpression exp = expressionFactory.createValueExpression(elContext, el, Object.class);

return exp.getValue(elContext);
}

/**Custom Selection Listener for dvt:pieChart
     * @param selectionEvent
     */
publicvoidpieChartSelectionListener(SelectionEvent selectionEvent){
// Makes selected slice as current row
        invokeEL("#{bindings.Employees1.collectionModel.makeCurrent}",new Class[]{ SelectionEvent.class},new Object[]{
                 selectionEvent });
// Get the selected row (Use pie chart iterator name)
        Row selectedRow =(Row) evaluateEL("#{bindings.Employees1Iterator.currentRow}");// get the current selected row
// Get any attribute from selected row
        System.out.println("Selected Employee is-"+ selectedRow.getAttribute("FirstName"));

}


}




• Run and check application, pie looks like this
  
  
  Select any slice-
  
  It's Employee name appears on log
  
  

• Create a Fusion Web Application with default Model and ViewController project


• Right click on Model project , Select New--> From Gallery--> Business Tier--> Web Services and select Web Service Data Control SOAP/REST 


• It opens WSDL creation wizard , First Step is to provide Web Service Name and URL




• Click on next and in second screen select the methods to expose in Data Control that will be further used by application




• In third step we can set return type of Web Service response , there are two options -XML and CSV. Leave it as default XML




• Click on Finish button to generate DataControl.dcx (It is created when DataControl is registered on Business Service not on ADF Business Components) and WSDL document






• Creation of WSDL is done now create a page in view controller project and expand DataControls menu , there we will see a data control created for CountryWebServices 




• Drag and drop GetCountries operation on page as a button and expand this operation and drop String as output text formatted to show response of webservice






• In same manner drop another method as parameter form as it has one input parameter that takes country name as input and shows it's currency as output.
