display Freemarker in JSP in explorer?

esource — Wed, 26 May 2010 17:10:54 GMT

I wanted to use Freemarker in JSPs in explorer. How would I do this? How would I create a dialog for example?

I tried it but received an error.

I want to use space and companyhome and other named objects, but instead I get the error :

Expression space is undefined

you need to use the default model provided by Alfresco. You are probably not using the default model.

Maybe that is the problem. I have created a dialog and for this dialog want to use freemarker to display the node information in the dialog. I have created a backing bean for this dialog. Does that somehow turn off the default named objects as you call them? Can I use freemarker and the default named objects in a dialog?

This works great, check how to define custom model. and specify space and document nodes. this would fix it .


<r:template template="alfresco/templates/example.ftl" model="#{MyBean.templateModel}" />
Example Bean code to return a model:

  /**
   * Returns a model for use by a template on the Document Details page.
   *
   * @return model containing current document and current space info.
   */
  public Map getTemplateModel()
  {
     Map<String, Object> model = new HashMap<String, Object>(4, 1.0f);
     
     model.put("document", getDocument().getNodeRef());
     model.put("space", this.navigator.getCurrentNode().getNodeRef()); //define space that you need hire.
     model.put(TemplateService.KEY_IMAGE_RESOLVER, imageResolver);
     
     return model;
  }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I'm really having difficulty here. I am trying to display freemarker in a JSP in explorer.

my jsp

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="/WEB-INF/repo.tld" prefix="r" %>

<html>
  <body>
 
  <f:view>
    <h:form>
      <r:template template="alfresco/templates/simple.ftl" />
    </h:form>
  </f:view>
 
  </body>
</html>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

simple.ftl


<h1>hello how are you</h1>
‍‍‍

I get an error message when I try to display the jsp in a dialog:

Would someone have a suggstion as to why I am receiving the error or how I may correct the error?

Re: display Freemarker in JSP in explorer?

esource — Thu, 03 Jun 2010 11:02:14 GMT

changed my jsp to

<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="/WEB-INF/repo.tld" prefix="r" %>

Thank you very much for your post! But where should I get 'getDocument()'? I get the error that getDocument() is undefined. I also get the error message that imageResolver cannot be resolved.

Re: display Freemarker in JSP in explorer?

savic_prvoslav — Thu, 03 Jun 2010 13:15:06 GMT

you can inject Browsebean into your bean and getCurent documetn like:

browsebean.getDocument();

and finally imageres

protected TemplateImageResolver imageResolver = new TemplateImageResolver() {
   public String resolveImagePathForName(String filename,
      FileTypeImageSize size) {

       FacesContext context = FacesContext.getCurrentInstance();
       ServletContext servletContext = ((HttpServletRequest) context
          .getExternalContext().getRequest()).getSession()
          .getServletContext();
       return FileTypeImageUtils.getFileTypeImage(servletContext,
          filename, size);
   }
    };‍‍‍‍‍‍‍‍‍‍‍‍

put this into your bean.
hope this helps.

Re: display Freemarker in JSP in explorer?

esource — Fri, 04 Jun 2010 14:57:36 GMT

Yes, it helps very much. Thank you! Thank you for your posts!

Now, the question I have is how can I pass a list of Nodes, a java.util.List of Nodes to my freemarker template and have it display the list as well as information from the list?

I assume I would have to put this List in the model.

I tried:


   model.put("nodeList", this.browseBean.getContent());
‍‍‍

But this returns an error from Alfresco :

16:51:45,208 User:admin ERROR [ui.common.Utils] 05040003 Error during processing

Re: display Freemarker in JSP in explorer?

savic_prvoslav — Sat, 05 Jun 2010 02:10:22 GMT

i do not know that this is possible, because space is made for this reason .

Can you tell how would you get this list of nodes?

Re: display Freemarker in JSP in explorer?

esource — Sun, 06 Jun 2010 17:08:04 GMT

I perform a search in Alfresco from which I receive a search result list. I then modified browse.jsp, adding a button


<td style="padding-right:4px" align=right>
      <%– custom button  –%>
      <nobr><a:actionLink value="CustomButton" image="/custom/images/icons/customButton.png" style="white-space:nowrap" actionListener="#{CustomDialog.myMethod}" id="mylink1" /></nobr>
</td> 
‍‍‍‍‍‍

Clicking this button opens CustomDialog calling myMethod:


public class CustomDialog extends BaseDialogBean {

     Map<String, Object> templateModel;       
   protected TemplateImageResolver imageResolver;

   public void myMethod(ActionEvent event) {
      imageResolver = new TemplateImageResolver() {
            public String resolveImagePathForName(String filename,
               FileTypeImageSize size) {

                FacesContext context = FacesContext.getCurrentInstance();
                ServletContext servletContext = ((HttpServletRequest) context

this attempts to open a dialog, but an error results from the call to

model.put("nodeList", this.browseBean.getContent());

Re: display Freemarker in JSP in explorer?

If I remove the call to :


model.put("nodeList", this.browseBean.getContent());
‍‍‍

no error occurs. And in fact I can pass values from CustomDialog to the freemarker template via the model as an example:


model.put("hello","hello, how are you");
‍‍‍

And I also have access to the node results from the search, but the values have to be transcribed, copied into my own custom node as example:


     public Map getTemplateModel()
     {
          nameList = new java.util.ArrayList<String>();        
          customList = new java.util.ArrayList<customNode>();      
          List<Node> searchResults = this.browseBean.getContent();  
          Integer searchResultsCount = searchResults.size();
         for(ListIterator<Node>li=searchResults.listIterator(); li.hasNext(); ) 
         {
               Node resultNode = li.next();
               String Name = resultNode.getName();
                         nameList.add(Name);
                         customList.add(new customNode(resultNode));
          }

           Map<String, Object> model = new HashMap<String, Object>(4, 1.0f);
           model.put("names", nameList);
           model.put("custom", customList);
                     //model.put("nodeList", this.browseBean.getContent());
           model.put(TemplateService.KEY_IMAGE_RESOLVER, imageResolver);
           
           return model;
     }

So, I can get search results to display in freemarker but I cannot send the nodes directly. It seems the nodes have to be copied into custom objects.

you can perform a search into freemarker with

childrenByLuceneSearch
Returns a map capable of executing a search against the entire repository based on a Lucene search string. It returns a sequence of nodes which represent the objects from the results of the search, such as companyhome.childrenByLuceneSearch["TEXT:alfresco* AND TEXT:tutorial*"]. The value can be any valid Lucene search string supported by Alfresco. Note that you may need to escape Lucene specific characters. Note that the entire repository is searched: the current node is only used as an access point to retrieve the search object.

http://wiki.alfresco.com/wiki/Template_Guide you have this hire.
