There are two things wrong with your script, firstly JavaScript and the Alfresco JavaScript API are case sensitive - so the property name is wrong, you need:

var name = person.properties.firstName;

also the document.write(…) will not work - the document.write() function is part of the web browser JavaScript extensions - the Alfresco javascript engine is pure JavaScript 1.6 with our Alfresco extensions.

Hope this helps,

Kevin

…I've just read the title of your post You can't execute Alfresco JavaScript within a JSP and expect it to work…! As i said earlier - the browser JavaScript API is very different to ours.

The Alfresco JavaScript API can executed from various hook points. It can be used in Rules - so a script can be executed say when a document is uploaded or changed or when a new space is created or similar. It is also possible to execute a script directly via URL using the command servlet. Or you can configure a script to be executed when an action icon is clicked in the web-client UI.

It cannot be used directly on a JSP page as it is executed withi the context of the server. However it can be used as part of the new Webscripts framework to build interactive pages with only some HTML/templating knowledge plus javascript:
