목표여러 탭

로 리디렉션.

진행 지금까지 내가

public void printReceipts() { 

     // PDF1 
     // PDF2 
     // PDF3 

     redirectToPage(PDF1_URL); // Works good 

     redirectToPage(PDF2_URL); // Exception - Multiple redirect exceptions 

     redirectToPage(PDF3_URL); 
    }

.xhtml

만

콩 하나 개의 탭으로 리디렉션 3 개 PDF 파일을 생성 할 수 있지만 수 있어요

<h:commandLink styleClass="btn btn-success" action="#{cartController.printReceipts()}" target="_blank" value="Print" />

PDF 내용을 뒷받침 속성으로 저장하십시오. 탭을 사용하면 단 하나의 PDF 만 렌더링하면됩니다. 세 개의 브라우저 탭을 사용하는 대신 UITabView 구성 요소를 사용하고 페이지를 생성 할 때 Bean에 저장된 PDF 파일 이름에 액세스하십시오.

의 관리 빈 :

@Named 
@SessionScoped 
public class TabbedPDFViewBean 
{ 
    private String[] fileNames = new String[3]; 

    public String getFileName0() { fileNames[0]; } 
    public void setFileName0(String fileName_) { fileName[0] = fileName_; } 
    public String getFileName1() { fileNames[1]; } 
    public void setFileName1(String fileName_) { fileName[1] = fileName_; } 
    public String getFileName2() { fileNames[2]; } 
    public void setFileName2(String fileName_) { fileName[2] = fileName_; } 

}

facelet 다음 번 PDF 링크를 엽니 다 자바 스크립트의 비트를`PDF1PDF2에 대한 링크가 있습니다 '하고 포함 페이지로

<p:tabView> 
    <p:tab title="PDF1"> 
    <iframe src="#{tabbedPDFViewBean.fileName0}" width="600" height="400" scrolling="no"></iframe> 
    </p:tab> 
</p:tabView>
