the problem you're not loading list content anywhere. best place doing in @postconstruct on managed bean. also, since invoke ajax calls on page, better if set scope of managed bean @ least @viewscoped:
@managedbean @viewscoped public class ordersmb { //attributes, methods, getters, setters... @postconstruct public void init() { try { getorderlists(); } catch (namingexception ne) { //handle error here... } } } in case want load data using ajax call (as looks want/need), forgot update component display data. can achieve using render attribute of <f:ajax>. in case, must provide full id of component since you're updating component outside form.
<h:form id="hidden" style="display:none"> <h:commandlink id="link"> <f:ajax event="click" listener="#{order.getorderlists}" render=":frmdata" /> </h:commandlink> </h:form> <!-- html/jsf content here... --> <h:form id="frmdata"> </h:form>
