Local DevelopmentLocal Testing Support for Applications Using a Particular Database

Replace local database with

database system in the cloud

via DB tunnel

a customer installation of a database

Configuring the local server Open/config_master/connection

_data/ connection.properties

Replace with connection parameters

for desired database system*********

Local DevelopmentLocal Testing Support for Applications Using Multiple Schemas

To configure data sources as

connection properties

Open/config_master/connection_

data/ connection.properties

For every data source used by theapplication

create a database configuration with a

unique prefix to the property key

add the propertycom.sap.cloud.persistence.dsname=

Week 3 Unit 4: Consuming the

Document Service with Ext. Tools

October, 2013



Consuming the Document Service with Ext. ToolsExternal Access to Document Repository

Documents in the cloud only accessible toapps deployed in the same account

Proxy Bridge

Tunnels external CMIS requests to Document

service

Restricts access with roles or filters

Access to repository via unique name + key

Document Service

SAP HANA Cloud

Proxy Bridge

No direct

access



Consuming the Document Service with Ext. ToolsDemo: Proxy Bridge

Implement the Proxy Bridge by:

SubclassingAbstractCmisProxyServlet

Declaring the servlet in web.xml

Declaring roles to secure access

Deploying to the cloud & assigning a role

in the cockpit

Connecting to Proxy Bridge with

CMIS Workbench allows you to:

Create folders & upload files

View & edit metadata

Execute any CMIS-defined operation
