How to Get Project documents and share new documents programmatically

Hello everyone,

This is Windchill API-related.

I am trying to get a Project2 object and try to get all its documents/parts that are shared.

And also try to share/unshare their associated documents. 

Doing all of these programmatically through Java code but I can not find the method to do all of these.

Any help or suggestions? Thank you!

This is my code:

String oid = "project oid";
try {
//Get document (WTDocument)
ReferenceFactory referencefactory = new ReferenceFactory();
WTReference wtreference = (WTReference) referencefactory.getReference(oid);

if (wtreference != null) {
// If wtreference exists.

Project2 project = (Project2) wtreference.getObject();
WTContainerRef ref = (WTContainerRef) referencefactory.getReference(oid);

} else{
// If wtfreference not exists.
}
} catch ( WTException ex ) {
System.out.println("Exception: " + ex);
}
