Providing anchor to columns in a datatable

[Harshit mohan]

Hi All,

My requirement is that i should display a report in form of a datatable(in tabular format) and i want to provide hyperlink to 1st columns for each row so that when that link is clicked some other page is opened with some parameter passed from that link. For that my jsp file is below

   

<f:view>
<h:form>
 <h:dataTable
binding="#{customerBS.hdt}" value="#{customerBS.customers}" var="c"
border="2" cellpadding="1">
<h:column>
<f:facet name="header">
<h:outputText value="Name"></h:outputText>
</f:facet>
<h:commandLink value="#{c.name}" action="#{c.go}">
</h:commandLink>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Address"></h:outputText>
</f:facet>
<h:outputText value="#{c.address}"></h:outputText>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="EmailID"></h:outputText>
</f:facet>
<h:outputText value="#{c.emailid}"></h:outputText>
</h:column>
</h:dataTable>
</h:form>
</f:view>


 

Here is the CustomerBS class

 

public class CustomerBS {
 
private Connection connection;
private String connstring;
private String user;
private String pass;
private Message msg=null;
private List<SelectItem> names=null;
private List<Customer> customers=null;
private HtmlDataTable hdt=null;
private Customer customer;
 
-----
-----
-----
public String go(){
 
customer=new Customer();
customer=(Customer)hdt.getRowData();
ExternalContext ec=FacesContext.getCurrentInstance().getExternalContext();
ec.getRequestMap().put("custname", customer.getName());
System.out.println("in go");
return "proceed";
 
}
 
 
public HtmlDataTable getHdt() {
return hdt;
}
 
 
public void setHdt(HtmlDataTable hdt) {
this.hdt = hdt;
}
}

Below is my faces-config.xml file

<to-view-id>/linkdetails.jsp</to-view-id>
</navigation-case>
</navigation-rule>   
</faces-config>

Its not working and i have tried almost all the combinations. Please suggest what is wrong in this.Everytime when i click the link the same page opens but with null rows and columns.
