Oracle CM SDK Queries

Question

1. When a word document is edited in Webstarter Application UI, it opens the document in IE and when saved, saves it in the local machine. So,
a) How can we open the documents in the appropriate application at the client?
b) How can we program such that by default the document is saved at the same location in the Webstarter Application?
2. We want to add additional columns dynamically to the Document and Folder Object (which inherit from PublicObject) so that we can display these columns in the Webstarterapp UI. We have noticed that we can extend the attributes of the Document class in Oracle CM SDK Manager, but we are not able to specify these newly extended attribute as 'Required' (This option is disabled). Hence these attributes are not displayed in the Webstarterapp UI.
a) How can we specify the required attribute when extending the attribute of Document class?
b) Is there any other better approach to add columns dynamically?

Answer 1

a) How can we open the documents in the
in the appropriate application at the client?i haven't used webstarterapp, but you'll probably have to use some custom code which explicitly sets the document MIME type in the header of the response, and then IE will handle the document the way it is configured, opening Word Docs in Word, etc. i'm currently doing this with a custom Java app.
b) How can we program such that by default the
lt the document is saved at the same location in the
Webstarter Application?this would basically be impossible. since IE is creating a local temp file for the document at download, there's no way i can think of that a local save button in your application is going to save back to the server. and if you think about it, would you really want that? updating a document needs to be an entirely separate process.
a) How can we specify the required attribute
ribute when extending the attribute of Document
class?create a new object type in Java or XML that extends default Oracle classes, and then define your custom datatypes and other attributes. here's an example i used for testing a while back. this was for R2, so there might be slight changes to the format for CMSDK:
<?xml version="1.0" standalone="yes"?>
<CLASSOBJECT>
<NAME>CustomDocument</NAME>
<SUPERCLASS RefType="Name">Document</SUPERCLASS>
<DESCRIPTION>My extended document class.</DESCRIPTION>
<ABSTRACT>false</ABSTRACT>
<FINAL>false</FINAL>
<CLASSACL RefType="Name">CustomClassACL</CLASSACL>
<ATTRIBUTES>
<ATTRIBUTE>
<NAME>DocumentCategory</NAME>
<DATATYPE>String</DATATYPE>
<DATALENGTH>50</DATALENGTH>
<REQUIRED>true</REQUIRED>
</ATTRIBUTE>
<ATTRIBUTE>
<NAME>TrackingNumber</NAME>
<DATATYPE>Integer</DATATYPE>
<REQUIRED>false</REQUIRED>
</ATTRIBUTE>
</ATTRIBUTES>
</CLASSOBJECT>
hope that helps.
