Just make sure whatever value they are binding back to has the value true.

Instead of asking how to do something. Think about your problem and try to write something. Then when you get stuck post what you have and ask why it doesn't work.

here is my java code which i wish it check my checkbox but it didnt.

        private long positionTypeId;

     public long getPositionTypeId() {
          if (this.positionType != null)
               return this.getPositionType().getId();
          else
               return 0;
     }

     public void setPositionTypeId(long value) {
          this.positionTypeId = value;

          this.positionType = this.entityManager.find(PositionType.class,
                    this.positionTypeId);
          
          this.selectedOptions.clear();
          
          for (PositionTypeSeverity sev : this.positionType.getPositionTypeSeverity()) {
               Long sev_id = sev.getId();
               
               this.selectedOptions.add(sev_id);
          }
          

     }

<h:form id="positionTypeSeverityAdd" styleClass="edit">
<rich:panel>
   <h:panelGrid>
<h:outputText value="#{positionTypeSeverityConversation.positionType.name}" />

<h:selectManyCheckbox id="severity" value="#{positionTypeSeverityConversation.selectedOptions}">
<s:selectItems var="_ser" value="#{positionTypeSeverityConversation.severities}"
label="#{_ser.name}" itemValue="#{_ser.id}"  />
</h:selectManyCheckbox>
</h:panelGrid>
</rich:panel>

<h:commandButton id="save" value="Save"
     action="#{positionTypeSeverityConversation.save()}"
     style="FONT-FAMILY: 'Abyssinica SIL';">
</h:commandButton>

<s:button view="/setting/hr/PositionType.xhtml" id="cancelAdd"
     value="Cancel">
     <f:param name="positionTypeId" value="#{positionTypeId}" />
</s:button>
</h:form>
