Javascript Controller Fails

[mduduzi]

Hi,

I am executing a script in the javascript console and it works. When I use the very same script in a web script and deploy it in web script extension folder it compains. Pasted below is the part of the script that fails and the error log:

var ctx =Packages.org.springframework.web.context.ContextLoader.getCurrentWebApplicationContext();
var qname = Packages.org.alfresco.service.namespace.QName;
var def = Packages.org.alfresco.service.cmr.dictionary;
var ns = Packages.org.alfresco.service.namespace.NamespaceService;
var iterator = Packages.java.util.Iterator;
//var ListOfValuesConstraint = new Packages.org.alfresco.repo.dictionary.constraint.ListOfValuesConstraint;
var dictionaryService = ctx.getBean("DictionaryService");
‍‍‍‍‍‍‍‍‍

error log

The Web Script /alfresco/service/sita/projserv/projservregister/ has responded with a status of 500 - Internal Error.

THanks!

[mitpatoliya]

that is because both the context are different.
There are some root objects provided by Alfresco JavaScript like company_home,search, user_home etc..
but availability of those are depends on the context in which you are executing that script.

Please give details about your requirement what you are trying to achieve.

[mduduzi]

Thanks for the response.
I have defined a webscript and its javascript controller get custom constraint list to populate the drop-down in template. When the same script is tested javascript it works fine and when I deploy it as part of the webscript it complains about the package not defined.

[mduduzi]

Hi,
I have reproduce the error using a simple webscript. Pasted are files for the sample drop-down webscript:
Descriptor:

<webscript>
  <shortname>Hello</shortname>
  <description>Polite greeting</description>
  <url>/sample/dropdown</url>
  <authentication>user</authentication>
</webscript>
‍‍‍‍‍‍‍‍

Controller:

var ctx = Packages.org.springframework.web.context.ContextLoader.getCurrentWebApplicationContext();
var model = Packages.org.alfresco.model.ContentModel;
var dictionaryService = ctx.getBean("DictionaryService");
var types = dictionaryService.getSubTypes(model.TYPE_CONTENT, true).toArray();
model.yrsearch = types;
‍‍‍‍‍‍‍

Template:

<table>
   <tr>
    <td>
        <#assign props = yrsearch.properties?keys>
        <select name="idRequest" id="idRequest">
              <option value="NOT SELECTED" selected="selected">[–SELECT YEAR–]</option>
              <#list props as t>
                  <option value="${t}">${t}</option>
              </#list>
        </select>
     </td>
    </tr>
</table>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The error is the same i.e Package not defined

Please help
Thanks!

Hi Mduduzi,

As Mits told you, it's a difference in the context.
The javascript console adds some custom root-level objects (like   space) that don't exist in a normal webscript environment.
That's probably the case of Packages as well.
so your first line

var ctx = Packages.org.springframework.web.context.ContextLoader.getCurrentWebApplicationContext();‍

will fail since the "Packages" root-level object doesn't exist.

You can retrieve the list of the root-level javascript items here:

Hi Mdu

What you need to do is create a your own custom reference to a rootobject, such as Service Registry. See:
http://wiki.alfresco.com/wiki/Configuring_the_ServiceRegistry_as_a_Javascript_Root_Object

You then register a bean to that class.

e.g. I used the following java code to create my custom class:

</blockcode>
The I created a bean(-context) file:
<blockcode>
bean id="javascriptServiceRegistry" parent="baseJavaScriptExtension" class="org.alfresco.repo.extension.jscript.JavascriptCompatibleServiceRegistry">
  <property name="serviceRegistry" ref="ServiceRegistry" />
  <property name="extensionName"   value="serviceRegistry" />
/bean>
</blockcode>

In my .js controler I reference the service context as such:

<blockcode>
var dictionaryService = serviceRegistry.getDictionaryService();
var tc = serviceRegistry.getTypeContent();
types = dictionaryService.getSubTypes(tc, true).toArray();
</blockcode>
