You can always use something like DWR (Direct web remoting) for AJAX call in your app.

This is what worked for me.
<button type="button" name="identifierRow" id="identifierRow" th:value="${idBeanStat.index}" th:onclick="'javascript:doAjaxCallRemoveIdentifier(\'' + ${idBeanStat.index} + '\');'">Remove</button> <script> doAjaxCallRemoveIdentifier(id){ //Ajax call here } </script>
Hope this helps someone else.

I am using SPring mvc 3 with Thymeleaf.I have a list in my jsp page and each row in the bean is accompanied by a button.When I click on that button I want to get the index of that row.I am not able to do so.
I have the following list in my Jsp page
<tr th:each="idBean : ${idBeanLst}" > <td th:text="${idBeanStat.count}" id="count"></td> <td th:text="${idBean.identifierId}" id="idenId"></td> <td th:text="${idBean.idNumber}" id="idNumber"></td> <td th:text="${idBean.issueLocation}" id="issueLocation"></td> <td th:text="${idBean.issueDate}" id="issueDate"></td> <td th:text="${idBean.expiryDate}" id="expDt"></td> <td> <td> <button type="button" name="identifierRow" id="identifierRow" th:value="${idBeanStat.index}" onclick="doAjaxCallRemoveIdentifier()">Remove</button> </td> function doAjaxCallRemoveIdentifier() { alert('in here'); var idNumber = $('#idNumber').val(); var issueLocation = $('#issueLocation').val(); var issueDate = $('#issueDate').val(); var expiryDate = $('#expiryDate').val(); var identifierRow = $('#identifierRow').va(); alert(identifierRow); var url = '/SpringUI/spring/removeIndentifier/'; $("#content").load(url, { 'identifierRow' : identifierRow }, function () { $('#idNumber').val(''); $('#issueLocation').val(''); $('#issueDate').val(''); $('#expiryDate').val(''); }); }
How can I send the index number of this arraylist indside the function doAjaxCallRemoveIdentifier().How can I do that?

The reason I want to avoid using jquery is that
1) I have to explicitly send the values of the of each attribute of a bean and then receive them inside the method in the controller.
I would be much simpler if I could just use something like this in the method signature in the method that gets called by the ajax request
@RequestMapping(value="/addIndentifier",method=RequestMethod.POST) public String addIndentifier(@ModelAttribute IdentiferBean idenBean){ }
If I can do something like this, then, i would get the values that the user entered in the form through the Bean mentioned in @ModelAttribute .

I am using Thymeleaf in my App.To process ajax requests I am using jquery to call the contrller .Like this :
function doAjaxCallIdentifier() { var idNumber = $('#idNumber').val(); var issueLocation = $('#issueLocation').val(); var issueDate = $('#issueDate').val(); var expiryDate = $('#expiryDate').val(); var url='/SpringUI/spring/addIndentifier/'; $("#content").load(url,{'idNumber':idNumber,'issueLocation':issueLocation,'issueDate':issueDate,'expiryDate':expiryDate},function() { $('#idNumber').val('');$('#issueLocation').val('');$('#issueDate').val('');$('#expiryDate').val(''); }); }
Here is the methos in my controller

@RequestMapping(value="/addIndentifier",method=RequestMethod.POST) public String addIndentifier(@RequestParam(value = "idNumber") String idNumber, @RequestParam(value = "issueLocation") String issueLocation,@RequestParam(value = "issueDate") String issueDate, @RequestParam(value = "expiryDate") String expiryDate,Model model,HttpSession session) { ModelMap modelMap=(ModelMap)session.getAttribute("modelMap"); if(modelMap!=null) { PersonTO personTO=(PersonTO)modelMap.get("personTO"); IdentifierBean identifierBean=new IdentifierBean(); identifierBean.setIdNumber(idNumber); identifierBean.setIssueLocation(issueLocation); identifierBean.setIssueDate(issueDate); identifierBean.setExpiryDate(expiryDate); personTO.getIdBeanLst().add(identifierBean); model.addAttribute("idBeanLst", personTO.getIdBeanLst()); System.out.println("personTO.idbean size"+personTO.getIdBeanLst().size()); } return "personidentifier :: resultsList"; }
Is it possible to avoid jquery in Thymeleaf for the ajax call?

