Okay, so I was going through the above tutorial and was building the portal in my home. I had no problems until I landed on this chapter 'Connecting to and Managing Content
Repositories', where I have to create a content repository connection.
Now I read that I have to install the entire UCM, which is of around 3GB, and then this Oracle WebLogic Server 10.3.5.
Is it possible of not installing the above things and finish the entire tutorial? I mean some shortcut or say some dummy kind of connection. I just have a laptop with a 3GB RAM, and I really don't think its a good idea of installing the entire suite.
If you want to see how to manage content from a portal app, then you need to install content server. Portal just calls its services, and dummy server won't help you to get an impression. Besides, a lot of features are bound closely to Webcenter Content, so no other repository can't do that.
AFAIK WebCenter Portal uses RIDC, a Java API, to call some services, among them those bound to folders(collections). Some functionality would be available via JCR170, some via CMIS, but I am not aware of anyone knowing where the boundary really goes.
Btw. a similar issue will be met if you want to work with workflows - you will need a BPEL server.
