Tutorial for newbies creation new content

[mstransky]

Hello,
I am new in alfresco and perhaps same as other I am facing how to customize it by developing new copoment (multicopy, specific transformation, sigantures etc…)
I use Java and SDK library using eclipse. I learned How to sign PDF document, but I am unable to create new document. Ive already spend several searching tha web without any result.
Please can someone help me?  send me some tutorial, navigate me to some wiki or to some books?
PLEASE..

Savic, thx,
actually Iam talking about java enhacement.
I found how to create new document using filefolder.create
http://wiki.alfresco.com/wiki/NodeRef_cookbook#Writing_data_to_a_node.27s_content

but still Iam facing problem with exception
User:admin ERROR [ui.common.Utils] A system error happened during the operation: Transaction didn't commit: null
javax.transaction.RollbackException: Transaction didn't commit: null

here is par of my code:
QName contentQName = QName.createQName("{http://www.alfresco.org/model/content/1.0}content");

   NodeRef directory = (NodeRef)action.getParameterValue(PARAM_SIGN_DESTINATION);
   
   FileInfo pdfInfo = fileFolderService.create(directory, "TEST.pdf", contentQName);
    NodeRef pdf = pdfInfo.getNodeRef();

We solved it.
I need to use nodeService and  forget to extend module-context.xml
