Jsf DataTable and Checkbox problems

Dear Experts,

I have jsf DataTable and checkbox problem
I have a List listCountries with fields: countryId & countryNm

            <h:dataTable value="#{pLM0001.listCountries}"
                              var="f0001"
                              binding="#{pLM0001.htmlDataTableCountry}"
                              border="1">
                  <h:column>
                        <h:outputText value="#{f0001.countryid}"></h:outputText>
                  </h:column>
                  <h:column>
                        <h:outputText value="#{f0001.countryNm}"></h:outputText>
                  </h:column>
                  <h:column>
                        <h:selectBooleanCheckbox value="#{pLM0001.bolSelected}">
                        </h:selectBooleanCheckbox>
                  </h:column>
            </h:dataTable>

End users can pick the countries they want to select.
The problem is, how can I get which countries are selected?

I am still a rookie in jsf and java environment, please kindly help :).
