When i click on any link it should Open in the same New Window in JSF, Primefaces

In my JSF page i have few Links{link1,link2,link3,link4}-{Student Id's}.

What i tried is when i click on the Link it Opens the Student-Information in a "NEW WINDOW".

When i am clicking on the next Link it is Opening a New Window,but i want to open in the Same New Window i.e., the TARGET should be the Same NEW Window which is opened.

Diagramatical Representation:

My Piece of Code which i had tried from collecting things from STACKOVERFLOWOpen Page in New Window :

<p:dataTable id="studentDtTble" var="studData" value="#{studentController.dataList}">
        <p:columnGroup type="header">
            <p:row>
                    <p:column headerText="StudentId"></p:column>
                    <p:column headerText="StudentName"></p:column> 
                    <p:column headerText="Add" ></p:column>     
            </p:row>
        </p:columnGroup>
            <p:column>
                <p:commandLink id="sidlink" action="/studentinfo.xhtml" target="_blank">  
                    <h:outputText value="#{studData.studentId}" styleClass="txtlink" />
                </p:commandLink>
            </p:column>
            <p:column>
               <h:outputText value="#{studData.studentName}" />
            </p:column>
            <p:column >
                <p:selectBooleanCheckbox value="#{studData.add}" />
            </p:column>
    </p:dataTable>

Edited After @Nosnhoj Reply :When i Click on any of the SID Link then there Details Should Opened in the "Same NEW Window".
