Servers in PDSOE
OpenEdge REST/Mobile applications need two types of servers
• OpenEdge AppServer (restbroker1)
• OE Web Server (restmgr1)
Servers can be stopped and started from Servers
view in PDSOE
Other Approaches
• Proenv command line
• OpenEdge Explorer / OpenEdge Management

Publishing Mobile App and Mobile Service
Complete Mobile Project constitutes both Mobile Application and Mobile Service
Same OE Web Server is used for publishing both Mobile Application and Mobile
Service
Two different .WAR files are published to OE Web Server
Publishing a mobile application does:
Fetch sources from Mobile App Builder
Package it as WAR file
Publish to Tomcat directory.
Business
Logic to
Appserver

Mobile App Builder Options in PDS OE
PDS OE allows user to perform following
options on a mobile application
Open
Run
Backup Local
Copy Source Local
Export Local
Delete
Rename
Android (.apk) and iOS (.ipa) files are
generated based on the Project Properties
settings
Deleting an application in PDSOE removes

REST Protocol OpenEdge REST
Adapter Deployment
REST and Mobile Comparison
Role of REST in Mobile Solution
REST as communication channel for Mobile Solution
REpresentational State Transfer
Simpler than SOAP web services
Client and Server communicate about the state of an
object
REST Verbs:
• GET : Requests resource
• PUT : Client posts modification of record
• POST : Client posts new creation of the record
• DELETE : Requests deletion of record

REST Protocol OpenEdge REST
Adapter Deployment
WADL Structure
WADL resembles same as that of WSDL (Web
Service Description language) for Web Services
Provides complete information about the
services that are deployed
Access to list of all resources and the parameter
information
Different tags in the WADL File
• application
• resources (base)
• resource path
• Method
• Request
• response

Why JSDO Service but not generic REST Service?
REST Hurdles:
It is possible to access data on a server prior to OpenEdge 11.2
• For example using JavaScript XMLHttpRequest( )
• Very labor intensive to write and maintain low level code
Functionality offered by JSDO:
Support for tracking changes
Transparent access to OpenEdge REST web services
Implementation details are hidden
Developers do not need to know the URIs
Local Storage and Offline transport support
Change tracking
Using generic REST Service for development in Mobile App builder will leave out JSDO
features.
