Pasted below is the part of the script that fails and the error log:var ctx =Packages.org.springframework.web.context.ContextLo

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.

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.

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>
