SDK documentation for migrating code from 2.9B to 3.0

Hi,I was wondering whether there was a documentation, or changelist about the AlfrescoEmbedded SDK. My situation is this: I am porting modules that were written for version 2.9B to 3.0. As expected, some things have changed but quite surprisingly, adapting the code was rarely more difficult than for

PageRenderer is in the
package "org.alfresco.web.framework.render.bean" of the "Web Framework" project.

Thank you for your answer. I eventually removed any reference to pageRendererServlet and HTTPProxyServlet. In fact, the code I am porting augmented web.xml with some customisations and it's working fine (for now) without these two servlets.

Hello,
I am coming back here for the same matter: some reference about what has changed. I am now facing some database schema changes. For instance, since type_qname disappeared from alf_node, I am wondering how to retrieve the uri that was previously a part of a type_qname. Should I join alf_node with alf_qname and alf_namespace ? That would be possible if alf_node.type_qname_id was a foreign key linked to alf_qname.id and alf_qname.ns_id was a foreign key for alf_namespace.id. But I am not sure of the links.

Is there any documentation that says "this is removed and replaced by…", whatever the "this" is ? My question was originally about the SDK but obviously, it's relevant for other aspects that are visible to developers. The Alfresco Labs 3 pages on the wiki did not help.

If someone could point me to somewhere, that would be great.

Unfortunaly I don't think there is any such list, to do so would be a fairly substantial task and would forever be out of date.
And the list would never include internal implementation details like how to access the database directly since that's not
something that we consider to be public facing, recommend or support.

What we do have is JIRA which will have details of all changes. And SVN will also have version history for each file, there will typically be check in comments when something is removed or changes.

But if you ask specific questions then I'm sure people such as myself can help.

OK. Thank you for these explanations.

For my database schema problem, I thought that studying the upgrade scripts would also give me some answers. I found them under WEB-INF\classes\alfresco\dbscripts\upgrade and indeed, the table 'alf_node' got a little cleaner with the two fields I mentioned earlier and which turned out being the foreign keys links I had assumed. Thanks to DH and you too, mrogers.