B) If you are expecting the valueChangeEvent listener to be fired automatically when the user updates the GUI, that's not how that works, either. JSF is based on HTTP, HTTP doesn't connect-and-converse the way client/server does, but instead works with paired request/response messages, with requests being initiated by commandButtons, commandLinks or explicit entry of a URL in the user's browser navigation control. The valueChangeListener gets invoked ONLY if all of the submitted data is valid, and then only if the control that it is attached to has an actual change of value.

Sorry I did not get this point. I can see that the control in getting tranferred to the method bound to the ManagedBean when the value is chaged in GUI. The problem is that the bean property that is getting set in the method is not getting retrieved in the GUI

@Tim Holloway I apologize for being impatient.

Despite some questionable examples from Oracle, JSP's JSTL and JSF are a bad mix.

I have changed my code in the JSP page in the following way
<h:outputText rendered="#{concernBean.validRole=='INVALID'}"> <script> alert("You do not have the priviledge to perform this action"); document.getElementById("save").disabled=true; </script> </h:outputText> <h:outputText rendered="#{concernBean.validRole=='VALID'}"> <script> document.getElementById("save").disabled=false; </script> </h:outputText>

In the method bound to ValueChangeListener I have done the necessary adjustments
public void checkValidRole(ValueChangeEvent e){ LoginBean loginBean = (LoginBean) FacesContext.getCurrentInstance(). getExternalContext().getSessionMap().get("loginBean"); boolean flag =false; Iterator itr =loginBean.getRoleNames().iterator(); while (itr.hasNext()){ /*some logic */ validRole="VALID"; } } } if(!flag){ validRole="INVALID"; } }
After doing this also it is not working.

Any idea on this issue?

I have added a value chage listener in a JSP page in JSF 2.0 and in the method I have set a bean property like this
<tr:selectOneChoice label="Concern Type:" showRequired="true" id="concernType" unselectedLabel="Please Select" value="#{concernBean.concern.concernType.concernTypeCode}" disabled="#{concernBean.disableConcern}" autoSubmit="true" valueChangeListener="#{concernBean.checkValidRole}"> <f:selectItems value="#{concernBean.concernType}"/> </tr:selectOneChoice> <c:if test="${concernBean.showAlert==true}"> <script> alert("Only Global Account Manager can add group concern "); document.getElementById("save").disabled=true; </script> </c:if> <c:if test="${concernBean.showAlert==false}"> <script> document.getElementById("save").disabled=false; </script> </c:if>
The checkValidRole method is like this :
public void checkValidRole(ValueChangeEvent e){ logger.info("inside checkValidRole"); LoginBean loginBean = (LoginBean) FacesContext.getCurrentInstance(). getExternalContext().getSessionMap().get("loginBean"); boolean flag =false; Iterator itr =loginBean.getRoleNames().iterator(); while (itr.hasNext()){ String roleName=(String)itr.next(); if(e.getNewValue().toString().equalsIgnoreCase("GRP_CONCRN")|| e.getNewValue().toString().equalsIgnoreCase("COMP_CONCRN")){ if(roleName.equalsIgnoreCase("Global Account Manager")){ setShowAlert(false); flag =true; break; } } } if(!flag){ setShowAlert(true); } }

I can see that inside the checkValidRole method when flag is false setShowAlert is getting set to true but in the JSP page the bean property is not getting retrieved properly.It is always showing false.I can see the follwing snippet when I do a view source of the page in the browser
document.getElementById("save").disabled=false;
The corresponding bean concernBean is registered as a session bean
What mistake am I doing here?

I am trying to send JSON object to and from a restful webservice implemented through a Jersey API
Here is my code for the service
@Path("/hello") public class Hello { @POST @Path("{id}") @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.APPLICATION_JSON) public JSONObject sayPlainTextHello(@PathParam("id")JSONObject inputJsonObj) { String input = (String) inputJsonObj.get("input"); String output="The input you sent is :"+input; JSONObject outputJsonObj = new JSONObject(); outputJsonObj.put("output", output); return outputJsonObj; } }

Here is my code for the client
ClientConfig config = new DefaultClientConfig(); Client client = Client.create(config); WebResource service = client.resource(getBaseURI()); JSONObject inputJsonObj = new JSONObject(); inputJsonObj.put("input", "Value"); System.out.println(service.path("rest").path("hello").accept(MediaType.APPLICATION_JSON).entity(inputJsonObj).post(JSONObject.class,JSONObject.class));


But this shows the following error

Exception in thread "main" com.sun.jersey.api.client.ClientHandlerException: com.sun.jersey.api.client.ClientHandlerException: A message body writer for Java type, class java.lang.Class, and MIME media type, application/octet-stream, was not found

Can anybody help?Is there any tutorial that explains how to do this?

I solved the above problem by using "${sessionScope.userList}" instead of "#session.userList"
<display:table export="true" id="data" name="${sessionScope.userList}" requestURI="/checkLogin.action" pagesize="10" > <a href="#" rel="tooltip" content="<span> Rank:<s:property value="#data.rank" /><br/> Name: <s:property value="#data.name" /><br/> </span>"> <display:column property="rank" title="Rank" sortable="true" /></a> <display:column property="name" title="Name" sortable="true" /> <display:column property="id" title="Age" sortable="true" /> <display:column property="price" title="Price" sortable="true" /> </display:table>
But the problem that I have now is that when I use <s:property> tag inside <display:table> tag the value is not getting displayed .So I can see the values in <display:column> tag but not the ones that I try to display using <s:property> tag.

I have the following arraylist in my action class
ArrayList<Data> userList = new ArrayList<Data>(); userList.add(new Data(1, "A", 53, 40.0)); userList.add(new Data(2, "B", 78, 37)); userList.add(new Data(3, "C", 69, 35)); request.getSession().setAttribute("userList", userList);
I try to display it using display tables tag in the jsp page but no value is getting displayed

<display:table export="true" id="data" name="#session.userList" requestURI="/checkLogin.action" pagesize="10" > <display:column property="rank" title="Rank" sortable="true" /> <display:column property="name" title="Name" sortable="true" /> <display:column property="id" title="Age" sortable="true" /> <display:column property="price" title="Price" sortable="true" /> </display:table>

I am using java mail api to send emails in my application.The email is getting sent properly.But I am struggling with the content where I have a jsp page that includes 2 other jsp pages(header and footer).How to send this jsp page as the content.Currently I am using the following way to set the content of the emailStringBuffer sb = new StringBuffer(); sb.append("<HTML><HEAD><TITLE>Completion</TITLE></HEAD>\n"); sb.append("<BODY BGCOLOR=\"WHITE\"><TABLE width='100%'>"); .....
Certainly this is extremely tedious.Is there a way out?I am calling the content setter method (for the email) from an action class in Struts 2

I have a jsp page with 2 forms(the forms reside in 2 different jsp page and I have just included the pages in the parent jsp page ).Now , if I click a particular submit button the corresponding action gets called but the entire page gets refreshed.What I want is that partial refresh of the pages .How can I do that(I am using struts 1.2)?

Here is my code to unmarshall
JAXBContext jc = JAXBContext.newInstance("com.cts.mib.security");//this package contains the object factory class Unmarshaller u = jc.createUnmarshaller(); JAXBElement element = (JAXBElement) u.unmarshal(xmlInputStream);//xmlInputStream contains the xml to be unmarshalled com.cts.mib.security.DWLAdminService dwlService = (com.cts.mib.security.DWLAdminService) element.getValue(); return dwlService;
Here is my OjectFactory class
@XmlRegistry public class ObjectFactory { private final static QName _QNAME = new QName("", "DWLAdminService"); public ObjectFactory() { } public DWLAdminService createItem() { return new DWLAdminService(); } @XmlElementDecl(namespace = "", name = "DWLAdminService") public JAXBElement<DWLAdminService> createItem(DWLAdminService value) { return new JAXBElement<DWLAdminService>(_QNAME, DWLAdminService.class, null, value); } }
And here is my DWLAdminService class
@XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "DWLAdminService", propOrder = { "responseControl", "txResponse", "tcrmTx", }) @XmlRootElement() public class DWLAdminService extends BaseBean implements Serializable { private static final long serialVersionUID = 1L; @XmlElement(name = "ResponseControl") private ResponseControl responseControl = null; @XmlElement(name = "TxResponse") private TxResponse txResponse = null; @XmlElement(name = "TCRMTx") private TCRMTx tcrmTx = null; public ResponseControl getResponseControl() { return responseControl; } public void setResponseControl(ResponseControl responseControl) { this.responseControl = responseControl; } public TxResponse getTxResponse() { return txResponse; } public void setTxResponse(TxResponse txResponse) { this.txResponse = txResponse; } public TCRMTx getTcrmTx() { return tcrmTx; } public void setTcrmTx(TCRMTx tcrmTx) { this.tcrmTx = tcrmTx; } }
While unmarshalling I find that the fileds in TxResponse does not get set but fields in responseControl get set.!!What can be the possible reason for that..?
