reading the value of a document property from within a behavior - alfresco

Question

question description and code was updated
Question 1: would be with what do I replace the dummy int attachmentid = 123; in the code below in order to read custom property sc:OpenERPattachmentID1 to get the id value stored in it?

}

}
#Override
public void beforeDeleteNode(NodeRef node) {
System.out.println("beforeDeleteNode!");
try {
QName attachmentID1= QName.createQName("http://www.someco.com/model/content/1.0", "OpenERPattachmentID1"); // this could/shoul be defined in your OpenERPModel-class
int attachmentid = (Integer)nodeService.getProperty(node, attachmentID1);
//int attachmentid = 123;
URL oracle = new URL("http://0.0.0.0:1885/delete/%20?attachmentid=" + attachmentid);
URLConnection yc = oracle.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
yc.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
//System.out.println(inputLine);
in.close();
} catch(Exception e) {
e.printStackTrace();
}
}
}
Question 2: where do I put the DeleteAsset.class?
I'm a Java and Alfresco novice, I'd be great if someone could tell me if alfresco-4.2.c/tomcat/webapps/alfresco/WEB-INF/classes/com/openerp/behavior/ is the right folder to put the compiled DeleteAsset.class
Question 3: What should I put in NAMESPACE and ASSET_CONTENT_TYPE?
I'd like to work without the model class as I haven't had a tutorial on that yet, what do I replace scOpenERPModel.NAMESPACE,scOpenERPModel.ASSET_CONTENT_TYPE with?
This is my full custom-web-context file:
<?xml version='1.0' encoding='UTF-8'?>

Answer 1

Well, you have a long way to go...what do you like to achieve with your "oracle" connection?
To answer your main questions: How to read a property:
Don't put the XML Model into com/openerp/model/scOpenERPModel - it should be a java class that defines constants to access your custom types, aspects & props (example: https://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/data-model/source/java/org/alfresco/model/ContentModel.java)
But that is not mandatory - it just helps you.
To read the property
inject NodeService:
private NodeService nodeService;
public setNodeService(NodeService nodeService){
this.nodeService = nodeService;
}
in your beforeDeleteNode
QName attachmentID1= QName.createQName("your sc NS uri", "OpenERPattachmentID1"); // this could/shoul be defined in your OpenERPModel-class
int attachmentid = (Integer) nodeService.getProperty(node, attachmentID1);
