Navigating to (open) specific tab in af:panelTabbed programmatically -Oracle ADF

Hello All,
This post is about a development requirement - how to move (navigate or open) to a specific tab in panel tabbed in Oracle ADF?
Suppose i have to open second tab of af:panelTabbed on a button click, so see how to do this using ADF Faces

Create a Fusion Web application and a page to drop panel tabbed and a button

now bind panel tabbed and it's showDetailItem to managed bean, in order to use disclosed property and to get client id

    //Binding of Panel Tabbed
    private RichPanelTabbed panelTabBind;

    public void setPanelTabBind(RichPanelTabbed panelTabBind) {
        this.panelTabBind = panelTabBind;
    }

    public RichPanelTabbed getPanelTabBind() {
        return panelTabBind;
    }

    /**
     * @Method to disclose (open) specific tab
     * Pass the binding of af:showDetailItem that you want to open
     */
    public void setDisclosedFirstTab(RichShowDetailItem tabBind) {
        RichPanelTabbed richPanelTabbed = getPanelTabBind();
        for (UIComponent child : richPanelTabbed.getChildren()) {
            RichShowDetailItem sdi = (RichShowDetailItem) child;
            if (sdi.getClientId().equals(tabBind.getClientId())) {
                sdi.setDisclosed(true);
            } else {
                sdi.setDisclosed(false);
            }
        }
        AdfFacesContext.getCurrentInstance().addPartialTarget(panelTabBind);
    }

Now see the code written on button action- here i have checked that which tab is currently disclosed? and based on that i have passed next tab binding to this method

    /**Method to be called on Navigate Button
     * @param actionEvent
     */
    public void naviGateButtonAction(ActionEvent actionEvent) {
        if (firstTabBind.isDisclosed()) {
            setDisclosedFirstTab(secTabBind);
        } else if (secTabBind.isDisclosed()) {
            setDisclosedFirstTab(thirdTabBind);
        } else {
            setDisclosedFirstTab(firstTabBind);
        }
    }

now run your page and see navigation in af:panelTabbed

Detect browser & platform information (name,version), server and client IP details in Oracle ADF

Hello All,
This is post is about getting browser details (version, name ) , platform details (Operating System details) ,server and client IP addresses in Oracle ADF Application
sometimes we need these small but important details -

Code to get this information-

        RequestContext requestCtx = RequestContext.getCurrentInstance();
        Agent agent = requestCtx.getAgent();
        String version = agent.getAgentVersion();
        String browser = agent.getAgentName();
        String platform = agent.getPlatformName();
        String platformVersion = agent.getPlatformVersion();
        FacesContext fctx = FacesContext.getCurrentInstance();
        HttpServletRequest request = (HttpServletRequest) fctx.getExternalContext().getRequest();
        StringBuilder detailMsg = new StringBuilder("<html><body><b>Browser Agent and Ip address details</b><br>");
        detailMsg.append("<ul><li><b>Browser-</b>" + browser + "</li><li><b>Version-</b>" + version +
                         "</li><li><b>Plateform-</b>" + platform + "</li>");
        detailMsg.append("<li><b>Plateform Version-</b>" + platformVersion + "</li><li><b>Server IP-</b>" +
                         request.getLocalAddr() + "</li><li><b>Client IP-</b>" + request.getRemoteAddr() +
                         "</li></ul>");
        detailMsg.append("</body></html>");
        FacesMessage errMsg = new FacesMessage(detailMsg.toString());
        errMsg.setSeverity(FacesMessage.SEVERITY_INFO);
        fctx.addMessage(null, errMsg);

See the output-

Creating and Exporting hierarchical data to excel using dvt:pivotTable & dvt:exportPivotTableData in Oracle ADF

Hello All,
This post is about exporting tree structured(hierarchical ) data to an excel file.
suppose we have export department wise detail of employees , we can achieve this in ADF using pivot table (<dvt:pivotTable>)

What is pivot tabel (oracle docs)-

UIComponent class: oracle.adf.view.faces.bi.component.pivotTable.UIPivotTable
Component type: oracle.dss.adf.pivotTable.PivotTable
The Pivot Table supports the display of multiple nested attributes on a row and column header. In addition, the Pivot Table supports the ability to dynamically change the layout of the attributes displayed in the row or column headers via drag and drop pivoting.
now see the implementation part -

Create a Fusion Web Application using HRSchema , for this sample app i have created a view (Department Wise Employees) to export data

CREATE OR REPLACE FORCE EDITIONABLE VIEW "APP_USR"."DEPT_EMP" ("DEPARTMENT_NAME", "EMPLOYEE_NAME", "SALARY") AS 
  SELECT A.DEPARTMENT_NAME, B.FIRST_NAME,B.SALARY FROM DEPARTMENTS A, EMPLOYEES B WHERE A.DEPARTMENT_ID=B.DEPARTMENT_ID (+);

Prepare model using this view

Create a page and drop this view as pivot table (ADF Faces component) from data control

Now configure pivot table (set row & column attributes, insert appropriate drilling) - see the snaps

Now run your page and see working pivot table - here pivot table is created successfully

Drop a button and a <dvt:exportPivotTableData> under button to export pivot table

<af:commandButton text="Export" id="b1">
                    <dvt:exportPivotTableData type="excelHTML" exportedId="pt1" filename="Dep_Empl.xls"
                                              title="PivotTable export"/>
                </af:commandButton>

Run your page and click on export button and see your tree structured data in exported excel file
